Restoration smile using implants gained incredible popularity over the last decade. This method gives a chance for patients with dentition defects to forget about removable dentures. However, the lateral maxilla is very thin and is located near cortical bone, which is particularly bed for the primary stability of the implant.
Loss of premolars and molars of the upper jaw can result in thinning of the maxillary sinus and post-extraction bone atrophy of the alveolar ridge.
Some doctors advise to avoid interference in the sinus level and place the implant at a distance to the zygomatic jaw bone. In this procedure, short implants are mainly used. Other way implants of standard size cam be set at some angle. However, this methods have many limitations. For example, it is impossible to set implants when the bottom thickness of sinus is of 5 mm. For this reason, sinus lift is carried out for increasing the bone volume. After the transplant window was created in the maxillary, mucosa is separated from the bones, and its cavity is filled with particles of bone graft material.
There are several types of biological material for the sinus lift. For the past decades, autograft was the only way but it has one drawback – the limited access for sampling bone.
Experience has shown that xenogenic bone has excellent osteoconductive properties in dentistry.
Synthetic bone graft substitute Bio3 Beta Bone ™ is reliable material with great resorbability. Its homogeneous structure not only contributes to the formation of new bone tissue, but also ensures its long-term mechanical stability. The high porosity (about 80%) with a pore size of 200 to 800 .mu.m and interrelated structure give high osteoconductivity of Bio3 Beta Bone.
Due to the high macroporosity Bio3 Beta Bone ensures optimum regeneration of bone tissue, so the synthetic material is not worth that the natural material.
