Article Synopsis
- - A 69-year-old male patient received new dental prosthetics, specifically a fixed prosthesis for his lower jaw and a complete denture for his upper jaw, after 15 years, utilizing a strong nanocomposite framework.
- - Three years post-delivery, the patient reported no significant issues with the prosthetics, indicating a high level of satisfaction with the treatment.
- - The study highlights the benefits of using Ce-TZP/A material over traditional methods, though it notes limitations due to its opaque color affecting aesthetics; further research is needed for broader conclusions.
Ceria-stabilized zirconia/alumina nanocomposite (Ce-TZP/A) exhibits an elasticity equivalent to that of cobalt-chromium alloy and a flexural property that is superior to that of yttria-tetragonal zirconia polycrystal. Therefore, the use of Ce-TZP/A for the fabrication of removable dental prosthesis frameworks is being studied. However, the current English literature does not include any clinical report on the use of Ce-TZP/A for the fabrication of the entire framework.

- * Serious bone loss complicates treatment when multiple implants support a fixed structure, making repairs more challenging.
- * A clinical case showed that a partial denture effectively repaired a multi-implant restoration after one implant was removed due to bone resorption, leading to satisfactory results over three years.
This article describes a technique for fabricating cement-retained crowns over a customized gingiva-colored composite resin screw-retained implant infrastructure. This prosthetic design is not significantly influenced by unsuitable implant position, alignment, or angulation. Consequently, the cement-retained crowns can be reproduced in an esthetically and functionally appropriate morphology, regardless of where the screw-access openings are located in the infrastructure.

Nippon Ganka Gakkai Zasshi
February 2002
Purpose: To assess the whether glistening(GP) occurs on silicon lenses.
Methods: ALLERGAN, SI-40NB and CANON STAAR, AQ110NV lenses(Alcon MA60BM control). The lenses were immersed in 50 degrees C physiological saline solution for 2 hours, and then immersed in 35 degrees C physiological saline solution.
