A dental bar is disclosed for accurately determining the separation and relative orientation of two coping cylinders projecting from dental implants in a patients mouth to receive a prosthesis. The dental bar comprises two sockets, for fitting over and securing to the two coping cylinders, connected to one another by a limb formed of telescopically collapsible sections. The telescoped ections of the limb are of differing cross-sectional shape so as to define between them a volume into which a bonding material may be injected through a port, in order to lock all the limb sections permanently relative to one another.

Disclosed is a method for providing a dental abutment by using data about a customized abutment, comprising the steps of: receiving oral data about a patient; and acquiring a standardized abutment from a standardized abutment group generated from the customized abutment in correspondence with the inputted oral data about the patient.

An external drive apparatus for bendable collar implants includes a male fastener and a female driver. The male fastener is constructed as a rigid and integral unity including an implant screw, a collar, and a male screw-top drive. The female driver supports a female screw-top drive. The female driver is configured for application of an implantation torque to the implant screw via the male screw-top drive which is disposed distally away from the collar.

The invention relates to a white, bacteria-resistant, biocompatible, adherent coating for an element which can be integrated in hard and soft tissue, in particular an implant, a screw or a plate, having a structure made from metalliferous gradient layers having varying oxygen content, wherein the band gap of the outer-most gradient layer is greater than 3.1 eV, wherein the outer-most gradient layer is crystalline and wherein the gradient layers comprise tantalum and/or niobium and/or zirconium and/or titanium.

A root portion of a root-analog dental implant may include a core positioned in an approximate center of the root portion of the dental implant. The core may provide mechanical strength and/or support for the dental implant and may include one or more struts. The root-analog dental implant may further include a porous surface positioned on a portion of a vertically oriented exterior surface of the core. The struts may be configured and arranged to provide mechanical strength and/or support for the root-analog dental implant.

The method of detection of positioning of a dental implant for dental restoration involves taking a manual or digital impression of the buccal space, including a cicatrisation element secured to the implant and having an emergent surface outside the gum, and automatically detecting the positioning of the implant by identifying (i) the axis of the implant corresponding to an axis of the cicatrisation element identified by the geometry of the emergent surface or association with a cicatrisation element memorized in a database; (ii) the orientation of the implant by the orientation of the emergent surface or association with a cicatrisation element memorized in a database; and/or (iii) the height of the implant by the height of the cicatrisation element, for example based on a color or an indicator of the emergent surface or association with a cicatrisation element memorized in a database.

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.

A bone cement includes a liquid component including a monomer configured to polymerize upon curing of the bone cement; and a solid component dispersed in the liquid component, the solid component including a powder of a polymer; an initiator; and a powder of a piezoelectric ceramic. A cell culture dish includes a base; and walls connected to the base to define an interior of the cell culture dish, wherein at least a portion of an interior surface of the base includes a piezoelectric material.

One or more specific embodiments disclosed herein includes a dental apparatus comprising a prosthesis, an implant fixture, a multi-unit abutment comprising a clocked projection and a conic section, and an adjustable locking device. The adjustable locking device may comprise a washer, a first pyramidal element, plurality of expansion segments each comprising a plurality of bottom planar surfaces and a plurality of top planar surfaces, a second pyramidal element comprising a second plurality of angled planar surfaces and a convex upper surface, a central retaining screw that threadingly engages the multi-unit abutment, and an O-ring, wherein the O-ring engages each of the plurality of expansion segments.

Disclosed are a fixture for a dental implant and an implant system comprising the same. The implant system of the present inventive concept comprises: a first fixture having a first body part and a first continuous screw part which is formed in a spiral around the outer circumferential surface of the first body part and is formed continuously without a break; and a second fixture having a second body part that is identical to the first body part, and a second continuous screw part which is formed in a spiral around the outer circumferential surface of the second body part and which has an outer diameter that differs from that of the first continuous screw part. The present inventive concept allows implant operations to be carried out in a more straightforward fashion than hitherto since, even if initial fixture placement fails, a subsequent fixture can be placed straight away without any further drilling work.
