Summary
This study introduces a novel spike expander for correcting transverse maxillary deficiency. This innovative appliance offers easier fabrication, improved hygiene, and reduced soft-tissue irritation, maximizing skeletal expansion.
Area of Science:
- Orthodontics
- Craniofacial Surgery
Background:
- Transverse maxillary deficiency requires effective correction methods.
- Traditional expanders can cause discomfort and dental side effects.
Observation:
- A new expander design utilizes spike screws and an expansion screw.
- The appliance is fabricated without an acrylic plate, enhancing hygiene and comfort.
Findings:
- The spike expander facilitates easier maxillary widening with reduced direct force on teeth.
- It promotes parallel alveolar expansion, minimizes dental tipping, and lessens soft-tissue irritation.
- Simultaneous teeth alignment is possible as the expander does not contact teeth.
Implications:
- This design offers a simpler, more effective treatment for transverse maxillary deficiency.
- It presents a potentially superior alternative to conventional maxillary expanders.
- The appliance's ease of fabrication and removal simplifies the orthodontic process.

01:16Self-Locking Screw
2.7K
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.

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.

01:15Thin-Walled Hollow Shafts
661
In analyzing a thin-walled hollow shaft subjected to torsional loading, a segment with width dx is isolated for examination. Despite its equilibrium state, this segment faces torsional shearing forces at its ends. These forces are quantitatively described by the product of the longitudinal shearing stress on the segment's minor surface and the area of this surface, leading to the concept of shear flow. This shear flow is consistent throughout the structure, indicating a uniform distribution of...

01:20Normal Strain under Axial Loading
1.5K
Normal strain under axial loading is an important concept in the field of mechanics of materials. Axial loading implies the application of a force along the axis of a material, like a column or bar. This force can either compress or stretch the material. In the context of axial loading, normal strain is the deformation experienced by the material in the direction of the loading force. It's calculated as the change in length divided by the original length of the material. This unitless ratio...

01:15Posttensioned Masonry Walls
575
Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...

Steel sections can be joined together through various fastening techniques including riveting, bolting, and welding, each suitable for different structural requirements and conditions.
Rivets are cylindrical steel fasteners with a specially designed head. During application, rivets are heated until white-hot and then inserted through pre-drilled holes in the steel sections. A pneumatic hammer is used to shape the exposed end into a second head, securing the sections together.
Bolting is another...
