DEFINITION

Classification: 427/2.26

For mineralized body part (e.g., bone, tooth, crown, hip):

(under subclass 2.24) Processes in which the product is an implantable prosthesis for a mineralized body part, such as bone or tooth replacement; parts, subcombinations, or intermediates thereof or therefor.

(1) Note. The subject matter here must be, at least in part, intended to replace or assist a missing or defective mineralized portion of the body.

(1) Note. The prosthesis itself need not be composed of mineralized material. Commonly used materials found herein include metal and synthetic resin.

SEE OR SEARCH THIS CLASS, SUBCLASS:

2.24, for coating processes relating to implantable fingernail or toenail or hair prostheses and other implantable soft tissue, such as implantable eye or vision related prosthesis, cartilage, ligament, muscle, or internal organ.

2.29, for coating processes relating to non-permanently implantable or nonimplantable dental products, such as denture appliances or temporary orthodontia devices.

SEE OR SEARCH CLASS 428, Stock Material or Miscellaneous Articles, for prostheses lacking significant structure (i.e., constituting stock materials).

433, Dentistry, for dental prosthesis or appliance or for methods normally performed by a dentist, especially

167+, for, per se, dental prosthesis article having significant structure (i.e., not merely a stock-material); and subclasses 215+ for repairing or treating natural teeth.

523, Synthetic Resins or Natural Rubbers, for solid polymer containing compositions or process of preparing; see

105+, for nonmedicated composition or process of preparing, which is specifically intended for contact with living animal tissue (other than apparel), such as a prosthesis composition or a composition for use as tooth or bone replacement, restorative, or implant.

528, Synthetic Resins or Natural Rubbers, cross-reference art collection 950 for synthetic resins of any type of the Class 520 series which is intended for use in replacing or restoring partially or wholly hard tissue as normally found in animals (e.g., dentures, bones), and excluding synthetic hair or skin and contact lenses. (Note that polymers which are a part of a composition are found in Class 523.)

623, Prosthesis (i.e., Artificial Body Members), Parts Thereof, or Aids and Accessories Therefor,

10, for ear or nose prosthesis and subclasses 16+ for implantable bone prosthesis having significant structure (i.e., other than merely stock-material).
