Risk of Late Implant Loss and Peri-Implantitis Based on Dental Implant Surfaces and Abutment Types: A Nationwide Cohort Study in the Elderly.
Article in Journal of clinical periodontology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
aimThis nationwide population-based cohort study aimed to assess the incidence of implant complication treatments, including implant removal procedures and peri-implantitis treatments, in relation to implant surfaces and abutment types.
methodsData from the National Health Insurance Service, covering approximately 50 million individuals, were used. Implants and abutments were categorized by codes, including surfaces such as resorbable blasting media, sandblasted large grit and acid-etched (SA) and hydroxyapatite coating, along with abutment structures (one-piece straight, two-piece straight, angled). The incidence of implant complication treatments was analysed using Kaplan-Meier curves and Cox proportional hazards regression (α = 0.05).
resultsThe study included 2,354,706 implants. The SA group had the lowest hazard ratio for implant removal procedures (p < 0.0001). No significant differences were found in the risk of peri-implantitis treatments between implant surfaces (p = 0.0587). The risk of implant complication treatments did not differ significantly by the abutment type (p = 0.9542). The incidence rate of implant complication treatments was < 3.9 per 1000 implant-years across all groups.
conclusionsThe SA group showed a slightly lower risk of late implant loss, whereas no significant association was found for the abutment type groups. All implant and abutment type groups showed an incidence rate of < 3.9 per 1000 implant-years for complication treatments.
