how are radiographs taken for implant planning?
taken in different planes to give an idea of bone length in the mandible/maxilla
what other imaging (not radiographs) is used for implant planning?
CBCT
how is CBCT used for implant planning
2D cross section through the bone and 3D modelling around the ridges. Software is used to plan where the implants can go
CBCT has higher radiation so need to justify
what are surgical and radiographic templates?
Replica of current denture and holes where the implants should go, can put this in the mouth and drill through the holes to position the implants exactly where u planned to place them
