Present Dental History: Mobility of maxillary anterior teeth affecting mastication; presented to our clinic for consultation.

II. Clinical Examination

Intraoral examination was performed.

Radiographic examination was performed.

III. Diagnosis and Treatment Plan

Diagnosis: Mobility of maxillary anterior teeth with periapical abscess and labial alveolar bone resorption.

Treatment Plan: Restoration‑driven approach for the left maxillary (or maxillary anterior) sites, using three Hanzu® implants: one implant (size 3.5 × 15 mm) and two implants (size 4.0 × 13 mm).

IV. Treatment Procedure

Under local anaesthesia, the involved teeth were extracted immediately, and the osteotomy sites were prepared. A mixture of autogenous tooth bone graft and collagen was placed labially to augment the bone defect. Three Hanzu® implants were placed according to the pre‑planned positions.

In April 2025, the prosthetic phase was initiated, and the definitive restorations were delivered.

V. Case Summary

This case involved immediate implant placement at infected extraction sites with purulent discharge, in a patient with osteoporosis and inflammatory infection. The Hanzu® implant system demonstrated strong self‑tapping capability, leading to a favourable clinical outcome.
