Appliances for TMD Management Flashcards
1
Q
Occlusal appliance: General
A
- Hard acrylic device
- removable
- covers occlusal/incisal surface of teeth
2
Q
Occlusal Appliances are commonly known as?
A
- Occlusal splint
- bite guard
- night guard
- interocclusal appliance
- orthopedic devide (orthotic)
3
Q
What is the purpose of occlusal appliances?
A
- temporary stabilize or improve TMJ Function
- condyles= most ortho stable joint position
- Improve masticatory m. fxn
- reduce muscle activity
- Protect teeth and support structures from abnormal forces
4
Q
What are the different types of occlusal splints?
A
- Stabilization appliance
- Anterior Repositions appliance
- Anterior Bite Plane
- Posterior Bite Plane
- Soft or Resilient Appliance
5
Q
Stabilization appliance: General
A
- aka Bite Guard
- Covers entire arch (Full coverage)
- Occludes with all opposing teeth
- Occlusal surface
- flat
- indentation of opposing cusp tips
- Maxillary Appliance
- most common
- Mandibular Appliance
- Esthetic reasons
- Class 3 malocclusion
6
Q
Stabilization Appliance: Indications
A
- muscle pain disorders
- local muscle soreness
- central mediated myalgia
- Stress
- ⇣ parafunctional activity
- Retrodiscitis secondary to trauma
- minimize forces to damaged tissue→ better healing
7
Q
Stabilization Appliance: Main Purpose
A
- Provide occlusal and joint stability
- reduce parafunctional activity
8
Q
Anterior Repositioning Appliance: General
A
- Move mandible forward
- properly aligned discs
- eliminate pain and joint noise
- Goal:
- temporary alter position of mandible
- enhance retrodiscal tissue adaptation
- discontinue after adaptation
9
Q
Anterior Repositioning Appliance: Indications
A
- Disc displacement w/reduction
- intermittent or chronic joint locking
- Inflammatory disorders
- ex: Retrodiscitis
10
Q
Anterior Bite Plane: General
A
- Hard acrylic appliance
- Covers maxillary teeth
- occludes only mandibular anterior teeth
- disengages posterior teeth
- No influence on the masticatory system
11
Q
Anterior Bite Plane: Indications
A
- Treat Muscle Disorders
- Parafunctional activity
- Short periods only
12
Q
Anterior Bite Plane: Side Effects
A
- Supra-eruption of unopposed teeth
- Results in anterior open bite
13
Q
NTI
A
- AKA Nociceptic Trigeminal Inhibition Tension Suppression System (NTI TSS)
- Anterior Bite plane
- only anterior central incisors occlude
- Use to manage Headache
- Greater risk of permanent occlusion change vs stabilization appliance
14
Q
Posterior Bite Plane: General
A
- Hard acrylic appliance
- Made for mandibular teeth
- covers posterior teeth
- connected by cast metal lingual bar
- Dont use:
- Long term
- Constant
14
Q
Posterior Bite Plane: Indications
A
- Severe loss of Vertical dimension
- Improve Athletic performance by atheletes
- no evidence
- Disc derangement disorders
- not studied enough
