Learn the complete system at <a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.fullarchmasters.com\/\">Full Arch Masters<\/a>.<\/p>\n<\/li>\n<\/ul>\n<p>The following seven-stage process shows how these principles work in real cases. Each stage builds on the accuracy and verification completed in the previous step.<\/p>\n<h2>Seven Stages of a Same-Day Digital Full-Arch Workflow<\/h2>\n<h3>Stage 1: Pre-Operative Records Capture (15 min)<\/h3>\n<p>The surgical assistant captures a full facial scan, an intraoral scan of the existing dentition or edentulous ridge, and a CBCT. All three datasets are exported as STL and DICOM files and uploaded to the planning software before the patient leaves the chair. The assistant confirms scan body seating visually and with tactile resistance at this stage. Unseated scan bodies are a primary source of downstream misfit and must be corrected now rather than at delivery.<\/p>\n<h3>Stage 2: CBCT and Photogrammetry Integration (20 min)<\/h3>\n<p>The DICOM from the CBCT merges with the STL surface scan in exoplan. Bone volume, nerve position, and sinus floor are mapped. Implant positions are virtually planned to the prosthetic outcome, so the workflow remains prosthetics-first rather than anatomy-first. This merge step functions as the first exocad checkpoint, where the clinician confirms that the planned emergence profiles are realistic before ordering any implants.<\/p>\n<h3>Stage 3: Surgical Planning and Guide Fabrication (30 min)<\/h3>\n<p>The surgical guide is designed in exoplan and sent to the in-office 3D printer. <a target=\"_blank\" rel=\"noindex nofollow\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12967805\">SLA, DLP, and PolyJet printing technologies are clinically acceptable for full-arch guide production<\/a>, while FDM is not. The printed guide is verified on the pre-op model before sterilization. At the same time, the lab technician opens the pre-op scan in exocad DentalCAD and starts the immediate-load prosthesis shell, including tooth form, arch width, and vertical dimension, so design work runs in parallel with surgical preparation.<\/p>\n<h3>Stage 4: Implant Placement and Immediate Photogrammetry (45 min)<\/h3>\n<p>The dentist places implants through the surgical guide. Immediately after placement, the team seats photogrammetry scan bodies and uses the photogrammetry device, in the FAM Method the iCam4D from Imetric4D, to capture implant positions. Studies show the iCam4D can achieve high accuracy for implant positions, and <a target=\"_blank\" rel=\"noindex nofollow\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12937834\">the G\u00f3mez-Polo 2023 systematic review evaluated the iCam4D system<\/a>. A secondary intraoral scan records soft tissue and emergence profiles, and a small titanium fiduciary marker allows exocad to merge the two datasets. This photogrammetry-first capture forms the accuracy foundation of the entire workflow and serves as the direct input for the design phase that follows. No current intraoral scanner can reliably capture full-arch implant positions with the accuracy needed for passive fit due to cumulative stitching distortion across the arch.<\/p>\n<h3>Stage 5: exocad Design of Immediate-Load Prosthesis (40 min)<\/h3>\n<p>The lab technician imports the photogrammetry file into exocad DentalCAD and merges it with the pre-surgical shell. Implant positions are checked against the surgical plan, and the immediate-load PMMA prosthesis is finalized. The second exocad checkpoint occurs here. Occlusal contacts, interproximal contacts, screw-access channel angulation, and arch form are reviewed before sending the file to print. Any angular deviation flagged by the software triggers a review of the photogrammetry capture rather than a design workaround.<\/p>\n<h3>Stage 6: 3D Printing and Finishing (60 min)<\/h3>\n<p>The approved STL goes to the in-office printer. PMMA resin serves as the material of choice for the immediate-load provisional because it prints and post-processes within about an hour. The lab technician polishes and characterizes the prosthesis, then verifies screw-access channel alignment on the printed prosthesis against the analog model before it leaves the bench. Digital workflows shorten laboratory turnaround times in conventional lab-to-practice models, and in-office printing compresses that window further so delivery fits within the surgical appointment.<\/p>\n<h3>Stage 7: Delivery and Final Seating (30 min)<\/h3>\n<p>The team seats the prosthesis over the multi-unit abutments. The Sheffield one-screw test follows. The most distal screw is finger-tightened, and all other implant-abutment interfaces are checked for gaps or lifting. Any lifting at an unscrewed interface indicates absence of passive fit and requires correction before full torque. Periapical radiographs confirm marginal contact at every interface. Screws are torqued to manufacturer specification, access channels are sealed, and occlusion is verified in centric and lateral excursions. The patient leaves with a screwed-in, same-day restoration, and total chair time remains within 2\u20134 hours.<\/p>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.fullarchmasters.com\/\">Practice this seven-stage sequence on live patients under expert mentor supervision at an upcoming Full Arch Masters course.<\/a><\/p>\n<p>While the seven-stage process provides the operational framework, consistent passive fit depends on three verification checkpoints built into the workflow. These checkpoints catch errors early so they do not compound into remakes.<\/p>\n<h2>Verification and Passive-Fit Protocols for Long-Term Stability<\/h2>\n<p>Passive fit means the prosthesis seats at the implant-abutment interface without internal stress, rocking, or load when screw-retained. This condition is a biomechanical prerequisite for long-term stability. Clinically acceptable marginal discrepancy is a key factor for implant frameworks, and studies show that standard clinical tests can identify many fully digital full-arch frameworks as non-passive, which means visual and tactile checks alone do not provide enough protection.<\/p>\n<p>Because visual and tactile checks miss critical discrepancies, the FAM Method enforces three quantitative verification checkpoints at different stages of the workflow:<\/p>\n<ul>\n<li>\n<p><strong>Photogrammetry RMS review (CCP-1):<\/strong> Before any CAD execution, the team evaluates the RMS deviation of the photogrammetry capture. <a target=\"_blank\" rel=\"noindex nofollow\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12937834\">Fu et al. demonstrated a statistical correlation between RMS deviation of the initial scan and marginal misfit of the final milled framework<\/a>, which supports quantitative pre-manufacturing accuracy checks. If the RMS exceeds the 50 \u00b5m working threshold, the team repeats the photogrammetry capture before design proceeds.<\/p>\n<\/li>\n<li>\n<p><strong>Verification jig try-in:<\/strong> For complex cases or large inter-implant spans, the lab fabricates a rigid splinted verification jig and tries it in intraorally to confirm that the digital model matches actual implant positions. Manual testing with a dental explorer can miss gaps smaller than 60\u2013120 \u00b5m, so radiographic confirmation accompanies every jig try-in. When photogrammetry serves as the primary capture method, <a target=\"_blank\" rel=\"noindex nofollow\" href=\"https:\/\/imetric4d.com\/how-icam-works\/\">the iCam system captures implant positions with under 5-micron accuracy<\/a>, which allows labs to proceed directly to substructure milling without a verification jig in straightforward cases.<\/p>\n<\/li>\n<li>\n<p><strong>Sheffield one-screw test at delivery:<\/strong> The Sheffield test requires seating the prosthesis, finger-tightening only the most distal screw on one side, then visually and radiographically checking all other implant-prosthesis interfaces for gaps. The process is repeated on the opposite distal screw. Any gap triggers a return to the photogrammetry dataset before the case is closed.<\/p>\n<\/li>\n<\/ul>\n<p>A multi-unit implant prosthesis that fits passively can deliver 20+ years of clinical service, while one that does not may fail within 24 months or accelerate marginal bone loss around supporting implants.<\/p>\n<h2>Team Delegation and Handoff Checkpoints<\/h2>\n<p>The FAM Method runs on one team and one workflow, with every role carrying defined responsibilities. This delegation structure keeps the dentist\u2019s chair time focused on billable clinical work rather than records acquisition or file management.<\/p>\n<ul>\n<li>\n<p><strong>Dentist \/ practice owner:<\/strong> Approves the surgical plan in exoplan, performs implant placement, confirms photogrammetry scan body seating, executes the Sheffield test and final torque at delivery, and signs off on the exocad design before printing.<\/p>\n<\/li>\n<li>\n<p><strong>Lab technician:<\/strong> Receives the pre-op scan and begins the prosthesis shell during Stage 3, imports the photogrammetry file and finalizes the immediate-load design in exocad during Stage 5, and manages printing, post-processing, and bench verification during Stage 6.<\/p>\n<\/li>\n<li>\n<p><strong>Surgical assistant:<\/strong> Captures all pre-operative records during Stage 1, seats and confirms photogrammetry scan bodies during Stage 4, manages the photogrammetry device, and merges the soft-tissue intraoral scan with the photogrammetry file for handoff to the lab technician.<\/p>\n<\/li>\n<li>\n<p><strong>Treatment coordinator:<\/strong> Confirms the patient\u2019s financing and consent documentation before the appointment begins, manages patient communication during the surgical and printing phases, and schedules the follow-up occlusal check at the time of delivery.<\/p>\n<\/li>\n<\/ul>\n<h2>Measuring Success in a Digital Full-Arch Workflow<\/h2>\n<p>Four practical metrics define a functioning fully digital full-arch restoration workflow:<\/p>\n<ul>\n<li>\n<p><strong>Passive fit on first seating:<\/strong> The prosthesis seats without rocking, gaps, or resistance at any implant-abutment interface on the first attempt. Repeated Sheffield failures point to a photogrammetry capture or scan body seating problem earlier in the process.<\/p>\n<\/li>\n<li>\n<p><strong>Total chair time under 4 hours:<\/strong> The 2\u20134 hour window serves as the operational benchmark of the FAM Method. Cases that consistently run longer usually indicate a delegation bottleneck, often the dentist performing tasks that the surgical assistant or lab technician should own.<\/p>\n<\/li>\n<li>\n<p><strong>Remake rate below 3%:<\/strong> Traditional analog implant workflows often show higher remake rates, while digital workflows can achieve lower remake rates. A remake rate above 3% in a fully digital workflow usually traces back to a specific failure point such as scan body seating, photogrammetry calibration, or exocad design review, which can be isolated and corrected.<\/p>\n<\/li>\n<li>\n<p><strong>Revenue impact of increased case volume:<\/strong> The faster workflow directly enables more arches per week, which translates to measurable revenue growth. The compressed timeline allows practices to accept more cases at higher margin, while a trained treatment coordinator running a documented pipeline converts those opportunities into closed revenue.<\/p>\n<\/li>\n<\/ul>\n<h2>Common Challenges and Troubleshooting Tips<\/h2>\n<ul>\n<li>\n<p><strong>Scan body seating errors:<\/strong> If a scan body is not fully seated and stable before photogrammetry capture, the recorded implant position is inaccurate and the resulting framework cannot seat passively. The mitigation protocol asks the surgical assistant to confirm each scan body with tactile resistance and a periapical radiograph before activating the photogrammetry device. Any scan body that moves during capture triggers a full re-capture of that position.<\/p>\n<\/li>\n<li>\n<p><strong>Soft-tissue integration:<\/strong> Photogrammetry records implant positions but not soft tissue. A secondary intraoral scan merged via a small titanium fiduciary marker completes the digital model and integrates gingival architecture. The merge must be confirmed in exocad before design proceeds, because a failed merge produces a prosthesis with incorrect emergence profiles.<\/p>\n<\/li>\n<li>\n<p><strong>Software merging issues:<\/strong> CBCT DICOM and photogrammetry STL files must share a common coordinate system for accurate registration. Calibration inconsistencies and software coordinate merging errors are key technical challenges in photogrammetry for full-arch cases. Mitigation includes using the same scan body library across all software platforms, confirming calibration of the photogrammetry device at the start of each session, and validating the merged file in exocad at CCP-1 before any design work begins.<\/p>\n<\/li>\n<li>\n<p><strong>Photogrammetry capture conditions:<\/strong> <a target=\"_blank\" rel=\"noindex nofollow\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12944613\">Photogrammetry is sensitive to acquisition conditions including lighting, surface texture, and reflectance<\/a>. Mitigation includes standardizing the operatory lighting setup, using matte-finish scan bodies to reduce specular reflection, and retaking any capture where the device flags a calibration warning.<\/p>\n<\/li>\n<\/ul>\n<h2>FAQ<\/h2>\n<h3>What photogrammetry accuracy is required for a passively fitting full-arch restoration?<\/h3>\n<p>The clinical threshold for implant framework marginal discrepancy plays a central role in passive fit. Photogrammetry systems can deliver the trueness needed below typical thresholds for passive fit, and the iCam4D system used in the FAM Method has shown strong trueness values across published studies. By comparison, intraoral scanners introduce positional errors that make them unsuitable for full-arch implant cases where passive fit is required. In practice, photogrammetry offers a clear advantage for four-or-more-implant full-arch cases when passive fit on first seating is the standard.<\/p>\n<h3>How long does a fully digital full-arch workflow actually take from surgery to delivery?<\/h3>\n<p>Under the FAM Method, the total time from patient arrival to a screwed-in same-day restoration ranges from 2 to 4 hours. The approximate breakdown across the seven stages is pre-operative records at 15 minutes, CBCT and photogrammetry integration at 20 minutes, surgical planning and guide fabrication at 30 minutes, implant placement and immediate photogrammetry at 45 minutes, exocad design at 40 minutes, 3D printing and finishing at 60 minutes, and delivery with verification at 30 minutes. Parallel workflow enables this timeline because the lab technician begins the prosthesis shell during surgical preparation, so design and printing run concurrently with post-surgical steps instead of waiting until after the patient leaves. Hybrid workflows, where lab work starts only after the appointment, cannot reach same-day delivery regardless of how many digital tools the practice owns.<\/p>\n<h3>Is a verification jig still necessary when photogrammetry is used?<\/h3>\n<p>Straightforward cases with photogrammetry capture inside the RMS working threshold and radiographically confirmed scan body seating can often skip the verification jig appointment, which creates one of the documented efficiency gains of photogrammetry-first workflows. Complex cases with large inter-implant spans, significant angulation, or any flagged deviation at CCP-1 still benefit from a verification jig try-in before final framework fabrication. The Sheffield test is performed at delivery in every case because it provides final clinical confirmation of passive fit, a step that remains mandatory regardless of upstream verification methods.<\/p>\n<h3>What is the realistic remake rate for a fully digital full-arch workflow, and what drives it above target?<\/h3>\n<p>A well-executed fully digital workflow should hold the remake rate at or below 3%. The most common drivers of higher remake rates include scan body seating errors caught too late, photogrammetry calibration drift that went unnoticed at CCP-1, and exocad design files approved without a second-technician review of occlusal contacts and screw-access channel angulation. Each of these problems reflects a process failure rather than a technology failure, which means teams can correct them through delegation protocols and defined checkpoints instead of equipment upgrades. Practices that implement the full FAM Method delegation checklist, including the CCP-1 RMS review and the pre-print design sign-off, consistently achieve remake rates at or below the 3% benchmark.<\/p>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.fullarchmasters.com\/\">Implement the complete FAM Method in your practice by registering for an upcoming course to master photogrammetry capture, exocad checkpoints, delegation protocols, and same-day delivery.<\/a><\/p>\n<h2>Conclusion<\/h2>\n<p>The gap between a hybrid workflow and a fully digital full-arch restoration workflow reflects a gap in system rather than a gap in equipment. Photogrammetry-first capture, parallel lab design, defined exocad checkpoints, and a trained team executing one workflow together compress a multi-day, multi-appointment process into a 2\u20134 hour same-day delivery. The FAM Method provides that system as a complete, repeatable sequence taught by a cross-trained instruction team that runs it on live patients every week. The recipe exists, and practices that adopt it can move from occasional hybrid cases to predictable, fully digital same-day full-arch delivery.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Full Arch Masters&#8217; 7-stage digital full arch workflow delivers same-day screw-retained restorations, passive fit, and sub-3% remake rates.
