Maxillary canines can leave large bone voids when extracted. The loss of this tooth and surrounding bony structures can lead to maxillofacial changes, including “lip catch.” Once healed, mandibular canines can cause trauma to the tissue covering the extraction site or upper lip. The use of bone graft to fill the extraction site can prevent these changes in the maxilla.
The most effective way to fill such a large extraction site is to use a barrier (Ossiflex or Fascia) and particulate bone graft (Periomix).
1. To rebuild the convexity of the maxilla following a maxillary canine extraction, fill the empty alveolus with Periomix. The rebuilding of convexity helps the mandibular canine to fit without catching the lip or traumatizing the surrounding tissues or other physiological structures.
2. VTS’ flexible, natural bone membrane, Ossiflex, or pieces of Fascia can be placed on top of the Periomix to prevent the particulate granules from dispersing and facilitate bone healing under the protection of a barrier. This is known as Guided Bone Regeneration.
3. Once the particulate and soft tissue or membrane are in place, close the flap created for the extraction. Then, proceed to full closure.
