Optical impression

Intraoral optical impressions are an excellent tool used increasingly in dentistry. Center Médico-Dentaire Balexert offers this cutting-edge technology to its patients.

This type of impression replaces the traditional technique… the optical impression camera eliminates the need to use conventional impression materials (paste put into patients’ mouths).

The optical impression camera is an instrument linked to a scanner that films and records the dental impression, instantly creating a three-dimensional (3D) model on the design software installed on the practitioner’s computer.

Benefits

Optical impressions offer many advantages over conventional impressions:

Increased precision: elimination of manual errors (pulling, bubbling, deformations, etc.)
Simplified production

.

High speed, characterized by less time in the chair
An improvement in patient comfort
An immediate result: visible and immediately correctable defects
Better communication with patient and dental technician
An absence of deterioration (handling, transport, etc.)
Improved workflow (fewer intermediate steps)
Color reproduction: shading of adjacent teeth

.

What's in it for me?

The various indications for optical impressions are as follows:

The fabrication of provisional or definitive crowns/bridges/veneers
The fabrication of inlays/onlays
Implant planning with the possibility of producing surgical guides
Gutter fabrication
Case analysis and orthodontic treatment planning
Design and manufacture of orthodontic appliances (Invisalign®, Clearcorrect®, Incognito®, etc.)

How does it work?

The optical impression is made using an intra-oral camera connected to TRIOS digital image processing software.
After isolation of the area to be recorded (saliva suction/cotton/saliva screens), the camera is inserted into the oral cavity to make the video.

Actually, there are 2 possibilities for proceeding after optical impression recording. Firstly, it is possible to carry out certain procedures “chairside”, meaning that the procedure is completed in a single session/appointment. During this session, the various steps will be carried out: preparation → optical impression → digital modeling → machining → trial → final cementation.

Then, for other procedures, the optical impression is taken first, and after the time needed to plan or make the part has expired, the patient is seen again at a second appointment for explanations or final sealing.
