ABSTRACT Objective:  To assess the maxillary second molar (M2) and third molar (M3) inclination following orthodontic treatment of Class II subdivision malocclusion with unilateral maxillary first molar (M1) extraction. Materials and Methods:  Panoramic radiographs of 21 Class II subdivision adolescents (eight boys, 13 girls; mean age, 12.8 years; standard deviation, 1.7 years) before treatment, after treatment with extraction of one maxillary first molar and Begg appliances and after at least 1.8 years in retention were retrospectively collected from a private practice. M2 and M3 inclination angles (M2/ITP, M2/IOP, M3/ITP, M3/IOP), constructed by intertuberosity (ITP) and interorbital planes (IOP), were calculated for the extracted and nonextracted segments. Random effects regression analysis was performed to evaluate the effect on the molar angulation of extraction, time, and gender after adjusting for baseline measurements. Results:  Time and extraction status were significant predictors for M2 angulation. M2/ITP and M2/IOP decreased by 4.04 (95% confidence interval [CI]: −6.93, 1.16; P  =  .001) and 3.67 (95% CI: −6.76, −0.58; P  =  .020) in the extraction group compared to the nonextraction group after adjusting for time and gender. The adjusted analysis showed that extraction was the only predictor for M3 angulation that reached statistical significance. M3 mesial inclination increased by 7.38° (95% CI: −11.2, −3.54; P < .001) and 7.33° (95% CI: −11.48, −3.19; P  =  .001). Conclusions:  M2 and M3 uprighting significantly improved in the extraction side after orthodontic treatment with unilateral maxillary M1 extraction. There was a significant increase in mesial tipping of maxillary second molar crowns over time.

ABSTRACT Objective: We aimed to investigate the prevalence, distribution, angular position, and depth of third molar impaction in a Turkish orthodontic patient population. Materials and Methods: We retrospectively reviewed the panoramic radiographs, intraoral photographs, and dental casts of 207 patients (62 men and 145 women; age 20-39 years) who had undergone orthodontic treatment at a university department of orthodontics for impacted third molars (ITMs). A comprehensive chart review of all subjects was conducted. Patient and treatment-related data were recorded in a digital database for comparative analysis. Results: The prevalence of ITMs was 54.1%, and no statistically significant gender differences were evident (61.3% in men and 51.0% in women; P = 0.23). The frequency of maxillary ITMs was 49.3% (148 of 300 teeth) while that of mandibular ITMs was 50.7% (152 of 300 teeth). The most frequently observed angulations of impaction were mesioangular for the mandible (65.1%), and distoangular for the maxilla (64.2%). Of all the ITMs analysed, 61% were partially buried in bone and 39% were completely buried. Conclusions: Third molar impaction was evident in 54.1% of a group of Turkish orthodontic patients aged 20-39 years, and there was no statistically significant gender bias. Mesioangular and distoangular inclinations were the most common in the mandible and the maxilla, respectively.

Pathology of an eruption of wisdom teeth is importance for a military odontology because the vast majority of the military contingents on age coincides with time of their physiological eruption (16-40 years). In work, on the basis of clinic-radial methods of a research, features of a teething of wisdom at young people of military age are studied and analyzed 3D-tomograms and orthopantomograms of 325 servicemen aged from 18 up to 27 years. During work estimated existence of wisdom teeth on top and lower jaws, extent of their eruption, existence of a retention (or dystopias) and also an adentia or loss of wisdom teeth. It was established that most often eruption of the third molar teeth of jaws at recruits occurs at the age of 23-27 years, at the same time at a series of recruits eruption of the lower wisdom teeth usually is followed by various complications, such as pericoronitis, an acute purulent periostitis of a mandible, a false «acute periodontitis» of the lower second molar tooth that becomes perceptible at mesial shift of a wisdom tooth and dense contact of its coronal part with a distal root of the second molar tooth. The essential value for a full-fledged teething of wisdom has their situation in an alveolar process (part) of a jaw, and further - in dentition. It in many respects defines a clinical picture of the shown eruption complications and also tactics of stomatologic treatment - orthodontic treatment, surgical treatment or their combinations. The infectious and inflammatory complications bound to the complicated their eruption (85,93% of cases) served as the reasons of an exodontia of wisdom. In 14,07% of cases wisdom teeth on both jaws were extracted in a planned order in connection with the forthcoming orthodontic treatment on elimination of dentoalveolar anomalies. Thus, terms and features of a teething of wisdom at recruits need to be considered in clinical practice of a military odontology as their military service can pass in specific living conditions and activity of troops and health service, and at complications of a teething of wisdom the acute stomatologic surgical management, including stationary is in most cases necessary.

Third Molar Eruption

ABSTRACT Objective: This article describes the orthodontic treatment performed on an adult patient with multiple dental losses. Case report: A female patient, 20 years and 4 months old, presented with the following conditions: absence of teeth #26, #35, #36 and #46; semi-impacted tooth #48; inclined molars adjacent to an edentulous space; canines and premolars in a Class II relationship; a convex profile; biprotrusion; and forced lip sealing. Results: Space in the region of tooth #26 was closed, as well the space of tooth #46; tooth #48 erupted and followed mesial movement passively; space of the region of tooth #35 was maintained for the placement of a dental implant; uprighting of tooth #37 was obtained. Aesthetic and functional goals of the treatment were achieved. Results remained stable 10 years after the end of the treatment. Conclusion: The modified helical loop could be effectively used in orthodontic mechanics to close edentulous spaces. Passive semi-impacted mandibular third molar eruption and mesialization can occur in adults when proper space is provided.
