A Study Comparing Two Different Denture Base Materials in Implant Retained Overdentures

The depth of the gingival sulcus will be measured around each implant using a graduated periodontal probe. This probe will be inserted between the oral sulcular epithelium and the implant with minimal pressure. The distance from the tip of the probe and the free gingival margin will be measured and recorded to the nearest millimeter. Four readings were recorded at the middle of the four surfaces, buccal, lingual, mesial, and distal. The mean of the four readings will be considered as the pocket depth for this group at the chosen time.

Amount of plaque accumulation was graded from (0 to 3) where: Grade 0: No plaque detected by passing the side of probe along the implant. Grade 1: Film of plaque detected by probing. Grade 2: Moderate accumulation of soft debris, which can be seen by the naked eye. Grade 3: Too much soft matter within the sulcus, gingival margin, and adjacent implant surface. For each group, four readings were recorded at the middle of the four surfaces, buccal, lingual, mesial, and distal. The mean of the four readings was considered as the plaque index for this group at the chosen times

A sterile swab will be rubbed on the intaglio surface of the denture. The swab will be placed in a tube containing 1 ml phosphate buffered saline solution and sonicated for 5 minutes at 35 kHz. - Serial decimal dilutions (100 to 10-2)will be prepared from the sonicated swab solution. - 100 µl of the sonicated solution will be inoculated on Sabouraud's dextrose agar at 37°C for 48 hours. - After incubation, the agar plate will be retrieved, and the number of colonies will be counted and tabulated for statistical analysis

Participant satisfaction will be measured using a visual analog scale (VAS) questionnaire. The questions include the appearance, ease of cleaning, speaking ability, eating comfort, and overall satisfaction of their dentures.

Participants will marked the amount of satisfaction on a 100-mm-length line (0 = no satisfaction at all and 100 = complete satisfaction). At a location that corresponded to the subject's subjective emotion, a pencil mark was drawn across the horizontal line. The distance in millimeters between the left end limit and the pencil mark point, which represents the subject's VAS score, will then be used to calculate satisfaction. The subject's perception of the prosthesis improves with a higher score. Using the VAS scores, satisfaction levels were categorized as follows: completely unsatisfied (0-31), somewhat unhappy (>31-50), slightly satisfied (>50-79), and satisfied (>79). The questionnaire was given to the patients in Arabic

The oral health impact profile (OHIP-14) questions will be utilized to assess OHRQoL. The questions are composed of seven domains: functional limitations (pronouncing sounds, sense of taste), physical pains (painful aching, comfort on eating), psychologic discomforts (self-consciousness, feeling tense), physical disabilities (unsatisfactory diet, interrupting meals), psychologic disabilities (difficult to relax, embarrassment), social disabilities (irritability with people, difficulty in jobs), and handicapping (life in general, inability to function). The responses for questions are never (=1), hardly ever (=2), occasionally (=3), fairly often (=4), and very often (=5). Lower scores indicate increased satisfaction, and higher scores indicate decreased satisfaction.
