This case report details the comprehensive treatment of a 16-year-old female patient presenting with fractured maxillary central (#21) and lateral (#11) incisors. Tooth #21 required extraction due to extensive fracture. Following endodontic treatment of #11, a crown lengthening procedure was performed to establish sufficient clinical crown height for restorative purposes. This surgical procedure involved precise soft tissue management to achieve optimal gingival architecture and ensure adequate ferrule preparation on #11.
A three-unit zirconia fixed partial denture (FPD) was then designed and fabricated. The FPD design incorporated a modified ridge lap pontic for tooth #21, providing excellent esthetics and mimicking the natural anatomy. A crucial element of the design was an intra-radicular attachment on #11, providing strong retention and support for the FPD. The selection of zirconia ensured high strength, biocompatibility, and superior esthetics.
The meticulous fabrication process, including impression taking, model construction, wax-up, and final cementation, is described. Post-operative care instructions and long-term follow-up are also discussed. The successful restoration resulted in improved masticatory function, enhanced esthetics, and improved patient satisfaction. This case underscores the importance of meticulous planning and execution in complex restorative cases requiring a multidisciplinary approach. The positive outcome emphasizes the effectiveness of crown lengthening, intra-radicular attachments, and zirconia FPDs in restoring severely compromised anterior dentition.
