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
Implant rehabilitation in the posterior maxilla with severe vertical bone atrophy remains clinically challenging, particularly when bone augmentation procedures are not feasible or are refused by the patient. The use of ultrashort implants combined with dynamic navigation has been proposed as a minimally invasive alternative in selected cases; however, long-term clinical evidence in the maxilla is still limited. This case report describes the 10-year clinical and radiographic outcomes of a single 4-mm ultrashort implant placed in the posterior maxilla using dynamic navigation technology. A 47-year-old nonsmoking female patient presented with a single edentulous maxillary first molar and severe vertical bone resorption (≤ 5 mm). The patient declined bone augmentation and fixed partial denture therapy. Implant placement was planned and performed under dynamic navigation guidance, followed by restoration with a single implant-supported crown. Clinical and radiographic follow-up was conducted regularly up to 10 years after prosthetic loading. Throughout the follow-up period, no biological or prosthetic complications were observed. Peri-implant soft tissues remained healthy, with no bleeding on probing or suppuration. Radiographic evaluation using standardized periapical radiographs revealed a mean marginal bone loss of 0.35 mm at 10 years. The implant-supported crown maintained stable function and structural integrity, and the patient reported high satisfaction with the treatment outcome. Within the limitations of a single case report, these findings suggest that the combination of dynamic navigation and ultrashort implants may represent a reliable and minimally invasive treatment option for single implant rehabilitation in severely atrophic posterior maxillary sites. Further prospective studies with larger sample sizes and long-term follow-up are required to confirm the predictability and reproducibility of this approach.
