Bone Graft and Sinus Lift
Don't have enough bone for an implant? We can help!
When a tooth is removed, the area of bone that the tooth had occupied recedes over time. This often results in a sunken appearance in the face. Previously, this loss of bone meant that you were unable to have an implant placed securely in your jaw, however recent medical advancements have made this a thing of the past and bone can now be regenerated as needed.
A bone graft is procedure that helps rebuild bone. In dentistry, it is used to increase the thickness of the bone in your upper or lower jaw so that it may facilitate the successful placement of a dental implant.
A bone graft involves the use of two kinds of materials:
- Particulate bone graft material: Small chips of a bone substitute is used to fill spaces where bone is found to be deficient. We use brands such as Bio-Oss, Bond Bone, MinerOss or Bio-Oss Collagen.
- Protection of the graft: The graft is covered with a resorbable membrane that keeps everything in place while the area heals and strengthens. We use membranes such as Bio-Gide, L-PRF or MemLok.
The time is takes for a bone graft to become ready for implant placement varies between patient to patient, but usually it takes about three months.
Sometimes dental implants are required for replacing the upper back teeth. For most people, there is enough bone in the upper maxilla to facilitate the placement of an implant. For those that do not, a sinus lift is required. This situation arises due to there not being adequate bone thickness in the upper jaw to allow placement of a dental implant. Thankfully, this kind of problem can be easily overcome with the help of a surgical procedure called a ‘sinus lift’, which we offer at Clear Choice Dental!
A sinus lift is a very delicate procedure, and it needs to be performed by an experienced dentist to ensure greater success. At Clear Choice Dental we use a technology called Piezosurgery to accomplish the sinus lift with more success, precision, comfort and safety. It involves inserting bone graft material into the sinus, where it hardens over time. You won’t have to worry about there being any discomfort during the procedure as we have IV sedation facilities available to us. In addition, we issue post-operative instructions for the first week of healing so you can quickly resume your regular routine.
Sinus lift for people with one or several missing teeth:
Depending on the thickness of bone present in the upper jaw below the sinus, your dental implant may or may not be inserted during the sinus lift procedure. In cases where there is at least 3mm of bone present, the implant can be inserted in the same procedure. In other cases where the bone is less than 3mm, it is essential that the sinus lift is performed before implant placement so the bone graft can mature and strengthen. In most cases, bone maturation takes about 5 to 6 months.
A sinus lift is one of the options available for people who wear full dentures and wish to change to a full implant bridge restoration. In cases where there is a minimal amount of bone left in the upper jaw as a result of periodontitis, gum disease or tooth loss, it becomes essential to perform a sinus lift. The patient will have to wait 5 to 6 months for the bone graft to strengthen, and then once it’s healed the implants can be placed. In the case of a patient using complete dentures, they would not need to stop wearing them during the healing process.
What are the alternatives available to bone grafts and sinus lifts?
For those patients who need a single tooth replacement or multiple teeth replacement in the maxillary sinus region, and want to avoid having a sinus lift, can use a shorter, specially designed implant. This can achieve the same desired result, however, the procedure calls for a more delicate approach to the implant insertion.
A zygomatic implant is another option that avoids having to perform a sinus lift. Zygomatic implants are inserted into the cheekbone, and are generally longer than standard implants for increased sturdiness. This type of implant is used when a previous bone graft or standard implant fails, or if the patient is unable to have a sinus lift due to other medical reasons.
