INCIDENCE OF DIRECT SINUS LIFT FOR IMPLANT PLACEMENT IN MAXILLARY POSTERIORS

Abstract

Objective: The aim of this study is to evaluate the incidence of direct sinus lift in maxillary posterior region.

Materials and methods: Study samples of 800 cases were obtained from the data of 86000 patients between March 2020 and March 2021. Statistical software used for analysis was the SPSS (statistical package for the social sciences) which is designed by IBM and the statistical tests used were frequency tables along with bar graphs to analyse and compare the obtained results. The obtained data was tabulated in excel systematically. Data was then entered in the SPSS analysis software and descriptive analysis and correlation statistics performed. The obtained results were tabulated and graphically represented.

Results: This study reveals that incidence of direct sinus lift was higher among the male population 57.5% when compared with female population 42.5%; Below 50 years (79.2%) of age patients undergone direct sinus lift during implant placement and Above 50 years of patients are 20.8%; Most of direct sinus lift occurred in the maxillary right molars 43.7%; 32.3% in maxillary left premolars; 9.1% in maxillary right premolars; 14.9% in maxillary left molars.

Conclusion: Further evaluation based on bigger sample size, multi location studies with details on the importance of direct sinus lift could be helpful. The findings of the study showed that direct sinus lift during implant placement is predominantly seen in the male population and the right maxillary molar has a higher incidence of direct sinus lift.
