Core Concepts and Clinical Context
Terminology
This guide uses specific clinical terms with precise meanings.
- Full-arch: A complete-arch implant-supported prosthesis replacing all teeth in a single arch, typically supported by four to six implants.
- Immediate load: Placement of a provisional prosthesis within 48 hours of implant surgery, before osseointegration is complete, contingent on achieving adequate primary stability.
- CBCT: Cone beam computed tomography, a three-dimensional radiographic scan used for bone volume assessment, implant planning, and surgical guide fabrication.
- Intraoral scanning (IOS): Digital capture of arch geometry using a handheld scanner, used for soft tissue morphology, occlusal records, and, with appropriate scan bodies, implant position capture.
- Photogrammetry: Extraoral or intraoral camera-based measurement of implant position using scan bodies, producing vector-based spatial coordinates rather than stitched image frames.
- FP1 / FP2 / FP3: Prosthodontic classification of full-arch restorations by the amount of replaced tissue. FP1 replaces crowns only. FP2 replaces crowns and part of the root. FP3 replaces crowns, roots, and gingival tissue.
- Surgical guide: A 3D-printed or milled template derived from CBCT and digital planning that constrains implant placement to planned positions and angulations.
- Screw-retained prosthesis: A restoration fixed to implants or multi-unit abutments with prosthetic screws rather than cement, allowing retrievability.
- Passive fit: Seating of a framework at the implant-abutment interface without generating internal stress. The framework contacts all implants simultaneously without gap, rocking, or load when screws are tightened.
Who This Workflow Serves
This workflow supports dentists, lab technicians, surgical assistants, and treatment coordinators working on full-arch cases. It applies to in-house lab models, where design and printing occur on-site, and to outsourced models where the practice captures records and a remote lab executes the CAD work. The seven FAM steps stay consistent, while handoff timing and communication protocols change by model.
U.S. Regulatory Considerations
In the United States, exocad DentalCAD functions as design software for dental professionals and laboratories, and the fabricated restorations fall under FDA oversight as medical devices. Implant library packages marked “FDA” within exocad’s integration infrastructure contain parts cleared for use in U.S. cases, and practices must confirm that the component libraries in use carry FDA clearance for the specific implant system and prosthetic interface being restored. State dental practice acts define which team members may perform clinical steps such as intraoral scanning, photogrammetry capture, and records acquisition, and these rules vary by jurisdiction.
Seven-Step exocad Immediate-Load Workflow with the FAM Method
The seven steps below outline the FAM Method as taught in the Full Arch Masters curriculum. Each step lists required inputs, stakeholders, tools, decision points, timing, and handoff considerations.
Step 1: Preoperative Records and Data Acquisition
Inputs: Patient medical and dental history, existing radiographs, photographs, occlusal records, and any existing prosthetics or dentures.
Stakeholders: Dentist, surgical assistant, treatment coordinator.
Tools: Intraoral scanner, facial scanner, digital photography system, occlusal registration materials.
Timing: Completed at the consultation or a dedicated preoperative appointment, typically 60–90 minutes.
Decision points: Confirm arch classification (FP1, FP2, or FP3) first, because this defines the amount of tissue replacement required and constrains the design approach. Next, assess the existing vertical dimension of occlusion; if the patient’s current VDO is acceptable, a denture conversion may preserve it more reliably than a full digital design. Use these two assessments together to decide whether a denture conversion or full digital design is the appropriate provisional strategy for the case.
Handoff: Organize all records in DentalDB before CBCT acquisition. In a solo-dentist office, the assistant manages scan capture while the dentist reviews records. In a multi-provider group, a dedicated records coordinator may execute this step independently.
Step 2: Photogrammetry and Intraoral Scanning
Inputs: Placed implants with scan bodies seated, soft tissue in post-surgical state.
Stakeholders: Surgical assistant handles scan capture, the dentist verifies results, and the lab technician receives the data.
Tools: Photogrammetry system (for example, Imetric iCam4D) and an intraoral scanner for soft tissue and opposing arch.
Timing: Performed immediately after implant placement, with photogrammetry capture typically taking 10–20 minutes per arch.
Passive fit represents the primary technical risk in full-arch screw-retained prosthetics, and the acquisition phase is where irreversible error enters the workflow. If acquisition data from intraoral scanning or photogrammetry is inaccurate, downstream CAD design cannot recover the lost positional truth, which creates a cascading accumulation of cumulative error. Photogrammetry addresses this risk by capturing implant positions as vector-based spatial coordinates rather than stitched image frames. Intraoral scanners build full-arch models by stitching sequential image frames, and each stitch introduces small error that compounds across a long edentulous span between implants. Photogrammetry removes this stitching step and offers improved trueness for full-arch implant position capture.
Decision points: Verify scan body seating before capture. Confirm that photogrammetry data merges with the IOS soft tissue scan before transfer to planning software. Photogrammetry data still requires integration with intraoral scanner datasets to capture soft-tissue morphology, which adds workflow complexity even though implant positional accuracy is superior.
File types at handoff: The following table summarizes the three critical file types that must be transferred at this step, and missing any one will cause the design step to fail or produce an inaccurate restoration.
| Data Type | Format | Purpose | Warning |
|---|---|---|---|
| Photogrammetry implant positions | XML / proprietary export | Implant coordinate reference for exocad | Must match installed implant library in DentalCAD |
| Soft tissue / opposing arch | STL or PLY | Occlusal design and emergence profile | PLY required for color data in Smile Creator |
| Full case project | dentalProject folder | Complete case transfer between workstations | Copying only the dentalProject file without supporting data causes exocad to open the case empty or fail to load |
Step 3: CBCT and Digital Treatment Planning
Inputs: CBCT DICOM data, preoperative IOS scans, photogrammetry records, and patient prosthetic goals.
Stakeholders: The dentist leads planning, the surgical assistant manages guide fabrication, and the lab technician aligns design data.
Tools: Implant planning software (for example, exoplan), CBCT viewer, and a surgical guide design and printing workflow.
Timing: Completed before surgery day, with planning sessions typically 30–60 minutes per arch.
Decision points: Confirm implant positions, angulations, and emergence trajectories. Identify screw channel access points before design begins, because correcting channel emergence in exocad later consumes significantly more time than planning it upstream. Implant position data for All-on-X modeling in exocad is most reliable when imported directly from the surgical plan generated by implant planning software, which allows the CAD workflow to begin with accurate implant locations rather than manual placement.
Handoff: Export STL or PLY mesh from planning software for import into DentalCAD. Confirm that the implant system, multi-unit abutment type, and Ti-base specifications are documented before the lab opens the case.
Step 4: exocad Design
Inputs: Merged photogrammetry and IOS dataset, CBCT-derived implant positions, and a clear prosthetic prescription (FP1, FP2, or FP3, material, occlusal scheme).
Stakeholders: The lab technician serves as primary designer, and the dentist provides approval.
Tools: exocad DentalCAD 3.3 Chemnitz, Implant Module, Bar Module, Provisional Module, and DentalDB.
Timing: An experienced designer typically requires 60–120 minutes for a standard full-arch provisional.
Library setup often causes design failure at this step. exocad’s implant library integration requires the correct implant and Ti-base or prosthetic component libraries to be installed for the specific system being used; these libraries are accessed through exocad’s integration infrastructure and total more than 9,000 packages containing 80,000+ scanbodies, titanium bases, custom, stock, and standard abutments, Multi-Units, and model lab analogs that are updated daily. Implant libraries must be installed in the DentalCADApp/library/implant folder while the program is closed, the previous version of the library should be deleted first, and double-nested folders must be avoided or the system will not recognize the library.
For bar-supported designs, DentalCAD 3.3 Chemnitz introduced a split denture workflow inside the Bar Module that enables users to design the bar and superstructure for implant-supported full-arch restorations in a single guided workflow before automatically splitting them into two precisely matching components. The split denture workflow supports a backward-planning approach that begins with the definitive restoration design before segmenting it and generating the framework, and it integrates directly into DentalDB with options such as “Design bar?” that can be activated in wizard or expert mode.
Passivity check at design stage: Confirm in the software’s 3D view that the virtual framework seats simultaneously at all implant interfaces without gap or rocking before exporting for fabrication. A mismatch between the CAD/CAM library and the physical component, caused by an outdated library, incorrect platform selection, or offset value discrepancies, produces a framework that cannot seat correctly regardless of scanning accuracy.

Step 5: Immediate-Load Conversion
Inputs: Approved exocad STL and XML export, 3D printer loaded with appropriate resin (PMMA or equivalent), and multi-unit abutments seated intraorally.
Stakeholders: The lab technician manages printing and finishing, the surgical assistant supports chairside try-in, and the dentist verifies occlusion and delivers the prosthesis.
Tools: 3D printer (for example, Envisiontec or DentaFab Sega Pro), post-processing unit, prosthetic screwdriver, and torque wrench.
Timing: Print and post-process typically require 45–90 minutes, and chairside try-in and delivery require 30–45 minutes.
Decision points: Confirm passive seating using the one-screw test before full torque. When a framework does not seat passively in a full-arch restoration, tightening prosthetic screws masks the mismatch temporarily but leads to recurrent screw loosening, micromotion, marginal bone loss, screw fracture, or implant failure. If rocking appears, return to the acquisition data before proceeding.
Handoff: Document screw torque values, access hole positions, and occlusal contacts at delivery. This record becomes the baseline for the final restoration appointment.
Step 6: Final Zirconia Design and Finishing
Inputs: Validated immediate-load provisional, updated soft tissue scan at the appropriate healing interval, and a confirmed occlusal scheme.
Stakeholders: The lab technician manages design and finishing, and the dentist approves and delivers the final restoration.
Tools: exocad DentalCAD (Implant Module and Bar Module for bar-retained designs), zirconia milling unit or outsourced milling center, sintering furnace, and MIYO ceramic layering materials.
Timing: Design sessions typically require 60–120 minutes, and milling, sintering, and finishing require 1–3 days depending on in-house versus outsourced milling.
The passive fit requirement discussed in Step 5 applies equally to the final zirconia restoration. Framework fabrication method affects passive fit outcomes, and laboratory studies comparing milled Co-Cr, SLM 3D-printed, and conventionally cast frameworks report gaps within clinically acceptable ranges when upstream acquisition and design steps are accurate.
Decision points: Confirm material selection (zirconia, PMMA, PEEK, metallic framework, or crystal-based material) against case requirements and patient function. For bar-retained designs, use the DentalCAD 3.3 Chemnitz split denture workflow to generate bar and superstructure as matched components. The bar substructure can be fabricated from titanium, PEEK, or other materials while the superstructure uses zirconia, resin composites, or ceramic composites, which preserves aesthetics while adding stability and passive fit for All-on-X restorations.
Step 7: FP1-Specific Design and Scaling the Team Workflow
Inputs: Case classification confirmed as FP1 (crown-only replacement), root banking plan if applicable, and a team trained on role-specific responsibilities.
Stakeholders: The dentist manages case selection and surgical approach, the lab technician executes FP1-specific design in exocad, the surgical assistant handles records and chairside delegation, and the treatment coordinator manages the case pipeline.
Tools: exocad DentalCAD with FP1-specific library configuration, team SOPs, and delegation checklists.
Timing: FP1 design differs from FP2 and FP3 in emergence profile, root banking integration, and aesthetic finishing requirements, so designers should add 20–40 minutes to standard design time for unfamiliar cases.
Decision points: FP1 does not suit every full-arch patient and requires adequate bone volume, favorable gingival architecture, and aesthetic expectations that align with a crown-only replacement. Confirm these three criteria before committing to the FP1 pathway, because selecting FP1 for a case that requires tissue replacement creates an aesthetic failure. Once FP1 case selection is reliable, team capacity becomes the next constraint; when scaling to multiple arches per week, confirm that team delegation is documented in SOPs so the dentist does not become the bottleneck at non-billable steps.
Handoff: At this stage, the workflow shifts from individual case execution to system-level scaling. Document turnaround times, remake rates, and team utilization per case. Use this data to identify the next constraint, whether that is scan capture speed, design throughput, or treatment coordinator pipeline management.

Frameworks and Checklists for Reliable Team Execution
The seven steps above describe what happens in the FAM Method workflow. The frameworks and checklists in this section describe who executes each step and how to maintain quality as volume scales. The FAM Method functions as a team system, and role mapping, which assigns specific steps to specific team members, converts a workflow learned in a course into a workflow that runs reliably in a practice.
Role-Mapping by Practice Model
In a single-dentist office without an in-house lab technician, the dentist and surgical assistant share responsibility for Steps 1–3 and 5, while design in Step 4 is outsourced to a remote lab. The critical handoff is the data package, and the complete dentalProject folder, the photogrammetry export, the implant system specification, and the prosthetic prescription must all be transmitted together. Missing any element adds a revision round and delays the provisional.
In a multi-provider group with an in-house lab technician, Steps 4 and 6 move in-house. The lab technician handles DentalCAD design and finishing while the surgical team runs the clinical steps in parallel. This model supports higher case volume because design and fabrication do not wait on external lab turnaround.
Quality-Control Checkpoints
- Pre-scan: Confirm scan body seating and library match before photogrammetry capture.
- Pre-design: Verify that the implant library version in DentalCAD matches the physical component on the patient.
- Pre-print: Review STL and XML export for completeness, and confirm printer resin is within manufacturer shelf life.
- Pre-delivery: Perform a one-screw passive fit test before full torque on all prosthetic screws.
- Post-delivery: Document occlusal contacts, screw torque values, and access hole positions in the patient record.
Common Challenges and Troubleshooting
Library Mismatches
Observable sign: exocad cannot locate the implant component, or the virtual abutment does not match the physical hardware on the model.
Immediate workaround: Use exocad’s Library Manager to identify the correct package and install it before reopening the case. Do not proceed with a mismatched library, because the resulting framework will not seat correctly.
Longer-term improvement: Maintain a library version log tied to the implant systems used in the practice. Update libraries as part of a scheduled software maintenance protocol, not reactively during a case.
Photogrammetry-to-exocad Transfer Errors
Observable sign: Implant positions in DentalCAD do not match the clinical photograph or the surgical plan.
Root cause: Incomplete dentalProject folder transfer or photogrammetry export not merged with the IOS soft tissue scan before import.
Immediate workaround: Return to the raw photogrammetry data and re-export using the correct file format for the implant planning software in use. Confirm that the STL or PLY mesh is the correct interoperability format for the planning-to-DentalCAD handoff.
Longer-term improvement: Standardize a pre-design checklist that requires confirmation of four data elements, which include photogrammetry export, IOS soft tissue scan, opposing arch scan, and implant system specification, before the designer opens the case in DentalCAD.
Screw-Channel Emergence Issues
Observable sign: Screw channel exits through the facial surface of a tooth or is inaccessible for a standard screwdriver.
Root cause: Implant angulation not accounted for during treatment planning in Step 3, or implant position data not accurately transferred from planning software to DentalCAD.
Immediate workaround: Use angled screw channel abutments if available for the implant system, or redesign the affected tooth position to accommodate the channel trajectory.
Longer-term improvement: Map screw channel trajectories in the planning software during Step 3 before surgery. Confirm access point locations on the virtual prosthesis before the surgical guide is printed.
Team Handoff Friction
Observable sign: Design delays, missing data at the lab, or the dentist re-entering the workflow to locate information the lab technician needs.
Root cause: Undefined handoff protocol with no standard data package and no named responsible party for each transfer step.
Immediate workaround: Create a case checklist that travels with the dentalProject folder and must be signed off by the sending team member before transfer.
Longer-term improvement: Build the handoff checklist into the practice’s SOP library and train every team member on it during onboarding.
Measuring Success
The FAM Method targets a 2–4 hour turnaround from implant placement to screw-retained provisional delivery. Tracking the following metrics per case shows where the workflow performs well and where it loses time. Start with turnaround time and remake rate, because these two metrics reveal whether the workflow is fast and accurate. Once those stabilize, add passivity verification to confirm quality at delivery. Case acceptance rate and team utilization act as leading indicators, because case acceptance predicts future volume and team utilization predicts whether the practice can handle that volume without the dentist becoming the bottleneck.
- Turnaround time: Clock from implant placement to provisional delivery. Log by step to identify the bottleneck in acquisition, design, or fabrication.
- Remake rate: Track provisionals and finals that required redesign or refabrication. A remake rate above 5% warrants a root-cause review of the acquisition or design step.
- Passivity verification: Document one-screw test results at every delivery. Any rocking or gap triggers a return to acquisition data before proceeding.
- Case acceptance rate: Track full-arch consultations to signed treatment plans. A declining acceptance rate signals a treatment coordination issue rather than a clinical one.
- Team utilization: Measure how many steps the dentist executes personally versus those delegated to trained team members. High dentist utilization on non-billable steps such as scan capture, data transfer, and printing reveals a delegation gap.
Conduct a monthly case-review meeting with the full team, including dentist, assistant, lab technician, and treatment coordinator, to review these metrics and identify one improvement per cycle. Practices that build this review into their operating rhythm scale faster than those that treat each case as a standalone event.
Advanced Considerations and Iteration
The sections above establish the foundational FAM Method workflow and the metrics that confirm it runs reliably. Once the seven-step FAM Method delivers consistent 2–4 hour turnaround, remake rates below threshold, and passive fit at every delivery, the next iteration focuses on volume scaling and case complexity expansion.
Scaling Volume
Team capacity, not clinical skill, usually limits growth from two arches per month to five or more. Delegation frameworks that move scan capture, data transfer, and print management to trained assistants and lab technicians free the dentist’s chair time for billable clinical steps. Practices that have adopted the FAM Method report adding more than $1M per year in practice revenue, driven by a faster workflow running more arches at higher margin rather than a higher per-case fee.
Expanding to Atrophic Arches
Atrophic arches, which include patients with significant bone loss requiring zygomatic, pterygoid, trans-sinus, or palatal-approach implants, use the same seven-step digital workflow with additional surgical planning complexity. The exocad design steps in Steps 4–6 remain unchanged, and the difference appears upstream in CBCT planning in Step 3 and in surgical execution. Readiness criteria for atrophic cases include consistent passive fit on standard arches, a team that runs the digital workflow without supervision, and surgical mentorship for the advanced placements.
Standardizing Across Locations
Multi-location groups that standardize the FAM Method across sites need identical library configurations in DentalCAD at every workstation, a shared SOP library accessible to all team members, and a case-review cadence that includes representatives from each location. Library version control often becomes the primary failure point in multi-site rollouts.
Continuing Education
Full Arch Masters courses carry continuing education credits through the Academy of General Dentistry (AGD) PACE program, generally 32 CE credits per main course. The FAM Fellowship delivers more than 90 CE hours across the full curriculum. Maintaining CE compliance while building full-arch volume matters for dentists in states with annual CE requirements.
Frequently Asked Questions
How long does it realistically take to deliver a same-day full-arch provisional using the FAM Method?
The 2–4 hour target mentioned earlier assumes photogrammetry capture is completed immediately post-placement, the design workstation is set up with correct libraries before surgery day, and the 3D printer is loaded and ready. First cases at a practice new to the workflow typically run longer, often 4–6 hours, as the team builds speed at each handoff. Consistent 2–4 hour delivery becomes achievable within the first several cases when the team has trained together on the full sequence.
What equipment categories does a practice need to run this workflow in-house?
The core equipment categories include an intraoral scanner for soft tissue and opposing arch capture, a photogrammetry system for implant position acquisition, and CBCT imaging either in-house or via referral. A workstation running exocad DentalCAD with the Implant Module, Bar Module, and Provisional Module handles design. A 3D printer fabricates the immediate-load provisional, and post-processing equipment finishes the printed provisional. Practices that outsource the final zirconia restoration do not need a milling unit or sintering furnace in-house. The specific hardware within each category varies, and Full Arch Masters’ KOL buying group provides alumni access to preferred pricing on vetted systems across these categories.
What are the U.S. regulatory considerations for in-house fabrication of full-arch provisionals?
In the United States, dental restorations fabricated in-house using 3D printing or milling qualify as medical devices under FDA oversight. Practices must confirm that the component libraries in use carry FDA clearance for the specific implant system and prosthetic interface being restored. State dental practice acts govern which team members may perform clinical steps such as intraoral scanning, photogrammetry capture, and records acquisition, and these requirements vary by jurisdiction.
