Choose the final abutments and fix them in the lab analogs (, 3. google_color_link = "cc6601"; Each screw access hole should be milled exactly with the trajectory of the supporting implant, as described in the following steps: One way to achieve a passive fit in the metal substructure is to make the substructure in multiple segments, connect these pieces in the patient’s mouth, and make an index of the whole piece. google_color_border = "FFFFFF"; Choose corresponding spark erosion implant abutment analogs with the patient’s implants. Spark erosion process: An overview Screw a guide sleeve over one of the terminal implants. Then the most distal retaining screw should be tightened and the rest of the retaining screw should be kept out. Rubeling G. Funkenerosion in der zahntechnik moglichkeiten und grezen. Author Jacob Jo Liju. The scope of this article is to discuss the mechanism of action of the process and its significance in implant dentistry along with critical evaluation of its merits and demerits. Implant body analogues are screwed into implant analogue sleeves and secured to the impressions [Figure 3] . After finishing the spark erosion process, if all of the retaining screws are tightened without milling the screw access holes, there will be a load concentration throughout the retaining screws (, 6. It is a chemical process that results in the loss of dental tissue. Shop Spark erosion process in dentistry An overview by Jacob Jo Liju. An ill-fitting substructure will cause excessive stress on the supporting implants, which eventually will cause crestal bone loss. It is rapid, efficient and accurate (within 0.0254 mm). If the assembly does not fit passively, cut the acrylic joints near the ill-fitting coping with a thin diamond disk to make sure all of the copings are fitting passively (. This procedure combines the functional and esthetic advantages of precision restorations with the advantageous properties of base metal alloys such as low thermal conductivity, high strength, and lower cost. Tighten all of the retaining screws before spark erosion and milling of the metal substructure (, 4. google_ad_format = "160x600_as"; 2nd ed. google_color_bg = "FFFFFF"; The shrinkage of the porcelain during firing introduces some stress to the metal substructure, which can ultimately cause an ill fit again. Int J Prosthodont 1992;5:114-21. Dental erosion, also called enamel erosion or tooth erosion, occurs when acidic substances wear away your enamel (tooth surface). In some fully implant-supported fixed denture designs, porcelain is applied to the metal substructure. The supra-structure has a perfect passive fit with no load concentration on the retaining screws (, 1. The dental spark erosion procedure offers a sophisticated method for using base metal alloys for these complex restorations. Frameworks with porcelain can be spark eroded without any stress on the porcelain due to the cooling action of the di-electric fluid.
