Four Implant Retained Mandibular Overdenture VERSUS Fixed-detachable Prosthesis.

Patient Satisfaction and Oral Health Related Quality of Life for Four Implant Retained Mandibular Overdenture VERSUS Fixed-detachable Prosthesis. Crossover Clinical Study

ABSTRACT Statement of the problem: completely edentulous patient can be treated by four implants for implant retained overdenture or fixed detachable prosthesis.

Purpose: the purpose of this clinical study is to evaluate patient satisfaction and oral health impact profile (OHIP-14) for four implant retained complete Overdenture versus Fixed-detachable prosthesis.

Material and methods: This clinical cross-over study included 10 completely edentulous patients with maxillary single denture and four parallel implants were placed intraforminal. Every patient received two mandibular implants at the 1st premolar region and two mandibular implants in lateral incisor region. Ten completely edentulous patients received implant retained overdenture for six months (Group I), then fixed detachable prostheses on four implants for the following six months (Group II). For both designs, patient satisfaction using visual analogue scale (VAS) and oral health impact profile (OHIP-14) will be recorded for both prostheses. SPSS program will be used for statistical analysis.

Inclusion Criteria:

• Inclusion Criteria:
• This research will be done on patients who were previously received 2 mesially placed implants in the 1st premolar region with only two remaining mandibular canines with opposing maxillary single denture

Exclusion Criteria:
