“…The retention portion of the C-implant has a higher osseointegration potential when compared with smooth titanium mini-implants and is better able to resist the rotational tendency during heavy dynamic loads. [19][20][21]33,34 Seo et al, 33 in a study of the histologic and histomorphometric findings of retrieved sandblasted, large grit, acid-etched C-implants that were functionally loaded, showed 52.6% of mean boneimplant contact (%) (excluding the upper smoothsurfaced 2-mm portion of the mini-implant). These authors described the C-implant as a "partially osseointegrated mini-implant."…”

“…22 In contrast, Lee et al showed that SLA surface treatment increased the stability of mini-implants both initially and after osseointegration, allowing various orthodontic forces to be applied. 18 Counterclockwise stability of osseointegrated miniimplants offers the benefit of applying moments one could not apply with smooth-surface mini-implants. This includes such biomechanics as the dynamic forces of intermaxillary elastics and lever arms for incisor intrusion or torque control.…”

“…This demonstrates its resistance to heavy and dynamic forces and rotational moments produced by the intrusive moment of the retraction biomechanics. [15][16][17][18] In spite of a large amount of osseointegration, the coherence would be relatively low, since active remodeling and less mineralized bone formation takes place in the bone around the loaded screw part. 25,26 Also, a guide drill was used to penetrate the cortical bone in this study.…”

“…2,[13][14][15] Reports of an SLA mini-implant have shown good stability and effectiveness when applying rotational moments. [14][15][16][17][18] For example, a clinical method for en masse retraction of anterior teeth without any buccal segment orthodontic appliances was shown to be possible because of this resistance to rotational moments. 16 Although numerous surface modifications have been introduced and used in prosthetic implants, surface-treated orthodontic mini-implants and their resistance to rotational moment have not been widely used or studied.…”

Objective: To test the hypothesis that there is no difference in the stability and resistance to rotational moments of early loaded sandblasted and acid-etched (SLA) mini-implants and those of machined-surface implants of the same size and shape. Materials and Methods: A randomized complete block design was used in 12 skeletally mature male beagle dogs. Ninety-six orthodontic mini-implants were tested. Two types of implants were used: some had SLA surface treatment and some had machined surfaces without coating. After 3 weeks of healing, rotational moments of 150 g were applied. The success rates, maximum torque values, angular momentum, and total energy absorbed by the bone were compared. All values were subjected to mixed-model analysis to evaluate the influence of surface treatment, rotational force direction, and site of implantation. Results:The maximum insertion torque and angular momentum of SLA implants were significantly lower than those of machined implants (P ϭ .034, P ϭ .039). The SLA implants had a significantly higher value for total removal energy than the machined implants (P ϭ .046). However, there were no significant differences in total insertion energy, maximum removal torque, and removal angular momentum between the 2 groups. There was no significant difference between clockwise and counterclockwise rotation in all measurements. Conclusion: SLA mini-implants showed relatively lower insertion torque value and angular momentum and higher total energy during removal than the machined implants, suggesting osseointegration of the SLA mini-implant after insertion.

“…Most of the researchers did not find significant differences between men and women in terms of micro-implant stability [14][15][16][17][18] , which was entirely supported in 2 independent meta-analyses 10,11 evidently proving that sex does not affect micro-implant loosening.…”

The development and introduction of temporary intraoral anchorage devices (TISAD) in the beginning of the 21 st century had a great impact on contemporary orthodontics. The enhancement of the scope of orthodontic treatment, improved efficiency, reduction of both the treatment time and need for the patient's compliance, all of these are the crucial advantages the TISAD have provided to our profession. However, there are also some limiting factors pertaining to this anchorage reinforcement technique which must be borne in mind prior to clinical application. Among some others, premature failure of the micro-implants is the most significant problem related to their utilization, as it entails a repetition of the insertion procedure, increasing the cost and duration of treatment and causing the patient's discomfort. Therefore, recognition of the factors related to the stability of orthodontic micro-implants is necessary for their efficient clinical application and maximum survival rates. Since over the last decade there has been noteworthy progress in the research investigating the issue of micro-implant stability, a review of the most current literature pertaining to this topic was the aim of our article, and ultimately providing clinical recommendations.
