Effect of Customized Versus Stock Healing Abutments on Peri-Implant Soft Tissue
Esthetic Outcomes and Digital Soft Tissue Assessment of Customized Versus Stock Healing Abutments for Immediate Implants in the Maxillary Esthetic Zone: A Pilot Randomized Controlled Trial
The aim of this study is to compare customized and stock healing abutments for peri-implant soft tissue changes after immediate implant placement in the maxillary esthetic zone, and to assess the feasibility of a full-scale trial.

Description détaillée
Preservation of the peri-implant soft tissue contour and papillae after immediate implant placement is essential for a predictable esthetic result. If customized healing abutments provide better soft tissue outcomes than stock abutments, they could be recommended as a routine step in immediate implant placement in the esthetic zone. Because high-quality comparative evidence is lacking, the present pilot randomized trial was designed to compare the peri-implant soft tissue changes (Pink Esthetic Score at 6 months) around customized versus stock healing abutments, and to provide the feasibility data (recruitment, retention, variability of outcomes) needed to calculate the sample size of a full-scale trial.

Expérimental: Immediate implant placement with a customized healing abutment
A customized healing abutment replicating the emergence profile of the extracted tooth will be fabricated chairside using resin composite on a titanium abutment / digitally designed and milled and connected to the implant at the same surgical visit. Its design will be based on the cervical cross-section of the extracted tooth. |

Comparateur actif: Immediate implant placement with a prefabricated (stock) healing abutment.
• A prefabricated healing abutment will be selected and connected to the implant at the same surgical visit, with the screw torqued according to the manufacturer's instructions. |
