A61C - Definition
This subclass covers:
Apparatus (i.e. instruments, implements, machines, structures, tools) or processes that are specially adapted for, or limited to use in, creating artificial teeth, mounting artificial teeth, supporting artificial teeth, or repairing artificial teeth or their supports (e.g. denture articulators), and wherein the dental prostheses made or fixed by the apparatus or process are used exclusively for humans or both humans and animals.
Apparatus or methods utilized to prevent, discourage, or cure oral diseases (i.e. diseases occurring exclusively within the oral cavity such as enamel caries or periodontitis) in humans or both humans and animals.
Apparatus, devices, or methods used for one or more of the following:
Apparatus (i.e. instruments, implements, machines, structures, tools) or processes that are specially adapted for, or limited to use in, the treatment, reconstruction, removal, insertion, replacement, repair, transfixing or testing of either natural teeth, artificial teeth that are permanently affixed within the oral cavity, gums, or other portions of the oral cavity having an effect on their operation (e.g. portions of jawbone supporting teeth), and wherein the apparatus or processes are used exclusively for humans or both humans and animals.
Apparatus, devices, or methods used for
Dental prostheses devices or artificial dental implant devices per se or their components (e.g. artificial teeth, mounting or attaching means for artificial teeth, devices for supplementing jawbones, crowns) used within the oral cavity.
Dental implants formed from biological material or consisting of oral cavity parts originating either from a donor source or from the patient that are intended to be introduced, or reintroduced, into the patient’s oral cavity to correct a dental or oral hygiene problem (e.g. modified natural teeth or jawbone material from a donor).
Adjunct, auxiliary, or supplementary means or structures that contribute to the effectiveness or safety of dental procedures or their products and are specially adapted to be used either:
Specially adapted components of apparatus having structural features limiting them to use with at least one of the dental apparatus types specified above (e.g. dust collectors, illumination devices).
Accessories specially adapted for use with at least one of the above types of apparatus, means, or structures (e.g. devices for measuring the length of the root canal of a tooth).
Relationship between large subject matter areas
Subclass A61C(this subclass) provides for devices used by others to clean an individual’s teeth. It also provides for devices used by individuals upon their own teeth to remove foreign matter from the surface of their teeth or enhance the appearance of their teeth when the device is not specifically provided for elsewhere.
Subclass A46Bcovers manually moved or powered brushes, and in particular toothbrushes, used for cleaning that are not specifically provided for elsewhere. It also covers arrangements of brush bristles per se and the handle structure for brushes.
Subclass A61Dcovers devices used by individuals to remove foreign matter from the surface of the teeth of animals or enhance the appearance of the teeth of animals when the device is not specifically provided for elsewhere and is limited to use solely on animals.
Subclass A61Kcovers preparations that are used for medical, dental, or cosmetic purposes in the oral cavity.
