简要总结
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.

入选标准
- •Patients with sufficient residual alveolar bone quantity and quality anterior to the mental foramen to receive self-taping root form titanium implants.
- •Maxillary and Mandibular residual alveolar ridges covered with healthy mucosa without any remaining roots or local inflammation.
