OBJECTIVE: To clinically evaluate the effect of the application of a Zirconia biovolume combined with surgical crown lengthening in patients with altered passive eruption, vertical maxillary excess, and excessive gingival display.
CLINICAL CONSIDERATIONS: Three systemically healthy patients (two female, one male) presenting altered passive eruption (APE) Type 1 Subtype B with vertical maxillary excess (VME) and gingival display > 5 mm were treated with a protocol consisting in the preparation of a Zirconia biovolume to be applied in the anterior maxilla at the same time of surgical crown lengthening. Intra and extra oral scans were taken, as well as CBCT and printing of stereolithographic models in order to study the cases, plan the fabrication of the biovolume, and plan the surgical crown lengthening. Patients were followed for up to 12 months. Healing was uneventful in all three cases, and all patients were satisfied with the esthetic outcome in terms of surgical crown lengthening, gingival exposure, and lip repositioning.
CONCLUSION: These three cases show how the planning of cases with excessive gingival display, VME, and APE can be treated with a planned surgical procedure that will at the same time solve the problem of gingival exposure and the position and support of the upper lip.
