•1. Bilateral missing teeth in the maxillary anterior and premolar area
•2. Facial thin gingival phenotype facially (i.e. ?1.5 mm) as evaluated using cone-beam computed tomography (CBCT) (Claffey and Shanley 1986)
•3. Bilateral edentulous sites dimension of at least 5.5mm bucco-lingually, 5.5mm mesio-distally, and with a minimal bone height of 8 mm
•4. Teeth adjacent to the selected edentulous site must be free of periodontal disease involvement
•5. Adjacent teeth permit occlusal guidance
•6. An opposing dentition to the edentulous area with teeth, implants or fixed prosthesis

•1. Untreated rampant caries and/or uncontrolled periodontal disease
•2. Insufficient inter-occlusal distance for implant placement and restoration
•3. Smokers
•4. Systemic diseases contraindicating the dental implant placement like osteoporosis and uncontrolled diabetes mellitus
