This research is being done to find out the ideal number of implants/attachments required to provide adequate stability of dentures during function.
The aim of this study is threefold: i) to evaluate within-subject response to complete lower dentures retained by 1 or 2 or 3 implants fitted with independent overdenture attachments; ii) laboratory evaluation of the retention force generated with 1-2 or 3-implants and study its correlation to patients' response; iii) study the wear pattern of the plastic inserts on the overdenture abutments during each retention mode (i.e. the number of implants used to retain the dentures) and correlate its effects to denture stability.

RECRUITINGPatient Satisfaction survey (questionnaires)
Assess efficacy of treatment by analysis of patient's answer to a satisfaction survey.
Time frame: every 6 months up to three years
Radiographs
Assess crestal bone level around the implants.
Time frame: every 6 months up to three years
Wear of 1 vs 2 vs 3 GPS retention components on complete dentures.
The force required to remove the female retentive componenets from the male component will be compaired between one vs two vs three retentive components.
Time frame: baseline and 6 months
