Tent screws: Predictable guided bone regeneration

open access: yesJournal of Indian Society of Periodontology, 2023
Abstract Bone regeneration of large maxillary and mandibular alveolar ridge defects is clinically challenging. Various techniques have been described for the reconstruction of these deficiencies before implant placement. The tent screw-pole technique is one of the effective methods available for clinicians to perform the predictable ...

Biomechanical evaluation of the fixation strength of lumbar pedicle screws using cortical bone trajectory: a finite element study.

open access: yesJournal of Neurosurgery : Spine, 2015
OBJECT Cortical bone trajectory (CBT) maximizes thread contact with the cortical bone surface and provides increased fixation strength. Even though the superior stability of axial screw fixation has been demonstrated, little is known about the ...
