Article in Cureus, 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
Dental implants are a predictable treatment option for the replacement of missing teeth; however, complications related to implant positioning and proximity to adjacent anatomical structures may result in discomfort and compromise long-term outcomes. Cone beam computed tomography (CBCT) plays an important role in the diagnosis and management of implant-related complications by providing detailed three-dimensional evaluation of implant position and surrounding anatomy. This case report describes the management of a symptomatic maxillary implant in a patient who presented with intermittent pain during mastication and occasional discomfort in the region of a previously restored implant-supported crown. The patient subsequently reported accidental ingestion of the implant crown and was referred to a hospital to rule out aspiration or airway involvement. Following medical evaluation, CBCT imaging was obtained and revealed a wide-diameter implant positioned in close proximity to the Schneiderian membrane. Based on the clinical and radiographic findings, treatment consisted of CBCT-guided explantation of the existing implant followed by site redevelopment using bone grafting and a collagen membrane. Three-dimensional digital planning was performed to optimize the position, angulation, and dimensions of the replacement implant while maintaining a safe relationship with the Schneiderian membrane. A narrower implant was subsequently placed according to the digital treatment plan. Postoperative healing was uneventful. After six months of osseointegration, a second-stage procedure was performed, and a healing abutment was placed for soft tissue maturation. A digital impression was obtained using a scan body, and a definitive implant-supported crown was fabricated and delivered. At follow-up, the patient reported complete resolution of symptoms, satisfactory function, and improved comfort during mastication. Clinical and radiographic evaluation demonstrated successful implant integration and stable peri-implant tissues. This case highlights the value of CBCT-guided diagnosis, explantation, and reimplantation in the management of symptomatic implants located near the Schneiderian membrane and demonstrates the importance of three-dimensional planning in achieving predictable functional and restorative outcomes.
