First Clinical Case Report of a Xenograft–Allograft Combination for Alveolar Ridge Augmentation Using a Bovine Bone Substitute Material with Hyaluronate (Cerabone^® Plus) Combined with Allogeneic Bone Granules (Maxgraft^®)

Abstract

Background: A patient had lost the first left maxillary incisor in the esthetic zone. Methods: The defect in the alveolar ridge was reconstructed for an implant-supported restoration using a new xenogeneic bone substitute containing hyaluronate, which was used in combination with allogeneic bone granules. Results: After three years of follow-up, the dental implant was stable and showed no signs of infection. Conclusions: This is the first case report with a long-term follow-up time of three years of a successful clinical application of a xenograft–allograft combination (cerabone® plus combined with maxgraft®) for alveolar ridge augmentation before dental implantation. Cerabone® plus offers volume stability, provides reliable and efficient structural support of the oral soft tissues in the augmented region (particularly crucial in the aesthetic zone), and preserves the alveolar ridge shape.
