An assessment of the long-term results of a series of first and second premolar extractions. First premolar extractions produced a higher proportion of satisfactory upper contacts and buccal occlusions, but second premolar extractions, were more often associated with space closure. Approximately 40 per cent of lower contacts were unsatisfactory. There was little difference between the premolars in this or with regard to residual lower incisor crowding. No association between the presence of third molars and space closure was found.

Reducing the orthodontic treatment duration is an important issue, especially for adult patients who want to complete treatment faster due to social or aesthetic reasons. In addition, an increase in the duration of orthodontic treatment has a number of side effects, therefore, orthodontists and patients are interested in the use of techniques that can accelerate the movement of teeth. Shorter treatment times can be achieved through a combination of orthodontic and surgical or non-surgical techniques.Aim. To systematically evaluate scientific data on the effectiveness and side effects of surgical and non-surgical methods in accelerating orthodontic treatment in situations with the removal of premolars and subsequent closure of the post-extraction spaces.Materials and methods. Electronic search of articles was carried out using search engines and databases: Cyberleninka, eLIBRARY, Google Scholar, Pub Med, SCOPUS. The publication date criterion was selected from January 2010 to January 2021. Articles included in the systematic review had to meet the following inclusion criteria: controlled clinical trials and randomized controlled clinical trials conducted in humans and published in the last 11 years in English language. The systematic review included and analyzed 15 full-text articles.Result. According to the systematic review, the speed of movement of teeth increases 2 times with corticotomy, and 1.5 times with piezocorticotomy, which is consistent with the data of other studies. At the same time, the effectiveness of the movement remains for no more than 2 months after the intervention.Conclusions. The corticotomy procedure reduces the treatment time in comparison with traditional methods by 30-50% (6-8 months). The investigated techniques did not have a significant effect on the depth of probing, the level of attachment, on the density of bone tissue, rotation and inclination of the moved teeth. Since no complications were identified for 2-4 months of observation, further studies are required to assess long-term results in the long term.

Objective To analyze the long-term effect of mandibular bone as donor material in bone grafting of the alveolar process defect in patients with unilateral cleft lip and palate (UCLP), compared with iliac crest cancellous bone. Method During a 7-year period, 101 UCLP patients were bone grafted, 57 cases with iliac crest cancellous bone and 44 with mandibular symphyseal bone. The long-term results with an observation time of more than 4 years were analyzed with respect to marginal bone level and dental and gingival condition in the grafted area. Complications were recorded. Results The bone level in the grafted area was satisfactory in both groups. Impaction of cleft-side canines was found in 35% of the patients in both groups. Patients with agenesis of the cleft side lateral incisor had significantly more impacted canines, compared with patients with a cleft-side lateral situated in the lesser maxillary segment, probably due to the fact that the lateral incisors help in guiding the canine down through the grafted area. The number of complications was scarce, although both groups demonstrated some gingival retraction with a longer crown length at the cleft side central incisor. Conclusion The findings of this study have changed our strategy in bone grafting. Timing of orthodontic treatment and bone grafting has been more varied depending on the position and presence of teeth in the cleft area. Bone grafting of the alveolar process is not just a local treatment of a bony defect, but in respect to the burden of treatment, bone grafting of the alveolar process has to be planned in accordance with orthodontic treatment and maxillofacial growth.

Aim.This study was designed to evaluate the immediate and long-term results of the Protocol of complex rehabilitation of 15 Kubanskij nauchnyj medicinskij vestnik 2018; 25 (5) children with bilateral through-cleft lip and palate (BTCLP) developed by the Department of pediatric dentistry, orthodontics and maxillofacial surgery of KSMU.Materials and methods. There was conducted the evaluation of the immediate and long-term results of the complex treatment of 25 patients with BTCLP aged 0 to 18 years according to the Protocol developed by the Department of pediatric dentistry, orthodontics and maxillofacial surgery of KSMU.Results. There was carried out a detailed analysis of the results of the application of the function-forming plate (FFP) in patients with BTCLP aged 0 to 1 year. The results of the models measurement in dynamics showed a significant growth and development of the upper jaw, the approximation of the shape and size of the upper alveolar arc to the norm, reducing the distance between its fragments to the minimum. There was established that long-term gradual orthodontic treatment provides conditions for physiological growth and development of the facial skeleton and for the formation of physiological occlusion in children with BTCLP. The usage of gentle methods of uranoplasty reduces the risk of dentoalveolar anomalies in children with BTCLP. The complex of therapeutic measures and terms of surgical intervention should be planned individually. The elimination of the defects of the alveolar process of the upper jaw by the method of autoosteoplasty is a necessary step in the complex rehabilitation of children with BTCLP during the periods of changing and forming permanent dentition. The planning of the stage of prosthetics of patients with BTCLP is individual and involves the creation of conditions for fullfledged functions of chewing, swallowing and speech, and it is recommended to carry it out with the help of modern aesthetic constructions that ensure the preservation of the results of the complex, including orthodontic, treatment.Conclusion.The analysis of the photographs of the face, TRG, CT and jaws diagnostic models obtained during the treatment of children and adolescents with congenital cleft lip and palate confirms the high morphofunctional and aesthetic result of the application of the developed at the Department of pediatric dentistry, orthodontics and maxillofacial surgery of KSMU Protocol of comprehensive rehabilitation of children with BTCLP.

Summary Aim The development of gingival recessions has been associated with orthodontic treatment; however, a clear etiology is still unknown. The aim of the present study was to further clarify potential association between the development of labial and lingual recessions and inclination of the lower incisors during orthodontic treatment, vertical facial morphology, width of the alveolar bone process, height and width of their symphysis after orthodontic treatment and at long-term retention. Methods On dental casts and good quality lateral cephalograms of 126 orthodontically treated patients, relevant measurements were performed and gingival recessions were assessed and recorded before, immediately after treatment and at long-term retention. Results Taking into account the whole sample at three different occasions, on the buccal side, the lateral incisors have significantly less recessions than the central incisor. On the lingual side, tooth 32 presented with lower risk of recession compared to all other three incisors. No association was found between the width of the alveolar bone process at the apex (Wapex), at the level of the crest (Wcrest) and at mid of the root (Wmid), the width (D), the vertical skeletal pattern (AnsPns-Go’Me) and the onset of buccal or lingual recessions. Development of new recessions was clearly associated with males and with increasing age. The symphysis height (Me-Wcrest) was statistically related with the onset of lingual recessions on 32 and 42. The ratio between the symphysis height and the width at the crest level demonstrated a statistically significant association with the presence of buccal and lingual recessions. Excessive proclination (≥10°) of the lower incisors demonstrated an association with the onset of recessions in 25 per cent of the cases. Conclusion Based on the sample of this study, there is some evidence that increased symphysis height (Me-Wcrest), and ratio between the symphysis height and the width at the crest level as well as big change of lower incisor inclination during treatment are associated with the development of recessions.

Abstract The role of lower third molars in lower incisor crowding is a debatable topic. Some believe the presence or eruption of lower third molars is associated with the crowding of mandibular incisors, others negate such association. Thirty-two newly debonded orthodontic patients, with ages ranging from 14-19 years, were randomly selected. No retainers were used for the lower dental arch. Removal of tight interproximal contacts of the lower anterior teeth was created and maintained by periodic abrasive stripping every 2-3 months, if needed. The cases were followed up for one year. Orthopantomographs (OPGs) and study casts were taken at debonding (post-treatment) and at the end of the one year follow up (post retention). Statistical analysis of the lower third molar conditions – erupted, unerupted, or missing with or without sufficient space for their eruption – versus re-crowding of lower incisors was evaluated using Fisher's Exact Test. The results of this pilot study revealed there was no significant correlation between the different conditions of the lower third molars versus lower anterior re-crowding in the absence of tight interproximal incisal contacts; however, a larger sample size is needed to verify such findings.

Congenital Condition

Oligodontia is a condition in which the patient has more than six ageneses, excluding the third molars. Whereas the absence of one tooth is quite common, oligodontia is a rare congenital condition that can happen with or without the syndrome. The condition happens due to disturbances during odontogenesis process. Management of oligodontia is a long-term process, and it involves prosthetic, restorative, and orthodontic treatment to support the oral function and esthetic of the patient. This article aims to report a rare case of agenesis of 13 permanent teeth (excluding third molars) in an 11-year-old girl and her treatment plan.
