DEFINITION

Classification: 433/167

PROSTHODONTICS:

(under the class definition) Subject matter relating to artificial teeth.

(1) Note. Utilization of an existing tooth or portion thereof for purpose other than fastening adjacent artificial

teeth is considered repair rather than replacement.

(2) Note. Methods for making dental prostheses are proper for Class 433 if they include specific dental steps (e.g., impression taking, fitting the patient with the denture, etc.). Generally, those process claims which recite only manufacturing steps will be classified in the appropriate manufacturing class (see search notes below). A claim to a dental prosthesis, per se, is properly classified in this class if significant structure is recited.

SEE OR SEARCH THIS CLASS, SUBCLASS:

25, for apparatus employed in the process of replacing missing teeth with artificial teeth.

215+, for a method or material for replacing a portion of a natural tooth.

SEE OR SEARCH CLASS 29, Metal Working,

400.1+, for processes of mechanical manufacture including diverse manufacturing steps.

72, Metal Deforming, appropriate subclasses for a method or apparatus for die shaping a denture base or other prosthodontic element.

106, Compositions: Coating or Plastic,

35, for plastic or coating compositions used in dental prostheses.

164, Metal Founding, appropriate subclasses for a method of casting a prostodontic element.

205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compositions,

67+, for electroforming methods for production of dentures.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

16+, for a process for forming a denture or element thereof.

520, Synthetic Resins or Natural Rubbers, appropriate subclasses, particularly Class 523,

105+, for nonmedicated compositions containing a synthetic resin having utility specifically intended to be for contact with animal living tissue, especially subclasses 109 and 113-120 for dental compositions or to processes of preparing said compositions.
