Severely atrophic ridges provide decreased retention, support, and stability and pose a clinical challenge to the success of complete denture prostheses. Extreme ridge resorption also increases the interridge distance. Restoration of the vertical dimension and esthetics thus demands increased height of the prosthesis and in turn leads to an increase in prosthesis weight. Reducing the weight of the denture enhances stability and retention and reduces further resorption of the jaw, thereby favoring the prognosis of the denture. This report describes the rehabilitation of an edentulous patient with resorbed maxillary and mandibular ridges and an increased interridge distance using simplified techniques of fabricating hollow dentures.
严重萎缩的牙槽嵴导致固位、支持和稳定性降低，给全口义齿修复的成功带来临床挑战。极端的牙槽嵴吸收也会增加牙槽嵴间距离。因此，恢复垂直距离和美观需要增加义齿的高度，从而导致义齿重量增加。减轻义齿的重量可以提高稳定性和固位力，并减少颌骨进一步吸收，从而有利于义齿的预后。本报告介绍了使用制作中空义齿的简化技术对一位上颌和下颌牙槽嵴吸收、牙槽嵴间距离增加的无牙患者进行修复的情况。
