Frictional Forces on Screws01:17

Frictional Forces on Screws

1.7K
Screws are characterized by a helical ridge known as a thread wrapped around a cylindrical shaft. They are commonly used as fasteners to hold objects together or to transmit power and motion in machines. One type of screw that is particularly useful for transmitting power is the square-threaded screw.
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...

Self-Locking Screw

2.6K
A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.

Area of Science:

  • Craniofacial surgery
  • Orthognathic surgery
  • Maxillary osteotomy

Background:

  • Traditional Le Fort I osteotomy fixation commonly employs plates and screws along the canine and zygomatic pillars.
  • Variations in fixation techniques for high maxillary osteotomies are less frequently reported in recent literature.

Observation:

  • A 20-year-old patient with Crouzon syndrome presented with severe maxillary hypoplasia, mandibular prognathism, and a Class III facial pattern.
  • The patient underwent orthognathic surgery involving a high Le Fort I osteotomy.

Findings:

  • A modified fixation technique using eight positional screws was employed for the high maxillary osteotomy.
  • This approach offers an alternative fixation method for specific clinical scenarios in complex maxillary advancement.

Implications:

  • The described technique provides a potentially valuable alternative for fixation in high maxillary osteotomies.
  • This variation may enhance surgical outcomes in patients with significant midface hypoplasia and syndromic conditions like Crouzon syndrome.
