Abstract:
The correlation between implant design and primary stability is a controversial issue. The aim
of this study is to investigate the effect of macro design and mini diameter implants on
primary stability in different bone densities.
Material and method:
An in vitro study for four different implant systems (Camlog, DENTSPLY Friadent, BEGO,
Biomet 3i implants system). Inserted into mandible, scapula and pelvic of porcine bone which
each possess a different bone densities. Followed by primary implant stability measured by
insertion torque, removal torque and resonance frequency analysis. In addition one mini-implant system (3M ESPE) is used with a diameter of 1.8 mm, 2.1 mm and 2.4 mm.
Result:
Result analysis confirmed that there was a significant effect of different implant design on the variables RTV, ITV and ISQ values, (p=0.001), in regards to three bone types (mandible, scapula and pelvis), result analysis confirmed that there was a significant effect on the variables RTV, ITV and ISQ values, (p=0.004). In regards to the Mini-Implant. Significantly positive correlation between ITV and mini implant diameter was observed. Furthermore, RTV was positively correlated with Mini-Implant diameter. Besides that, there were a positive correlation between ITV and RTV (p value 0.01 two tailed).
Conclusion:
In macro and mini diameter dental implants, there is positive correlation among the three
Primary stability parameters of reverse torque, insertion torque and initial stability quotients.
Furthermore, bone type and location influence primary stability of dental implants.
