Brief Summary

clinical trial The goal of this clinical trial is to record the esthetic outcome of the 3d printed hybrid resin crowns. It will also test which method of fabrication is advantageous than the other one. The main questions it aims to answer are: Does any of the fabrication methods differ in its esthetic outcome? Researcher will compare 3d printing fabrication to conventional fabrication method which is the milling technique to see if 3d printing of hybrid resin serves patients a better crown's esthetic outcome. Participants will: Receive a crown after implants are osseointegrated Visit the clinic once every 3 months for checkups and tests Keep records of level of patient's satisfaction.
