A case of bilateral posterior open-bite is reported since it is unusual to find the mandibular maxillary molars on both sides in infraclusion.
T
he varying nature of maxillofacial deformities which jeopardize the functions of the stomatognathic system and hamper the esthetic status of the face has been widely reported. Open-bite is such a condition. Open-bite may be anterior or posterior. Posterior open-bite is an extremely rare condition and is generally unilateral. The present case is unique because of bilateral involvement; moreover, it resulted from in*Lecturer. **Reader and Head of the Department of Dental Surgery. ***Reader, Department of Dental Surgery.

and
fraclusion of posterior teeth in both mandibular and maxillary arches. CASE REPORT The patient was a 25year-old man who had observed his teeth in nonclosure position in the posterior region on both right and left sides at the age of about 1.5years (Fig. 1). He continued using his anterior teeth for mastication. Later, excessive attrition of the anterior teeth caused him concern and he visited the Department of Dental Surgery, Institute of Medical Sciences, Banaras Hindu University, Varanasi, India.

The bilateral posterior open-bite appeared to be the result of infraclusion of the teeth in the posterior segments which probably resulted from the ankylosis of the teeth. In the mandibular arch, the possible cause seemed to be an infection followed by sclerosis of the area around and adjacent to the first molars (Fig. 2). The infraclusion of the maxillary posterior teeth may have been caused by the position of the tongue. Reprint
