Immediate four implants supported short arch rehabilitation for severe maxillary edentulism.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To verify the feasibility of immediate short arch restorations with 4 implants in the maxillary anterior region. Patients who received immediate short arch restoration with 4 implants in the anterior region were enrolled in this retrospective study. Cone beam computed tomography (CBCT) was performed to evaluate the marginal bone loss. The incidence of prosthetic complications and patient complaints of discomfort were recorded and examined. Ten participants were enrolled in the study. Throughout the follow-up period of 13.7 ± 4.6 months, all implants used for immediate restorations in these patients demonstrated no failures. However, five patients experienced fractures of their short arch prostheses. The average marginal bone loss associated with the implants for immediate restorations was measured at 0.61 mm (95% confidence interval: 0.50 to 0.72 mm). Immediate short arch restoration with 4 implants is a potentially promising alternative in selected cases for maxillary edentulism with insufficient bone in the posterior region requiring lateral sinus floor elevation. This study presents an immediate short arch restoration using 4 implants in the maxillary anterior zone. The results indicate that immediate short arch restoration is a viable option for addressing maxillary edentulism, particularly in cases with inadequate posterior maxillary bone. However, further long-term studies are required to confirm its efficacy and stability over time.
