“…In contrast, a conflicting result emerged from the work of Feuerstein et al, where the apical portion of the implant recorded a slightly higher temperature level, nearly reaching 45°C, as compared to our findings [13]. A similar pattern of results was also observed in a more recent study by Babayi et al, where the implant's apical portion displayed greater susceptibility to bone necrosis, with a maximum temperature value of approximately 47°C [22]. Various factors could contribute to these discrepancies, including differences in heat source conditions, measurement locations, or even variations in implant design.…”

Hot substance consumption can have adverse effects on the neighbouring bone tissue in proximity to a dental implant. Elevated temperatures at the interface between the bone and implant could potentially disrupt the local cellular processes crucial for osteointegration. The primary goal of this study was to analyse the temperature and heat flux distributions within the implant body, surrounding bone, and bone-implant interface when the implant system subjected to a thermal load of transient nature. Transient thermal finite element analysis was utilised to analyse a three-dimensional model of dental implant with three different lengths – 6, 10, and 13 mm – placed in a mandible section. In order to obtain realistic results, thermal load was applied through convection on the outer surface of the prosthesis, simulating exposure to a hot liquid with the temperature and convection heat transfer coefficient of 67°C and 0.005 W/mm2°C, respectively. The temperature of the other components in the model was maintained at a constant 37°C. The results showed that increasing the implant length generally led to lower temperature and heat flux levels in the implant body, bone, and bone-implant interface. The highest temperature and heat flux values were concentrated in the superior region, gradually decreasing toward the inferior region. Importantly, all maximum temperature values remained below the limits associated with cellular bone necrosis and remodelling, thereby reducing the risk of osteoporosis. It is noteworthy that, when considering transient thermal load, shorter implants pose a significantly higher risk of implant failure compared to longer ones.

Mechanical and Thermal Stress Behavior of a Conservative Proposed Veneer Preparation Design for Restoring Misaligned Anterior Teeth: A 3D Finite Element Analysis

2020

The objective of this study was to evaluate the biomechanical and thermal behavior of a proposed preparation design as a conservative treatment option that aims to preserve both gingival and tooth health structures through a comparative finite element analysis with non-preparation and conventional designs. 3D solid models of laminate veneers with different preparation designs were obtained using cone-beam computed tomography (CBCT) scanning of the maxillary incisor. A 100-Newton load was applied with angulations of 60° and 125° to the longitudinal axis of the tooth to determine the stresses during mastication. In addition, transient thermal analysis was performed to compare the temperature and thermal distribution of the restored tooth models when subjected to thermal loads of 5 °C and 55 °C. Teeth prepared with the proposed design showed lower stress distributions and a repairable failure mode, followed by the non-preparation design, while teeth prepared with the conventional design showed the highest stress concentrations. Furthermore, cold thermal loading yielded larger thermal stress distributions than hot thermal loading, independent of the preparation type, and the effect of temperature changes were within the critical limit near the pulp and dentin regions. Thus, the preparation design geometry affects the long-term success of laminate restoration, and the proposed design yields more uniform and appropriate stress distributions than the other techniques.

Geriatric Dentistry in the Age of Digital Technology

View full text Add to dashboard Cite

Elderly dental patients suffer from toothache and lose their teeth without proper care, particularly diabetics and other chronically ill people who used to suffer from more dental problems and fear of surgery or implantation techniques. These patients also avoid visiting doctors or dentists for treatment and suffer from not eating or chewing. Hence, a study was conducted to study the barriers to geriatric dentistry among patients above the age of 60/65 in Odisha. Further selection of dental implant materials for elderly people was done by E_DAS (evaluation based on distance from average solution) multi-criterion decision-making method, such that the best implant material could be prioritized. Then the statistical study on site selection for implants is conducted with variations in temperature during the tooth implantation process. This chapter will help in the proper selection of dental materials by considering older patients. It will also help guide the proper and better treatment procedures for senior people, which can reduce the fear factor in dental treatment.
