The platform is showing! Prosthetic management of implants placed too far coronally

Fig. 2: An implant in site No. 4 was placed with its platform at the level of the gingiva on the facial. The cover screw extends supragingivally.





Fig. 3: The implant restoration at the bisque bake stage. A full ridge lap has been created on the facial.





Fig. 4: The try-in of the restoration at the bisque bake stage reveals inadequate coverage of the platform at the mesial-facial line angle. Additional porcelain will be added.




Fig. 5: The final restoration shows the full extent of porcelain that must be added to conceal the implant platform.





Fig. 6: The final restoration in place. Although the porcelain flange creates a minor esthetic discrepancy by making the tooth appear longer than the adjacent teeth, it is a superior choice to leaving the metal of the implant platform exposed.
