Biomaterials and Restorative Dental Research

Dr. J. Murray Gavel Center for Restorative Dental Research sign

The university welcomes the many valuable contributions from agencies, corporations, foundations, and individuals which makes its mission of extraordinary education, research, and community service possible. We collaborate with multiple schools at Tufts University, as well as nearby colleges and universities, on biomaterials and restorative dental research.

Established in 1992, the Dr. J. Murray Gavel Center for Restorative Dental Research has a long history of performing high-quality bench studies in the area of dental materials research. The center is located at Tufts University School of Dental Medicine in the heart of downtown Boston, MA.

Equipment

Learn more about the equipment available at the Gavel Lab and to view published studies in which the equipment was used.

  • A hand-held dental color analysis system used in collecting precise color information of teeth.

  • A high-performance stereomicroscope used as a visual analysis tool to measure the micro-gap or micro-leakage in the tooth structure. It provides accurate observation, imaging, and analysis of samples without standing clarity and detail.

  • A cutting-edge digital impression system used in dentistry to capture accurate and detailed 3D images of a patient's teeth and oral structures. It utilizes advanced optical technology to replace traditional, uncomfortable dental impressions with amore convenient and patient-friendly digital solution.

  • A versatile and powerful materials testing machine commonly used in the field of mechanical testing. It is designed to accurately measure and analyze the mechanical properties of a wide range of materials, including metals, plastics, composites, and biomaterials.

  • This precision cutting machine is ideal for delicate parts by only using gravity fed force. Its great versatility in chucking allows for holding all types of sample shapes and configurations giving today’s laboratory a precision cutting machine capable of sectioning virtually any material including teeth, composites, cements, laminates, plastics, and biomaterials.

  • A specialized device used to simulate the brushing actions. It is commonly used to evaluate the performance and durability of toothbrushes, quality control, and regulatory testing within the oral care industry.

  • Provides simple operation form anual grinding and polishing for sample preparation to be studied and evaluated further.

  • A specialized instrument used to assess the hardness or resistance to deformation of materials at a microscopic level. By creating indentations on the testing surface of the material under specific testing condition, it quantifies the material’s hardness. It provides the valuable information for understanding materials properties and quality control.

  • A machine that simulates the thermal stresses that natural teeth, restored or not, are exposed to in the mouth over time. It features a motorized arm that moves specimens between a heated water bath and are frigerated water bath. The effects of aging, such as degradation, microleakage, or changes in mechanical properties, can be studied.

  • The Biocompatible resin-based 3Dprinters are safe for intraoral use. It can be used to print: 

    • Ceramic crowns
    • Clear aligners
    • Indirect bonding trays
    • Night guards
    • Dental models
    • Surgical guides
  • This device has numerous applications such as: 

    • Basic shade determination for the selection of CAD/CAM materials, materials for direct fillings, and prosthetic teeth
    • Tooth-area shade determination for the fabrication of layered ceramic restorations and for use in bleaching
    • Shade determination for restorations even duringfabrication of restorations
    • Quality control through comparison of fabricated ceramic restorations with regard to planned and actualresults
    • Intaoral and extraoral shade determination of existing ceramic restorations
