Dental prosthesis and moulding method
A dental prosthesis is disclosed includes a prosthetic tooth element comprising ceramic and a veneer located on a surface of the prosthetic tooth element, the veneer comprising cured dental composite. The prosthetic tooth element can be fixed to a mount in a patient's mouth using the same dental composite used for the veneer. A method of forming a prosthetic tooth element is disclosed including filling a mould that is formed at least partially from flexible polymeric material with a dental mixture comprising ceramic, and applying pressure to the filled mould to form a prosthetic tooth element comprising ceramic with a roughened surface.
Attachment system for removable dental prosthesis and dental implant abutment
A dental prosthesis attachment system is for an endosseous dental implant. The dental prosthesis attachment system includes: a removable dental prosthesis; a dental prosthesis portion secured to the removable dental prosthesis; and a dental implant portion securable to the dental implant and removably engageable with the dental prosthesis portion. The dental prosthesis portion includes an open-ended dental prosthesis sleeve having an outer surface and an inner cavity. The outer surface is secured to the dental prosthesis and the inner cavity is lined with a retention material defining an inner peripheral wall having at least one of a protrusion and a recess. The dental implant portion includes an attachment pillar removably insertable within the inner cavity of the dental prosthesis portion. The attachment pillar has a peripheral wall provided with at least one of a protrusion and a recess removably interlocked with the at least one of the recess and the protrusion on the inner peripheral wall of the inner cavity.
Implant-supported dental prosthesis, removal device for automatically removing the prosthesis, attachment piece for attaching the prosthesis to implants and implant splinting bar for attaching the prosthesis to implants
An implant-supported dental prosthesis, removal device for automatically removing the prosthesis, attachment piece for attaching the prosthesis to implants and an attachment bar for attaching the prosthesis to implants. The prosthesis comprises a compartment with a spacing member that can be actuated through a side opening by means of the device, for automatically removing the prosthesis. The device comprises a head with a first plunger configured for being introduced in the compartment and moving the first plunger in both directions to move the first plunger out when the spacer moves, causing removing the prosthesis, and when the first plunger moves in the opposite direction the head is extracted from the compartment. The attachment piece and bar for attaching the prosthesis respectively comprise a projection and a step to make it easier to remove the prosthesis.
METHOD FOR CONSTRUCTING AT LEAST ONE DENTAL PROSTHETIC PART OR A BRACKET HAVING AT LEAST ONE ADHESIVE SURFACE
The invention relates to a method for contructing at least one dental prosthetic part (20) or a bracket, with at least one adhesive surface (2), in which a 3D model (1) is made of the dental prosthetic part (20). Recesses (3,9,12,15,29,31) are constructed on the adhesive surface (2) of the 3D model (1).
Method of manufacturing an article
A method of manufacturing an article, comprising taking an article formed in an initial state via an additive manufacturing process and performing a second manufacturing process to transform the article into a second state, which comprises mounting the article in a holding device, processing at least one first feature on the article, which comprises processing at least one set of mounting features on the article, re-mounting the article via the at least one set of mounting features, and then processing at least one second feature on the article.
Denture Removal Tools
A tool and set thereof providing for relatively easy removal of dentures is described. At least one embodiment comprises a set of tools: one for removal of an upper denture; and a second for removal of a lower denture. Each are characterized by a cylindrical shaft that has a flat or facet formed near its distal end that tapers towards the distal end thinning the shaft. The tip is bent to about a 90 degree angle. The thin tip can be easily maneuvered over a lip of a denture and as necessary in-between the denture lip and the underlying gum. The user holding onto the handle on the proximal end of the tool can push, pull, leverage and rotate the tip to pop the denture loose for removal.
DENTAL PROSTHESIS
A dental prosthesis is provided, manufactured from a one-piece or multi-piece prosthesis blank which is composed of a gum-colored material (14) and a tooth-colored material (14), especially each one being based on plastic material. The tooth-colored material (14) of the blank (10) has a diameter or a width of more than 5 cm and especially a substantially flat cylindrical shape with a diameter/height ratio of more than 2:1, preferably more than 3:1. The gum-colored and tooth-colored materials (14, 12) are bonded together by bonding, polymerization and/or integral production. The boundary (16) between the materials, as viewed in the direction of the dental arch course, is wave-shaped with alternating grooves and ribs (22, 24), and in the region of the anterior arch in the vestibular directionis of radiant shape. The boundary (16) between the tooth-colored and the gum-colored material (12,14), as viewed from distal to mesial direction across the course of the dental arch, undulatingly rises towards the gum-colored material, with an average inclination of 20 degrees or more. The tooth-colored material (12) has a greater gingival occlusal height in the molar region (30) than in the anterior region (32).
METHOD FOR CONSTRUCTING A RESTORATION
The invention relates to a method for constructing a restoration (1), in which a dental situation (3) is measured by means of a dental camera (2) and a 3D model (4) of the dental situation (3) is generated. In this case, a computer-assisted detection algorithm is applied to the 3D model (4) of the dental situation (3), wherein a type of restoration (17) and/or at least a tooth number (18) and/or a position of the restoration (1) to be inserted are automatically determined.
Dental all-ceramic restoration and manufacturing method thereof
A dental all-ceramic restoration and manufacturing method thereof; the outer surface of the dental all-ceramic restoration has neither visible marks remaining from the removal of the connecting bars (7) nor local grinding traces and chipping, and is smooth with uniform structure. The manufacturing method thereof is wet-forming or milling. No connecting bars are needed to connect the dental restoration bodies (3) with a surrounding mould blank or ceramic blank. This eliminates the need for manually cutting off the connecting bars (7) to separate the forming body from the surrounding ceramic blank, further grinding and polishing process to treat the excessively rough outer surface, and thereby reducing the risk of chipping and premature failure. In the manufacturing processes thereof, the hardened ceramic green body (2) made by wet-forming technique has more homogenous microstructure and less particle packing defects than the dry-pressed blanks and partially sintered blanks. Furthermore, higher surface smoothness can be obtained by milling unsintered hardened ceramic green body than by milling partially sintered blanks. The dental all-ceramic restoration has a high degree of surface finish, and can be directly used without polishing, veneering or glazing.
BONE-MOUNTED DENTAL ARCH VENEERS AND METHODS FOR FABRICATING AND UTILIZING THE SAME
Bone-secured dental arch veneers and methods for fabricating and utilizing the same. The dental arch veneers include a veneer assembly having one or more tooth veneers and a support structure configured to support the tooth veneer(s). The dental arch veneers also include a coupling structure configured to interconnect the veneer assembly to a bone mount that is anchored along a user's maxilla or mandible. The coupling structure also is configured to permit the veneer assembly to be selectively and repeatedly interconnected with and disconnected from the bone mount. The methods include determining a target region within the user's mouth, obtaining a representation of the target region, manipulating the representation to create a desired arrangement of the user's teeth within the target region, determining anchoring positions proximate the target region for anchoring the bone mount, and forming the dental arch veneer based on the anchoring positions and the desired arrangement.
