入选标准
- •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.
排除标准
- •Medical and general contraindications for the surgical procedures;
- •Presence of an active and uncontrolled periodontal disease;
- •A history of local radiotherapy to the head and neck region.
