Abstract

Aim This in vivo study aims to compare the quantity and quality of bone formation around dental implants inserted following Tatum’s approach with placement of Concentrated Growth Factors (CGF). Materials and methods This prospective study involved 20 patients requiring maxillary sinus augmentation for missing maxillary first molars. These patients were randomly divided into two groups: one in which sinus augmentation was followed by placement of CGF and simultaneous implant placement and the other in which no grafting material was used also followed by immediate implant placement. Radiographic assessment was carried out six months postoperatively using Cone Beam Computed Tomography (CBCT) to assess the quantity and quality of the new bone formed. Results CBCT analysis showed a mean bone gain of 3.193 mm in subjects in the test group and 4.47 mm in the control group. Also, a statistically significant difference was noted in bone quality in the test group when compared to controls. Conclusion This study indicates that direct sinus augmentation with CGF and immediate implant placement is a viable treatment option for the atrophic posterior maxilla. However, further studies are required to validate the quantity of bone formation preferably using Computed Tomography (CT).
