摘要： A method for designing dentures according to which artificial teeth can be easily and accurately attached to a denture base, which is designed and shaped by CAD/CAM, when the artificial teeth are arranged on the denture base is provided. The method for designing a denture (10) on a computer based on data on an intraoral shape comprises: creating data on a shape of a denture base (20) based on the intraoral shape (S22); creating data on a position of an artificial tooth (30) to be arranged on the denture base (S23); and creating data on a shape of an occlusal guide (40) that is tabular and has a recess part corresponding to a shape of the arranged artificial tooth in an occlusal surface side (S24).

摘要： Dental restoration holding devices, dental restoration holding assemblies including the same, and associated methods. A dental restoration holding device includes a base portion and a cap portion, and is configured such that the base portion and/or the cap portion engages a flexible support sheet to define a support surface that supports a dental restoration relative to a suction tip. A dental restoration holding assembly for supporting a dental restoration includes the dental restoration holding device in combination with the flexible support sheet and the suction tip. A method of treating a dental restoration includes operatively engaging a flexible support sheet with a dental restoration holding device to define a support surface, placing a dental restoration upon the support surface, engaging a suction tip with the dental restoration holding device, and flowing a treatment fluid through the dental restoration holding device.

摘要： A base shaft 4 with a built-in magnet is rotatably projected on a base 1. A rocking body 7 has a square substrate 8, a sphere 9, a sphere holder 10 rotatable around an axis which extends through the center of the substrate and perpendicular to the substrate, and a stopper for fixing the sphere holder at a desired rotational position. The sphere holder holds the sphere in such a way that the sphere is fixed at a desired rotational position. A stage is attached to the sphere through a support rod 20. A lower portion of the sphere protrudes downward from the sphere holder and substrate. The rocking body is magnetically coupled to the base shaft at a lower end of the sphere. An elevating body 21 is fitted on the base shaft and fixed by a set collar 22 at a desired height. The elevating body has a recess for receiving the lower portion of the sphere. The rocking body takes a horizontal position when the elevating body is brought into contact with the substrate of the rocking body, but takes a tilt position when a side of the substrate is brought into contact with an upper surface of the elevating body after the elevating body is lowered. An angle display mechanism 23 displays a tilt angle at the tilt position of the rocking body depending on the height of the elevating body.

摘要： A device for determining the relative positions of an upper and lower jaw has an upper carrier with an upper contact surface for the upper jaw and a lower carrier with a lower contact surface for the lower jaw, wherein the carriers in a position of use correspond to the device with an upper jaw and a lower jaw. In addition, the device has a system for detecting the relative spatial positions of the upper and lower carriers with respect to one another.

摘要： A method for producing a prosthesis or partial prosthesis based on digital data, using multiple teeth present in a dental arch (14) and a prosthesis base to be produced. The prosthesis base is rough-milled by a milling tool, i.e. is milled in a first step, and the prosthesis base present as a semi-finished product, in particular in regions of the prosthesis base on which the teeth and the prosthesis base abut against each another and/or are to be bonded to each other, is partially milled, i.e. is milled in a second step, by a different milling tool, thereby being brought to a target height which corresponds to the desired bonding gap between the prosthesis base and the tooth or dental arch (14).

摘要： A method and kit for producing implant drilling guides positioned at the proper angle and orientation so as to avoid inadvertent damage to critical regions of the patient's jaw when drilling to place dental implant screws. The method works by placing a small post with x-ray visible depth markers in the root of the patient's tooth immediately after tooth extraction. This post, along with guideblocks, optional washers, reduction or expansion guides, and rapidly hardening guide materials (such as acrylics or thermosetting materials) is used to construct a removable guide that anchors to the patient's adjacent teeth, and preserves the location and orientation of the extracted tooth root. Once the root is filled in with new bone, the guide, in conjunction with the X-ray post depth information, can be used to direct drilling along the same route as the old tooth root, thus avoiding critical structures.
