Titanium screws have properties that make them ideal for applications that require both a high strength-to-weight ratio and corrosion resistance, such as fastener applications for aviation and aerospace. The fracture behavior of Ti-10Mo-8V-1Fe-3.5Al (TB3) alloy screws during assembly was explored. Besides visual examination, other experimental techniques used for the investigation are as follow...

BACKGROUND For implant-supported hybrid prostheses, high mastication forces and reduced acrylic resin thickness over a metal substructure often cause failures arising from tooth or resin fractures. To assay fracture resistance of artificial teeth and resin in implant-supported hybrid prostheses in relation to the titanium structure and retention design supporting teeth. MATERIAL AND METHODS 4...

There are serious problems with existing methods of treating pilon fractures of the tibia caused by high-energy trauma. The method chosen to treat these fractures should not raise the risk of infection while effectively restoring the joint surface. We successfully treated a 42-year-old male patient with a pilon fracture caused by high-energy trauma using an arthroscopy-assisted unilateral exter...

BACKGROUND Microwave is a method for improving fracture repair. However, one of the contraindications for microwave treatment listed in the literature is surgically implanted metal plates in the treatment field. The reason is that the reflection of electromagnetic waves and the eddy current stimulated by microwave would increase the temperature of magnetic implants and cause heat damage in tiss...

Aims: The present study is to evaluate the effect of internal fixation with cancellous bone screws in the treatment for femoral neck fractures. Methods: A total of 64 patients with femoral neck fractures hospitalized at our hospital from January 2014 to December 2014 were included in the present study. The 64 patients were randomly divided into Con group (internal fixation by thread needles; n ...

The purpose of this study is to evaluate the fitting accuracy and fracture resistance of crowns using a hybrid zirconia frame made of both porous and dense zirconia. Commercial semi-sintered zirconia, sintered dense zirconia and sintered hybrid zirconia were used. Sintered zirconia was milled using the CAD/CAM system, and semi-sintered zirconia was milled and sintered to fabricate molar crown f...

A rare injury of the wrist, scapho-capitate fracture syndrome, in a young patient is reported. Despite early recognition of the injury and surgical intervention, the scaphoid fracture did not unite and another attempt to achieve union with bone grafting and internal fixation also failed. The wrist continued to be painful and stiff. Radiographs of the wrist, 18 months after the injury, showed no...

Fracture of the anatomic neck of the humerus is often associated with glenohumeral dislocation. One of the main consequences of anatomic neck fracture is necrosis. Hertel et al showed that with intra-articular fracture of the humeral head, anatomic neck fracture and concurrent disruption of the medial vascular hinge lead to a high risk of necrosis. Loofburrow was the first, in 1905, to describe...

Background: Proximal humerus fractures are very common fractures occurring in the skeleton. They account for approximately 4 – 5% of the fracture attendance at the hospital. It is the most common fracture of shoulder girdle. It is the 3rd most common fracture in elderly. Till date various methods are used including percutaneous and open reduction & fixation according to fracture type. Aims & Ob...
