Sinus Lifting & Bone Grafting
The maxillary sinuses are located on the right and left sides of the skull at the level of the nose and above the maxillary molars. Its main function is to reduce the weight of the skull and produce mucus.
With tooth loss, aging, or congenital causes, sometimes this sinus membrane hangs down and the bone volume decreases. When the bone height falls below 4 mm, it is not possible to install implant the missing tooth area. Although 4mm long implants can be applied in the lower jaw molar region, 10mm or larger implants should be used in the upper jawbone as the upper jawbone is generally softer and of poor quality.
Sinus Lifting (Sinus Augmentation):
What is it? A sinus lift, also known as sinus augmentation, is a surgical procedure that aims to increase the amount of bone in the upper jaw, specifically in the premolar and molar areas. It’s often needed when there’s insufficient bone height in the upper jaw, or the sinuses are too close to the jaw, for dental implants to be placed.
Procedure:
Closing the Incision: The area is sutured closed. Over time, the graft will integrate with the existing bone and develop into a bone suitable for an implant.
Bone Grafting:
What is it? Bone grafting in dentistry is a procedure where bone or bone-like materials are placed to build and regenerate bone where it’s missing. It’s frequently used when there’s a lack of bone that’s suitable for implant placement.
Types of Bone Graft Materials:
Procedure:
After both sinus lifts and bone grafts, there’s a waiting period before dental implants can be placed. This period allows the grafting material to merge with the existing bone. It can take several months for the bone to be ready for implant surgery, depending on the individual and the extent of grafting.
Benefits:
Post-Operative Care: After the surgery, patients may experience some swelling and discomfort, which can be managed with over-the-counter pain relievers and prescribed medications. It’s also crucial to follow all post-operative care instructions, including dietary restrictions and oral hygiene practices.
In conclusion, sinus lifting and bone grafting are vital preparatory steps for many patients before they can receive dental implants. They ensure that there’s enough bone to support and anchor the implants, leading to long-term success.
