Abstract

Introduction: Maxillary sinus augmentation and placement of dental implants is a well-established technique for functional and esthetic rehabilitation of partially or completely edentulous patients with severe maxillary atrophy. This study aimed to investigate dimensional changes of xenogarfts + allografts used for maxillary sinus augmentation in three directions and aspects of height, length and thickness by six months after sinus augmentation.
Materials and Methods: A total of 12 patients who underwent maxillary sinus augmentation by the approach of lateral window open sinus lift in Tehran university of medical sciences, and by application of xenografts + allografts were radiologically followed up and sequences of CBCT (Cone beam computed tomography) images taken immediately after graft placement and six months later. Data analyzed with Paired T-test in the 0.05 level of significance.
Results: The calculated mean resorption in aspects of height, length and thickness of grafted materials after six months was  2.99, 2, 37 and 1, 72 mm. with SD of 2.64-1.41 and 1.95.
Conclusion: In compared results of our study and other similar articles, it considered that directional changes of xenografts + allografts by six months after graft placement is mild to moderate, but it provides a reasonable density of new bone formation before implant placement.
