Demineralized Bone

An ideal bone graft material should have osteocondutive, osteroindurctive, and osteogenic features. Scientists and doctors have been trying to develop this kind of material for over one century. However, all the features of few materials used in clinic now have been qualified. Recently, COLLOSS, as the new generation bone graft material of demineralized bone matrix, almost achieved this height. The paper presents a general survey of COLLOSS including its extraction processes, biological characteristics, and application prospects.

Composite Bone

Demineralized bone matrix (DBM) is a decalcified allo/xenograft retaining collagen and noncollagenous proteins, which has been extensively used because of its osteoconductive and osteoinductive properties. Calcium sulfate (CaSO4, CS) is a synthetic bone substitute used in bone healing with biocompatible, nontoxic, bioabsorbable, osteoconductive, and good mechanical characteristics. This study aims to prepare a DBM/CS composite bone graft material in a moldable putty form without compromising the peculiar properties of DBM and CS. For this purpose, firstly, porcine femur was defatted using chloroform/methanol and extracted by acid for demineralization, then freeze-dried and milled/sieved to obtain DBM powder. Secondly, the α-form and β-form of calcium sulfate hemihydrate (CaSO4 •0.5H2O, CSH) were produced by heating gypsum (CaSO4 •2H2O). The morphology and particle sizes of α- and β-CSH were obtained by SEM, and their chemical properties were confirmed by EDS, FTIR and XRD. Furthermore, the DBM-based graft was mixed with α- or β-CSH at a ratio of 9:1, and glycerol/4% HPMC was added as a carrier to produce a putty. DBM/CSH putty possesses a low washout rate, good mechanical strength and biocompatibility. In conclusion, we believe that the moldable DBM/CSH composite putty developed in this study could be a promising substitute for the currently available bone grafts, and might have practical application in the orthopedics field as a potential bone void filler.

Introduction: Dental implant has proved to be a pioneer in prosthetic rehabilitation overcoming the disadvantage of a removable or a fixed partial denture. The aim of the study was to clinically and radiographically evaluate and compare changes of hard and soft tissues around the implants which will be placed in ridge preserved sites with implant placed in naturally healed extraction sites. Materials and Methods: In this study 10 Patients having tooth with hopeless prognosis requiring tooth extraction followed by implant placement were enrolled. These patients were randomly divided in to two groups. Group I: Socket preservation with demineralized bone matrix putty group. Group II: Naturally healed socket after extraction, followed by implant placement in both groups. Results: The results of the current study indicated that demineralisedbone matrix putty, when used in patients for dental augmentation in either mandibular or maxillary sites, resulted in replacement of the graft material with bone by as early as 4-6 months, there upon enabling implant placement and subsequent prosthetic reconstruction. Conclusion: Bucco lingual ridge width and width of keratinized gingiva can be preserved by ridge preservation after extraction. Short-term survival rates and clinical outcomes of both groups were similar and were comparable. Further clinical trials with longer duration follow up with larger sample size should be done to get more affirmative and conclusive results.
