In vivo changes in dental implant temperatures during hot beverage intake: a pilot study.
OBJECTIVE
The aim of this study was to measure the increase in temperature in dental implants during the intake of hot beverages in vivo.


METHODS
Eight successfully osseointegrated implants in 7 subjects were examined. Each subject was asked to drink the same volume of hot beverage. While drinking, temperature changes were recorded via 3 embedded thermocouples placed (i) in the implant's internal space, (ii) at the implant-abutment interface, and (iii) at the abutment. All thermocouples were linked to a computer and analyzed with appropriate software.


RESULTS
The maximum temperatures were 47.3 degrees C at the abutment, 45.6 degrees C at the implant's internal space, and 44.6 degrees C at the implant-abutment interface. A linear correlation was found between the temperatures measured (i) at the implant abutment and in the implant's internal space, and (ii) at the abutment and at the abutment-implant interface.


CONCLUSIONS
Further clinical studies are required to determine whether the habitual consumption of hot food and beverages may be considered a risk factor in the success of implant-supported prostheses.
