Marginal Bone and Soft Tissue Alterations After Use of OsseoSpeed EV Profile Implants

Evaluation of the marginal bone and soft tissue alterations after the OsseoSpeed™ EV Profile implants placement in anterior maxilla. The following parameters will be tested: * pink esthetic score - at the temporary crown delivery, at the final crown delivery, 6 months post final crown delivery * papilla index - at the temporary crown delivery, at the final crown delivery, 6 months post final crown delivery * changes in radiographic marginal bone levels and width at buccal and palatal aspects: differences between baseline (the day of surgery) and 1-year post-op measurements on CBCT will be made.
