Facial Scanning for Lip Support Assessment in Full Arch Implant Rehabilitations

Study Overview
=================
Brief Summary
-----------------
Lip support plays an important role in facial esthetics, being a relevant factor when realizing full arch implant supported rehabilitations. However, there is a lack of research on the three dimensional impact of such restorations.

Detailed Description
-----------------
As lip support is becoming more determinant in the facial esthetics outcome after full arch implant rehabilitation, there is a need to know the influence of said rehabilitation in the lower third profile of the patients. Then, through facial scanning, this study's purpose is to evaluate three dimensional changes that arise since the initial state that the patient presents to the office until is rehabilitated through 3D discrepancies and 2D linear measurements.

Design Details

Primary Purpose: Diagnostic
Intervention Model: Single Group Assignment
Interventional Model Description: Patients will be quantifiably evaluated regarding facial esthetics and compared before and after the full arch implant supported rehabilitation.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Rehabilitated<br>Initial lip support condition of the patient when presents himself/herself at the office with indication for full arch implant rehabilitation. Then, the patient is facially scanned before and after the implant surgery. | Device: Facial scanner<br>* The Bellus3D facial scanner will be used to scan the patient before and after implant rehabilitation in order to produce .obj files that allow 3D comparisons and to obtain discrepancy values regarding lip support.<br>|
