Abstract

Objective To clarify whether implant macrodesign has any influence on primary stability. Implant primary stability was evaluated in different substrates (fresh cow ribs and polyurethane artificial bone blocks) using several methods. Materials and Methods A total of 36 titanium dental implants (3.5 mm × 10 mm) and then divided into 3 groups (n=12): implants have trapezoidal thread design, implants have buttress thread design and implants have reverse buttress thread design were inserted in two different substrates (six fresh cow ribs and eighteen polyurethane casts). Immediately after insertion of dental implant, the implant stability was measured using three different methods (insertion torque, Periotest and AnyCheck device). Results The results of insertion torque, Periotest and AnyCheck device showed that the dental implants with trapezoidal thread design exhibited the highest primary stability in both cow rib and polyurethane substrates. In contrast, the results showed that the dental implants with a buttress thread design, showed the lowest primary stability in both cow rib and polyurethane substrates. Also, there was a significant difference in primary stability between the two substrates. Primary stability was consistently greater with polyurethane casts than with cow ribs. The results showed a significant interaction between implant design and substrate type, suggesting that the efficacy of each implant design differed according to the substrate. Conclusions Implant macrodesign has marked effect on primary stability in different substrates, which is essential prerequisite for osseointegration.
