I. Basic Information

Name: Mr. Guo

Gender: Male

Age: 49

Chief Complaint: The right maxillary central incisor became loose and exfoliated three days ago, affecting aesthetics and function; requesting implant‑supported restoration.

Past Medical History: Denies any systemic diseases, and no known food or drug allergies.

Present Dental History: The right maxillary central incisor exfoliated three days ago, affecting aesthetics, function, and mastication; presented to our clinic for consultation.

II. Clinical Examination

Intraoral Examination: The right maxillary central incisor was missing, with gingival recession noted. The lateral incisor also exhibited gingival recession, with calculus present mesially. The patient reported that a diastema had been present even before the loss of the central incisor.

Auxiliary Examination: Radiographic examination was performed.

III. Diagnosis and Treatment Plan

Diagnosis: Missing right maxillary central incisor with gingival recession.

Treatment Plan: Restoration‑driven approach using one Hanzu® implant (size 3.5 × 13 mm) with labial bone grafting.

IV. Treatment Procedure

Surgical Procedure: Calculus was removed, and the area was irrigated with hydrogen peroxide and disinfected. After incision and flap reflection, the labial bone defect was confirmed as consistent with the CBCT findings. A 3.0 mm trephine bur was used to harvest autogenous bone, and the osteotomy was prepared. One Hanzu® implant (3.5 × 13 mm) was placed following a restoration‑driven approach. A healing abutment (4.5 × 3 mm) was connected, and the harvested autogenous bone was grafted labially. The wound was sutured.

Follow‑up (Prosthetic Phase): At three months post‑operatively, osseointegration was confirmed to be satisfactory, and the definitive restoration was delivered.

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.
