Dental agenesis is a condition in which the absence of teeth causes debilitating problems, primarily in speech, mastication, and esthetics. The optimal removable prosthetic management for the condition is unclear.
The purpose of this systematic review was to evaluate the spectrum of removable prosthetic techniques with regard to the type of edentulism and to provide clinical guidance for practicing dentists.
An electronic and manual search was conducted in the PubMed, Scopus, and Google Scholar databases. Publications of case reports and series written in English without data restrictions that reported on removable prosthodontic management of patients with oligodontia, hypodontia, or anodontia were included.
A total of 59 articles comprising 83 case reports were analyzed. In patients with anodontia, the most common treatment option was an acrylic resin complete denture. Hypodontia and oligodontia were commonly managed by using either a partial denture or overdenture. Irreversible hydrocolloid or alginate was the most accepted material for the preliminary impressions and elastomeric materials for definitive impressions. The tooth arrangements were modified to simulate natural dentition and improve esthetics. Modifications of conventional acrylic resin dentures have been proposed for improved denture adaptation. Good retention is essential to the long-term success of prosthetic treatment and may be achieved with a denture reline or with retention clasps. The active growth of the patients means constant maintenance, including denture renewals or repairs, emphasizing the need for long-term follow-up care.
Prosthodontic rehabilitation at an early age has been shown to significantly impact the overall quality of life for a child with tooth agenesis.
牙齿先天缺失是一种因牙齿缺失而导致使人衰弱的问题的病症,主要影响言语、咀嚼和美观。对于这种病症的最佳可摘义齿修复治疗方法尚不清楚。
本系统评价的目的是评估针对无牙情况的可摘义齿修复技术范围,并为执业牙医提供临床指导。
在PubMed、Scopus和谷歌学术数据库中进行了电子和人工检索。纳入了以英文撰写的、无数据限制的病例报告和系列文章,这些文章报道了少牙、缺牙或无牙患者的可摘义齿修复治疗情况。
共分析了59篇文章,包括83例病例报告。对于无牙患者,最常见的治疗选择是丙烯酸树脂全口义齿。少牙和缺牙情况通常通过使用局部义齿或覆盖义齿进行处理。不可逆水胶体或藻酸盐是最常用的初印模材料,弹性体材料用于终印模。牙齿排列经过调整以模拟天然牙列并改善美观。有人提出对传统丙烯酸树脂义齿进行改进以提高义齿贴合度。良好的固位对于修复治疗的长期成功至关重要,可通过义齿重衬或固位卡环实现。患者的生长发育意味着需要持续维护,包括义齿更新或修复,这强调了长期随访护理的必要性。
已证明早期进行义齿修复对牙齿先天缺失患儿的整体生活质量有显著影响。
