Inclusion criteria

Inclusion criteria: 1) Over 18 years of age 2) Need for an implant-supported crown to replace a maxillary tooth at the location of an incisor, cupsid or first/second bicuspid 3) Single tooth diastema as a maximum 4) Presence of a small bone deficiency of less than 4 mm 5) Sufficient occlusal and mesio-distal dimensions for insertion of one implant with a functional prosthetic restoration.

Exclusion criteria

Exclusion criteria: 1) Presence of clinical active periodontal disease. 2) Presence of an acute inflammatory oral disease. 3) Smoking. 4) Diabetes. 5) A history of radiotherapy in the head-and-neck region or current chemotherapy 6) Disability (mental and/or physical) to maintain basic oral hygiene procedures. 7) Under eighteen years of age

Design outcomes

Primary

Measure	Time frame
level of the marginal bone around the implant	—

Secondary

Measure	Time frame
1.the plaque index (PI), 2.the bleeding index BI, 3.the gingiva index (GI), 4.the pocket probing depth (PPD), and 5.the width of the attached mucosa (WAM) 6. Peri-implant esthetic score (PES) reflects the following five items: mesial papilla, distal papilla, curvature of the facial mucosa, level of the facial mucosa, and root convexity/soft tissue color and texture at the facial aspect of the implant site. 7 White esthetic score (WES) is based on the five following items: general tooth form; outline and volume of the clinical crown; color, which includes the assessment of the dimension*s hue and value; surface texture; and translucency and characterization	—
