Study Description
Brief Summary
The aim of this study will be the evaluation of patient satisfaction and oral health-related-quality of life (OHRQoL) of two versus four implants supporting fixed full-arch screw-retained metal acrylic hybrid mandibular prosthesis.

Detailed Description
-
Six completely edentulous patients will be selected for this study from the outpatient clinic of the prosthodontic department
-
All patients will be informed about all surgical and prosthodontics procedures that will be done for them. All patients will sign the consent form of the ethical committee in faculty dentistry Mansoura University.
The patients will be divided into 2 groups
-
Control group: will receive implant-supported mandibular fixed metal acrylic prosthesis on 4 implants that were placed according to the "All on four concept".
-
Study group: will receive implant-supported mandibular fixed metal acrylic prosthesis on two implants placed according to "All On two concept".

Outcome Measures
Primary Outcome Measures
- Visual analog scale (VAS) questionnaire [one year]
Regarding VAS, participants were asked to score their answer according to the amount of satisfaction on a 100mm line (Score zero = no satisfaction at all and score 100 = complete satisfaction). The questions cover several items related to prosthesis such as: retention, stability, comfort, ease of cleaning, ease of speaking, ease of chewing, limited activities due to embarrassment, quality of bolus and appearance
- crestal bone loss [one year]
measuring marginal bone loss in mm around dental implants by digital radiography
- plaque index [one year]
evaluation of plaque accumulation around dental implants using scores.score 0; absence plaque , score 1; plaque only detected by a probe passing through the smooth marginal surface of the implant, score 2; plaque can be recognized by naked eye, and score 3; plenty of soft matter
- gingival index [one year]
evaluation of gingival bleeding using scoring system as following: scores.0; no bleeding when a periodontal probe is passed along the mucosal margin, 1;isolated bleeding spots visible, 2; blood forms a confluent red line on the mucosal margin, 3;heavy or profuse bleeding.
- pocket depth [one year]
evaluation of pocket depth in mm around dental implants
Secondary Outcome Measures
- Quality of Life (Secondary Outcome). [one year]
The oral Health impact profile (OHIP-14) questions were utilized to assess OHRQoL. The questions were composed of seven domains
- prosthesis maintenance and survival rate [one year]
measuring the survival rate of the mandibular prosthesis in both groups
