Which dental prosthesis fits in which situation?
It is not preference that decides, but how many teeth are missing and what still carries.
The question „which dental prosthesis is the best“ has no general answer. It does have a very concrete one, though, as soon as the findings are on the table. This page sorts the most common starting situations and points to the matching detail page for each.
The four questions that decide almost everything
How many teeth are missing? One can be restored with a bridge or an implant. Several, spread across the jaw, argue for a removable solution.
Where are they missing? A gap at the end of the row has no rear neighbour – which rules out a classic bridge.
How firmly do the remaining teeth stand? With advanced periodontitis no abutment carries reliably. Then the gums are treated first, see Dental prostheses after periodontitis.
How much bone is there? That decides whether implants are possible without preparation – see Dental prostheses with little bone.
