In normal eruption sequence, permanent teeth will erupt uneventfully and replace their primary predecessors. However, sometimes teeth fail to erupt. Most of these unerupted teeth are deviated or angulated aberrantly and eventually lose their potential to erupt and are referred to as impacted teeth. Retention of teeth or impaction is one of the most common developmental dental defects seen among the eruption disorders. [1] Impaction involving a single tooth is a commonly observable finding. However, impaction of multiple teeth is an uncommon finding unless associated with some syndromes or systemic disorders. [1],[2] We report a case of multiple impacted permanent teeth in a non-syndromic patient.

An 18-year-old male was referred to department of oral and maxillofacial surgery with a chief complaint of malaligned teeth. On general physical examination, the patient was moderately built, healthy and did not exhibit any physical or skeletal abnormality and showed no signs of mental retardation. Intraoral examination revealed many of primary teeth like 53, 54, 55, and 63, 64, 65 in the maxillary arch and 73, 74, 75 and 83, 84, 85 in the mandibular arch [Figure 1] and [Figure 2] were retained. Permanent teeth like 11, 12, 16, 21, 22, 26 in the maxillary arch, 31, 32, 36, 41, 42, 46 in the mandibular arch were present. Based on panoramic [Figure 3] radiographic examinations, multiple impacted teeth belonging to the permanent dentition were found. Many teeth were horizontally impacted, rotated, and crowded in the mandibular and maxillary anterior region and were not in the eruption path. There were no cystic changes and the jaw bones showed normal trabecular pattern and density.{Figure 1}{Figure 2}{Figure 3}

Multiple impacted teeth itself is a rare finding and often found in association with syndromes such as cleidocranial dysplasia, Gardner's syndrome, Zimmerman-Laband syndrome and Noonan's syndrome. [2] In our case, apart from multiple impactions of permanent teeth, no other feature of any disorder was diagnosed. Multiple impacted teeth with no obvious etiology are a rare dental anomaly. In the literature, few reports are related to multiple impacted teeth with no known etiology. [2],[3] Delayed or arrested eruption is probably caused by diminished resorption of bone, primary teeth and due to presence of multiple supernumerary teeth. Conditions which cause lack of eruptive force may also lead to the same which could be general, endocrinal, neurogenic or mucosal or bone disorder. Conditions where we find retained teeth are: Hemifacial atrophy, hypopitutarism, hypothyroidism, cherubism, gingival fibromatosis and cleft palate. Lack of space or crowding of teeth in dental arches and rotation of tooth buds are some of the most common causes contributing to impaction. [4] In our case, it seems that lack of eruptive force in combination with rotation of tooth buds might have resulted in multiple impactions of teeth.
