Lithium disilicate glass-ceramic (LDC) restorations exhibit microorganism infiltration, recurrent caries, pulpal lesions, periodontal inflammation, and cement exposure to the oral environment over time. All these factors lead to restoration failure. This systematic review aimed to investigate the clinical outcomes of LDC full-coverage crowns (FCC) in permanent teeth compared with those of other full-coverage restoration materials.
MATERIALS & METHODS: Search strategies were developed for four databases: Web of Science, OVID, PubMed, and Scopus. Data extraction and quality appraisals were performed by two independent reviewers. Data on the presence of caries, post-operative sensitivity, and periodontal changes were extracted from the included clinical studies. In addition to the outcome measures, data on the sample size, study groups, method of restoration fabrication, type of impression, and type of abutment were recorded.
We retrieved 3989 records for the title and abstract screening. Of these, 19 clinical studies met the inclusion criteria. The overall quality of the included studies indicates a low risk of bias. Most studies reported no pulpal involvement, recurrent caries, or post-operative sensitivity and presented a favorable periodontal response after the cementation of LDC-FCC during different follow-up periods.
Based on the endodontic and periodontic clinical responses of natural tooth abutments and their supporting periodontium, LDC-FCC can be considered a clinically successful restorative option.
随着时间的推移，二硅酸锂玻璃陶瓷（LDC）修复体存在微生物渗入、继发龋、牙髓病变、牙周炎症以及粘结剂暴露于口腔环境等问题。所有这些因素都会导致修复失败。本系统评价旨在研究LDC全冠（FCC）修复恒牙与其他全冠修复材料相比的临床效果。
针对四个数据库制定检索策略：科学网、OVID、PubMed和Scopus。由两名独立的评审员进行数据提取和质量评估。从纳入的临床研究中提取有关龋病、术后敏感性和牙周变化的数据。除了结局指标外，还记录了样本量、研究组、修复体制作方法、印模类型和基牙类型等数据。
我们检索到3989条标题和摘要记录。其中，19项临床研究符合纳入标准。纳入研究的总体质量表明偏倚风险较低。大多数研究报告无牙髓受累、继发龋或术后敏感性，并且在不同随访期LDC-FCC粘结后牙周反应良好。
基于天然牙基牙及其支持牙周组织的牙髓和牙周临床反应，LDC-FCC可被认为是一种临床上成功的修复选择。
