Titanium-Ceramic restoration: How to Improve the Binding Betwwn Titanium and Ceramic

---

Titanium alloys has been used as an alternative to nickel –chromium alloys for netral ceramic restronations because of its good biocompatibility and mechanical di properties. This indicated that it was possible to design coping according to standards eatablished for metal ceramics. However,,titanium is chemically reacting stroughly wwith gasenous elements which causes problems when ceramics are fused to titanium. Purpose: To provide information about improving the bondings between titanium and ceramic. Titanium has two crystal modification, the close—packed hexagonal (α) struture, up to 880⁰C, and above this temperature the body centered cubic (β) structure. The principal problem is the eensive disolution of oxygen resulting in thich , oxigen rich titanium layers-colled α-case that horms the bonding of ceramic to vitamin and the great mismatch in the coefficien of thermal expansion of conventional ultra fusing ceramic. Methods been developed for fusing ceramic to vitamin like processing methods the used of ultra-low fusing vitamin ceramic, bonding agent, and protocol for ceramic bonding to titanium. Conclusion: Titanium and titanium alloys, based on their physical and chemical propertics suitable for titanium-ceramic retrorations, but curful selection of processing methods, ceramic material, laboratory skill and strict protocol for ceramic bonding to titanium are necessary to omprove the bonding between titanium and ceramic.
