Management of peri-implant soft tissues between tooth and adjacent immediate implant placed into fresh extraction single socket : a one-year prospective study on two different types of implant-abutment connection desi

This prospective study has been designed to evaluate the correlation between the presence/absence of the interproximal papilla and the mesio-distal and corono-apical position single-tooth replacement implants inserted immediately following tooth extraction. These distances have been evaluated measuring the horizontal distance between the implant and the adjacent tooth (implant tooth distance, ITD) and the vertical distance between the contact point and the coronal margin of the interproximal bone (contact point-bone distance, CPB)
