Implant Survival and Radiographic Outcome of a Novel Implant With a Machined Long Neck: A 1-Year Retrospective Study.
Article in Clinical implant dentistry and related research, 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
introductionThe primary objective was to assess 1-year clinical and radiographic outcomes of a newly designed implant with a machined long neck in the anterior region, including marginal bone loss, horizontal bone width, vertical bone height, and implant survival and success rates. The secondary objective was to evaluate the effect of guided bone regeneration on bone dimensional changes and implant survival and success rates. MATERIALS AND
methodsA total of 117 implants in 58 patients who received the novel implant in the anterior region were included. Marginal bone loss, horizontal bone width, and vertical bone height changes were assessed using panoramic radiographs and cone beam computed tomography (CBCT) scans obtained after prosthetic restoration and at the one-year follow-up. Implant survival and success rates, along with the influence of guided bone regeneration (GBR) on bone dimensional changes, were statistically analyzed.
resultsWithin the one-year follow-up period, implant survival and success rates were 97.43% and 91.45% at the implant level, and 94.83% and 82.76% at the patient level, respectively. Among the 114 surviving implants, the mean marginal bone loss was 0.46 ± 1.05 mm. In the subset of 32 implants with available CBCT data, horizontal bone width and vertical bone height changes were minimal in both buccal and palatal/lingual aspects. Subgroup analyses indicated that guided bone regeneration provided measurable advantages in preserving bone dimensions at specific sites, particularly in the mid-buccal region and the palatal/lingual vertical height. However, at most other reference points, dimensional changes were comparable irrespective of whether GBR was performed.
conclusionA novel implant featuring a machined long neck exhibited clinically acceptable outcomes with respect to implant survival, implant success, and bone dimensional stability over a one-year follow-up period.
