Reconstruction of the posterior maxilla using cerabone® plus – A case report
Original title: Socket preservation, sinus lift and lateral augmentation by using natural bovine bone substitute with hyaluronate Zafiropoulos, G.; Trajkovski, B. Int J Dent Biomat Res 2023, 1, 1-6. https://ijdbr.com/index.php/ijdbr/article/view/12
The patient presented with partial edentulism and pain in the in the posterior upper jaw. At this time point the region was supplied with a partial denture temporarily fixed on the teeth #13, #23, #27 and #28.
Detailed diagnosis of the concerning area revealed advanced horizontal bone atrophy in the region #24-25, vertical bone loss in region #26, and signs of chronic sinusitis. Tooth #27 was found avital with advanced root caries. Tooth #28 presented with occlusal caries.
Two-stage bone augmentation for implant placement with three implants in positions #24, #25 and #26 was planned.
Following removal of the denture and teeth extraction a lateral sinus window was created. Then socket preservation of the tooth #27, as well as sinus augmentation with additional lateral augmentation in the area #24-25 was performed using cerabone® plus. The augmented area was covered with Jason® membrane. Tooth #28 was temporarily saved and used as an abutment of the removal temporary restoration.
Implants were placed six months post-augmentation. Four months later, the implants were uncovered and loaded by use of system specific customized abutments and metal ceramic fixed partial denture.
RESULTS & CONCLUSION
Sound graft integration into newly formed bone
Horizontal bone increase from 2.25 mm to 7.67 mm
Increase in bone volume allowed correct placement of dental implants
Implants were completely integrated into the regenerated bone
Satisfactory aesthetics by the end of the treatment
