Initial stability measurement of dental implants placed in different anatomical regions of fresh human cadaver jawbone.

Statement Of Problem: Initial implant stability has been used as an indicator for future osseointegration and whether an immediate/early loading protocol should be applied. However, differences in initial stability in relation to anatomical regions of jawbone have not been studied extensively because of the risks involved with stability measurements.

Purpose: The purpose of this study was to determine whether initial implant stability varies with anatomical regions of the jawbone.

Investigation of non-uniform airflow signal oscillation during high frequency chest compression.

Background: High frequency chest compression (HFCC) is a useful and popular therapy for clearing bronchial airways of excessive or thicker mucus. Our observation of respiratory airflow of a subject during use of HFCC showed the airflow oscillation by HFCC was strongly influenced by the nonlinearity of the respiratory system. We used a computational model-based approach to analyse the respiratory airflow during use of HFCC.
