Full-mouth All-on-4 rehabilitation with Straumann implants

Full-mouth All-on-4 rehabilitation with Straumann implants

Complaints:

Inability to chew food properly, reduced vertical dimension of occlusion, tooth mobility, bad breath, and an unesthetic smile.

Diagnosis:

Stage II–III periodontitis, acquired edentulism of the upper and lower jaws, impaired occlusal stability, and dysfunction of the stomatognathic system.

Treatment:

The diagnostic phase included CBCT imaging, a gnathological assessment, 3Shape intraoral scanning, and digital 3D treatment planning. Custom surgical guides were fabricated for full-mouth rehabilitation of both jaws using the All-on-4 concept. Under sedation, all hopeless teeth were extracted and eight Straumann implants were placed immediately according to the All-on-4 protocol. Temporary prostheses supported by titanium bars were delivered on the day of surgery, restoring both smile aesthetics and chewing function. After 6 months of successful osseointegration, the temporary prostheses were replaced with definitive zirconia restorations reinforced with custom titanium bars and screw-retained fixation. As a result, full oral function, TMJ performance, and smile aesthetics were successfully restored.

In this case, the patient was affected not only by missing teeth and the inability to chew properly, but also by severe consequences of periodontitis, including tooth mobility, reduced bite height, persistent bad breath, and a significant deterioration of smile aesthetics.

Preserving the remaining teeth and restoring function through localized treatment was no longer possible.

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

Under sedation, hopeless teeth were extracted and eight Straumann implants were placed immediately using custom surgical navigation guides.

Temporary fixed prostheses on titanium bars were delivered on the same day as the surgery.

Six months after osseointegration, the temporary restorations were replaced with permanent zirconia prostheses on custom titanium bars with screw retention.

Result:

The patient received fully restored dental arches, proper bite height, stable chewing function, and an attractive smile.

The treatment also helped normalize temporomandibular joint function and eliminate discomfort associated with periodontitis.

Even in severe cases of periodontitis and extensive tooth loss, successful rehabilitation is possible.
