CLINICAL AND RADIOGRAPHICAL EVALUATION OF ENDOCROWNS FABRICATED FROM DIFFERENT CAD/CAM CERAMIC MATERIALS

This study aimed to evaluate patient satisfaction via the visual analogue scale and conduct radiological assessments of the marginal adaptation of the cemented CAD/CAM endocrowns at different time intervals. Twenty-six (26) participants received endocrowns constructed from lithium disilicate ceramics and multi-layered zirconia. The construction and cementation of the endocrowns were carried out according to the manufacturer's instructions for laboratory and clinical procedures. The statistical significance was set at p ≤ 0.05. Most of the participants recorded high numbers and percentages for the very satisfied and satisfied scales when evaluating the colour, crown morphology, and margins. The McNemar test revealed a significant difference in the colour at the 24-month follow-up (p = 0.037). No significant differences were detected at different time intervals in terms of the khat chewing habit, side, and arch type with cemented endocrowns. The Chi-square test revealed significant differences in the material type at baseline (p = 0.001); in the gender at 24 months (p = 0.024); and in the colour, margin, and morphology at baseline and 24 months (p ˂ 0.001 and p=0.004, respectively). Most patients expressed high satisfaction with the colour, morphology, and marginal adaptation of the cemented endocrowns. The use of lithium disilicate ceramics resulted in higher levels of satisfaction in terms of the colour and marginal adaptation compared with zirconia.
