研究目的:

本研究旨在评估具有重度牙周炎的患者行跨弓牙支持式固定义齿的长期成功率和稳定性,同时探讨导致跨弓固定义齿修复失败的危险因素,寻找可能的失败相关危险因素,并据此在术前进行风险评估,为临床提供一定的参考。  

Objectives of Study:

The aim of this study was to evaluate the long-term success rate and stability of cross-arch tooth-supported fixed dentures in patients with severe periodontitis, and to investigate the risk factors leading to cross-arch fixed denture repair failure, to find possible failure-related risk factors, and to perform risk assessment before surgery to provide some reference for clinical practice.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

(1)年龄≥18周岁 (2)在初始牙周治疗后的随访期间进行仍然进行牙周维护治疗的患者; (3)上或/和下颌行跨牙弓、牙支持式、固定义齿修复,且至少有6个连续的单元(基牙和桥体),完全由牙齿支撑,没有应力中断; (4)在接受修复前基牙数量足够(≥4颗)、双侧分布; (5)患者在初诊时诊断为III/IV期牙周炎,当患者未被明确诊断为III/IV期牙周炎时,则考虑被诊断为“严重牙周炎”、“晚期牙周炎”或/和牙槽骨吸收延伸到剩余牙齿根中1/3或根尖1/3; (6)所有患者在正式修复前进行了充分的牙周基础治疗。

Inclusion criteria

(1) Patients aged 18 years or older; (2) Patients who remained on periodontal maintenance therapy during the follow-up period after initial periodontal therapy; (3) Transarch, tooth support, fixed denture restorations were performed on the upper or/and lower jaw, and at least 6 consecutive units (abutments and pontics) were completely supported by the teeth without stress interruption; (4) Abutments were present in sufficient number (≥ 4) and distributed bilaterally before receiving restorations; (5) Patients were diagnosed with stage III/IV periodontitis at the time of initial diagnosis, and when patients were not definitely diagnosed with stage III/IV periodontitis, they were considered to be diagnosed with "severe periodontitis", "advanced periodontitis", or/and alveolar bone resorption extending into the root of the tooth or apical third; (6) All patients underwent adequate periodontal basic therapy before formal restorations.

排除标准:

(1)伴有夜磨牙、紧咬牙、咀嚼肌不适、关节疾病等症状者; (2)缺少患者基本信息及后续资料; (3)伴有未控制的免疫缺陷性疾病、传染性疾病、血液系统疾病及全身系统性疾病者等。 (4)其他研究者考虑后认为不适合该研究的患者等。

Exclusion criteria:

(1) Patients with night bruxism, clenching teeth, masticatory muscle discomfort, joint disease and other symptoms; (2) lack of basic information and subsequent data of patients; (3) Patients with uncontrolled immunodeficiency diseases, infectious diseases, blood system diseases and systemic diseases; (4) Patients considered unsuitable for the study by other investigators.
