Association of Occlusal Interferences with Overerupted Posterior Teeth.
J Pak Dent Assoc Jan ;22(1):19-22.

Objective: To determine the frequency of occlusal interferences associated with over-erupted posterior teeth and to detect an association between the presence of an occlusal interference and the presence and extent of overeruption of unopposed posterior teeth. Methodology: The methodology used has already been given in a previously published article in Pakistan Oral and Dental Journal (2012; 32(1):159-63). Results: Twenty four (46.15%) subjects had at least one occlusal interference in one of their unopposed tooth. Protrusive interference was most commonly observed (n=16, 37%) followed by interferences in retruded contact position (n=12, 27%), working (n=9, 19%) and non-working (n=8, 17%) positions. The association of presence and extent of over-eruption and presence of occlusal interference was not significant. (p>0.005) Conclusion: Majority of the occlusal interferences were encountered in protrusive excursions followed by retruded contact position. There was no statistical association between presence of occlusal interferences and the presence and extent of over-eruption in unopposed posterior teeth.
