What is it?

This surgical procedure brings back any jaw bone that has gone missing from a tooth extraction. After an extraction, the root of the tooth is open and will gradually collapse- resulting in bone loss. Shockingly, the amount of bone loss can be up to 40% in only six months, and will continue to increase as time passes.

This is where bone grafting comes into play because you may be in need of an implant but do not have sufficient bone to sustain one. Bone grafting is used to build back that missing bone and create a strong anchor for the dental implant.

How is it done?

  • The gums are cleaved so that a flap is created and the bone can be exposed.
  • The areas that have lost bone are filled with the bone substitute.
      1. The bone substitute can consist of your own bone, donated bone, synthetic bone, and animal (cow) bone.
  • A dissolvable membrane will be placed over the treated area, and the flap will be placed back and sutured to its original position.
  • Over a period of 6-10 weeks, the membrane will dissolve and the substitute bone will mature and regenerate into new bone.
  • Once the bone has regenerated, you now have a solid foundation for a dental implant.

Ridge Expansion

A ridge expansion is surgical procedure that increases the amount of bone on the jaw ridge where a tooth is missing.

When is it needed/ Risks of not getting it done?

  • Once a tooth has been extracted, the bone that previously held the tooth is left dormant. Overtime, the body will reabsorb the bone and cause the jaw ridge to recess.
  • A ridge expansion is the procedure entailing the restructure of the jaw ridge so that it is prominent enough to support a dental implant. If the recessed ridge is ignored, the body will not stop reabsorbing the bone and will cause the pocket to continue deepening.

How is it done?

  • First, the dentist will cleave the gum tissue to expose the jaw ridge.
  • Next, a space will be inserted into the jaw ridge and filled with bone grafting material.
  • Lastly, the gum tissue is sutured back to its original position.

We will then wait for the inserted bone material to mature and develop into new bone. Once the bone has matured, we can then proceed with the dental implant.

Sinus Lift / Sinus Augmentation

What is it?

A sinus lift is a surgical treatment to the maxillary region of the mouth, whereby the amount of bone above your molars and premolars is increased to provide a strong foundation for an implant.

When teeth are missing in the upper back jaw bone, the body will continuously reabsorb the existing bone back into the body and if this is not addressed the gum pocket will continue to deepen. Patients who are missing teeth or are experiencing significant loss of their jaw bone will likely be recommended a sinus lift.

Another implication that involves a sinus lift is when a patient’s sinus is located too close to their upper jaw bone’s base, and thus will require additional bone to separate the two.

How is it done?

  1. First, the gum tissue in the upper back jaw region is cleaved so that the underlying bone is exposed.
  2. Second, the dentist creates a tiny opening in the bone which exposes the sinus tissue- the tissue is then detached from the bone and lifted upwards. This upward push of the tissue creates the room for the bone grafting substance to be inserted.
  3. The bone grafting material is inserted into the opening.
  4. The gum tissue is then brought back and sutured to its original position.
  5. Next, we will invite you back to Riverpark Dental 7-10 days later so we can have a look at the sutured area’s.
  6. The stitches will be removed at this second visit if they have not been absorbed.
  7. Now that there is adequate bone available to do the dental implant, we will need to wait for a period of approximately four to nine months to pass for the new bone to mature and form from the bone grafting material.
