Sinus Augmentation

Sinus Augmentation with The Best Orange County Periodontists with More than 15 Years of Experience!

The maxillary sinuses are the largest of four paranasal sinuses. The maxillary sinuses are empty, air-filled space with average volume of 15ml, which are located behind your checks and on top of the upper teeth. The roots of natural upper teeth extend up into the maxillary sinuses and are usually separated from maxillary sinuses by a thin wall of bone. When these upper teeth are loss or extracted, the volume of sinus cavity increases due to decrease in height, width, and density of bone at the base of sinus and the sinus relocates to more apical, a condition called pneumatization. When dental implant is inserted in this area, the initial implant stability is poor coupling with inadequate bone height for the implant length. This result in implant failure either initially or during loading.

The solution to this condition is called a sinus lift or sinus augmentation at top dental office in Mission Viejo, Aria Dental. Our periodontists at Aria Dental perform this procedure to elevate maxillary sinus membrane upward and placing a donor bone graft into the floor of your sinus and above your upper jaw in the area of molars and premolars. The end result is the improved bone height in the posterior maxilla, which is more favorable for implant placement.

If enough bone between upper jaw ridge and the bottom of the sinus is present to stabilize the implant well, sinus lift or augmentations and implant placement can sometimes to be performed as a single procedure. If enough bone does not exist, the sinus life will have to be performed first, and graft will have to mature for several months before implants are placed.

Type of Bone Graft Materials for Sinus Lift

Several different types of bone-grafting materials can be utilized:

Who Is a Candidate for Sinus Lift?

Sinus Lift Procedure

The maxillary sinuses are in the cheekbone, just below the eyes. As seen in the picture, the tooth is supported by the original bone.

Tooth loss below the sinus leads to bone loss and overtime the sinus will expand into the area previously occupied by the bone and teeth.

In this picture, the decrease of the maxillary sinus can be seen by extraction or tooth loss. The surgeon will correct the sinus to its original state for the correct placement of the dental implant.

If a dental implant is placed into inadequate bone, it will move, shift, and fail because there is not enough stability to withstand forces of biting and chewing.

A sinus lift procedure begins with a temporary opening made in one of two possible areas as seen in this picture.

An instrument then modifies the sinus to previous position, providing clearance for the placement of substitute bone.

The required amount of bone is added in the maxillary sinus, to provide enough stability and thus proceed to the dental implant placement.

Over time, the implant and substitute bone will heal, creating a strong bone and stable foundation for your teeth.

Finally, the implant placement process is completed, and the result is successful. The lifting has solved the original issue.
