Abstract

Objective: The objective of the present study was to evaluate and compare primary and secondary implant stability of conical endosteal implants placed using osseodensification osteotomy and conventional osteotomy techniques.

Materials and methods: The present invivo study was designed as a prospective, observational study in which a total of 26 endosteal implants were placed in the posterior edentulous regions of upper and lower jaws in 13 patients divided into two groups, Group A and Group B. In Group A, implants were placed using osseodensification osteotomy technique while in Group B, conventional osteotomy technique was used. Primary implant stability was measured in both groups immediately after implant placement while secondary implant stability was measured in both groups at an interval of 4 months. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 20.00 (SPSS Inc., Chicago, IL, USA) while an independent t-test, also, called Student's t-test was used to conduct the analysis.

Results: The mean value of primary implant stability in Group A was found to be 74.5 as against that in Group B which was 62.08 (P-value 0.001). Likewise, the mean value of secondary implant stability in Group A after 4 months' interval was 70.92 while in Group B, it was found to be 63.69 (P-value 0.001).

Conclusions: The dental implants placed with the osseodensification technique showed higher mean primary and secondary implant stability values when compared to implants placed by the conventional technique.

Keywords: Bone-to-implant contact percentage; bone volume percentage; osseodensification; osteotomy; primary implant stability; secondary implant stability.
