Introduction. For centuries, the literature and art have indicated that the smile represents a key role in facial aesthetics and thus in the integration into society of the individual. The technological progress has made modern dentistry to seek less invasive methods to restore masticatory apparatus functions. For modern dentist, the challenge is to conciliate the aesthetic and functional objectives, trying to get the best result. Thanks to a variety of options for dental restoration , we have many choices for repairing, worn, decayed, demaged or missing teeth restoring a healthy and beautiful smile.  Aim of the study. The silicone guide with wax up technique allows the placement of direct composite on the palatal surfaces of upper anterior teeth in an efficient and accurate manner. We planned to realize a smile analysis and method of frontal teeth restoring, exploring techniques of manufacturing silicone template and to achieve esthetic and long- term results.   Materials and methods. The study was performed on a group of 12 patients (5 female and 7 male), aged between 24-27, showing aesthetic impairment. Of the 12 cases, 8 were diagnosed with non-caries lesion on anterior teeth and 4 cases with caries lesion. 8 were treated by simple preparation for better retention and 4 were treated by preparation and removing of necrotic dentin in the tooth cavity. The silicone key was made according to the wax up.  Results. The results of the aesthetic analysis were collected from the level of face, lips, dental arches and occlusal level. Conclusions. Restoration using the Silicone Guide technique and wax technique are combined to give an aesthetically conservative and beautiful result, benefiting from a considerable saving in time and cost.
