Combined orthognathic treatment was effective. Factors affecting treatment duration and percentage reduction in PAR have been established.

Summary Introduction The purpose of this retrospective study was to evaluate 34 years’ experience of autotransplantation of teeth during orthodontic treatment. Methodology Treatment was completed at Queen Mary’s Hospital, Sidcup, Kent, UK, during the period 1969–2003. A total of 366 teeth were transplanted in 314 patients. Results Canines totalled 78 per cent of all autotransplanted teeth; mean age of patient was 19.4 years. Survival probability for the first 5 years post-autotransplantation was 95 per cent, 94 per cent for the subsequent 5 years, and 88 per cent after 15 years. The maximum observation period was 34 years, the median was 2.0 years, and the mean was 3.51 (standard deviation = 3.68) years. Of the observed teeth, 10 failed and these were lost due to unsuccessful periodontal ligament regeneration and persistent mobility grade III (or greater). Apical pathology was observed in 16 per cent of all autotransplanted teeth. In 79 per cent of this subgroup, apical pathology was evident in the first 3 years post-operatively. Seventy per cent of all external resorption also occurred within the first 3 years. Internal resorption was rare but its occurrence was mostly observed between the second and sixth year post-transplantation. A minority of autotransplanted teeth [14 per cent (n = 51)] needed root canal therapy, and this was completed within the first 6 months post-transplantation. Conclusions Autotransplantation can be a justified procedure with good survival probability. It can be considered an alternative to other treatments, such as prosthodontic replacement of teeth.

Pre-operative surgical planning of Le Fort I osteotomies was generally accurate. This study demonstrates that different operators across six centres produced consistent surgical outcomes and this confirms previously reported data.

Background Function, aesthetics, and social and psychological well-being are all important aspects for patients undergoing orthognathic surgery. Objective To evaluate the impact of orthognathic surgery on patient perception and quality of life before, during and after treatment. Search methods All relevant systematic reviews published up to 31st July 2020 have been searched via MEDLINE via OVID, Scopus, EMBASE, Web of Science, Cochrane Database of Systematic Reviews, PsycINFO, AMED (Allied and Complementary Medicine Database), and PubMed. Ongoing systematic reviews and grey literature were eliminated. A manual search was also undertaken, and no restrictions were applied to language or publication date. Selection criteria Systematic reviews involving dentofacial deformities related to systemic disorders, cleft lip and palate, facial trauma, and syndromes affecting cranial and dentofacial structures were excluded. Data collection and analysis Identification, screening, eligibility, and quality assessment [using the AMSTAR 2 tool (A Measurement Tool to Assess Systematic Reviews)] were performed by two authors independently. Data were synthesized qualitatively using thematic analysis. Results A total of 662 eligible studies were obtained of which 24 studies were selected for full-text evaluation, resulting in 12 eligible systematic reviews. Limitations Due to heterogeneity of data, quantitative analysis was not possible. Conclusions and implications Aesthetics and function are the main motives for seeking orthognathic surgery. Patient assessment before, during, and after orthognathic surgery is necessary for a thorough evaluation of self-perception and satisfaction throughout treatment. While psychological and social domains improved after orthognathic surgery treatment, the quality of life can deteriorate transiently during the pre-surgical orthodontic phase of treatment. A standardized assessment tool needs to be developed to assess quality-of-life changes consistently and provide comparable results. Registration CRD42020199091.

Although NCBRS is very rare, it is important to assess dental development in view of the possibility of multiple supernumerary teeth which can have detrimental effects on the occlusion.

The orthodontic treatment of patients on bisphosphonates is becoming an increasing aspect of contemporary practice. This article will draw attention to the chemical structure and effects of these drugs on bone and will provide the latest recommendations to avoid potential sequelae.
