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.

Objective: Comparison between bovine-derived demineralized bone matrix (DMBM) and iliac crest graft over long term for secondary alveolar bone grafting (SABG) in patients with unilateral cleft lip and palate (UCLP) in terms of radiological and clinical outcomes. Design: Prospective, randomized, parallel groups, double-blind, controlled trial. Setting: Unit of Oral and Maxillofacial Surgery, Oral Health Science Centre, Postgraduate Institute of Medical Education & Research, Chandigarh. Participants: Twenty patients with UCLP. Interventions: Patients were allocated into group I (Iliac crest bone graft) and group II (DMBM) for SABG. Outcomes were assessed at 2 weeks, 6 months, and then after mean follow-up period of 63 months. Outcomes Measures: Volumetric analysis of the grafted bone in the alveolar cleft site was done through cone beam computed tomography using Cavalieri principle and modified assessment tool. Clinical assessment was performed in terms of pain, swelling, duration of hospital stay, cost of surgery, alar base symmetry, and donor site morbidity associated with iliac crest harvesting. Results: Volumetric analysis through Cavalieri principle revealed comparable bone uptake at follow-up of 6 months between group I (70%) and group II (69%). Modified assessment tool showed no significant difference between horizontal and vertical bone scores over short- and long-term follow-up. In group II, there was higher cost of surgery, but no donor site morbidity unlike group I. Conclusions: Demineralized bone matrix proved analogous to iliac crest bone graft as per volumetric analysis over shorter period. However, although statistically insignificant, net bone volume achieved was lower than the iliac crest graft at longer follow-up.

Extraction of the natural tooth may be a prelude to implant placement. This may be done using an immediate placement protocol or require a delayed approach depending on multiple factors that include; residual infection related to the failed tooth being extracted, availability of bone to stabilize the implant at placement or soft tissue issues. Socket preservation is recommended when the delayed approach is selected to create an osseous bed that can accommodate the implant that is planned. This also helps preserve what crestal bone remains following the extraction that may resorb in the absence of socket preservation during the extraction socket healing phase. The use of osseous graft materials and guided bone-regeneration has demonstrated enhancement of socket healing by potentially modifying the resorption process, yielding preservation of the crestal bone while limiting resorption potential during healing. Various graft materials have been reported including, allografts, xenografts, non-biologics and synthetics. Calcium sulfate as a graft material has been used for many decades in maxillofacial surgeries, plastic surgery, oncologic and orthopedics in the treatment of osseous voids, traumatic or inflammatory bone deficiencies. This article will review a case using biphasic calcium sulfate with a delayed implant protocol and the histology demonstrating conversion of the graft material to host bone following healing.

This study is aimed at assessing the dimensional alterations occurring in the alveolar bone after premolar extraction in dogs with histomorphometric and histological analysis. After atraumatic premolar extraction, tooth-derived bone graft material was grafted in the extraction socket of the premolar region in the lower jaws of six dogs in two experimental groups. In the second experimental group, BM-MSCs were added together with the graft. The control was left untreated on the opposite side. After twelve weeks, all six animals were sacrificed. Differences in alveolar bone height crests lingually and buccally, and alveolar bone width at 1, 3, and 5 mm infracrestally, were examined. Histologic study revealed osteoconductive properties of tooth biomaterial. A statistically significant difference was detected between the test and control groups. In the test groups, a reduced loss of vertical and horizontal alveolar bone dimensions compared with the control group was observed. Tooth bone graft material may be considered useful for alveolar ridge preservation after tooth extraction, as it could limit the natural bone resorption process.

Object Posterolateral spinal fusions are performed to treat different spinal disorders. Autograft continues to be the gold standard; it is, however, associated with donor site morbidity and limited sources. Allograft has been used, but has been reported to result in lower fusion rates. Demineralized bone matrix (DBM) has also been used and reportedly increases the fusion rate in a variety of critical defect models. Different forms of DBM are available, not all have been independently studied. To evaluate the effect of a xenogenic DBM added to allograft on the fusion rate of posterolateral lumbar spine arthrodesis the authors designed an experimental study comparing posterolateral fusion rate using autograft, allograft, and allograft plus a xenogenic DBM in a validated animal model. Methods A bilateral, 1-level (L4–5) intertransverse process fusion was performed in 45 male New Zealand rabbits. Iliac crest bone graft was harvested bilaterally from each rabbit. The rabbits were randomly assigned to 3 groups: Group I, Autograft, 15 rabbits; Group II, Allograft, 15 rabbits; and Group III, Allograft plus DBM in a paste form (Dynagraft). The animals were killed 8 weeks after surgery. Fusion was assessed radiographically and by manual palpation by 2 independent observers. The results were analyzed using the Fisher exact test and chi-square test. Results The fusion rate was 46.6% (7 of 15 rabbits) in the autograft group, 33.3% (5 of 15 rabbits) in the allograft group, and 33.3% (5 of 15 rabbits) in the allograft plus DBM group (p > 0.05). Conclusions Autograft produced a higher fusion rate than allograft in this spinal fusion rabbit model, but the difference was not statistically significant. Allograft plus xenogenic DBM showed the same fusion rate as allograft alone.

ABSTRACT Introduction The preservation of bone volume immediately after tooth removal is necessary to optimize the success of implant placement in terms of esthetics and function. The objectives of this study were to compare the ability of Choukroun's platelet-rich fibrin (PRF) versus CollaPlug (Zimmer) in maintaining the buccal bone height of sockets following extractions in patients. Materials and methods Twenty patients who required tooth extraction and implant placement were enrolled in this study. The patients were randomly divided into two groups. They are group I PRF group and group II CollaPlug group. The vertical buccal crestal bone heights were measured immediately after extraction and 4 months postextraction and implants were placed. Results The buccal crestal bone level in the CollaPlug group had a baseline mean of 4.67 ± 0.54 and a postmean of 6.98 ± 0.60, whereas in the PRF group baseline mean was 5.43 ± 0.47 and postmean was 6.93 ± 0.55. The bone resorption was found in both the groups (2.31 mm for CollaPlug and 1.5 mm for PRF), in agreement with previous studies. However, there was increased bone loss in CollaPlug group compared with PRF group, which was found statistically significant. Conclusion In conclusion, within the limits of the present study, the two tested socket preservation materials seem to be effective in the treatment of extraction sockets, even though the design of the study did not allow us to evaluate to what extent the clinical improvement could be attributed to the PRF per se, since a negative control was not included in this investigation. However, preparation of PRF is not very cumbersome and inexpensive, which makes it a better socket preservation material than CollaPlug. How to cite this article Madhan G, Singh M.

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.
