ABSTRACT
This chapter will describe prosthodontic complications and the postinsertion maintenance of the completed implant dentures. Complications may occur before, during, and after the prosthodontic phase of implant treatment; maintenance and repairs of the dentures and components will be required after the overdentures are fitted. Various studies have shown different results for the maintenance requirements for implant overdentures. There is also conflicting evidence on whether implant overdentures require more or less maintenance than fixed restorations.
