Overdenture techniques can be modified for use with implants. Generally the implants, which replace the tooth roots, can be placed in a position to permit optimum retention and stability as well as enhancing esthetics. Bony undercuts, which at times are present with the retention of tooth roots, are not a problem when using implants. Various retentive schemes are available to retain the prosthesis and can be matched to the individual needs of patients in regard to retention, stability, and the ability to insert and remove prostheses. Two implants can adequately support an overdenture. The superstructure must be designed to enable the patient to maintain a healthy oral environment. The patient must understand and be able to perform required oral hygiene procedures. The use of overdentures over implants affords the dentist another option in meeting the needs of the patients.
覆盖义齿技术可进行改良以用于种植体。一般来说，替代牙根的种植体可以放置在一个位置，以实现最佳的固位和稳定性，并提升美观度。牙根保留时有时会出现的骨倒凹，在使用种植体时并非问题。有多种固位方案可用于固定义齿，并且可以根据患者在固位、稳定性以及义齿插入和取出能力方面的个体需求进行匹配。两颗种植体就可以充分支撑覆盖义齿。上部结构的设计必须使患者能够保持健康的口腔环境。患者必须理解并能够执行所需的口腔卫生程序。使用种植体支持的覆盖义齿为牙医满足患者需求提供了另一种选择。
