Bone screws and plates in orthognathic surgery

International Journal of Oral Surgery, 1982
The almost universal use of bone plates and screws in orthognathic surgical procedures is surveyed. Based upon considerable personal experience, it is advocated that this technique should be used for better stabilization of the fragments, leading to faster bone healing and therefore to less relapse.

Stripping Torque Model for Bone Screws

IFAC-PapersOnLine, 2021
: Correct torquing of bone screws is critical for positive patient outcomes in orthopaedic surgery. Under-or over-tightening screws can lead to thread stripping or screw loosening, leading to implant/fixation failure and potential tissue damage or ...

Success of infrazygomatic crest bone screws: patient age, insertion angle, sinus penetration, and terminal insertion torque.

American Journal of Orthodontics and Dentofacial Orthopedics, 2022
INTRODUCTION The aim of this study was to assess the 6-month survival (success) rate for infrazygomatic crest (IZC) bone screws relative to patient age, insertion angle, sinus penetration, and terminal insertion torque.

Orthodontic bone screws: A quick update and its promising future.

Orthodontics & craniofacial research, 2020
Orthodontic bone screws (OBSs) provide intraoral anchorage by penetrating oral mucosa and seating firmly in basilar bone (BB). Retromolar (prosthetic-type) implants introduced the extra-alveolar (E-A) concept for BB anchorage to move teeth throughout the

Comments on bone screws

Techniques in Orthopaedics, 1991
Metal bone screws are a fundamental element of fracture fixation. Screws are described by their thread diameter, thickness of the root of the screw, and pitch. Bone screws are inserted by first making a pilot hole. When screws are used to coapt or lag bone, then a channel has to be drilled the same diameter as the threads. Cannulation of a screw allows

Alendronate Inhibits Bone Resorption at the Bone-screw Interface

Clinical Orthopaedics & Related Research, 2005
In the current study, we investigated whether the systemic administration of alendronate, a third-generation bisphosphonate, suppressed the loosening of screws at the bone-screw interface. We systemically administered alendronate to rats fitted with external fixators.
