Ultrasonic-assisted drilling of cortical and cancellous bone in a comparative point of view

Heliyon
Background: During bone drilling, a common procedure in clinical surgeries, excessive heat generation and drilling force can cause damage to bone tissue, potentially leading to failure of implants and fixation screws or delayed healing. With this in mind,

Combining the effects of undersized drilling and bone density on implant insertion torque

Brazilian Journal of Oral Sciences, 2017
Aim: This study evaluated the influence of surgical undersized drilling on insertion torque of an implant system at low bone density. Methods: Implant site preparations were made in two polyurethane foam blocks with different densities, where two ...

Bone Drilling: Review with Lab Case Study of Bone Layer Classification Using Vibration Signal and Deep Learning Methods

Eng
In orthopedics, bone drilling is a crucial part of a surgical method commonly carried out for internal fixation in bone fracture treatment. The primary purpose of bone drilling is the creation of holes for screw insertion to immobilize fractured parts ...

Thermal Management of Bone Drilling Based on Rotating Heat Pipe

Energies, 2021
Bone drilling is a common surgical operation, which often causes an increase in bone temperature. A temperature above 47 °C for 60 s is the critical temperature that can be allowed in bone drilling because of thermal bone osteonecrosis.

Drilling down to the bone: Evaluating Bone Marrow Lesions in Osteoarthritis [PDF]

, 2018
Osteoarthritis (OA) is the most prevalent form of arthritis worldwide and affects the whole joint. Changes in cartilage integrity, subchondral bone, and synovitis are recognised during OA progression. Although advances have been made in our understanding

Ultrasonic needles for bone biopsy [PDF]

, 2017
Bone biopsy is an invasive clinical procedure where a bone sample is recovered for analysis during the diagnosis of a medical condition. When the architecture of the bone tissue is required to be preserved, a core-needle biopsy is taken.

Antarctic climate, Southern Ocean circulation patterns, and deep water formation during the Eocene [PDF]

, 2017
We assess early-to-middle Eocene seawater neodymium (Nd) isotope records from seven Southern Ocean deep-sea drill sites to evaluate the role of Southern Ocean circulation in long-term Cenozoic climate change.
