Summary
This case report introduces a novel tenon-mortise connector for pediatric dental space maintainers. This design facilitates passive eruption and alignment of young permanent teeth after tooth loss.
Area of Science:
- Dentistry
- Pediatric Dentistry
- Prosthodontics
Background:
- Tooth loss in children necessitates space maintenance until permanent restoration.
- Odontogenic keratocysts can lead to significant tooth loss requiring specialized appliances.
- Fixed functional space maintainers are crucial for preserving arch integrity in growing patients.
Observation:
- A 13-year-old patient lost mandibular premolar and molar due to odontogenic keratocyst removal.
- A fixed functional space maintainer was designed to bridge the edentulous space.
- The appliance featured band retainers connected to pontics using a tenon-mortise nonrigid connector.
Findings:
- The tenon-mortise connector allowed limited passive eruption and alignment of adjacent young permanent teeth.
- Nickel-chromium alloy was used for the casting, with ceramic-layered pontics.
- This design addressed the need for space maintenance during growth before definitive rehabilitation.
Implications:
- This nonrigid connector design offers a potential improvement for pediatric space maintainers.
- It may enhance functional outcomes and tooth alignment in growing dentitions.
- Further research could explore the long-term efficacy and adaptability of this connector type.

01:23Types of Building Separation Joints
530
Building separation joints divide large or complex building structures into smaller, discrete units that can move independently. These joints are categorized into three types: volume-change joints, settlement joints, and seismic separation joints.
Volume-change joints address the effects of expansion and contraction due to temperature and moisture variations. They are strategically placed at discontinuities in a building's mass where cracking is most likely and are spaced about 150 to 200...

01:16Self-Locking Screw
2.3K
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.

01:03Structural Joints: Fibrous Joints
3.4K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

01:26Masonry Cavity Walls
1.3K
Cavity walls feature a hollow space between the outer and inner wythes, connected only by corrosion-resistant metal ties. When water seeps through the outer wythe, it descends within this cavity, intercepted by flashing and eventually exiting through weep holes. To enhance moisture resistance, the inner wythe's cavity side often receives damp-proofing, doubling as an air barrier. The cavity can also house insulation to mitigate heat transfer.

01:15Posttensioned Masonry Walls

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...

In wood construction, fasteners are essential for securing components together, with the connection strength largely dependent on the direct bearing between members. Various types of fasteners are employed, each suited to specific applications and structural requirements.
Nails are the most common fasteners, consisting of sharp-pointed metal pins that are driven into wood using a hammer or a mechanical nail gun. They come in a variety of diameters, heads, and lengths. Nailing techniques include...
