Clinical evaluation of failures in removable partial dentures

Area of Science:

• Dentistry
• Prosthodontics
• Oral Health

Background:

• Removable partial dentures (RPDs) are common prosthetic solutions for missing teeth.
• Long-term effects of RPDs on supporting oral tissues require thorough evaluation.
• Understanding changes in tooth mobility and abutment integrity is crucial for RPD success.

Purpose of the Study:

• To assess the 5-year clinical outcomes of removable partial dentures.
• To evaluate the impact of RPDs on support tissues, including tooth mobility and abutment health.
• To compare outcomes between different RPD designs (tooth-supported vs. distal-extension).

Main Methods:

• A 5-year clinical study involving 53 patients receiving RPDs.
• Patients were categorized into two groups based on their edentulous areas and remaining natural teeth.
• Evaluated parameters included tooth mobility, caries prevalence, abutment tooth integrity, RPD component stability, and denture base stability.

Main Results:

• RPD use was associated with increased tooth mobility and a reduced prevalence of caries.
• No significant loss or fracture of abutment teeth was observed.
• No damage to RPD components or denture bases occurred over the 5-year period.
• No significant differences in outcomes were found between the two patient groups.

Conclusions:

• Removable partial dentures can be used safely for 5 years without compromising abutment teeth or denture components.
• While RPDs may increase tooth mobility, they contribute to reduced caries prevalence.
• The evaluated RPD designs demonstrated comparable long-term stability and safety for supporting tissues.
