Frequency of overeruption in unopposed posterior teeth

ABSTRACT

The objective of the study was to determine the frequency and extent of over eruption in unopposed posterior teeth. The study was conducted in the Department of Prosthodontics, Lahore Medical and Dental College, Lahore. Fifty sites of unopposed posterior teeth were included in the study. Broadrick flag technique was used for the generation of broadrick occlusal curve. The measurement of over eruption of the unopposed posterior tooth was measured from the generated curve to the tip of most occlusally projecting cusp by a vernier caliper. Forty seven [90%] of the subjects and sixty teeth [83.3%] out of seventy two had some degree of over eruption. It was concluded that unopposed posterior teeth lead to over eruption of antagonists with clinical and statistical significance [83.3%]
