Abstract
Provided are a method of manufacturing a fixture of a dental implant with an improved structure in which the performance of osseointegration is excellent, spread of inflammation is reduced and a combination force between the fixture and an alveolar bone is remarkably increased, and a fixture of a dental implant manufactured by the method. The performance of osseointegration is excellent, and spread of inflammation can be reduced, and a combination between the fixture and an alveolar bone can be remarkably improved. Furthermore, the fixture of the dental implant having the above structure can be easily manufactured.
Claims10
A method of manufacturing a fixture of a dental implant, the method comprising:
- providing a polished surface of a screw portion by cutting the screw portion comprising forming a lower screw portion formed as a single-thread screw at a lower side of the fixture of the dental implant and forming an upper screw portion formed as a double-thread screw at an upper side of the fixture;
- forming a fixed groove in the upper screw portion of the fixture wherein the fixed groove surrounds the upper screw portion in a circumferential direction;
- inserting a ring-shaped protection jig in the fixed groove of the upper screw portion and fixing the protection jig to the fixed groove to surround a polished waist portion of the upper screw portion in a circumferential direction,
- wherein the protection jig is composed of a synthetic resin having elasticity, and
- wherein the protection jig comprises a body portion having a combination hole configured to be inserted and fixed in the upper screw portion of the fixture and a fixed protrusion is formed in an internal side of the combination hole which is configured to be engaged in the fixed groove of the upper screw portion and fixed therein;
- performing surface processing on the polished screw portion excluding the polished waist portion of the fixture which remains polished and surrounded by the protection jig, using sandblasting;
- and
- removing the protection jig fixed on the waist portion of the fixture thereby leaving exposed the polished waist portion.
