title: Customized Modified Haas Palatal Expansion in Mixed Dentition: A Case Report.
abstract: The dental arch perimeter and transpalatal width are the most significant arch dimensions in the developing individuals. Its management during the primary, mixed and early permanent dentition are greatly important for the normal development of the dental arches and significantly improve the occlusion in adulthood. Malocclusion is a constant source of threat to the facial appearance. Severe anterior crowding and narrow maxillary arches adversely affect the smile, facial profile and consequently patient becomes handicapped socially as well as psychologically. Maxillary expansion has been used in resolving the problems of crowding, constricted arches and allow for forward growth of the mandible in growing children. This case report describes the use of a customized modified Haas appliance in intercepting the maxillary anterior crowding and gain the transpalatal width and arch perimeter of the maxilla, enhance the smile and facial profile and to allow the forward mandibular growth without any anterior occlusal interferences.
