Abstract
Objective: The aim of this article is to highlight the method of construction and use a simple removable appliance termed as "Modified Hawley’s appliance with inverted labial bow" to treat pseudo class III malocclusion
Case Report: A female patient aged 16 years, presented with chief complaint of having a monkey bite; the lower anterior teeth overlapping the upper teeth and abnormal concave facial profile. On clinical examination the dental relationship suggested retroclined upper and lower incisors. The incisors were in end-to-end relationship with posterior open bite when the mandible guided in centric relation. However, due to a premature contact between upper and lower incisors an anterior functional mandibular shift in centric occlusion causes anterior cross-bite. Therefore, the diagnosis was a pseudo Class III malocclusion.
Treatment was done in two phases. Phase 1 treatment was done by "Modified Hawley’s appliance with inverted labial bow" to have positive overbite and overjet accomplished in 4 month and in phase II treatment was done with fixed appliances to align teeth and have proper over bite and overjet and it was accomplished in 8 months.
Conclusions: Modified Hawley’s appliance with inverted labial bow is easy to construct and patient friendly appliance to correct anterior crossbite in Pseudo class-III malocclusion
