Abstract
:1. Introduction
2. Materials and Methods
2.1. Study Setting and Patient Selection
2.2. Inclusion Criteria
- -
- 18–75 years of age;
- -
- Presence of a single hopeless tooth which required extraction;
- -
- Possibility to be included in a hygiene recall program at 1, 3 and 12 months;
- -
- The site should allow the placement of an implant at least 10.00 mm in length;
- -
- And 3.8 mm in diameter.
2.3. Exclusion Criteria
- -
- Medical and/or general contraindications for the surgical procedures (ASA score ≥ 3);
- -
- Systemic diseases such as uncontrolled diabetes mellitus;
- -
- Pregnancy;
- -
- Poor oral hygiene and lack of motivation;
- -
- Active clinical periodontal disease in the natural dentition expressed by probing pocket depth >4 mm and bleeding on probing;
- -
- Smoking;
- -
- Malocclusion (i.e., closed bite or open bite);
- -
- Bisphosphonate and/or antidepressant therapy.
2.4. Sample Size
2.5. Patients Allocation and Pre-Surgical Protocol
2.6. Implant Surgery
- -
- Early implant group (Type 2 for ITI): the implant was placed 8–12 weeks after extraction. In this case, the hopeless tooth was previously removed because affected by acute periapical lesion with endodontic abscess. These teeth presented fistula, tenderness and swelling before extraction. In some cases, antibiotic therapy was scheduled 3–7 days before extraction.
- -
- Delayed implant group (Type 4 for ITI): the implant was placed in the edentulous area where cortical bone was evident on the radiograph. Tooth extraction, for any reason, was performed 10–12 months before.
2.7. Resin-Bonded Prosthesis (RBP) Positioning
2.8. Follow-Up
2.9. Radiographic Evaluation
- -
- Mesial and Distal Marginal Bone Levels (MBL-M and MBL-D)
- -
- Mesial and Distal Cement–Enamel Junction (CEJ-M and CEJ-D)
- -
- Mesial and Distal Bone Level Area (Area-M and Area-D)
