Patient's Satisfaction of Mandibular Implant Supported Overdentures With Reduced Denture Base Extensions.

This study aimed to compare reduced (partially extended) denture bases with fully extended bases regarding patient satisfaction, oral health-related quality of life (OHRQoL), and masticatory efficiency. A within-subject study design was carried out; involving 20 completely edentulous participants aged 50-75 years, who received newly constructed conventional complete denture. Four parallel implants were installed in the interforaminal region, implant overdenture (IOD) retained by bar attachment was constructed for each patient and were provided with two different overdenture designs: (1)firstly a fully extended denture base (FIOD) (2) then a reduced (partially extended) denture base (RIOD). Each patient allowed to wear each types of overdentures for a period of 3 months prior to evaluation. The following outcome measures were assessed: Patient satisfaction, the Oral Health Impact Profile (OHIP-14), and Chewing efficiency were assessed.
