Abstract

This article presents the first stage of treatment, respectively the orthodontic management of a non-syndromic, 13-year-old patient, with multiple and asymmetric missing teeth. The difficulty of the case was increased by the association of an impacted premolar and also by the loss, due to extended caries, of three of the first permanent molars. The patient came from a rural area, where access to dental treatment was limited. His parents realized too late that the child had significant damage to his permanent first molars, that he was no longer eating properly and that he had spaces between teeth. The uncertain outcome of endodontic treatment and prosthetic restoration at the level of first permanent molars and the additional costs made the parents decide, together with the dental practitioner, to extract teeth Nos. 16, 36 and 46. Giving the situation, the first phase treatment plan was represented by orthodontic closing of several maxillary spaces and the reduction of edentulous ridge in the mandible, followed by the maintenance of the space for two future implants, each one replacing the first molars in the third and fourth quadrants. Particularly for this growing patient, early intervention to treat and save as much from the permanent teeth as possible, to expose the impacted premolar, to level and align the teeth in order to obtain continuous dental arches and a good occlusion plane, and later to apply space maintainers that will be replaced by prosthetic restorations, represented an enormous step for long-term stability and proper functioning.

对一名患有先天性多恒牙缺失的非综合症患者的正畸治疗:一个罕见病例。
本文介绍了第一阶段的治疗情况,分别是对一名非综合症的 13 岁患者的正畸治疗,该患者有多颗不对称的牙齿缺失。该病例的难度增加了,因为患者的前臼齿被撞击,而且第一恒磨牙中有三颗因龋齿扩展而缺失。患者来自农村,牙科治疗条件有限。他的父母意识到孩子的第一恒磨牙严重受损、无法正常进食以及牙齿之间有空隙时已经为时已晚。牙髓治疗和第一恒磨牙修复的不确定结果以及额外的费用使父母与牙科医生一起决定拔掉第 16、36 和 46 号牙齿。鉴于这种情况,第一阶段的治疗方案是通过正畸关闭上颌的几个间隙,缩小下颌的缺牙嵴,然后为未来的两颗种植体保留空间,每颗种植体都替代第三和第四象限的第一颗臼齿。特别是对于这位成长中的患者来说,尽早治疗并尽可能多地保留恒牙,暴露受影响的前磨牙,将牙齿整齐排列以获得连续的牙弓和良好的咬合平面,以及随后应用空间维持器(将由修复体取代),对于长期稳定和正常功能来说是一个巨大的进步。
