Class II malocclusions have several treatment protocols, and we are increasingly moving towards more conservative orthodontics, avoiding dental extractions whenever possible. A great alternative for treatment in standard II patients has been the use of mandibular protraction appliance, which promote correction of this malocclusion. In the article in question will be reported the use of the Twin Force Bite Corrector appliance in the correction of a unilateral class II. Objective: case report of malocclusion with mandibular propellant. Method: One-phase treatment with the use of a fixed orthodontic appliance associated with a fixed mandibular propulsion orthopedic appliance, Twin Force Bite Corrector (TFBC). Result and Conclusion: The treatment was able to promote the reduction of the overjet, obtaining a stable Class I molar and canine relationship with coincident midlines and the improvement of the soft tissue profile.

Objective: To compare changes in WALA ridge and mandibular dental arch dimensions in orthodontic patients treated with a passive self-ligating system and conventional appliances.Design: Original paper.Setting: Orthodontic department at Inga University Center, Maringá, PR, Brazil.Materials and Methods: Pretreatment (T1) and posttreatment (T2) dental casts of 60 patients with Class I malocclusion treated with slight to moderate crowding that were divided into two groups. Group 1: 30 patients treated with a passive self-ligating system, at a mean initial age of 17.68 years and mean treatment time of 2.31 years. Group 2: 30 patients treated with conventional appliances, at a mean initial age of 19.23 years and mean treatment time of 2.56 years. Measurements were taken using a digital caliper directly on pre and posttreatment dental casts to evaluate the transversal dimension behavior of the mandibular dental arch and the WALA ridge width.Results: Self-ligating group presented an increase in WALA ridge width and mandibular transversal dimensions significantly greater than the conventional group, with the exception of intermolar cusp tip distance and intercanine WALA ridge. There was no statistically significant difference between the groups. There was also observed a significantly greater increase of the transversal buccal axis dimensions in the premolar area when compared to the WALA ridge increase in both groups.Conclusions: Treatment with a passive self-ligating system resulted in a significantly greater increase of the WALA ridge width and mandibular arch dimensions when compared to conventional appliance.

We present an account of a case of a malocclusion Class III with anterior crossbite where the chosen therapeutic option was the compensatory treatment. The compensatory orthodontic treatment of poor class III occlusion has been the first choice in dental offices because it is less aggressive to patients, especially in cases of mild or moderate skeletal involvement. We used to treat the Roth prescription with self-ligating brackets of the GAC brand - In Ovation R and the wires following the same brand with the projector. A positive horizontal overlap was achieved with the aid of further acrylic stand, made of laboratory, intermaxillary elastics and flaring bows with TMA wire. The excellent patient compliance with treatment, as well as the precise brackets and accessories are essential for the proper conduct and completion of the case. After 11 months, treatment was completed with very satisfactory results that will be presented throughout this work. [ABSTRACT FROM AUTHOR]
