“…The stability of mini‐implants is influenced by mechanical retention and biological reactions. Primary stability is a mechanical phenomenon related to bone quality and quantity, mini‐implant geometry, and placement technique [20]. Secondary stability is a consequence of bone modeling and remodeling at the implant–bone interface [21].…”

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.

“…Resonance frequency analysis (RFA) is a noninvasive method of measuring dental implant stability in vivo, a value used to calculate an implant stability quotient (ISQ) which ranges between 0 and 100 (measured between 3500 and 8500 Hz). Estimates of implant stability using resonance frequency analysis are highly correlated with maximum insertion torque (Suzuki et al 2010). Numerous in vitro and in vivo studies have confirmed RFA as a technique designed to reflect the bone-implant interface (Meredith et al 1996;Meredith 1998;Zix et al 2008).…”

Survival rate of short implants after 90 days was lower than that of regular implants. However, short implants may be considered a reasonable alternative for rehabilitation of severely resorbed mandibles with reduced height, to avoid performing bone reconstruction before implant placement. Patients need to be aware of the reduced survival rate compared with regular implants before implant placement to avoid disappointments.

“…1 Secondary stability is a consequence of bone modeling and remodeling at the OMI-bone interface. 1,2 Although high insertion torque can increase primary stability, 3 it might have a negative effect on secondary stability due to the excessive compression stress, microdamage, and peri-implant bone resorption. 4,5 Therefore, Motoyoshi et al 6,7 and Suzuki and Suzuki 8 insisted that it is necessary to bring the insertion torque into a proper range that can satisfy the primary and secondary stability of OMIs simultaneously.…”

Objective: To investigate the effects of orthodontic mini-implant (OMI) shape and predrilling depth on the mechanical properties of OMIs during the insertion procedure. Materials and Methods: A total of 30 OMIs (self-drilling type, 7 mm in length; Biomaterials Korea Inc) were allocated into six groups according to OMI shape (cylindrical and tapered type) and predrilling depth (control, 1.5-mm and 3.0-mm predrilling; predrilled with a drill-bit [1 mm in diameter]): C-con, C-1.5, C-3.0, T-con, T-1.5, and T-3.0 groups (N 5 5 per group). The OMIs were installed in artificial bone blocks with two layers that simulated the cortical and cancellous bone (SawboneH, Pacific Research Laboratories Inc). Total insertion time (TIT), maximum insertion torque (MIT), total insertion energy (TIE), and inclination of the time-torque graph (INC) were measured. Results: Within the same shape group, although predrilling groups exhibited shorter TIT than control groups (control vs 1.5; control vs 3.0; all P , .05), there was no difference in TIT between 1.5-mm and 3.0-mm predrilling groups. MIT and TIE decreased in the order of control, 1.5-mm predrilling, and 3.0-mm predrilling (control vs 1.5; 1.5 vs 3.0; all P , .05), but INC revealed a pattern of increase from control to 1.5-mm predrilling and of decrease from 1.5-mm predrilling to 3.0-mm predrilling within the same shape group (control vs 1.5, 1.5 vs 3.0, all P , .05). The MIT and INC of C-con were smaller and less steep than those of T-con (P , .01 and P , .05, respectively). In the same predrilling depth, no differences were observed in MIT, INC, and TIE between cylindrical and tapered groups. Conclusion: In cases of thick cortical bone, predrilling might be an effective tool for reducing microdamage without compromising OMI stability. (Angle Orthod. 2012;82:618-624.)
