•1. Adult patients (age above 20 years old) in need of a single tooth extraction in the maxillary incisor, canine, pre-molar area due to trauma, periodontitis, endodontic or unrestorable caries
•2. Full mouth plaque (FMPS) below 25% and bleeding scores (FMBS) below 10% at study baseline
•3. In case of active periodontal disease, the patient should have successfully completed periodontal treatment before enrolment
•4. Good soft tissues contours/profile after dental extraction and at least 2 mm of keratinised tissue.
•5. Adequate mesiodistal space for implant placement (=6.5 mm)
•6. Intact socket after dental extraction with a minimum of 5 mm in apical direction to ensure good primary stability for immediate DI
•7. Patient had adequate quantity of native bone to achieve a minimum primary stability. This was defined as a minimum insertion torque of 35 N/cm

•1. Presence of any chronic diseases or medication/ treatment known to affect oral conditions and bone turnover or contraindicate oral surgical treatment such as uncontrolled diabetes, head and neck radiation for cancer treatment or current treatment with bisphosphonates
•2. Physical or mental handicaps that would interfere with the ability to maintain adequate oral hygiene
