“…In the oral cavity, the palate is a popular sitefor TAD placement because of the thick keratinized masticatory mucosa, high accessibility, and reduced risk of root damage 6. Recently, several investigators have examined the adjacent areas of the midpalatal suture for use in TAD-assisted distalization mechanics in adolescents and adults 7,8…”

ObjectiveThe purposes of this study were to measure the palatal soft tissue thickness at popular placement sites of temporary anchorage devices (TADs) by cone-beam computed tomography (CBCT) and evaluate the age, gender, and positional differences in this parameter.MethodsThe study sample consisted of 23 children (10 boys and 13 girls; mean age, 10.87 ± 1.24 years; range, 6.7 to 12.6 years) and 27 adults (14 men and 13 women; mean age, 21.35 ± 1.14 years; range, 20.0 to 23.8 years). Nine mediolateral and nine anteroposterior intersecting reference lines were drawn on CBCT scans of the 50 subjects, and the resultant measurement areas were designated according to their mediolateral (i.e., lateral, medial, and sutural) and anteroposterior (i.e., anterior, middle, and posterior) positions. Repeated-measures analysis of variance was performed to analyze intragroup and intergroup differences.ResultsNo significant age and gender differences were found (p = 0.309 and 0.124, respectively). Further, no significant anteroposterior change was observed (p = 0.350). However, the lateral area presented the thickest soft tissue whereas the sutural area had the thinnest soft tissue (p < 0.001).ConclusionsClinical selection of the placement sites of TADs should be guided by knowledge of the positional variations in the palatal soft tissue thickness in addition to other contributing factors of TAD stability.

“…Miniscrews have enabled numerous orthodontic treatments that were difficult with conventional appliances: eg, mesial movement of a molar in a patient with oligodontia, 3 distal movement of the maxillary and mandibular teeth, 4 and improvement of an open bite caused by intruding posterior teeth. 5 In addition, miniscrews have often been used to provide 2-dimensional absolute anchorage during edgewise treatment.…”

“…Mini-implants have grown in popularity as an important tool to facilitate maximum anchorage without the use of extra-oral appliances. [1][2][3][4] As a result, patient compliance has become less crucial in treatment predictability. If placed properly, mini-implants can provide the patient with a more esthetic, convenient, and comfortable experience.…”

; Won Moon a ABSTRACT Objective: To assess the mechanical stability of a newly revised orthodontic mini-implant design (N2) compared with a design introduced in Part 1 of the study (N1) and the most widely-used commercially-available design (CA). To evaluate the mean buccal bone thickness of maxillary and mandibular posterior teeth using cone-beam computed tomography (CBCT). Materials and Methods: From the CBCT scans of 20 patients, six tomographic cross-sections were generated for each tooth. Buccal bone thickness was measured from the most convex point on the bone to the root surface. CA (1.5 mm in diameter and 6 mm in length), N1, and N2 (shorter and narrower than N1) were inserted in simulated bone with cortical and trabecular bone layers. Mechanical stability was compared in vitro through torque and lateral displacement tests. Results: The bone thickness ranged from 2.26 to 3.88 mm. Maximum insertion torque was decreased significantly in N2 compared to N1. However, force levels for all displacement distances and torque ratio were the highest in N2, followed by N1 and CA (a 5 .05). Conclusions: Both torque and lateral displacement tests highlighted the enhanced stability of N2 compared with CA. Design revisions to N1 effectively mitigated N1's high insertion torque and thus potentially reduced microdamage to the surrounding bone. The N2 design is promising as evidenced by enhanced stability and high mechanical efficiency. Moreover, N2 is not limited to placement in interradicular spaces and has the capacity to be placed in the buccal bone superficial to the root surface with diminished risk of endangering nearby anatomic structures during placement and treatment.
