Management of orthodontic problems with special consideration
1- Management of occlusal relationship problems
2- Management of eruption problems
3- Management of space problems
Management of occlusal relationship problems:
1- Posterior cross bite
2- Eliminate mandibular shift
3- Anterior cross bite
4- Anterior open bite
Management of eruption problems:
1- Over-retained primary teeth:
= when approximately ¾ of the root of permanent tooth id formed, this the time of exfoliation of deciduous teeth or should be removed to prevent bleeding and gingival inflammation that can cause pain
= most over retained primary maxillary molars have buccal or lingual large root intact
= most over retained primary mandibular molars have mesial or distal root still intact and hindering the exfoliation
2- Ectopic eruption:
If both mandibular primary canines are lost, the permanent incisors can tip lingually which reduces the arch circumferences and increase the crowding, a passive lingual arch is used to prevent lingual tipping and maintained adequate space.
N: B: eruption is ectopic when the permanent tooth causes resorption of primary tooth other than that is supposed to replace or resorb the adjacent tooth
= at approximately age of 10 years if the primary canine is not mobile and there is no palpable facial canine, so ectopic eruption should be considered
= ectopic eruption of canine is 1% to 2% and may be lead to: impaction of canine or/and resorption of roots of lateral or central incisors so early diagnosis is very important to prevent root resorption
= if permanent canine is overlap less than half of root lateral incisors so 91% chance to present in normal position
= if the canine overlap more than one half of root of lateral incisors so the chance for normal position is 64%
= if resorption of permanent lateral or central incisors is start so, it should be surgically exposed and use orthodontic procedure to repositioning of it in normal position
3- Supernumerary tooth
4- Delayed eruption of incisors:
When incisors failed to erupt more than one year past the normal eruption time and adjacent one is erupted so start to repositioning:
- Prepare the space for the tooth
- Surgically exposure of the tooth: will erupt rapidly
- If deeply positioned need exposure of crown and reposition by orthodontic treatment using metal chain or elastic chain in heavy wire or overlay Nickel titanium wire to apply force
- Final root positioning is left until the final stage of treatment
5- Ankylosed primary teeth:
= especially primary molars, the permanent tooth fails to resorb the primary one because high bony attachment at cervical region
= this delayed eruption of permanent teeth and deflect from the normal way
= extract the primary tooth and allow normal eruption of permanent one or repositioni

posterior crossbite in primary and mixed dentition etiology and management pedo
1) Posterior crossbite is an abnormal transverse relationship between the upper and lower posterior teeth where the mandibular buccal cusps occlude buccal to the maxillary buccal cusps.
2) Posterior crossbites can be classified based on location, number of teeth involved, unilateral/bilateral involvement, etiology, and extent.
3) Treatment depends on the classification and involves appliances like occlusal equilibrium, coffin springs, cross elastics, W-arches, quad helix, removable appliances, and RME to correct dental, skeletal, or functional crossbites.
Posterior crossbite in_primary_and_mixed_dentition_-_etiology_and_management_...
Posterior crossbite refers to an abnormal transverse relationship between the upper and lower posterior teeth, where the mandibular buccal cusp occludes buccal to the maxillary buccal cusp. Posterior crossbites can be classified based on etiology, number of teeth involved, unilateral/bilateral involvement, and extent. Management depends on whether the crossbite is dental, skeletal, or functional in nature, and involves appliances like Coffin springs, W-arches, quad helix, and rapid maxillary expansion to correct the underlying discrepancy. Early treatment of posterior crossbites is important to allow for proper arch development and prevent future malocclusions.
Eruptive abnormaities in orthodontic movement
This document discusses various types of eruptive abnormalities that can complicate orthodontic treatment outcomes, including tooth impaction, ectopic eruption, transposition, congenitally missing teeth, and supernumerary teeth. Tooth impaction is failure of a tooth to erupt and can be caused by physical impedance or ankylosis. Treatment depends on the specific abnormality and may include extraction, making space, or applying traction forces to guide eruption. Maintaining optimal arch form and function is important despite eruptive abnormalities.
Dental conditions of horses
The document discusses dental terminology and systems used in horses. It describes:
1. The anatomic and Modified Triadan numeric systems used to identify horse teeth. The anatomic system uses letters to denote tooth type, while the numeric assigns each tooth a unique number.
2. Common dental conditions in horses like infundibular necrosis, periodontal disease, periradicular disease, hooks, ramps, tall teeth, and wave mouth.
3. Special dental procedures for performance horses such as wolf tooth removal and reduction of canine teeth.
4. Dental equipment used in examinations and procedures. Extraction and repulsion techniques are also summarized.
Presentation
This document discusses canine impaction, including its definition, causes, classification, diagnosis, and treatment methods. Canine impaction occurs when the tooth fails to fully erupt into the dental arch. The prevalence of maxillary canine impaction ranges from 0.8-2.9% depending on the population. Causes include tooth size-arch length discrepancies and prolonged retention of primary canines. Diagnosis involves radiographs and clinical examination. Treatment may include leaving the impacted tooth in place if there are no issues, surgical exposure and orthodontic alignment, extraction, or prosthetic replacement. Surgical removal requires raising a mucoperiosteal flap and extracting the impacted tooth.
Interceptive orthodontics
Interceptive orthodontics refers to procedures that eliminate or reduce malocclusion in the developing dentition. Local factors that can cause malocclusion include delayed eruption, retained primary teeth, infraocclusion, ectopic eruption, hypodontia, diastema, crowding, and thumb sucking. Treatment for these local factors may include extractions, space maintenance, serial extraction, or appliances to redirect eruption. The timing of interceptive treatment is important to address developing issues before malocclusion worsens.

It provides guidance on management of space issues and timing of extractions in the mixed dentition to facilitate proper alignment of permanent teeth.
cross bite.docx
This document defines and describes cross bites, their causes, types, and treatment approaches. It notes that anterior cross bites are one of the most common malocclusions in children and should be treated immediately to prevent worsening issues. Treatment depends on whether the cross bite is dental, muscular, or osseous in nature. For dental cross bites, options include tongue blades, inclined planes, springs, and screw appliances. For skeletal cross bites, face masks or chin cups may be used. Factors like adequate space and overbite must be considered when selecting a treatment approach. Precise measurements are needed before and after treatment to assess changes.

This document discusses guidelines for extracting teeth in orthodontic treatment. It describes factors to consider when choosing which teeth to extract, such as the amount of crowding, incisor relationship, and anchorage needs. It provides guidance on when extraction of specific teeth is appropriate, such as extracting premolars for moderate to severe crowding over 10mm, and avoiding incisor extractions when possible. It also discusses how extraction of different teeth will impact anchorage and the movement of surrounding teeth. Serial extractions, while once used, are no longer recommended due to requiring multiple procedures under anesthesia and potential mesial drift.
IMPACTED CANINE
The management of impacted canines is important in terms of esthetics and function. Clinicians must formulate treatment plans that are in the best interest of the patient and they must be knowledgeable about the variety of treatment options. When patients are evaluated and treated properly, clinicians can reduce the frequency of ectopic eruption and subsequent impaction of the maxillary canine. The simplest interceptive procedure that can be used to prevent impaction of permanent canines is the timely extraction of the primary canines. This procedure usually allows the permanent canines to become upright and erupt properly into the dental arch, provided sufficient space is available to accommodate them. In the present article, an overview of the incidence and sequelae, as well as the surgical, periodontal, and orthodontic considerations in the management of impacted canines is presented.

types of malocclusion.docx
Types of malocclusion
Malocclusion can occur singly or in combination as follows:
1- Dental mal-relationship.
2- Dento-alveolar, involving the teeth and alveolar process.
3- Dental arch mal- relationship
4- Basal arch discrepancy
5- Cranio-facial abnormalities.
1- Dental mal relationship
Including crowding, spacing, ectopism and other local malposition of the teeth that not affect the arch size, relationship and growth.
Causes of dental malposition:
1- genetic factors.
2- Prolonged retention or early loss of primary teeth.
3- Delayed eruption of permanent teeth.
4- Supernumerary teeth, missing teeth, either congenital or due to extractions.
5- Ectopic eruption and abnormal tooth morphology.
6- Abnormal development of the teeth.
Frequency:
=The most frequently malposed teeth in permanent dentition are the 3rd molars, maxillary lateral incisors, mandibular incisors, 2nd premolars and 2nd molars, the less frequently malposed teeth are the 1st molars and 1st premolars.
= spacing is predominating in deciduous dentition while crowding is common in permanent dentition.
= Irregularities due to local pot natal causes will manifest themselves clinically and will requires corrective treatment.
= rotation of the teeth in most cases is a sequlea of crowding but sometimes occurs with spacing due to loss of proximal contact between the erupting and adjacent teeth.
= crowding and spacing of the same arch may be expected in deciduous dentition but if occurs in permanent dentition, it will represent a symptoms of tooth shifting and detective eruption due to local interfere.
Spacing of permanent teeth:
In the permanent dentition, spacing in the maxillary arch is usually localized from canine to canine.
The median diastema in maxillary arch may be caused by:
1- Abnormal labial Frenum or presence of mesiodense
2- Dwarfed or congenitally absent lateral incisors.
3- Or as a part of generalized spacing.
Spacing in the mandibular arch is less common but may occurs due to:
1- Abnormal large tongue and bi dental protrusion.
2- Abnormal lingual Frenum ----- median diastema.
3- As a part of generalized spacing.
Loss of space or space closure:
a- In mixed dentition:
= In children with well-developed arches, there is little or no space loss after extraction of primary molars, this may be due to the cuspal interlocking of U and L 6
= There will be more space loss after extraction of E then after extraction of D
= loss of UE before the eruption of UB causes the U6 to erupt far mesially toward UD occupying the space required for eruption of U5------ impaction of U5.
= in the mandibular arch the forward shifting of L6 is less great and space loss is less marked.
= the order of eruption of permanent teeth has some effect on determining the space closure. For example: the maxillary canine may block out labially because it erupts after U4, the mandibular 2nd bicuspids may block out lingually because it is the last tooth erupt in the front of L6.

Clinicians must formulate treatment plans that are in the best interest of the patient and they must be knowledgeable about the variety of treatment options. When patients are evaluated and treated properly, clinicians can reduce the frequency of ectopic eruption and subsequent impaction of the maxillary canine. The simplest interceptive procedure that can be used to prevent impaction of permanent canines is the timely extraction of the primary canines. This procedure usually allows the permanent canines to become upright and erupt properly into the dental arch, provided sufficient space is available to accommodate them. In the present article, an overview of the incidence and sequelae, as well as the surgical, periodontal, and orthodontic considerations in the management of impacted canines is presented.

Affection and treatment of teeth
This document discusses various congenital abnormalities, irregularities, diseases, and tumors that can affect teeth in animals. It describes conditions like abnormal tooth number or position, persistent baby teeth, and sharp molars. Treatment recommendations are provided for each condition, such as tooth extraction, rasping, or surgical removal of tumors.
Impaction
This ia educative PPT for students and patients to help them understand the surgical removal of impacted third molar teeth.
This will ease in understanding the complexity of surgical procedure.
Extractions in orthodontics
it explain need for extraction, choice of teeth for extraction, Wilkinson extraction, extraction of permanent teeth without appliance therapy, balance extractions, compensating extractions, additional factor to consider in extraction of teeth.
types of malocclusion.docx
Types of malocclusion
Malocclusion can occur singly or in combination as follows:
1- Dental mal-relationship.
2- Dento-alveolar, involving the teeth and alveolar process.
3- Dental arch mal- relationship
4- Basal arch discrepancy
5- Cranio-facial abnormalities.
1- Dental mal relationship
Including crowding, spacing, ectopism and other local malposition of the teeth that not affect the arch size, relationship and growth.
Causes of dental malposition:
1- genetic factors.
2- Prolonged retention or early loss of primary teeth.
3- Delayed eruption of permanent teeth.
4- Supernumerary teeth, missing teeth, either congenital or due to extractions.
5- Ectopic eruption and abnormal tooth morphology.
6- Abnormal development of the teeth.
Frequency:
=The most frequently malposed teeth in permanent dentition are the 3rd molars, maxillary lateral incisors, mandibular incisors, 2nd premolars and 2nd molars, the less frequently malposed teeth are the 1st molars and 1st premolars.
= spacing is predominating in deciduous dentition while crowding is common in permanent dentition.
= Irregularities due to local pot natal causes will manifest themselves clinically and will requires corrective treatment.
= rotation of the teeth in most cases is a sequlea of crowding but sometimes occurs with spacing due to loss of proximal contact between the erupting and adjacent teeth.
= crowding and spacing of the same arch may be expected in deciduous dentition but if occurs in permanent dentition, it will represent a symptoms of tooth shifting and detective eruption due to local interfere.
Spacing of permanent teeth:
In the permanent dentition, spacing in the maxillary arch is usually localized from canine to canine.
The median diastema in maxillary arch may be caused by:
1- Abnormal labial Frenum or presence of mesiodense
2- Dwarfed or congenitally absent lateral incisors.
3- Or as a part of generalized spacing.
Spacing in the mandibular arch is less common but may occurs due to:
1- Abnormal large tongue and bi dental protrusion.
2- Abnormal lingual Frenum ----- median diastema.
3- As a part of generalized spacing.
Loss of space or space closure:
a- In mixed dentition:
= In children with well-developed arches, there is little or no space loss after extraction of primary molars, this may be due to the cuspal interlocking of U and L 6
= There will be more space loss after extraction of E then after extraction of D
= loss of UE before the eruption of UB causes the U6 to erupt far mesially toward UD occupying the space required for eruption of U5------ impaction of U5.
= in the mandibular arch the forward shifting of L6 is less great and space loss is less marked.
= the order of eruption of permanent teeth has some effect on determining the space closure. For example: the maxillary canine may block out labially because it erupts after U4, the mandibular 2nd bicuspids may block out lingually because it is the last tooth erupt in the front of L6.

How to Make a Field Mandatory in Odoo 17
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.
Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
