    Flashcards

    Crowding and Periodontal Problems

    Crowding where one or more teeth are pushed outwards, leading to reduced periodontal support and gum recession.

    Traumatic Overbite

    A deep bite where upper teeth bite onto the gums, causing inflammation and potential bone loss over time.

    Overjet and Trauma

    Having a large overjet (protruding upper front teeth) increases the risk of upper incisor trauma.

    Tooth Impaction

    A tooth that's stuck in the jaw bone and unable to erupt normally.

    Ectopic Tooth

    A tooth that has formed in the wrong position or moved there later, often leading to impaction.

    What is Orthodontics?

    Orthodontics is the dental specialty focused on the growth and development of teeth and jaws, as well as diagnosing and treating bite problems.

    What is the difference between ideal occlusion and malocclusion?

    Ideal occlusion is the perfect arrangement of teeth, both within the upper and lower jaws and how they come together when biting. Malocclusion is any deviation from this ideal bite.

    What are the potential benefits of orthodontic treatment?

    Orthodontic treatment can improve both oral health and overall well-being. It helps prevent issues like tooth decay, gum disease, and even jaw problems.

    What is root resorption?

    Root resorption is when the root of a tooth is damaged, potentially shortening the tooth. It's a possible side effect of orthodontic treatment.

    Study Notes

    Orthodontics

    • Orthodontics diagnoses, intercepts, and treats occlusal irregularities
    • Focuses on facial growth, dental development, and occlusion

    Malocclusion

    • Ideal occlusion is a perfect anatomical positioning of teeth
    • Malocclusion represents deviations from ideal occlusion
    • Prevalence varies by population (age, race), assessment criteria, and methods
    • UK data suggests around 40-50% of adolescents have moderate-to-severe malocclusion

    Rationale for Orthodontic Treatment

    • Malocclusion can impact dental health and oral-health-related quality of life (OHRQOL)
    • Treatment need depends on malocclusion's impact and potential benefit
    • Risk-benefit analysis is crucial (weighed benefits against potential complications)

    Need for Orthodontic Treatment

    • Health and well-being benefits are the primary determinant
    • Orthodontic indices (e.g., IOTN) assess potential risks and benefits
    • Treatment need is sometimes rationed due to high demand

    Demand for Orthodontic Treatment

    • Demand may not always reflect the need for treatment.
    • Some patients are aware of minor deviations while others refuse treatment for more significant irregularities.

    Potential Benefits to Dental Health

    • Certain malocclusions can increase risk of periodontal problems, trauma, and caries.
    • Orthodontic treatment can address these problems and potentially improve long-term dental health in some cases
    • Not beneficial for all conditions (e.g., caries, periodontal diseases, TMD)

    Localized Periodontal Problems

    • Malocclusion-related concerns impacting the gums
    • Examples include crowding, trauma overbites, and anterior crossbites

    Dental Trauma

    • Increased overjet more than doubles the risk of incisor injuries
    • Risk increases with overjet size and lip incompetence
    • Orthodontics may be necessary in at-risk individuals

    Tooth Impaction

    • Impaction occurs when tooth eruption is blocked by other teeth, bone, soft tissue, or other issues.
    • Supernumerary teeth can cause impaction
    • Orthodontic intervention is required if impaction impacts dental development

    Caries

    • Limited correlation between malocclusion and caries
    • Orthodontic treatment is not usually a solution for caries
    • Reduced access for cleaning is a risk factor for the development of caries in those with issues maintaining good oral hygiene practices

    Plaque Induced Periodontal Disease

    • Oral hygiene and plaque control are critical in preventing periodontal issues.
    • Malocclusion is a weaker factor in periodontal diseases

    Temporomandibular Joint Dysfunction Syndrome (TMD)

    • TMD is a complex disorder with many potential causes
    • Orthodontic treatment alone is not considered a reliable cure or cause of TMD
    • TMD screening is advised for potential orthodontic patients
    • Orthodontics can improve issues related to appearance, mastication, speech, and psychosocial well-being.

    Appearance

    • Dental dissatisfaction is often the primary reason for treatment
    • Perceived benefits of appearance changes might be linked to psychosocial improvements

    Masticatory Function

    • Malocclusion like severe open bites can create difficulty during eating by avoidance of some foods..
    • Orthodontic treatment can improve masticatory function, improving quality of life for patients that are facing difficulty with typical oral functions.

    Speech

    • Orthodontic treatment can have limited impact, as speech patterns usually develop before the permanent dentition.
    • May address lisping (e.g., interdental sigmatism) caused by incorrect incisor relationships

    Psychosocial Well-being

    • Malocclusion is linked to lower self-confidence & self-esteem
    • Oral health impact can relate to social interactions.

    Potential Risks of Orthodontic Treatment

    • Potential risks warrant open communication and risk-management strategies
    • Patient plays an essential role in treatment success and treatment compliance.

    Root Resorption

    • Root resorption is often a consequence of tooth movement
    • Certain conditions increase resorption risk

    Loss of Periodontal Support

    • Increased gingival inflammation is common following appliance placement.
    • Important to emphasize oral hygiene, as inflammation may often resolve following the removal of appliances.
    • Loss of alveolar bone might occur due movement outside of intended bone structure.

    Demineralization

    • Demineralization (early stage of caries) risk during treatment due to reduced access for cleaning
    • Plaque accumulation

    Enamel Damage

    • Enamel damage from orthodontic appliances (during adjustments or removal); potential wear on opposite teeth

    Intra-Oral Soft Tissue Damage

    • Ulceration from orthodontic devices; usually temporary
    • Managing allergic reactions is important

    Pulpal Injury

    • Excessive root movement, can lead to compromised blood supply to the pulp (potentially pulpal death)
    • Careful monitoring for any patients with previous trauma

    Extra-Oral Damage

    • Potential concerns over facial profile changes during treatment (e.g., retraction)
    • Risk assessment of facial and cosmetic impact should be calculated prior to any procedure

    Relapse

    • Relapse is the return of initial conditions of malocclusion after treatment
    • Retention is important to prevent relapse

    Failure to Achieve Treatment Objectives

    • Errors in diagnosis, treatment planning, and technique might cause unsuccessful results, with several potential factors at play
    • Clinical evaluation and patient factors can affect outcome

    Discussing Orthodontic Treatment Need

    • Importance of patient and family participation in treatment decisions
    • Clinicians balance risks and benefits within the patient's context
