Mesenchymal Stem Cell Approach for Maxillary Sinus Grafting

Autogenous bone has long been a gold standard grafting material for bone defects. It possesses osteogenic, osteoinductive and osteoconductive properties ideal for bone healing. However, the need of a donor site surgery and related morbidities remain a major concern to the patients. Therefore, bone substitutes have been recognised to be alternatives to autogenous bone. Since they are cell-free materials providing at their best only osteoconductive property, the concept of introducing mesenchymal stromal cells (MSCs) creates a lot of interest. This MSCs strategy can potentially contribute all the three osteo-regenerative properties similar to autogenous bone graft. The MSCs are commonly harvested by aspiration methods from the posterior hip of the same host. The cell number can be amplified by culturing in the laboratory for a period of time or concentrated using a centrifuge and dedicated systems to achieve sufficient quantity for immediate transplantation. Its application in oral and maxillofacial regions, particularly on maxillary augmentation for dental implant rehabilitation, has been researched with promising clinical results

Changes in the faces and smiles of patients with dentofacial deformities

In recent years, new materials and more versatile techniques have made it possible for increasingly complex dentofacial deformities to be treated by multidisciplinary teams, with maxillofacial surgeons and orthodontists as the core team members. This lecture will demonstrate the treatment of these challenging cases. Through teamwork, maxillofacial surgeons and orthodontists can bring back smiles to these patients.postprin

The applications of stereolithography in facial reconstructive surgery

The development of rapid prototyping has evolved from the crude milled models to the laser polymerised stereolithographic models of excellent accuracy. The technology was advanced further with the recent introduction of fused deposition modelling and the 3-dimensional ink-jet printing technique in stereo-model fabrication. The concept of using a 3-dimensional model in planning the operation has amazed the maxillofacial surgeons since its first application in grafting a skull defect in 1995. It was followed by many bright ideas of applications in the field of facial reconstructive surgery. The stereo-model may assist in the diagnosis of facial fractures, joint ankylosis and even impacted teeth. The surgery can be simulated prior to the operation of complex craniofacial syndromes, facial asymmetry and distraction osteogenesis. The stereo-model can be used for preparation of reconstructive plate or joint prosthesis. It has an enormous value as an educational teaching and patient information tool for obtaining the consent for surgery. The aims of the paper are to present the modern manufacturing methods of the stereo-model and to illustrate the clinical applications of the stereomodel in facial reconstruction.published_or_final_versio

Surgical reconstruction of the jaws after ablative surgery

Ablative surgery of the jaws may be necessary when malignant disease or destructive benign disease occurs. Surgical reconstruction needs to include the restoration of masticatory function so that the quality of life after operation is optimal. This paper describes some current concepts in functional reconstruction after mandibulectomy and maxillectomy and includes case examples that illustrate bone-grafting procedures and occlusal rehabilitation by implant-borne restorations.published_or_final_versio
