A new procedure to reinforce fixed provisional restorations

Area of Science:

• Dental Materials Science
• Prosthodontics
• Biomaterials Engineering

Background:

• Unreinforced fixed partial denture provisional restorations frequently fail due to material fractures and loss of cement retention.
• These failures compromise treatment outcomes and necessitate costly replacements.
• Improving the mechanical integrity and retention of provisional restorations is critical in prosthodontic care.

Purpose of the Study:

• To evaluate a novel procedure for reinforcing provisional restorations.
• To assess the impact of a substructure made from orthodontic band material on restoration longevity.
• To determine if this reinforcement method increases cost or construction time.

Main Methods:

• A procedure was developed to incorporate a substructure of orthodontic band material into provisional restorations.
• The reinforced provisional restorations were subjected to clinical evaluation.
• Comparison of failure rates between reinforced and unreinforced restorations was performed.

Main Results:

• The reinforcement procedure dramatically increased the longevity of the provisional restorations.
• Failures due to fractures and loss of cement retention were significantly reduced.
• The procedure utilized commonly available materials.

Conclusions:

• Reinforcing provisional restorations with orthodontic band material is a highly effective method to improve durability.
• This technique offers a significant increase in restoration longevity without substantial increases in cost or fabrication time.
• The findings support the clinical adoption of this reinforcement strategy in prosthodontics.
