CONNECTION DEVICE OF DENTAL STRUCTURE

摘要

The present invention relates to a dental structure connecting device and, more specifically, to a dental structure connecting device including: an abutment which includes a lower side part inserted into an alveolar bone or a fixture and a protrusion part protruding from the alveolar bone or the fixture to the upper side so that the fixture is implanted into the alveolar bone with the abutment in one united body or the fixture implanted in the alveolar bone fixes the position of the abutment; a fixed cap which has an outer circumference surface combined with a dental structure and includes a first upper end part and a first lateral part which is extended to the lower side by being bent from the edge of the first upper end part in order to have an accommodation space which is larger than a protrusion part inside; and an elastic medium means which is combined with the protrusion part in order to be attachable and detachable while accommodating at least one part of the protrusion part inside and includes a second upper end part facing the first upper end part and a second lateral part facing the first lateral part in order to be combined with the fixed cap to be attachable and detachable while the outer circumference surface is accommodated in the accommodation space of the fixed cap. The dental structure connecting device has a first buffer space which is arranged between the first lateral part and the second lateral part in order to be able to buffer external force in order to directly deliver the external force to the abutment when the external force is added to the first lateral part from the outside.
