BACKGROUND Fractures of the mandibular angle are common and comprise 31% of all mandibular fractures. Multiple recent studies report a 2-3 fold increased risk for mandibular angle fractures when un-erupted mandibular third molars are present. The objective of this study was to assess the frequency of un-erupted mandibular third molar in mandibular angle fractures. METHODS This cross-sectional...

Chipping in glass plates from line-wedge contact loading is studied as function of the wedge’s subtended angle 2β, its inclination angle φ, and the distance h from a corner having a subtended angle 90◦−θ . A brittle-fracture analysis in conjunction with the FEM technique is used to elucidate the role of geometric variables on chip morphology and chipping load. Closedform relations are developed...

OBJECTIVE To estimate the relative risk of mandibular angle fractures among people with a lower third molar compared with those without a lower third molar. METHODS Data for a case-control meta-analysis were obtained by performing a literature search in MEDLINE and EMBASE to identify suitable observational studies. To be included, studies had to present data on patients with mandibular fractu...

To investigate the effects of abutment taper angles on the fracture strength of dental implants with TIS (taper integrated screwed-in) connection. Thirty prototype cylindrical titanium alloy 5.0mm-diameter dental implants with different TIS-connection designs were divided into six groups and tested for their fracture strength, using a universal testing machine. These groups consisted of combina...

BACKGROUND Bone mineral density (BMD) has been shown to be a consistent and independent risk factor for distal radius fracture. Inconsistent data have been reported on the association between BMD and severity of distal radius fracture. Our primary aim was to explore if there is an association between cortical BMD at the hand and the severity of fragility distal radius fracture. METHODS Consec...

BACKGROUND Neglected fracture of neck of femur in young adults is a major problem in developing countries. Existing treatment options varies from osteotomy to various graft techniques (muscle pedicle, vascularized and nonvascularized fibula etc.). There is paucity of literature regarding the use of double angle barrel plate and hip screw in such cases. We conducted a prospective longitudinal ob...
