Abstract: Introduction It is essential for the dental implantologist to be aware of the time-dependent volume changes that could occur in the augmentation material. Should the implant placement stage be delayed in time, the dental clinician must select the appropriate bone grafting material for the specific case. Materials and methods 35 patients were eligible for inclusion, divided into 4 groups, who had a planned maxillary sinus floor augmentation procedure with different bone replacement materials Group 1 (10 patients) - Bone Ceramic (a synthetic biphasic calcium phosphate material, consisting of hydroxyapatite and -tricalciumphosphatein a ratio of 6040). Group 2 (10 patients) Cerabone (Xenogenic bone material from the mineral phase of bovine bone). Group 3 (10 patients) - Maxresorb inject (Calcium phosphate paste, composed of 80 % nano-hydroxyapatite aquagel and 20 % biphasic calcium phosphate granules). Group 4 (5 patients) - Collagen fleece absorbedin venous blood. Results The various bone grafting materials applieddemonstrated differentvolume loss over time following a maxillary sinus floor augmentation procedure. The least volume loss over time was found in the application of Xenogenic bovine hydroxyapatite material (XBHM), and most volume contraction was observed in the use of Biphasic calcium phosphate paste material (BCPPM). ConclusionsIn maxillary sinus floor augmentation procedures the application of Xenogenic bone material from the mineral phase of bovine bone as an augmentation material has proven to maintain its volume the longest in comparison with other bone grafting materials.
