This clinical case report aimed to investigate impact of a novel inner ferrule (IF) preparation around root canal on the subsequent esthetic restoration. Material and Methods: This clinical research involved a case report featuring endodontically treated teeth (ETT) restored using a newly developed ceramic post. Special drills (Edenta AG GmbH, Switzerland) were utilized for root canal preparation, involving horizontal preparation around the cervical portion of the root canals and post spaces. Experimental samples (ETT) were prepared with and without a 2mm IF preparation. The newly designed zirconia ceramic posts (TZ-3Y-SBE, Tosoh, Japan) were cemented with Multilink Automix (Ivoclar), upgraded with MultiCore (Ivoclar), and crowned with an all-ceramic zirconia crown (Zirkonzahn, Italy). Results: Our clinical case provided insights into a new type of all-ceramic aesthetic restoration of prepared teeth (ETT) with a new IF preparation design and a new zirconia post-core design. Conclusion: The novel horizontal IF preparation around the root canal was developed to accommodate the initial retentive coronal ring of the newly designed zirconia posts. The incorporation of IF preparation and coronal retentive rings within the zirconia post structure effectively enhances the fracture resistance of ETT. This new modern aesthetic rehabilitation in all restored teeth significantly reduces the severity of root fractures for excellent function and aesthetic restoration of ETT.
