Abstract
The present invention provides a medical film material which comprises a flat-plate-like or film-like demineralized dentin matrix (DDM) that is derived from a removed bovine tooth and completely demineralized, and which has an area falling within the range front 2 to 50 cm2. The present invention also provides a method for surgerizing a non-human animal using the medical film material. The present invention also provides a method for producing the medical film material, which comprises thinning and demineralizing a removed bovine tooth to produce a demineralized dentin matrix (DDM) film that is completely demineralized, wherein either one of the thinning procedure and the demineralization procedure may be carried out first.
