Performance evaluation of a low-cost Ti-Mo-Fe (TMF8) as a replacement for Ti-6Al-4V for internal fixation implants used in mandibular angular fractures: a finite element analysis study.

Stainless steel and titanium-based alloys have been the gold standard when it comes to permanent implants and magnesium-based alloys have been the best option for bioresorbable alloys. Ti-6Al-4V, Ti-64, with its 110 GPa Young's Modulus is the most commonly employed alloy to manufacture biomedical implants used for treatment of fractures of skeleton. Recently, researchers have developed a new low-cost and toxic Vanadium-free alternative to this alloy, Ti-3Mo-0.

A Clinical and Radiological Investigation of the Use of Dermal Fat Graft as an Interpositional Material in Temporomandibular Joint Ankylosis Surgery.

Management of temporomandibular joint (TMJ) ankylosis is mainly through surgical intervention. Interpositional materials are a necessity when it comes to prevention of TMJ re-ankylosis after arthroplasty. Early aggressive postoperative physiotherapy is essential for the prevention or treatment of TMJ hypomobility or ankyloses.

Posttraumatic Lateral Dislocation of Mandibular Condyle: A Proposed New Classification with Report of 14 Dislocated Condyles.

Lateral dislocation of the intact mandibular condyle is a relatively uncommon clinical condition. Since the first description and classification of these dislocations given by Allen and Young, few classification systems have been proposed in literature with incorporation of different patterns of dislocations identified over the years. We share our clinical experience of nine cases of such dislocations with 14 dislocated condyles, and on the basis of clinical and radiological findings coupled with the review of existing classification systems, we propose a new classification system which includes all the possible patterns of such dislocations overcoming the major shortcomings of preexisting classification systems identified by the authors.

Management of Odontogenic Fascial Space Infection in Hemophilia Patients: A Proposed Protocol.

Purpose: The purpose of this study was to suggest a protocol for the management of odontogenic space infections in patients with hemophilia which is often incompletely addressed by clinicians because of the fear of excessive bleeding leading to prolonged morbidity.

Methods And Results: Six diagnosed cases of hemophilia (four cases of hemophilia A and two cases of hemophilia B) with odontogenic fascial space infection were included in the study. Apart from routine investigations, assessments were also done to identify inhibitors to factor VIII/IX.

Decompression of Ludwig's angina in a pregnant patient under bilateral superficial cervical plexus block.

Ludwig's angina is defined as a potentially lethal, rapidly spreading cellulitis, involving the sublingual and submandibular spaces, and is manifested by a brawny suprahyoid induration, tender swelling in the floor of the mouth, and elevation and posterior displacement of the tongue. During a life-threatening infection such as Ludwig's angina, the mother and foetus are vulnerable to septicemia and asphyxia. We describe a case of decompression of Ludwig's angina in a 28 weeks pregnant patient under bilateral superficial cervical plexus block.

Unusual Superolateral Dislocation of Bilateral Mandibular Condyles.

We describe a case of maxillofacial trauma in a paediatric patient in which the left mandibular condyle was superolaterally displaced into the temporal fossa, medial to the zygomatic arch which was intact and the right condyle was also displaced similarly but the zygomatic arch was also fractured on this side. Also, there was an associated mandibular symphyseal fracture.

Unusual Superolateral Dislocation of Mandibular Condyle.

We describe a case of maxillofacial trauma in a pediatric patient in whom the mandibular condyle was superolaterally displaced into the temporal fossa, medial to the zygomatic arch which was intact. In addition, there was an associated mandibular symphyseal fracture. To our knowledge, this case is the first of its kind to be reported in the literature.

Comparative study of detection of bacteremia after different oral surgical procedures.

Introduction: The purpose of this study is to compare the efficiency of culture methods in detecting microorganisms appearing in the bloodstream after various oral surgical procedures and effect of preoperative antibiotics and antiseptic rinses on bacteremia.

Materials And Methods: The prevalence of bacteremia at various intervals of time (pre- and post-surgical) was studied in three different groups presenting with indications to surgical intervention. Two of the groups were given presurgical prophylaxis (systemic antibiotic and antiseptic rinse) while, in one group, no prophylactic measure was adopted.

Traumatic superolateral dislocation of the mandibular condyle: case report and review.

We describe what is to our knowledge the first report of a patient who presented with a superolateral dislocation of the mandible, in which the medial portion of the left condyle was fractured and the lateral fragment was hooked on the zygomatic arch without any other associated fracture.

Trabecular Variant of Juvenile Aggressive Ossifying Fibroma.

Juvenile aggressive ossifying fibroma (JAOF) is an uncommon benign lesion which is distinctly aggressive in behavior with high tendency for recurrence. It appears in early age and in 79% of patients is diagnosed before 15. It has two histological variants: psammomatoid and trabecular, with the latter being less common with a stronger tendency to recur.
