Abstract

Objective
To evaluate the effect of ball and socket and bar/clip attachments in implant-retained complete mandibular thermoplastic overdenture on masticatory performance.
Subjects and Methods
Ten completely edentulous patients divided into two groups: Group I (n=5) was treated with two implant retained thermoplastic overdenture with ball and socket attachment system then after 3 months replaced by custom made bar. Group II (n=5) was treated with two implant retained thermoplastic overdenture with custom made bar attachment system then after 3 months replaced by ball and socket. The masticatory performance test measurements were recorded for each patient: at insertion, after 1 month and after 3 months for each attachment.
