An oral appliance including an upper body having an upper body channel to receive a maxillary dentition of an upper dental arch, a lower body having a lower body channel to receive a mandibular dentition, and at least one node disposed on the lower body base outer surface to engage the upper body outer surface upon receipt of the maxillary teeth of the upper dental arch in the upper body channel and the mandibular teeth of the lower dental arch in the lower body channel.

A molded breathing appliance for supporting a nasal oxygen tube having an upper bite rim, a lower bite rim, a moldable material disposed within the upper bite rim and lower bite rim for conforming to a patient's maxillary bite impression and mandibular bite impression, respectively, an L-shaped member extending outwardly perpendicular to the upper bite rim, and a transverse support disposed on the L-shaped member and configured with a plurality of sets of oxygen tube finger clamps to retain a nasal oxygen tube in proximity with a patient's nostrils.

Example dental methods involve using a marker transfer jig that captures the location of one or more fiducial markers on a patient's jaw and then helps position an alternate marker, tool, fixture or some other chosen device on a cast model of the patient's jaw. The cast model with the attached alternate marker, tool, fixture or other chosen device is radiographically scanned and analyzed to aid in various orthodontic and other dental treatments.

A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. A central portion not configured to flex is situated between housing side walls. Each such side wall has an upper side portion and a lower side portion. Without the lock a squeezing force on the upper side portions flexes the lower side portions outward. The lock urges the upper side portions outward so as to flex the lower side portions inward. The lock reduces or eliminates freedom of movement of the tray. The system allows rapid removal and is sturdy enough to withstand forces including from various angles and leverage. The central portion may hold registration elements.

A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. Housing side walls are joined to a cross member that has a flexion region on each side of the housing, each side wall having an upper side portion and a lower side portion. Without the lock a squeezing force on the upper side portions flexes the lower side portions outward. The lock urges the upper side portions outward so as to flex the lower side portions inward, thereby urging the material, once hardened, against the teeth. The lock reduces or eliminates freedom of movement of the tray. The system allows rapid removal and is sturdy enough to withstand forces including from various angles and leverage.

Molds for fabrication of custom and potentially modifiable abutments and impression posts for dental implants with various degrees of angulations (including zero degrees) and various dimensions are provided, with a generally oval shape that expands laterally upwards, a symmetrical or asymmetrical cross-section, and regular surfaces, that are fabricated as one piece, or as two coupling pieces snapping onto each other. Custom abutments achieve the development of a custom gingival emergence profile, three dimensionally, which is potentially modifiable according to the needs of each particular clinical case. Custom impression posts that correspond in dimensions and angulations to the abutments allow the accurate recording and transfer of the developed gingival emergence profile from the mouth onto the working cast, where the final implant prosthesis is fabricated. Custom abutments and impression posts have properties and design that allows their preparation and usage as temporary abutments for the cementation and support of temporary prostheses.

The present invention relates to methods of producing and deploying orthodontic brackets (2a) or attachments.

A system and method for fabricating dental crowns and bridgework includes the steps of: selecting one or more model teeth; forming a mold around the model tooth using a soft flexible material; removing the model tooth from the mold; adding wet dental restoration material to the mold and vibrating the mold; pressing framework into the wet restoration material; vibrating the mold and removing moisture; allowing the restoration material to dry and removing the molded crown or bridgework from the mold; trimming off excess restoration material and adding restoration material to the margin area as needed; baking the crown or bridgework in an oven without the mold and removing the crown or bridgework from the oven when the restoration material is at least partially cured.

A method for making a set of dentures comprises a providing step, a mandibular impressing step, a first maxillary impressing step, a tray fabricating step, a second maxillary impressing step, a bite registering step, and a denture fabricating step. Optionally, the method further includes a bending step, a lifting step, a posterior molding step, a removing step, and/or an anterior molding step.

A custom denture tray for fabricating a set of dentures that includes an upper tray that includes a baseplate. The baseplate has a top side configured to hold material for capturing a dental impression. A bite block is attached to a bottom side of the baseplate. The bite block is made of a relatively soft material which can be marked to show positions for artificial teeth to be placed in the dentures. In particular embodiments, the denture tray includes a removable handle configured to be attached to a front portion of the mouthpiece. The removable handle may be attached so that it protrudes from a user's mouth when the mouthpiece is in the user's mouth.
