Patient-specific finite element analysis for assessing hip fracture risk in aging populations.

The femur is one of the most important bone in the human body, as it supports the body's weight and helps with movement. The aging global population presents a significant challenge, leading to an increasing demand for artificial joints, particularly in knee and hip replacements, which are among the most prevalent surgical procedures worldwide. This study focuses on hip fractures, a common consequence of osteoporotic fractures in the elderly population.

Air-Abrasion in Dentistry: A Short Review of the Materials and Performance Parameters.

The selection of abrasive material and parameters of the Air-Abrasion device for a particular application is a crucial detail. However, there are no standard recommendations or manuals for choosing these details; the operator must depend on his experience and knowledge of the procedure to select the best possible material and set of parameters. This short review attempts to identify some of the effects that the selection of material and parameters could have on the performance of the Air-Abrasion procedure for a particular application.

CFD investigation of multiple peristaltic waves in a 3D unobstructed ureter.

Ureters are essential components of the urinary system and play a crucial role in the transportation of urine from the kidneys to the bladder. In the current study, a three-dimensional ureter is modelled. A series of peristaltic waves are made to travel on the ureter wall to analyse and measure parameter effects such as pressure, velocity, gradient pressure, and wall shear at different time steps.

Wear estimation of hip implants with varying chamfer geometry at the trunnion junction: a finite element analysis.

The hip joint helps the upper body to transfer its weight to lower body. Along with age, there are various reasons for the degeneration of the hip joint. The artificial hip implant replaces the degenerated hip.

Computational flow analysis of a single peristaltic wave propagation in the ureter.

Background And Objective: The bladder receives the urine from the kidney and ureter. The series of peristaltic waves facilitate urine transport to the bladder. The peristaltic flow in the ureter is associated with fluid trapping and material reflux, which may cause an increase in bladder pressure.

Finite element analysis of immature teeth filled with MTA, Biodentine and Bioaggregate.

Background And Objective: Finite element based simulation has emerged as a powerful tool to analyse the tooth strength and its fracture characteristics. The aim of this study is to compare and evaluate the fracture resistance of immature teeth reinforcement with MTA, Biodentine and Bioaggregate as an apical plug and backfill material using Finite Element Method.

Methods: A 3D finite element analysis model was generated using a simulated immature maxillary central incisor.

Photobiomodulation therapy in neuroischaemic diabetic foot ulcers: a novel method of limb salvage.

Objective: Low-level laser therapy (also known as photobiomodulation therapy, PBMT) promotes accelerated healing of diabetic foot ulcers (DFUs), thereby preventing the risk of future complications and amputation. The aim of this study was to determine the effect of PBMT, with structured, graded mobilisation and foot care, on DFU healing dynamics.

Method: Patients diagnosed with type 2 diabetes, diabetic peripheral neuropathy and presenting with a chronic neuroischaemic DFU, were treated with PBMT using scanning and non-contact probe methods.
