Full-arch prostheses that are permanently affixed to four to six dental implants are known as fixed hybrid dentures. The prosthetic teeth may only be taken out by a dentist for maintenance or repairs; you cannot take them out at home. Fixed hybrids often cost more and take longer from planning to final implantation since they require more implants and more complicated surgery. They work well for you if you desire a secure, non-removable option and if your jaw bone and overall health allow for several implants.
With detachable attachments that let you to remove the denture for cleaning, overdentures require fewer implants. Snap-in (ball-retained) and bar-retained systems are typical attachments. Two or more implants and tiny studs that click into the denture are used in snap- in (ball) attachments. A metal bar that joins many implants and clips on for more robust support is used in bar-retained overdentures.
Fixed hybrids are screwed or glued to a fixed prosthesis and often need four to six implants. The prosthesis is not taken off every day. The goal of implant placement for hybrids is to distribute implants across the arch in order to distribute chewing loads and preserve the health of the jawbone. A fixed hybrid will require fewer regular removals, but cleaning beneath the prosthesis will require expert access.
