Abstract

Accuracy is the most important thing in implant prosthesis, for this reason it is essential procedure to check the accuracy of impression taking. However, impression material has its own error and the error occurs in model-making procedure. As an alternative way to this, using intraoral scanner can be suggested and many studies were issued reporting that there's no statistically significant difference in accuracy between intraoral scanner and conventional impression. Therefore, the purpose of this study is to report the process of making of implant prosthesis using intraoral scanner, which is more convenient, fast, accurate compared with conventional method.
