Abstract

Bone loss after tooth extraction is inevitable, it can be horizontal, vertical bone loss or combination. Now a days, dental implants are emerging as a better treatment option for oral rehabilitation and become an integral part of dentistry ,thus availability of adequate bone volume in all 3-dimensions to stabilize implant is foremost requirement for successful treatment. Various methods have been used to augment the ridge bone volume which includes bone grafting along with guided bone regeneration, ridge split technique, sinus lift procedure and distraction osteogenesis. This case report presents aesthetic rehabilitation by implant retained prosthesis in upper anterior region with large defect by combining bone augmentation with ridge split technique to enable implant placement. Keywords: Dental implants, Ridge split technique, Bone augmentation, Bone grafting, and Implant retained prosthesis.

Abstract

Introduction: Dental implants are the most innovative and superior treatment in dentistry, and are widely used. However, the intended implant site may be inappropriate due to the poor bone quality or insufficient bone volume. When extensive loss of alveolar bone is encountered it presents a complex challenge for reconstruction. Numerous augumentation technique are used for alveolar reconstruction and to create sufficient bone volume for placement of endosseous implants. In order to accelerate healing of bone graft over the bony defect, numerous techniques utilizing platelet and fibrinogen concentrations have been introduced in the literature. Sticky bone provides stabilizationof bone graft in the defect, and therefore, accelerates tissue healing and minimizes bone loss during healing period. Due to formation of homogenous mass of bone graft particles, handling and adaptation of bone graft becomes easy. The use of sticky bone also avoids complex ridge augumentation procedures. Aim: The aim of this case report is to demonstrate the use of sticky bone and autologous PRF membrane in hard tissue regeneration and maintenance of volume of alveolar ridge to enable dental implant placement. Material and Methods: Ridge augmentation was done in defect using sticky bone formed by cera bone granules of particle size 0.5-1.0 mm and PRF membranes. Results: Sufficient bone volume was achieved through GBR as shown by comparing presurgical and post 3months CT and clinically it can be seen at second stage surgery done after 3 months. Conclusion: The result suggested that GBR with autologous PRF membranes is sufficient for augmentation of localised alveolar ridge defects with conjunction with sticky bone. Sticky bone provides stabilization of bone graft in defect and improves handling properties and PRF membranes act as barrier membrane as well as source of accelerated growth factor release. Keywords: Dental implant, Sticky bone, and Platelet rich fibrin (PRF) membrane.
