Maxillary overdenture with immediate loading

Edentulous maxilla with limited bone height in the posterior region. Flapless guided surgery, placement of two Straumann® BLC implants ∅ 3.75 x 10 mm (at positions 12 and 22) and two Straumann® BLC implants ∅ 4.5 x 10 mm (at positions 14 and 24). Immediate fixed temporization was achieved using the patientʼs former denture, which remained in function for three months. Subsequently, considering the patientʼs presentation with a thin upper lip, high smile line, and vertical bone crest atrophy, a final metal-reinforced overdenture fixed on a Dolder bar was selected.
