Bone & Tissue Grafting

 Grafting is a procedure used to replace/ restores missing bone and gum tissue.

Bone Grafting : Bone grafting is the replacement or augmentation of the bone around the teeth.

Why is bone graft needed : Bone grafting is performing to reverse the bone loss/ destruction caused by periodontal disease, trauma, or ill fitting removable dentures. It is also used to augment bone to permit implant placement, such as augmenting bone in the sinus areas for implant placement, or augmenting bone to enhance the fit and comfort of removable prosthesis, or to enhance esthetics of a missing tooth site in the smile zone. When one loses a tooth, as in an extraction, the surrounding bone collapses. To preserve this bone for future implant placement or for esthetics, bone graft is used.

Guided Bone Regeneration (GBR) : Refers to procedures that attempt to regenerate bone prior to the placement of bridges or more commonly implants. This is accomplished using bone grafts and biocompatible membranes that keep out tissue and allow the bone to grow.

Gum grafting : A gum graft is used to replace missing and/ or receded gum tissue.

Causes of gum recession :

  • Aggressive and/ or Faulty brushing.
  • Excessive biting forces- This can result in bending/ flexing of teeth, which will after result is fracture of a small portion of tooth structure at the gum line and consequently bone and gum recession.

Barrier membranes : In conjunction with bone grafting membranes are often used to help stabilize the bone graft as well as displace the gum tissue at a much faster rate than bone, therefore, membranes are used to prevent gum tissue from growing in and displacing the bone graft before it matures.
