Abstract
Introduction: In order to fulfill the optimum objectives of implant dentistry, there are numerous methods available for effective soft and hard tissue augmentation to present ideal bone volume and quality. The strategy is mostly determined by the severity of the defect and the particular procedures to be carried out for the implant or prosthetic rehabilitation; especially in the anterior esthetic zones.
Aim of the study: Assess horizontal alveolar ridge augmentation clinically and radiographically by using cone beam computed tomography (CBCT) after placing sticky bone covered by Concentrated Growth Factor Membrane (PRF) in anterior esthetic zone.
Materials and Methods: Ten patients presenting with Seibert Class I ridge classification (labio-palatal anterior maxillary residual alveolar width ranged from 3-4 mm) received horizontal augmentation using Sticky Bone covered by PRF membrane. Patients were post-operatively assessed for pain (using Visual Analogue Scale), edema, and any signs of inflammation or infection. CBCT scans were taken preoperatively, and after 3 and 6 months to assess the changes in horizontal bone quantity and bone density.
Results: Clinically, all patients showed normal soft tissue healing. Radiographically horizontal bone gain at 3 months postoperatively ranged from 2.13-3.39 mm with a mean ±S.D. of 2.86±0.38 m. At sixth month, bone gain ranged from 2.07-3.35 mm with a mean ±S.D. of 2.84±0.39 mm. At the third month, bone density ranged from 851.01-883.15 HU with a mean ± S.D. of 868.51±11.07 HU, At the sixth month, bone density ranged from 1013.72-1198.12 HU with a mean ± S.D. of 1096.36±54.44 HU. bone density at the sixth month was statistically significantly higher compared with bone density at the third month (D2 850-1250).
Conclusion: Based on the study result, horizontal ridge augmentation using sticky bone covered by PRF membrane is a simple technique and can increase the quality of the new bone and boost the rate bone formation.
