Por qué importa

Este estudio compara la generación de calor durante la osteotomía para la colocación de implantes dentales utilizando un protocolo convencional de perforación secuencial frente a un protocolo de perforación única en cirugía guiada digital. La relevancia clínica radica en optimizar el procedimiento quirúrgico para minimizar el estrés térmico en el hueso, un factor crítico para la supervivencia del implante. Los hallazgos indican que, si bien la elevación de temperatura es similar entre ambos métodos, el protocolo de perforación única reduce significativamente el tiempo de exposición, lo cual podría traducirse en mayor eficiencia y menor riesgo de necrosis ósea. Se valida además la comparabilidad de los resultados obtenidos en modelos ex vivo (costilla bovina) con los de modelos in vivo (tibia de conejo).

Abstract original

PURPOSE: To compare heat generation during osteotomy for dental implant placement using a conventional (sequential drilling) drill protocol versus a single-drill protocol in digitally guided surgery and to clarify differences in thermal exposure time. MATERIALS AND METHODS: In this study, we used a bovine rib ex vivo model with a surgical splint and a type K thermocouple to measure temperature and time. The conventional protocol (n = 20) involved sequential drilling using six drills of increasing diameter, while the simplified protocol used a single drill (n = 20). Four implant beds were prepared in the tibia of a New Zealand rabbit to compare the mean temperature values between the in vivo and ex vivo models. RESULTS: Student's t-test revealed no significant differences (P = .1688) in temperature elevation between the conventional (mean = 1.977°C; SD = 1.165) and single-drill (mean = 2.634°C; SD = 1.734) protocols. However, significant differences between the groups were found in the exposure time: conventional drilling protocol-107.105 seconds (SD = 29.196); single-drill protocol-16.842 seconds (SD = 8.101). The mean temperature increases due to drilling were 0.365°C (SD = 0.204) and 0.378°C (SD = 0.381) in the rabbit tibia and bovine rib, respectively; however, no significant differences (P = .926) were found between the in vivo and ex vivo models. CONCLUSIONS: Conventional and single-drill guided surgery protocols for implant bed preparation generate similar temperatures in vitro. Exposure time is longer with conventional protocols than with single-drill protocols.
