Objectives
To quantitatively compare stability of dental implants with varying lengths, diameters,
and intraoral locations.
Study Design
Retrospectively, 200 consecutive NobelReplace Tapered Groovy implants of varying lengths
and diameters were evaluated via implant stability quotient readings at placement
(T1) and follow-up (T2). Data were analyzed by analysis of variance and simple linear
regression tests.
Results
Intraoral location was statistically significant at T1 and T2. Although implant diameter
was not statistically significant, implant length resulted in T1 (P = .08) and T2 (P = .09), which may have a clinically relevant effect on implant stability. An overall
implant survival rate of 98% was achieved. Gender and age did not seem to affect implant
stability quotient values at placement, follow-up, or implant survival.
Conclusions
Intraoral location is an important factor in implant stability, with implants placed
in the mandible being more stable than implants placed in the maxilla both at T1 and
T2. Length may have a clinically relevant effect on implant stability.
