Claims
- 1. A process for filling teeth comprising
- applying to a prepared tooth cavity a light polymerizable adhesive comprising
- a polymerizable resin composition comprising
- (a) more than about 50% by weight of at least one silane having the formula ##STR6## where R.sub.1 -R.sub.4 are the same or different and are H, alkyl, alkenyl, aryl, aralkyl, alkaryl, alkoxy, vinyl, aryloxy, or acyloxy having from 1 to about 30 carbon atoms and where at least one of R.sub.1 -R.sub.4 is alkyl, aryl, aralkyl or alkaryl having from 1 to about 30 carbon atoms and is substituted with at least one group having the formula ##STR7## where R.sub.5 is H, alkyl or alkenyl having from 1 to about 6 carbon atoms, and
- (b) up to about 50% of a polymerizable ethylenically unsaturated material, and
- an amount of a photosensitizing system effective to cause polymerization of said adhesive when said adhesive is exposed to actinic light, and exposing said adhesive to actinic light for a time sufficient to harden said adhesive.
- 2. The process of claim 1 wherein said polymerization resin composition further comprises from about 0.5% to about 10% by weight of the resin of a material having the formula ##STR8## where R.sub.6 is alkyl, aryl, alkaryl or aralkyl having from 1 to about 30 carbon atoms and R.sub.1 -R.sub.3 have the same meaning defined in claim 1.
- 3. The process of claim 2 wherein R.sub.1 -R.sub.3 were alkoxy(alkoxy) groups.
- 4. The process of claim 1 further comprising an amount of particulate, inorganic filler sufficient to render said adhesive thixotropic.
- 5. The process of claim 1 wherein said photosensitizing system comprises at least on alpha diketone and an amine.
- 6. The process of claim 1 wherein said photosensitizing system comprises either a benzoin compound or a compound having the formula ##STR9## where R.sub.7 and R.sub.8 are the same or different and are alkyl or aryl.
