The purpose

To assess and compare the esthetic outcome and clinical performance of anterior maxillary all ceramic implant single crowns based either on prefabricated zirconia abutment veneered with pressed ceramics or on a CAD/CAM (computer-aided design and computer-aided manufacturing) CARES® abutment veneered with hand build-up technique. Participants will be recruited from the patient population who has previously received dental implant treatment, received a provisional restoration and met the inclusion and exclusion criteria according to the study protocol. After final impression, patients will be randomised into Group A (prefabricated anatomic abutments ): one-piece screw retained single crown using a press technique (fluorapatite glass-ceramic, e.max ZirPress) with cut-back technique or Group B (CAD/CAM CARES® abutments): one- piece screw retained single crown with a hand build-up technique (fluorapatite veneering ceramic, e.max Ceram). One week after final restoration (base line visit) the primary and secondary outcome parameters will be assessed. The patients will be followed up to 5 years after final restoration.
