Bone Grafting for Implants

Do I have enough bone for dental implants?

After a tooth is removed, the extraction socket begins a remodeling process and can shrink over time. In order to prevent this and ensure optimal results, bone grafting can be used at the time of tooth extraction to maintain the width and volume of bone needed for future implant placement. This is commonly referred to as socket preservation.

If a tooth was removed many years ago, the remaining ridge may be very thin and have insufficient bone volume for implant placement. For these scenarios, a bone graft can be placed adjacent to the thin ridge to augment and improve the overall bone volume. This is referred to as ridge augmentation and is comfortably performed in the office. The bone graft is allowed to heal for 4 to 6 months, and the implant can then be placed into the new ridge.

As we get older, the sinuses in the top jaw enlarge and can extend into the tooth-bearing areas of the jaw. Although this is a natural part of the aging process, the amount of bone available for implant placement may be limited. During the sinus lift procedure, the sinus membrane is delicately elevated, allowing a bone graft to be placed and restoring the bone volume necessary for implant placement. With the advanced techniques used at Avos Dental Specialists, the sinus lift procedure can frequently be completed at the same time as implant placement.
