Por qué importa

Se presenta un estudio prospectivo que evalúa los resultados clínicos a largo plazo de la elevación transalveolar del seno maxilar con instrumentos rotatorios, utilizando la técnica de mínima invasión (MISE), en pacientes edéntulos parcial o totalmente en la zona posterior del maxilar. Se analiza el aumento de hueso vertical y la pérdida ósea marginal, así como la supervivencia de los implantes y la incidencia de complicaciones biológicas y técnicas durante un seguimiento medio de casi 8 años. Los hallazgos sugieren que esta técnica es un protocolo efectivo para la colocación de implantes en casos de reducción ósea alveolar, con tasas de complicaciones por debajo del 10%, lo que resulta relevante para la toma de decisiones clínicas en la rehabilitación de estas zonas complejas.

Abstract original

Background: Transalveolar sinus floor elevation (TSFE) is a surgical technique for the placement of dental implants in patients with reduced height of the maxillary posterior alveolar bone. This study aims to demonstrate the clinical outcomes of TSFE using the minimal invasive sinus elevation (MISE) technique in partially and totally edentulous maxillary patients. Methods: This prospective clinical study followed STROBE guidelines. TSFE was performed using the MISE technique with the simultaneous placement of implants. Dental implants were loaded at 6 months. Maxillary vertical bone gain was measured by CBCT, and marginal bone loss was assessed by periapical radiographs. Results: Ninety-one patients, with a mean age of 62.1 ± 11.8 years, were treated with TSFE and the placement of 107 implants, with a mean follow-up of 96.2 ± 11.7 months. An increase of 4.3 ± 0.4 mm in bone height was achieved, with a dental implant cumulative survival rate of 97.2%. Peri-implantitis was observed in 9.3% of implants, and membrane perforation occurred in 7.7% of cases. Technical complications were noted in 5.5% of patients. Conclusions: Within the limitations of this clinical study, it can be concluded that the MISE technique is a successful protocol for the placement of implants in the posterior maxilla with reduced height of the alveolar ridge, with a rate of biological and prosthetic complications below 10% over an average follow-up period of 8 years.
