Implant Placement in Left Maxilla With Closed Sinus Lift Using ABGuidedService

Dr. Ernest Reuveni & Dr. Gustavo Yatzkaier.
The patient is a healthy 53-year-old, and she does not smoke. The bone used is of animal origin.
This method of sinus lift was chosen to significantly reduce the risk of perforating the sinus membrane. The Safe system allows maximum elevation with minimal risk.
ABGuided allows the drill depth to be planned 1mm from the sinus floor. This can be difficult to measure using the CT alone, as the sinus floor is curved. The exact location can be found with the guide which is digitally produced from the planning in the 3D software. The entry into the sinus can then be completed using an osteotomy.
