“…[10][11][12][13] These results were often confirmed in controlled trials that usually included combined maxillary expansion and FM therapy. [14][15][16][17][18][19][20][21] Clinical studies have also shown variable effects of maxillary protraction therapy on the amount of mandibular growth, with a tendency toward Class III relapse when the mandible rotated downward and backward during treatment.

Introduction:In this cephalometric investigation, we analyzed the treatment and posttreatment effects of an orthopedic protocol for Class III malocclusion consisting of a facial mask combined with a removable biteblock appliance. Methods: The treated sample consisted of 22 Class III patients treated with the facial mask and bite-block protocol before the pubertal growth spurt (mean age, 8.9 6 1.5 years). Treated subjects were evaluated after facial mask and bite-block therapy and at a posttreatment observation in absence of retention. The treated group was compared with a matched control group of 12 untreated Class III subjects. All treated and control subjects were postpubertal at the final observation. Significant differences between the treated and control groups were assessed with the Mann-Whitney U test (P \0.05). Results: Both angular and linear sagittal measurements of the maxilla showed significant improvements during active treatment. Significant improvements of SNA angle, ANB angle, overjet, and molar relationship remained stable during the posttreatment period. No significant effect was found in the mandibular skeletal measures. No significant protraction of the maxillary incisors or retraction of the mandibular incisors was observed. Conclusions: A bite-block appliance in the mandibular arch with a facial mask enabled effective control of mandibular rotation with progressive closure of the gonial angle. This added to the favorable maxillary outcomes of the treatment protocol. (Am J Orthod Dentofacial Orthop 2010;138:300-10)

“…As the consequence of this, the mandible rotated downward and backward, thus resulting class I skeletal relationship in this patient. [16][17][18] This effect also caused the lower anterior facial height increased. Since the patient had short lower facial height, this effect was advantageous.…”

This case report describes the treatment of a 12-years-old female with a Class III skeletal profile and dental malocclusion. The clinical examination showed concave profile, class III dental relationship, buccal crossbite on the right side, and mild crowding. The cervical vertebral maturation analysis showed the patient was on the CS3 stage. The class III malocclusion was treated with combination of banded rapid palatal expander and face mask followed by non-extraction orthodontic treatment with self-ligating system. Banded rapid palatal expander and face mask were used to improve the skeletal discrepancy. Class I maxilla-mandibular relationship was achieved along with class I molar, incisor, and canine relationship. The buccal crossbite and mild crowding were corrected, the overbite and overjet were normal, and the facial profile was improved. This case demonstrates a good result of a class III malocclusion treatment in an adolescent patient with banded rapid palatal expander/face mask and self-ligating system.

“…Many authors have used point A to prove the effectiveness of their treatment modalities, especially in the treatment of Class III malocclusion. [20][21][22][23] However, the results of the present study showed that the sagittal position of point A could be influenced by tooth movement; hence, this may lead to errors in evaluation of the true efficiency of orthodontic treatments on the skeletal base of the maxilla.…”

Objective: To examine the effect of maxillary incisor proclination due to orthodontic treatment upon the sagittal position of point A and evaluate the effect of this possible movement of point A on sella-nasion-point A (SNA) angle. Materials and Methods: A study group was formed from 25 subjects (12 male and 13 female) who had Class II division 2 malocclusion with retroclined upper incisors, and a control group was formed from 25 subjects (12 male and 13 female) who had minor crowding in the beginning of the treatment and required no or minimal maxillary anterior tooth movement. Treatment changes in maxillary incisor inclination, sagittal position of point A, SNA angle, and movement of incisor root apex and incisal edge were calculated on pretreatment and posttreatment lateral cephalographs. Results: Maxillary incisors were significantly proclined (17.33u) in the study group and not significantly proclined (1.81u) in the control group. This proclination resulted in 2.12-mm backward movement of the root apex and 5.76-mm forward movement of the incisal edge of maxillary incisors. Point A moved 1.04 mm backward (P 5 .582) and 0.48 mm (P 5 .811) forward in the study and control groups, respectively. Incisor root apex and incisal edge almost remained stable in the control group. No significant change was observed in the value of the SNA angle in both the study and control groups. Conclusions: Proclination of maxillary incisors accompanied by backward movement of incisor root apex caused posterior movement of point A. However, this posterior movement does not significantly affect the SNA angle. (Angle Orthod. 2013;83:943-947.)
