Vestibular Socket Therapy (VST) in Infected and Non Infected Sockets

A 1-cm long vestibular access incision was cut, 3-4 mm apical to the mucogingival junction of the involved tooth. The socket orifice and the vestibular access incision were connected by a subperiosteal tunnel that was created using a periotome and a micro-periosteal elevator. Implants were installed using a CADLCAM surgical guide. A flexible cortical membrane shield of heterologous origin, 0.6 mm in thickness was prepared by hydrating and trimming it. It was then tucked through the vestibular access incision, till it extended 1 mm below the socket orifice, and stabilized using a membrane tack ( to the apical bone. The gap between the implant and the shield/the labial plate was then filled with particulate bone graft \[75% autogenous bone chips harvested form local surgical sites and 25% inorganic bovine bone mineral matrix.
