Intervention(s)

The patients enrolled in the study (n=50) were divided into two main batches (three groups in batch one and two groups in batch two), with a total of ten patients in each group. The patients were randomly assigned into groups. The three groups in the first batch received three different denture base materials for the constructed palatal plate and rouge area of the complete dentures, (flexible acrylic resin, heat cure acrylic resin, and chrome cobalt metallic base). Another batch (twenty patients) divided into two groups received different teeth types: acrylic teeth and porcelain teeth.

Primary Outcome(s)

The evaluation of the speech quality was made by measuring the phonetics. The patients were connected to a spectrogram and were asked to verbalize Arabic pronunciation letters (?? ?? ???). The mean of the sound levels was calculated for each patient, and subsequently tabulated and analyzed. The evaluation was made immediately following denture insertion: three weeks, and ten weeks following the insertion of dentures by a computerized speech lab (spectrogram). This measurement protocol was implemented for two batches. The level of sound in patients with complete dentures made from different base materials or different teeth was assessed via a spectrogram. (it was measured at insertion, 3 weeks later and after 10 weeks)
