Developing Class III Malocclusion in most of the cases affects dentofacial appearance. The goal of this study is to investigate the changes in the facial appearances in treated patients withFace mask orthopedic treatment and untreated Class III patients. The sample consisted 49 patients (boys and girls),with average age of 9 years, who had a Class III Malocclusion with an anterior crossbite and a component of maxillary deficiency. 28 of them were treated with protraction Face mask- Delair mask (petit tipe), and the other 21 were presenting the control group consisted of untreated Class III Patients.In treated group pretreatment and posttreatment cephalometric radiographs from 28 patients(15 males and 13 females) were analyzed and compared with the results of cephalometric analyzes in untreated group(observation period of 1 year). Results from these study showed forward displacement of maxilla(SNA p<0.05),increasing of maxillary length(Co-A p<0.05)correction of maxillary-mandibular relationship(ANB p<0.05) in treated group while in untreated groupvalues for the parameters in the upper jaw and inter jaw relationship before and after the observation period of 1 yearshowed no statistically significant changes pointing to the negative impact of incorrect skeletal terms in Class III growing patients.Based on our findings we can concluded that in Class III patients there is a big motivation for orthodontic treatment because their dentofacial appearance deviates from sociocultural norms.Therefore, an important objective of accepting maxillary protraction treatment in Class III malocclusion is providing nonsurgical alternative in the treatment and improving the physico-social wellbeing and appearance of the patients, especially during their teenage years.

The Ideal

The orthodontic treatment of class III malocclusion with a maxillary deficiency is often treated with maxillary protraction with or without expansion. Skeletal and dental changes have been documented which have combined for the protraction of the maxilla and the correction of the class III malocclusion. Concerning the ideal time to treat a developing class III malocclusion, studies have reported that, although early treatment may be the most effective, face mask therapy can provide a viable option for older children as well. But what about young adults? Can the skeletal and dental changes seen in expansion/facemask therapy in children and adolescents be demonstrated in this age group as well, possibly eliminating the need for orthodontic dental camouflage treatment or orthognathic surgery? A case report is presented of an adult class III malocclusion with a Class III skeletal pattern and maxillary retrusion. Treatment was with nonextraction, comprehensive edgewise mechanics with slow maxillary expansion with a bonded expander and protraction facemask.

ABSTRACT Introduction Chin cup (CC) therapy has been used as the traditional appliance for treating class III malocclusion during mixed dentition period. The aim of this study was to investigate the effect of CC on the improvement of skeletal and dentoalveolar skeletal changes in class III patients during mixed dentition stage. Materials and methods A total of 30 patients (7–9 years old) with skeletal class III malocclusion were selected based on clinical and cephalometric examination. Out of 30 patients, 20 underwent CC therapy. All orthodontic records and measurements were taken before and after treatment. Similar records were collected from the control group. The lateral cephalometric films were traced before and after treatment and analyzed. Results There was a significant improvement in maxillary and the mandibular skeletal measurements after CC therapy. Improvement of ANB angle and an increase in Wits appraisal have been detected in the treated group according to intermaxillary skeletal variables. Conclusion The study concluded that the CC therapy is effective for correcting skeletal class III malocclusion along with positive changes in the dentoskeletal variables during the mixed dentition stage.

SummaryObjectivesThe objective of this study was to analyze soft tissue changes produced by rapid maxillary expansion and facial mask therapy in growing Class III patients.MaterialsThe treated group consisted of 32 Caucasian patients (15 females and 17 males) with dentoskeletal Class III malocclusion treated with the Face Mask Protocol (FMP, rapid maxillary expander, facial mask, and removable lower bite-block). All patients were evaluated before treatment (T1; mean age, 8.4 years), at the end of active treatment (T2; mean age, 10.7 years), and at a post-pubertal follow-up observation (T3; mean age, 15.8 years). The treated group was compared with a matched control group of 20 untreated subjects (10 females and 10 males) with dentoskeletal Class III malocclusion. Statistical comparisons between two groups were performed with the independent samples t-test (P < 0.05).ResultsSignificant improvements were found during the long-term T1–T3 interval for profile facial angle (–5.8°), nasolabial angle (–4.4°), mandibular sulcus (–10.3°), upper lip protrusion (+0.7 mm), and lower lip protrusion (–1.1 mm) in the treated group. No significant post-pubertal effects were found in terms of lower face percentage between two groups.LimitationsThis study has a retrospective design and it used a historical control sample.ConclusionThe FMP induced positive effects on soft tissue facial profile with a good long-term post-pubertal stability.

Retrospective Comparative Study

Abstract Objective: To compare the effectiveness of Reverse Twin-Block therapy (RTB) and protraction face mask treatment (PFM) with respect to an untreated control in the correction of developing Class III malocclusion. Materials and Methods: A retrospective comparative study of subjects treated cases with either PFM (n  =  9) or RTB (n  =  13) and untreated matched controls (n  =  10) was performed. Both the PFM and control group samples were derived from a previously conducted clinical trial, and the RTB group was formed of consecutively treated cases. The main outcome variables assessed were skeletal and dental changes. Lateral cephalograms were taken at the start and end of treatment or during the observation period. Analysis of variance was used to compare changes in cephalometric variables arising during the study period in the lateral group. Linear regression analysis and an unpaired t-test were used to determine the impacts of treatment duration and gender, respectively. Results: Significantly greater skeletal changes arose with PFM therapy than with RTB therapy or in the control group (SNA, SNB, and ANB; P &lt; .001). The dentoalveolar effects of RTB therapy exceeded those of PFM treatment, with significantly more maxillary incisor proclination (P &lt; .001) and mandibular incisor retroclination (P &lt; .006) arising with treatment. Conclusions: Both appliances are capable of correction of Class III dental relationships; however, the relative skeletal and dental contributions differ. Skeletal effects, chiefly anterior maxillary translation, predominated with PFM therapy. The RTB appliance induced Class III correction, primarily as a result of dentoalveolar effects.

Maxillary Deficiency

The orthodontic treatment of Class III malocclusion with a maxillary deficiency is often treated with maxillary protraction either with or without maxillary expansion. The routine procedure for rapid maxillary expansion includes banding on first premolars/first deciduous molars and the permanent first molars. However in some patients who are esthetically very conscious, banding of the first premolar would not be a good esthetic option. So for such circumstances we have designed a modified hyrax splint, which does not need the first premolars to be banded.

The etiology of class III malocclusion remains unknown. The present study investigates the relationship between craniofacial morphology and premaxillary suture fusion to test the hypothesis that class III malocclusion may be related to premaxillary suture fusion. Cyanoacrylate was applied to immobilize the left premaxillary suture in the experimental group. Sham surgeries in rats were used for controls. Dental impressions and radiographs were taken before and after surgery for comparison of craniofacial differences between groups. Overall cranial base lengths, craniofacial widths, and craniofacial angulations related to the anterior base showed significant differences between groups. At the end of the experiment, the growth of the snout in the experimental group was inhibited and deviated to the treated side, while no obvious change was seen in the control group. The results show that induced premaxillary suture fusion can affect craniofacial morphology and indicate that premature premaxillary suture fusion may result in class III malocclusion.

This prospective controlled trial aimed to evaluate the skeletal effect of 3.5-years bone anchored maxillary protraction (BAMP) in growing cleft subjects with a Class III malocclusion. Subjects and Method: Nineteen cleft patients (11.4 ± 0.7-years) were included from whom cone beam computed tomography (CBCT) scans were taken before the start of BAMP (T0), 1.5-years after (T1) and 3.5 y after (T2). Seventeen age- and malocclusion-matched, untreated cleft subjects with cephalograms available at T0 and T2 served as the control group. Three dimensional skeletal changes were measured qualitatively and quantitatively on CBCT scans. Two dimensional measurements were made on cephalograms. Results: Significant positive effects have been observed on the zygomaticomaxillary complex. Specifically, the A-point showed a displacement of 2.7 mm ± 0.9 mm from T0 to T2 (p < 0.05). A displacement of 3.8 mm ± 1.2 mm was observed in the zygoma regions (p < 0.05). On the cephalograms significant differences at T2 were observed between the BAMP and the control subjects in Wits, gonial angle, and overjet (p < 0.05), all in favor of the treatment of Class III malocclusion. The changes taking place in the two consecutive periods (ΔT1-T0, ΔT2-T1) did not differ, indicating that not only were the positive results from the first 1.5-years maintained, but continuous orthopedic effects were also achieved in the following 2-years. Conclusions: In conclusion, findings from the present prospective study with a 3.5-years follow-up provide the first evidence to support BAMP as an effective and reliable treatment option for growing cleft subjects with mild to moderate Class III malocclusion up to 15-years old.

Abstract Objective: To test the hypothesis that maxillary protraction appliances (MPA) have no effect on the size of the upper airway passage and craniofacial structures in adolescent patients. Materials and Methods: Twenty patients (5 male and 15 female; mean age 11.5 years) with skeletal Class III malocclusion were included in this study. The records of all patients who had maxillary protraction treatment and had lateral head radiographs taken before and after their protraction treatments were obtained from the files of treated cases. Treatment changes were determined by means of linear, angular, and area measurements. Data were analyzed statistically by means of paired t-test and correlation analysis. Results: Significant increases were observed in the width and area of the pharyngeal airway. Significant increases also occurred in the sagittal growth of the maxilla, while a clockwise rotation and inhibition of sagittal growth were observed in the mandible. Conclusions: The hypothesis was rejected. The size of the upper airway can be increased by means of MPA application.

Aim: To demonstrate the main effects on maxillary and facial profile after treatment with expansion and face mask therapy in patients pattern III Class III. Material and Method: A cross-sectional study of maxillary expansion and reverse traction performed in 4 patients with maxillary deficiency, in the pre-peak pubertal growth stage and in the mixed dentition, with cephalograms before and after treatment, using angular measurements (SNA, SNENA, ANL and 1NA) and linear (S’-ENA, S’-A, 1-NA, OVERJET, S-LS and S-LI) and plot overlays. Results: Improvement in overjet was observed, going from negative to positive in all cases treated with incisor uncrossing, although it was not statistically significant. The upper and lower labial posture with respect to the base of the nose and the ment improved significantly, represented by the measurements S-LS and S-LI, with a change from the concave profile to slightly convex. Conclusion: Class III malocclusion with maxillary deficiency treated with rapid maxillary disjunction and reverse traction with facial mask was effective in both groups, with maxillary protraction and shifting in the concave to slightly convex profile.KeywordsFacial Mask; Rapid maxillary expansion; Class III.

Class III malocclusion is one of the most difficult problems to treat. It has a multifactorial etiology involving both genetic and environmental causes. The dental and skeletal effects of maxillary protraction with a facemask are well documented in several studies. Although incorporation of expansion appliance along with facemask therapy can improve correcting both sagittal and transverse discrepancy of maxilla. The following case shows early treatment of a 9 year old boy with maxillary deficiency using an expansion screw along with facemask. Facemask therapy was followed by fixed orthodontic treatment to settle the occlusion. Treatment was completed after 14 months with positive overjet, class I molar and canine relationship on right and left side.
