Bottom Line: In growing patients, forward repositioning of mandible by mandibular repositioning appliances is considered as a treatment of choice.The modified design enhanced the mandibular growth and contributed for the better skeletal correction of Class II malocclusion as compared to the conventional MPAs.This article highlights the design and fabrication of a splinted MPA for the correction of Class II malocclusion due to mandibular retrusion and also describes a patient managed by this appliance.

ABSTRACT
Advancement of mandible rather than tooth movement is an ideal treatment for the correction of Class II malocclusion resulting from mandibular retrusion. In growing patients, forward repositioning of mandible by mandibular repositioning appliances is considered as a treatment of choice. Correction of mandibular retrusion by the conventional mandibular protraction appliances (MPAs) is mainly due to dento-alveolar changes and by altering the design of original MPAs, these limitations were minimized. The modified design enhanced the mandibular growth and contributed for the better skeletal correction of Class II malocclusion as compared to the conventional MPAs. This article highlights the design and fabrication of a splinted MPA for the correction of Class II malocclusion due to mandibular retrusion and also describes a patient managed by this appliance.

Mentions: A 12-year-old female patient reported with the chief complaint of forwardly placed upper front teeth and small lower jaw. Family history was not contributory. Extra-oral examination revealed apparently symmetrical face, convex profile and potentially competent lips [Figure 2]. Temporomandibular joints were asymptomatic with the normal range of mandibular movements. On intra-oral examination, she was in early permanent dentition with full complement of teeth up to second molars in each quadrant, constricted maxillary arch, Class II molar relationship bilaterally, deep bite (70%) and 12 mm of overjet [Figure 2]. Her clinical visual treatment objective was positive. Cephalometric analysis revealed Class II skeletal base due to mandibular retrusion, hypodivergent mandibular growth, up-righted mandibular incisors and proclined maxillary incisors. Various cephalometric parameters are described in Table 1.
