The present invention generally relates to the use of pre-formed bodies of Chemically Bonded Ceramics (CBCs) biomaterial for implantation purposes wherein the bodies are prepared ex vivo allowing process parameters to be optimized for desired long term properties of the resulting CBC biomaterial. More particularly, the pre-formed CBC material bodies of the present invention are sintered. The pre-formed body of CBC material is machined to the desired geometry and then implanted using a CBC cementation paste for fixation of the body to tissue. The invention also relates to a method of preparing pre-formed bodies of CBC biomaterial for implantation purposes, methods of preparing an implant thereof having desired geometry, and a method of implantation of the implant, as well as a kit for use in the method of implantation.

A Addition-fragmentation oligomers containing allylic disulfide groups are described. The oligomers may be added to polymerizable compositions to provide labile crosslinks that can cleave and reform during the polymerization process.

The present specification provides a dental glass ionomer cement (GIC) composition comprising a zwitterionic material and a glass ionomer cement, and a method of preparing the same.
