• Topical anesthesia will be administered using an infiltration technique.
• Atraumatic extraction will be done with the aid of periotome and Luxators.
• The extraction socket will be debrided to remove any residual debris or granulation tissue.
• Full-thickness midcrestal incision and vertical releasing incision on the distal side will be made, and a vertical releasing incision on the mesial side will be made if necessary. The extraction socket and the labial bone defect will be exposed by buccal and palatal flap reflection.
• Implant insertion will be performed according to the manufacturer's instruction, and then the implant will be inserted 2mm apical to the alveolar bone crest with adequate primary stability.
• The gap between the implant and the defect of the facial bone will be filled with the autogenous demineralized dentin graft to reach enough buccal bone supported and then will be covered with collagen membranes.
• Finally, the flap will be repositioned and sutured.

The pink esthetic score will be calculated on the parameters defined by (Fürhauser et al. 2005). Clinical photographs will be taken to evaluate peri-implant soft tissue through evaluating seven variables compared to a natural reference tooth including: mesial papilla, distal papilla, soft-tissue level, soft-tissue contour, alveolar process deficiency, soft-tissue color and texture. Using a 0-1-2 scoring system, 0 being the lowest, 2 being the highest value. The maximum achievable PES is 14.

Implant stability will be measured using Ostell which has a scale ranges from 1 to 100, the higher the ISQ the more stability

Gingival thickness will be evaluated 2 mm below the gingival margin with a short needle for and silicon disk stop. The needle will be inserted perpendicular to the mucosal surface, through the soft tissues with light pressure until a hard surface was reached. The silicone disc stop was then mounted in close contact with the gingival tissue surface. The insertion depth was assessed with a digital caliper accurate to the nearest 0.1 mm

It will be evaluated from the gingival margin to the mucogingival junction (MGJ). The MGJ was assessed with roll technique

Corono-apical distance between the peri-implant soft tissue margin and the cemento-enamel junction (CEJ) of the homologous contralateral tooth

Pain will be assessed post-surgically using the Visual Analogue Scale (VAS) with numbers from 0 to 10 score zero represented no pain while score 10 represented the worst pain imaginable

Three Yes or No Questions will be asked to the patient about his overall satisfaction about the procedure

Swelling will be assessed post-surgically using the Verbal Rating Scale (VRS) (García et al. 2008):

• Absent (no swelling),
• Slight (intraoral swelling at the operated area),
• Moderate (moderate intraoral swelling at the operated area) and
• Intense (intensive extraoral swelling extending beyond the operated area)
