Mantis shrimp are renowned for their unusual method of breaking shells with brief, powerful strikes of their raptorial appendages. Due to the extreme speeds of these strikes underwater, cavitation occurs between their appendages and hard-shelled prey. Here we examine the magnitude and relative contribution of the impact and cavitation forces generated by the peacock mantis shrimp Odontodactylus...

Fracture of the mandible during exodontia is fortunately rare, but is under-reported. A review identified 189 documented cases of iatrogenic fractures of the mandible (IFM) associated with the removal of teeth. The reasons for its occurrence are thought to be multifactorial and include age, sex, degree of tooth impaction, relative volume of the tooth in the jaw, pre-existing infection or bony l...

Mandibular fracture is usually the clinical end of bisphosphonate-related osteonecrosis of the jaw. This is a painful complication and patients cannot feed as usual, with a worsening of their quality of life. The goal of treatment in bisphosphonate related osteonecrosis of jaw (BRONJ) patients is to slow progression of bone necrosis. We present a novel technique for treatment of severe mandibul...

INTRODUCTION Osteoporosis and tooth loss have been linked with advancing age, but no clear relationship between these conditions has been proven. Several studies of bone mineral density measurements of the jaw and spine have shown similarities in their rate of age-related deterioration. Thus, measurements of jawbone density may predict lumbar vertebral bone density. Using jawbone density as a p...

: This case report described a 10-year-old girl injured during sports accident. Clinical examinations disclosed the extrusion, crown fracture, and subluxation of anterior teeth each jaw. At same time, dental fragments were embedded within lower lip soft tissue - projected procedures concerned maintaining pulp vitality periodontal stability fractured with an 18-month follow-up.

Introduction: In open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. This study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment.    Materi...

The high level of development modern medicine cannot reduce the growing prevalence various types pathologies and injuries in people different ages. Recently, a fracture lower jaw is often found among student youth. In this regard, issue improving rehabilitation young with type injury relevant. importance problem associated frequency such an increase number complications developing against

AIMS We analyze the possible clinical differences between bone jaw exposed areas in ONJ (osteonecrosis of the jaws) and ORN (osteoradionecrosis). PATIENTS AND METHOD Group 1 was composed with 53 ONJ cases and group 2 with 20 ORN cases. In both groups we analyzed, the major size of the exposed bone areas, the number of exposed areas, the location on the jaws and the presence of others associat...
