Phases of Tx & Wire Sequence
TLDRThis informative video script delves into the intricacies of orthodontic treatment, outlining the three key phases: alignment, space closure, and detailing. It explains the use of different orthodontic wires, such as nickel titanium and stainless steel, and their roles in achieving straight, well-aligned teeth. The script also details the bracket system, including various bracket types and their specific features. The process of transitioning from crooked teeth to a perfectly aligned smile is clearly mapped out through the sequence of wires and treatment stages, highlighting the meticulous work involved in orthodontics.
Takeaways
- 🦷 Orthodontic treatment consists of three phases: alignment, space closure, and detailing.
- 🔄 Brackets have different designs, such as second premolar to second premolar with four tie wings, and molars with bondable tubes.
- 📏 The height of the bracket slot is crucial, with the office using an 018 slot, which is .018 inches tall.
- 🌙 Nickel titanium wires are used in the initial phase for their shape memory and flexibility, helping to align crooked teeth.
- 🔩 Stainless steel wires are more rigid and can accept bends, making them suitable for the final detailing phase of treatment.
- 🔄 TMA or beta titanium wires are a hybrid, combining the flexibility of nickel titanium with the bending capability of stainless steel.
- 📈 The wire sequence starts with a .014 nickel titanium wire, followed by a .016 nighttime wire for additional force.
- 🏠 The 17x25 nighttime wire corrects torque and uprights the teeth, a slow process involving moving the entire root through the bone.
- 🔧 The final wire, a 16x22 stainless steel wire, allows for detailed adjustments and fine-tuning of the teeth's alignment.
- 🔄 During the space closure phase, elastics and springs are used on the 17x25 nighttime wire to close gaps and correct the bite.
- 🎯 The detailing phase focuses on achieving the perfect alignment, with adjustments made to individual teeth as needed.
Q & A
What are the main components of a bracket used in orthodontic treatment?
-The main components of a bracket include the bracket slot where the wire goes, four tie wings that surround the corners of the bracket slot, and for the canine and premolars, a hook for elastics.
What type of bracket is used for molars in orthodontic treatment?
-Molars use bondable brackets which are tube-like structures. They have a bondable base like other brackets, but instead of an open slot, they are usually a tube.
What are the three phases of orthodontic treatment?
-The three phases of orthodontic treatment are alignment, space closure with elastic wear, and detailing for final adjustments and perfect alignment.
What is the significance of the .018 slot size in orthodontic brackets?
-The .018 slot size refers to the height of the bracket slot, which is .018 inches tall or 18 thousandths of an inch. This size is used to accommodate the orthodontic wire and is standard in the office mentioned in the script.
How does a nickel titanium wire contribute to the initial alignment of crooked teeth?
-Nickel titanium wires are very flexible and have great shape memory. They are used in the initial phase of treatment to slowly pull the crooked teeth into a uniform arc shape.
What are the differences between a round and a rectangular nighttime wire?
-A round nighttime wire is flexible and made of nickel titanium, used for initial alignment. A rectangular nighttime wire has a rectangular cross-section and is used to correct the torque of the teeth during the detailing phase.
What is the role of stainless steel wire in orthodontic treatment?
-Stainless steel wires are more rigid than nickel titanium wires and can accept and hold bends. They are used during the final detailing phase of treatment for precise adjustments.
How does the TMA or beta titanium wire differ from other orthodontic wires?
-TMA or beta titanium wires are a hybrid, being more flexible than stainless steel but able to accept bends like it. They are used by some offices for the detailing or finishing phase of treatment.
What is the typical wire sequence used to progress from crooked teeth to straight teeth in orthodontic treatment?
-The typical wire sequence starts with a .014 nighttime wire for initial alignment, followed by a .016 nighttime wire, then a .017 x .025 nighttime wire for torque correction, and finally a .016 x .022 stainless steel wire for detailing and final adjustments.
How long does each phase of orthodontic treatment typically last?
-The alignment phase usually lasts about two months with each wire, the space closure phase varies depending on the case, and the detailing phase is the final step to achieve perfect alignment.
What are the key movements achieved by each type of wire in the treatment sequence?
-The .014 and .016 nighttime wires help in initial alignment and straightening. The .017 x .025 nighttime wire corrects torque. The .016 x .022 stainless steel wire is used for detailing and final adjustments.

🦷 Introduction to Orthodontic Treatment and Brackets
This paragraph introduces the video's focus on the parts of a bracket, the basic phases of orthodontic treatment, and the wire sequence used to transition from crooked teeth to a straight alignment. It explains the components of different types of brackets, such as the slot for the wire, tie wings, and hooks for elastics on specific teeth. The paragraph also outlines the three phases of orthodontic treatment: alignment, space closure with elastic wear, and detailing for final adjustments. It introduces the concept of using nickel titanium wires for their shape memory and flexibility, which are used in the initial phase of treatment to straighten the teeth.
🔄 Understanding Orthodontic Wire Sequence and Types
The second paragraph delves into the specifics of the wire sequence used in orthodontic treatment. It begins with an explanation of the 014 nighttime wire, which is the first wire used in the alignment phase to start straightening the teeth. The paragraph then describes the progression to a 016 nighttime wire for additional force, followed by a 17x25 nighttime wire for correcting torque. The detailing phase is addressed with the use of a 16x22 stainless steel wire, which allows for precise bending to compensate for any remaining misalignment. The paragraph also touches on the use of different types of orthodontic wires, such as stainless steel and TMA/beta titanium, and their roles in various phases of treatment.

Highlights
The video discusses the parts of a bracket and the phases of orthodontic treatment.
Brackets for premolars have four tie wings and a slot for the wire, while canines and premolars have hooks for elastics.
Molar brackets are tube-like and can be convertible, with the video's office using standard tubes.
Brackets have different slot sizes, with the office using an 018 slot.
Orthodontic treatment is carried out in three phases: alignment, space closure, and detailing.
The first phase involves using flexible wires for initial alignment of teeth.
The second phase focuses on space closure and bite correction with elastic wear.
The third phase, detailing, involves making final adjustments for perfect alignment.
Three basic types of orthodontic wires are discussed: nickel titanium, stainless steel, and TMA/beta titanium.
Nickel titanium wires are flexible and have great shape memory, used for initial alignment.
Stainless steel wires are more rigid and used for the final detailing phase.
TMA/beta titanium wires are a hybrid, flexible like nickel titanium but can accept bends like stainless steel.
The wire sequence starts with a 014 nighttime wire for initial straightening.
An 016 nighttime wire is used next for further alignment and straightening.
The 17x25 nighttime wire is used to correct torque and upright the teeth.
Finally, a 16x22 stainless steel wire is used for detailing and perfecting the alignment.
Space closure is achieved by using elastic chains or centrali springs on the 17x25 nighttime wire.
