Sinus augmentation by a less invasive osteotome technique.

Sinus augmentation by osteotome technique

    Sinus augmentation can be performed by a less invasive osteotome technique.

This  technique is performed when the sinus floor that needs to be lifted is less than 4 mm. It is performed by flapping back gum tissue and making a socket in the bone within 1–2 mm short of the sinus membrane. With the use of osteotomes, the floor of the sinus is then lifted by tapping the sinus floor . The amount of augmentation achieved with the osteotome technique is usually less than what can be achieved with the lateral window technique. At the time of the sinus lift procedure, a dental implant is placed in the socket formed and left to integrate with bone. Bone integration generally lasts 4 to 8 months. The aim of this procedure is to stimulate bone growth and form a thicker sinus floor  to support dental implants for teeth replacement. Sinus shape and dimensions significantly influence new bone formation after transcrestal sinus floor elevation., The regeneration of a substantial amount of new bone is a predictable outcome only in narrow sinus cavities with this technique. Bucco- palatal sinus width should be regarded as a crucial parameter when choosing sinus floor elevation with transcrestal approach as a treatment option  during presurgical planning.
