Understanding Ridge Expansion or Modification
Why Ridge Expansion or Modification is Needed
- Missing teeth: The moment a tooth is lost in the mouth, the body starts to naturally stop supporting the bone in the area, leading to 25 percent bone loss within a year and up to 40 percent within three years.
- Periodontal disease may lead to tooth loss and bone loss in the mouth.
- Smoking is a big risk factor for periodontal disease with some studies showing heavy smokers with five times more severe bone loss compared to those who have never smoked.
- Misaligned teeth that affect normal chewing can lead to bone loss.
- Trauma can lead to missing teeth and bone loss.
- Wearing dentures can cause bone loss because of a lack of pressure applied to the bone when chewing.
- Other developmental issues can lead to bone loss.
Steps in a Ridge Expansion or Modification
Steps for a ridge expansion:
- The gum is lifted away from the bony ridge to expose the defect area.
- The defect is then filled with bone from a healthy spot in the patient or a bone substitute. These materials build up the ridge.
- The incision is then closed to allow healing to begin.
