Abstract: Disclosed is a head mounted display device. The head mounted display device includes a head mount unit wearable on a head of a user, a display unit supported on the head mount unit and sending an image to eyes of the user, and a position adjustment unit coupled to the head mount unit, connected to the display unit, and moving the display unit relative to the head mount unit such that a position of the display unit varies with respect to the eyes of the user.

Abstract: Provided is a dental implant fixture. The dental implant fixture includes: a body portion having an outer wall on which a threaded portion to be placed in an alveolar bone is formed; an abutment contact and support portion formed on an inner wall of the body portion at an entrance side, to which an abutment is coupled and supported in contact therewith; and an internal connection part formed on the inner wall of the body portion in an area where the abutment contact and support portion ends in a direction in which the body portion is placed in the alveolar bone, and having a non-circular cross-sectional structure to allow a predetermined tool for rotational handling of the body portion to be optionally connected thereto.

Abstract: A dental flattening drill is disclosed, which can include a drill lance having a drill blade for forming an implant groove and a drill housing to which the drill lance is detachably coupled. The drill housing includes a processing blade for flattening the alveolar bone region around the implant groove.

Abstract: A dental flattening drill is disclosed. According to one embodiment of the present invention, a dental flattening drill comprises: a drill lance having a drill blade for forming an implant groove by drilling, down till a predetermine depth, an implant location of an alveolar bone in which a fixture is to be implanted; and a drill housing to which the drill lance is detachably coupled, and having a processing blade for flattening the alveolar bone region around the implant groove.

Abstract: Disclosed herein is an apparatus for coating a substrate, including a horizontal coating unit having an inlet and an outlet through which a substrate is moving in and out horizontally, and coating surfaces of the substrate with coating liquid by horizontal dipping method to form a protective layer; and a squeegee unit arranged outside the outlet of the horizontal coating unit and being in close contact with the protective layer of the substrate moving out of the horizontal coating unit through the outlet to uniformize coating thickness of the protective layer. According to the present invention, coating thickness of a protective layer coated on a substrate is formed uniformly, and in particular coating quality of edges of the substrate is improved. Therefore, it is possible to minimize foreign substances introduced during manufacturing process of the substrate, thereby reducing defective rate due to foreign substances and improving productivity.

Abstract: A surface treatment device of dental implant according to an embodiment of the present invention includes: a body providing a treatment chamber to receive a surface processing object; a cover combined to the body to selectively open the treatment chamber; a light source irradiating UV light to a surface of the surface treatment object; and a reflective plate positioned at a bottom of the treatment chamber to reflect the UV light emitting from the light source toward the surface treatment object.

Abstract: Provided is a bone filling complex and method of preparing the same. The bone filling complex includes a matrix including a hydrogel-type hyaluronic acid derivative; and a bone derivative filling the matrix For example, the bone filling complex can be used to regenerate an injured alveolar bone.

Abstract: Provided is a bone filling complex and a method of preparing the same. The bone filling complex includes a matrix including a hydrogel-type hyaluronic acid derivative; and a bone derivative filling the matrix, and thus adhesion can be prevented and excellent bone generation property can be obtained. For example, the bone filling complex can be used to an injured portion of alveolar bone to derive an regeneration of the alveolar bone.

Abstract: Provided are a bone filler for orthopedic and dental applications and a method of fabricating the same. The bone filler includes a pillar-like body having at least one through hole. In addition, the method of fabricating a bone filler includes preparing a slurry including a bioactive material, pressing the slurry to form a pillar-like body including at least one through hole, and calcining the body.
