When a patient has had no upper teeth for many years, they will have extreme upper bone jaw loss. The maxillary alveolar ridges of such patients show severe bone resorption, and it is difficult placing a fixed prosthetic device. These patients tend to have inadequate bone available for good anchorage for the titanium implants for fixed prosthesis.
The most common way of treating such patients is by doing sinus bone augmentation using bone grafting procedures by surgery.
The most effective way of bone augmentation is by using autogenous bone in grafting procedures. The use of autogenous bone allows for the transfer of living osteogenic cells to the grafted bone. However, this procedure has disadvantages because this procedure requires second invasive surgery on the patient for autogenous bone harvesting. Increased morbidity in the patients can occur, and prolongs treatment time and causes additional expense to the patient. The problem is it may be difficult to harvest enough autogenous bone from intra-oral sources to fill the bone defect.
To avoid this situation, some surgeons like to use alternative grafting material such as processed bovine bone. Called Bio-Oss, this natural cow bone mineral is chemically similar to human bones. The Bio-Oss acts as an excellent scaffold to promote new bone growth in the patient’s jaw. However, the success rate of this procedure varies widely among different dental Surgeons. The procedure requires a watertight closure for the bone graft area and can take up to 10-months to heal.
Dr. Jonathan Penchas uses the latest technique called the Zygoma Implant Procedure to solve the problem. This procedure presents an alternative for rehabilitating the patients with resorbed upper maxillary ridges. This method requires only ‘one’ surgical procedure and without the need for grafting. Furthermore, the healing time is short, and the success rate is as high as 96.8%.
Working with the best oral surgeons in the area, Dr. Penchas can make the process easier for the patient.
Zygoma Implant Technology uses a zygomatic bone as a base to provide predictable anchorage for the screw-shaped titanium implants. The zygomatic bone has dense bone quality and acceptable bone volume to provide the most predictable anchorage.
Along with the Zygoma Implants, the dentist places two to four standard implants into the anterior maxilla.
Then the Zygoma Implant Fixture penetrates the sinus bone and anchors in the zygomatic bone. The Zygoma implant fixture emerges in a palatal position in the molar area of the upper jaw.
Within a day of the Zygoma Implant surgery, the patient can receive a permanent implant bridge. The result is beautiful new teeth with minimal surgical trauma and maximum oral function. And no one can tell the difference, whether it is your natural teeth or implant fixed restoration! A Zygoma Implant is for patients with sinus problems. Make sure that your maxillary sinus is clinically symptom-free and disease-free before you decide to undergo Zygoma Implant procedures.
