We studied the stress-strain state of the bone tissue and maxillary full-arch fixed implantretained denture. Load was applied to the anterior (150 N) and posterior (250 N) parts of the denture supported by 6 or 4 implants, including zygomatic ones and placed by on-all-4 treatment technology. The obtained stress values in the bone tissue, implants, and denture show a large strength margin of structural materials. At the same time, the bone strength values were low, especially around the zygomatic and distal implants of all-on-4-implants-supported dentures when the posterior part of the denture was under load.
