Key Takeaways For Full Arch Photogrammetry
- Full arch workflow photogrammetry captures implant XYZ position, angulation, and platform orientation, while the intraoral scanner records soft tissue, occlusion, and the opposing arch.
- The seven-step chairside-to-lab protocol begins with preoperative records and ends with FP1-specific design and team implementation, with verification required at every checkpoint.
- Peer-reviewed studies confirm photogrammetry delivers significantly greater trueness and precision than intraoral scanning for full-arch implant cases, with mean precision errors consistently below the 75 µm clinical threshold.
- Scan body seating is the most consequential step. Incomplete seating, contamination, or micromovement create downstream framework misfit that the lab cannot correct.
- Full Arch Masters teaches the complete photogrammetry workflow inside the FAM Method, including hands-on surgical and design training with alumni access to equipment and continued case support.

Full Arch Photogrammetry Workflow Steps
This seven-step sequence moves a case from chairside capture to lab-ready data. Each step explains what the operator does, what can go wrong, and how to verify before advancing.
- Preoperative Records And Data Acquisition. Collect medical history, photographs, CBCT, and any existing prosthesis or denture records. Establish the restorative plan and document vertical dimension, occlusal scheme, and esthetic goals so every later step aligns with that plan.
- Photogrammetry And Intraoral Scanning. Thread the manufacturer’s coded scan bodies onto each implant or multi-unit abutment and hand-torque to the specified value. Confirm each scan body is clean, dry, and fully seated visually, then verify radiographically with a periapical or panoramic image, because a scan body sitting even slightly proud throws off every downstream coordinate, as the Onewd photogrammetry workflow guide documents. Once seating is confirmed, complete the intraoral scan to capture soft tissue contours, gingival architecture, the opposing arch, and the bite record.
- CBCT And Digital Treatment Planning. Use the CBCT dataset with the restorative plan to confirm implant positions relative to bone and critical anatomy. Plan any adjustments to abutment selection, angulation, or prosthetic design before committing to the final restorative path.
- exocad Design: Photogrammetry Capture And Alignment. Calibrate the photogrammetry system with the manufacturer’s device and protocol before every capture session, as the ITI clinical workflow guide by Zafar, Li, Liu, and Chen (April 14, 2026) specifies. Position the camera at the recommended working distance, then perform a full rotational sweep around the arch. Watch the software’s real-time feedback and continue until every scan body shows full intersection coverage. Capture a redundant pass so the software has more intersection points to resolve ambiguous positions.
- Immediate-Load Conversion. Use the merged photogrammetry and IOS data to design the immediate-load provisional. In same-day cases, this step converts the surgical result into a screw-retained provisional that reflects the planned occlusion and esthetics while respecting the actual implant coordinates.
- Final Zirconia Design And Finishing. Inside exocad, align the intraoral scan bodies with the standard scan body library, then match those aligned standard scan bodies with the extraoral scan bodies from the photogrammetry file. Use multiple stable reference points rather than a single landmark, because a registration error at one point can propagate into a clinically relevant misfit by the time the prosthesis is milled. Retain the raw photogrammetry file after export so any downstream error can be isolated to implant capture or soft-tissue alignment without rescanning the entire case.
- FP1-Specific Design, Team Implementation, And Workflow Scaling. Finalize FP1-specific design details, including emergence profile, cervical contours, and occlusal scheme. Check implant count and numbering, scan body library match, orientation, cross-arch distance, and occlusal plane. Train the team on each checkpoint so the workflow scales consistently across operators and locations.
Train the full photogrammetry workflow hands-on.
Why You Still Need An Intraoral Scan With Photogrammetry
Photogrammetry exports a coordinate map only: implant position, angulation, and platform orientation. It does not capture soft tissue, occlusion, or the opposing arch. As the ITI clinical guide by Zafar et al. (April 14, 2026) states, an additional intraoral scan remains necessary to capture soft tissue contours and gingival architecture for complete digital prosthesis design. The IOS provides the surface anatomy and occlusal scheme the lab needs to design against the implant coordinates.
Photogrammetry vs Intraoral Scanning For Full Arch Implants
Intraoral scanning builds its 3D model by stitching thousands of overlapping frames. On a dentate arch with abundant stable landmarks, this works well. On an edentulous full arch, the lack of natural reference objects means small stitching errors compound across the span and produce positional drift from the first implant to the last. Photogrammetry triangulates each scan body’s coordinates independently from multiple photographic angles. As a result, error does not accumulate the same way across a 14-implant full-arch case.
The peer-reviewed literature supports this distinction. A 2025 systematic review and meta-analysis by Pozzi et al. published in Clinical Implant Dentistry and Related Research concluded that photogrammetry is a more reliable technology than intraoral scanning for capturing implant positions in full-arch rehabilitations, exhibiting significantly greater trueness and precision. A 2026 in vivo crossover study by Martínez-Marugán et al. in the International Dental Journal compared six complete-arch implant impression techniques on a single patient carrying sixteen implants. The PIC system was the only technique whose mean precision error stayed consistently below the 75 μm clinical threshold. Within that threshold, 96.8% of its measurements fell, and it showed statistical superiority over all five other techniques (p < 0.001). Maximum error for the PIC system was 108 μm; for IOS (Trios) it was 476 μm.
A 2026 in vitro comparative study by Pozzi, Laureti, Marques, Fehmer, Sailer, and Azevedo in The International Journal of Prosthodontics compared intraoral photogrammetry (IPG), extraoral photogrammetry (EPG), and navigation photogrammetry (NPG) for complete-arch digital implant impressions. Global RMS trueness values were 18.10 µm for EPG, 20.00 µm for IPG, and 20.70 µm for NPG. The study concluded that all three photogrammetry modalities demonstrated high accuracy suitable for complete-arch digital impressions, with only small differences among systems.
System Comparison: iCam 4D, PIC, Medit, Shining 3D, And Straumann EXACT
The table below shows where each of the five systems fits in the full-arch workflow. The key takeaway: iCam 4D and PIC focus on implant-position capture, Medit and Shining 3D handle the IOS and IPG side, and Straumann EXACT functions as a restorative workflow platform that contains a photogrammetry step.
| System | Capture Method | Primary Workflow Role | Key Consideration |
|---|---|---|---|
| iCam 4D (Imetric4D) | Four synchronized high-resolution cameras, single distortion-free extraoral acquisition, titanium scan bodies | Implant-position capture for full-arch and full-mouth cases | Designed specifically for full-arch implant photogrammetry with open CAD/CAM workflow integration; used in more than 1 million full-arch cases per Imetric |
| PIC (PIC Dental) | Extraoral stereophotogrammetry; proprietary scan bodies; guided capture sequence | Implant-position capture for All-on-X and full-arch workflows | PIC was the only technique below 75 µm threshold in the 2026 Martínez-Marugán et al. in vivo study; proprietary scan body ecosystem; subscription-based operating model per Imetric’s published comparison |
| Medit (e.g., i700, i900) | Video-type intraoral scanning based on triangulation technology; frame stitching | IOS side of the merge: soft tissue, opposing arch, bite | Relevant as the intraoral scan partner in the merge step; Medit i700 Wireless priced approximately $21,000–$24,000 per the Conferences.Dental 2026 buyer’s guide |
| Shining 3D Aoralscan Elite | Intraoral scanning combined with integrated intraoral photogrammetry (IPG) in a single pass; two scan body sets | Combined implant-position and soft-tissue capture in one intraoral device | Shining 3D Aoralscan Elite priced approximately $20,000 with photogrammetry kit included per the Conferences.Dental 2026 guide; peer-reviewed literature on IPG accuracy is newer and thinner than for established extraoral systems |
| Straumann EXACT | Guided digital full-arch restorative workflow ecosystem; covers scanning, design, and prosthetic delivery | Restorative workflow platform tied to Straumann’s implant and prosthetic platform | Workflow ecosystem rather than a standalone capture device; photogrammetry sits inside it as the implant-position capture step; see dedicated section below |

Straumann EXACT Workflow In Full Arch Cases
Of the five systems above, Straumann EXACT works differently from the rest because it is a workflow ecosystem rather than a capture device. The Straumann EXACT™ workflow is Straumann’s digital full-arch restorative protocol, covering scanning, design, and prosthetic delivery from temporary to final restoration within Straumann’s implant and component ecosystem, compatible with Straumann UN!Q™ and the BLX, BLC, and BLT implant systems with SRA 4.6 abutment-level connections. It integrates digital scanning and prosthetic design into a structured sequence tied to Straumann’s implant platform and prosthetic components.
Photogrammetry sits inside the EXACT workflow as the implant-position capture step, recording where the implants or multi-unit abutments ended up after placement, before prosthetic design begins. EXACT functions as a workflow ecosystem tied to Straumann’s implant and prosthetic platform, while iCam 4D functions as a system-agnostic photogrammetry capture device that exports open STL and XML files for any CAD environment, including exocad. A practice running Straumann implants inside the EXACT workflow can use iCam 4D for the photogrammetry capture step and export to exocad for design, so the two systems can work together.
Scan Body Seating And Capture Protocol
Scan body seating is the single most consequential step in the photogrammetry workflow. The DESS clinical guidance identifies incomplete seating as one of the most common and underestimated sources of implant misfit in full-arch cases, because an unseated scan body records an inaccurate implant position that the lab cannot correct downstream.
The four failure modes that produce bad coordinate data are:
- Unseated scan body: Tissue, debris, or the wrong component prevents full seating. Verify visually and radiographically before capture.
- Insufficient angulation coverage: Capturing from too few angles leaves the software with insufficient intersection data, particularly for posterior implants where mouth-opening constraints limit camera access.
- Contamination: Blood, saliva, or debris on the scan body’s coded geometry prevents the camera from reading the marker. Clean and dry each scan body immediately before capture.
- Movement between captures: Any patient movement or scan body micromovement between passes introduces positional error. Under-tightened scan bodies are the most common cause.
Start by verifying seating radiographically with a periapical or panoramic image, because a scan body sitting even slightly proud throws off every downstream coordinate, as the Onewd photogrammetry workflow guide documents. Once seating is confirmed, hand-torque to the manufacturer’s specified value. Over-tightening can distort scan body geometry, while under-tightening risks micromovement during capture. With the scan bodies secure, capture with redundancy so an extra rotational pass gives the software more intersection points to resolve ambiguous scan-body positions.
Merge And Registration In exocad
The merge step combines the photogrammetry coordinate map with the IOS soft-tissue dataset inside exocad. The sequence is straightforward. First, align the intraoral scan bodies with the standard scan body library in the database. Then match those aligned standard scan bodies with the extraoral scan bodies from the photogrammetry file. The result is a merged model containing both implant coordinates and surface anatomy.
Four checkpoints catch a bad merge before the case advances to manufacturing:
- Implant count and numbering: Confirm every implant in the photogrammetry file is accounted for in the merged model with the correct position number.
- Library compatibility: The CAD library must precisely match the scan body and the physical component that will be delivered. An outdated library, incorrect platform selection, or offset discrepancy produces a framework that cannot seat regardless of scanning accuracy.
- Occlusal plane: A merged model with an incorrect occlusal plane signals a registration error. Check against the bite record and the opposing arch scan.
- Cross-arch distance: Measure inter-implant distances in the merged model against the photogrammetry file. Drift between the two datasets indicates a merge failure.
A failed merge typically presents as implant position drift when toggling between the photogrammetry file and the merged model, a library mismatch flagged by the software, or an occlusal plane that does not match the clinical bite record. The most common alignment failure is merging a clean tissue scan taken without scan bodies in place against a photogrammetry file captured with scan bodies attached, as the Onewd photogrammetry workflow guide identifies. Use multiple stable reference points rather than a single landmark, and retain the raw photogrammetry file after export so any error can be isolated to implant capture or soft-tissue alignment without rescanning the entire case.
Verification Before Manufacturing
Before the case advances to milling or printing, verify the following:
- Implant count and numbering match the clinical record
- Scan body library matches the physical component being delivered
- Implant orientation is consistent with the surgical plan
- Occlusal plane and cross-arch distance are within expected parameters
- No software warnings remain unresolved in the merge file
A verification jig or radiographic check is still indicated in complex full-arch cases. imes-icore’s April 2026 article on passive fit in full-arch implant prosthetics recommends integrating verification jigs or equivalent digital verification strategies in complex full-arch cases and states that a fully digital workflow cannot automatically guarantee passive fit. Passive fit still depends on correct scan capture, validated data, proper design, and accurate manufacturing.
A verification jig evaluates only whether the lab record matches intended implant or abutment positions. Occlusion, vertical dimension, tooth position, and esthetics require separate clinical records, prototype try-in, or other approval steps, as Times Dental Lab’s verification jig guidance clarifies.
Photogrammetry Dental Scanner Price: Dedicated Unit vs Benchtop vs Outsourced
Once the clinical workflow is verified, the next decision is how to deploy photogrammetry in the practice. Total cost of ownership depends on case volume, and the right deployment model follows from that number.
Three deployment models exist, each with a different cost structure:
- Dedicated in-office unit: Highest capital outlay, with photogrammetry systems generally priced in the five-figure range, as Dr. Richard Nejat, a board-certified periodontist who has used iCam 4D, PIC, and MicronMapper systems, notes. This model provides full control over the merge, fastest turnaround, and the ability to run same-day immediate-load cases without lab dependency. It is typically justified at higher full-arch volume, such as two or three arches per month rather than two or three per year.
- Benchtop or shared-lab capture: Lower capital outlay with moderate control over the merge and turnaround dependent on the shared facility’s schedule. This model suits practices building toward dedicated ownership.
- Outsourced: No capital outlay and a per-case fee, with the least control over the merge and turnaround dependent on the lab. As Dr. Nejat observes, many practices offering full-arch treatment either outsource the step or work without photogrammetry entirely.
Total cost of ownership includes scan bodies, kits, software fees, training, maintenance, and lab compatibility, in addition to the device itself. Private Dental Alliance’s equipment lifecycle framework places maintenance and lifecycle costs at 70–90% of the initial equipment investment over five years. Year-one maintenance runs 3–5% of purchase price, rising to 12–18% by year five. The Dental CEO Podcast’s ROI guide reports that photogrammetry systems typically achieve remake rates under 3%, compared to 8–15% for traditional impression methods, saving a practice completing 30 full-arch cases annually approximately $18,000–$27,000 in lab fees and chair time. For a solo practitioner doing two or three full-arch cases a year, hardware ROI is harder to justify than for a practice doing two or three cases a month, as the Onewd photogrammetry workflow guide notes.
Photogrammetry In Same-Day Immediate Load Cases
Beyond the cost decision, the clinical case type also determines how photogrammetry fits into the workflow. It is specifically indicated for immediate-load cases and represents one of the primary scenarios where the technology earns its place. In a same-day immediate-load protocol, scan body records are typically captured after implant placement and multi-unit abutment seating, as Triple T Dental Laboratory’s full-arch workflow guide specifies. In healed arch cases, the workflow may begin with the existing provisional or denture, healed soft tissue, and scan body records, and both pathways then move through the same provisional verification, rescan, and final bridge stages.
In immediate-load cases, fiducial marker placement should be planned before the patient leaves the chair. Maintaining stable reference points through surgery allows accurate alignment between pre-op and post-op datasets, as the Onewd photogrammetry workflow guide documents. The photogrammetry capture happens after implant placement and MUA seating and records where the implants ended up rather than where they were planned to go. That coordinate map then drives the immediate-load provisional design, which is why positional accuracy at this step directly determines whether the provisional seats without adjustment.
Where Full Arch Workflow Photogrammetry Fits In The FAM Method
Full Arch Masters teaches the full arch workflow photogrammetry end-to-end inside the FAM Method, FAM’s proprietary digital workflow for full-arch implant restoration. The same seven-step sequence described above, from preoperative records through FP1-specific design and team implementation, forms the FAM Method’s core workflow.
FAM is a certified exocad reseller for DentalCAD, exoplan, and ChairsideCAD, so all digital design instruction is taught in exocad, and alumni can purchase licenses directly through FAM at preferred pricing. Alumni also access iCam photogrammetry systems through the KOL (Key Opinion Leader) buying group at no recurring cost, which is the same buying structure that gives alumni access to Neodent implants, 3D printers, and other equipment at preferred pricing after completing any FAM course.
The lab side of the full arch workflow photogrammetry, including the merge, the exocad design, and the immediate-load conversion, is taught in the Design and Finish Course: four days in Fresno, CA, with two days of digital design in exocad and two days of aesthetic finishing on pre-sintered and post-sintered zirconia with MIYO ceramic layering. The surgical and records side, including scan body seating, photogrammetry capture, and same-day immediate-load protocol, is taught hands-on at the Live Surgical Course in Parker, CO, where Basic and Advanced operators each perform two full-arch cases on volunteer patients under mentor supervision.
When a merge goes wrong or a capture produces uncertain data, FAM alumni have access to a continued community of hundreds of FAM-trained dentists, lab technicians, and team members through private group chats. This community provides case help on demand from operators who have run the same workflow on the same equipment.
Frequently Asked Questions
Does Photogrammetry Replace The Intraoral Scanner?
Photogrammetry captures implant position, angulation, and platform orientation only. It does not capture soft tissue, occlusion, or the opposing arch, so the intraoral scanner remains necessary for complete digital prosthesis design. Photogrammetry replaces the physical impression for implant-position capture and can eliminate the verification jig step, though a separate intraoral scan is still needed for soft tissue and verification may still be advisable in complex or uncertain cases.
How Accurate Is Photogrammetry Compared To IOS For Full Arch Implants?
The 2025 Pozzi et al. systematic review cited above found photogrammetry more reliable than IOS for full-arch implant position capture. The same 2026 in vivo study cited above found the PIC system was the only technique below the 75 µm threshold. The 2026 in vitro study cited above reported the same RMS values for all three photogrammetry modalities, with in vivo results typically running wider than in vitro numbers because patient movement, saliva, and limited mouth opening are not present in bench tests.
How Do You Merge Photogrammetry And IOS Data In exocad?
In exocad, the intraoral scan bodies are first aligned with the standard scan body library in the database. Those aligned standard scan bodies are then matched with the extraoral scan bodies from the photogrammetry file to register the two datasets. Use multiple stable reference points rather than a single landmark. The most common alignment failure is merging a clean tissue scan taken without scan bodies in place against a photogrammetry file captured with scan bodies attached. Verify the merge by checking implant count and numbering, library compatibility, occlusal plane, and cross-arch distance before advancing to manufacturing.
What Does A Photogrammetry System Cost?
Dedicated photogrammetry systems are generally priced in the five-figure range. Total cost of ownership includes scan bodies, kits, software fees, training, maintenance, and lab compatibility, in addition to the device itself. The Shining 3D Aoralscan Elite, which integrates intraoral photogrammetry with surface scanning in a single device, is priced at approximately $20,000 with the photogrammetry kit included. Dedicated extraoral systems such as iCam 4D and PIC are positioned at higher price points reflecting their purpose-built full-arch photogrammetry design. Outsourced photogrammetry carries no capital outlay but a per-case fee and less control over the merge.
Dedicated Unit vs Benchtop vs Outsourced: Which Should I Choose?
The decision follows from case volume. A dedicated in-office unit is justified for practices doing two or more full-arch cases per month because it provides full control over the merge, fastest turnaround, and the ability to run same-day immediate-load cases without lab dependency. Benchtop or shared-lab capture suits practices building toward dedicated ownership. Outsourcing suits practices with low full-arch volume where the capital outlay for a dedicated unit is difficult to justify. In all three models, total cost of ownership, not sticker price, should drive the decision.
Do You Still Need A Verification Jig?
In complex full-arch cases, a verification jig or equivalent digital verification strategy remains advisable. imes-icore’s April 2026 article on passive fit recommends integrating verification jigs or equivalent digital verification strategies in complex full-arch cases and states that a fully digital workflow cannot automatically guarantee passive fit. A verification jig evaluates only whether the lab record matches intended implant or abutment positions, while occlusion, vertical dimension, tooth position, and esthetics require separate clinical records. Some validated photogrammetry workflows with experienced operators can eliminate the verification jig step, but this remains a case-by-case clinical decision.
Can Photogrammetry Be Used For All-on-4 Immediate Load?
Immediate-load All-on-X cases are one of the primary indications for photogrammetry. Scan body records are captured after implant placement and multi-unit abutment seating. Fiducial marker placement should be planned before the patient leaves the chair to maintain stable reference points through surgery. The photogrammetry coordinate map then drives the immediate-load provisional design, which is why positional accuracy at this step directly determines whether the provisional seats without chairside adjustment.
How Do You Catch A Bad Merge Before Manufacturing?
Check four things. Implant count and numbering must match the clinical record. The CAD library must match the scan body and physical component being delivered. The occlusal plane must match the bite record and opposing arch scan. Cross-arch distances in the merged model must match the photogrammetry file. A failed merge typically presents as implant position drift when toggling between the photogrammetry file and the merged model, a library mismatch flagged by the software, or an occlusal plane that does not match the clinical bite record. Retain the raw photogrammetry file after export so, if an error surfaces after the case goes to the lab, the original coordinate data lets the operator isolate whether the error originated in implant capture or soft-tissue alignment.
Conclusion: Run The Sequence And Verify Every Checkpoint
The data-division principle organizes the entire full arch workflow photogrammetry: photogrammetry captures where the implants are, the IOS captures what is around them, and CBCT captures where they sit relative to bone. Each modality answers a different clinical question. Photogrammetry replaces the physical impression for implant-position capture and can eliminate the verification jig step, while the intraoral scanner remains necessary for soft tissue and occlusion. Run the seven-step sequence, verify at every checkpoint, and the framework seats.
