Duplicate casts in fabrication of temporary removable partial dentures.

Area of Science:

• Dental prosthetics
• Removable prosthodontics

Background:

• Fabrication of temporary removable partial dentures often involves adjustments at insertion.
• Improper fit can lead to intraoral damage and patient discomfort.

Purpose of the Study:

• To describe a technique using blocked-out duplicate casts for fabricating temporary removable partial dentures.
• To ensure proper fit and minimize intraoral damage during prosthesis fabrication.

Main Methods:

• Utilizing blocked-out duplicate casts during the laboratory fabrication phase.
• Performing relief adjustments via block out on the surveyor.
• Salvaging the original cast for reference during finishing.

Main Results:

• Temporary removable partial dentures fabricated with this method exhibit accurate fit.
• The technique effectively minimizes the need for intraoral grinding at insertion.
• The original cast remains intact and usable for laboratory reference.

Conclusions:

• Blocked-out duplicate casts provide a controlled method for fabricating well-fitting temporary removable partial dentures.
• This technique enhances prosthetic accuracy and reduces potential for intraoral trauma.
• Preservation of the original cast facilitates laboratory procedures.
