- Background Adaptation of a dental implant and its restoration to the existing anatomy in the region of a missing tooth is presumed to be a reliable procedure. During the follow-up it appears that peri-implant bone level is stable, peri-implant soft tissues are healthy and patients are satisfied with the result. However, the number of 10-years studies on implants in the posterior region of maxilla and mandible is limited and much more studies with longer follow-up periods are needed to confirm the positive outcomes. - Main research question The primary objective of the study is marginal bone level changes by radiological assessments at 10-years follow-up. Secondary objectives are implant and restoration survival, condition of peri- implant mucosa and patients' satisfaction. - Design The study design is an observational study of a group of patients which were treated 10 years ago with a dental implant and an implant-supported restoration because of a missing tooth in the posterior region. Outcomes: primary outcome is the change in marginal peri-implant bone level 10 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. - Expected results Stable peri-implant bone levels, stable peri-implant soft tissue levels, high implant and restoration survival rate and satisfied patients.

Eligibility | Inclusion Criteria before treatment: - Patients referred to the department of Oral and Maxillofacial Surgery 10 years ago and treated with a dental implant and an implant-supported 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 8.5 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. Exclusion Criteria at time of treatment: - Medical and general contraindications for the surgical procedures; - Presence of an active and uncontrolled periodontal disease; - Bruxism; - Smoking - A history of local radiotherapy to the head and neck region. |
