1. Gu Jun with 2. Yuan-Fei Fu 2. Xu Bing Kan (1. Shanghai Jiaotong University Affiliated Ninth People's Hospital Dental Technology Center, Shanghai 2000112. Shanghai Jiaotong University Affiliated Ninth People's Hospital, Department of Prosthodontics) Abstract AGC plating techniques (often referred to as gold deposition) for the first time since 1986, has successfully used in dental field, has been tried and tested as a promising technique and has widely used in the dental field . This article details the technical room AGC Plating operation principle, characteristics, operation, and operation of the attention, and operation and handling of common reasons for failure to make an analysis. For the better development of this technology to provide reference. Key words electroplating precious metals brightening agents shaped retainer ring AGC plating technology also known as wet-cast (Gold and silverRefin. Ery), it works by [Au (S03) 2]. _ + E 11 Au +2 SO3. Electrolyte, the major components of gold ions, conductive salt component, PH value of buffer / stabilizer, specialized chemical electrolyte stabilizer and brightening agents. Brightening agent's role is brightening, even, to make the surface shiny crown. Plating the first time in Australia in 1961 used inlay. 1986, developed the first electroplating apparatus Gammat models. 1997 model years, AGC-Miero 5h plating six crown may have been greatly accelerate the speed of electroplating operations. To 1998 AGC-MieroPlus model, an electroplating process can be completed in 16 restorations. Greatly reduce the operational processes, has been able to fully meet the market requirements. 1 advantages of electroplating technology 1.1 Good marginal seal Plating using plating technology produced porcelain crowns, porcelain crowns before and after sintering fused gap size of 19 ~ 60txm, available clinical effects of long-lasting repair. While using the traditional casting process there are often produced restoration problem of poor marginal adaptation, marginal gap generally 50 ~ 200 ~ m. 1.2 Protection of the pulp Plating thickness crown generally 0.2mm (Figure 1), and the traditional PFM compared to a decrease of amount of tooth preparation. Expanded the scope of repair. 1.3 good biocompatibility Due to inertia and a gold electrochemical corrosion resistance. So that organizations without any allergic reaction. 1.4 long service life with high aesthetic effect. Its natural warm gold, porcelain ceramic powder from the inside, revealed after the warm yellow, to avoid the use of non-precious metal alloys or ceramic cement gum discoloration after. 1.5 success rate Long-term clinical trials showed that the success rate of more than 96%. The technology eliminates the use of the casting process, avoiding the pores in the casting process, impurities such as uneven and frequently asked questions. Precious metal plating compressive strength 120N. Structure under the microscope showed uniform and compact; casting precious metal compressive strength of 30N, and the microscopic structural disorder. Shape of ceramic powder. So is the casting precious metal electroplating precious metals intensity of 4 times to achieve complete oral rehabilitation requirements. Clinicians in dental health status (if there is inflammation of the teeth, gingivitis, root tips go far, should make anti-inflammatory or root canal treatment for tooth preparation after the RAN), the requirements for the Preparation of the teeth: buccal lip side of the worn out 1.2mm, cut-side grinding than 1.8 ~ 2mm, neck edge with concave arc-shaped shoulder, smooth surface without damage. Inlay teeth were ground equipment volume 2mm, and the prepared occlusal surface retention of the central box-shaped part of the side worn out 1.8mm, reaching 6 degree angle hole (Figure 2).
