The resorption of edentulous alveolar crests has been correlated to a variety of factors which may be briefly summarised as anatomic, metabolic, functional and prosthetic factors. With regard to functional factors, some researchers have found that some psychological aspects in edentulous subjects may be indicative of a parafunctional damaging habit leading to consequent alterations of the physical characteristics of forces applied to the bone. The aim of this study was to evaluate whether alveolar crest resorption in edentulous subjects was correlated to aspects of their psychological status, such as trait anxiety and the presence of psychosomatic symptoms. A group of 70 totally edentulous subjects were examined and trait anxiety and the presence of psychosomatic symptoms were evaluated. The orthopantomographies of the 70 subjects were then analysed in order to assess the degree of edentulous crest resorption. The present study showed the absence of statistically significant correlations between edentulous crest resorption and trait anxiety and between edentulous crest resorption and the presence of psychosomatic symptoms. These results appear to indicate that "anxious" subjects might not have parafunctional habits or that the latter play a minor role in the process of edentulous mandibular crest resorption.
无牙牙槽嵴的吸收与多种因素相关，这些因素可简要概括为解剖学、代谢、功能和修复因素。关于功能因素，一些研究人员发现，无牙患者的某些心理方面可能表明存在副功能损伤习惯，从而导致施加于骨骼的力的物理特性发生改变。本研究的目的是评估无牙患者的牙槽嵴吸收是否与其心理状态的某些方面相关，如特质焦虑和身心症状的存在。对一组70名全口无牙患者进行了检查，并评估了特质焦虑和身心症状的存在情况。然后对这70名患者的曲面断层片进行分析，以评估无牙嵴吸收的程度。本研究表明，无牙嵴吸收与特质焦虑之间以及无牙嵴吸收与身心症状的存在之间均不存在统计学上的显著相关性。这些结果似乎表明，“焦虑”患者可能没有副功能习惯，或者后者在无牙下颌嵴吸收过程中起次要作用。
