Explantation and Guided Repositioning of Two Mandibular Implants for Rehabilitation With an Implant-Mucosa-Supported Overdenture in a Patient With Advanced Peri-Implantitis: A Case Report.
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
Peri-implantitis is a biological complication that can compromise long-term implant survival and, in advanced cases, may indicate explantation. In patients with mandibular edentulism rehabilitated with implant-retained overdentures, the management of advanced peri-implant disease is particularly challenging when systemic factors and unfavorable peri-implant tissue conditions coexist. We report the case of a 73-year-old woman with a medical history of rheumatoid arthritis and Sjögren's syndrome who was wearing an implant-retained mandibular overdenture supported by two intraforaminal implants. She presented with prosthetic instability, peri-implant pain, and clinical and radiographic findings consistent with a Class IIIc combined peri-implant bone defect with advanced severity at the left mandibular site. Treatment included explantation of the affected implants followed by digitally planned, prosthetically guided immediate placement of two new intraforaminal implants. A subsequent soft tissue augmentation procedure with de-epithelialized free gingival grafts was performed to increase the band of peri-implant keratinized mucosa. Definitive rehabilitation was completed with an implant-mucosa-supported overdenture retained by low-profile Equator attachments (Rhein83, Bologna, Italy). At three months after loading, clinical and radiographic evaluation showed peri-implant stability, healthy soft tissues, and adequate prosthetic retention and function. The short follow-up does not allow conclusions regarding long-term outcomes, but the case illustrates a feasible workflow for managing advanced peri-implantitis in a medically compromised patient when conservative or regenerative strategies are considered unpredictable.
