Full upper jaw rehabilitation with All-on-6 MegaGen AnyRidge implants

Full upper jaw rehabilitation with All-on-6 MegaGen AnyRidge implants

Complaints:

Complete absence of teeth in the upper jaw, impaired chewing ability, difficulty eating hard foods, esthetic concerns, and intermittent discomfort and tension in the temporomandibular joints (TMJs).

Diagnosis:

Secondary edentulism of the upper jaw. Reduced vertical dimension of occlusion. Disturbed occlusal relationships. Functional disorders of the temporomandibular joints.

Treatment:

The diagnostic phase included CBCT imaging, 3Shape intraoral scanning, occlusal analysis, and a gnathological assessment. Based on the findings, digital 3D implant planning was performed and a customized surgical guide was fabricated. Under general anesthesia, full rehabilitation of the upper jaw was completed using the All-on-6 concept with MegaGen AnyRidge implants. A temporary fixed prosthesis reinforced with a titanium bar was delivered on the day of surgery according to the immediate loading protocol, restoring both smile aesthetics and chewing function immediately. After 6 months of successful osseointegration, a definitive zirconia restoration reinforced with a custom titanium bar and screw-retained fixation was placed. The treatment restored proper occlusion, improved TMJ function, and achieved a stable aesthetic result.

In this case, complete tooth loss in the upper jaw resulted not only in impaired chewing function and smile aesthetics but also in a reduced vertical dimension of occlusion, creating additional stress on the temporomandibular joints.

Therefore, special attention was paid to gnathological assessment and occlusal analysis before treatment.

Following CBCT imaging, 3Shape digital scanning, and 3D treatment planning, upper jaw rehabilitation was performed using the All-on-6 protocol with MegaGen AnyRidge implants.

To ensure precise implant placement, an individual surgical navigation guide was fabricated.

A temporary fixed prosthesis on a titanium bar was delivered on the day of surgery, allowing the patient to immediately regain chewing function and smile aesthetics.

Six months after successful osseointegration, the temporary restoration was replaced with a permanent zirconia prosthesis on a custom titanium bar with screw retention.

Result:

The upper dentition, proper vertical dimension of occlusion, chewing function, and smile aesthetics were fully restored.

It was also possible to normalize occlusal relationships and improve temporomandibular joint function.

When all teeth are missing, it is important to restore not only the smile but also the proper function of the entire stomatognathic system.
