Dramatic improvements have been made in regeneration of lost bone. Situations where this is useful include bone loss around natural teeth, bone loss around implants and bone loss in preparation for future placement of dental implants. The principles are the same and results have been more predictable than ever before.
BIOLOGIC PRINCIPLES OF TREATMENT
Bone heals more slowly than the gum tissues in the mouth. Without Guided Bone Regeneration techniques that separate bone from gum t issue, the faster healing gum would prevent the bone from maximizing its full healing potential following surgical procedures. The concept of treatment is simple. A membrane is placed between the gum and bone which acts as a barrier. This barrier prevents downgrowth of the gum into the underlying bone as it heals. Usually a bone graft is placed into the underlying bony irregularities, under the membrane, to help the body grow new bone. Membranes around teeth are typically designed to dissolve away after several weeks of healing have passed. Membranes used to restore bony ridges in association with implant therapy are typically non-resorbable, and must be removed at a later date.
