Effect of Simultaneous Guided Bone Regeneration on Postoperative Pain Three Days After Dental Implant Surgery: A Prospective Cohort Study.
Article in Journal of oral rehabilitation, 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
objectiveGuided bone regeneration (GBR) is the most frequently used method for bone augmentation during dental implant surgery. This study was meant to explore the effect of simultaneous GBR on postoperative pain after dental implant surgery. MATERIAL AND
methodsThis prospective cohort study included 72 patients who were divided into the following two groups based on whether GBR was performed: Group A (single dental implant placement) and Group B (single dental implant placement with GBR simultaneously). Before the surgery, patients' anxiety status and pain sensitivity were assessed via the State-trait anxiety inventory (STAI) and pain sensitivity questionnaire (PSQ), respectively. The pain values at 2 h, 4 h, 6 h, 24 h, 48 h and 72 h post-operation were recorded using a numerical rating scale. The independent samples t-test was performed to evaluate the difference, and p-values < 0.05 were considered statistically significant.
resultsA total of 60 patients completed follow-up, with 30 patients remaining in each group. Patients in Group B experienced moderate pain after the implant surgery, with the peak of pain occurring at 4 h post-operation. And the average pain score in Group B was 4.77, which was higher than that in Group A (2.93). Furthermore, the difference in pain scores between the two groups at 4, 6 and 24 h after surgery was statistically significant (p = 0.002, 0.001 and 0.003, 95% CI = [-2.98, -0.69], [-2.40, -0.67] and [-1.05, -0.22], respectively).
conclusionPatients undergoing simultaneous GBR during dental implant surgery tend to experience more postoperative pain, reaching up to or exceeding a moderate level. Therefore, we suggest to pay more attention on pain management after dental implant surgery with GBR to improve postoperative comfort.
