Although alginate impression materials are not considered the first choice for scientific research we constantly receive very interesting research results from universities all over the world.
- From our dealer Dental News in Brasil we recently received a poster performed by Professor Tarcisio José de Arruda Paes Junior (Department of Dental Materials and Prosthodontics Institute of Science and Technology - UNESP, Sao Paulo, Brazil)
The objective was to evaluate the precision of edentulous gypsum anatomic models obtained from alginate impressions.
Influência da técnica de dupla moldagem en alginato na reprodutibilidade de arcos totalmente desdentados
- Two other very interesting poster presentations were created under the supervision of Professor Paul Hansen (Department of Restorative Dentistry, University of Nebraska Medical Center, Lincoln, Nebraska)
The first project, performed by Dr. Raul Franco, evaluates distortion in gypsum models that have been prepared from wax-lined and unlined metal impression trays.
Quality of Gypsum Casts Comparing One-Stage and Two-Stage Pour Methods
The second project was performed by Dr. Christian Petersen. In this study two gypsum pour methods were evaluated.
Wax Lining an Impression Tray, Will it Cause Distortion?
