- No soft tissue augmentation performed at the site prior to surgery;
- Overall health is good, with no systemic diseases that may affect bone metabolism or wound healing;
- Good periodontal condition, no progressive alveolar bone resorption, no periodontal abscess;
- Smoking ≤ 10 cigarettes per day.
