Homeostasis is continuous process by which internal body system monitor and maintain constant internal environment. Blood is a connective tissue in fluid state closely connected to all tissues of the body. It has many roles including transport of nutrients, metabolic products, blood gases, thermal regulation hormone signaling system, heat conduction, immune response. Hemostasis is homeostasis of intravascular blood volume and is an important function of blood. It involves four major steps: vasoconstriction, platelet aggregation, coagulation and fibrinolysis [1]. The phase of vasoconstriction reduces the blood flow in preparation for platelet aggregation phase. However, the larger the size of the injured blood vessel the less possibility of vasoconstriction especially with high pressure.

Osseointegration can be defined as a direct connection, both structural and functional, between living bone and the surface of an artificial implant. Indeed, the word comes from the Greek term for 'bone' and 'to make whole'. In dentistry, once dental implants are placed, the body will react with osseointegration, enabling the implants to become a permanent part of the jaw. There are many benefits to this type of implant, compared with traditional tooth replacement options, not least that dental implants mimic the strength and functionality of a natural tooth. Dr Shuhei Tsuchiya is a researcher based in the Division of Oral and Maxillofacial Surgery at Nagoya University, Japan, who is interested in a range of areas, including regenerative medicine and the extracellular matrix. One of his key preoccupations, though, is shedding light on osseointegration. He and his team are working to unravel the mysteries of the mechanism.

The pathology of the oro-maxilo-facial territory comprises a vast chapter of diseases with primary or secondary infectious etiology, the mouth being the natural cavity of the organism with the most varied and variable flora of bacterial contamination. By the continuity solutions created by the mechanical act of mastication, decubitus of defective prosthetic works, local dento-periodontal infectious processes, but especially of dental or small-scale interventions, open gates and possibilities of penetration into the blood circulation of the microorganisms, which cause the transient bacteria. The study included 243 randomly selected patients, with the address of the Oral and Maxillofacial Surgery Clinic in the period 2016-2018. The inoculation of microorganisms in the oral cavity in circulating blood as a result of oral surgery or dental care procedures is much more common than in other areas of the body. Aggressive dental maneuvers that create solutions of continuity of oral mucosa, gingiva, periodontal surgery, periodontal surgery techniques can cause bacteria.

Maxillofacial trauma is any physical trauma to the facial region, commonly encountered by maxillofacial surgeons, and is often associated with high morbidity and so constitute quite a significant portion of the workload of the oral and maxillofacial surgeon. Maxillofacial injuries can occur as an isolated injury or may be associated with multiple injuries in other parts of the body. To assess the patterns, etiology, and treatment modalities of maxillofacial trauma in a teaching hospital in central India, over a 12-year period. Patients with maxillofacial trauma were identified using the department database and clinical records. 264 patients were identified with maxillofacial trauma in the department of oral and maxillofacial surgery between January 2006 and December 2018. The study showed that there was a male preponderance in all age groups over female. Of the 264 patients with maxillofacial injuries, 83,33% had isolated lower face (mandibular) fractures, followed by midface fractures (10.60%) and panfacial fractures (6.06%). Road traffic accidents (87.12%) were the most common form of etiology for trauma followed by assaults (10.98%). Most trauma were treated with open reduction internal fixation (89%) than closed reduction (11%). The etiology and pattern of maxillofacial injuries reflect the trauma patterns within the community and can thus provide a guide to help design programs toward prevention and treatment.

BACKGROUND Maxillofacial surgeries vary from simple tooth extraction to maxillofacial reconstruction and rehabilitation. The intricate anatomy of the facial bones and complex vital structures surrounding them makes it challenging for the surgical teams to perform complex surgeries. With the rapid change in technology and modern advancement in virtual surgeries, there is a leap towards improvement in healthcare. To study biomechanical properties, it is imperative to include the principles of physical science in the field of medicine. In recent times, Finite element analysis (FEA) has become a useful tool to study the biomechanical properties of craniofacial structures under different mechanical parameters. Since the human structure's biomechanics is not possible to study on an experimental basis, finite element analysis has become an emerging tool to solve these complex biomechanical equations. The finite element method uses a numerical calculation of small heterogeneous geometry into the simple linear equation and predicts biomechanical responses towards each variation. Although used extensively in engineering, this method finds extensive use in the medical field, from planning surgeries to design external prosthesis. This method's most significant advantage includes studying a model outside the body, designing an idle surgical instrument and hardware, models that can be replicated based on user requirements, no ethical consideration needed, and print prosthesis that exactly resembles a typical anatomical structure. This method has certain limitations: high cost, technical flaws, and inability to replicate exact clinical conditions. This review article covers the current FEA scope in maxillofacial surgeries, steps in planning surgeries, advantages, disadvantages and the modifications needed to refine it for future research.

In their previous report, the authors presented observations regarding the long-term application of carbon/carbon implants. After evaluating the good functional and aesthetic results, the effect of the human body on the structure and morphology of the implants was investigated with state of the art methods. An implant retrieved from the body after eight years was compared to implants which were sterilized but not implanted (reference). Carbon and oxygen were the main components of both implants, however, as a result of the interaction with the human body the amount of oxygen increased 3–4 times and phosphorus, sulphur, calcium and iron were detectable as trace elements on the surface. The width of the carbon fibres (5–7 µm) building up the implants was not changed during the interaction with the human body. The surface of the implant retrieved from the human body was covered with a 15–17 µm thick layer, not present on the reference implant, having a similar composition to that of the carbon fibres (high amount of calcium that is typical to bone tissue was not detected). According to these results, the structure and the morphology of the implants were not altered notably by the human body. Orv. Hetil., 2012, 153, 744–750.

Considering the probable causal association between the use of bisphosphonates and osteonecrosis of the jaw, as well as the high number of prescriptions and use these drugs every year, this paper aims to show different treatment. The combined use of ozone therapy and laser therapy in tissue regeneration  and bone repair in patients with osteonecrosis induced by bisphosphonates, held by the discipline of Oral and Maxillofacial Surgery and Traumatology, Paulista State University "Júlio de Mesquita Filho". Female patient, white, 53 years after a breast cancer had an evolution for bone metastases throughout the body, and start the chemotherapy treatment using intra-venous pamidronate 90 mg monthly from 2007 which has been used to the present day, due to disease stabilization. The patient sought the institution complaining of painful symptoms in the mandible and maxilla, and the clinical examination and CT were diagnosed initial sites suggestive of osteonecrosis induced by bisphosphonates. In seeking to reduce the symptoms and clinical signs, to prevent progress in the lesions, we recommend treatment by ozone therapy together to infrared low-power laser, which showed satisfactory reduction in bone necrosis sites. Although there are wide variations and difficulties in treatments for osteonecrosis induced by bisphosphonates, it was possible regression of the lesions through the joint processing applied, and the improvement in life expectancy of the patient.

Abstract Introduction The use of drains in Oral and Maxillofacial Surgery is widespread and the securing method using a silk suture laddering along the drain in a standard ‘roman sandal’ pattern is well established. Other methods include tie-lock with sutures and adhesive dressings. We describe the use of a braided device (Braidlock®) without using sutures, based on the concept of a Chinese finger trap, to secure the drain onto patients' skin using tissue adhesive. We report the evolutionary changes of Braidlock. Device Evolution Braidlock® is a Class I non-invasive disposable medical device which provides securement of lines, drains and catheters to a patient using tubing from 3.5Fr to 36Fr. The diameter of the Braidlock® expands when the device is compressed, similar to a ‘Chinese finger trap’. A line can then be inserted through the device and into the body. When decompressed, the Braidlock® squeezes the line tightly and securely. The initial Braidlock® device was hook & loop which required suturing to secure onto skin. Integrated adhesive is a recent invention. Advancement With advances in adhesive dressing and ultrasonic wielding between the plastic casing and adhesive pads, Braidlock® drain securing device appears to be a safe medical device that enables successful securement of drains. Braidlock® may represent a cost saving relative to the conventional suture pack for drain securement. Conclusions This new drain securing device offers a cost effective and reliable alternative to the standard suture fixation. This will eliminate the risk of sharps injury and allow shortening of the drain by ward staff with minimal training.
