Prosthetic rehabilitation of severely atrophic ridges has always been an ordeal for the clinician due to decreased support, stability and retention. Because of severe resorption the restorative space between maxillary and mandibular residual ridges is increased. Rehabilitation in such cases may result in increased height and weight of the prosthesis further compromising its retention and stability. This in turn overloads the underlying hard and soft tissues exacerbating ridge resorption so, in order to break this vicious cycle, the weight of the prosthesis needs to be reduced which can be achieved by making hollow prosthesis. This article describes a novel technique of fabricating a hollow maxillary complete denture.
严重萎缩牙槽嵴的修复重建对临床医生来说一直是一项艰巨的任务，因为其支持、稳定和固位功能均有所下降。由于严重吸收，上颌和下颌残余牙槽嵴之间的修复间隙增大。在这种情况下进行修复可能会导致义齿的高度和重量增加，进而进一步损害其固位和稳定性。这反过来又会使下方的软硬组织负荷过重，加剧牙槽嵴吸收。因此，为了打破这种恶性循环，需要减轻义齿的重量，这可以通过制作中空义齿来实现。本文介绍了一种制作中空上颌全口义齿的新技术。
