Abstract
Backgrounds: Dental implants are regarded as treatment for patients who are completely or partially edentulous, thus, a s??g??????????t requirement for osteointegration is implant stability. Objectives: The aim of this study was to compare primary and secondary stability measured by Implant Stability Test (IST®) between different bone types and to compare implant stability at different time points during 3 months of follow-up. Material and Methods: A total of 40 implants were placed in 16 patients (9 males and 7 females with a range of 22-61 years (mean age 40.44 ± 12.3 years). Bone quality was evaluated according to Lekholm and Zarb index during drilling procedure. After inserting the implant, stability was measured by implant stability test IST immediately, and after 3 months. Results: A statistically s??g??????????t correlations were found between primary and secondary stability using implant stability test IST® among different bone types. Conclusions: The primary stability lead to more ef????????et secondary stability achievement with different bone quality, and the CBCT technique is an ef????????et method for bone quality types assessment, and s??g??????????t???? correlated with implant stability parameters and Lekholm and Zarb index
