BEAM PROSTHESES ON ATTACHMENTS IN ORTHOPEDIC DENTISTRY: CLINICAL AND FUNCTIONAL ASPECTS AND APPLICATION PROSPECTS

Girder prostheses on attachments represent one of the most functionally sound removable prosthetics designs in orthopedic dentistry. This type of prosthesis combines the advantages of splinting support elements, uniform distribution of chewing load and a high degree of retention, which is especially important in the treatment of patients with partial and complete secondary adentia, complicated by a decrease in periodontal stability. The article discusses the design features of beam prostheses on attachments, the biomechanical principles of their functioning, indications and contraindications for use, as well as clinical and functional advantages over traditional clamp fixation systems. Special attention is paid to the issues of long-term stability of orthopedic structures and the influence of beam attachments on the condition of prosthetic bed tissues.附着体式梁状义齿（Girder prostheses on attachments）是口腔矫形牙科（orthopedic dentistry）中功能性能最为完善的可摘义齿设计方案之一。此类义齿兼具夹板式支持结构的优势，可实现咀嚼负荷的均匀分布，且具备极高的固位能力，这一点在治疗伴牙周稳定性下降的部分性及完全性继发性牙列缺失患者时尤为关键。本文探讨了附着体式梁状义齿的设计特征、发挥功能的生物力学原理、临床适应证与禁忌证，以及相较于传统卡环固位系统的临床与功能优势。此外，本文重点关注了口腔矫形修复体的长期稳定性，以及附着体式梁状义齿对义齿承托区组织状态的影响。
