Abstract

Aim: To undertake a systematic review for the association between the initial alveolar bone height and the success of dental implants with sinus elevation procedures. Materials and Methods: An online search was performed using the following electronic databases: PubMed, Medline, Science Direct, and Blackwell synergy. Two investigators independently assessed publications for inclusion and extracted data. Meta-regression analyses were used to test the associations between the initial alveolar bone height and implant survival with lateral window or osteotome sinus elevation procedures. Results: Of 635 studies, 21 were included for analysis. A quadratic curve-fitting meta-regression showed an increasing trend of implant survival rate with greater initial bone height for the lateral window technique (p2=0.97). The result of the meta-regression for hazard rates showed a decreasing trend (p=0.0041, adjusted R2=0.89). No association was found for the osteotome technique. Conclusions: For the lateral window technique, meta-regression analysis suggested a positive association between the initial alveolar bone height and implant survival rates. No relationship was found between the initial alveolar bone height and implant survival rate for the osteotome technique due to a lack of data below 4 mm of initial bone height.
