Complications Associated with Metal Resin Fixed Complete Dentures Based on Implant Distribution

Area of Science:

• Dental Implantology
• Prosthodontics
• Biomaterials

Background:

• Metal resin fixed complete dentures are a common restorative option.
• Understanding complications associated with these prostheses is crucial for patient outcomes.
• Implant distribution is a key factor in prosthesis stability and longevity.

Purpose of the Study:

• To compare the prevalence and types of complications in metal resin fixed complete dentures.
• To evaluate the influence of implant distribution on complication rates.
• To identify factors associated with tooth delamination in implant-supported dentures.

Main Methods:

• Retrospective study of 223 patients over 12 years at Loma Linda University School of Dentistry.
• Data collection included implant distribution, complication prevalence, and covariates (age, sex, opposing arch, cantilever, implant number).
• Statistical analysis using descriptive statistics and logistic regression, with significance at alpha=0.05.

Main Results:

• Tooth delamination was the most prevalent complication, regardless of implant distribution.
• No statistically significant effect of implant distribution on tooth delamination was found in the maxillary arch.
• Denture tooth delamination was significantly higher in patients with opposing fixed complete dentures compared to removable ones.

Conclusions:

• Implant distribution is not a significant factor influencing complications in metal resin fixed complete dentures.
• The presence of opposing fixed complete dentures is significantly associated with an increased risk of denture tooth delamination.
• Further research may explore specific prosthetic designs and occlusal schemes to mitigate delamination.
