Full mouth rehabilitation seeks to convert all unfavorable forces on teeth which invariably lead to periodontal conditions, into favorable forces which permit normal function and therefore induce healthy condition. Thus it entails the performance of all the procedures necessary to produce a healthy, esthetic, well-functioning, self-maintaining masticatory function. It implies the restoration of impaired occlusion, enhancement of esthetics, preservation of the remaining teeth and maintenance of a healthy periodontium. Treatment plan must result in healthy maintainability of the teeth and their respective supporting structures in harmony with the muscles, bones, joints and ligaments of the mouth and jaws.

This Book presents an innovative method for the electrical discharge drilling of micro holes. It makes use of tools insulated on the sidewall by means of a coating. The concept is to promote the process stability of micro EDM deep drilling by preventing secondary sparks. The performance of standard and customized tools is compared and reviewed against the main criteria of shape quality and tool wear. Process capabilities are also defined for a given coating. In micro electrical discharge machining (micro EDM), side-insulation of tool electrode can significantly improve the machining accuracy, especially for high aspect ratio structures. A new side-insulation approach micro single electrodes, in which spin-coating and room room curing are used to coat the micro tool electrodes with a very thin film of polymer, followed by an end-rubbing process to remove the insulation material from the electrode end surfaces.
