The WES index and implant-supported rehabilitation

Abstract

Introduction: In implant-supported restorations, the good imitation of hard tissues (white aesthetics), symmetry, crown length, color, and texture are crucial for achieving a natural appearance. The White Esthetic Score (WES) allowed for the evaluation of these parameters, scoring each with three categories (2-1-0) by comparison with the adjacent or contralateral tooth; the maximum score of 10 represented complete agreement. Objective: To evaluate the esthetic condition of implant-supported restorations using the White Esthetic Score. Method: A prospective, analytical study was conducted in two stages. The esthetic condition of 270 restorations was evaluated in all patients treated at the "René Otazo Casimajou" Dental Clinic from January 2025 to the present. The study population consisted of 96 patients. Results: Males predominated (58.3%), as did the 35-59 age group. In single-unit restorations, color, at 3.7%, was the dento-prosthetic parameter that showed the greatest variation in the evident difference category compared to the reference teeth. For fixed bridges, the contact area was the most affected parameter, impacting 3.1% of the restorations. 90.4% of the restorations were rated as acceptable. Conclusions: The WES is a tool that allows for the evaluation of the aesthetic conditions of implant-supported restorations. The relationship between the index and the restoration allowed for better treatment planning. An acceptable aesthetic result predominated, with failures being resolved by repeating the restoration to achieve patient acceptance.
