Primary | Pink esthetic score (PES) | The PES is based on seven variables: mesial papilla, distal papilla, soft-tissue level, soft tissue contour, alveolar process deficiency, soft-tissue color and texture. Each variable will be assessed with a 2-1-0 score, with 2 being the best and 0 being the poorest score. | 3 months | |

Primary | White esthetic score (WES) | The WES is based on five variables of the clinical crown: general tooth form; outline and volume, color, surface texture, translucency and characterization. Each variable will be assessed with a 2-1-0 score, with 2 being the best and 0 being the poorest score. | 6 months | |

Primary | Peri-implant Probing Depth (PD) | Peri-implant probing depth refers to the distance from the gingival margin to the bottom of the sulcus depth. The peri-implant sulcus depth will be measured using a graduated plastic autoclavable periodontal probe. In addition to the aforementioned intervals, it will be measured at the day of final restoration placement. The probe will be held parallel to the long axis of the implant and introduced with light force to the peri-implants sulcus.Measurements will be made at 6 sites around each implant; mesio-buccal, mid-buccal, disto-buccal, mesio-palatal, mid-palatal and disto-palatal. Probing depth of 1 mm or less will be recorded as 1 mm, and those exceeding 1 mm, but less than 2 mm, will be recorded as 2 mm, and so on. | 3 months | |

Primary | Modified Sulcus Bleeding Index (BI) | A score of 0-3 will be assigned to each labial and palatal surface of the implant then the average for each implant will be calculated according to the following criteria:
Score 0: No bleeding when a periodontal probe is passed along the gingival margin adjacent to the implant. Score 1: Isolated bleeding spots visible. Score 2: Blood forms a confluent red line on margin. Score 3: Heavy or profuse bleeding. |

Primary | Modified Plaque Index (PI) | The presence or absence of plaque around abutments will be scored at four sites of each implant; buccal, lingual, mesial and distal then the mean will be calculated. This will be carried-out by visual inspection with the aid of a mouth mirror and a plastic periodontal probe after air drying of the abutments. The criteria for assessment include:
Score 0: No plaque in the gingival area, tested by running the side of plastic probe along the abutment surface at the entrance to the peri-implant sulcus. Score 1: Presence of a film of plaque near the gingival margin recognized by running the plastic periodontal probe along the abutment surface. Score 2: Moderate accumulation of plaque near or within the peri-implant sulcus, which could be seen naked eye. Score 3: Abundant plaque or soft matter within the peri-implant sulcus and or the mucosal sulcus margin and adjacent implant surface. |

Primary | Radiographic evaluation of alveolar bone using cone beat computed tomography (CBCT) | The level of alveolar bone around each implant will be assessed using CBCT. The vertical bone change (distance from the implant platform to the first bone-to-implant contact, in mm) around each implant will be assessed at the buccal, lingual, mesial and distal aspects then the mean will be calculated. | 3 months | |
