Due to the recent advancements in implant dentistry, bone grafting is done in few clinical cases. Nevertheless, there isn’t a complete elimination of this surgical process. The clinical cases with reduced bone density, low bone volume or compromised quality of bone mostly warrant the placement of bone graft. Earlier, autogenous grafts were used in bone grafting. Then, these were replaced by xenografts. Most commonly, bovine bone grafts are used for guided tissue regeneration.
A proper technique for graft placement and a graft with excellent properties are essential for the successful outcome of the treatment procedure with bone grafting. The different types of bone grafts include autograft, allograft, xenograft, and alloplastic. This classification is based on the source of the bone grafting material. Alloplastic bone grafts are synthetically derived products that are used for bone grafting. The main advantage of using alloplastic material is that the chances of disease transmission are eliminated and also these types of graft have osteoconductive properties. Finding the ideal material for bone grafting has long been the target of the medical researchers and this led to the development of the synthetic bone. Since it is not derived from human or animal resource and is manufactured synthetically, it can be modified to get utmost advantages.
The advantages of Bongraft include:
- It is a synthetic product and so the risk of transmission of disease like HIV, HBV, etc. is eliminated.
- It is completely absorbed within 4-6 months.
- It has osteoconductive properties. The material is completely replaced by the trabecular bone.
- It acts as a physiologic space maintainer as it is well accepted by the biologic tissues and the chances of rejection of the graft material are almost nil.
- It is not radiopaque and so the formation of the new bone can be radiographically monitored.
- In some situations, the use of the membrane in guided bone regeneration procedures can be avoided.
- It is scientifically tested and costs less when compared to similar products in the market.
The co-polymers of polylactic acid and polyglycolic acid with different molecular weights have been used successfully in orthopaedics and oral and maxillofacial surgery. The advantage of this material available in 3 different forms i.e. gel, sponge and powder makes the use of this product possible in almost every type of bone defect.
Newly formed bone
The data in this table is the result when Bongraft was compared with other products like bioglass, bio-coral, DFDBA, and others . This study proves that Bongraft is an ideal physiologic bone grafting material .
The Bongraft can be used in gel, powder or sponge form and even either of these forms can be combined for getting the successful treatment outcome.
- The gel form can be effectively used in the sinus lifting procedure of the maxillary sinus with minimally invasive technique . It can be easily injected into the sinus cavity and it exerts a hydraulic pressure on the membrane and raises it effectively in the most atraumatic manner.
- Bongraft sponge can be used for the best results in the post-extraction sites .
Bongraft powder can also be combined with the gel and used in surgical situations. Also, the Bongraft gel can be used in diverse clinical scenarios like treatment of root fractures after endodontic treatment. The combination of the sponge and gel form can be done, especially in situations that eliminate the need of membrane for guided regeneration .
Thus, expertise of the surgeon and the choice of the material play an important role in bone grafting procedures. Bongraft is the ideal space maintainer with many favourable properties that can be used to achieve effective treatment outcomes in wide variety of surgical procedures.
