口腔修复患者牙体缺损、牙列缺失和牙列缺损的临床特点研究

Research of Clinical Characteristics of Tooth Defect, Dentition Loss and Dentition Defect in Patients With Oral Repair

目的分析研讨口腔修复患者牙体缺损、牙列缺失和牙列缺损的临床特点。方法用随机数字法从我院2011年3月—2017年2月期间收治的口腔修复患者中,抽取896例纳入到讨论中,回顾分析其病历资料,不同年龄、不同性别的患者在牙列缺损、牙列缺失、牙体缺损等方面的差异,并分析。结果 896例口腔修复患者中,男性牙列缺失、牙列缺损、牙体缺损共450例(50.22%),女性共446例(49.78%),性别比率对比χ~2=0.0039,P=0.9503。上颌牙列缺损和牙列缺失共446例(49.78%),下颌牙列缺损和牙列缺失共348例(38.83%),上下颌牙列缺损和牙列缺失共75例(8.37%),牙列缺失和缺损在不同部位分布存在差异P<0.05。对比不同年龄阶段牙齿缺损分布比,<30岁人群低于30~60岁人群、>60岁人群,且P<0.05;30~60岁人群低于>60岁人群,且P<0.05。患者口腔修复状况铸造支架义齿(54.02%)位居首位,其次为金属烤瓷联合全冠(24.67%)。结论口腔修复患者牙体缺损、牙列缺损、牙列缺失和性别、临床修复状况无关,与患者年龄存在关系,且修复过程中需遵循耐用、美观的原则。

Objective To analyze and discuss the clinical characteristics of tooth defect, dentition loss and dentition defect in patients with oral repair. Methods 896 cases of patients with oral repair and who accepted treatments in our hospital from March 2011 to February 2017 were included into discussion, and its medical records were retrospective analyzed. Then, the difference of dentition defect, dentition loss and tooth body defect of patients with different nationality, age and sex were compared and analyzed. Results In 896 cases of dental prosthesis, there were 450 cases （50.22%） of male dentition defect, dentition defect and dental defect, and 446 cases （49.78%） of female patients, and the sex ratio were compared, χ2=0.0039, P=0.9503.There were 446 cases （49.78%） of maxillary teeth defect and dentition missing. There were 348 cases （38.83%） of mandibular defect and dentition missing.75 cases （8.37%） of maxillary and mandibular defect and dentition missing. There was difference in distribution of defects and defects in different parts of the dentition P 〈 0.05. The distribution ratio of dental defects in different age stages was compared, and the people aged 〈30 were lower than 30-60 years old , 〉 60 years old , and P 〈 0.05; The 30-60 year old population was lower than the 〉 60 age group and P 〈 0.05.The patients with dental prosthesis （54.02%） were in the frst place. The second was the metal porcelain fused to the whole crown （24.67%）. Conclusion The dental defect, dentition defect and dentition deletion in patients with oral repair was not related to the status of sex and clinical repair, and it is related to the age of the patient, and the principle of durability and beauty should be followed in the process of repair.
