Abstract

Aim | Some studies show that different types of threads in tapered implants result in differences in primary stability. The aim of this study is to perform a prospective, controlled, randomized clinical trial comparing primary and secondary stability between long and standard thread implants for the treatment of partial edentulous patients. Methods | The study sample consists of 23 maxillary partial edentulous patients, in whom 32 implants were placed, with threads of 0.7 mm or 0.3 mm in the premolar and molar location. The comparison, in terms of the implant primary and secondary stability, was 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 and the Mann-Whitney U test. Results | On the day of the implant placement, the 0.7mm thread implants presented greater primary stability in buccal, palatal, mesial and distal compared to implants with 0.3mm threads. The difference was statistically significant. After 3 months, there were no differences between both groups (secondary stability). Conclusion | Despite the limitations of the study, it is possible to verify that the implants with longer threads exhibit greater primary stability on the day of placement.
