Pre-prosthetic Surgery

What is Pre-prosthetic Surgery?

Pre-prosthetic Surgery is an Oral and Maxillofacial procedure to prepare your mouth before your dentist places a prosthesis (complete or partial dentures). Your denture will sit on the bony ridge. In order to ensure the denture fits well in your mouth and feels comfortable, the bone and tissue area must be the appropriate shape and size. When a tooth is extracted, the area beneath the extracted tooth may be left uneven or jagged. This bone may need to be reshaped or leveled. Sometimes, the bone may need to be removed.

What are Pre-prosthetic Procedures?


•  Removal of excess bone (see Figures 1 & 2)
•  Removal of excess gum tissues
•  Bone ridge reduction
•  Bone leveling and reshaping
Dr. Khayat will determine the appropriate procedure during your evaluation.

Will I be Asleep during the Procedure?

You have several anesthetic options when receiving pre-prosthetic surgery.
 
•  Local anesthesia
•  General anesthesia
•  Conscious intravenous sedation
•  Nitrous Oxide Gas (laughing gas)
•  Oral Sedation






Dr. Khayat will discuss with you the various anesthetic options during your evaluation.

Bone Grafting

Why do I need Bone Grafting?

Your jawbone is stimulated by your tooth roots; much like exercise stimulates your muscles. When you have missing teeth, your jawbone is no longer stimulated by the tooth roots, and it will shrink over time. When this occurs, there may not be sufficient bone required to place dental implants. Bone grafting is also used to repair supporting bone around your teeth that has been damaged by periodontal disease.

What is Bone Grafting?

Bone grafting is a procedure to rebuild bone in the bone deficient areas of your jaw. This allows for the placement of dental implants and for repair of the supporting bone around your teeth damaged by periodontal disease.

What does Bone Grafting Involve?

The bone used in the bone grafting procedure is either taken from your jaw, hip, or tibia (below the knee), or obtained from a tissue bank. Special membranes may be used to protect the bone graft and promote natural healing and bone growth – this is known as guided bone regeneration.

What are the Benefits of Bone Grafting?

By regenerating bone tissue, patients who previously did not qualify for the placement of dental implants due to insufficient bone, can now become candidates for this tooth replacement procedure.

For patients affected by periodontal disease, bone grafting will repair the supporting bone around your teeth significantly improving your oral health. Bone grafting will also increase the stability and strength and increase the longevity of your natural teeth as they will now be supported by adequate bone in your jaw.

Overall, the functionality of your teeth and your esthetic appearance will dramatically improve.
