- Abstract
- The infraocclusion is defined as a condition, in which teeth are present with their occlusal surface below the neighboring teeth, and long after, they reach occlusion. The most common cause of infra-occlusion is thought to be ankylosis. The treatment options for patient with infraocclusion of primary molars are observation, restoration and surgical removal of the affected teeth. We report a case of 8 - year - old boy who visited our clinic for consultation of orthodontic treatment. The patient was diagnosed by multiple infraoccluded primary molars with permanent successors. Surgical extraction were performed on primary molars. After follow-up of 7 months period, #44, 45 were erupted and the degree of posterior open bite was decreased.
