Bone regeneration following damage by polysulphide impression material. A case report

Area of Science:

• Dentistry
• Oral Surgery
• Periodontology

Background:

• Dental impressions are crucial for prosthodontic procedures.
• Polysulphide rubber is a common impression material.

Observation:

• A dental student experienced swelling after a gold inlay impression.
• Radiographs showed a radiopaque foreign body in the interdental septum.
• Surgical exploration revealed destroyed bone replaced by impression material and inflammation.

Findings:

• The interdental septum was destroyed by the foreign body.
• Significant bone regeneration occurred within two years after lesion removal.

Implications:

• Foreign bodies from dental procedures can cause significant bone destruction.
• The jawbone demonstrates remarkable regenerative capacity after surgical intervention.
