“…[25][26][27][28][29] Miniplates have been shown to be well accepted as skeletal anchorage by both patients and providers and have turned out to be a safe and effective adjunct for complex orthodontic treatment. 24 However, the success rate of miniplates for skeletal anchorage in orthodontics [30][31][32][33] has not been investigated so thoroughly as that of miniscrews, and research has been limited to adolescent and adult patients. Compared with miniscrews and microscrews, miniplates showed greater stability.…”

“…Compared with miniscrews and microscrews, miniplates showed greater stability. 31 However, only the effect of continuous loading on miniplate stability has been investigated. The forces generated by intermaxillary elastics are discontinuous in time, magnitude, and direction because of movements of the mandible during speech, chewing, and swallowing.…”

Objective: To evaluate the success rate of Bollard miniplate anchorage for bone anchored maxillary protraction (BAMP). Materials and Methods: Twenty-five consecutive patients (mean age, 12.0 6 1.2 years; range, 8.7-14.8 years) with maxillary hypoplasia without congenital or acquired deformation were included in this study. A total of 100 Bollard modified miniplates were placed by the same surgeon. Ninety-nine miniplates were inserted under general anesthesia, and one was placed under local anesthesia because of initially soft bone conditions. Loading of the miniplates with 150 g elastics was initiated at 17.5 6 6.9 days (range, 11-38 days) after surgery. Mean follow-up was provided at 20.8 6 11.1 months (range, 6.5-46.2 months). Results: The overall success rate of miniplate anchorage in terms of stability was 97%. During orthodontic loading, five miniplates showed signs of mobility. After interruption of loading over 2 months, two miniplates became stable again. However, a total of three miniplates needed to be removed and were successfully replaced under local anesthesia after a mean healing period of 3 months. Conclusion: Skeletal anchorage by means of Bollard modified miniplates is effective for BAMP. Success depends on proper presurgical patient counseling, minimal invasive surgery, good postsurgical instructions, and orthodontic follow-up. (Angle Orthod. 2011;81:1010-1013

“…After the introduction of MIs to orthodontic practice, several studies investigated MI success rates and factors associated with MI failure (1,(5)(6)(7)(8)(9)(10). However, previous studies did not consistently define these outcomes, which complicate subsequent follow-up studies of MI success and failure rates.…”

“…The advantages of TADs, as compared with conventional anchorage devices, include easier manipulation, simpler treatment mechanics, shorter total treatment time, and greater patient comfort during orthodontic treatment (1). Additionally, treatment outcome does not depend on patient compliance, and anchorage loss is not a concern.…”

“…Consequently, the density and architecture of the trabecular host bone are crucial to the stability of an endosseous implant in the alveolar ridge. Regarding mini-implants, younger patients seem to exhibit a greater risk of failing compared to adult patients [13].…”

Objective. To assess changes of the alveolar trabecular bone during growth using panoramic radiographs and to detect possible differences in trabecular bone patterns when comparing individuals of various ages and genders. Materials and methods. Conventional panoramic radiographs of 18 young (eight females, 10 males) and 21 adult (12 females, nine males) subjects were taken at 2 years (T1) and 10 years (T2) after the end of orthodontic treatment. At T1, mean ages were 15.6 ± 0.9 years and 31.3 ± 9.7 years in the young and the adult groups, respectively. A three-scale visual analysis was used to evaluate bilaterally the alveolar bone trabeculation in the interdental spaces, from the distal side of the first mandibular premolar to the mesial side of the second lower molar. An analysis of variance (ANOVA), associated with t-tests whenever significance was found, was used to appraise the role of the age, the extent of the follow-up period and the gender on trabecular bone structure. Results. The adult group had a denser alveolar bone trabeculation, compared to the young group. This was also observed in the 8 years followup recordings among the adults, but no statistically significant differences were found in the growing individuals. No gender discrepancy was detected. Conclusions. From puberty to the middle age adulthood, denser alveolar bone trabeculation in the mandible seems to be related to the age. No differences were found between male and female subjects in the sample.
