Root overdentures and implant overdentures are two similar treatment options for the nearly-edentulous or edentulous mandible. The purpose of this literature review was to specifically compare their prosthodontic treatment philosophies and follow-up maintenance requirements. Critical comparison of these two prosthodontic treatment philosophies revealed that the foundation for overdentures which is provided by oral implants is more predictable than that provided by the roots of natural teeth. The two treatment modalities have both similarities and differences in their associated prosthodontic maintenance. The findings of this literature review suggest the future possibility that mandibular root overdentures may become obsolete as a treatment approach.
根上覆盖义齿和种植体覆盖义齿是针对下颌近无牙或无牙情况的两种相似治疗选择。本文献综述的目的是具体比较它们的修复治疗理念和随访维护要求。对这两种修复治疗理念的批判性比较表明，口腔种植体为覆盖义齿提供的基础比天然牙的牙根提供的基础更具可预测性。这两种治疗方式在相关的修复维护方面既有相似之处也有不同之处。本文献综述的结果表明，下颌根上覆盖义齿作为一种治疗方法未来可能会过时。
