Ridge and sinus augmentations are surgical dental procedures used to fill in areas of the gum line and underlying bone that have deteriorated as a result of tooth loss or extraction. Specifically, a ridge augmentation refers to the reconstruction of degenerated or underdeveloped gums, and a sinus augmentation refers to an enhancement of the amount and consistency of the maxillary jaw bone by lifting the sinus floor and grafting bone into the jaw line. These state of the art procedures are capable of restoring a natural appearance to, as well as making it possible for some patients to qualify for dental implants.
Did you know…
that tooth loss is not the only reason for getting a ridge or sinus augmentation? Many patients have deteriorated gum lines or inadequate jaw bone support caused by oral diseases, such as periodontal disease, or a physical trauma to the face. Others experience bone atrophy caused by prolonged denture wear. By grafting in bone and building up the gum line, a dentist can make it possible for a patient’s jaw and gums to support permanent dental implants.
Frequently Asked Questions
What is sinus lift surgery?
Sinus lift surgery, also known as sinus augmentation, is a procedure performed to increase the amount of bone in the upper back portion of the jaw. This area often has limited bone height due to bone resorption following tooth loss and the natural expansion of the maxillary sinus over time.
Why might a sinus lift be necessary before dental implants?
Dental implants require adequate bone support for long‑term stability. When there is insufficient bone beneath the sinus cavity, a sinus lift procedure can create the additional bone volume necessary for secure implant placement.
How is sinus lift surgery performed?
Sinus lift surgery can be performed using different techniques depending on the amount of existing bone. In some cases, a lateral window approach is used to access the sinus and place bone graft material beneath the sinus membrane. In other situations, a crestal approach may be performed through the implant site to gently elevate the sinus membrane and add graft material.
How long does healing take after sinus lift surgery?
Healing time varies depending on the amount of bone added and the individual patient. In many cases, dental implants can be placed after several months once the grafted bone has integrated with the surrounding jawbone.
Is sinus lift surgery a common procedure?
Sinus lift surgery is a well‑established procedure commonly performed to allow dental implants to be placed in areas where bone height would otherwise be insufficient.
What should I expect after sinus lift surgery?
Swelling and temporary discomfort are common after sinus lift surgery as part of the normal healing response. Most patients recover uneventfully when post‑operative instructions are followed and the surgical site is allowed adequate time to heal.
