How to Send Your First All-on-X Case to a Lab: A Clinician's Field Guide

Your first All-on-X case is not the place to learn what your lab needs by getting a phone call three days after submission. Full-arch immediate-load cases have too many dependencies, and the prosthetic timeline is unforgiving when the intake data is thin. This guide walks the submission end to end, from the surgical planning session to the day the final zirconia bridge seats.

The framing assumption: you are shipping to a lab that runs the digital workflow start-to-finish. Guide design, provisional, custom abutments, final prosthetic, all in-house. That single-vendor model is what makes the timeline defensible. If your case is passing through three vendors, the coordination overhead alone will add two to four weeks, and this guide will not save you.

Before the case leaves your operatory

All-on-X submissions fail at intake more than they fail at fabrication. The lab can execute clean on bad data, but the case that comes back will be the case the data described, not the case you had in your chair. Five inputs need to be complete before you package anything.

First, the CBCT. Full field of view, both arches captured, patient in maximum intercuspation if any teeth remain. DICOM export, not the compressed viewer file. If you are using a scanner that outputs a proprietary format, include the neutral DICOM alongside it. The lab needs bone density readable at the planned implant sites, not just visualized.

Second, the intraoral scan. Both arches, bite registration, and if the patient is fully edentulous, a scan of the existing denture serves as the reference for vertical dimension and tooth position. Do not skip the denture scan even if the patient hates the denture. It is the fastest reference the lab has for where the teeth used to live.

Third, photography. Full face at rest, full face smiling, retracted anterior at rest, retracted anterior smiling, lateral profile. Five photos. This is the shade and esthetic reference. Lab technicians designing the tooth setup on a screen cannot see what the patient looks like without them.

Fourth, the prescription. Implant system and diameters, planned occlusal scheme, provisional material, final prosthetic material, shade, and mold preference if the patient has one. Every field filled. "Technician's choice" on a full-arch is how you end up remaking the case.

Fifth, the case planning call. Book it before you ship. Twenty minutes with the technician who will design the guide, walking through the CBCT together. This is the single highest-leverage step in the entire submission and the one most clinicians skip on their first case.

What the lab does with your submission

Once the case lands, a competent full-arch workflow moves through five stages. Understanding the stages is how you know when to expect what.

Stage 1: Digital planning and guide design (3 to 5 business days)

The technician imports the DICOM, aligns it to the intraoral scan, and virtually plans implant positions against the planned tooth setup. This is prosthetically driven placement, meaning the teeth are set first and the implants are placed to support them. If your case planning call happened, this stage moves fast. If it did not, expect a revision cycle that adds three to five days.

The deliverable is a surgical guide, printed and shipped, along with the digital plan for your review.

Stage 2: Provisional fabrication (parallel to surgery)

While you are placing implants, the lab is milling the immediate-load provisional. On a same-day protocol, the provisional is already fabricated to the planned position and needs only pickup at surgery. This works when the guide is fully guided and the surgical protocol holds tolerance. When surgery deviates from plan, the provisional needs chairside modification or a fresh scan and refabrication.

Stage 3: Healing and osseointegration (12 to 16 weeks typical)

Nothing lab-side happens here except the patient care communication. Good labs check in at week 8 and week 14. Great labs already have the final scan appointment on your schedule.

Stage 4: Final impressions and try-in (2 to 3 weeks)

Digital impressions of the healed implants using scan bodies, verification jig for cross-arch accuracy on cases with four or more implants, and a printed try-in for esthetic and phonetic approval. Do not skip the try-in on your first case. Zirconia is not a material you remake casually.

Stage 5: Final prosthetic (3 to 4 weeks)

Monolithic zirconia, titanium bar with individual crowns, or hybrid acrylic depending on the prescription. Milled, characterized, glazed, delivered. The technician's direct line should be on the packing slip in case anything at seat appointment needs clarification.

End to end, a clean case runs 5 to 6 months from surgery to final seat, with the first two weeks being the intake and planning window.

Where first-time submissions break

Three failure modes account for most of the friction on first cases.

The CBCT resolution is too low. Cone beam machines set for endodontic imaging do not capture the field of view needed for full-arch planning. Confirm your machine can capture both arches at diagnostic resolution before you commit the case.

The bite registration is wrong. On edentulous or nearly edentulous patients, the scanner needs a physical bite reference. A wax rim or the existing denture works. Without it, the lab is guessing at vertical dimension and the final prosthetic will need adjustment at seat.

The communication channel is unclear. If your lab hands you a general phone number and a case number, escalations will take days. Get the technician's direct line and email at intake. On a full-arch case, the technician designing the prosthetic is the person you want on the phone at 4pm when a question comes up, not a customer service dispatcher.

What to ask your lab before you commit the first case

Four questions separate the labs that can handle a full-arch workflow from the ones that will learn on your patient.

What is the turnaround SLA on each stage, in business days, in writing? What is the remake rate on full-arch cases in the last twelve months? Who is the technician assigned to my case and how do I reach them directly? What happens if the guide does not seat correctly at surgery?

A lab that answers those four cleanly is a lab that has shipped full-arch before. A lab that hedges on any of them is a lab where your first case becomes their learning case.

The submission checklist

Before the courier pickup: DICOM export, both-arch intraoral scan, bite registration, five clinical photos, existing denture scan if applicable, completed prescription with every field, case planning call booked, technician contact on file. Eight items. Miss one and the case sits at intake.

Full-arch is the highest-stakes prosthetic workflow in general practice. Sending the first case right is a matter of intake discipline and picking the lab that treats the planning call as standard practice, not a courtesy.
