Dental implants can be used to retain partial dentures in areas where supporting teeth are weakened or missing (Figures 1a-d). Advantages of using implants for retention of partial dentures include improved function and esthetics, better stability, as well as improved long term prognosis of the existing teeth due to decreased stress.

Dental Implants For Retention Of Complete Dentures
Dental implants can be used to provide proper retention for removable complete dentures. Due to unfavorable anatomy of the lower jaw, and movement of the tongue, retention of conventional complete dentures is difficult. Two to four implants can be predictably used to provide adequate retention of the dentures (Figures 2a-d). Implant retained dentures are more comfortable, more stable, and provide better function. In addition, dental implants minimize natural bone resorption which is common in completely edentulous jaws.
