Graftless treatment of the severely resorbed maxilla

Featured Products Promotional Features

  Posted by: The Probe      4th November 2018

Severe maxillary resorption often requires extensive grafting procedures, lengthening treatment time and increasing discomfort for the patient.

However, by anchoring in the zygomatic bone, the NobelZygoma implant system from Nobel Biocare makes the immediate loading protocol possible for a graftless solution.

Designed to achieve high primary stability,[i]the NobelZygoma implant features an unthreaded implant body that interfaces with the soft tissue and can be placed outside the maxillary sinus (where clinically appropriate). The implant head can be located close to the crest of the alveolar ridge, facilitating a prosthetic procedure than improves cleaning ability, patient comfort[ii]and phonetics.[iii]

Not only does the NobelZygoma implant help clinicians avoid complex and time-consuming bone-grafting procedures, but remarkable survival rates have also been demonstrated – with one study finding an average survival rate of 95.12% after 10 years.[iv]
