Photoelasticity in Dentistry: a literature review

Resumo

Photoelasticity consists of an
experimental technique of stress analysis. This technique is very used
in most different areas including Dentistry. This literature review
presents the several applications of photoelastic technique in Dentistry the several applications of photoelastic technique in Dentistry
as well as its advantages and disadvantages. Literature review:
Based on this method of analysis, it is possible the verification of
the stress distribution and deformation in structures with complex
geometry as maxilla and mandible. It can be used to evaluate the
distribution of stress on several types of prosthesis as removable
partial denture systems with different retention systems, conventional
implant prosthesis, overdentures and Brånemark protocols. Moreover,
photoelasticity can be used to assess the stress generated by various by various
orthodontic movements, different orthodontic systems and different
materials (orthodontic wires). In addition, it is used to analyze
different defects of maxillectomy, splint types on traumatized tooth
and post-core restoration methods. This technique can also be
used to assess dental instruments such as evaluation of different
designs of periodontal probe. Conclusion: The photoelastic analysis
has been a technique of great importance in health area studies,
more specifically in Dentistry. Based on this method of analysis, it
is possible to measure the stress distribution and deformation in
structures with complex geometry as maxilla and mandible.
