上颌第三磨牙解剖形态的研究进展

The research progress of maxillary third molar anatomical morphology

第三磨牙作为人类最晚萌出的恒牙,因其多为阻生牙、废用牙,在临床治疗中一直以拔除为主。但随着口腔医学的发展,上颌第三磨牙的临床治疗价值逐渐得到认可,并在口腔修复学、口腔正畸学、口腔种植学等领域有所应用。本文就近年来对第三磨牙的牙冠、牙根、根管、根尖孔形态等研究做一综述,以期为相关研究和临床治疗提供帮助。

Third molars, late-eruption permanent teeth in humans, have commonly been extracted in clinical treatments. However, with the development of oral medicine, the value of maxillary third molars in clinical treatments, as well as in oral prosthetics, orthodontics, and oral implant applications, has gradually become recognized. This paper summarizes the research on the morphology of the crown, root, root canal and root tip of the maxillary third molar in a review to facilitate related research and clinical treatments.
