Methods of conducting object-related procedures and associated system involve a secure and physical interaction being formed between a fiducial device and a site having an associated object to form a fiducial marker. A virtual plan is formed, detailing the procedure on the object at the site, in registration with and with respect to the fiducial marker. Movement of a procedure-conducting device is physically regulated with a guidance device responsive to a controller device and with respect to the fiducial marker. The guidance device physically regulates movement of the procedure-conducting device, according to the virtual plan and corresponding with physical manipulation of the procedure-conducting device by the user, to conduct the procedure. Tactile feedback is provided to the user, via the procedure-conducting device, if the physical manipulation by the user causes the procedure-conducting device to deviate from the virtual plan.

This invention is a classic dental cow horn explorer that has been fitted with dycal style balls on the ends, for a completely new instrument designed to facilitate exacting placement of cavity liners and bases, spreading flowable composite underneath fillings by the Dentist, and placing Interim Therapeutic Restorations (ITR) such as fluoride releasing glass ionomer by the Dentist or Registered Dental Hygienist Expanded Functions (RDHEF).

Doctors then can reach over matrix bands and apply dental bases and liners, or spread flowable composite directly to the axial wall and pulp floor of their preps, and RDHEF's can access hard to reach interproximal, root and furcation areas to apply glass ionomer or other Interim Therapeutic Restorations where incipient caries have been hand excavated.

A medical apparatus including a bar with a first attachment loop, a second attachment and a plurality of hooks, wherein the medical apparatus is an arch bar.

The present invention relates to a dental composition comprising a specific polymerizable compound and a polymerization initiator system. Furthermore, the present invention relates to the specific polymerizable compound as such and its use in a dental composition. The specific polymerizable compound of the present invention has an N-allyl (meth)acrylamide group, which nitrogen atom is substituted with an alkyl or alkenyl group optionally substituted by a group selected from a hydroxyl group, a C.sub.1-4 alkoxy group, a tertiary amino group and a carboxyl group, wherein 1 to 8 carbon atoms in the main chain of the alkyl or alkenyl group may independently from each other be replaced by a heteroatom selected from an oxygen atom and a sulfur atom.

Actuator systems for oral-based appliances utilizing transducers which are attached, adhered, or otherwise embedded into or upon a dental or oral appliance to form a hearing aid assembly. Such oral appliances may be a custom-made device which receives incoming sounds and transmits the processed sounds via a vibrating transducer element. The transducer element may utilize electromagnetic or piezoelectric transducer mechanisms and may be positioned directly along the dentition or along an oral appliance housing in various configurations.

The invention relates to a dental splint as an assembly comprising a first subassembly embodied as a dental splint body and having a surface that comes into contact with an oral cavity of a user, a second subassembly embodied as electronics, at least one third subassembly embodied as a sensor, a fourth subassembly embodied as an energy source, at least one fifth subassembly embodied as an antenna, and a sixth subassembly embodied as electrical connection means, wherein the second to fifth subassemblies are connected by the sixth subassembly. In this case, at least one of the second to sixth subassemblies is produced in each case completely or partly in a 3-D printing method.

A method of automatically producing or reproducing a customized AGP (Anterior Guidance Package) equipped splint for a patient with or without a severe malocclusion is provided. The method of automatically producing or reproducing an AGP equipped splint according to current invention comprises of combining Virtual Articulation, CAD (Computer Aided Design)-CAM (Computer Aided Manufacturing) method with AGP and special retentive piece technology. The method of the current invention enables a patient with or without a severe malocclusion to receive his/her customized AGP equipped splint or a replacement thereof automatically without visiting the dentist again and again.
