The use of a protein involved in the creation of the bone to increase the maxillary sinus is the new weapon of researchers from the University of Georgia, United States, to improve the success of dental implants.

Dental implants, screws that hold the permanent teeth prosthetics do not work if the bone in which they are anchored are very thin. Bone wear is a common cause and consequence after tooth loss.

The current solution involves the complete area with bone grafts to stabilize the base of the implant. But this technique is problematic, according to researchers, mainly because it involves additional operations to prepare bone.

In the current study, Ulf ME Wikesjö and colleagues have found that implantation of bone morphogenetic protein (BMP) in the maxillary sinus cause a greater formation of new bone within four weeks of use compared with conventional bone graft

"We found that BMP induced bone formation of a higher quality after the grafts, which improves the chances of implant success," noted Wikesjö. "BMP is phenomenal, because it is a true commodity, with ease of use that can produce real results and could be the new gold standard for this procedure."

According to data from the American Association of Oral and Maxillofacial Surgeons-facial, 69% of adults aged 35-44 years have lost at least one tooth due to dental caries or trauma, and 26% of adults at about 74 years lost all their teeth permanent.

Before dental implants are available, the only options for the replacement of these teeth were dentures and dental bridges, which could lead to bone loss. Implants offer patients many benefits, including good oral health, appearance, speech, convenience, durability and ability to eat.
