Dental Clinical Trial
Official title:
Evaluation of Patient Satisfaction and Maximum Biting Force of Three Different Constructed Bars in Implant Overdenture in One Year Follow-up
Statement of problem. Patient satisfaction and maximum biting force from patients who wear 2-implant-retained overdentures with different constructed bar attachments can be improved. Purpose. This randomised controlled clinical trial assessed patient satisfaction and maximum biting force with three differently constructed bar-retained overdentures (conventional casting, Milling and 3D printing CAD/CAM techniques) within a one-year follow-up. Material and methods. A total of 60 implants were placed in 30 mandibular jaws(30 participants). The jaws were randomly assigned to 1 of the 3 treatment groups: a 10 conventional technique cast Co-Cr bar attachment, a 10 Co-Cr CAD/CAM milled bar attachment, and a 10 Co-Cr CAD/CAM 3D-printed bar attachment all groups were connected to 2 implants in the canine area. Patient satisfaction was tested after 6 months, and 12 months for each group; the results were collected, tabulated, and statistically analysed using a Pair-wise comparisons test and the Kruskal-Wallis test. Maximum biting force was tested at baseline,3 months, 6 months, and 12 months for each group; the results were collected, tabulated, and statistically analysed using a Pair-wise comparisons test and ANOVA test.
