Summary

Some studies show that different types of threads in tapered implants result in differences in primary stability. The aim of this study is to a perform a prospective, controlled, randomized clinical trial comparing primary and secondary stability between long and standard thread implants in the treatment of partial edentulous patients.

Detailed description

The study sample consists of 23 maxillary partial edentulous patients, where 32 implants were placed, with threads of 0.7 mm or 0.3 mm in the location of premolars and molars. The comparison, in terms of primary stability, is made by measuring the ISQ value (implant stability quotient), in four locations (buccal, palatal, mesial and distal). Statistical analysis was performed using the independent T-Test.
