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.COPYRIGHT KIPO 2014본 발명은 치과용 구조물 연결장치에 대한 것으로서, 더욱 상세하게는 픽스츄어가 상기 어버트먼트와 일체형으로 존재하여 치조골에 식립되거나, 치조골에 식립된 픽스쳐에 의하여 위치고정될 수 있는 어버트먼트로서, 치조골 또는 픽스쳐 내에 삽입되는 하측부와, 상기 치조골 또는 픽스쳐로부터 상측으로 돌출되는 돌출부를 포함하는 어버트먼트 외주면이 치과용 구조물에 결합되어 있으며, 내부에 돌출부보다 큰 수용공간이 마련되어 있는 고정캡으로서, 제1상단부와, 상기 제1상단부의 가장자리로부터 절곡되어 하측으로 연장되는 제1측부를 포함하는 고정캡 및 상기 돌출부의 적어도 일부분을 내부에 수용하면서 상기 돌출부에 착탈가능하게 결합되고, 외주면은 상기
