“…In an experimental study with an implant within a plastic replicate of the bone, Livne et al (2014) exposed a 60°C hot liquid to the model and measured different points on the implant. They found that the temperature at the interface may be increased near 48°C [30], which is well-coincided with the present results. The main reason for this agreement could be the same heat source conditions, same measuring location or even the similar implant design.…”

Background: Consumption of hot substances may harm the surrounding bone around a dental implant. High temperatures at the bone-implant interface (BII) interferes with local cellular activities involved in the osteointegration. Objectives: The present study was aimed at calculating the temperature distribution through the BII and the jaw bone under application of a transient cyclic thermal load. Methods: In this numerical simulation, finite element method was employed in a commercialized dental implant model drawn by computer-aided design tools based on CT data to find the temperature in superficial and deep bone regions near the BII. The heat load was applied cyclically during the intake time. Results: Results showed that the highest temperature was occurred at the top regions of the interface by magnitude of 48 C. Removal of the thermal loads also was followed by rapid decrease in the bone temperature. Conclusions: Routine beverages of a hot liquid can increase the temperature of the bone beyond the biological thresholds of the bone cells vitality or remodeling functionality, specifically in the delayed loading types of implantation.

“…For comparison purposes, the temperature was determined at three heights of the implant, similar to previous studies . They represent temperatures at, respectively, the surface exposed to heat loading (P1), the cervical implant/bone interface (P2), and the apical implant/bone interface (P3).…”

“…Previous studies have shown that at 42°C some bone proteins are lost, and if the compact bone is exposed for 1 minute to a temperature of 47°C, it becomes necrotic . According to Livne et al, heating the bone at 40°C for 7 minutes causes bone necrosis …”

“…In BHI implants, artificial crowns are placed on the implant body after 3 to 6 months . Dental implants are usually made up of metal, and the thermal conductivity of metal is more than that of body tissues, thereby increasing the thermal conduction flow between the jawbone and the oral cavity . Subsequently, the amount of heat transferred to the jawbone increases, potentially causing severe damage to the surrounding tissues.…”

“…Moreover, most of the heat transfer took place in the cervical region of the implant, which may have been biologically harmful. They concluded that less heat was transferred in the presence of the interim prosthesis …”
