Preservation of ridge dimensions is critical for denture success. For long the concept of an internally weighted denture, which suggested that gravity and the additional weight to the mandibular complete denture aids in prosthetic retention is widely accepted. However, excessive weight and pressure can accelerate bone resorption. Here, we describe a unique modification of internally weighted metal denture base for the resorbed mandibular ridge with an incorporated additional hollow section over the anterior knife-edge ridge. The weight provided retention and stability while the hollow portion prevented further resorption of the bone.
保留牙槽嵴尺寸对义齿成功至关重要。长期以来，内部加重义齿的概念，即重力和下颌全口义齿的额外重量有助于义齿固位，已被广泛接受。然而，过重和压力会加速骨吸收。在此，我们描述了一种针对吸收后的下颌牙槽嵴的内部加重金属义齿基托的独特改良，在前缘刃状嵴上方合并了一个额外的中空部分。重量提供了固位和稳定性，而中空部分则防止了骨的进一步吸收。
