Abstract
The objective was to evaluate the influence of residual bone height (RBH) and implant macro -design on the primary stability (PS) of implants using a simultaneous sinus floor elevation (SFE) and implant insertion model. Fresh bovine rib samples that resembled type -IV density that were confirmed by computerized tomography were prepared to represent 4 groups of varying RBHs (3, 6, 9, 15 mm). To simulate simultaneous implant insertion with SFE, 120 implants in different macro -designs (group R: NobelReplace; group P: NobelParallel; group A: NobelActive, Nobel Biocare, Gothenburg, Sweden) were randomly inserted at RBHs of 3, 6, 9, and 15 mm in each rib. The implant stability quotient (ISQ) was measured immediately after implant insertion. RBH and implant macro -design have an impact on ISQ values (P < .001). ISQ values were the highest with RBH of 15 mm, followed by RBHs of 9, 6, and 3 mm. (P < .001). There was no statistically significant difference between different implant macro -designs at RBHs of 3 and 15 mm regarding ISQ values (P = .111, P = .551). ISQ values of group P were higher than those of group R and group A at an RBH of 6 mm (P = .049, P = .029). ISQ values were also higher in group P compared to group A at an RBH of 9 mm (P = .006). A higher PS may be expected in sites with higher RBH, regardless of the macro -design. In addition, cylindric implant design may enhance the PS at RBHs of 6 and 9 mm in simultaneous implant insertion with SFE.
