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.
