After tooth extraction, healing of the socket takes place with gradual regeneration of bone within the socket. Concurrently, there is loss of apico-coronal height and oro-buccal width of the alveolar ridge due to physiological resorption of the external socket walls, predominantly on the buccal side of the socket (M. G. Araujo & Lindhe, 2005;Cardaropoli et al., 2003). Bone resorption leads to a reduction in the volume of the ridge (Cardaropoli et al., 2006;Schropp et al., 2003). When dental implant therapy is proposed for the replacement of extracted teeth, the post-extraction dimensional changes can hinder the ideal position of the implant for the
