[Prosthodontic treatment in delayed pressure urticaria]

Area of Science:

• Dentistry
• Allergy and Immunology

Background:

• Systemic etiologic factors can complicate minimally invasive therapies.
• Dermal pressure urticaria and polyvalent anaphylactic reactions present unique challenges in dental treatment planning.

Observation:

• A patient presented with oral urticaria and a history of anaphylactic reactions.
• The primary goal was to determine how to load the edentulous alveolar ridge and distribute selective support on abutment teeth.

Findings:

• Removable partial dentures were designed using selective support principles for both upper and lower arches.
• A full denture was fabricated for the maxilla, and a partial metal plate for the mandible.
• Functional impressions maximized mixed dental and mucogingival support, resulting in good mucosal tolerance with only minor, adjustable edema.

Implications:

• Occlusal load on the edentulous mucosa can be managed in patients with pressure urticaria.
• Proper denture design is crucial to prevent severe complications like giant or Quincke's edema, which can be life-threatening.
