All-on-6 lower jaw rehabilitation with Straumann BLX Roxolid implants

All-on-6 lower jaw rehabilitation with Straumann BLX Roxolid implants

Complaints:

The patient complained about the absence of teeth on the lower jaw after the preliminary removal of all teeth. He noted the impossibility of chewing food normally, impaired masticatory function, discomfort while eating and increased load on the temporomandibular joints. The aesthetic defect of the lower third of the face and the lack of stable fixation of prosthetics were also of concern.

Diagnosis:

Complete secondary adentia of the lower jaw. Atrophic changes in the bone tissue of the lower jaw. Occlusion disorders and reduced chewing efficiency with functional overload of the temporomandibular joints.

Treatment:

This clinical case required a multidisciplinary approach involving an implant surgeon, prosthodontist, and gnathologist. Due to the long-term absence of teeth, special attention was paid to the analysis of occlusion and temporomandibular joint function. Following a comprehensive diagnostic evaluation, including computed tomography (CT) and digital 3D treatment planning, full rehabilitation of the lower jaw using the All-on-6 concept with Straumann BLX Roxolid implants was selected. To ensure maximum accuracy, a custom surgical navigation guide was used. Six implants were placed in strategically planned positions, and a temporary fixed prosthesis with artificial gingiva was delivered immediately after surgery, allowing the patient to regain esthetics and masticatory function on the same day. Six months later, after successful osseointegration and confirmation of soft tissue stability, the temporary restoration was replaced with a permanent zirconia prosthesis reinforced with a custom titanium bar and supported by six implants. As a result, masticatory function was fully restored, occlusal relationships were normalized, and a harmonious esthetic smile was achieved.

In this case, long-term tooth loss in the lower jaw led not only to the inability to chew food properly but also to bite dysfunction, overload of the temporomandibular joints, and changes in the proportions of the lower third of the face.

Therefore, treatment required a comprehensive approach involving a gnathologist, implant surgeon, and prosthodontist.

After CBCT imaging and digital 3D planning, full rehabilitation of the lower jaw was performed using the All-on-6 concept on Straumann BLX Roxolid implants.

An individual surgical navigation guide was used for precise implant placement.

A temporary fixed prosthesis with artificial gum was secured on the day of surgery, allowing immediate restoration of aesthetics and chewing function.

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

Result:

Teeth in the lower jaw, chewing function, proper occlusal relationships, and smile aesthetics were restored.

The patient received a stable fixed restoration and the ability to eat comfortably without restrictions.

In cases of complete tooth loss in one jaw, modern implant protocols make it possible to restore function and aesthetics even with severe tissue atrophy.
