Evaluation of atraumatic axial tooth extraction using Benex system in immediate implant in maxillary anterior teeth. A prospective clinical trial

Abstract

Objective: The aim of this study was to assess the practicability and clinical results of an atraumatic extraction method for maxillary anterior teeth using the Benex extraction system with immediate implant placement.Materials and Methods: Twelve dental implants placed immediately in ten adult patients having maxillary anterior tooth or remaining root indicated for extraction. All patients were operated under local anesthesia, with atraumatic extraction using Benex extraction system followed by immediate implant placement. Clinical and radiographic evaluation was performed and implant stability assessment was performed using radiofrequency analysis.Results: Twelve extractions were conducted successfully and followed by immediate implants placement in ten patients. None of the placed implants showed any complications in the clinical follow up period. Final prosthetic placement was conducted after 6 months with a mean reported pink esthetic score of 10.50 ± 0.80, and implant stability analysis reported an increase in the achieved Implant stability quotient by 8.83 ± 5.25. Radiographic analysis of the crestal alveolar bone width reported a mean decreased in crestal bone width by 0.25 ± 0.15 mm. The labial plate thickness analysis reported an increase in the bone thickness at the apical and middle levels, while a statistically insignificant decrease was reported at the coronal level.Conclusion: Axial tooth extraction technique using Benex extraction system is a practicable modality with a favorable execution without socket expansion or jeopardizing remaining wall integrity. This minimally invasive extraction modality allowed for immediate implant placement with favorable clinical and radiographic outcomes.
