“…With regard to the quality standard of the retrieved investigations, it ranged from low (four studies 26,29,31,37 ) to medium/high (five studies 24,27,30,34,39 ). The only RCT 39 analyzed a very specific aspect of orthopedic treatment of Class III malocclusion (use of rapid maxillary expansion [RME] in combination with a facial mask vs no use of the RME), and the reported results were in the short term.…”

Objective: To assess the scientific evidence on the effectiveness of early orthopedic treatment in Class III subjects. Materials and Methods: A literature survey was performed by applying the Medline database (Entrez PubMed). The survey covered the period from January 1966 to December 2005 and used the Medical Subject Headings (MeSH). The following study types that reported data on the effects of Class III treatment with orthopedic appliances (facial mask, chincup, FR-3) on intermaxillary sagittal and vertical relationships were included: randomized clinical trials (RCTs), and prospective and retrospective longitudinal controlled clinical trials (CCTs) with untreated Class III controls. Results:The search strategy resulted in 536 articles. After selection according to criteria for inclusion and exclusion, 19 articles qualified for the final review analysis. One RCT and 18 CCTs were retrieved. Conclusion:The quality standard of the retrieved investigations ranged from low (four studies) to medium/high (five studies). Data derived from medium/high quality research described over 75% of success of orthopedic treatment of Class III malocclusion (RME and facial mask therapy) at a follow-up observation 5 years after the end of orthopedic treatment.

“…Some studies indicated that the chincup had no effect on retarding mandibular growth but only produced a backward rotation of the mandible. 5,17 Deguchi et al 18 reported that short-term chincup treatment showed a significant backward rotation of the mandible, while long-term application of the chincup force significantly inhibited growth of the ramus height and body length of the mandible and showed a significant closing of the gonial angle. Some investigators also reported that changes in the horizontal maxillary and mandibular relationship obtained with chincup therapy remained stable after fixed orthodontic treatment.…”

Objective: To assess the efficacy of chincup therapy for mandibular growth retardation in early orthopedic treatment of Class III malocclusion. Materials and Methods: An electronic search for articles reporting randomized clinical trials, controlled clinical trials, and cohort studies testing the efficacy of chincup appliance for Class III malocclusion published up to the present was done through four databases: Cochrane Central Register of Controlled Trials (CENTRAL; to March 2010), MEDLINE (1950-March 2010, EMBASE (1980-March 2010), and CBM (1978-March 2010. Study quality assessment and data extraction were done by two reviewers independently. Meta-analysis was done with the assistance of Revman 5.01. Results: The search resulted in 50 articles. After selection following the established criteria, four cohort studies qualified for the final review analysis. The results showed that chincup therapy decreased SNB angle and increased ANB angle; the total pooled weighted mean difference values (95% confidence interval) were 21.18 (21.69, 20.67; P , .00001) and 1.90 (0.60, 3.21; P 5 .004), respectively. Two studies showed a increase in Gonial angle (P , .05) but no significant change in the mandibular length (Cd-Gn; P 5 .059 and .39, respectively). One study indicated that chincup therapy exerted no effect on mandibular growth retardation, and mandibular growth continued after the treatment in a downward direction. Conclusion: There are insufficient data in these studies to make clear recommendations regarding the efficacy of chincup therapy in the retardation of mandibular growth.
