Restorative Workflow: Lab Scanner

The following workflow details the steps necessary for clinicians to interact with ROE using the Lab Scanner Workflow for a Printed Try-in.

Overview

Patients may change from overdentures to fixed prostheses seeking improved esthetics, function, and self-confidence. The primary considerations are:

  • Highly accurate implant level impressions.

  • Choosing MUA angles and collar heights.

  • Prosthetic space and flange considerations: Many overdenture patients need a flange for lip support, and may be a disqualifier for a fixed prosthesis. A minimum of 13mm of space is required (15mm is ideal) from implant platform to screw exit around the arch.

  • Trying in a prototype in as few appointments as possible.

  • Lab Tech Chairside support for a conversion: A lab tech can help process the All-On-X day of conversion (restorative conversion).

  • The goal of the Overdenture to Fixed Prosthesis workflow is to seat MUAs at the ideal orientation and capture records for a Printed Try-In.

Prerequisites

  • Patient must have existing prosthesis

     

Technology & Materials

  • In-office lab scanner

  • Intraoral scanner

  • Scan analogs

Photographs

  • Full-face full-smile
  • Full-face exaggerated smile
  • Optional: Full-face profile smile

2.

Remove the patient’s prosthesis. Seat the iJIG scan analogs, or approved MUA analogs, passively onto each of the temporary cylinders of the prosthesis.

3.

Perform a 360° scan of the prosthesis in the lab scanner. Remove the scan analogs from the prosthesis.

4.

Scan the tissue and MUAs with your IOS.

5.

Re-seat the prosthesis. Capture the following IOS scans: • Opposing • Bite

6.

Upload all scans to ROE Dental Laboratory.

Next, ROE will fabricate or provide in-office printing files for the Printed Try-In. The Printed Try-In is a 3D-printed prototype of the final prosthesis. See page 58 for more details.
