Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study design is a prospective, multi-center randomized, controlled, open label, 3-arm parallel group, post market clinical follow-up (PMCF) Clinical Trial.

The aim of the study is to collect clinical performance and safety data from RACEGEL and RACESTYPTINE Solution. Three gingival retraction techniques are being studied: RACESTYPTINE Solution with cord, RACEGEL with cord and RACEGEL without cord.

The study will demonstrate the expected performance of these 3 techniques in terms of sulcus opening, i.e. a lateral gingival displacement of at least 200 µm (state of the art) allowing the realization of pre-prosthetic impression with subgingivally margins. 90 subjects (teeth) requiring a dental restoration with subgingival margins for placement of a fixed prosthesis will be enrolled in 3 groups (30 in each group). For each participant, two dental impressions are performed: one impression before the gingival retraction and one impression immediately after the gingival retraction. Both impressions are scanned with 3D dental scanner and images are superimposed before analysis of tissue displacement.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Study subject (tooth) will be randomized in a 1:1:1 allocation ratio between the 3 gingival retraction techniques.
Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors
Blinding will be done to the assessors who analyzed dental impression to reduce bias to gingival tissue displacement assessment

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

RACESTYPTINE Solution with cord

The participant will receive RACESTYPTINE Solution into the sulcus. The solution is used in combination with a non-medicated gingival retraction cord.

Group Type EXPERIMENTAL

RACESTYPTINE Solution with cord

Intervention Type DEVICE

The dentist inserts a non-medicated gingival retraction cord into the sulcus and then impregnates the cord in situ with a few drops of RACESTYPTINE Solution. The impregnated cord is left in place a few minutes and then removed. The gingival sulcus is washed and gently air-dried before taking impression.

RACEGEL with cord

The participant will receive RACEGEL into the sulcus. The gel is used in combination with a non-medicated gingival retraction cord.

Group Type EXPERIMENTAL

RACEGEL with cord

Intervention Type DEVICE

The dentist applies a sufficient amount of RACEGEL directly into the sulcus, following the contour of the prepared tooth, and then inserts a non-medicated gingival retraction cord into the sulcus. The impregnated cord is left in place a few minutes and then removed. The sulcus is washed and gently air-dried before taking impression.

RACEGEL without cord

The participant will receive RACEGEL into the sulcus. No cord will be added.

Group Type EXPERIMENTAL

RACEGEL without cord

Intervention Type DEVICE

The dentist applies a sufficient amount of RACEGEL directly into the sulcus, following the contour of the prepared tooth. The gel is left in place a few minutes and then removed. The sulcus is washed and gently air-dried before taking impression.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adult male or female (age ≥18 years),
* Patient requiring a dental restoration with subgingival margins on one or more teeth with placement of a single or multiple fixed prosthesis. Partially edentulous patients can be enrolled.
* Good oral hygiene
* Healthy periodontium and gingiva: probing depth ≤3 mm, no evidence of gingival inflammation (gingival index ≤ 1), attachment loss (attached gingival \>2 mm), bleeding on probing, or plaque accumulation (plaque index \< 3)
* Patient who received information and gave written consent.
* Patient affiliated with a social security/protection plan.

Exclusion Criteria

* Contraindication to taking impression evidenced at the latest on the day of inclusion visit (gingival index ≥2, sign of attachment loss or tooth mobility, probing depth \>3 mm).
* Known allergy to aluminum, aluminum salts or to one of the compounds of the formula of the gingival retraction material, or to one of the compounds of the impression material.
* Patient with an unbalanced systemic disease (diabetes, thyroid disorders, history of oropharyngeal cancer),
* Simultaneous participation in another interventional clinical investigation or trial,
* Vulnerable Subjects
