Mandibular overdenture retained with precision balls and bar attachment

Introduction. Milled precision bar with the lateral additions of two attachments could significantly contribute to primary and secondary retention partial denture overdenture. This clinical case demonstrates stability mandibular overdenture using milled coronally positioned attachments. Case report. A sixty-five years old male patient had preserved canine roots in lower jaw. Semicircular metal-ceramic (PFM) bridge was previously fabricated for upper teeth. Decision fabrication metal framework established due presence PFM The root canals remaining canines were prepared posts. After final impression A-silicone a custom tray, master cast provided. Two posts connected designed. Coronal attachments-patrixs onto tip each coronal part construction axial direction towards canals. invested casted. Metal designed interocclusal record, artificial anatomic teeth selected waxed model matrixes provided try-in phase. Finally, flasked polished. cemented simultaneously overdenture, self-adhesive resin cement. Conclusion. improves Coronally patrix attachment provides redirection occlusal other functional forces apical parts.
