Aandoening
The study design is an observational study of a group of 120 patients who were treated 5 years ago with immediate dental implant placement and an implant-supported restoration because of having a failing tooth in the maxillary aesthetic region or, in case of a post-extraction defect, were treated with an alveolar ridge preservation, delayed implant placement and an implant-supported restoration.

Primaire uitkomstmaten
Change in peri-implant marginal bone level.
Achtergrond van het onderzoek
• Background
There is a growing tendency to place single tooth dental implants in the aesthetic zone immediately after extracting a failing tooth, preferably combined with immediate provisionalization. If a post-extraction site has a bone defect, so not full-filling the requirements for immediate implant placement, an alveolar ridge preservation is mandatory. Full-scale evaluation of immediate implant placement and implant placement after alveolar ridge preservation with a follow-up of at least 5 years is underreported in this field of implant dentistry.
• Main research question
The aim of this 5-years observational study was to analyze peri-implant bone changes, mucosa levels, effect of type of soft tissue augmentation technique, aesthetic ratings and patient-reported satisfaction with the maxillary aesthetic region following immediate implant placement and implant placement after alveolar ridge preservation.
• Design (including population, confounders/outcomes)
The study design is an observational study of a group of patients which were treated 5 years ago with immediate dental implant placement and an implant-supported restoration because of having a failing tooth in the maxillary aesthetic region. In case of a post-extraction defect, patients were treated with an alveolar ridge preservation, delayed implant placement and an implant-supported restoration. 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 and changes in interproximal peri-implant mucosa, midfacial peri-implant mucosal level , effect of soft tissue augmentation technique, aesthetic outcome assessed by means of an objective index and patients’ satisfaction using a questionnaire.
Doel van het onderzoek
Stable peri-implant bone levels, stable peri-implant soft tissue 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 immediate dental implant placement and an implant-supported restoration because of having a failing tooth in the maxillary aesthetic region or, in case of a post-extraction defect, were treated with an alveolar ridge preservation, delayed implant placement and an implant-supported restoration. At the time of treatment:
• The patient was 18 years or older;
• The failing tooth was an incisor (central or lateral), cuspid or first bicuspid in the maxilla; the adjacent teeth are natural teeth;
• Sufficient healthy and vital bone to insert a dental implant with a minimum length of 10 mm and at least 3.5 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 temporary restoration could be designed free from occlusal contact;
• 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;
• Smoking
• A history of local radiotherapy to the head and neck region.
