ABSTRACT

Rehabilitation of the posterior edentulous maxilla presents maxillofacial surgeons with many challenges. Sinus floor elevation is considered the milestone in the implant dentistry; however, it is associated with numerous complications. To overcome the complications, CAS kit (Crestal Approach Sinus) has been used in the following study. Ten subjects we enrolled in this pilot study using the CAS kit. The study sought to investigate incidence of sinus membrane perforation, implant stability, marginal bone loss and the area of bone regeneration. Each patient experienced satisfactory results with minimal complications. The invention of the CAS kit has the potential to prove suitability in overcoming the complications and disadvantages of conventional sinus floor elevation techniques.
