Sinus Augmentation
What is a Sinus?
The maxillary sinuses are behind your cheeks and on top of the upper teeth. These sinuses are empty, air-filled spaces. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. When these upper teeth are removed, there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.
The Sinus Augmentation Procedure:
The key to a successful and long-lasting dental implant is the quality and quantity of jawbone to which the implant will be attached. If bone loss has occurred due to injury or periodontal disease, a sinus augmentation can raise the sinus floor and allow for new bone formation.
In the most common sinus augmentation procedure, a small incision is made on the premolar or molar region to expose the jawbone. A small opening is cut into the bone, and the membrane lining the sinus is pushed upward. The underlying space is filled with bone grafting material, either from your own body or from a cadaver. Sometimes, synthetic materials that can imitate bone formation are used. After the bone is implanted, the incision is stitched up and the healing process begins. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in this new sinus bone.
If enough bone between the upper jaw ridge and the bottom of the sinus is available to stabilize the implant well, sinus augmentations and implant placement can sometimes be performed as a single procedure. If not enough bone is available, the sinus augmentation will have to be performed first, then the graft will have to mature for several months, depending upon the type of graft material used. Once the graft has matured, the implants can be placed.
The sinus graft makes it possible for many patients to have dental implants when years ago there was no other option besides wearing loose dentures.

Jessica Grimmett2021-09-16I was very impressed with Dr Cho and his staff! Very organized and efficient. Ashleigh is amazing! Totally on top of everything. I had crown lengthening done and the experience was great! No pain at all and Dr Cho walked me through everything so I knew what was happening and what to expect next. Ariel and Dr Cho work great together! They gave me post op instructions verbally and Ashleigh also gave me instructions on paper so I know how to care for the area when I get home. I will definitely refer my friends and family to Dr Cho in the future!

Pantelis Vassilakis (acousticslab)2021-02-04Dr. Cho was thorough, quick, clear, and direct in his exam and assessment of our daughter, visiting for a possible labial frenectomy. He has earned our full trust. Highly recommended. The front office is efficient as courteous. The entire operation is a caring, effective, and efficient well-oiled medical machine :-). Congrats!
Kirsten Davis2021-01-21I have been going to Dr. Cho for at least the last 5 years, and I highly recommend him and his practice to everyone I know who's looking for a quality periodontist. After many years of getting the run-around or getting too short "perio quadrant scaling cleanings" from traveling periodontists working with NO oversight from the dental providers they partner with, I finally realized that I needed to find someone with extra expertise and integrity. I feel Dr. Cho has both. I have had regular cleanings, deep cleanings and 1 implant surgery with him. Very happy with his care!

JT “Answerman20000” Y2020-12-01Dr. Cho cares about each patient and recommends the right procedure and considers the cost to the patient. His work is thorough and answers all questions asked. He also asks questions to understand why they are visiting his practice and any background before making any recommendation. He made me feel very comfortable and I felt he was the Periodontist for me..
