This document discusses how dental implants can improve denture retention and provides three case studies as examples. Dental implants are inserted into the patient's mouth and used to support and retain dentures. A variety of retention mechanisms are available. The first case describes a patient who received an upper and lower denture supported by two implants each. The second case involved a patient whose upper denture lacked stability, so they received six implants in the upper jaw. The third case combined a removable upper denture supported by four implants and fixed crowns in the lower jaw replacing posterior teeth.
