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 Morrow² 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.
