Abstract The influence of the acuteness of the model angle and the direction of printing was investigated on different three-dimensional (3D) printers to understand the fidelity of 3D printing. A Polyjet printer and two fused deposition modeling printers were used in the present study. Computer-aided design (CAD) models were designed in the form of a triangular prism with a height of 15 mm and with varying angles of 60°, 45°, 30°, 20°, 10°, and 5°. From the CAD designs, additive manufacturing (AM) models were printed in three different directions by each of the three printers. To investigate the global fidelity of the 3D printers, the height and surface outlines of the AM model cross sections were measured. The fidelity of the AM models with increasingly acute angles was no…

Using morbidity and income data to forecast the variation of growth and employment in the oral healthcare sector
Abstract The perception of the health sector from an economic policy point of view is changing. In the past, health expenditure was mostly seen as a “cost” item, probably because many medical treatments are covered by public health insurance. However, policymakers are increasingly realizing that a growing health sector may be quite beneficial for an economy. It creates employment opportunities and it is relatively resistant to the fluctuations of the business cycle. Input–output analysis could be a useful tool to study the structural change resulting from the growth of the health sector. This paper quantifies for the first time the economic significance of the oral healthcare sector as a component of the German healthcare sector as a whole. The current data for the healthca…

Correction of cheek biting in a dentate patient
Publication date: Available online 18 March 2016 Source:The Journal of Prosthetic Dentistry Author(s): Dheeraj Koli, Harsimran Kaur, Aditi Nanda, Mahesh Verma, Karan Manak, Rekha Gupta, Shubhra Gill Postsurgical injury by teeth to oral mucosa (reconstructed by a flap) can lead to ulceration and subsequent infection at the reconstructed site. A prompt intervention by fabricating a specially designed prosthesis to deflect the reconstruction flap away from the occluding teeth has been described for the treatment of cheek biting in the present clinical report.

A 5-year perspective on a removable overdenture appliance for a patient with osteonecrosis of the jaw, a mandibular resection, and rampant caries
Publication date: Available online 18 March 2016 Source:The Journal of Prosthetic Dentistry Author(s): Gary R. Login A 78-year-old man with a history osteonecrosis of the jaw and 2 subsequent surgeries to repair a fractured mandible had a condition that contraindicates most dentoalveolar procedures to restore his failing dentition. A Snap-On-Smile overdenture restored his opportunity for natural speech, occlusal function, and esthetics. (Source: The Journal of Prosthetic Dentistry)
