Root-Retained Overdentures Enhance Stability and Patient Satisfaction confirms Systematic Review
Greece: A recent systematic review of randomized controlled trials has shed light on the clinical parameters affecting the performance and patient satisfaction of root-retained overdentures (RODs).
The research, published in Gerodontology, revealed that despite the limitations of this systematic review, root-retained overdentures continue to be a valid treatment option, providing enhanced denture stability, better bone preservation around abutment teeth, and high levels of patient satisfaction.
"Maintaining good oral hygiene and scheduling regular follow-ups are essential for success. Additionally, more well-designed randomized controlled trials are needed to draw more definitive conclusions," the researchers wrote.
Root-supported overdentures provide enhanced support, horizontal stability, improved retention, and better maintenance of proprioception and sensory feedback from the periodontal tissues, contributing to high patient satisfaction. As a successful treatment option for partially edentulous patients, RODs remain a viable alternative; however, conclusive evidence regarding their clinical evaluation is still lacking.
Against the above background, Aspasia Pachiou, Department of Prosthodontics, School of Dentistry, National and Kapodistrian University of Athens, Athens, Greece, and colleagues assessed the clinical parameters influencing the performance of root-supported overdentures and identified potential factors that may impact their effectiveness.
For this purpose, the researchers developed a search strategy based on the PIO (Population, Intervention, Outcome) framework, conducting an electronic search across several databases, including PubMed, Cochrane Library, and Scopus. This systematic search was limited to randomized controlled trials (RCTs) published in English until January 2023 and was carried out by two independent reviewers. The quality of the included studies was evaluated using the Cochrane Risk of Bias tool.
Findings from the Study:
- The final selection comprised 11 randomized controlled trials (RCTs).
- Clinically relevant variables identified included:
- Complications: Caries were the most frequently reported complication.
- Periodontal aspects and bone changes around abutment teeth.
- Assessment of methods and clinical recommendations for maintaining these restorations.
- Evaluation of patient-related outcomes.
- Risk of bias assessment revealed:
- Nine studies were classified as high risk.
- Two studies were classified as low risk.
- A meta-analysis was not feasible due to the study's characteristics.
In conclusion, using protective or preventive agents can significantly reduce the risk of root caries. For individuals with root-supported overdentures, maintaining meticulous oral hygiene and attending regular follow-up visits are essential. Additionally, addressing the maintenance needs of both RODs and abutment teeth is crucial for ensuring the long-term success of these dental devices.
