Background: orthodontic mini implants are widely used nowadays in orthodontic practices. It is made up of various materials, due to its advantage of greater anchorage control and better patient compliance they play a pivotal role in orthodontic treatments. Primary stability of these mini implants at different angulations are tested in this study.
Aim & Objective: Aim of the present study is to evaluate and compare the primary stability of self-drilling orthodontic titanium mini-implants (JJ Orthodontics) inserted in polyurethane bone blocks at different insertion angles using a pull-out test.
Materials and Methods: A total of 24 newly purchased (1.6 x 8 mm) orthodontic titanium mini-implants were obtained and inserted in polyurethane foam bone blocks simulating cortical and cancellous bone layers having density of 50 PCF and 40 PCF respectively with help of implant driver manually. Each specimen was tested for pull-out strength using the Universal Testing Machine with a loading speed of 1 mm/min.
Results: The mean distribution of Pull out Strength for JJ orthodontics inserted in polyurethane bone block at 900 and 600 was 98.50 ± 12.10 and 141.19 ± 12.92 respectively. A high statistically significant difference was observed in pull out strength at 600 and 900 angle (P<0.001).
Conclusion: As the result concludes the pull-out strength at 600 is greater than 900, which states insertion angle plays an vital role in the primary stability of the mini implant.
