Open Coil Spring, Closed Coil Spring, & Kobie Ties
TLDRThe video script provides a detailed guide on orthodontic procedures involving different types of springs. It explains the use of open coil springs for creating space and closed coil springs for maintaining it, as well as the application of Kobe ties or hooks for securing brackets without posts. The instructions include step-by-step demonstrations on how to properly position and secure these orthodontic components to achieve optimal results in teeth alignment.
Takeaways
- π The open coil spring is used to create space between teeth, particularly when there isn't enough room for alignment.
- π To activate an open coil spring, it should be compressed by one bracket's width to create the necessary force for pushing teeth apart.
- π§ Placing an open coil spring involves sliding it onto the wire outside the patient's mouth, aligning it with the archwire's midline, and securing it with steel ties to prevent rotation.
- π¦· The closed coil spring is used to maintain space between teeth, preventing them from moving closer together during treatment.
- π When applying a closed coil spring, it should be positioned flush between brackets to ensure no space closes unintentionally.
- ποΈ O ties are used to hold the archwire in place while positioning the spring, ensuring proper alignment and tension.
- π The Kobe tie or hook is a specialized tool used to provide a post for elastics on anterior brackets that lack them.
- π To apply a Kobe tie, it is pinched and bent into place on the archwire beneath where the wire slot would go, ensuring a tight and secure fit.
- π The ligature director is a tool that aids in compressing the open coil spring between brackets, facilitating easy placement and activation.
- βοΈ Excess wire and ties should be trimmed and tucked under the archwire to avoid causing discomfort or irritation to the patient.
- π If adjustments are needed after the wire is in place, such as adding a Kobe tie, the wire does not need to be completely untied, allowing for minor modifications.
Q & A
What is the primary purpose of an open coil spring in orthodontics?
-The primary purpose of an open coil spring is to create space between teeth, especially when there isn't enough room for a tooth to align properly, such as in cases where brackets are already placed.
How is an open coil spring activated in orthodontic treatment?
-An open coil spring is activated by compressing it and then attaching it to the archwire. This compression creates a force that pushes the teeth apart, opening up space for the misaligned tooth.
What is the correct way to place an open coil spring onto the wire?
-To place an open coil spring, it should be slid onto the wire outside the patient's mouth. The midline on the wire should be aligned with the archwire, and the spring should be positioned correctly before securing it with a steel tie on either side to prevent tooth rotation.
What is the difference between an open coil spring and a closed coil spring?
-An open coil spring has open coils and is used for pushing teeth apart to create space, while a closed coil spring has closed coils and is used for holding space, preventing teeth from moving closer together.
How do you prevent an open coil spring from rotating the teeth during orthodontic treatment?
-To prevent rotation, steel ties are used on either side of the open coil spring. These ties hold the spring steady and counteract the rotational force, ensuring that the teeth do not rotate as the spring pushes them apart.
What is the function of a Kobe tie or Kobe hook in orthodontics?
-A Kobe tie or Kobe hook is used in orthodontics to provide a post for attaching elastics on anterior brackets that do not have posts. It is a steel tie with a loop at the end, allowing for the secure placement of elastics where needed.
How do you attach a Kobe tie or Kobe hook to the archwire?
-To attach a Kobe tie or hook, it is pinched with the fingers and then wrapped around the archwire with a slight bend. The bend should be positioned at the disto-gingival corner of the bracket, and the tie should be cinched tightly to ensure it does not loosen over time.
Can a Kobe tie or Kobe hook be added after the archwire is already in place?
-Yes, a Kobe tie or hook can be added after the archwire is in place. The excess wire is trimmed, and the tie is threaded under the archwire and then tightened using a closed mouth pliers or similar tool.
Why is it important to ensure the Kobe tie or hook is tight and secure?
-It is important to ensure the Kobe tie or hook is tight and secure because it helps maintain the correct positioning of the elastic and prevents it from loosening over time, which could affect the effectiveness of the orthodontic treatment.
What should you do if the Kobe tie or hook becomes loose during treatment?
-If the Kobe tie or hook becomes loose, you should tighten it by grabbing hold of it and winding it up slightly. However, care should be taken not to over-tighten it, as this could break the steel or dislodge the bracket.
How do you maintain the proper positioning of the steel ties and coils during orthodontic treatment?
-To maintain the proper positioning, the steel ties and coils should be regularly checked during orthodontic appointments, and any adjustments or replacements should be made as necessary. The orthodontist or dental assistant will ensure that all components are securely in place and functioning correctly.
Outlines
π¦· Open Coil Spring Placement
This paragraph explains the process of placing an open coil spring in orthodontics. The open coil spring is used to create space between teeth, especially when there isn't enough room for a tooth to align properly. The steps include activating the spring by one bracket's width, attaching it to the wire outside the patient's mouth, aligning it with the archwire's midline, and securing it with steel ties to prevent tooth rotation. The open coil spring pushes the teeth apart, creating space for the misaligned tooth, which can then be bracketed once there is enough room.
π Closed Coil Spring Application
The second paragraph discusses the application of a closed coil spring, which is used to maintain space between teeth. Unlike the open coil spring, the closed coil spring's coils touch each other and are ideal for holding space rather than pushing teeth apart. The paragraph explains how to slide the closed coil spring onto the wire, ensuring it fits snugly between two brackets and is touching both sides to prevent space closure. The use of an O-tie to hold the wire in place and the process of clipping and tucking excess wire is also described. The closed coil spring is particularly useful when a chain is being used to close spaces in other parts of the mouth, but certain spaces need to be preserved.
π Kobe Ties/Hooks: Usage and Installation
This paragraph focuses on the use of Kobe ties or hooks in orthodontic treatment. Kobe ties are similar to steel ties but have a small loop at the end, which serves as a hook. They are used on anterior brackets that lack posts for elastic attachments. The paragraph details the process of pinching and bending the Kobe ties, positioning them on the lower or upper front teeth, and securing them tightly to prevent movement. The importance of winding the tie up without any slack and tucking the excess down in a way that it doesn't loosen over time is emphasized. The Kobe hooks can be added after the archwire is in place if needed, and the paragraph explains how to thread and tighten them under the wire without having to untie the entire setup.
βοΈ Trimming and Securing Wire
The final paragraph covers the steps of trimming excess wire and securing it properly. After placing the Kobe ties or hooks, any extra wire is trimmed off, and the remaining portion is threaded under the wire. The paragraph explains how to use a closed mouth pliers to grab and tighten the wire, ensuring a secure fit without slack. The importance of trimming the excess wire to the appropriate length and tucking it down in a way that prevents it from unwinding or causing issues later is highlighted. The process allows for adjustments and re-tightening if the wire becomes loose over time.
