PREMISES AND AIM: The study wants to reveal the general and local clinical aspects, which may accompany the completely edentulous mouth and create difficulties in treatment.
The clinical and statistical study was carried out on 40 edentulous patients; we analyzed general aspects (the present medical status, the patient's medication and its effects) and local aspects (the etiology, the type of previous denture treatment, the type and number of denture's repairs, the extent of the residual ridge resorption, the relationship between residual ridges), the total difficulty of the treatment.
80% of the edentulous patients suffered from general diseases, more frequent from cardiovascular, digestive, metabolic, renal, rheumatic diseases. 73% of the edentulous patients received daily medication, which generated in 30% of cases a decrease of the saliva volume. The demand for prosthetic treatment was greater for the recent edentulous patients (less then 1-2 years of edentulousness) or for those who lost their teeth more then 6 years ago. The majority of patients over 70 years are completely bimaxillary edentulous patients, 68% of them had previous bimaxillary dentures. We found the bone resorption moderate (50% of cases) and severe (33% of patients), the relationship of the residual ridges inverse in the anterior and posterior zones (60% of patients) and normal in the anterior zone and inverse in the posterior zone (28%). The difficulty of the treatment was frequently 3Pd degree for the maxilla and 4t' degree for the mandible (the maximum degree of difficulty).
The completely edentulous patient presents a number of general and local modifications, which increase the difficulty of the treatment, demand supplementary therapeutic procedures, and increase the total cost. The modifications of the oral structures demand specific therapeutic procedures, and in some cases the frequent renewal or adaptation of dentures (every 3-5 years); all those costs must be took over by the insurance company, because of their social status (pensioners).
前提与目的：本研究旨在揭示全口无牙颌可能伴随的全身和局部临床情况，以及这些情况给治疗带来的困难。
对40例无牙颌患者进行了临床和统计学研究；我们分析了全身情况（当前的医疗状况、患者的用药及其效果）和局部情况（病因、先前义齿治疗的类型、义齿修复的类型和次数、剩余牙槽嵴吸收的程度、剩余牙槽嵴之间的关系）以及治疗的总体难度。
80%的无牙颌患者患有全身性疾病，其中心血管、消化、代谢、肾脏、风湿性疾病更为常见。73%的无牙颌患者每日用药，其中30%的病例出现唾液量减少。近期无牙颌患者（无牙时间少于1 - 2年）或6年前以上失牙的患者对修复治疗的需求更大。70岁以上的患者大多数为全口无牙患者，其中68%曾佩戴过全口义齿。我们发现骨吸收为中度（50%的病例）和重度（33%的患者），剩余牙槽嵴在前部和后部区域呈反向关系（60%的患者），前部区域正常而后部区域呈反向关系（28%）。上颌治疗难度常为3Pd级，下颌为4t'级（最大难度级别）。
全口无牙颌患者存在一些全身和局部改变，这些改变增加了治疗难度，需要额外的治疗程序，并增加了总成本。口腔结构的改变需要特定的治疗程序，在某些情况下需要频繁更换或调整义齿（每3 - 5年）；由于这些患者的社会身份（退休人员），所有这些费用必须由保险公司承担。
