Abstract:
The present invention relates to a superhydrophilic coating method for an implant having a rough surface made of titanium or titanium alloy material, which maintains a wet or dry condition at room temperature to preserve a superhydrophilic property of an implant surface from which contaminants are removed, wherein the invention can exhibit high biocompatibility and excellent body fluid and blood compatibility after implant surgery by a superhydrophilic coating layer which is uniformly formed on the implant surface. Consequently, the implant of the invention has an exceptional osteogenesis effect and an excellent effect of reducing an osseointegration period.
Abstract:
The present invention relates to a dental implant assembly having a settlement-preventing step so as to prevent an abutment from settling due to a vertical load caused by mastication after the dental implant assembly is implanted. The present invention provides a dental implant assembly, which is implanted in an oral cavity to replace a lost tooth and includes a fixture implanted in an alveolar bone, an abutment coupled with the fixture to locate a dental prosthesis on the fixture, and a settlement-preventing means for preventing settlement of the abutment by being in contact with the fixture when the abutment is coupled with the fixture.
Abstract:
The present invention relates to a dental drill for quickly and safely lifting the sinus without damaging the mucous membrane therein when operating the sinus. The dental drill, according to the present invention, comprises a connection portion which is formed on the upper end of a body so as to be connected to a driving device, and a cutting portion, which is formed at the lower end of the body, having cutting blades for drilling, wherein the cutting portion comprises a plurality of cutting blades which are arranged in a circle so as to have a cylindrical shape with an empty hollow inside to allow collection of a main disk, and wherein the cutting blades are provided with an curved surface end at the end, which is rounded, so that damage to the mucous membrane can be prevented even when the outer circumferential edge of the end of the cutting portion comes into direct contact with the mucous membrane when drilling.

Abstract:
The present invention relates to a dental implant abutment and to a method for manufacturing same, and more particularly, to a dental implant abutment which supports a porcelain prosthesis so as to define the outer appearance of an artificial tooth, and which his fixedly coupled to a fixture, and to a method for manufacturing same. The dental implant abutment includes: a first part having a coupling structure corresponding to the inner structure of a fixture such that the first part is coupled to the fixture; a second part extending upward from the first part so as to contact the gums; and a third part extending upward from the second part, the outer circumferential surface of the third part including side and top surfaces, wherein porcelain is attached to the outer circumferential surface of the third part, a concave portion that is inwardly recessed is defined in the top surface, and the third part has a horizontal cross-sectional area that gradually increases as it progresses upward from the concave portion.
Abstract:
The present disclosure relates to a method for making an implant abutment, comprising: a first step of obtaining information through a scan on an oral region in which an implant fixture is to be installed, and forming a virtual model corresponding to the shape of the oral region; and a second step of building an implant abutment over the virtual model.
Abstract:
The present invention relates to a high energy ray irradiation apparatus for a dental implant. More particularly, the present invention relates to a high energy ray irradiation apparatus for irradiating a high energy ray to a dental implant, the apparatus comprising: a housing having a processing space therein for high energy ray irradiation; a lamp unit which is arranged within the processing space and which irradiates a high energy ray to a dental implant to reform or clean the surface of the dental implant; and rotating means for rotating the dental implant disposed within the processing space such that a high energy ray can be irradiated all over the surface of the dental implant.
Abstract:
The present invention relates to a surgical instrument for collecting autologous bone. The surgical instrument for collecting autologous bone comprises: a handle portion connected to a driving device; and a cutting portion which collects bone pieces of a person to be surgically operated on while rotating, wherein the cross-sectional area of the cutting portion is 10-40 % of the area of an imaginary circle having a diameter which is the distance from the center thereof to the outermost portion.
Abstract:
The present invention relates to a membrane for alveolar bone regeneration, and more specifically, to a membrane for alveolar bone regeneration which guides bone regeneration by covering an implant filling a bone defect region, comprising: a coupling portion which comprises a central hole for allowing an insertion body for an implant to be inserted into alveolar bone to penetrate through, and is coupled to the insertion body for an implant; a lateral bent portion which is bent downward from the coupling portion and as a whole forms a curved shape; and lateral cover portions which are protruded from both edges of the lateral bent portion and are bent toward the defect region of alveolar bone, wherein the lateral bent portion and the lateral cover portions are three-dimensionally formed in advance so as to fit the final shape of the alveolar bone to be regenerated.
Abstract:
An implant fixture that is inserted into a bone tissue formed of a cortical bone and a cancellous bone while rotating on a central axis to thereby form an artificial tooth root, the implant fixture including a first portion that is inserted into the cortical bone and includes a first screw thread having first peaks and first roots alternating with one another on an outer surface of the first portion; and a second portion that is disposed below the first portion and inserted into the cancellous bone.
