Comparing the esthetic results and efficiency of 2 treatment protocols: the conventional approach using provisional crowns to sculpt the soft tissue before fabrication of the final crown, and a faster protocol, in which the final crown is finished directly without provisional crown phase.

Primary Outcome Measures

Name	Time	Method
1. Esthetic outcome is measured using the PES/WES”: which is an esthetic index described by Belser in 2009 which is done by taking photographs (the photographs are examined and given points to different parameter, such as papilla fill, texture of soft tissue, volume, or color of soft tissue) at each follow up appointment<br>2. Volumetric changes is measured using digital models of the site of interest through the intraoral impression system

Secondary Outcome Measures

Name	Time	Method
1. Biologic soft tissue outcomes is measured by registering the PPD (periodontal pocket depth), bleeding, and plaque around the implant crown at the follow up visit, which we would do anyway in routine control visits after crown placement<br>2. Biologic hard tissue outcomes is measured by registering the bone level changes: a small periapical radiograph is taken to evaluate bone level changes around the implant crown at the follow up visit<br>3. Efficiency comparison of the 2 protocols measured registering the time it takes in each procedure, and adding the time for all the procedures in the same protocol group. After, once the esthetic outcomes have been summed up, we may discus if the higher efforts of the control group was worth it.<br>
