Sinus Lift Surgery may be suited to people with weak upper jawbones, whereby immediate dental implant treatment is not an appropriate option for teeth replacement due to the weakened condition of the jawbone. Having sinus lift surgery helps to prepare the jawbone for further treatments, such as dental implants.
Dr. Ehab’s Dental Clinic in Dubai provide sinus lift surgery to improve oral function and provide an aesthetically pleasing look. It involves the oral surgeon shifting the sinus membrane upwards so that a bone graft can be inserted between the maxillary sinuses and upper jawbone. The bone graft procedure allows the upper jawbone to be strengthened and made suitable for dental implant treatment.
Oral surgeons perform sinus lift surgery and bone grafting procedures, which are sometimes referred to as “sinus lift bone augmentation”. Patients with upper molar loss caused by trauma or periodontal disease can benefit significantly from these procedures.
Building up the upper jawbone through sinus lift and bone grafting procedures restore bone loss caused by resorption, particularly in patients teeth have been absent for lengthy time periods. Sinus lift bone augmentation allows patients a chance to have tooth replacements, enhancing dental function and improving smile aesthetics.
People who have had teeth extracted due to infection may be able to have their teeth restored through sinus lift surgery. Those that delay treatment for missing teeth may experience bone loss of up to 60 percent, if left for three years post dental surgery. The delay in treatment accentuates oral trauma and bone loss, which makes dental implant treatment unsuitable. Sinus lift surgery is a means of restoring bone capacity for receipt of dental implants.
Where the maxillary sinus and upper jawbone are in too close proximity, insertion of titanium dental implants without sinus lift surgery may cause damage to the jawbone structure or the sinus cavity region. In cases where sinus lift surgery is necessary, both sinus lift and bone grafting procedures may need to be performed first.
Individuals are initially examined to determine if sinus lift procedures are necessary. X-rays and diagnostic imaging, such as cone beam CT scans, are done to identify if the maxillary sinus and upper jawbone are too closely connected. This requires clinicians highly trained in sinus, bone and jaw function, with assessments of jawbone density and capacity, and evaluations of sinus condition for treatment.
Once patients consent to treatment both the sinus lift and bone augmentation procedures are performed. Sinus lift surgery involves lifting the sinus membrane lining, so that the membrane is raised into the sinus cavity. The space created through lifting the sinus membrane lining allows for fitting of the bone graft and later the dental implant fixture. Once the bone graft is done the tissue is sutured unless dental implants are inserted there and then.
When sinus lift surgery and bone augmentation are complete, dental implant treatment can proceed. Preparation for dental implant fixtures may be completed during sinus lift surgery or can be completed afterwards.
Clinicians use their experience and discretion to determine the suitability of inserting dental implants during a sinus lift operation. In most cases the sinus lift bone augmentation is completed first, after which there is a six to nine month healing period. The length of time for healing depends on the kind of bone graft, and there is usually no scarring present after healing.
Bone grafts can come from different sources, such as bone harvested from the patient’s own mouth or from their tibia or hipbone. The patient’s bone is normally better to use because there is less chance of rejection and greater potential for bone graft fusion. However, bone grafts may come from other humans or animals, such as cows.
Other human bone grafts are frozen before use and animal bone is usually obtained through a tissue bank. Patients are able to express a preference in the type of bone graft used for sinus lift bone augmentation. Some also opt for synthetic bone because they prefer not to have a personal, human or animal bone graft.
With research into the development of growth factor proteins for medical use, clinicians are also harvesting growth factor from patient’s blood and mixing them with grafts to better facilitate bone growth and strengthening. These growth factor proteins enable faster bone formation and recovery. In some cases grafting is not required because bone formation from growth factor proteins is sufficient.
Patients may experience some inflammation in the sinus region after sinus lift surgery. Some patients may also notice nose or oral bleeding. You will be advised against nose blowing and sneezing if possible, to avoid loosening the sutures and potentially the bone graft.
People prone to seasonal allergies will need to exercise particular care and, where appropriate, use anti-allergens for relief. Medications are available to reduce sneezing risk, such as nasal sprays that also act to keep the inner nose moist.
