A 5-year-old Caucasian male presented with early loss of multiple deciduous teeth. All the characteristics were consistent with the diagnosis of regional odontodysplasia (ROD). Significant initial findings included premature loss of multiple primary mandibular teeth and some malformed permanent teeth. The affected teeth showed hypoplastic enamel and dentin, short roots, and wide pulp chambers, and were localized in the mandibular dentition. Treatment objectives for this patient were to provide improved esthetics, restored chewing function, and space maintenance by the construction of a temporary prosthetic restoration. However, with limited tooth support and an unusual occlusal pattern, it is difficult to obtain satisfactory retention and esthetics with traditional prosthetic techniques. In this article we introduce an alternative method for fabricating a custom removable denture and discuss the prognosis of the malformed permanent dentition and further treatment plan.
一名5岁的白种男性出现多颗乳牙过早缺失。所有特征均与局部牙发育异常(ROD)的诊断相符。显著的初始表现包括多颗下颌乳牙过早缺失以及一些恒牙发育畸形。患牙表现为釉质和牙本质发育不全、牙根短、髓腔宽大,且局限于下颌牙列。该患者的治疗目标是通过制作临时修复体来改善美观、恢复咀嚼功能并维持间隙。然而,由于牙齿支持有限且咬合模式异常,采用传统修复技术难以获得满意的固位和美观效果。在本文中,我们介绍一种制作定制可摘义齿的替代方法,并讨论发育畸形恒牙列的预后及进一步的治疗方案。
