Full-zirconia implant-supported restorations with angulated screw channel abutments in the posterior region; a 5-years prospective case series study

•Patients referred to the department of Oral and Maxillofacial Surgery 5 years ago and treated with a dental implant and a screw-retained implant-supported zirconia restoration because of having a missing tooth in the posterior region. At the time of treatment:
•The patient was 18 years or older;
•The missing tooth was a premolar or molar in maxilla or mandible;
•Sufficient healthy and vital bone to insert a dental implant with a minimum length of 8 mm and at least 4.0 mm in diameter with initial stability > 45 Ncm
•The implant site was free from infection;
•Adequate oral hygiene (modified plaque index and modified sulcus bleeding index = 1);
•Sufficient mesio-distal, bucco-lingual, and interocclusal space for placement of an anatomic restoration;
•The patient was capable of understanding and giving informed consent.
