Study Notes

Temporomandibular Joint Disorders: Management

Temporomandibular Disorders (TMD) are conditions involving abnormal, incomplete, or impaired function of the temporomandibular joints.
Management initially involves conservative, non-surgical approaches.
Treatment strategies should be tailored to individual patients and consider the presenting complaint's history.

Outline

Includes quick revision, non-surgical management, self-management, physical therapy, pharmacological therapy, and occlusal appliances.

Self-Management

Aims to provide reversible protocols for managing TMD.
Key components include patient education, awareness of parafunctional behaviors (unilateral chewing, pen chewing, nail biting, gum chewing), thermal therapy, massage, and relaxation techniques.
Importance of explaining to patients that some symptoms (e.g., clicking) may persist despite self-management strategies.
Dental practitioners should reassure patients, clearly explain the diagnosis, provide tailored advice, and identify potential psychological factors.
Patient education should use simple language, covering the condition's nature, predisposing/precipitating/prolonging factors, TMJ anatomy, and management strategies/treatment goals.
Evidence suggests that educating patients about their condition can reduce pain.
Individuals with temporomandibular hypermobility (subluxation) should avoid extreme mouth openings (e.g., during yawning) and consider placing their tongue on their palate during yawning.
Awareness of parafunctional behaviors should be emphasized. Monitoring and avoiding habits like unilateral chewing, chewing pens, and gum can help minimize stress on the masticatory system.

Thermal Therapy

Localized thermal therapy is effective in relieving pain and relaxing muscles in myalgia patients by encouraging vasodilation and increasing blood flow.
Applying hot compresses to the painful muscle for 5 minutes three times a day provides symptomatic relief (considered low evidence).

Massage

Self-massage should be targeted to areas of discomfort or tense masticatory muscles, involving kneading, friction, and stretching techniques.
Self-massage can improve blood circulation and reduce tension in masticatory muscles.

Relaxation Techniques

Positive emotional states, self-confidence, relaxation, and beliefs that pain is manageable can improve a patient's pain experience.

Physiotherapy

Aims to restore movement and function in those with injury, illness, or disability.
Focuses on exercises/stretches, massage, and heat therapies to address injuries, manage conditions, and recover from surgeries.
Provided by physiotherapists, a reversible, cost-effective option.
Includes education on movement/exercise & physical activity, manual therapy to relieve pain/stiffness, and encourage better body movement.
Therapeutic goals focus on decreasing pain, aiding muscle relaxation, reducing muscular hyperactivity, improving function, and improving quality of life.

Physiotherapy Techniques

Includes manual therapy, jaw exercises, stretching, and postural training.

Psychological Intervention

If a patient presents with underlying mental health issues, ensure they receive proper support or refer them to a general medical practitioner.
Cognitive Behavioral Therapy (CBT) is a structured, evidence-based psychotherapy that identifies, modifies, and challenges negative thinking patterns and behaviors.
CBT can help reduce stress and anxiety - common TMD triggers.
CBT does not outperform non-surgical interventions but does support TMD management.

Physical Therapy Treatment

Includes therapeutic exercises, manual therapy, electrotherapy (including Transcutaneous Electrical Nerve Stimulation [TENS]), low-level laser therapy, and acupuncture.
Aims at providing short-term symptom relief and restoring function by reducing inflammation, pain, and muscular activity and promoting repair and regeneration.

Pharmacological Therapy

Comprehensive medical history is required to prevent drug interactions and adverse reactions, particularly in individuals with complex medical backgrounds.
A range of medications (analgesics, anti-inflammatories, muscle relaxants/anxiolytics, neuromodulatory agents, and miscellaneous agents) can be used to manage both acute and chronic TMDs.

Occlusal Appliances

Removable dental appliances made of acrylic or thermoplastic material for managing dental/musculoskeletal conditions.
Modifies occlusal surfaces and mandibular position.
Types include: soft splints/night guards, hard stabilization splints/stabilization splints, anterior positioning splints, and anterior bite splints.
Objectives include reducing TMJ loading, establishing vertical dimension, and distributing occlusal forces.

Splint Types

Soft/Resilient Splints: Made from soft materials, more comfortable but less durable. Used for diagnostic purposes and sports protection, does not account for bite.
Stabilization Splints: Full coverage, hard, acrylic splints. Constructed with least teeth for maximum occlusal contact to protect teeth from wear. Designed to contact evenly throughout the teeth in centric relation, distribute occlusal forces, eliminate occlusal interferences, and protect restorations from fracture related to bruxism.
Anterior Repositioning Splints: Designed to reposition anteriorly displaced disks. Only used for disk displacement with reduction in patients. Bite recorded at the point where the disk recontacted the condyle.
Anterior Bite Splint: Partial coverage splint, discludes posterior teeth, can lead to long-term problems if worn for extended periods due to uncovering teeth. Indicated in acute TMD situations with limited mouth opening.
Evidence on splint usefulness in TMD management is mixed.
