| Popis: | Supported by grant no PYO.DIS.1904.13.001 from Ondokuz Mayis University Coordination of Scientific Research Projects Statement of Problem. The bond strength of dental porcelain to titanium is inadequate as a clinical alternative to conventional alloys for metal ceramic restorations. Purpose. The purpose of this in vitro study was to evaluate the effects of coating titanium surface with a micro-arc oxidation (MAO) technique and hydroxyapatite (HA) on the bond strength of porcelain to titanium surfaces. Material and methods. One hundred twenty machined titanium specimens with a dimension of 25x3x0.5 mm were prepared from grade 5 titanium as the metal substrate. Specimens were divided into 6 groups (n=20) according to the surface treatment used: airborne-particle abraded (control), coated with MAO for 5 minutes, coated with MAO for 15 minutes, coated with MAO for 30 minutes, coated with HA, and combination of MAO and HA. Each group was further divided into 2 subgroups (n=10) according to the type of porcelain used: Noritake Ti-22 porcelain or Vita-Titankeramik porcelain. The bond strength was tested with a universal testing machine at a crosshead speed of 0.5 mm/min. Data were analyzed statistically with 2-way ANOVA and Tukey honest significant differences multiple comparison tests (alpha=.05). Results. For both porcelain groups, the 30-minute MAO groups showed higher bond strength values than those of the control groups (P.05). Surface roughness was affected significantly (P Ondokuz Mayis University Coordination of Scientific Research Projects [PYO.DIS.1904.13.001] |
