The Use of Leukocyte- and Platelet-Rich Fibrin During Immediate Postextractive Implantation and Loading for the Esthetic Replacement of a Fractured Maxillary Central Incisor

Figure 1. Clinical aspect of the fractured tooth. Figure 2. Radiographic aspect of the tooth before crown removal. Figure 3a and b. The fracture of the crown involved the buccal surface of the tooth at an infrabony depth of 3 mm.

Figure 4. The Ossean Intra-Lock tapered implant was inserted in the palatal alveolar crest. Figure 5. A straight titanium abutment was screwed into the fixture. Figure 6. The space between the implant and the labial bone was filled with granules of Gen-Os mixed with leukocyte- and platelet-rich fibrin (L-PRF). Figure 7. The bio-implant graft was protected by a L-PRF membrane punched onto the abutment post.

Figure 8a and b. A provisional crown was prepared and cemented on the abutment, adapting and compressing the leukocyte- and platelet-rich fibrin membrane. Figure 9. Clinical aspects of the cicatrization after 48 hr. Figure 10. Gingival maturation at 7 days. Figure 11. Tissue maturation after 3 months.

Figure 12a and b. A zirconia abutment replaced the provisional titanium abutment and a full ceramic crown was prepared. Figure 13. Tissue maturation after 6 months. Figure 14. Two years posttreatment, the restoration presents as stable and esthetic. The gingival collar has improved positioning, contour and thickness, representing continual maturation.
