Areas of Interest
The research interests of our laboratory include the
development of new biomaterials, studies of structure-property
relationships, surface analysis and clinical trials of
restorative dental materials.
Currently, the work on new materials involves investigations
of the dental applications of fiber-reinforced composites. These
materials are used as structural members in various clinical
situations, such as prosthodontic frameworks, retainers, splints
and orthodontic archwires. The materials are based on continuous
fiber reinforcement of thermoplastics and thermosets. The
research includes studies of the fiber-matrix interface, bulk
mechanical and physical properties, appliance design and
clinical trials. Modes of failure identified in clinical trials
are used to construct computer and laboratory models, which
allow optimization of materials and design. Research tools
include SEM, XPS and FEA.
Surface analysis work is primarily in collaboration with
research directed by Dr. Gloria Gronowicz, on the effect of
implant materials on osetoblasts. Disks of clinical and model
alloys are prepared with well-defined surfaces and analyzed with
SEM, EDX, XPS, AES and profilometry. Results are correlated with
biological assays to understand the effects of topography and
chemistry.
