“…FM therapy represents the gold standard for correcting skeletal Class III malocclusion in growing subjects [1][2][3][4][5][16][17][18][19]. Several factors play a substantial role in terms of efficacy and effectiveness of orthopedic Class III treatment, including individual skeletal pattern, protraction device adaptation, patients' compliance, and device wear-time [20][21][22][23][24]. Stocker et al [23] and Ozkalayci and Cicek [24] analyzed wearing time and patient compliance with FM reporting a significantly lower wearing time than the prescribed instructions.…”

The not customized design of both FM models can cause poor device adaptation to the patient's face.…”

Background: Maxillary protraction with facemask (FM) is an orthopedic approach for treatment of Class III growing patients. Aim of the present investigation was to analyze tension loads produced by two different facial mask (FM) designs on facial skin of subject with skeletal Class III. Methods: A three-dimensional (3D) geometry of Delaire and Petit FM models were reconstructed from the original Computer Aided Design (CAD) 3D prototype using software package (ANSYS 5.7). A traction load of 9.8 N inclined of 30°to the occlusal plane was applied combining analytical FM models with a 3D facial model. Resulting stresses and deformations on the skin layer were tested through the von Mises yield criterion. Results: Overall tensions were mostly developed on the chin area, while lower stresses were observed on forehead area for both FM designs. When Delaire FM model was tested, maximum stresses were observed on the upper border of the chin cup corresponding to the inferior lip and to marginal gingiva of lower incisors. After Petit FM application, maximum stresses were more extensively localized at the level of both upper border and central area of the chin. Stresses measured on the chin area were significantly higher with Petit FM when compared with Delaire FM (44 KPa versus 29 KPa, respectively). Conclusions: Delaire FM determined lower stresses and tensile tensions than Petit FM model. Highest tensions were observed at the level of chin cup area for both Delaire and Petit FM. Stresses following Delaire FM application were mostly observed on the upper border of the chin cup, while Petit FM determined stresses more extensively distributed to the central area of the chin.

“…9 The facemask appliance needs to worn by the patient for 12 to 14 hours daily. 10 It is recommended that the age for effective treatment was ranges between 6 to 8 years (early mixed dentition) or 9 to 12 years (late mixed dentition). 11 Facemask along with rapid maxillary expansion (RME) to protract the maxilla has become a treatment protocol in cases with maxillary deficiency.…”

Maxillary and mandibular skeletal discrepancies are one of the commonly prevailing malocclusion in the childhood. Many a time it is ignored by the parents as well as the clinicians. It can present itself with aesthetic, functional and psychological problems of the child. Proper identification, diagnosis and treatment planning at the proper age can lead to correction and improvement in the overall facial balance and psychological esteem of the child. Over the years orthopedic and myofunctional appliances has been used to correct Class II and Class III skeletal malocclusion in a growing child. Face mask therapy with RME has been used as treatment choice to treat a patient with skeletal Class III malocclusion. Orthopedic correction in the early stage of life can eliminate the severity and further complex treatment modalities in the later stages of life. This case report describes the treatment of male child aged 12 years who had skeletal Class III malocclusion with maxillary deficiency. The treatment was done in two phases; orthopedic correction was done initially using RME Facemask followed by fixed orthodontic correction. There was overall improvement in the facial profile and occlusion of the patient post treatment.
