Bone Grafts and Sinus lifts

Bone Grafts

What is a Bone Graft?

Over a period of time, the jawbone associated with missing teeth atrophies or is dissolved. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants.
Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place dental implants of proper length and width, it also gives us a chance to restore functionality and esthetic appearance.

Why would I need Bone Grafting?

Bone grafting can repairimplant sites with inadequate bone structure due to previous extractions, gum disease or injuries. Bone grafts can include socket preservation after an extraction, ridge expansion when the width of the jawbone has diminished or sinus lifts when there is not enough bone between your upper jaw and the maxillary sinuses.

What is a Sinus Lift?

Sinus Lifts, also called sinus augmentation, are performed to replace bone in the posterior upper jaw when more bone is needed for placement of a dentalimplant. There are two types of sinus lifts performed in our office; a “Closed” sinus lift and an “Open” sinus lift.
Closed” sinus lifts add bone to your upper jaw in the areas over your molars and premolars. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called Guided Bone Regeneration (GBR) or Guided Tissue Regeneration (GTR).
In an “Open” sinus lift; we can access the maxilla (upper jaw) from the side to lift the membrane of the sinus upward to place additional bone.Implants can be placed simultaneously or at a later date; depending on the amount of bone you start with. Sinus lift bone healing can take approximately 8- 12 months.
Dr. Lynn Pierri utilizes the PiezoSurgery® device for “Open” sinus lifts, which has been developed to overcome the limits of precision and intraoperatory safety existing in traditional bone cutting instruments. PiezoSurgery® allows the doctor to obtain high predictability and low morbidity in bone surgery. Thanks to the controlled three-dimensional ultrasound microvibrations, the PiezoSurgery® technique opens up a new age for osteotomy and osteoplasty in Implantology, Periodontology, Endodontics, and surgical Orthodontics.PiezoSurgery® offers micrometric cutting action, minimum soft tissue damage, maximum intra-operative visibility and excellent tissue healing.

Bone Morphogenetic Protein (BMP)

Bone Morphogenetic Protein is also used in repairing bony defects and sinus lifts in preparation for dental implants. BMP is a group of growth factors with the ability to induce the formation of bone from your own body’s physiology. For additional information on BMP, visit on the web.

Should I have any of these procedures done with I.V. Sedation or General Anesthesia?

Some bone socket preservation procedures can be performed with local anesthetic. More involved procedures such as sinus lifts and socket preservation done in conjunction with extractions may require sedation. Dr. Pierri will discuss all of your options with you so you can make an informed decision. If sedation is used; our Board Certified M.D. Anesthesiologist will place you in a restful sleep while Dr. Lynn Pierri performs this procedure.

What happens after surgery?

After surgery our Post Anesthesia Care Unit (PACU) Certified Registered Nurses will care for you in our recovery room and prepare you for your post-operative period at home. The nurse will provide you and your driver with detailed printed instructions on:

  • how and when to take you medications
  • using the provided ice-packs
  • a suggested diet to follow during your recovery period
  • when you can resume exercising
  • after-care instructions and general precautions
  • when you can start brushing your teeth and rinsing
  • and, will answer any additional questions you may have
