The chemistry of a wide variety of unsaturateo spiro ortho carbonates and unsaturated spiro ortho esters have been discussed in detail previously (14,19,24,27-X). They not only are useful for monomers that expaiu on polymerization Qa,32-21) but are useful as dental filling materials (38), for the syntHesTs of oligomers capped with hydroxyl groups, pro( ction of biodegradable polymers, and enhancement of thermal stability of copolymers (39-45) ... 

In most medical and paramedical applications of plastics, the materials used are those aheady produced by the manufacturers in a polymerized or formulated form. Certain surgical and dental apphcations, however, require that the material be polymerized or formulated just prior to use. Surgical cements and adhesives, a host of dental filling materials, materials for dentures, cavity liners, and protective coatings for tooth surfaces are in this category.

Successful copolymerization ofbenzophenone methacrylate and methyl methacrylate allowed to obtain hybrids cross-linkable under UV light. They can have a great potential as dental filling materials with smaller toxicity and higher biocompatibility when compared to those which are currently used. 

These cements are based on the reaction product of phosphoric acid with other materials, such as sodium silicate, metal oxides and hydroxides, and the salts of the basic elements. Zinc phosphate is the most important phosphate cement and is widely used as permanent dental cement. It is also modified with silicones to produce dental-filling materials. Compressive strengths of up to 200 MPa are typical of these materials, which are formulated to have good resistance to water. Copper phosphates are used for similar applications, but they have a shorter useful life and are used primarily for their antiseptic qualities. Magnesium, aluminum, chromium, and zirconium phosphates are also used. ...
