简要总结
Ultrasound activated pins have been used for the promotion of bone healing in combination with biodegradable membranes during bone grafting procedures. In the jaws, these pins have been successfully tested for both maxillary and mandibular ridge augmentaton. However, the usefulness of these pins in maxillary sinus lift procedures has not been tested. This study aims to use a bilateral split mouth design to compare the bone formation, healing and post-operative complications after the use of ultrasonic guided pins in a lateral window maxillary sinus augmentation procedure in comparison to lateral window maxillary sinus augmentation procedure procedure performed without the use of these pins.
详细描述
The study proposes to use a prospective split mouth crossover randomized control trial design to study the success of implant placement in cases with sinus lift procedures performed using the Sonic Weld® (KLS-Martin GmbH , Mulheim, Germany) ultrasound guided bone welding system with a membrane (Resorb X Membrane) on one side, and placement of Biomend collagen membrane to stabilize the graft
Patient selection:
20 patients requiring bilateral maxillary sinus lift procedure (40 procedures) will be selected from the patients reporting for implant placement to both the Riyadh Colleges of Dentistry and Pharmacy and the Riyadh Dental Center, King Saud Medical City.
Graft Placement:
Each patient will receive both the pin stabilized and the conventional graft placement procedures with standardized allografts (Purus® Cancellous Allograft?) on both sides of the maxilla. The grafts will be placed using the lateral window technique. The patients will be randomly assigned into either those who receive the pin first (Group A) or those who receive the conventional technique (using collagen membranes) first (Group B). The patients will have a one week gap between the sinus lift on the right and left sides.

Ultrasonic Pins
Lateral Window Technique Augmentation for Maxillary Sinus with the use of Ultrasound activated resorbable poly-D-L-lactide pins for the stabilization of the Purus® Cancellous Allograft, and Resorb X Membrane.Cone Beam CT image of the sinus will be taken to evaluate the bone formation. Trephine Biopsy will be performed after 1 year, at the time of placement of implant to check the quality of bone formed.
