Computing on rays: A parallel approach for surface mesh modeling from multi-material volumetric data

AbstractIn this technical report we identify and report a problem with the process of volume to surface mapping that has potentially impacted studies that focus upon local neighborhood connectivity. We show that neighborhood correlations vary spatially with anatomical patterns (gyral structure) even when the underlying volumetric data is uncorrelated noise. We explore the effects of this anomaly across varying data resolutions and surface mesh densities. We finally propose an approach to mitigate these unwanted effects.

Orthodontic Forces

Treatment of impacted teeth often implies placing a bonded attachment and using orthodontic forces to move the tooth into occlusion. The aim of the paper is to describe a novel methodology of manufacturing orthodontic attachments for impacted teeth using the latest CAD software and 3D printing technology. A biocompatible acrylic based resin was used to print a custom made attachment designed based on the volumetric data aquired through cone bean computer tomography. Custom design of the attachment simplified clinical insertion and treatment planning and 3D printing made its manufacturing easier. Being a first trial, more reasearch is needed to improve the methodology and materials used.
