Survival rate and need for maintenance of cover-denture prostheses borne on three or less abutment teeth: ten-year results.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
statement of problemWhen providing patients with cover-denture prostheses, even teeth with poor long-term prognosis can serve as abutment teeth. This has a positive psychological effect on patients and makes it easier to adapt them later to a complete denture. PURPOSE: Aim of the present study was to investigate the survival rate and need for maintenance of cover-denture prostheses.
methodsData were collected from patient records. Statistical analysis was performed using Kaplan-Meier survival analyses, log-rank tests (P < 0.05), Cox regressions (P < 0.05), and Non-Parametric Mean Cumulative Function.
resultsTwo hundred twenty-seven cover-dentures in 204 patients were examined. Mean age was 67 years, mean follow-up time was 3.4 years. 27.75% of prostheses were borne on one abutment tooth, 40.97% on two and 31.28% on three abutment teeth. In 60.4% percent of cases, copings were cast from a precious alloy. The 5-year survival rate for cover-dentures was 64.5%. The most common complication (36.6%) was decementation of a coping. In 30.9% of cases, one or more abutment teeth fractured and in 28.7% of cases one or more abutment teeth were lost. Most common need for maintenance was the removal of pressure points in the prosthesis. In 29.5% of cases, a relining of the cover-dentures was necessary.
conclusionA cover-denture prosthesis is a suitable therapeutical option for patients with few remaining teeth. The survival rate is comparable to that of other double crown retained removable partial dentures and occurring complications are manageable. Cover-denture prostheses represent an adequate alternative to complete extraction and can be recommended in clinical practice.
