摘要

目的评估微创半永久性咬合聚甲基丙烯酸甲酯(PMMA)嵌体/veneers在既往颞下颌关节紊乱症(TMD)患者中的存活率:本系列病例是通过连续招募患者进行随访评估而设计的。所有符合这种修复适应症的患者均由同一临床医生使用相同的粘接方法进行治疗。研究包括 22 名患者(3 男/19 女),平均年龄为 50.7 [11.6]岁。对照组在最初 4 周内进行了随访(随后根据需要进行了随访)。失败标准包括断裂、崩裂和固位丧失。根据 Kaplan-Meier 分析法确定存活率:共纳入 328 个半永久性咬合/咬合贴面(142 个上颌牙/186 个下颌牙)。在 180 天后开始的后续治疗中,几乎 80% 的修复体都已就位并发挥功能;失败主要发生在最初的 3 到 6 个月内,但都证明是可以修复的。根据患者的优先顺序,修复体会陆续更换,超过 65% 的修复体在 360 天内没有出现修复或任何更新需求:在这项研究的局限性范围内,PMMA 制成的咬合贴面的存活率很高,可以通过永久性修复体对相关牙齿进行连续治疗,同时保留修复后的垂直尺寸。对于牙齿磨损严重并有TMD病史的患者,使用PMMA咬合贴面/veneers进行半永久性修复治疗似乎是一个值得注意的选择。

Prospective case series study on the survival rates of occlusal polymethyl methacrylate veneers as a semipermanent therapy in patients with severe pathologic tooth wear.

Objectives: To evaluate the survival rate of minimally invasive semipermanent occlusal polymethyl methacrylate (PMMA) onlays/veneers in previous temporomandibular disorder (TMD) patients with severe tooth wear and with a loss of vertical dimension after up to 7 years.

Method and materials: This case series was designed as a follow-up evaluation with consecutive patient recruitment. All patients bearing the indication for this kind of rehabilitation were treated by the same clinician using the same adhesive methodology. The study included 22 patients (3 men/19 women), with a mean ± SD age of 50.7 ± 11.6 years. Controls followed within the first 4 weeks (and subsequently as required). Failure criteria included damage by fracture, chipping, and retention loss. Survival rates were determined based on the Kaplan-Meier analysis.

Results: 328 semipermanent occlusal/incisal veneers were included (142 maxillary/186 mandibular teeth). Almost 80% of the restorations were in place and in function when starting the follow-up treatment after 180 days; failures predominantly occurred within the first 3 to 6 months but proved reparable. Depending on the patients' priorities, scheduled replacements followed successively, and more than 65% did not show repair or any renewal needs for more than 360 days.

Conclusion: Within the limitations of this study the survival rates of occlusal veneers made of PMMA were sufficiently high to allow for consecutive treatment of the respective teeth by means of permanent restorations while preserving the restored vertical dimension. In patients with severe tooth wear and a TMD history, semipermanent restorative therapy with occlusal PMMA onlays/veneers would seem a noteworthy option.

期刊介绍: QI has a new contemporary design but continues its time-honored tradition of serving the needs of the general practitioner with clinically relevant articles that are scientifically based. Dr Eli Eliav and his editorial board are dedicated to practitioners worldwide through the presentation of high-level research, useful clinical procedures, and educational short case reports and clinical notes. Rigorous but timely manuscript review is the first order of business in their quest to publish a high-quality selection of articles in the multiple specialties and disciplines that encompass dentistry.
