Full-mouth All-on-6 rehabilitation with Straumann implants for periodontitis

Full-mouth All-on-6 rehabilitation with Straumann implants for periodontitis

Complaints:

Unesthetic appearance of the smile, tooth mobility in both the upper and lower jaws, and bad breath.

Diagnosis:

Generalized Stage III periodontitis, acquired secondary edentulism, and impaired functional balance of the stomatognathic system.

Treatment:

During the diagnostic stage, the patient underwent computed tomography (CT) and a gnathological assessment with analysis of jaw positioning. This evaluation revealed unstable occlusal contacts and helped determine the functionally optimal mandibular position for the future rehabilitation. Based on the diagnostic findings and digital 3D planning, full-arch rehabilitation of both the upper and lower jaws using the All-on-6 concept with Swiss Straumann implants was selected as the treatment approach. To ensure highly accurate implant placement, intraoral digital scanning of the jaws was performed using a 3Shape scanner, and custom surgical navigation guides were fabricated. The entire surgical procedure was carried out under intravenous sedation with continuous monitoring by an anesthesiologist, providing the patient with complete physical and emotional comfort throughout the extensive treatment. The procedure began with the atraumatic extraction of all teeth affected by periodontitis in both jaws, followed by thorough antiseptic treatment of the surgical sites and immediate placement of 12 implants. Immediately after surgery, an immediate-loading protocol was implemented by fixing temporary fixed prostheses reinforced with titanium bars, allowing the patient to restore esthetics and function on the same day.

In this case, the patient sought treatment due to severe periodontitis, tooth mobility, persistent bad breath, and significant impairment of smile aesthetics.

Due to extensive loss of supporting 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, a full rehabilitation of both jaws was planned using the All-on-6 concept supported by Straumann implants.

Custom surgical guides were fabricated to ensure precise implant placement.

Under intravenous sedation, the teeth affected by periodontitis were atraumatically extracted and 12 implants were placed immediately — six implants in each jaw.

Temporary fixed prostheses supported by titanium bars were delivered on the day of surgery according to the immediate loading protocol, allowing immediate restoration of smile aesthetics and chewing function.

Result:

The patient received fixed teeth in both the upper and lower jaws, restored chewing function, and an attractive smile.

The consequences of advanced periodontitis were eliminated, creating a stable foundation for long-term oral rehabilitation.

Even in severe cases of periodontitis, modern implant dentistry can restore teeth after complete tooth loss.
