# Three-dimensional Assessment of Facial Alterations Induced by Dental Prostheses

**Official Title:** Analysis of Three-dimensional Modifications Caused by Full Arch Implant Supported Dental Prosthesis With a Facial Scanner

**NCT ID:** [NCT04050878](https://clinicaltrials.gov/study/NCT04050878)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 20
- **Lead Sponsor:** Implantology Institute
- **Collaborators:** Grupo de Investigação em Bioquímica e Biologia Oral
- **Conditions:** Soft Tissue
- **Start Date:** 2020-06-01
- **Completion Date:** 2020-06-21
- **CT.gov Last Update:** 2020-06-30

## Brief Summary

Validation of the use of a facial scanner for assessment of modifications caused by the use of dental prostheses and determination of discrepancies related to conventional measurements with digital caliper.

## Detailed Description

3 dimensional evaluation of lip support by the use of full arch impplant supported rehabilitations with the use of a facial scannner. Determination of discrepacies between the obtained facial scan and conventional measurements made by a digital caliper on the face.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL
- **Healthy Volunteers:** Yes

```
Inclusion Criteria:

* Patients rehabilitated with full implant supported upper dental prostheses.

Exclusion Criteria:

* Patients without beard, facial deformities, earrings or braces.
```

## Arms

- **Patient with or without dental prostheses** (EXPERIMENTAL) — The patient will be submitted to two facial scans, one with and another without the dental prostheses and the obtained datasets will be compared to assess the differences. Marks will be made in the face to allow for measurements (digital and conventional)

## Interventions

- **Facial scanner (Bellus3D) to assess perioral alterations** (DEVICE) — Use of a digital caliper for conventional measurements and a facial scanner (Bellus3D) to analyse the modifications induced by the use of implant supported dental prostheses in the lip support

## Primary Outcomes

- **Soft tissue changes in µm with and without implant supported dental prostheses** _(time frame: Both scanning procedures will be made in the same appointment upon 3 months use of delivery of the final implant supported full dental prostheses)_ — Differences in the perioral soft tissues with and without dental prostheses in µm
