Zirconia All-on-4
The Zirconia All-on-4 is a full arch solid zirconia All-on-Four implant restoration. This screw-retained implant solution is durable and esthetic, dramatically improving speech and function. The Zirconia All-on-4 attaches to the implants with titanium connections for optimal strength. The zirconia used in the Zirconia All-on-4 is made up of tiny, fine, round particles and when sintered at 1565ºC, the smallest particles are combined, creating a glassy, smooth non-porous surface. As a result, this restoration will not stain like traditional acrylic dentures and have little maintenance.

All-on-4: zygoma implants and quad zygoma Branemark initially developed zygoma implants for 3 primary reasons as his treatment modality for
(1) maxillary defect with post cancer (CA) resection,
(2) trauma,
(3) severe maxillary atrophy.
The concept of the zygoma implants is to use available bone at a distant site when locally insufficient.
The apex of the implant gets engaged to the body of the zygoma, transversing the maxillary sinus and emerging from the first molar position at a 450 angle categorizes the maxilla into 3 zones radiographically: zone 1 = premaxilla, zone 2 = premolar and zone 3 = molar.
The zygoma implants are indicated where there is insufficient bone in the premolar and molar regions, leaving only the anterior premaxilla available.
The implant configuration will be 2 axial implants in the anterior position and 2 zygoma implants in the posterior region. If there is absolutely no available bone in the maxilla, the Quad Zygoma uses 4 zygomatic implants to support fullarch prosthesis.
