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.

Objective The treatment of a patient with a complete unilateral left cleft lip and palate, agenesis of the left upper second premolar, and a severely malformed left upper lateral incisor is reported. Treatment included placement of an autologous bone graft from the left iliac crest into the alveolar cleft at 8 years of age and transplantation of a lower premolar into the reconstructed alveolar process at 10 years of age. During the succeeding orthodontic treatment, the dental arches were aligned and corrected toward a Class I molar occlusion. One year after the end of treatment, the status of the transplanted premolar was good.

AbstractOur pilot study reports twenty-six cases of resolved chronic otitis media in which the human, cadaveric styloid process was used as an ossicular graft material. A maximum follow-up of one year is presented in this paper. There was no extrusion or rejection of the styloid processes. Hearing improvement with a closure of the air-bone gap to within 10–15 dB. of the pre-operative bone conduction was found in most cases. So far the styloid process has proved to be an ideal ossicular graft though the long-term results are yet to be seen.

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.
