Effect of immediate provisionalization using natural crowns with fiber splints on gingival contour and esthetic outcomes after immediate implant placement: a randomized clinical trial.
Trial report in BMC oral health, 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
backgroundImmediate implant placement (IIP) requires sufficient primary stability to permit implant-supported immediate provisionalization, which supports peri-implant soft tissue contour during healing, particularly in the anterior esthetic zone. This exploratory study aimed to evaluate the effect of using natural crowns combined with fiber-reinforced composite (FRC) splints on gingival contour and esthetic outcomes following IIP in the esthetic zone dental trauma over a 4–5-month follow-up period.
methodsA total of 20 participants who underwent IIP in the anterior maxilla were enrolled in this study. Participants were randomly allocated to an experimental group receiving immediate restoration using natural crowns combined with FRC splints and a control group receiving delayed restoration. Postoperative pain and swelling were assessed using the visual analogue scale (VAS). At 4–5 months postoperatively, gingival esthetics were evaluated using the pink esthetic score (PES), and changes in gingival height (mesial papilla, distal papilla, and mid-labial gingival margin) were measured using intraoral optical scans. Implant success rates were also recorded.
resultsThe implant placement success rates were 100% in both groups. Postoperative pain and swelling scores were significantly lower in the experimental group than in the control group (p < 0.05). The experimental group demonstrated significantly higher PES values compared to the control group (z = 2.799, p = 0.005). No significant intergroup differences were observed in gingival height changes at the mesial papilla, distal papilla, or mid-labial gingival margin.
conclusionsImmediate provisionalization using natural crowns with FRC splints may reduce postoperative discomfort and improve overall esthetic outcomes while maintaining comparable gingival height stability during early healing.
trial registrationThis randomized controlled trial was prospectively registered in the Chinese Clinical Trial Registry (ChiCTR) prior to the enrollment of participants (ChiCTR2300068934; registered on March 1, 2023).
