An anatomical healing abutment is configured to connect to a dental implant. The healing abutment has a body portion which includes at least three reference marks that provide data to orient the connection axis of the abutment with the that of the dental implant so that certain conventional steps, including healing abutment manipulation, multiple scans, and the taking of impressions, can be eliminated, thereby saving time and effort on the part of the practitioner.

Tools and methods for expanding a precursor hole in a host material to receive a fixture. The precursor hole is enlarged by a rotary tool having helical flutes and interposed lands. The flutes have a negative rake angle. The lands each have a working edge that cuts the host material when the tool is rotated in a cutting direction, and that condenses the host material when the tool is rotated in a densifying direction. The body of the rotary tool has a stopper section that plugs the hole when a certain depth is reached. When the tool is used with a copious wash of irrigating fluid at or below the necessary depth, hydraulic pressure builds inside the precursor hole. The hydraulic pressure can be advantageously exploited in cutting mode to autograft a slurry of host material particles into the sidewalls of the hole and create an incipient densifying crust.

Compositions and methods for inhibiting and interrupting biofilm formation, and for destabilizing established biofilms are provided, the novel compositions including polymeric resins and monomeric non-polymerizable and polymerizable resins. More particularly, the compositions and methods enable the protection and removal of biofilms from surfaces in the context of medical, consumer, domestic, food service, environmental and industrial applications, where the effects constitute beneficial and desirable biofilm attenuating activity.

The present invention relates to a method and a system for managing dental article information based on a UHF RFID, and more particularly, to a method and a system for managing dental article information based on a UHF RFID, capable of automatically monitoring a location, a stock, and an expiration date of an article used by medical staffs of a dental clinic without an additional action of the medical staff, and providing information and a notification related to a dental article to the medical staffs of the dental clinic.

A dental prosthesis formed of a composition comprising a polymeric material, the prosthesis comprising one or more locating formations adapted to receive a dental implant fixture or dental abutment, the or each locating formation comprising a recess comprising a first recess portion formed in the polymeric material of the prosthesis, and a second recess portion provided in a sleeve located in the prosthesis.

The present invention discloses a connected structure of a porous surface structure and a substrate, a method for preparing the same, and a prosthesis of the same. The connected structure consists of a pre-connected or integrally formed composite body of a porous surface structure and an intermediate; and a substrate, which is connected to said intermediate to achieve the connection of said composite body to the said substrate; the composite body comprising a first composite region corresponding to a first stiffness; a remaining composite region in the composite body other than the first composite region, which at least contains a second composite region corresponding to a second stiffness; and the first stiffness is less than the second stiffness. The present invention achieves a fastened connection between the composite and the substrate and largely maintains the mechanical properties of the substrate; and it provides a prosthesis with excellent bone ingrowth properties and that the strength of the substrate is not substantially affected.

A sensory unit for implant-supported dental implants or prostheses. The main unit is composed of two or more subunits, or devices. One of the units is placed in the region of the implant head, and will have the function of transforming the mechanical forces into an electrical signal. It can also be placed in the masticatory region of implant supported bridges or overdenture, to perform the same function, i.e., transforming mechanical loads into an electrical signal. A second unit, will receive by a wired or wireless electronic communication the electrical signal, and will convert it into a neurological stimulus perceived sensorially by the sensory endings of the trigeminal nerve, unilaterally, or bilaterally. This second unit will be arranged in the submucosa, in the vicinity of the nerve ending, taking advantage of the anatomical depressions or recesses in the region, and will establish a gradient of neurological stimulation towards the nerve ending.

A dental implant identification system is provided that aids a dental professional in identifying the type of dental implant that has been surgically placed into maid lary or mandibular bone of a patient who requires restorative dental procedures. Additionally, a dental implant identification system is provided. that aids a dental professional in identifying the forensic remains of victims due to various factors and circumstances.

The present disclosure relates to a plasma treatment apparatus and a method using the same, and more particularly, to a plasma treatment apparatus for applying, to a target object, such as a biomaterial, characteristics (e.g., removal of organic materials, crosslinking reaction, etching reaction, structural change by surface chemical reaction, sterilization effect, wettability, adhesiveness, bondability, color compatibility, surface reinforcement, modification of surface heat resistance, sterilization, removal of harmful proteins/bacteria, etc.) according to plasma treatment, and a method using the plasma treatment apparatus.

Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.
