Common Post-fitting Complications in Tooth-supported Fixed-Fixed Design Metal-Ceramic Fixed Dental Prostheses

Area of Science:

• Dental Prosthodontics
• Biomaterials Science
• Clinical Dentistry

Background:

• Metal-ceramic fixed dental prostheses (MC-FDPs) are widely used restorative solutions.
• Understanding complication frequencies and severity is crucial for improving long-term outcomes.
• Previous research highlights various failure modes, necessitating focused investigation on MC-FDPs.

Purpose of the Study:

• To determine the frequency and severity levels of common complications associated with MC-FDPs.
• To identify the most prevalent complications and their distribution.
• To analyze the timing of complication occurrence relative to prosthesis service life.

Main Methods:

• A descriptive cross-sectional study was conducted involving 139 subjects with MC-FDPs.
• Data collection utilized interviews, clinical examinations, and radiographic assessments.
• A structured proforma was employed to record complication details.

Main Results:

• De-cementation was the most frequent complication (41.7%), followed by secondary caries (6.5%).
• Level-1 complications (77.7%) were significantly more prevalent than level-2 complications (22.3%).
• Over 91% of complications occurred within five years of service, with 25.2% happening in the first year.

Conclusions:

• Level-1 complications, particularly de-cementation, are the most common issues in MC-FDPs.
• A substantial proportion of complications arise within the first year, indicating potential quality concerns.
• Findings underscore the need for improved quality control and patient monitoring for MC-FDPs.
