“…The exploration of corresponding changes within cortical bone structures of the human alveolar region or other parts of the craniofacial skeleton has been limited. Osteopenic effects with functional loss and aging have been reported (Bras et al, 1983), and in the mandible these effects often contribute to a larger amount of malunion or nonunion of fractures in edentulous human patients (Buchbinder, 1993). Likewise, these effects suggest that changes in craniofacial form, elastic properties, strength, and density are often concurrent.…”

Skeletal adaptations to reduced function are an important source of skeletal variation and may be indicative of environmental pressures that lead to evolutionary changes. Humans serve as a model animal to investigate the effects of loss of craniofacial function through edentulation. In the human maxilla, it is known that edentulation leads to significant changes in skeletal structure such as residual ridge resorption and loss of cortical thickness. However, little is known about changes in bone tissue structure and material properties, which are also important for understanding skeletal mechanics but are often ignored. The aims of this study were to determine cortical material properties in edentulous crania and to evaluate differences with dentate crania and thus examine the effects of loss of function on craniofacial structure. Cortical bone samples from fifteen edentulous human skulls were measured for thickness and density. Elastic properties and directions of maximum stiffness were determined by using ultrasonic techniques. These data were compared to those from dentate crania reported in a previous investigation. Cortical bone from all regions of the facial skeleton of edentulous individuals is thinner than in dentate skulls. Elastic and shear moduli, and density are similar or greater in the zygoma and cranial vault of edentulous individuals, while these properties are less in the maxilla. Most cortical bone, especially in edentulous maxillae, has reduced directional orientation. The loss of significant occlusal loads following edentulation may contribute to the change in material properties and the loss of orientation over time during the normal process of bone remodeling. These results suggest that area-specific cortical microstructural changes accompany bone resorption following edentulation. They also suggest that functional forces are important for maintaining bone mass throughout the craniofacial skeleton, even in areas such as the browridges, which have been thought to be little affected by function, because of low in vivo strains found there in several primate studies.

“…Treatment of fractures in older patients with bone atrophy is characterized by high morbidity due to local and general factors (Ellis and Price, 2008). In fact, serious complications are common, especially in patients with atrophy classes II and III, such as non-union or fracture of hardware, the incidence of which has been reported to range between 4% and 20% (Luhr et al, 1996;Bruce and Strachan, 1976;Buchbinder, 1993;Eyrich et al, 1997;Iatrou et al, 1998;Kunz et al, 2001) and is probably linked to the bone height in the area of fractures (Bruce and Ellis, 1993;Wittwer et al, 2006).…”

Elderly patients management Bone marrow aspirate cells Min-invasive surgical approach a b s t r a c t Purpose: The treatment of fractures involves addressing the biology of fracture repair and the mechanical stability of fracture fixation. Traditionally it has included the addition of bone graft to enhance healing. New advances in the understanding of the cellular and molecular mechanisms of fracture repair have led to the use of growth factors to accelerate bone healing. This study aimed to assess the advantages of autologous stem cell use for atrophic mandibular fracture treatment in comparison to standard technique. Materials and methods: A total of 35 patients (14 male and 21 female) were treated for fractures of atrophic mandibles between January 2011 and December 2014. Surgical technique provided miniinvasive open reduction with or without immediate homologous bone graft, while selected patients received autologous bone marrow aspirate cell grafts in addition to the standard treatment. Demographic data and details of treatment and outcomes were recorded. Results: Patients were categorized according to the use of autologous stem cells, leaving 17 patients treated with standard technique and autologous stem cells (Group A) and 18 treated with standard osteosynthesis only (Group B). Of the 35 patients, 26 had bilateral fractures; most patients had significant medical co-morbidities. Immediate bone graft was used in 37.1% of patients (7 in group A and 6 in group B). Complications occurred in 5 patients (14.3%). Two patients in group B (11.1%) showed non-union of the fracture. One patient in group A (5.8%) and one patient in group B (5.5%) showed wound dehiscence and were treated conservatively; one patient in group B had a local infection (5.5%), one out of 35 (2.8%), that was managed by prolonged antibiotic treatment. Conclusions: Despite the advanced age and medical co-morbidities of the vast majority of patients, miniinvasive open approach with autologous bone graft ensures a fast and excellent recovery. Moreover, the management of atrophic mandibular fractures by bone marrow aspirate cells is a safe and useful procedure which has a lower complication rate when compared to standard technique.

Maxillofacial injuries are most commonly associated with falls, motor and vehicle accidents, sportsrelated trauma, and interpersonal violence. The complexity of mandibular condyle region and its anatomic proximity to other craniofacial structures complicate diagnosis and treatment. Thus, treatment approaches of mandibular condyle fracture are still controversial. In the literature, different success rates are reported about observation versus treatment, closed reduction versus open reduction and fixation methods. In the present article, controversial issues related to mandibular condyle fractures were reviewed under the light of current literature. In conclusion, the simplest way that can be done with the least risk of complication should be chosen during treatment planning. In addition, current adjunctive treatment methods accelerating healing of fracture should be considered. Key words: Open reduction, closed reduction, fracture, mandibular condyle, temporomandibular joint. ÖZETÇene-yüz yaralanmaları en sık duşmeler, motorlu taşıt kazaları, sporla ilgili travma ve bireyler arası şiddetle ilişkilendirilir. Mandibular kondil bölgesinin karmaşıklığı ve bölgenin diğer kraniyofasiyal yapılara anatomik yakınlığı tanı ve tedaviyi zorlaştırmaktadır. Bu sebeple mandibular kondil kırıklarının tedavi yaklaşımları halen tartışmalıdır. Literatürde gözleme karşı tedavi, kapalı reduksiyona karşı açık reduksiyon ve fiksasyon metodlarıyla ilgili farklı başarı oranları bildirilmektedir. Bu makalede, mandibular kondil kırıkları ile ilgili tartışmalı hususlar güncel literatür ışığı altında derlenmiştir. Sonuç olarak; tedavi planlamasında en az komplikasyon riskiyle yapılabilecek en basit yol seçilmelidir. Ek olarak; kırık iyileşmesini hızlandıran güncel destekleyici tedavi yöntemleri göz önünde bulundurulmalıdır.
