Impacto da osseodensificação na estabilidade primária de implantes. Aplicação em levantamento de seio maxilar em pacientes com densidade óssea comprometida

Abstract

Osseodensification is a bone preparation technique that employs specially designed burs in counter-clockwise rotation, promoting bone compaction and preservation rather than removal. This integrative literature review (2016–2025) evaluated the impact of osseodensification on primary implant stability and its application in maxillary sinus floor elevation in patients with compromised bone density. Thirty-eight studies were analyzed, including randomized clinical trials, systematic reviews, and meta-analyses. The technique resulted in a 30% average increase in peri- implant bone density, an 8.2-point increase in ISQ, and up to 25 Ncm higher insertion torque compared to conventional methods. In transcrestal sinus lift procedures, osseodensification reduced Schneiderian membrane perforation rates from 25% (Summers technique) to 5–10% (p<0.001), with mean bone gain of 3.5 mm and implant survival rates of 98–99% over 5 years. Osseodensification represents a significant advancement in implant dentistry for low-density bone sites, being particularly indicated for transcrestal sinus augmentation and ridge expansion.
