Abstract
March 2004, a two year old patient visited for a check-up Chigusa dental clinic, a Japan Health Care Dental association member clinic. Though overbite and crowding in the anterior region were seen in the deciduous dentition, at this point no corrective intervention was made and six-monthly maintenance was started. Immediately prior to completion of permanent dentition, the patient was introduced to Arimatsu orthodontic office. Due to upper and lower anterior crowding and Angle Class II malocclusion seen in the permanent dention, upper first premolars and lower second premolars were extracted. Orthodontic treatment was carried out according to the plan the patient agreed to at the first visit, aiming for betterment of alignment of teeth, occlusion and the lip morphology. The treatment period was 21months, and following the treatment an orthodontic retainer is used and the patient has been receiving maintenance care at two dental clinics. For two white spot lesions were seen prior to orthodontic treatment, increase of caries lesions was a major concern. As of 14years old, there has been developed only one additional white spot. This is a successful case of collaborative effort by two clinics, resulting in sound teeth and occlusion.
