Factors associated with the stability of titanium screws placed in the posterior region for orthodontic anchorage

Patients’ and orthodontists’ perceptions of miniplates used for temporary skeletal anchorage: A prospective study

“…According to Miyawaki et al, 16 prevention of inflammation of the peri-implant tissue is a critical factor for TSAD success rates. Many patients experienced persistent difficulties in cleaning their miniplate anchors.…”

“…As currently designed, miniplates seem to be associated with a lower failure rate than miniscrews. 16 The possibility raised by Liou et al 18 -that miniscrews do not remain stationary under orthodontic forces-suggests that a safety zone for root or nerve proximity might be required. This could further restrict possible placement sites or limit the amount of tooth movement.…”

“…Miniplates, which are placed at a safe distance from the roots, offer the advantages of reduced risk of root impingement, allow the free movement of roots past the TSAD, and are associated with a lower failure rate than miniscrews. 16 Claims have been made that miniplate anchorage simplifies previously complex treatments 19 and permits correction of malocclusions previously thought beyond the scope of orthodontic therapy alone. 20-23 Although appearing to be safer and more stable, and extending treatment possibilities, there are few reports about this type of TSAD, and fewer still of clinician and patient perceptions of their use.…”

“…20-23 Although appearing to be safer and more stable, and extending treatment possibilities, there are few reports about this type of TSAD, and fewer still of clinician and patient perceptions of their use. Most available articles on miniplates are case reports 6,24-32 or retrospectively assessed case series, 16,19,22,33 with only 1 prospective clinical trial 34 reporting adverse events and outcomes during treatment, and only 1 report of patients' opinions and experiences. 16 Also, there is only 1 other study reporting patient perceptions of TSAD use; it addresses palatal implants.…”

Evaluation of changes in trabecular alveolar bone during growth using conventional panoramic radiographs

“…Recently in orthodontics, the focus has been on miniscrew implants as a skeletal anchorage system that does not require patient compliance. Many studies have investigated the factors related to stability because the failure rate of mini-implants, ranging from 9 to 30%, is high compared to that of osseointegrated endosseous implants [7][8][9][10]. Among the factors related to failure, it has been reported that the implantation site has an important role [9,11].…”
