Uitkomstmaten
Primaire uitkomstmaten
Change in marginal peri-implant bone level 5 years after placing the definitive restoration.
Achtergrond van het onderzoek
• Background
There is a growing interest in restoring function in the posterior maxilla and mandible with dental implants. Next to this, these implants must be restored with crowns which are subject to minimal complications. Companies have introduced the option of screw-retaining and zirconia as crown material. The combination of posterior implants and screw-retained zirconia crowns are widely used, but prospective research on clinical performance and patient centered outcomes are scarce. Even more, 5-years data are lacking.
• Main research question
To evaluate the clinical performance of Nobel Biocare Implants restored with screw-retained zirconia crowns in the posterior maxilla and mandible. The primary objective of the study is marginal bone level changes by radiological assessments at 5-years follow-up. Secondary objectives are implant and restoration survival, condition of peri- implant mucosa and patients’ satisfaction.
• Design (including population, confounders/outcomes)
The study design is an observational study of a group of patients which were treated 5 years ago with a dental implant and a screw-retained implant-supported zirconia restoration because of a missing tooth in the posterior region. Outcomes: primary outcome is the change in marginal peri-implant bone level 5 years after placing the definitive restoration. Secondary outcome measures will be implant and restoration survival, peri-implant mucosa health and patients’ satisfaction using a questionnaire.
Doel van het onderzoek
Stable peri-implant bone levels, high implant and restoration survival rate and satisfied patients.

Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
• 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 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.
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
• Medical and general contraindications for the surgical procedures;
• Presence of an active and uncontrolled periodontal disease;
• Bruxism;
