Bone Regeneration

Sinus Augmentation

This procedure is used in the upper arch to increase bone height for implant placement. When back upper teeth are lost, the sinus will enlarge, leaving minimal bone height. This is an issue for patients seeking a fixed replacement of teeth. The following are the two most common procedures used to rebuild the bone for dental implant placement.

Lateral Wall Sinus Augmentation 

With this procedure, an incision is made near the upper premolar or molar region to expose the jawbone.  A small opening is cut into the bone and the membrane lining the sinus on the other side of the opening is gently pushed upward.  The underlying space is filled with bone graft material and the incision is closed. The bone used for this procedure may be from your own body (autogenous graft) or a cadaver (Allograft).  Sometimes the dentist might use synthetic materials, which can also stimulate bone formation. The implants are placed after healing has occurred; the timeline will depend on the individual case. Sinus augmentation has been shown to increase the success of dental implant procedures.

Vertical Sinus Augmentation

This procedure involves raising the sinus membrane through the crest of the bony ridge or through a socket of a recently extracted tooth. The bone of the sinus floor and sinus membrane are lifted using specially designs instruments. The sinus floor and sinus membrane are lifted gently through tapping the specially design instruments (ostetomes). Once the sinus floor and membrane is lifted to the desired height a collagen membrane is placed, followed by bone and another collagen membrane. The gum tissues are closed over the surgical site and sutured.
