About

this study compares 2 techniques in guided bone regeneration for horizontal ridge augmentation in aesthetic zone

Full description

Guided bone regeneration is a technique for ridge augmentation using membranes The membrane of GBR is an essential component of treatment as it has some important characteristics manageability, space-making ability, and adequate mechanical, physical properties, and biocompatibility Collagen membranes are the most commonly used and can inhibit soft tissue growth in bone defects and achieve better wound healing and bone regeneration.

on the other hand, a Vascularized inter-positional periosteal connective tissue flap is a flap that has been used as a substitute for the collagen membrane with promising results. Vascularized inter-positional periosteal connective tissue flap (VIPCTF) may have many advantages over traditional collagen membranes such as; high vascularity, decreased cost (as it may substitute membrane), providing an increase in soft tissue thickness, and reusability.

So Evaluation of effect of vascularized interpositional periosteal connective tissue flap on horizontal ridge augmentation grafting of the anterior maxilla in comaprison with the collagen membranes
