Early treatment has definite benefits for growing patients and Class III patients in particular if only to allow a normal growth pattern to be restored giving the patient a chance to escape surgery and allowing better esthetics at a younger age .Ten growing Class III patients were treated using the Class III splint appliance until the anterior cross bite was transformed into a positive over jet. Pre and post treatment cephalometric radiographs were taken, then skeletal, dental and soft tissue measurements were done. Pre and post treatment measurements were compared to assess profile changes using the paired t-test.Definite improvement was seen clinically in all the cases, and proved statistically to be due to both dental and skeletal effects in the form of upper incisor proclination and lower incisor retroclination, a significant increase in the SNA angle with concomitant decrease in the SNB angle.The soft tissue profile was restored to a more normal profile through a decrease of lower lip thickness and an increase in its length.

The last decade (2010-2021) has witnessed the evolution of robotic applications in orthodontics. This review scopes and analyzes published orthodontic literature in eight different domains: (1) robotic dental assistants; (2) robotics in diagnosis and simulation of orthodontic problems; (3) robotics in orthodontic patient education, teaching, and training; (4) wire bending and customized appliance robotics; (5) nanorobots/microrobots for acceleration of tooth movement and for remote monitoring; (6) robotics in maxillofacial surgeries and implant placement; (7) automated aligner production robotics; and (8) TMD rehabilitative robotics. A total of 1,150 records were searched, of which 124 potentially relevant articles were retrieved in full. 87 studies met the selection criteria following screening and were included in the scoping review. The review found that studies pertaining to arch wire bending and customized appliance robots, simulative robots for diagnosis, and surgical robots have been important areas of research in the last decade (32%, 22%, and 16%). Rehabilitative robots and nanorobots are quite promising and have been considerably reported in the orthodontic literature (13%, 9%). On the other hand, assistive robots, automated aligner production robots, and patient robots need more scientific data to be gathered in the future (1%, 1%, and 6%). Technological readiness of different robotic applications in orthodontics was further assessed. The presented eight domains of robotic technologies were assigned to an estimated technological readiness level according to the information given in the publications. Wire bending robots, TMD robots, nanorobots, and aligner production robots have reached the highest levels of technological readiness: 9; diagnostic robots and patient robots reached level 7, whereas surgical robots and assistive robots reached lower levels of readiness: 4 and 3, respectively.
