文题释义:
全口义齿重衬:是在全口义齿的组织面上加上一层塑料,使其充满牙槽嵴及周围组织被吸收部位的间隙,使基托组织面于周围组织密合,增加义齿的固位力。适用于全口义齿戴用一段时间后,由于剩余牙槽嵴吸收等原因,导致全口义齿固位稳定不佳。义齿折断修理后如基托不密合也需要进行重衬。
骨转化标志物:是能够在血液和尿液及其他人体分泌物检测出来的骨组织代谢产物,可反映骨吸收和骨形成状况。其与骨密度联合监测有助于早期了解骨转换的动态变化,对骨转换平衡状态的评估、骨代谢疾病的鉴别诊断、抗骨质疏松治疗疗效评价等方面有重要意义。
 
背景:患有骨质疏松的老年无牙颌患者剩余牙槽嵴往往形态不佳,修复难度较大,目前尚无相应参考指标来反映此类患者剩余牙槽嵴吸收的情况和指示重衬等临床处理的频率。
目的:分析患有骨质疏松的老年无牙颌患者全口义齿重衬频率与血清中骨钙素和Ⅰ型胶原羧基端交联肽两种骨转化标志物水平之间的相关性,以期为临床全口义齿修复提供参考。
方法:按照纳入标准随机选取50例已行全口义齿修复并患有骨质疏松的老年无牙颌患者,对其进行相关问卷调查并查阅病史确定义齿重衬频率,同时采集患者空腹静脉血,采用电化学发光免疫法测量血清中骨钙素与Ⅰ型胶原羧基端交联肽的水平,通过Pearson相关性检验的统计学方法来分析重衬频率与骨钙素和Ⅰ型胶原羧基端交联肽之间的关系。
结果与结论:患者的义齿重衬频率与血清中骨钙素水平之间有显著的正相关关系(r=0.517,P < 0.01),而其与血清中Ⅰ型胶原羧基端交联肽水平并未观察到显著相关性(r=0.278,P=0.051 > 0.05),但二者有着相近的变化趋势。说明对于患有骨质疏松的老年无牙颌患者来说,检测血清中骨转化标志物水平有助于全口义齿修复疗效预后的评估和诊疗决策的制定。

Abstract:

BACKGROUND: The residual alveolar ridge in edentulous patients with osteoporosis always presents with a poor shape, which increases the difficulty in complete denture restoration. Until now, there are no predictors for residual alveolar ridge resorption or guidelines on the frequency of denture relines.
OBJECTIVE: To investigate the correlation between the frequency of complete denture relines and serum bone turnover markers, osteocalcin (OC) and cross-linked carboxy-terminal telopeptide of type I collagen (CTX), in elderly edentulous patients with osteoporosis, in order to provide reference for complete denture repair.
METHODS: According to inclusion criteria, 50 elderly edentulous patients with osteoporosis who had complete dentures were recruited in the study randomly. The frequency of complete denture relines was surveyed by related questionnaire and medical record, and the serum OC and CTX levels were detected by electrochemiluminescence immunoassay. Related data were analyzed statistically via Pearson correlation analysis.
RESULTS AND CONCLUSION: It showed a strong positive correlation between the frequency of complete denture relines and the serum OC level (r=0.517, P < 0.01). No significant correlation between relines frequency and the serum CTX level was observed (r=0.278, P=0.051 > 0.05), but it showed a similar tendency between them. These findings indicate that to detect the levels of serum bone turnover markers may be conducive to evaluating curative effect of complete dentures in elderly edentulous patients with osteoporosis as well as to making subsequent diagnostic and therapeutic strategies.
