III. Diagnosis and Treatment Plan
Diagnosis: Missing right maxillary posterior tooth.
Treatment Plan: Restoration‑driven approach using two Hanzu® implants (sizes 4.0×8.5 mm and 4.5×8.5 mm).
IV. Treatment Procedure
Internal sinus floor elevation was performed with simultaneous bone grafting, followed by placement of two Hanzu® implants (4.0×8.5 mm and 4.5×8.5 mm).



Post‑operative panoramic radiograph was taken.


The prosthetic phase was initiated; healing was satisfactory.

A palatally‑biased incision was made to augment the buccal gingival thickness.

The impression was transferred, restorative abutments were connected, and the definitive crowns were placed.



A post‑placement panoramic radiograph was taken.

V. Case Summary
The Hanzu® implant system demonstrates excellent osseointegration. The sloped shoulder design allows for more favourable bone coverage over the implant, which is conducive to bone attachment and growth, thereby ensuring long‑term implant stability and facilitating favourable stress distribution.
