Por qué importa

Este estudio retrospectivo evalúa la supervivencia de implantes dentales en la mandíbula anterior, un área crítica para la rehabilitación estética y funcional. Los hallazgos indican una tasa de supervivencia acumulada del 90.9% a 11.3 años. Se identificaron la colocación inmediata y la carga inmediata como factores de riesgo para el fracaso, en contraste con la colocación y carga tardías, que actúan como factores protectores. El uso de cirugía asistida por ordenador (S-CAIS) mostró una tendencia a reducir el riesgo de fracaso comparado con la técnica 'freehand'. Estos datos son relevantes para la toma de decisiones clínicas en la planificación y ejecución de tratamientos implantológicos en esta zona, sugiriendo la importancia de considerar el momento de la colocación y carga, así como el apoyo tecnológico en la cirugía.

Abstract original

Objective This study aims to report the implant survival rate of dental implants of partially dentate patients in the anterior mandible and the potential risk indicators for implant failure. Materials and Methods Patients with implant‐supported restorations of single or multiple teeth in the anterior mandible restored with fixed partial implant‐supported restorations were evaluated. Patient demographic data, implant placement timing, and loading protocol, biological and/or technical complications at the time of the last clinical and radiographic follow‐up visit were registered. Survival rate, success rate, and potential risk indicators for implant failure were calculated. Results A total of 108 patients and 186 implants with a mean follow‐up period of 5.48 years (0.1–11.34 years) were included. The 11.3‐year cumulative survival rate was 90.9%. Immediate implant placement (OR = 2.75) ( p = .08) and immediate implant loading (OR = 8.8) ( p = .02*) indicated a higher risk of failure than late implant placement or loading. When combining both categories (type 1A), an OR = 10.59 ( p = .04*) for implant failure was found compared to category 4C. Implants placed following static—computer‐assisted implant surgery (S‐CAIS) showed less risk of failure compared to freehand implant placement (OR = 0.18; 95% CI: 0.02–1.37) ( p = .09). Conclusions The survival rate of implants placed in the anterior mandible was considerably low (90.9%). S‐CAIS, late placement, and conventional loading are protective factor against implant failure in the anterior mandible.
