Immediate Implant Placement in Type ii Socket by Vestibular Socket Therapy Using Collagen Membrane

Background: Immediate implant placement has become a routine and regular clinical practice. When the labial bone plate develops a dehiscence-type defect, delayed implant placement was recommended to give suitable amount of time for soft tissue thickening. However, it has a number of drawbacks, including a lengthy treatment period, the requirement for two surgical procedures, and a potential loss of facial contour. When immediate implant is placed with flap elevation and guided bone regeneration in type II socket, labial bone augmentation results were satisfactory, but in terms of soft tissue, it led to midfacial recession and loss of soft tissue contour, resulting in a compromised final esthetic result. To reduce these drawbacks, implant can be immediately placed by vestibular socket therapy using collagen membrane. Aim of this study: To compare labial bone augmentation in immediate implant placement in type II extraction sockets by using collagen membrane placed by two different modalities.
