Intraoral Bone Grafts

Bone grafting is one of the commonest practice in orthopaedics, surgical oncology & implant dentistry.bone grafts are used for non-union, mal-union, trauma/ fracture, filling defect due to bony cystor tumor ,reconstructive surgery , implant augumentation. extra oral bone grafts are gold standard . but intraoral bone grafts are now emerging alternatives as its close proximity to recipient site & comparatively less mortality & morbidity rates.this book will explore maxillofacial bone grafts science. this book is helpful to dental students, maxillofacial surgeons, implantologist, prsthodontist in learning science of bone grafting.

Vascularized Bone

Vascularized bone grafts (VBGs) are widely employed to reconstruct upper extremity bone defects. Conventional bone grafting is generally used to treat defects smaller than 5–6 cm, when tissue vascularization is adequate and there is no infection risk. Vascularized fibular grafts (VFGs) are mainly used in the humerus, radius or ulna in cases of persistent non-union where traditional bone grafting has failed or for bone defects larger than 6 cm. Furthermore, VFGs are considered to be the standard treatment for large bone defects located in the radius, ulna and humerus and enable the reconstruction of soft-tissue loss, as VFGs can be harvested as osteocutaneous flaps. VBGs enable one-stage surgical reconstruction and are highly infection-resistant because of their autonomous vascularization. A vascularized medial femoral condyle (VFMC) free flap can be used to treat small defects and non-unions in the upper extremity. Relative contraindications to these procedures are diabetes, immunosuppression, chronic infections, alcohol, tobacco, drug abuse and obesity. The aim of our study was to illustrate the use of VFGs to treat large post-traumatic bone defects and osteomyelitis located in the upper extremity. Moreover, the use of VFMC autografts is presented.

Grafting Technique

Autologous bone grafts (BGs) remain the reference grafting technique in various clinical contexts of bone grafting procedures despite their numerous peri- and post-operative limitations. The use of allogeneic bone is a viable option for overcoming these limitations, as it is reliable and it has been widely utilized in various forms for decades. However, the lack of versatility of conventional allogeneic BGs (e.g., blocks, powders) limits their potential for use with irregular or hard-to-reach bone defects. In this context, a ready- and easy-to-use partially demineralized allogeneic BG in a paste form has been developed, with the aim of facilitating such bone grafting procedures. The regenerative properties of this bone paste (BP) was assessed and compared to that of a syngeneic BG in a pre-clinical model of intramembranous bone healing in critical size defects in rat calvaria. The microcomputed tridimensional quantifications and the histological observations at 7 weeks after the implantation revealed that the in vivo bone regeneration of critical-size defects (CSDs) filled with the BP was similar to syngeneic bone grafts (BGs). Thus, this ready-to-use, injectable, and moldable partially demineralized allogeneic BP, displaying equivalent bone healing capacity than the “gold standard,” may be of particular clinical relevance in the context of oral and maxillofacial bone reconstructions.

Objective: To determine the incidence and risk factors of recipient surgical site infection (RSSI) after oral and maxillofacial reconstruction with vascularized fibular bone grafts (VFBG).Material and Methods: This retrospective study was performed in patients who underwent oral and maxillofacial reconstructive surgery, with VFBG, at the Dental Hospital, Faculty of Dentistry, Prince of Songkla University. Demographic, preoperative, intraoperative and postoperative data were recorded. Any infection at the recipient site occurring within 30 days post-operatively, by criteria from the Center of Disease Control, was defined as RSSI. Statistical analysis was performed by chi-square test, Student's t-test and Pearson’s correlation coefficient with statistical significance was set at 0.05.Results: There were twenty-one patients who met the eligibility criteria. The incidence of RSSI after oral and maxillofacial reconstruction with VFBG was 47.6% (10/21 patients), and the success rate of VFBG was 95.2%. American Society of Anesthetics (ASA) physical status class II and oral contamination were significant risk factors for RSSI (p-value=0.004 and p-value=0.031, respectively). Length of hospital stay was significantly higher in the RSSI group (p-value<0.001).Conclusion: The incidence of RSSI after oral and maxillofacial reconstruction with VFBG was high, and ASA physical status class II and oral contamination were significant risk factors for RSSI.

Introduction of dental implants and more concern in patients about esthetics after loss of natural teeth increases the demand of bone grafts. Various types of bone grafts as allografts, xenografts and autografts are used all with their own pros and cons. Bone grafts are more likely to succeed when the conditions at the recipient site are favourable and certain requirements are fulfilled. This review explores the use of various bone grafts in implant dentistry.

<p class="abstract"><strong>Background:</strong> Humeral shaft nonunions are frequently seen in Orthopaedic practice. Osteosynthesis with bone grafting is the treatment of choice. Locking compression plate (LCP) is the latest implant used in treating them. We retrospectively evaluated the outcome of use of LCP in humeral shaft non-union resulted by both conservative management and following failed internal fixations.</p><p class="abstract"><strong>Methods:</strong> Eighteen patients with nonunion of humeral shaft in which ten were treated by traditional bone setters and eight followed by failed internal fixation were included in these study. The mean duration of nonunion was 18.3 months (range 8-22).  The mean follow up period was 18 months (range 12-26). The mean age of patients was 44.4 years (range 22-60). All patients underwent osteosynthesis with LCP and autologoous cortico-cancellous iliac crest graft. The outcome measures include radiographic assessment of fracture union and preoperative and postoperative function using modified constant and murley scoring system.<strong></strong></p><p class="abstract"><strong>Results:</strong> All fractures united following osteosyntesis average time for union was15 weeks (range 10-24). We did not have any delayed union or non-union. The complications were superficial infection (n=1) and wound haematoma (n=1).Three patients with preoperative radial nerve palsy recovered at the end of four months. Functional evaluation using constant-murley score showed excellent result in 14, good in 3 and fair in 1. We did not have any poor results.</p><strong>Conclusions:</strong> LCP with cancellous bone grafting is a safe reliable option for all forms of humeral shaft nonunion. We recommend it.

OBJECTIVE: This study was proposed to estimate the effectiveness of different screening methods of the Burnout Syndrome among dental students. MATERIAL AND METHOD: The Burnout Syndrome assessment was performed using the Oldenburg Inventory-Student survey (OLBI-SS) and the Copenhagen Inventory-Student survey (CBI‑SS). The Maslach Burnout Inventory-Student survey (MBI-SS) was used as the gold standard. The psychometric properties of the instruments were measured. The second-order hierarchical model was estimated to calculate the overall scores for OLBI-SS and CBI-SS, and ROC curves were constructed and the areas were estimated (AUROC). RESULT: A total of 235 undergraduate students participated in this study. The instruments showed an adequate reliability and validity; however three questions had to be removed from OLBI-SS and one from CBI-SS. The Exhaustion dimension of OLBI-SS, and Personal Burnout and Study related Burnout of CBI-SS presented a good discriminating capacity. CONCLUSION: CBI-SS showed higher discriminating capacity, than OLBI-SS, to identify the Burnout Syndrome (DAUROC=.172 [.103-.240]; p<.05).
