A dental bulk block for a CAD/CAM machining process. The dental bulk block is a glass-ceramic block having a crystalline phase embedded in an amorphous glass matrix. The crystalline phase includes lithium disilicate as a main crystalline phase, no sub-crystalline phase exists, and the crystalline phase has a mean grain size of 0.01 to 1.0 μm and a crystallinity degree of 25 to 45%. The dental bulk block can improve machinability during cutting such as CAD/CAM machining in the state of a high-strength workpiece with high flexural strength, thereby reducing a tool resistance and a wear rate, increasing a tool life span, and reducing edge chipping during a machining process. In addition, a dental restoration with desired translucency variations can be manufactured through a simple process of machining a block and altering post-heat treatment conditions, and thus can be realized with various shades.

Provided is a method of forming a customized alveolar bone tissue. The method includes obtaining first data having image information corresponding to an original alveolar bone of an alveolar bone defect, obtaining second data having image information on a defective portion of the alveolar bone defect, calculating third data having image information on a barrier membrane covering the alveolar bone defect by using the first data and the second data, and forming a barrier membrane artificial tissue corresponding to the barrier membrane by using the third data.

An implant to retain facial or dental prostheses includes a bone-engaging portion, a transmucosal portion, and an abutment portion. The bone-engaging portion of the implant includes a longitudinally extending distal portion formed of a conformal microscale cell structure and, optionally, a non-biological coating. The transmucosal portion includes a plurality of micro holes. The abutment portion of the implant may be polished to a mirrored or super-mirrored finish.

A dental restoration system (1) for restoring a tooth at least during healing of an implant construction (5) being set into a jaw of a patient comprises a crown abutment (3) and a locking member (2). The crown abutment (2) is configured to be positioned on a gingiva former (4) mounted to the implant construction (5). The locking member (2) has a contact face (212) and a fixing structure (24) configured to be fixed to the gingiva former (4). The crown abutment (3) has a through hole (31) configured to receive the locking member (2) such that the contact face (212) of the locking member (2) contacts the crown abutment (3) and the fixing structure (24) at least partially extends out of the crown abutment (3). The crown abutment (3) is made of an abutment material configured to bond with a crown material used to build a crown (6).

The present invention relates to a system and method for dental implant and restorative services. By locating the key functions at one physical location, dental implant services are efficiently provided to patients. These functions include a treatment coordinator, a direct marketer, a restorative doctor/prosthodontist, a surgeon, an imaging area, and a dental laboratory, Further, services for dentate patients are improved by utilizing advanced dental implant methods and systems. These methods and systems include both model-based services and CT (computed tomography) guided surgery services. Using these services, improved surgical guides for dental implants are constructed.

Methods of manufacturing dental prosthesis/implants each to replace a non-functional natural tooth positioned in a jawbone of a specific pre-identified patient are provided. An example method includes the steps of receiving imaging data such as x-ray image data and surface scan data of a dental anatomy and/or a physical impression of the dental anatomy of a specific preidentified patient. The steps can also include forming a three-dimensional virtual model of at least portions of a non-functional natural tooth positioned in the jawbone of the specific pre-identified patient based on the imaging and surface scan data, virtually designing a dental implant based upon the virtual model, exporting the data describing the designed dental implant to a manufacturing machine, and custom manufacturing the dental implant for the specific patient.

Devices and methods to perform measurements of body analytes, like glucose, using a bone implant and/or a dental implant and/or a jawbone implant and an analyte measuring component. The dental implant can have a protruding component that protrudes to the oral cavity for many years and therefore enable long-term handling of the analyte measuring component and long-term monitoring of the analyte. The new device enables for example, to replace at least part of the analyte measuring component, to replace materials of the analyte measuring component and the energy source of the device without surgery.

The invention relates to magnesium screws and screw-like devices for dental implant surgery and, more particularly, to magnesium and magnesium-based tenting devices for implementation in periosteal and gingival tissue overlying an alveolar ridge of a mandible or maxilla to provide vertical ridge augmentation, i.e., bone regeneration. The tenting devices may be composed of magnesium in dry form, such as metallic magnesium and salts thereof; or magnesium alloy including magnesium in dry form and at least one alloying element or compound; or magnesium-polymer composite including magnesium in dry form and at least one polymer.

An implant abutment according to the present invention is a dental implant abutment with an enhanced shock distribution function, the dental implant abutment comprising: an upper coupling portion that is an upper portion coupled to an artificial tooth; a lower coupling portion that is a lower portion coupled to a fixture, and an exposed portion that is exposed to the outside between the upper coupling portion and the lower coupling portion and has a plurality of flow grooves. By forming a plurality of grooves in the exposed portion of the implant abutment, the exposed portion of the implant abutment performs a shock distribution function as if it shakes elastically and distributes an occlusal force of teeth exerted to the implant, thereby providing a buffering function of relieving an impact on an area where the implant is inserted.
