Lecture Description
Impacted teeth are defined as ¡®teeth that do not appear in the oral cavity at the time of normal growth¡¯ or ¡®teeth that have finished the growth of the tooth root but are not expected to be spontaneous eruption¡¯. When an impacted tooth patient visits the hospital, the orthodontist should use appropriate diagnostic data to determine the most suitable treatment methods such as observation treatment, intervention through orthodontic treatment, germ reposition or extraction. Some interaction among these options is possible. When it is decided to perform impacted tooth treatment through orthodontic approach, ¡®expecting natural eruption by securing space¡¯ is the first method to be selected. If necessary, eliminate soft tissue and/or hard tissue through surgery to expose the impacted tooth and attach a hook for traction, then select a proper orthodontic traction method to facilitate eruption. The average treatment period for impacted teeth is 12.2 months, with the longest treatment period for canine teeth and the shortest treatment period for lateral incisors. The horizontal position of the crown, age, distance from the occlusal surface to the crown, and angulation of the long axis affect the treatment period. Becker and his colleagues suggested 3 major factors of failure of impacted tooth correction. Patient-dependent factor, Orthodontist-dependent factors, and Surgeon-dependent factors. I studied the characteristics of impacted teeth in Koreans in 570 cases (316 male cases, 254 female cases) among a total of 438 patient (240 men, 198 women) who visited the Orthodontics department of Gachon University Gil Hospital from 2010 to 2019 with the address of impacted teeth. In addition, I would like to share the results by conducting a study to find out the factors that affect treatment success and treatment duration in only the maxillary canine teeth that are most frequently impacted.
