Surgical Procedure
Two grams of Amoxicillin and 600mg Ibuprofen were given 1 hour before surgery. Chlorhexidine mouth rinse was used beforehand. A crestal incision with a full thickness flap was performed. The osteotomy was prepared to less than 1 mm from the sinus floor. An Osteotome has been used to gently fracture the sinus floor. The Putty was inserted resulting in a hydraulic pressure onto the Schneiderian membrane, after which the short implants 5mm(w) x 5 or 6 mm(l)2 were placed. The implant gently pushes the putty into the sinus area resulting in lifting of the Schneiderian membrane.

Flaps are repositioned in a tension free manner and then are sutured into place. They were removed 10-14 days after treatment. Implants were allowed to heal for at least 4 months before crown placement. None of the patients had any pain, swelling or other complaints after the surgery.
