Abstract

Background

Implant-supported prostheses frequently face both mechanical and biological challenges. Although various techniques and principles are employed to manage excessive loads, occlusal contacts often change within 6 months of placement.

Objective

This review aims to analyse relevant studies to evaluate the changes in occlusal contacts that occur following the placement of superstructures in implant-supported prostheses.

Methods

The protocol was designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) and registered with the International Prospective Register of Systematic Reviews. Studies were included if their outcomes addressed stress distribution, occlusal force, occlusal contact, occlusal scheme or changes in occlusal time. Non-English articles, case reports, animal experiments, systematic reviews and literature reviews were excluded.

Results

A total of 1867 articles were retrieved through database searches, along with an additional 43 articles identified through manual searches, of which 416 were duplicates. After screening the titles and abstracts, 1367 articles were excluded, and 12 were deemed non-retrievable. The full texts of the remaining 85 articles were independently reviewed by two authors for eligibility, resulting in the exclusion of 77 articles based on the inclusion criteria. Ultimately, eight articles were included in the review.

Conclusion

Implant-supported crowns gradually approach or surpass the load of natural teeth over time, as evidenced by increased occlusal force, larger contact areas and longer occlusion durations. These findings highlight the need for more accurate and advanced measurement techniques to better understand and manage the long-term changes in occlusion associated with implant-supported crowns.

种植体支持的固定义齿咬合接触改变：系统综述。

背景：种植体支持的假体经常面临力学和生物学的挑战。虽然采用了各种技术和原则来控制过度负荷，但咬合接触通常在放置的6个月内发生变化。目的：本综述旨在分析相关研究，以评估种植义齿放置上部结构后咬合接触的变化。方法：该方案按照系统评价和荟萃分析方案的首选报告项目（PRISMA-P）设计，并在国际前瞻性系统评价登记册上注册。如果研究结果涉及应力分布、咬合力、咬合接触、咬合方案或咬合时间的变化，则纳入研究。非英文文章、病例报告、动物实验、系统综述和文献综述被排除在外。结果：通过数据库检索共检索到1867篇文章，另外通过人工检索确定了43篇文章，其中416篇是重复的。在筛选标题和摘要后，1367篇文章被排除在外，12篇被认为不可检索。其余85篇文章的全文由两位作者独立审查是否合格，根据纳入标准排除了77篇文章。最终，8篇文章被纳入综述。结论：随着时间的推移，种植体支撑冠逐渐接近或超过天然牙的负荷，表现为咬合力增加，接触面积增大，咬合持续时间延长。这些发现强调需要更精确和先进的测量技术来更好地理解和管理与种植支撑冠相关的长期咬合变化。试验注册：PROSPERO: CRD42024527043。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
