Extremely narrow alveolar ridge at #24 as well as severe bone resorption at teeth #26–27 (left).

Tooth extraction #26 and #27 and preparation of a sinus window at #26. Ridge split at #24 as well as insertion of three implants at #24, 26 and 27 (right).

5 MONTHS POST-OPERATIVE

Optimal bony consolidation in the previously augmented horizontal dimension #24–27 (left) and in the augmented sinus areas #26–27 (right).
