The objective of this study will be to assess the efficacy of the peri-implant mucosal thickness enhancement following either subepithelial connective tissue grafts or Amnion Chorion Membrane placed simultaneously with dental implant placement.

• Ability to maintain good oral hygiene as evidenced in recall visits.
• Aged 30 to 55 years.
• Stable periodontal condition and missing one single tooth (maxillary anterior teeth and premolars) with adjacent teeth present and thin mucosal phenotype (< 2mm bucco- lingual thickness).

Exclusion Criteria:

• Medically compromised patients and systemic conditions precluding periodontal surgery.
• Smokers.
• Severe hematologic disorders (e.g., hemophilia or leukemia), uncontrolled infectious or metabolic diseases that could compromise normal healing, liver, or kidney dysfunction/failure.
• Patients subjected to irradiation in the head and neck area.
• Patients treated or under treatment with intravenous amino bisphosphonates.
