Full-mouth All-on-4 rehabilitation with Neobiotech implants for periodontitis

Full-mouth All-on-4 rehabilitation with Neobiotech implants for periodontitis

Complaints:

Esthetic defect, missing teeth, difficulty biting food, and tooth mobility.

Diagnosis:

Generalized Stage II–III periodontitis affecting both the upper and lower jaws, impaired occlusal stability, and functional imbalance of the stomatognathic system.

Treatment:

During the diagnostic stage, a computed tomography (CT) scan and a gnathological assessment were performed to analyze jaw relationships, determine a functionally stable mandibular position, and predict the occlusal balance of the future restorations. Based on the collected data, 3D treatment planning, intraoral scanning with a 3Shape scanner, and fabrication of custom surgical navigation guides for both jaws were completed. The surgical stage was performed under sedation. Following the atraumatic extraction of all teeth affected by periodontitis, Neobiotech implants were placed immediately according to the All-on-4 protocol using surgical navigation guides. Temporary fixed prostheses supported by titanium bars were delivered immediately after surgery, allowing the patient to fully regain esthetics and chewing function on the same day. After 6 months, successful osseointegration and soft tissue stability were confirmed. The temporary restorations were replaced with permanent zirconia prostheses reinforced with custom titanium bars and secured with screw-retained fixation. This approach restored functional balance of the stomatognathic system, improved temporomandibular joint function, and achieved a stable esthetic outcome in both jaws.

In this case, the patient's concerns included tooth mobility, missing teeth, and a significant deterioration in smile aesthetics caused by severe generalized periodontitis.

Due to the extensive destruction of the periodontal tissues, preserving the remaining teeth and restoring function with conservative treatment methods was no longer possible.

Following CT imaging, gnathological diagnostics, 3Shape digital scanning, and 3D treatment planning, full rehabilitation of both jaws using the All-on-4 concept was selected.

Under sedation, atraumatic tooth extraction was performed for teeth affected by periodontitis, followed by immediate placement of Neobiotech implants using custom surgical guides.

Temporary fixed prostheses on titanium bars were secured on the day of surgery, immediately restoring smile aesthetics and chewing function.

After 6 months of successful osseointegration, the temporary restorations were replaced with permanent zirconia prostheses on custom titanium bars with screw retention.

Result:

The dental arches of both jaws, chewing function, smile aesthetics, and proper occlusal relationships were restored.

The patient received stable fixed restorations and regained comfort in everyday life.

Even in cases of severe periodontitis and multiple tooth loss, modern treatment protocols can provide successful rehabilitation in complex clinical situations.
