RESUMEN
The development of ceramic systems amplified the number of alternatives to modern restorative dentistry in an attempt to replace the infrastructure of metal dentures; high-performance ceramics have been improved and increasingly used in dentistry in search of an aesthetic improvement. Among the dental ceramic, zirconia has emerged as a promising and versatile material, due to their biological properties, mechanical and optical, which certainly has accelerated the routine use of CAD-CAM crowns, bridges, abutments and prostheses on implants, technicians and dentists. The ceramic restoration fine adjustment of System Precision Prosthetic Connection focus on cutting-edge technology bringing a level of precision in aesthetic problems in combination with modern materials that offer improved biocompatibility and aesthetic restoring the natural smile. Thus, the Precision System Connection was chosen for the clinical case presented in order to associate its qualities with a biomechanical greater aesthetic refinement
