The article presents aspects of crown and root morphology of the superior wisdom teeth, aiming to several parameters: size, shape crown and occlusal surface, number, topography and orientation of the roots in order to determine which the most common morphological types are. For this purpose, the upper wisdom teeth were collected. According to studies, the dominant form of the dental crown is parallelepipedic, the rectangular or parallelogram shape of the occlusal surface has large mesial and distal-oriented sides. The positive occlusal forms are generally poorly demarcated; cusps are less tall and rarely individualized. In half of the cases, the root is unique, voluminous, straight or with a curved distal tip.
本文介绍了上颌智齿冠部和根部的形态特征，旨在研究几个参数：大小、冠部形状和咬合面、牙根数量、位置及方向，以确定最常见的形态类型。为此，收集了上颌智齿。根据研究，牙冠的主要形态为平行六面体，咬合面呈长方形或平行四边形，其近中侧和远中侧较大。正向咬合形态通常界限不清；牙尖较低且很少分化。在半数病例中，牙根单一、粗大，呈直形或远端弯曲。
