All-on-4 upper jaw rehabilitation with Straumann transsinus implants

All-on-4 upper jaw rehabilitation with Straumann transsinus implants

Complaints:

Loss of teeth in the upper jaw, aesthetic and chewing function issues.

Diagnosis:

Missing teeth in the upper jaw, atrophy of the alveolar ridge in the upper jaw. Secondary edentulism of the upper jaw.

Treatment:

Intraoral scanning with 3Shape was performed, and a surgical navigation template for implantation was created. Straumann implants were placed in the upper jaw following the All-on-4 concept. A temporary plastic prosthesis reinforced with a titanium bar was made. After 4 months, permanent prosthetics were done on the implants, with non-removable zirconia crowns reinforced with titanium bars. Due to complex bone conditions, the distal implants were placed through the sinus cavities (trans-sinus implant placement with vestibular access). MaxGraft bone substitute material was used, and the access to the sinus cavities was closed with Straumann membranes. This bone grafting approach allowed implants to be placed as distally as possible to prevent loosening of the non-removable structure.

In this case, tooth restoration on the upper jaw was complicated by severe bone atrophy and complex conditions in the area of the maxillary sinuses.

Therefore, standard implant placement was not enough.

For the patient, Straumann implantation was chosen using the All-on-4 concept with a surgical navigation template.

The distal implants were placed trans-sinusally — through the maxillary sinuses, to position them as distally as possible and create a more stable base for the future non-removable structure.

Additionally, bone grafting was performed using MaxGraft material and Straumann membranes to close the sinus access points.

This approach allowed implantation even with the complex anatomy of the upper jaw.

Result:

The patient received restored teeth on the upper jaw: initially with a temporary prosthesis on a titanium bar, and after 4 months — permanent non-removable zirconia restorations on the implants.

If the upper jaw teeth are missing and there is insufficient bone, restoration is still possible.
