The present invention provides a surface treatment device of prosthetic teeth prosthesis for anodizing a surface to improve the functional and aesthetic functions of prosthetic teeth prosthesis for recovery of natural tooth loss. According to the present invention, a case is opened and closed at the front by a door and includes a treatment tank at the bottom thereof, in which an acid solution for anodizing is stored and a covered plate workbench is installed. In the workbench, a negative power terminal vertically penetrated and immersed in the acid solution of the treatment tank and a positive power are supplied to the top. At the bottom, the prosthesis, which is the object for anodizing, is detachably installed. Electrolytic anodic oxidation treatment of the prosthetic surface is performed by installing rod-shaped jigs with a gripping end vertically penetrating the workbench and submerged in the acid solution of the treatment tank. The negative power terminal is vertically penetrated in the center of the workbench to be submerged in the acid solution in the treatment tank. The workbench comprises a plate-shaped body having storage holes for arranging the jigs to the left and right sides, and a donut-shaped holder with receiving holes to allow the jigs to penetrate vertically. A common terminal is interposed between the body and the holder of the workbench, is supplied with a positive power from a single positive power terminal inserted through the holder from one side, and simultaneously supplies positive power to each of the jigs installed through the receiving holes provided in the holder of the workbench. Therefore, the present invention simplifies the structure of the treatment device and increases the work efficiency.COPYRIGHT KIPO 2020이러한 본 발명은 자연 치아 손실 또는 상실 부분의 회복 시술을 위한 인공치아 보철의 기능적ㆍ심미적기능 향상을 위하여 그 표면을 양극 산화 처리하는 인공치아 보철의 표면 처리장치를 제공함에 의해 달성되게 되는데, 이 표면 처리장치는 전면이 도어로 개폐되는 케이스 내부의 바닥에 양극 산화처리를 위한 산성용액이 저장되고 복개방식의 판형 작업대가 설치되는 처리 조를 가지며, 작업대에는 상하로 관통하여 처리 조의
