Abstract
BACKGROUND: This study aimed to compare insertion torque (IT) and implant stability quotient (ISQ) values immediately and three months after surgery with standard drilling (SD) and osseodensification (OD) drilling methods. METHODS: In this prospective study, 39 implants with the same diameter and length were placed in 21 patients using SD (23 implants) and OD (16 implants) methods in the posterior maxilla. The amounts of IT after surgery and ISQ after surgery and three months later were evaluated. The data were extracted and statistically analyzed with PASS2 software. The difference between IT and ISQ was determined by the two-way repeated-measures ANOVA at a significance level of 0.001. RESULTS: Immediately after surgery, the amount of IT using the OD drilling method was 37% higher than the SD drilling (P<0.001). ISQ values after surgery did not show a significant difference between SD and OD (P1<0.176). Three months after surgery, the ISQ values in both groups were not significantly different. ISQ values for all OD and SD group experimental parameters remained above the threshold value of 68. IT values showed a positive correlation with ISQ values at baseline. CONCLUSION: In the present study, the OD technique provided a higher IT rate after surgery compared to the SD method; however, no difference was seen between the two groups regarding ISQ value either after surgery or three months later.
