“…16 Direct bone-implant contact is reported to be 10% to 58%. 23 With growing versatility in clinical uses of mini-implants, they are remaining inserted for longer periods, including the retention phase, making osseointegration an increasingly important factor in mini-implant stability. 24 Interestingly, N1 required significantly higher force for all displacement distances than DT, although N1 had a smaller surface area than DT.…”

Objective: To compare mechanical stability among five mini-implant designs-a newly invented design and four commercially available designs that vary by shape and threading; to calculate external surface area of each design using high-resolution micro-computed tomography; and to evaluate the relationship between surface area and stability results. Materials and Methods: The four commercially available mini-implants-single-threaded and cylindrical (SC), single-threaded and tapered (ST), double-threaded and cylindrical (DC), doublethreaded and tapered (DT)-and a new implant that is designed to engage mostly in cortical bone with shorter and wider dimensions (N1) were inserted in simulated bone with cortical and trabecular bone layers. The mechanical study consisted of torque measurements and lateral displacement tests. External surface area was computed using a 25-mm micro-CT. Results: Maximum insertion torque, maximum removal torque, and force levels for displacements were the highest in N1, followed by DT, ST, DC, and SC (a 5 .05). The surface area was largest in DT, followed by N1, ST, DC, and SC. Surface area engaged in cortical bone, however, was the greatest in N1. The surface area of mini-implants had positive correlation with stability. Conclusion: Among commercial designs, both added tapering and double threading improved stability. N1 was the most stable design within this research design. The new design has the potential to be clinically superior; it has enhanced stability and there is diminished risk of endangering nearby anatomic structures during placement and orthodontic treatment, but the design requires refinements to reduce insertion torque to avoid clinical difficulty and patient discomfort.

“…To eliminate the dental side effects, titanium miniplates shown to be well tolerated by patients can now be used to apply orthopaedic forces [7]. Titanium TSADs offer direct structural and functional anchorage according to Branemark's definitions [8,9]. The role of TSAD is to provide reliable stability when loaded with forces, without damaging adjacent structures and minimal discomfort to patient.…”

“…It is generally recommended that facemask therapy be started before the age of 8 years [2]. Currently 2 types of TSADs are used: screw implants and bone plates [9]. The zygoma anchorage system introduced by De Clerck et al was used for distalization of the teeth [6].…”

Class III malocclusion is a consequence of maxillary deficiency and/or mandibular prognathism, resulting in an anterior crossbite and a concave profile. Early class III malocclusion treatment with reverse pull headgear generally results in maxillary skeletal protraction but is frequently also accompanied by unfavourable dentoalveolar effects. Titanium miniplates used as temporary anchorage device might permit equivalent favourable skeletal changes without unwanted dentoalveolar effects. We report two cases having class III malocclusion with maxillary deficiency treated by using titanium miniplates. Cephalometric tracings were done pre and post treatment to determine the anatomic changes during the course of treatment.

“…Following these reports, numerous applications of osseointegrated fixtures were demonstrated. 3 Notably, Konomi 4 reported intrusion of anterior teeth using an osseointegrated mini bone screw 1.2 mm in diameter and 6 mm in length. 4 This generated great interest in small microscrews as a source of orthodontic anchorage.…”

Objectives: To evaluate the premise that skeletal anchorage with SAS miniplates are highly successful and predictable for a range of complex orthodontic movements. Materials and Methods: This retrospective cross-sectional analysis consisted of 421 bone plates placed by one clinician in 163 patients (95 female, 68 male, mean age 29.4 years 6 12.02). Simple descriptive statistics were performed for a wide range of malocclusions and desired movements to obtain success, complication, and failure rates. Results: The success rate of skeletal anchorage system miniplates was 98.6%, where approximately 40% of cases experienced mild complications. The most common complication was soft tissue inflammation, which was amenable to focused oral hygiene and antiseptic rinses. Infection occurred in approximately 15% of patients where there was a statistically significant correlation with poor oral hygiene. The most common movements were distalization and intrusion of teeth. More than a third of the cases involved complex movements in more than one plane of space. Conclusions: The success rate of skeletal anchorage system miniplates is high and predictable for a wide range of complex orthodontic movements. (Angle Orthod. 2018;88:27-34.)
