Getting started with ROE’s surgical guides

IMPORTANT CBCT SCANNING TIPS – MUST READ:

Dentate – Always separate the arches with cotton rolls, bite stick or CT equipment bite fork for the scans. NEVER in occlusion! If the patient has MOSTLY metal-based restorations, send models to ROE for scan appliance fabrication!

Mostly Edentulous – If the bite cannot be determined 100%, order bite blocks, a set-up, then a scan appliance.

Fully Edentulous – MUST be in occlusion. DO NOT Separate Arches with anything! Must use a scan appliance – can be the patients’ existing denture(s) with markers, if the fit is excellent, the teeth are close to acceptable position, and NO soft relines.

* Please allow ROE to fabricate scan appliances when they are required. Ideal design, thickness, radiopaque marker position, and size are critical for a successful outcome. The exception would be adding radiopaque markers to an existing denture.

Scan Appliance Full Arch

The Scan Appliance for the fully edentulous patient is a denture, or a clear duplicate of a denture. It is imperative that the fit is excellent and that the teeth are close to an accepted position.

Place 6 SureMarks (www.suremark.com) randomly on the tongue side of the denture, or Gutta Percha dots using a #5 bur 1mm deep.

Scan the appliance in the mouth, fully seated, IN OCCLUSION. Then scan the appliance ALONE in the CBCT scanner sitting on foam or cotton rolls, not on a plastic scan table.
