This randomized comparative clinical trial aims to evaluate the clinical, radiographic, and esthetic outcomes of flap versus flapless techniques for delayed dental implant placement in the maxillary esthetic zone. Twenty patients requiring implant placement in the maxillary anterior or premolar region will be randomly allocated into two equal groups. Group I will undergo implant placement using the conventional flap technique, while Group II will receive implant placement using the flapless technique. Clinical outcomes including postoperative pain, edema, surgical insertion time, and implant stability will be assessed. Radiographic evaluation will include peri-implant bone quantity, bone quality, and crestal bone loss. Follow-up examinations will be performed immediately after surgery and at 1, 3 and 6 months postoperatively.

Inclusion Criteria:

• Patients aged from 30 to 50 years old.
• Adults of both genders.
• Patients who are free from any systemic disease (ASA I).
• Patients with teeth loss at upper anterior and premolar regions more than 1-year.
• Presence of sufficient apical and peripheral bone to achieve primary implant stability (minimum 3-5 mm of bone beyond the socket apex and overall socket length ≥ 10 mm).
• Patients with bone quality classified as D3, as assessed by pre-operative CBCT.

Exclusion Criteria:

• Pregnant and lactating women.
• Heavy smoking (>10 cigarettes/day)
• Patients with bad oral habits such as bruxism.
• Patients with poor oral hygiene.
• Patients with gingival diseases.
• Patients with periodontal diseases (with severe vertical or horizontal bone loss).
• Teeth with periapical or lateral infection or lesions.
