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.
