Recruitment & Eligibility

• Status: Completed
• Sex: All
• Target Recruitment: 45

Inclusion Criteria

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

Exclusion Criteria

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
3. Alcoholism or chronic drug abuse
4. Presence of clinically symptomatic periapical radiolucencies, acute abscesses or chronic sinus tracts at the site of extraction
5. Smoking
6. Absence of one of the neighbouring teeth

Primary Outcome Measures

Name	Time	Method
The aesthetic of gums around false teeth measured using the Pink Aesthetic Score index at 12 months from the time the treatment is completed

Secondary Outcome Measures

Name	Time	Method
<br> 1. Radiographic bone loss measured from the mesial and distal aspect of the implant shoulder to the first bone-to-implant contact at 12 months post-loading<br> 2. Periodontal measurements including probing pocket depth, papilla height, gingival margin position, width of keratinised tissue, plaque index and bleeding index, taken on the day of the crown fit (T0) and at 12 months post-loading (T12)<br> 3. The aesthetic of implant-supported false teeth measured using the White Aesthetic score (WES) at 12 months from the time the treatment is completed<br> 4. Patients' reported outcomes measured using a visual analogue scale at 1-year post-loading<br>
