Treatment of ankylosed mandibular first permanent molar

Abstract

This report describes the treatment of a 21-year old patient with an ankylosed mandibular right first permanent molar. The tooth was noticeably infraoccluded when the patient was first seen, at age 9. Over the next 11 years, several interventions, as well as periods of observation, were undertaken to bring the infraoccluded tooth into occlusion. This was finally accomplished by using a microscrew implant. The final treatment and the treatment procedures during the adolescent period are reported here.
