This project consists of placing dental implants at extraction sites. Bone drilling and implant placement are performed using the flapless method with the use of a surgical guide allowing guided surgery. After implant placement, temporary teeth are immediately made and placed on the implants to guide the gingival contour.

Bone and soft tissue retraction at the implanted sites are measured radiographically and digitally using surface scan superimposition over a 12-month period.

Inclusion Criteria:

• Absence of systemic or osseous disease that may impair peri-implant healing
• Age ≥ 21 years
• Acceptable oral hygiene
• Presence of both adjacent teeth
• Absence of acute infection in the treated area
• Absence of periodontal pockets > 3mm at the concerned site
• Absence of pre-operative defect at the buccal bone wall (dehiscence or fenestration)
• Per-operative integrity of the osseous and gingival structures (during tooth extraction)
• Light or non-smoker (<10 cigarettes per day)

Exclusion Criteria:

• Myocardial infarction within the past 6 months.
• Poorly controlled diabetes (HBA1c > 7.5%).
• Coagulation disorders.
• Radiotherapy to the head/neck area within the past two years.
• Present or past treatment with intravenous bisphosphonates.
• Immunocompromised patients.
• Psychological or psychiatric problems.
• Alcohol or drug abuse.
• Poor oral hygiene and motivation (full mouth plaque score > 30% and/or full mouth bleeding score > 20%).
• Uncontrolled periodontal disease.
