Abstract

Mandibular implant-supported overdenture (ISOD) with high retention and patient satisfaction is more preferred than conventional complete denture (CCD). The main objectives were to evaluate chewing efficiency and patients’ satisfaction with four fixed implant supported mandibular overdentures and compared with conventional complete dentures. Twenty-five (11 males and 14 females) were recruited. They were recruited into five groups as followings: 5 patients each recruited for conventional complete denture, 5 patients with two pieces implant ball and socket overdenture, 5 patients with implant locator overdenture, 5 patients with single piece implant ball and socket overdenture and 5 patients with innovate implant overdenture by locator system. The results of chewing activity of the walnut and passed through the sieves during four visits revealed of conventional complete denture and different types of implant supported overdenture. The outcome showed that the mean values of the highest level of chewing capacity in two pieces’ implant ball and socket then single piece ball and the lowest level of chewing capacity in conventional complete denture were seen. Whereas, the implant locator had almost higher capacity than the innovative implant overdenture, and both of them were very similar especially in the first, second and third visits with passed through the spited walnuts into the sieve, respectively. Between the first and fourth visit regarding the conventional denture and different types of overdentures with improvement of chewing activity for the ISOD although there was improvement of patient satisfaction but it was not significant. The current results exert benefits of treatment of edentulous patients, to better chewing activity, masticatory efficiency and patient satisfaction in edentulous patients‎‎.
