Management Of Different Types Of Through And Through Defectsusing Guide Tissue Regeneration (Gtr), Amro Elkhatieb
Management Of Different Types Of Through And Through Defectsusing Guide Tissue Regeneration (Gtr), Amro Elkhatieb
Excellence Day
Through and through defects result in perforation of both alveolar cortical plates, buccal and lingual/palatal, at the apical region causing communication between the flapped tissues (usually buccal) and the unflapped tissues (usually lingual/palatal). Multiple approaches have been proposed to manage these defects using different regenerative materials such as resorbable membranes with or without graft material, calcium sulfate, platelet-rich plasma (PRP) and platelet rich fibrin (PRF). However, there is no consensus on the ultimate management protocol for these defects, which leaves clinicians uncertain about the long-term prognosis. A possible reason for the different outcomes is the variation in how through and …

Attempting Heroics: Restoring Buccally Angulated Implants, Ryan Leong
Excellence Day
Buccally placed tissue-level implants in the esthetic zone may encounter various challenges, particularly concerning the trajectory of the screw channel and the implant body's placement. In this case, while addressing an edentulous space in the upper left quadrant with an implant bridge spanning from #12 to #14 it became evident that #12 was far too buccally placed. To address this issue, #14 was designed for screw retention, while #12 was planned for cement retention to accommodate the screw channel exiting through the buccal cusp. Although this method may seem to make the cement retained aspect of the restoration unretrievable, using …
