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

objectivesTo retrospectively evaluate whether implant apex flush with maxillary sinus notch is associated with greater bone augmentation of the concave sinus floor after graft-less transcrestal sinus floor elevation (TSFE) and simultaneous implant placement. MATERIALS AND

methodsAll patients treated with TSFE between January 2017 and June 2020 were screened via radiographs. Patients with concave sinus floor at the planned implant site were selected and divided according to a cohort design as follows: implant apex flush with the maxillary sinus notch (test group) or not (control group). Panoramic images were taken before surgery, immediately, and 4 months after surgery. Two-dimensional augmentation parameters, including endo-sinus bone gain (ESBG), and the ratio of ESBG to implant protrusion length (%ESBG) were measured to evaluate the bone augmentation effect.

resultsSixty-nine patients with a total of 69 implants (39: control group, 29: test group, 1: failure) were included in this retrospective research. At the 4-month follow-up, the ESBG and %ESBG of the test group [ESBG: 1.57 (0.58-2.37), %ESBG: 49.68% (15.38%-75.91%)] were significantly higher than those of the control group [ESBG: 0.48 (0.13-1.47), %ESBG: 11.73% (3.05%-27.96%), p < 0.05].

conclusionsThe present study preliminarily suggests that implant apex flush with the maxillary sinus notch may be associated with better bone augmentation of concave sinus floor in graft-less TSFE. CLINICAL RELEVANCE: This study is the first to propose the definition of the maxillary sinus notch and preliminarily explore its role in graft-less TSFE, providing novel insights into how implant protrusion length (IPL) affects bone augmentation.
