The vertical and horizontal buccal bone resorption were measured 6\u2010months following implant placement. The esthetic outcomes were evaluated by assessing the Pink Esthetic Score (PES) and the amount of midfacial mucosal alteration, in addition to patient satisfaction assessment through a Visual Analogue Scale (VAS) based questionnaire 1\u2010year following implant restoration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The present study showed that the socket shield group yielded significantly less vertical and horizontal buccal bone resorption of 0.35 (\u00b10.62) mm and 0.29 (\u00b10.34) mm compared to 1.71 (\u00b11.02) mm and 1.45 (\u00b10.72) mm in the xenograft group respectively. Also, there was a significantly greater midfacial mucosal recession in the xenograft group of 0.466 (\u00b10.58) mm compared to midfacial mucosal coronal migration of 0.45 (\u00b10.75) mm in the socket shield group.
