Mini-invasive osteotome sinus floor elevation in partially edentulous atrophic maxilla using reduced length dental implants: Interim results of a prospective study

Research output: Contribution to journalArticle

Abstract

Purpose: The purpose of this prospective study was to investigate the clinical success of a treatment protocol for the rehabilitation of edentulous posterior maxilla consisting of the positioning of short implants in combination with transcrestal sinus lifting, with the adjunct of pure (leukocyte-free) platelet-rich plasma, in order to reducing the risk of membrane perforation and other surgical complications. Materials and Methods: A total of 25 patients (65 implants) were treated. Pure platelet-rich plasma was used in the sinus membrane lifting procedure. Implants of 8.5mm length or shorter were splinted through the prosthetic rehabilitation with one or more implants longer than 10mm. Results: After a follow-up period ranging from 12 to 19 months (mean 14.4 months) after prosthetic loading, 23 patients (60 implants) were evaluated. Overall implant success and survival rates were 100% at 1 year follow-up visit. All prosthetic rehabilitations were successful and in function. After 1 year of loading, peri-implant bone loss averaged 0.34±0.21mm for 8.5mm or shorter implants (n=25) and 0.36±0.30mm for longer implants (n=35) (overall mean 0.35±0.25mm) without significant difference between the two groups (p=0.23). Conclusions: The proposed treatment protocol is a viable option for the rehabilitation of edentulous posterior atrophic maxilla.
