Alumina, Zirconia and Zircon as Bone Substitute. Experimental Work on Dogs’ Jaw

Article Preview

Abstract:

This Study is based on the search and selection of suitable bioceramic materials as bone substitute in cases where the osseous tissue is lost. A total of 42 pieces were used divided in 3 groups: 14 of Alumina (Al2O3), 14 of Zirconia (ZrO2) and 14 of Zircon (ZrSiO4). The bioceramic materials were inserted on 21 adult dogs divided in 3 groups of 7 animals, implanted on both sides of the jaw. The main objective of this work is to evaluate the ceramic-bone interface. The results obtained were verified through clinical, radiographic and histological exams at the 40th day of the postoperatory time. A fibrous capsule was found in 36% of the cases where ZrO2 was inserted in contraposition with the Al2O3 and the ZrSiO4 where the bone formation was verified in 100 % and 92 % respectively.
