Space closure in orthodontic treatment can be done with either segmented or sliding mechanics. Segmented mechanics allow for frictionless tooth movement while sliding mechanics involves overcoming friction. There are several methods for space closure including elastic chains, coils, and loops. Elastic chains provide light constant forces but can lose up to 60% of their force over time. Combining chains with open coils can provide greater force and faster space closure of around 1.5-2mm per month, though it may cause more root resorption. Proper use of anchorage and heavy archwires can control unwanted tooth movement during space closure.

A 12-year-old girl presented with a tongue thrusting habit. Her medical history was unremarkable and it was her first dental visit. On examination, she was in the permanent dentition stage with a Class I molar relationship and some occlusal prematurity. The treatment plan was to fix a modified Blue Grass appliance to teeth #16 and #26 to address the tongue thrusting habit.
The document provides information on the history and development of the Andresen activator. It describes:
1. How the activator was originally developed in 1909 by Viggo Andresen to treat his daughter's Class II malocclusion.
2. How the activator works to correct malocclusions through guiding the mandible into a forward position using interocclusal acrylic planes and muscular forces.
3. The controversies around the different construction bite concepts and theories on how the activator stimulates skeletal adaptation.
4. The guidelines for taking the construction bite and fabricating the activator, including registering the bite, articulating models, wiring, and trimming.

The document discusses the use of an extrusion arch to correct an anterior open bite. It describes how an extrusion arch creates a one-couple force system, applying an extrusive force to the anterior teeth and an intrusive force plus tip-forward moment to the posterior anchorage. It notes that seating elastics are needed to control the unwanted tipping, and presents a case report where miniscrew anchorage was used instead to prevent tipping while the arch closed an open bite over multiple months.
This document provides an overview of functional appliances used in orthodontic treatment. It begins with an introduction to functional appliances and their use in guiding natural forces to correct morphological abnormalities. It then covers classifications of functional appliances, how cephalometric analysis is used to assess patients, and descriptions of common appliances like the activator, bionator, and twin-block. The document discusses how functional appliances can correct Class II and III malocclusions by influencing facial growth. In under 3 sentences.
This document discusses strategies for reducing overjet in orthodontic treatment. It presents four examples of patients requiring overjet reduction and proposes treatment plans for each. The key points covered are the four main ways to reduce overjet: moving the lower incisors forward, moving the upper incisors back, moving the mandible forward, and limiting maxillary growth. Factors like molar relationship, amount of extraction, and facial angle are considered for determining the best mechanics in each case.

determinate vs indeterminate force systemKumar Adarsh
This document discusses force systems in orthodontics. It describes determinate and indeterminate force systems, with determinate systems providing better control of forces and moments. One-couple systems are created using a cantilever spring or auxiliary arch wire tied to a tooth at one end. Two-couple systems are created when an arch wire is tied into brackets on both ends. Common applications of one and two-couple systems include intrusion/extrusion arches and lingual arches. Segmented arch mechanics allow precise control but require more wire bending compared to continuous arch wires.
This document discusses the use of headgear to correct Class 2 skeletal problems. It defines headgear as an extraoral orthopedic appliance used to restrain downward and forward growth of the maxilla. It describes the components, types, and effects of different headgear, including high pull/occipital headgear, low pull/cervical headgear, and combipull/straight headgear. Guidelines are provided for headgear selection, force magnitude and duration, limitations, uses, and maintaining correction following removal.
The document discusses using bite ramps or bite turbos in orthodontic treatment to correct deep overbites and curves of Spee. It provides instructions on how to make and place bite ramps using light cure material. Bite ramps are bonded to the palatal surfaces of maxillary central incisors. The ramps can be extended lingually if needed. Bite ramps are a useful orthodontic device to correct deep overbites and allow bonding of lower anterior brackets which may otherwise not be possible.
This document discusses various types of intrusion arches used in orthodontics to correct deep overbites. It begins by defining intrusion and describing the biomechanics and principles involved. It then covers 9 specific intrusion arch designs: 1) Rickett's Utility Arch 2) Tipback Springs 3) Burstone's Continuous Intrusion Arch 4) Burstone's Three Piece Intrusion Arch 5) K-SIR 6) Connecticut Intrusion Arch 7) PG Retraction Spring 8) Translation Arch 9) Lingual Arch for intruding lower incisors. For each type, it provides details on materials, design, and mechanics of intrusion.

Orthodontic tooth movement during space closure can occur through two types of mechanics: segmental/sectional mechanics which do not involve friction, and sliding mechanics which do involve friction between the bracket and archwire. Friction plays a significant role in sliding mechanics. Several methods are used to apply force during space closure, including elastomeric modules, elastomeric chains, and closed coil springs made of materials like stainless steel and nickel titanium. These methods vary in terms of factors like force degradation over time and sensitivity to environmental factors like temperature. Maintaining an optimal force during retraction is important for controlled tooth movement.
The document discusses orthodontic diagnostic procedures, focusing on clinical examination of the dentition and functional analysis. It describes in detail how to examine the dental status, occlusal anomalies, apical bases, and dental midline. It also explains how to determine the postural rest position of the mandible, including different clinical methods and factors that can influence the rest position. Functional analysis examines the temporomandibular joint, swallowing, tongue, speech, lips, and respiration to fully understand the stomatognathic system.
This document provides an overview of orthopedic appliances used to modify maxillary and mandibular growth. It discusses the principles, types (e.g. headgear, facemask), biomechanics, and clinical applications of these extraoral appliances. Key points covered include the magnitudes, durations, and directions of optimal orthopedic forces; the use of headgears like cervical pull, high pull, and combinations; and the goals of growth modification to alter skeletal relationships and avoid surgery.
The document provides an overview of the activator appliance and its modifications. Some key points:
- The activator was developed in the early 1900s as a way to induce functional growth modifications. It works by applying muscle forces to the jaws through light contact between the appliance and teeth.
- There are different types of activators (H-activator and V-activator) depending on the amount of vertical opening and anterior positioning in the construction bite.
- The appliance is indicated for Class II and III malocclusions, open bites, and other functional issues in growing individuals. Contraindications include non-growing patients and severe vertical growth patterns.
- The activator is thought to work

This document discusses biomechanics in orthodontics. It covers physical variables like Newton's laws of motion and terminology used in orthodontics such as vectors, forces, moments, and centers of resistance and rotation. It also discusses forces related variables including magnitude and direction of forces, root surface area, duration of forces, and how drugs can affect the response to orthodontic forces. The relationship between force magnitude, duration, and type of tooth movement is explained. Maintaining an optimal force leads to more efficient movement while excessive forces can damage tissues.
