Radiographic Bone Volume Alteration After Jaw Cyst Enucleation With Different Bone Grafts

For decades, implantology has attracted extensive interest for restoration in patients with the defect of dentition. It has emerged as a very established prosthetic with a 5-year survival rate of 96% . However, defect of dentition resulted from jaw cyst remains an ongoing challenge for subsequent implantation treatment. Since it presents as a larger bone lesion than normal teeth extraction sockets and bone quality and quantity in teeth missing area can significantly impact dental implant failure rates . Jaw cysts are one of the most common diseases occurring in the oral and maxillofacial area, and often cause destructive bone lesions followed by specific clinical features, such as located pain, swelling and loosen teeth. Over the years, enucleation of jaw bone cysts has been the standard method of management of jaw cysts because its conservational protocol to remove the lesion thoroughly and reserve important structures and functions. Unfortunately, management of the residual bony cavity remains as a huge dilemma whether to filing the defect with additional material. Clot formation in the first instance is the conventional option for residual cavity recovery. Iodoform sponges are traditionally used in cysts as stuffing material for inflammation preventative purpose, however, it cannot help with the following bone formation. Without any bone filling material, researches revealed that spontaneous bone healing index can be from 25.85% to 76% and from 43.46% to 81.03% after 6 and 12 months post-operative respectively. These ranged results indicated that spontaneous bone healing is not efficient enough especially for patients with the extraction of relevant teeth who may process a subsequent surgery for implantation. As an alternative to this, bone graft material in the surgery has gained increasing attention. Autogenous bone, artificial bone substitutes and mix of them are widely applied to achieve higher bone regeneration. Thereby an alternative surgical procedure sho
