Long-term success of sinus augmentation using a synthetic alloplast: a 20 patients, 7 years clinical report.

An adverse architecture of the maxillary sinus is no longer a contraindication for implant placement. Grafting the sinus has become an accepted treatment modality. Techniques for lifting the sinuses are well documented and numerous articles have been published. The main difference between the multitude of articles seems to be the graft material used. After having used different grafts, with varying success, this article reflects the authors' impressions on one particular grafting material, a composite synthetic bone substitute. The objective of this clinical study was to evaluate the effectiveness, reliability and predictability of that synthetic graft material (Bioplant HTR). After treating 20 patients (22 sites, 56 implants), and after a follow-up period as long as 7 years, it was clinically and radiographically observed that achieved results are enhanced if this synthetic graft material is used and that its use enhances sinus augmentation outcome and predictability. It provides the patient with the benefits of implant-supported restorations in a simple, quick, cost-effective, predictable, and secure manner.
