| Abstract | ||
| Background: Choosing augmentation equipment is a critical factor in maxillary sinus augmentation. The choice of one of these materials for sinus augmentation remains controversial. Purpose: The aim of this clinical study was to compare the biological performance of the new coral hydroxyapatite (CHA) graft material and the synthetic material made from tricalcium phosphate (b-TCP) in sinus augmentation. Materials and Methods: The study consisted of 20 patients (10 men and 10 women) who were edentulous or partially edentulous in the posterior maxilla and required the placement of implants. A total of (20) sinus transplants were performed in a single step using implant installation procedures. CHA was used in 10 patients and b-TCP in 10 patients. Results: An average increase in the height of the mineralized tissue of 7.1 ± 1.1 mm in the b-TCP group and 4.6 ± 1.17 mm in the CHA group was when comparing the preoperative CT scan with that after 9 Months. After the maxillary sinus augmentation procedure. The average percentage of the density of the transplanted area after 9 months, based on the initial alveolar ridge density at the implantation site, was 63.6 % and - 2.89 % for the b-TCP group and the CHA group (P < 0.001 and 0.373) respectively. Conclusion: Both graft materials showed successful biocompatibility and osteoconductivity in sinus augmentation. However, B-TCP appears to be more effective than CHA in osteoconduction. | ||
