Definition statement

This place 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:

  • correcting abnormalities or injuries that prevent the proper or desired bringing together of the cooperating surfaces of natural teeth, or their artificial replacements that are permanently affixed within the mouth, located on opposite jaws;
  • preserving or rectify the appropriate or desired relative positioning, separation gaps, or alignment of natural teeth; or
  • preventing or repairing damage to natural teeth or their appropriate or desired relative positioning, separation gaps, or alignment (e.g. devices that surround or cover teeth to prevent grinding).

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

  • sanitizing the oral cavity or dental prostheses (e.g. gargling devices, washing means);
  • removing foreign matter (e.g. food) or undesirable naturally occurring matter (e.g. plaque, calculus) from the surfaces of teeth, gums, or dental prostheses; or
  • stimulating gums.

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:

  • during dentistry procedures (e.g. saliva removers, medication suppliers, drainage treatment);
  • with the products of dental procedures (e.g. artificial teeth supports); or
  • during the making of dental prostheses (e.g. stands for impression trays).

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).

Relationships with other classification places

Subclass A46B covers 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 A61D covers 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 A61G covers dental work stands and dental or operating chairs.

Subclass A61K covers preparations that are used for medical, dental, or cosmetic purposes in the oral cavity.

Subclass A61Q covers preparations for care of the teeth, of the oral cavity or of dentures e.g. toothpastes,mouth rinses.
