Claims39
An article comprising:
- an orthodontic bracket having a base for bonding the bracket to a tooth;
- a first part of an at least two-part adhesive on the base of the bracket, the first part comprising a polymerizable component, a polymerization initiator, and at least about 10% by weight, based on the total weight of the first part, of a filler comprising a silica filler;
- and
- a release substrate comprising a surface in contact with the first part.

A kit comprising:
- an orthodontic bracket having a base for bonding the bracket to a tooth, a first part of an at least two-part adhesive on the base, and a release substrate comprising a surface in contact with the first part, wherein the first part comprises a polymerizable component, a polymerization initiator, and at least about 10% by weight, based on the total weight of the first part, of a filler comprising a silica filler;
- and
- a second part of the at least two-part adhesive comprising a polymerizable component and an activator.
A method for bonding an orthodontic bracket to a tooth comprising:
- providing an orthodontic bracket having a base for bonding the bracket to a tooth, a first part of an at least two-part adhesive on the base, and a release substrate comprising a surface in contact with the first part, wherein the first part comprises a polymerizable component, a polymerization initiator, and at least about 10% by weight, based on the total weight of the first part, of a filler comprising a silica filler;
- applying a second part of the at least two-part adhesive to the tooth surface, the second part comprising a polymerizable component and an activator for the polymerization initiator in the first part;
- separating the orthodontic bracket having the first part on the base from the release substrate;
- and
- applying the base of the bracket to the tooth surface having thereon the second part of the at least two-part adhesive.
