90例无牙颌患者的临床调查分析

目的 研究无牙颌患者牙槽嵴的条件。方法 对我院普通门诊中收集的90例(男47例、女43例)无牙颌患者的临床资料进行分析。结果 90例患者中50岁以下牙槽嵴条件高：中：低=l：l：0;51-60岁牙槽嵴条件高：中：低=l：1．2：0．2;61-70岁牙槽嵴条件高：中：低=l：3.4：0．8;7l-80岁牙槽嵴条件高：中：低=l：2．3：09;8l-90岁牙槽嵴条件高：中：低=l：1．3：0．3．上下牙槽嵴条件均差者均为牙周病病人。统计分析结果表明无牙颌患者性别之间无显著性差异,但不同年龄段之间有显著性差异,以6l-70岁年龄段就诊的无牙颌患者最多,其次为7l-80岁。牙槽嵴条件之间也有显著性差异,以牙槽嵴条件中等者最多,其次为牙槽嵴条件较好者。此外。上下颌牙槽嵴条件有显著性差异,下颌牙槽嵴条件明显差于上颌;性别与牙槽嵴条件无显著性差异：不同年龄段患者牙槽嵴条件无显著性差异。结论 要求修复的无牙颌患者的年龄主要集中在60-70岁年龄段,其中牙槽嵴条件中等者占大多数,牙槽嵴条件下颌明显差于上颌。随着年龄的增长。牙槽嵴条件逐步变差。

Clinical investigation about 90 edentulous cases and exploration of therapy for the low alveolar bridge

Objective To study the situation of alveolar bridge for the causes of edentulousness. Methods 90 clinical edentulous cases were investigated. The relative facts such as sex,age and the situation" of alveolar bridge etc were Studied. Results (1)There were 47 male cases among the 90 cases, for a percentage of 52.2%; 43 female cases, for a percentage of 42.8 %. The distribution of ages was 4.4% under 50 years of age(4cases), 12.2% between 51~60 years of age(l leases), 54.4% between 61~70 years of age(49cases), 23.3% between 71~80 years of age(21cases), 5.5% between 81~90 years of age (5cases). There was one female case under 50 years of age, there was no male case between 81-90 years of age.For the condition of alveolar bridge, there were 31 cases in high lever at maxilla (34%), 15 cases at mandible (16%); There were 54 cases in medial lever at maxilla (60%), 53 cases at mandible (58%); There were 5 cases in low lever at maxilla (5%), 22 cases in mandible (24%). At different lever of alveolar bridge, There were high : medial: low equal 1:1:0 under 50 years of age, 1:1.2:0.2 between 51-60 years of age, 1:3.4:0.8 between 61-70 years oi' age, l:2.3:0.9 between 71-80 years of age, 1:1.3:0.3 between 81-90 years of age. All of the patients with low alveolar bridge both in maxilla and mandible had periodontitis. There was no statistic difference of edentulous cases in sex . There was significant difference between difference age. For the alveolar bridge condition, there was significant difference between maxilla and mandible and between different lever. The mandible condition was much worse than maxilla. The medial lever of alveolar ridge was most. Conclusion The age of edentulous cases was focused on 60-70 years of age. Most of them were at the medial lever, the mandible alveolar bridge condition was much worse than maxilla. The number of edentulous cases during 61-70 years of age was the large.st. There was not significant difference about alveolar bridge condition at different ages and different sex.
