Abstract

Purpose: This observational retrospective clinical study aimed to investigate the survival and success rates of partial indirect lithium disilicate restorations with margins extending above or beyond the cementoenamel junction (CEJ).

Methods: The study included patients who underwent partial indirect lithium disilicate restorations with immediate dentin sealing (IDS) between January 2008 and October 2018. All the restorations were placed in a single general dental practice following a standardized protocol. The impact of various predictive variables on the survival rates was assessed. Moreover, modified United States Public Health Service (USPHS) criteria were used to evaluate the survival quality.

Results: Totally 1146 partial indirect lithium disilicate restorations in 260 patients were evaluated over an average period of 7.5 years. The cumulative survival and success rates were 97.3% and 95.3%, respectively. Margins extending beyond the cemento-enamel junction did not increase the risk of success or survival failure (P > 0.05). Patients with a high risk of caries, male sex, or non-vital teeth had a significantly higher risk of restoration failure (P < 0.05). Restorations with longer clinical service times exhibited marginally lower clinical quality (P < 0.001).

Conclusions: Partial indirect glass-ceramic restorations demonstrated survival and success rates of 97.3% and 95.3%, respectively, over an extended period. However, a higher risk of restoration failure existed in patients with a high caries risk for (pre)molars that had undergone endodontic treatment and in males. In terms of the risk of success or survival failure, comparable results were obtained for the positions of the restoration margin in relation to the cemento-enamel junction.

边缘超出或高于骨水泥-釉质交界处的部分玻璃陶瓷后修复体：一项观察性回顾临床研究

目的：本观察性回顾临床研究旨在探讨边缘延伸至牙本质釉质交界处（CEJ）以上或以外的部分间接二硅酸锂修复体的存活率和成功率：研究对象包括2008年1月至2018年10月期间接受部分间接二硅酸锂修复体并进行即刻牙本质封闭（IDS）的患者。所有修复体都是在一家全科牙科诊所按照标准化方案植入的。评估了各种预测变量对存活率的影响。此外，还采用了美国公共卫生署（USPHS）的修订标准来评估存活质量：共对 260 名患者的 1146 例间接二硅酸锂部分修复体进行了评估，平均时间为 7.5 年。累计存活率和成功率分别为 97.3% 和 95.3%。边缘超出骨水泥-釉质交界处不会增加成功或失败的风险（P >0.05）。龋齿风险高、男性或非活牙患者的修复失败风险明显更高（P <0.05）。临床服务时间较长的修复体的临床质量略低（P< 0.001）：部分间接玻璃陶瓷修复体在较长时间内的存活率和成功率分别为 97.3% 和 95.3%。然而，对于曾接受过牙髓治疗的（前）磨牙龋坏风险较高的患者和男性而言，修复失败的风险较高。就修复成功或失败的风险而言，修复体边缘与牙本质-釉质交界处的位置具有可比性。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function. The most-targeted topics: 1) Clinical Epidemiology and Prosthodontics 2) Fixed/Removable Prosthodontics 3) Oral Implantology 4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
