Study Notes

Causes of Alveolar Bone Loss

Extension of gingival inflammation is the most common cause.
Trauma from occlusion can contribute significantly.
Systemic factors and conditions such as periodontitis, periodontal abscess, food impaction, overhanging restorations, ill-fitting prostheses, and tooth extractions also play a role.

Physiologic Adaptive Capacity

The periodontium attempts to adjust to occlusal forces.
Individual variability exists in adaptive capacity.
Injury occurs when occlusal forces exceed reparative capabilities, termed trauma from occlusion.

Trauma from Occlusion

Defined as the tissue injury due to excessive occlusal forces.
Traumatic occlusion leads to tissue injury, not merely the occlusal force itself.

Factors Influencing Trauma

Magnitude: Increased occlusal forces lead to:
- Widening of periodontal ligament space.
- Increased number and width of periodontal ligament fibers.
- Greater density in alveolar bone.
Direction: Orientation of periodontal ligament fibers can change with altered occlusal forces.
Duration: Constant pressure is more harmful than intermittent forces.

Classification of Trauma

Acute Trauma: Abrupt changes in occlusion, often from hard biting or alterations in occlusal direction.
- Clinical features include tooth pain, sensitivity to percussion, and increased tooth mobility.
Chronic Trauma: More common, resulting from gradual changes like tooth wear, drifting, extrusion, bruxism, or clenching.

Primary and Secondary Trauma

Primary Trauma: Serves as the main etiological factor in periodontal destruction.
- Results in increased width of periodontal ligament space, thickening of lamina dura, vertical bone loss, and radiolucency in furcation areas.
Secondary Trauma: Occurs when the adaptive capacity of periodontal tissues is compromised.
- Alveolar bone loss frequently emerges as a primary concern and is challenging to treat.

Combined Trauma from Occlusion

Involves injury due to abnormal occlusal forces on teeth with inadequate periodontal support.
- Symptoms include progressive mobility, pain during chewing or percussion, fremitus, occlusal discrepancies, wear facets, tooth migration, and sensitivity.

Treatment Goals

Therapy aims to maintain periodontal health and comfort.
Possible treatments include:
- Occlusal adjustment and managing parafunctional habits.
- Stabilization of mobile teeth with fixed/removable devices.
- Orthodontic tooth movement and occlusal reconstruction.
- Extraction of select teeth as necessary.

Key Perspectives on Trauma

Trauma can leave lasting impacts beyond physical symptoms, as suggested by the quote from Dr. Ellen Taliaferro emphasizing the lingering effects of trauma.
Jodi Picoult reflects on the subjective experience of trauma and its aftermath.
