Abstract
An apparatus and method of use that include a dental model, a support that includes a mounting surface and a stretch release pressure sensitive adhesive located between the dental model and the support. The stretch release pressure sensitive adhesive attaches the dental model to the mounting surface. In an additional embodiment, a highly extensible and substantially inelastic backing having a layer of the stretch release pressure sensitive adhesive is used to attach the dental model to the mounting surface. The dental model and the support are separated without damage by stretching the stretch release pressure sensitive adhesive at an angle no greater than about 35 degrees from the mounting surface.
Claims36
An apparatus comprising:
- a dental model;
- a support comprising a mounting surface;
- and
- stretch release pressure sensitive adhesive located between the dental model and the support, wherein the stretch release pressure sensitive adhesive attaches the dental model to the mounting surface, and where the dental model and the support are separable by stretching the stretch release pressure sensitive adhesive at an angle no greater than about 35 degrees from the mounting surface.
A method comprising:
- positioning stretch release pressure sensitive adhesive between a dental model and a mounting surface of a support;
- attaching the dental model to the mounting surface of the support with the stretch release pressure sensitive adhesive;
- and
- removing the dental model from the mounting surface by stretching the stretch release pressure sensitive adhesive at an angle of no greater than about 35 degrees from the mounting surface of the support.
A kit comprising:
- mold material;
- and
- an attachment article comprising stretch release pressure sensitive adhesive for attaching a dental model made from the mold material to a mounting surface of a support, where the dental model and the support are separable by stretching the stretch release pressure sensitive adhesive at an angle no greater than about 35 degrees from the mounting surface;
- at least one release liner releasably adhered to at least a portion of the stretch release pressure sensitive adhesive;
- and
- a package containing the mold material and the attachment article.
