1 · What the graph read from it

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.

2 · The registry

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

purposeThis prospective clinical pilot study aimed to evaluate oral health-related quality of life (OHRQoL) and both objective and subjective masticatory function following treatment with implant-supported overdentures on two reduced-diameter titanium-zirconium implants in the edentulous maxilla and mandible.

methodsTen edentulous patients received two implants each in the maxillary and mandibular canine regions. Implant-supported overdentures were placed after a conventional healing period. Patients completed a shortened form of the Oral Health Impact Profile (OHIP-G14) and rated their chewing ability on a visual analog scale (VAS) at baseline and after 6, 12, 24, and 36 months. A standardized masticatory function test assessed objective chewing function. Statistical analysis comprised descriptive analysis and changes or differences in means were analyzed using different tests (Wilcoxon signed rank test, Friedman test).

resultsSignificant increases in subjective ability to eat various foods were noted after six months (P ≤.05). The mean total OHIP score decreased significantly from 33.2 at baseline to 4.7 at the 36-month follow-up. Objective masticatory efficacy showed significant improvement immediately after treatment (P =.005), with effects consistent over 36 months. At that time, six maxillary implants had been lost, while no mandibular implants had failed.

conclusionsIn this clinical pilot study, the rehabilitation of a completely edentulous maxilla and mandible with two implants and a removable overdenture significantly enhanced OHRQoL and both subjective and objective masticatory ability over an observation period of 36 months.
