Early Orthodontic Intervention Using Twin Block Appliance Combined with Lip Bumper for Jaw Alignment and Dental Development
Abstract: Class II malocclusion associated with mandibular retrusion and hyperactive perioral musculature can adversely affect facial esthetics, oral function, and occlusal development in growing patients. Early orthopaedic correction during active growth offers the opportunity to modify skeletal relationships and achieve stable functional outcomes. This case report describes the management of a 9-year-old boy presenting with increased overjet, incompetent lips, vertical growth pattern, and hypermentalis activity. Treatment involved construction of a Twin Block with a lip bumper to relieve lower lip pressure and enhance neuromuscular balance. Progressive wear resulted in overjet reduction, improvement in lip competence, soft-tissue relaxation in the chin region, and establishment of a Class I occlusion.
Keywords: twin block, lip bumper class ii malocclusion, functional appliance
