A model of temperature transients in dental implants

A hypothetical heat conduction model is investigated to determine the ranges of temperature gradients that might occur in implants. This model showed that a 60 degrees C heat source will cause a heat front of > or = 47 degrees C to advance > 3 mm down an implant within one second. Oral temperature transients may be a factor in implant pathology.

OBJECTIVES The habitual consumption of extremely hot foods and beverages may affect implant treatment modality. Our objectives were to: (i) establish the maximum temperature produced intra-orally while consuming very hot substances and (ii) use these values in an ex vivo model to assess the temperature changes along the implant-bone interface.
