Abstract

Purpose: This study performed a systematic review to assess the biomechanical behavior of all-ceramic endowcrowns fabricated using computer-aided design and computer-aided manufacturing (CAD/CAM) for the restoration of endodontically treated teeth.

Study selection: Three electronic databases (PubMed, Web of Science, and Scopus) were searched by operators specializing in health sciences databases searches to answer the following focused question based on the Population, Intervention, Comparison, Outcome (PICO) format: "Whether all-ceramic CAD/CAM endocrowns (Intervention) used to restore human endodontically treated teeth (Population) exhibit superior fracture resistance (Outcome) compared to non-CAD/CAM all-ceramic or non-ceramic endocrowns (Comparison)." The methodological quality assessment was performed using previously conducted systematic reviews of in vitro studies. The outcomes were expressed as the mean ± the standard deviation (SD).

Results: Seventeen in vitro studies were included. The materials used in these studies were lithium disilicate glass-ceramic, polymer-infiltrated ceramic, zirconia-reinforced lithium silicate glass-ceramic, resin/hybrid nanoceramics, zirconia-reinforced lithium silicate ceramics, and feldspathic ceramic. The fracture resistance of endocrowns using different ceramics varied as follows: (i) IPS e.max CAD (2863.62 ± 51.47 N), (ii) Vita Enamic (1952 ± 378 N), (iii) Vita Suprinity (1859 ± 588 N), (iv) Cerasmart (1981 ± 169.5 N), (v) LAVA Ultimate (2484 ± 464 N), (vi) Celtra Duo (1618.30 ± 585.00 N), and (vii) Cerec Blocs (236.29 ± 32.12 N).

Conclusions: CAD/CAM all-ceramic endocrowns can withstand occlusal forces in the posterior region. All-ceramic endocrowns improve the fracture strength of endodontically treated teeth. Lithium disilicate crowns were commonly and successfully used in the included studies. More in vitro investigations that implement uniformity in material and measurement approaches are required to strengthen the evidence currently available in the literature regarding the durability of all-ceramic endocrowns.

使用 CAD/CAM 制作的全陶瓷内冠的生物力学行为：系统综述。

目的：本研究对使用计算机辅助设计和计算机辅助制造（CAD/CAM）制作的全瓷冠修复牙髓治疗后牙齿的生物力学行为进行了系统性回顾评估：由专门从事健康科学数据库检索的操作人员对三个电子数据库（PubMed、Web of Science 和 Scopus）进行了检索，以回答以下基于人群、干预、比较、结果（PICO）格式的重点问题："与非 CAD/CAM 全陶瓷或非陶瓷内冠（比较）相比，用于修复人类牙髓治疗牙齿（人群）的全陶瓷 CAD/CAM 内冠（干预）是否表现出更优越的抗折性（结果）"。方法学质量评估采用的是之前进行的体外研究系统综述。结果以平均值±标准差（SD）表示：结果：共纳入 17 项体外研究。这些研究使用的材料包括二硅酸锂玻璃陶瓷、聚合物渗入陶瓷、氧化锆增强硅酸锂玻璃陶瓷、树脂/混合纳米陶瓷、氧化锆增强硅酸锂陶瓷和长石陶瓷。使用不同陶瓷的内冠的抗断裂性变化如下：(i) IPS e.max CAD (2863.62 ± 51.47 N)，(ii) Vita Enamic (1952 ± 378 N)，(iii) Vita Suprinity (1859 ± 588 N)，(iv) Cerasmart (1981 ± 169.5 N)，(v) LAVA Ultimate (2484 ± 464 N)，(vi) Celtra Duo (1618.30 ± 585.00 N)，(vii) Cerec Blocs (236.29 ± 32.12 N)：CAD/CAM全瓷内冠可以承受后牙区域的咬合力。结论：CAD/CAM 全瓷内冠可承受后牙区的咬合力，全瓷内冠可提高牙髓治疗后牙齿的抗折强度。在纳入的研究中，二硅酸锂冠被普遍成功使用。要加强目前文献中关于全瓷内冠耐久性的证据，还需要进行更多的体外研究，统一材料和测量方法。

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.
