(Comparative Study of Piezotome Intra-Lift and Osteotome Techniques in Closed Maxillary Sinus Lifting with Simultaneous Implant Placement by Radiographic Evaluation (Randomized Clinical Trial

Abstract

Endosseous dental implants are an excellent solution for prosthetic reconstruction in partially or completely edentulous patients. But as any treatment modality there are many limitations for dental implants, one of them is decreasing in the vertical and horizontal bone dimensions in the maxillary arch especially in the posterior region. This is occurred due to alveolar bone atrophy and maxillary sinus pneumatization after tooth loss. In addition, poor bone quality of maxilla which composed of fine trabeculae with little or no cortical crest, making it the least dense bone of the body. These limitations can prevent placement of dental implants of sufficient length leading to unsuccessful prosthesis loading, ended by implant failure.
