Although advances in methods and improved materials have contributed to better treatment results, caries and periodontal problems still remain significant threats to overdenture service life. The prevention of caries and recurrent periodontal disease thus becomes a most important aspect of postinsertion care. Undoubtedly, there are a number of successful overdenture methods. This article outlines two treatment sequences previously described by Brewer and Morrow that continue to be effective (Fig. 23). Common to most overdenture techniques is that an overdenture may be the only treatment that permits retention using the patient's last few retainable teeth. A conservative approach to root preservation still is a valid and practical measure in preventative dentistry.
尽管方法上的进步和材料的改进有助于取得更好的治疗效果，但龋齿和牙周问题仍然是覆盖义齿使用寿命的重大威胁。因此，预防龋齿和复发性牙周病成为义齿佩戴后护理的一个最重要方面。毫无疑问，有许多成功的覆盖义齿方法。本文概述了布鲁尔和莫罗之前描述的两种治疗方案，它们仍然有效（图23）。大多数覆盖义齿技术的共同点是，覆盖义齿可能是唯一一种允许利用患者最后几颗可保留牙齿进行固位的治疗方法。在预防性牙科中，保守的牙根保留方法仍然是一种有效且实用的措施。
