Abstract
BACKGROUND: In recent years, development of zirconia abutments has e a hotspot. The zirconia all-ceramic crowns and 1Qingdao University
zirconia abutments restoration are recognized by many clinicians and patients because of their excellent aesthetic restoration Medical School,
effects, and the fit accuracy between them is a key factor for the implant restoration. Qingdao 266003,
Shandong Province,
OBJECTIVE: To develop the zirconia abutments and to study the fitness of the interface between the zirconia abutments and China; 2Department
zirconia crowns. of Stomatology,
METHODS: Nanometer zirconia powder was used to manufacture zirconia abutments by injection molding. Five zirconia Affiliated Hospital of
abutments and five titanium abutments were divided into two groups: Zirconia abutments-zirconia crowns group and titanium Qingdao University
Medical School,
abutments-Co-Cr alloy based PFM crowns group. In the zirconia abutments-zirconia crowns group, five zirconia crowns were Qingdao 266003,
made upon the zirconia abutments puter aide
