The present invention relates to a cover-type implant assembly including: an alveolar bone cover coupled to cover a predetermined area of an outer surface of an alveolar bone directed toward an oral cavity a cover coupling shaft formed to extend toward the oral cavity from a surface of the alveolar bone cover and removably coupled with the alveolar bone cover a fixing member coupling the alveolar bone cover and the alveolar bone with each other an abutment inserted into and fixed to an inside of the cover coupling shaft and a dental prosthetic appliance coupled with an end portion of the abutment. The alveolar bone cover is provided such that a predetermined margin gap is formed so that a bone graft material can be filled between the alveolar bone and the alveolar bone cover and in a semicircular form covering the outer surface directed toward the oral cavity in a cross sectional shape of the alveolar bone, the alveolar bone cover is provided such that its diameter varies in a length direction such that an uneven shape is present that corresponds to the shape of an outer peripheral surface of the alveolar bone, the alveolar bone cover is formed to have the form of a mesh net having in its surface a plurality of coupling through-holes, an inside surface of the alveolar bone cover is treated to be rugged so that synostosis can be promoted, the fixing member can be separated from the coupling hole after the bone graft material is fixed after the fixing member is inserted into the alveolar bone cover through the coupling hole, and the alveolar bone cover is formed by the use of a 3D printer.COPYRIGHT KIPO 2017본 발명은 덮개형 임플란트 조립체에 관한 것으로서, 구강을 향하는 치조골의 외면을 일정면적 덮도록 결합되는 치조골덮개와 상기 치조골덮개의 표면으로부터 구강을 향해 연장형성되며, 상기 치조골덮개에 착탈가능하게 결합되는 덮개 결합축과 상기 치조골덮개와 상기 치조골을 결합시키는 고정부재와 상기 덮개 결합축의 내부에 삽입 고정되는 어버트먼트와 상기 어버트먼트의 단부에 결합되는 치아보철물을 포함하며, 상기 치조골덮개는 상기 치조골의 단면형상에서 상기 구강을 향하는 외면을 덮는 반원 형태로 상기 치조골과의 사이에 골이식재를 충진할 수 있도록 일정 여유간격이 형성되도록 구비되고, 상기 치조골덮개는 상기 치조골의 외주면 형상에 대응되는 요철형상이 있도록 길이방향을
