When several neighbouring teeth are missing, placing an implant for every single tooth is not always necessary. An implant-supported bridge uses a smaller number of implants as anchors for a fixed bridge that fills the whole gap. It offers the stability of implants without relying on natural teeth for support, and without the inconvenience of a removable partial denture.
Typically two implants are placed at either end of the gap, and a bridge with three or four teeth is attached to them. The middle teeth are supported by the implants rather than by their own roots. The bridge is screwed or cemented in place and cannot be removed by the patient.
A traditional bridge needs healthy teeth on both sides of the gap to support it, and those teeth must be reshaped for crowns. An implant-supported bridge does not involve the neighbouring natural teeth at all, protecting them from extra load and preparation. It is also an option when there is no natural tooth at one end of the gap.
Removable partial dentures are less expensive, but they can move, trap food, put pressure on gums and natural teeth, and need to be taken out for cleaning. Implant bridges feel and function much more like natural teeth, with better chewing efficiency and no clasps visible when you smile.
A 3D scan is used to plan the number and position of the implants. Depending on bone levels, grafting may be needed first. Once implants are placed, they are left to integrate for several months, during which a temporary may be worn. The final bridge is then made and fitted.
Implant bridges need careful cleaning underneath, using interdental brushes, superfloss or a water flosser, to prevent inflammation around the implants. Regular professional maintenance and check-ups help keep the implants and gums healthy for many years.
Often two implants can support a three or four-tooth bridge, but it depends on the size of the gap, bone quality and bite forces.
It is fixed in place and cannot be removed by the patient, though your dentist can remove it for maintenance if needed.
Usually yes, because fewer implants are needed to replace the same number of teeth.
