Sinus lifting is a common surgical intervention. A dentist or specialist with proper training such as an endodontist, periodontist, prosthodontist, or oral surgeon thickens the inadequate part of atrophic maxilla towards the sinus with the help of bone transplantation or bone expletive substance. This results in more volume for a better quality bone site for the implantation.

A sinus-lift procedure is performed  to augment bone mass in the top jaw (maxilla), which increases the likelihood of successful placement of dental implants. Bone from another part of the body, such as the iliac crest, or artificial bone grafting material is grafted into the bone (endosseous) below the floor of the maxillary sinus. In the upper jaw the amount of bone is reduced by the presence of the sinus.
