Systems and methods for sterile delivery of prostheses that protect refined and/or conditioned surface properties and thereby reduce aging of surface properties in prostheses. An example of the system includes a partially custom-shaped holder that also serves as an insertion tool that holds a customized dental prosthesis in a pre-defined position inside a titanium container that is hermetically sealed. Container materials serve as a getter or catalyst with respect to the osseoconductive surface. An example of the method includes laser welding to hermetically seal a metal container as packaging for a prosthesis with a metal foil, and the sterilization of the packaged and sealed prosthesis with dry heat.

The present disclosure belongs to the field of biological materials, and particularly relates to a multilayer zirconia ceramic with uniform transition and a method for preparing the same. The specific technical solution of the present disclosure is as follows: a zirconia ceramic with a formula comprising, in percentage by mass, 0-3% of lanthana, 1.5-16% of yttria, 0-2.5% of silicon carbide nano-whiskers, and 0-1.5% of a coloring agent, the balance being zirconia. Correspondingly provided are a multi-layer zirconia ceramic with uniform transition prepared using the formula and a method for preparing the same. By using the method of the present disclosure, multilayer zirconia ceramics with good and uniformly transitioning core properties can be quickly and conveniently prepared, meeting the requirements of patients with dental disorders on the use and esthetics of dentures.

A dental implant has an implant body made of diamond material, the implant body being provided with a bore hole that has at least one lateral dimension and a depth dimension, the lateral dimension and the depth dimension being mm sized. The bore hole is substantially formed by laser light being directed at the implant body to form said bore hole by softening said diamond material at an intended location of said bore hole. The bore hole is further defined by utilizing at least one metallic drilling tool to remove more of the diamond material after initial formation of the bore hole by said laser light. Preferably, the drilling tool has a cone shaped drilling head or a rectangular drilling head.

A method of correcting an axial position of a workpiece support (1) used 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 form fitting manner.

A dental stent for tooth restoration, includes an acrylic outer shell and a set of metal matrix separator strips partially embedded into an inner silicon bed. A method of manufacturing a dental stent includes 3D printing of a model wherein tooth forms of teeth to be restored are individually removable from a remainder of the model. A method of tooth restoration uses a dental stent, and a kit of parts including a dental stent and a composite resin, and optionally a heater, a light cure unit, and a finishing tool kit.

Dental implants may be designed using a three-dimensional scan of an extracted tooth root and/or a corresponding socket site. The dental implant may include a root portion designed to sit below the patient's gum line, a connector portion positioned above the root portion and designed to sit above a rim of a socket site and/or gum line, and an abutment portion positioned above the connector portion upon which a crown may be placed. The root portion may include three sections that correspond to three areas of a three-dimensional scan of an extracted tooth root. The first and third sections of the implant may have a size and shape that corresponds to a first and third portions of the three-dimensional scan, respectively. A circumference of the second section of the implant may be smaller than a corresponding circumference of the second section of the three-dimensional scan of the tooth root.

Dental devices and systems and methods for making the same are provided. In at least one embodiment, a method for fabricating an arch-shaped device for coupling to a patient's mouth is provided. The method can include adjusting a denture form device to conform to a shape and fit of a patient's mouth. The method can also include using the denture form device to obtain an impression of the patient's mouth. The method can also include selecting an arch device and adapting that arch device to conform to a model of a patient's mouth. The method can also include a denture form device that can be combined with the arch device to form a complete denture.

An impression taker captures an impression of preparation cut in abutment teeth. The impression taker includes; a rigid body supporting a first arm and a second arm. The first arm has a first longitudinal end configured to take an impression of a preparation cut in a first abutment tooth, and the second arm has a second longitudinal end configured to take an impression in a second abutment tooth. In addition, a reinforcement combination supports a dental bridge and an elongate proximal bar supports a dental bridge. The impression taker and the reinforcement bar combination can be used to produce a direct dental bridge.

The present invention relates to a method for the design and manufacture of a dental component with a surface, wherein a 3D model of the dental component is designed by means of a CAD unit and the dental component is manufactured by a CAM unit on the basis of the 3D model. In order to provide a method which significantly shortens the time required for the design and manufacture of a dental component, so that the length of the dental session at which the patient must be present is shortened, it is inventively proposed that the 3D model is manufactured in at least one first design step, in which a first 3D submodel is designed with at least one first surface section, and a second design step in which a second 3D submodel is designed with at least one second surface section, wherein the first design step is completed before the second design step and the CAM unit begins the manufacture of the first surface section of the dental component based on the first 3D submodel before the design of the second 3D submodel is completed.

The present invention relates to a polymerizable composition, which comprises (a) at least one radically polymerizable oligomer, (b) at least one radically polymerizable monomer and (c) at least one initiator for the radical polymerization, characterized in that the radically polymerizable oligomer (a) is selected from the group consisting of aliphatic urethane (meth)acrylate oligomers, epoxy (meth)acrylate oligomers and polyether urethane (meth)acrylate oligomers, and the radically polymerizable monomer (b) is polyfunctional.
