Aesthetic Correction of a Root Fracture Using an Implant-Supported Zirconia Restoration
Tony Aherne, MDS, DRD, RCS Ed
Upon reviewing this case study, the reader should:
- Be able to visualize the process of utilizing implant-supported restorations to correct root fractures
- See how new materials and techniques have increased dentists' ability to create more aesthetically pleasing results for patients
The use of implant-supported restorations has demonstrated significant success over the past two decades. As techniques and methods for implant placement continue to evolve, so too do the materials utilized for aesthetic implant rehabilitation. Discolored margins and opaque crowns can be easily avoided using durable all-ceramic options that provide optimal biocompatibility and aesthetics, while ensuring optimal function and load resistance.
While materials and techniques may have evolved over the years, patient considerations remain constant. The clinician is consistently challenged to maintain soft tissue contours and develop a scalloped appearance throughout the provisionalization phase to ensure acceptable fit and integration. Implant restorations placed adjacent to natural teeth must in no way vary from the natural teeth or surrounding restorations to ensure continuous harmony.
A 38-year-old female patient presented with a fractured root in the right central incisor and preexisting crown restorations that required replacement. As a result of the root fracture there was some loss of buccal bone. The existing crown had been in place for ten years and demonstrated compromised aesthetics. In order to maintain natural-looking translucency in the anterior region, an implant system with a reactive surface was used with an all-ceramic, zirconia abutment was selected to provide optimal aesthetics and strength. An immediate provisionalization protocol was utilized to ensure optimal tissue maintenance and to develop an aesthetic emergence profile.
