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.

The present invention relates to a collagen sponge-type composition for bone regeneration characterized in that the composition is manufactured by homogenizing a hydrated collagen; and a mixed solution of the lidocaine, epinephrine and thrombin, and then lyophilizing same. The composition according to the present invention, which activates undifferentiated cells in bone marrow and also activates bone regeneration capacity in bone marrow through the activation and differentiation of osteoclasts and osteoblasts, may be a method for successful treatment of medication-related osteonecrosis of the jaw (MRONJ) through a bone marrow activation treatment method, and may develop the treatment of the fundamental causes of MRONJ through a bone marrow activation treatment method using various growth factors for bone marrow activation and bone marrow activation factors such as cytokines and completely regenerate jaw bone conditions aesthetically and functionally. Accordingly, the composition according to the present invention may be useful in the treatment of various diseases caused by bone remodeling failure.

The present invention relates to a dental prosthesis molding block (10) for producing a dental prosthesis part. The block comprises an inner material (13) that is at least partially surrounded by an outer material (14), the hardness of which differs from the hardness of the inner material (13). The inner material (13) forms part of a first surface (11) of the dental prosthesis molding block (10). The invention further relates to a method for producing a dental prosthesis part. In said method, a dental prosthesis molding block (10) is provided, and the dental prosthesis part is produced by removing material from the dental prosthesis molding block (10) using a CAD/CAM process. In doing so, a pin having a self-tapping external screw thread is created.

The present invention discloses a method and a device or tooth pod for regeneration of teeth. In some exemplary embodiments, a method of implanting a tooth pod comprises of providing a tooth pod, implanting the tooth pod into an insertion point, and sealing the insertion point. The tooth pod comprises a composition of vitamin E oil and penicillin. In some exemplary embodiments, the tooth pod comprises of a permeable membrane defined by an outer layer and an inner layer, and a cavity defined by the space enclosed within the inner layer. In some exemplary embodiments, the device is a spherical pod. The tooth pod is implanted into the gum line at approximately ? the depth of a tooth, which provides space to growth of tooth upwards and downwards. The blood fills the hollow space of the tooth pod and forms nerve roots. Thereafter, a new adult tooth is formed.

Disclosed is a bone screw for 3D guided bone regeneration used in dental surgery for inducing and regenerating a part of alveolar bone defected in or around an implant surgery region. The bone screw includes: a head portion configured to provide a tenting function for a part of the alveolar bone to be regenerated or induced; a neck portion formed on a lower surface of the head portion; a screw portion formed beneath the neck portion and directly fixed to the alveolar bone in a thread fastening manner, wherein the alveolar bone can be induced or regenerated three-dimensionally. Since osteoinduction is promoted three-dimensionally to grow the alveolar bone rapidly by filling the bone graft, it is possible to shorten a period of the dental implant surgery procedure.

The present invention relates to a screw for a dental implant, comprising: a body (122) in which a through hole (124) is formed in the vertical direction; and a cover part (129) formed at an edge on a top end of the body (122), wherein the cover part (129) comprises: a protective body (120) formed by including a horizontal plate (127) formed to have a predetermined area in the horizontal direction and an inclined plate (128) formed downward at an end of the horizontal plate (127); and a connecting bolt (140) that fixes the protective body (120) to a fixture (200) by passing through the through hole (124) to be fastened to the fixture (200) implanted in the alveolar bone, and thus, when the protective body (120) is fixed to the fixture (200) by means of the connecting bolt (140) in the process of implant placement surgery, the cover part (129) covers and protects a bone graft material (320) implanted around the fixture (200), thereby assisting in regeneration of the alveolar bone.

The present invention relates to a dental prosthesis molding block for producing a dental prosthesis part.
