- Frankel's functional regulator (FR) is a functional appliance developed by Rolf Frankel to correct malocclusions by expanding the oral space.
- It works by altering muscle function through the use of acrylic shields and wires rather than directly moving teeth.
- Studies on the FR have found it effective in correcting Class II malocclusions through dentoalveolar changes rather than true skeletal changes. It induces downward and forward mandibular rotation.
- Modifications to the FR include capped designs, modifications to address vertical maxillary excess, and hybrid designs combining FR and activator elements. Comparative studies found it and twin block effective but with different dentoalveolar effects.
1. The document discusses features, etiology, and treatment of anterior open bite and deep bite. It describes skeletal, dental, soft tissue, and growth features of high and low angle cases.
2. Cephalometric measurements used to assess open bite and deep bite tendencies are described, including overbite depth indicator, Jarabak ratio, and UAFH-LAFH ratio.
3. Causes of open bite discussed include habits, enlarged adenoids, and posterior rotation of the mandible. Deep bite causes include class II skeletal pattern and anterior rotation of the mandible.
The document summarizes the Royal London Space Planning approach for orthodontic treatment planning. The approach involves assessing six factors that impact the space required for treatment: crowding, occlusal curves, arch width, incisor positioning, tooth angulation, and tooth inclination. Scores are recorded for each factor to quantify the overall space needed. The approach aims to ensure a systematic treatment plan, determine if objectives are achievable, anticipate anchorage issues, and improve informed consent.
The document discusses the Royal London Space Planning process for orthodontic treatment planning. The process occurs in two stages: 1) assessing the initial space required to achieve treatment objectives, and 2) integrating space analysis with consideration of how other treatment procedures may affect space. These procedures include tooth enlargement or reduction, extractions, replacing absent teeth, and molar movement. The analysis records any additional space created or used. The outcome is determining if treatment objectives can be attained with the planned mechanics.

This document discusses factors to consider in determining whether extractions are needed for borderline orthodontic cases. It outlines various dental measurements like dental discrepancy, curve of Spee, and irregularity index that help assess the need for extraction. It also discusses cephalometric measurements of the jaws, teeth positions and soft tissue profiles. The effects of extractions versus non-extraction treatments on achieving functional occlusion and facial esthetics are weighed. Formulas are presented to aid extraction decisions for Class III borderline cases. The conclusion emphasizes that experience, proper malocclusion correction, facial aesthetics and stability must all be considered, not just dental spacing alone.
This presentation describes the COGS analysis of patient's cephalogram who is in need of an orthognathic surgery. Hope it helps Orthodontists and Oral and Maxillofacial surgeons.

orthodontic correction of occlusal plane canting PART 3Maher Fouda
The document describes using a rhythmic wire system with miniscrews to correct occlusal plane canting. It details a biomechanical system called "rhythmic wire" consisting of miniscrews and intrusion/extrusion wires. The system is used in two patient cases to intrude maxillary teeth and extrude mandibular teeth, correcting the cant without surgery. Placement of miniscrews and intrusion/extrusion wires between teeth guided vertical movement and transpalatal/lingual arches controlled tipping. Both patients' occlusal canting was successfully corrected in under 2 years with this customized orthodontic treatment.
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.
Orthodontic correction of occlusal plane canting part 1 MaherFouda1
This document discusses the orthodontic correction of occlusal plane canting. It begins by explaining that occlusal plane canting is challenging to correct without surgery as it requires precise control of tooth positioning. With the advent of skeletal anchorage, true intrusion of molars is now possible, allowing correction of occlusal plane canting without surgery in some cases of mild facial asymmetry. The document then provides details on diagnosing and measuring occlusal plane canting, as well as biomechanical principles and techniques for correcting canting orthodontically using skeletal anchorage like mini-implants.

The Dynamax System is a new orthopedic appliance designed to treat skeletal Class II malocclusions. It has an upper removable component and a lower component that can be either removable or fixed. The appliance uses vertical springs on the upper component to engage "shoulders" on the lower component and advance the mandible into a protrusive position. It is constructed simply and can progressively advance the mandible in small increments to encourage growth. A case study showed that treatment with the Dynamax appliance for 18 months reduced a patient's ANB by 4 degrees. The Dynamax provides an efficient way to correct skeletal Class II malocclusions at any stage of dental development.
The pendulum appliance uses acrylic and springs to deliver continuous force from the palate to the upper molars, producing distal movement without affecting other teeth. It is fabricated with acrylic covering springs that extend to molar bands. Springs are activated in 3-week intervals to monitor distalization over 4 months before stabilizing molars. The appliance effectively treats Class II malocclusions without extractions through distal molar movement.
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.
The document discusses the Peer Assessment Rating (PAR) index, which is used to evaluate orthodontic treatment outcomes. It was developed through meetings of experienced orthodontists who formulated the index using over 200 pre- and post-treatment cases. The PAR assigns scores to various components like anterior teeth alignment, overjet, overbite, and midline to provide a cumulative score. Treatment results are graded as greatly improved, improved, or no different based on the reduction in PAR scores from pre- to post-treatment. The document then provides detailed descriptions and scoring criteria for each component of the PAR index.
This document describes the Frankel appliance, a type of removable functional orthodontic appliance developed in the 1950s. It summarizes the four main types of Frankel appliances (FR I-IV) and their indications. The key components and mechanisms of action of the FR I appliance are described in detail, including its acrylic parts (buccal shields, labial pads, lingual shield) and how they work to correct muscle posture and spatial disorders through forces on the periosteum.

Functional appliances utilize the natural forces of the orofacial musculature to produce skeletal and dental changes. They are based on Moss's functional matrix theory which proposes that muscles and glands influence bone growth. Functional appliances can be active or passive and produce orthopedic, dentoalveolar, and muscular changes through forces of compression, elimination of restrictive influences, and mandibular repositioning. Common functional appliances discussed in the document include Bionators, Twin-Blocks, Herbst, Frankel Regulator, and Jasper Jumper. They vary in their mode of action, indications, advantages, and disadvantages.
This document discusses functional appliances used in orthodontic treatment. It describes the advantages and disadvantages of functional appliances, how they work to produce orthopedic, dentoalveolar and muscular changes, different types of functional appliances including activators and Frankel regulators, and guidelines for use and patient instruction.
Frankles appliance Is a myofunctional appliance
Functional appliance are removable or fixed appliances that aim to utilize eliminate or guide the forces arising from muscle function,tooth eruption and growth inorder to alter skeletal and dental relationship
The Frankel functional regulator is a removable orthodontic appliance developed by Dr. Rolf Frankel to effect changes in the jaw relationship during mixed and early permanent dentition. It consists of upper buccal shields, lower lip pads, and wires. The shields and pads act to change muscle function and guide jaw growth. Indications include Class II malocclusions with a retruded mandible. Contraindications include severe crowding. The appliance aims to correct jaw positions through muscle adaptation and differential tooth eruption guidance between the arches.
The document discusses different types of functional appliances used in orthodontics including simple functional appliances like lip bumpers and oral screens, as well as more complex removable appliances like the Frankel regulator, Bionator, activator, and twin block. It describes the indications, contraindications, components, and mechanics of several commonly used functional appliances.

The document discusses the Frankel functional regulator, an orthodontic appliance developed by Rolf Frankel in 1961. It consists of a skeletonized oral shield with buccal shields, lip pads, and wires. The appliance aims to harness natural muscle forces to guide jaw development without contacting underdeveloped areas. It works by stretching tissues with the shields and pads to encourage bone growth, while allowing free tongue movement. The document outlines the components, indications, contraindications, advantages and disadvantages, and clinical use of the Frankel appliance.
This document discusses functional orthodontic appliances. It defines functional appliances as loose, removable intra-oral devices that alter muscle forces against teeth and craniofacial structures. It then discusses several types of functional appliances including twin blocks, bionators, activators, and oral screens. For each appliance, it describes the history, design, mode of action, indications, and effectiveness. The document provides detailed information on how functional appliances work to influence soft tissues, muscles, teeth, and jaw skeletons to correct malocclusions.
This document provides an overview of functional orthodontic appliances. It begins by explaining that orthodontic appliances can be either removable, fixed, or functional. Functional appliances work by utilizing forces from the muscles rather than having an active component themselves. They are often removable and used to treat Class II and Class III malocclusions in growing patients. Common functional appliances discussed include lip bumpers, oral screens, twin blocks, Andresen activators, Bionators, Herbst appliances, and Frankel regulators. The document concludes by discussing considerations for choosing a functional appliance and their management.
This document provides an overview of myofunctional appliances used in orthodontics. It discusses how they work to modify skeletal discrepancies by harnessing natural muscle forces. Different types of appliances are described, including activators, Frankel regulators, and Twin Blocks. Key factors in case selection and successful treatment outcomes with these appliances are highlighted, such as patient age and cooperation. The document also reviews concepts like Moss's functional matrix theory and how appliances can guide dental changes and bone growth. Contraindications and factors maximizing success are outlined.
This document provides an overview of the current status and use of Twin Block appliances in orthodontic treatment. It discusses the original Twin Block design developed by Clark and modifications that have been made. It describes how Twin Block appliances can be used to treat Class II and Class III malocclusions. Details are provided on bite registration, appliance design for different malocclusions, and clinical management over an active treatment phase and retention phase.

Use of modified tooth forms in complete denture occlusion / dental implant...Indian dental academy
This document discusses dental occlusion concepts and philosophies for complete dentures. It introduces key terms like physiologic occlusion and defines different occlusion schemes like balanced articulation and monoplane articulation. The document discusses advantages and disadvantages of using anatomic versus non-anatomic teeth for complete dentures. It also outlines requirements for maintaining denture stability, such as balanced occlusal contacts and control of horizontal forces. The goal of occlusion for complete dentures is to re-establish the homeostasis of the masticatory system disrupted by edentulism.

The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
8. Perioral muscles had restraining effect on
dental arches
Insertion of appliance –expands capsule and
allows for new functional adaptation of
muscles
Activator – ‘ push from within’
FR – ‘ought to be matrix’
All activities of oral cavity – muscle training
FRANKEL’S PHILOSOPHY
9. FRANKEL’S PHILOSOPHY
Buccal shields and lip pads exert
periosteal pull
exp not verified this effect
Graber (1988) exp- on primates
showed that this effect is temporary
10. FRANKEL’S PHILOSOPHY
The mechanical effect of the appliance
directed to the capsular matrix and not
to teeth / alveolar process.
MOYERS
‘altering the condition that determine the pattern of
occlusal development rather than altering the
occlusion directly.’
27. Upper lingual wire

Characterized by diminished
volume of the superior part of
the oro-facial capsule
Related to structural and
postural imbalance of
muscles
Lingual volume not to be
diminished
75. FR in the treatment of class 3
Expansion of
upper oral
space
Tongue
space not
diminished
76. FR in the treatment of
class 3
Septo premaxillary ligament pull
translates upper incisors bodily
FR3 promotes max basal bone
development and translates maxilla
forward
Appliance should not be locked in the
maxilla by wires
77. FR in the treatment of skeletal
open bites
Aimed at correcting the
poor lip valve
mechanism.
Marked activity of
temporalis and
masseter when lips are
closed
Acc to Frankel tongue
thrust is compensatory

specifically and individually tailored to
exploit the natural process of growth
and development
1. Bite planes
2. Shields and screens
3. Construction and working bite
93. Modified Fr with continuous buccolabial shield
and palatal acrylic support- haynes ajo 1986
To eliminate lip
trap
No pressure on
the gingival
dentoalveolar
tissues
95. N.R.E Robertson AJO 1983
12 cases with FR2 and FR3 using cephs
and conclude the principle changes were
dentoalveolar
MC NAMARA AJO 1984
3 adult patients with class 2 malocclusion
with mandibular retrusion
Length of mandible not increased but
vertical dimensions increased
Adaptation minimal not sufficient to
overcome malocclusion
96. FACIAL GROWTH DURING
TREATMENT WITH FR APPLIANCE
Leth Nielsen AJO 1984
10 pts treated with FR showed maxilla
retrognatic
No indication that mandibular growth was
promoted
Changes more in vertical plane
Not necessarily improved the profile
97. Skeletal and dental changes following FR
therapy on class II patients
MC NAMARA AJO 1985
100 pts treated for 24 months and
compared with controls

open bite
ELIT ERBAY AJO 1995
20 treated and 20 controls
Useful in treatment
Diminished AFH ,growth rate of AFH (3.9
mm)decreased ,& PFH increased (4.5 mm).
Caused forward and upward rotation of
mandible
Reduction in mandibular plane angles i.e Sn-
GoMe,AnsPns-GoMe
100. Frankel-post vestibular shields caused
inferior translation of mandible,growth at
condyle increase in ramal length
Anterior part of mandible rotated upward
because of the lip seal
Erbay’s study noted FR inhibited
posteriors and improved the axial
inclination of U1
102. FR Vs twin block
toth/mc namara AJO 1999
4O PTS WITH TWIN BLOCK AND FR COMPARED
TO CONTROLS
Results
Increase in mandibular length
Twin block – 3mm > controls
