“…19 Zeng et al 18 reported that orthodontic doctors should consider orthognathic surgery when the ANB angle was under −4 o and L1-MP angle was under 82 o . Ning et al 14 suggested that orthodontic camouflage treatment could achieve good results when the ANB angle was from −3 o to 0 o . However, these studies did not provide methods to specifically distinguish between patients with "borderline" surgical-orthodontic class III malocclusion.…”

Objective: The purpose of this study was to evaluate the dentoskeletal and soft tissue profile changes after extraction of two lower first or second premolars in "borderline" adult skeletal Class III cases. Methods: Twenty-eight patients with "borderline" skeletal Class III malocclusion were studied. All of them were treated by extraction of two lower first or second premolars. Lateral cephalometric radiographs taken at the start and end of treatment were analysed. Twenty-five cephalometric variables were calculated and paired t-tests were performed. Results: After treatment, no significant changes were noted in the skeletal parameters (p ≥ 0.05). Regarding the dental parameters, the L1-MP angle decreased by 8.

“…Five studies included patients treated with teeth extractions [6][7][8][9][10]. Extraction of two mandibular premolars was performed in two studies while extraction of four premolars was performed in one study [8][9][10]. One study included patients with extraction of one mandibular incisor [6].…”

“…Camouflage treatment can be carried out by different approaches and may include teeth extractions, distalization of the mandibular dentition, and use of Class III intermaxillary elastics [2,[6][7][8][9][10][11][12][13]. Different approaches result in different outcomes and an overview of the effects of camouflage treatment in adults is not available as a systematic review.…”

Google Scholar, Lilacs, and Cochrane databases, without limitations regarding publication year or language.Studies evaluating nongrowing individuals with Class III malocclusion undergoing orthodontic camouflage treatment with any orthodontic technique, including extraction and non-extraction approaches, were considered. Study selection, data extraction, and risk of bias assessment according to a modified Downs and Black checklist were performed by two independent reviewers. A third evaluator was included if disagreements emerged.Results: Nine studies were included in the review. Eight presented high risk of bias. Different methods for Class III malocclusion correction were described and included maxillary and mandibular premolar extractions, mandibular incisor extraction, Class III elastics and distalization of the mandibular dentition. Extractions in the mandibular arch resulted in lingual tipping and retrusion of the mandibular incisors, and labial tipping and protrusion of the maxillary incisors. The use of Class III intermaxillary elastics promoted proclination of the maxillary incisors, extrusion of the maxillary molars, distal tipping of the mandibular molars, extrusion of the mandibular incisors, and clockwise rotation of the mandible. Distalization of the mandibular dentition resulted in distal tipping of the mandibular molars, retroclination and retraction of the mandibular incisors, and counter clockwise rotation of the mandible.Conclusions: Treatment changes are influenced by the method used to correct the Class III malocclusion and are primarily dentoalveolar
