The replacement of lost teeth by fixed or removable dentures is very important in order to re-establish a correct phonetic and masticatory function and to restore a good aesthetical appearance to the patient. However when dental prosthesis, particularly the removable ones, become inadequate they may be responsible for a series of more or less dangerous lesions of the oral tissues. In this work a clinical and epidemiological study regarding the modality and the state of preservation of dentures in time has been carried out; moreover the possible presence of mucous membrane lesions in subjects with removable dentures has been investigated.
Seventy-height subjects with partial or totally removable dentures have been examined. After a general and stomatological anamnesis a thorough objective examination of the oral cavity was carried out in order to evaluate the removable denture state and the possible presence of mucous lesions correlated to them.
Women from sixty to seventy represent the greatest part of the subjects with removable dentures examined in this study. Nine years is the medium range of removable denture permanence in the mouth; in the greatest part of acrylic dentures the resin has never been replaced, they are inadequate and show a poor state of preservation. Twenty-height percent of the subjects examined report different troubles and in 46% of the cases the presence of dentures causes mucous lesions.
Since the greatest part of removable dentures examined in this study are inadequate and badly preserved, patients with removable dentures had better check them more often in order to allow the dentist to evaluate the functionality and the care of the dentures and to discover in time the possible presence of mucous lesions.
用固定或可摘义齿替换缺失牙对于重建正确的语音和咀嚼功能以及恢复患者良好的美观外观非常重要。然而,当假牙,特别是可摘假牙不合适时,它们可能会导致一系列或多或少对口腔组织有危险的病变。在这项工作中,进行了一项关于假牙随时间的保存方式和状态的临床和流行病学研究;此外,还调查了佩戴可摘假牙的受试者中黏膜病变的可能存在情况。
检查了78名佩戴部分或全口可摘假牙的受试者。在进行全面的口腔病史采集后,对口腔进行了全面的客观检查,以评估可摘假牙的状态以及与之相关的黏膜病变的可能存在情况。
60至70岁的女性占本研究中接受检查的可摘假牙受试者的最大比例。假牙在口腔中的平均使用年限为9年;在大多数丙烯酸假牙中,树脂从未更换过,它们不合适且保存状态不佳。28%的受检者报告有不同问题,在46%的病例中,假牙的存在导致黏膜病变。
由于本研究中检查的大多数可摘假牙不合适且保存不佳,佩戴可摘假牙的患者最好更频繁地检查假牙,以便牙医评估假牙的功能和保养情况,并及时发现可能存在的黏膜病变。
