Offense or defense?
I recently read a description of a research project that was an obvious disappointment to the people involved. It was a simple and well-motivated affair; the researchers wanted to relate…
User acceptance of a touchless sterile system to control virtual orthodontic study models
Introduction In this article, we present an evaluation of user acceptance of our innovative hand-gesture–based touchless sterile system for interaction with and control of a set of 3-dimensional digitized orthodontic…

Facial surface morphology predicts variation in internal skeletal shape
Introduction The regular collection of 3-dimensional (3D) imaging data is critical to the development and implementation of accurate predictive models of facial skeletal growth. However, repeated exposure to x-ray–based modalities…
Objective vs subjective analyses of arch form and preformed archwire selection
Introduction Maintaining a patient’s original arch form increases treatment stability. In this study, we assessed the agreement between subjective analyses of arch form and archwire selection by orthodontists and an…
BoneCeramic graft regenerates alveolar defects but slows orthodontic tooth movement with less root resorption
Introduction BoneCeramic (Straumann, Basel, Switzerland) can regenerate bone in alveolar defects after tooth extraction, but it is unknown whether it is feasible to move a tooth through BoneCeramic grafting sites….
