An innovative approach for retreatment of prosthetically failing implant-supported fixed prostheses with a complete digital workflow: A technique report.

Abstract

Complications in fixed implant prostheses are frequently encountered and can negatively impact patients' quality of life. This technique outlines a complete digital workflow for the remake of full-mouth, implant-supported, cement-retained restorations necessitated by esthetic and functional impairments. For the digital recording of reused abutments, a contemporary technique was employed in which extraorally scanned abutment data were digitally superimposed onto their corresponding counterparts in the intraoral scans. The jaw relation record procedures were completed in stages. Initially, centric relation was recorded using a graphic recording technique with a gothic arch tracer. This was followed by capturing mandibular movements under anterior guidance as real movement data using the Jaw Motion Analyzer (Zebris). Based on these digital records, the definitive prostheses were designed and delivered. Follow-up was conducted at six months to evaluate clinical outcomes.
