A low thermal conductivity is desired in restorative materials used on the tooth whereas a high thermal conductivity is desirable where the material covers soft tissue. Dental Cements; Dental Materials Zirconia presents a thermo-conductivity much lower than that of other framework materials. It may induce thermal cycling delamination of the veneering porcelain. Sintered Materials The Dental Care Cost Estimator provides an estimate and does not guarantee the exact fees for dental procedures, what services your dental benefits plan will cover or your out-of-pocket costs. 2. In addition, the effect on thermal conductivity of concentration and type for five resin‐reinforcing fillers was investigated. These Mcqs are helpful for Medical students.
