A maxillary implant is an implant that is placed between the jaw and the maxillary sinuses. It is inserted during a sinus lift or augmentation, and is used to increase the amount of bone to support dental implants. [1] Implants are either inserted after drilling, or by using a non-drilling method known as the osteotome technique. [1]
Xray showing a sinus lift in the left upper jaw Sinus lift surgery, 3D Illustration. Maxillary sinus floor augmentation [1] (also termed as sinus lift, sinus graft, sinus augmentation, or sinus procedure) is a surgical procedure that aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian ...
Functional endoscopic sinus surgery (FESS) is a procedure that is used to treat sinusitis and other conditions that affect the sinuses. Sinusitis is an inflammation of the sinuses that can cause symptoms such as congestion, headaches, and difficulty breathing through the nose.
It was described by George Caldwell in 1893 and Henry Luc in 1897. They describe the operation of maxillary sinus diseases via canine fossa. Functional endoscopic sinus surgery is the standard surgery for maxillary sinusitis nowadays. [10]
Once access to a blocked sinus is confirmed, a balloon catheter is advanced over the guide wire and positioned in the blocked sinus opening for inflation. The balloon is inflated. The entire procedure takes around 31 minutes and if the procedure is successful, the sinus will remain open after the balloon is deflated and removed for up to 24 months.
The GBR principle was first examined by Dahlin et al. in 1988 on rats. The selective ingrowth of bone-forming cells into a bone defect region could be improved if the adjacent tissue is kept away with a membrane; this was confirmed in a study by Kostopoulos and Karring in 1994. GBR can be used for bone regeneration on exposed implant coils . [4]
The minimal bone height for a standard implant placement in the posterior region of the upper jaw should be about 10 mm to ensure acceptable implant survival. [3] When there is inadequate bone available, bone grafting procedures and sinus lift procedures may be carried out to increase the volume of bone.
4) Through careful instrumentation, the membrane is carefully peeled from the inner aspect of the sinus cavity. 5) The membrane has been reflected from the internal aspect of the inferior portion of the sinus cavity; one can now visualize the bony floor of the sinus cavity without its lining membrane (note the triangular ridge of bone within ...
