The implant loading influence on crestal bone remodelling around hybrid titanium implants: a prospective clinical study

Abstract

The aim of this work was to analyze the changes of the mesial and distal cortical bone peaks around the hybrid titanium implants in relation to the masticatory load up to 7 years of follow-up. The analysis aims how occlusal loads may affect the peri-implant bone years after insertion through two-dimensional analysis using intraoral digital radiographs. Twelve hybrid T3 implants (Biomet 3i) were placed in 9 healthy patients with the 2-stage surgical approach. Standardized digital Rx were taken after early loading (6-8 weeks) after placement (T0); after 12 months (T1); after 30 months (T2); after 4 years follow-up (T3), after 5 years follow-up (T4), after 6 years follow-up (T5), after 7 years follow-up (T6). The marginal bone gain and loss was digitally measured. From T2 to T4 (5 years follow-up) there was a new bone formation demonstrating that well-balanced load forces can ensure good maintenance, with a crestal bone gain during the 2.7 to 7-year follow-up period.
