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

objectiveThis study aimed to assess the osseous positional and dimensional changes in the temporomandibular joint (TMJ) of patients with skeletal Class II malocclusion treated with the Forsus Fatigue Resistant Device (FFRD). MATERIALS AND

methodsThis non-randomized clinical trial included 40 female subjects, aged 11 to 15, with skeletal Class II malocclusion. Participants were divided into a treatment and a control group. After alignment and leveling with fixed orthodontic appliances using 0.019 × 0.025-inch stainless-steel archwires, the FFRD was fitted. The overjet was corrected to achieve an edge-to-edge incisor relationship. Cone Beam Computed Tomography (CBCT) images were taken before (T1) and after (T2) the fixed functional phase. The TMJs were assessed for positional and dimensional osseous changes in the mandibular condyles, glenoid fossae, and joint spaces. Intra- and inter-group comparisons were conducted using paired t-tests and independent t-tests, respectively.

resultsThe initial measurements of age, cervical stage, anteroposterior and vertical skeletal alignment, and TMJ parameters were similar between the study and control groups. Three participants from the study group were lost to follow-up, resulting in 17 participants completing the trial. In the treatment group, condylar width decreased significantly by 0.52 ± 0.92 mm, in contrast to an increase of 0.17 ± 0.35 mm in the control group (P = 0.010). Moreover, the anterior wall inclination in the treatment group was reduced by 3.13 ± 10.77 degrees, compared to an increase of 2.95 ± 4.1 degrees in the control group (P = 0.003). All other measurements displayed no significant differences between the two groups.

conclusionIn the short term, the FFRD redirected the growth of the articular eminence anteriorly, contrasting with the normal growth pattern of untreated individuals. However, no additional positional or dimensional changes in the TMJ were observed. CLINICAL RELEVANCE: By aligning the jaw and correcting overjet, clinicians can potentially enhance occlusal relationships and contribute to better jaw function. However, it is important to investigate whether this process is associated with any changes in the bony structures of the TMJ. This study underscores the efficacy of the FFRD in reshaping the osseous components of the TMJ, which may lead to improved functional outcomes for patients with skeletal Class II malocclusion.
