Mandibular Reconstruction:

 Surgical reconstruction of mandibular bone defects is a routine technique for rehabilitation of patients with deformities because of trauma, contamination or tumor resection. The mandible plays a main function in masticatory and phonetic functions, supporting the tooth and defining the contour of the decrease 0.33 of the face. Therefore, mandibular discontinuity produces extreme cosmetic and functional deformities, including lack of support for suprahyoid muscle tissues and subsequent airway reduction. Reconstruction of these extreme defects is mandatory for restoring the patient’s pleasant of life.

Surgical strategies have improved considerably in the closing decade, however reconstruction of huge bone defects of the mandible nevertheless pose an exquisite challenge in maxillofacial rehabilitation. Several things may be achieved to optimize the surgical operation; the usage of prototyping modeling for instance provides a better evaluation of the bone defect and pre-contouring of the fixation plates, lowering working time. The preference of the maximum suitable titanium plate gadget is critical to the fulfillment of the method. Mandibular defects with lack of continuity require extra robust (load bearing) structures supporting mandibular characteristic. Many studies take into account the usage of plates and screws brief treatment due to the big range of headaches including fracture of plates and screws, plate exposure and contamination. Thus, the use of grafts both within the first operation and in a two-stage method ensures an extra predictable result.

Bone grafts are extensively utilized in reconstructive surgical operation of the mandible. Incorporation of the bone graft restores continuity, shape, and power of the jaw to near regular characteristic. Installation of dental implants in the grafted regions is essential to repair masticatory characteristic and preserve bone graft volume. Autogenous bone is the exceptional desire for major reconstructions due to lack of rejection, and the presence of feasible osteogenic cells that increase bone formation and incorporation at the graft site. The use of a vascularized graft is a superb preference as it will increase the fulfillment of the treatment. However, this technique isn't to be had in all scientific centers. Autogenous loose bone (non-vascularized) is still the maximum used graft, even in principal reconstructions.
