Primary Failure of Eruption: A Cause of Posterior Open Bite

Abstract

Primary eruption failure is a poorly understood condition in which the teeth fail to erupt in oral cavity in absence of any local or systemic factors. First and second molars are most commonly affected but one or more number of teeth, primary or permanent can be partially or completely affected. The orthodontic or surgical methods to get such teeth in occlusion have failed miserably. The early diagnosis of primary eruption failure (PEF) will allow the dentist to accurately rehabilitate the patient without wasting any time on treatments which are bound to fail.
