When there is loss of the posterior teeth, excessive force is placed on your remaining teeth. To correct this problem, dental implants and crowns can be utilized.
Due to the position of the sinus in the upper posterior regions, it may be too low for dental implants to be placed correctly.
The sinus floor is re-positioned to create adequate space for an implant to be positioned correctly. This is a simple procedure. To help stabilize the dental implant, a variety of grafting materials are utilized to promote your bone to grow more rapidly. As the bone grows, it gradually replaces the grafting materials.
In certain cases, a simpler procedure can be performed. If applicable, the remaining bone under the sinus floor is gently pushed up, thereby elevating the floor of the descended sinus. Following this step, bone replacement materials are positioned under the lifted bone. This grafting material will be replaced as new bone grows in the area.
Sinus augmentation procedures have a high success rate. Several studies report over a 95% success rate. After the healing of the sinus augmentation, typically 6-10 months, the implants will be placed in a predictable and successful manner.
In cases where sinus augmentation does not produce enough bone for the implant placement, a second sinus augmentation may be needed to regenerate more bone.
