The study of expertise in surgery aims to facilitate the development of improved training methods by understanding the characteristics of expert practitioners. In this article and its companion, we present our study of the characteristics of competence and expertise in the field of oral surgery. We observed participants of different skill levels as they performed an ex vivo drilling task design...

The aim of the present study was to compare bone-collecting capacity of bone harvesting device and minimally irrigated low-speed drilling using three implant systems. One bone harvesting device and three commercially available drill systems were compared using the osteotomies on bovine rib bones. The amount of the collected bone particle and particle size (<500 μm: small, 500-1000 μm: medium, a...

The goal of this study was to investigate if the preparation of implantation site affects bone formation inside tissue engineering scaffolds. For this purpose, two different drilling techniques were used to create a hole in distal femurs of rats before the insertion of a bone scaffold: a manually driven wood drill bit and an electrically driven metal drill bit. The size and the position of the ...

BACKGROUND The coverage of the atelocollagen membrane at the chondral defect after subchondral drilling might improve the beneficial effects for cartilage repair because of the prevention of scattering and accumulation of cells and growth factors from bone marrow within the chondral defect. On the other hand, it might block cells and factors derived from the synovium or cause high pressure in t...

Introduction. Radical procedures like calcanectomy and amputation performed for calcaneal osteomyelitis are regarded as effective in eradication of infection even though potentially functionally disabling. Bone sparing procedures offer better functional result at the expense of potentially worse infection control. The aim of the study has been to assess the influence of the surgical radicalism ...

BACKGROUND The increasing incidence of prosthesis revision surgery in the Western world has led to an increased focus on the capacity for stem removal. We previously reported on a femoral stem implanted in goats with an approximate 15% reduction in retention force by drilling longitudinally orientated grooves on the side of the stem. In this current study, we aimed to histologically evaluate th...

Bone drilling is a routine operation in surgeries, such as neurosurgery and orthopedics. However, the excessive temperature may cause severe thermal damage to bone tissue. Therefore, determination of tissue can reduce harm caused by damage. A time-varying field simulation model was set up ABAQUS software this paper, based on Johnson-Cook model. Then it validated with experiments cortical fresh ...

BACKGROUND Hypoglossal-facial anastomosis is the gold standard treatment for facial reanimation in those cases where the facial nerve has been damaged near the brainstem. The technique that requires temporal bone drilling and partial section of the hypoglossal nerve is usually preferred. This technique diminishes tongue morbidity while preserves good facial reanimation. The goal of the present ...
