Purpose Compression necrosis refers to bone tissue damage that can occur when excessive pressure or force is applied to surrounding bone during implant placement. This pressure can compromise blood supply to the bone, leading to necrosis. Compression necrosis is a concern, because it can affect the stability and long-term success of dental implant. Patients and Methods This case report highlights a case of early bone loss and implant failure possibly due to compression necrosis. Clinical data, photographs, radiographs, blood examination report and histology were presented to document the early failure of an implant placed in the mandibular left posterior region of a 33-year-old female patient. Results Radiograph taken six weeks after implant placement showed severe angular defect. Therefore, the implant was surgically removed. Histological examination of the area showed bony trabeculae with an absence of osteoblastic riming, suggestive of necrotic bone. Conclusion Using excessive torque values when placing implants in dense bones can increase the risk of implant failure due to bone over compression. Dental professionals must follow the manufacturer’s instructions and employ quality surgical techniques during implant placement into dense cortical bone to minimise risks.

“…Replacing missing teeth is often done using dental implants, which are widely embraced as a common and popular alternative [1,2]. Positioned within the alveolar bone beneath, these implants provide support for various dental applications, including single-tooth replacement, anchored bridges, and full-arch rehabilitation [3].…”

A prevalent and widely favoured solution for replacing lost teeth is the use of dental implants. The removal of dental implants, even when they are osseointegrated but unsuccessful, can be traumatic, resulting in the loss of healthy bone and adding complexity to the treatment procedure. Reducing the trauma associated with implant removal can be achieved by intentionally weakening the bone-implant attachment. To achieve this objective, a suggested approach involves utilising thermal necrosis to aid in the minimally invasive removal of implants. The objective of this study was to use finite element analysis to explore the optimal power output for intentionally inducing thermal necrosis in a dental implant. SolidWorks software was utilised to create a three-dimensional model of a dental implant assembly, which includes an abutment, screw, and implant body integrated into a segment of mandibular bone. The model was subsequently analysed using ANSYS software, applying device powers ranging from 5 to 40 W in 5 W increments on the top surface of the abutment. The results of the study showed that there was a considerable elevation in the temperatures of the bone and implant, even when employing the low power settings commonly used in electrosurgical procedures. Elevating the power level has led to a decrease in the time required for the bone and implant to reach 47°C, the initial temperature at which bone necrosis occurs. However, it is crucial to take into account the significant temperature rise in the implant body at higher power levels. The implementation of lower power settings could present a viable approach to achieving controlled osteonecrosis.

“…The stability of a dental implant heavily relies on osteointegration with the surrounding area [3,4]. This process involves an uptick in bone density near the implant site, facilitated by the activation of osteoblast cells, which in turn bolsters the implant's anchoring and improves its chances of longterm success.…”

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.
