Alveolar Corticotomy-Assisted Orthodontic Closure of a Long-Standing Mandibular First Molar Edentulous Space: A Case Report.

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
Premature loss of a permanent first molar can lead to functional impairment, food impaction, occlusal instability, and compromised masticatory efficiency. While implant-supported rehabilitation is frequently used to restore missing posterior teeth, orthodontic space closure may provide a conservative alternative in selected patients. This case report describes the management of a 22-year-old healthy female patient who presented with a three-year history of an untreated mandibular right first molar edentulous space following the extraction of tooth #30 at the age of 19. The patient reported recurrent food accumulation within the edentulous area, irritation of the surrounding soft tissues, and difficulty chewing comfortably on the affected side. A multidisciplinary treatment plan was developed to close the edentulous space through mesial movement of teeth #31 and #32. To facilitate orthodontic tooth movement, alveolar corticotomy was performed under local anesthesia. Multiple cortical perforations were created within the edentulous ridge, followed by placement of a collagen membrane and stabilization with 4-0 nylon sutures. Orthodontic treatment was continued after healing to progressively advance the posterior teeth into the edentulous area. Substantial space closure was achieved after approximately eight months of active orthodontic movement, followed by additional treatment for alignment and occlusal refinement. Clinical and radiographic evaluation demonstrated favorable healing, successful reduction of the edentulous space, improved posterior occlusal support, elimination of food impaction, and enhanced masticatory function. The patient reported high satisfaction with both the functional and esthetic outcomes. This case highlights the potential of alveolar corticotomy-assisted orthodontics as a conservative treatment approach for managing long-standing posterior edentulous spaces and demonstrates its ability to facilitate challenging tooth movement while avoiding implant rehabilitation in appropriately selected patients.
