The traditional treatment for an edentulous maxilla opposed by a partially edentulous mandible with a complete denture and a distal extension removable partial denture is fundamentally inadequate. Continuing resorption of alveolar bone under the denture base of the removable partial denture causes changes in the occlusal plane. Consequently, overloading of the anterior maxillary region occurs, usually leading to increased bone resorption in the anterior maxillary ridge. Placement of implants beneath the distal extension denture base of the removable partial denture can result in a stable and durable occlusion. Two patients in whom the use of implants combined with a cast metal removable partial denture provided occlusal stability and improved functional comfort are presented.
对于上颌无牙、下颌部分无牙且佩戴全口义齿和远中游离可摘局部义齿的患者，传统治疗方法从根本上来说是不够的。可摘局部义齿基托下的牙槽骨持续吸收会导致咬合平面发生变化。因此，上颌前部区域会出现负荷过重的情况，通常会导致上颌前部牙槽嵴骨吸收增加。在可摘局部义齿的远中游离义齿基托下方植入种植体可实现稳定且持久的咬合。本文介绍了两名患者，在他们的治疗中，种植体与铸造金属可摘局部义齿联合使用，实现了咬合稳定并提高了功能舒适度。
