Abstract:
This study evaluates the influence of different implant materials on the primary stability of orthodontic mini‐implants by measuring the resonance frequency. Twenty‐five orthodontic mini‐implants with a diameter of 2 mm were used. The first group contained stainless steel mini‐implants with two different lengths (10 and 12 mm). The second group included titanium alloy mini‐implants with two different lengths (10 and 12 mm) and stainless steel mini‐implants 10 mm in length. The mini‐implants were inserted into artificial bones with a 2‐mm‐thick cortical layer and 40 or 20 lb/ft 3 trabecular bone density at insertion depths of 2, 4, and 6 mm. The resonance frequency of the mini‐implants in the artificial bone was detected with the Implomates ® device. Data were analyzed by two‐way analysis of variance followed by the Tukey honestly significant difference test (α = 0.05). Greater insertion depth resulted in higher resonance frequency, whereas longer mini‐implants showed lower resonance frequency values. However, resonance frequency was not influenced by the implant materials titanium alloy or stainless steel. Therefore, the primary stability of a mini‐implant is influenced by insertion depth and not by implant material. Insertion depth is extremely important for primary implant stability and is critical for treatment success.
