A device for making artificial teeth for a denture. The device is comprised of a nest comprised of a lower portion formed of a rigid material and having an upper planar surface, and an upper portion contiguous with the upper planar surface of the lower portion, and formed of an elastomeric material and configured to receive a plurality of the artificial teeth and hold the teeth in predetermined positions relative to the upper planar surface. A method for making artificial teeth using the nest and a fixative applied thereto is also disclosed. The method may include milling of the artificial teeth by a CAD-CAM operated mill.

Root canal abutment devices and methods which facilitate the adjustment or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured within a pulp chamber of a pre-existing tooth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy sleeves or plates or elements extending along the abutment. Each of the sleeves has a length with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion flattens to allow for the oral appliance to be placed thereupon while removal of the energy allows the elements to reconfigure into its curved configuration thereby locking the oral appliance to the abutment. Removal of the oral appliance may be effected by reapplication of energy to the elements.

A carbon coated filament cord for marking the sidewall of dental prostheses. The carbon coated filament cord is made up of a strand of filaments having a core and a marking coating placed around a circumference of the core along the length of the strand of filaments. The diameter of both the core and the marking coating is sized to fit within an interproximal spacing between teeth and dental prostheses such as crowns, bridges or onlays. When pressure is applied to the strand from the tooth and adjacent prosthesis, an easily identifiable mark is left on the sidewall of the prosthesis at that position, allowing a dental professional to easily locate the area that requires further work.

A method and apparatus form a tooth positioner for repositioning at least one tooth of a patient and provide a dental arch cast of a patient, separate at least one tooth from the dental arch cast, fix a pin in a stump part of the at least one separated tooth, and in any non-separated teeth, reconstruct the dental arch cast of the patient by aligning the separated teeth to correspond to the alignment in the patient's mouth and hold the pins in a material that may be softened, soften the material, apply force to the pin fixed in the at least one tooth to be repositioned to move it in a desired direction to obtain a realigned arch, and form a tooth positioner corresponding to the realigned arch. The tooth positioner is used by having the patient wear it for a period of time.

The present disclosure is directed to an expanding bone implant and, more particularly to an oral implant having radially extendable anchoring means.

Casting jigs, methods, and kits that may be used in manufacture of anatomical healing caps. A casting jig may include a body having one or more wells within the body, each well being open at a proximal end thereof and having a negative shape corresponding to an anatomical healing cuff body of a given tooth position. Each respective anatomical healing cuff body negative shape includes an asymmetrical cross-section and an irregular surface so that an anatomical healing cuff body having said shape is configured to provide substantially custom filling of at least an emergence portion of a void where a natural tooth once emerged or should have emerged from the void (e.g., in the case of a congenitally missing tooth). The casting jig may further include a socket at a distal end of each well that is configured to receive therein a dental implant or dental implant analog.

A workpiece support (1) for removing material from a dental workpiece (2) which is held by the workpiece support (1) and is rotated together with the workpiece support (1) about a drive rotation axis (3) when material is being removed. The workpiece support (1) has at least two workpiece support parts (4, 5, 6) which can be separated from each other and connected to each other. One of the workpiece support parts (4, 5) has at least one compensation region (7) with a material projection (8) for introducing a compensation surface (9) by removing material, and the other workpiece support part (6) has a seating surface (10) for connecting to the compensation surface (9) in a formfitting manner.

The present invention extends to a dental appliance having a set of rigid flanges conforming to a patient's mandibular bone structure and a stabilizer for securing and resisting movement of the dental appliance once set. The stabilizer reduces movement of a lower denture. The stabilizer extends perpendicularly from a flange of the lower denture and reduces denture movement during chewing. The stabilizer has one surface making contact with the bottom of the tongue and another surface making contact with the Genioglossus muscle when a user is chewing. The stabilizer does not require a dental implant for maintaining lower denture stability.
