The posterior maxilla often presents specific problems for placement of dental implants. Frequently poor bone quality with inadequate bone volume has rendered long-term success rates for implants1). To overcome this situation, usually sinus floor elevation was carried out through the lateral approach technique or crestal approach, so called, osteotome method. The osteotome technique, first described in 1994, has been known for the primary advantage of being less invasive than lateral window approach2). However, osteotome technique comes with the magnitude of forces and the amount of heat. This malleting osteotome technique has several post operative complications such as unpleasant discomfort and inner auditory organ damage once in a while3). Also the possibility of damage on the sinus membrane still remains.
