To analyze the scientific literature and compare in the results of conventional orthopedic appliances with those obtained from recent bone-anchored orthopedics for Class III malocclusion.

Materials and methods:
The literature was systematically reviewed using PubMed/Medline, Scopus, and Scirus databases up to January 2012. Articles were selected by two different researchers (kappa index = 0.83), based on established inclusion/exclusion criteria. Methodologic quality was classified as high, medium, or low quality.

The search strategy identified 1020 titles. Thirty studies were selected after applying the criteria (high quality = 9, medium quality = 21). Protraction rates differed within a range of one- to twofold between bone-anchored and dentoalveolar therapies (P < .001). All studies noted the effect of clockwise rotation on the mandible and an increase in inferior-anterior and total facial height; this was more obvious in dentoalveolar therapy than in bone-anchored orthopedics (P < .001).

Dental parameters like overjet increased significantly with both sets of groups, ranging from 1.7 to 7.9 mm with dentoalveolar therapy and from 2.7 to 7.6 mm with bone-anchored orthopedics.

    ABSTRACT: Cleft lip and palate surgery in the developing child is known to be associated with maxillary hypoplasia. However, the effects of nonsurgical manipulations on maxillary growth have not been well investigated. The authors present the contribution of orthodontic dental space closure with canine substitution to maxillary hypoplasia and the need for orthognathic surgery. Cleft lip/palate and cleft palate patients older than 15 years of age were reviewed for dental anomalies, orthodontic canine substitution, and Le Fort I advancement. Skeletal relationships of the maxilla to the skull base (SNA), mandible (ANB), and facial height were determined on lateral cephalograms. Logistic regression analyses were performed to estimate odds ratios. Ninety-five patients were reviewed (mean age, 18.1 years). In 65 patients with congenitally missing teeth, 55 percent with patent dental spaces required Le Fort I advancement. In contrast, 89 percent who underwent canine substitution required Le Fort I advancement (p = 0.004). Canine substitution is associated with a statistically significant increase in maxillary retrognathia when compared with dental space preservation on lateral cephalograms (mean SNA, 75.2 and 79.0, respectively; p = 0.006). Adjusting for missing dentition, logistic regression analyses demonstrated that canine substitution is an independent predictor for orthognathic surgery (OR, 6.47) and maxillary retrusion defined by SNA < 78 (OR, 8.100). The coordination of orthodontia and surgery is essential to cleft care. The authors report a strong association between orthodontic cleft closure using canine substitution with maxillary hypoplasia and subsequent Le Fort I advancement, and suggest systematic criteria for management of cleft-related dental agenesis.

    ABSTRACT: Objective: To analyze the long-term stability of rapid maxillary expansion (RME) and protraction from chincup therapy in girls with Class III malocclusion. Materials and methods: Twenty-two girls (mean age = 9.1 ± 0.6 years) with Class III malocclusion were treated with combined RME and protraction from a chincup, followed by fixed appliances. Lateral cephalograms were evaluated before treatment, at the end of a two-phase treatment protocol (mean age = 15.1 ± 1.1 years), and 10.9 ± 0.5 years after the end of treatment (mean age = 27.5 ± 0.5 years). The control group consisted of 22 matched girls with skeletal Class I malocclusion. Results: After treatment, the Class III group showed significant improvement of the Class III malocclusion, mainly due to changes in the mandible (ie, SNB angle decreased 1.8 ± 1.6°) and significant improvement of the sagittal maxillomandibular relationship (Wits appraisal increased 2.6 ± 2.1 mm; ANB angle increased 1.0 ± 0.3 mm). These changes remained stable for an average of 10 years after the end of therapy. No tendency toward relapse was detected, and the mandibular position showed favorable outcomes. Conclusions: RME and protraction from chincup therapy led to successful long-term outcomes in 18 of 22 patients (81.8%). This treatment approach can be considered an efficient therapy in growing girls with mild skeletal Class III malocclusion caused by maxillary retrusion and mandibular protrusion.

    ABSTRACT: The purpose of this work was to statistically evaluate the outcomes achieved by isolated extraction of mandibular teeth (second premolars or first molars) for Class III compensation. Part A of the study dealt with the quality of outcomes at the end of active treatment, using weighted Peer Assessment Rating (PAR) scores determined on the basis of casts for 25 (14 female and 11 male) consecutive patients aged 16 ± 1.7 years at the time of debonding. These results were compared to the scores in a randomly selected control group of 25 (14 female and 11 male) patients who were 14.7 ± 1.9 years old at debonding. Part B evaluated the long-term stability of the outcomes based on 12 (all of them female) patients available for examination after a mean of 11.8 years. The mean weighted PAR scores obtained in both study parts were analyzed for statistical differences using a two-tailed paired Student's t-test at a significance level of p ≤ 0.05. Mean weighted PAR scores of 4.76 ± 3.94 and 3.92 ± 3.44 were obtained in the Class III extraction group and the control group, respectively, at the end of active treatment. This difference was not significant (p = 0.49). Among the 12 longitudinal patients, the mean score increased from 4 ± 3.46 at debonding to 6.25 ± 3.67 by the end of the 11.8-year follow-up period. This difference was significant (p = 0.0008). Treatment of Class III anomalies by isolated extraction of lower premolars or molars can yield PAR scores similar to those achieved by standard therapies. These scores, while increasing significantly, remained at a clinically acceptable level over 11.8 years. Hence this treatment modality-intended for cases that border on requiring orthognathic surgery-may also be recommended from a long-term point of view.
