About the Biomaterials and Digital Dentistry Lab

The Biomaterials and Digital Dentistry Lab (BDDL) provides state-of-the-art technology for the evaluation of bonding of restorative materials to sound and decayed dental substrates, as well as physical, mechanical and optical properties of digitally designed dental restorations. Testing includes failure analysis and artificial aging, mechanical testing, and color analysis. Our equipment and expertise are predominantly focused on dental research, but we are able to easily collaborate with other disciplines.

Our mission is to develop high quality research studies in digital technology and dental biomaterials.

 

Research

Different research methods and disciplines are integrated within the DIPRESLAB. 

Surface and Topographic Analysis Research

  • Evaluation of surface characteristics, including 2-dimensional and 3-dimensional analysis
  • Roughness, surface porosity, transparent and semi-transparent film thickness evaluations

Thermography Research

  • Evaluation of internal and surface temperature changes as well as thermal emission of different bodies, and analysis of thermal changes during chemical and physical reactions

CAD-CAM and 3D Printing Research

  • Stereolithography resin printing, post-processing evaluations, optical scanning, comparison of STL files

Metrology Research

  • Calibration of parts, measurement of the accuracy of objects fabricated with different manufacturing techniques. 2-dimensional and 3-dimensional evaluations.

Wear Testing

  • Two and three body wear tests can be completed parameters as surfaces, speed, and load can be adjusted to the research requirements

Implant Research

  • Implant mechanics, geometry, surfaces, implant mechanical evaluations, simulation of implant insertion, and simulation of implant prosthetics

Torque Analysis

  • Digital evaluation of maximum and minimum rotational torques is possible

About the Researchers

 

Ana Carolina Botta Martins de Oliveira is a tenured Associate Professor in the Department of General Dentistry at Stony Brook University School of Dental Medicine. She serves as the Director of the Division of Operative and Dental Materials and Director of Cariology and Operative Dentistry Courses. Dr. Botta earned her D.D.S. and advanced degrees (M.S. and Ph.D.) in Operative Dentistry from São Paulo State University, Brazil. She was also a visiting research scholar at Case Western Reserve University. Dr. Botta has didactic, clinical and research experience in ergonomics, cariology, dental bonding, CAD/CAM technology and restorative materials. She has published in peer-reviewed journals and attended local, national and international meetings in her area of expertise. Dr. Botta is a member of the Editorial Board of Quintessence of Dental Technology and a scientific reviewer for other journals.

Dr. Clarisa Amarillas Gastelum is an Assistant Professor in the Department of General Dentistry at Stony Brook University School of Dental Medicine. She serves as Director of Dental Morphology and Occlusion and Advanced Esthetic Concepts Courses. She received her dental education at the Universidad Autonoma de Sinaloa, Culiacan, Sinaloa, Mexico. Following this she obtained a Certificate in Advanced Operative Dentistry and a Master’s in Science in Craniofacial Biology from the University of Southern California. Her research focuses on dental biomaterials, adhesive dentistry and digital CAD/CAM technology.
