The number of missing teeth is only the start
One implant can support one crown, while two or more implants can support a bridge replacing several teeth. The optimal design depends on bone, space, tooth position, bite and cleaning access.
Preserving adjacent teeth
An implant restoration can avoid preparing neighbouring teeth for a conventional bridge, but it requires surgery and adequate bone. If adjacent teeth already need crowns, a tooth-supported bridge may still be discussed.
Hygiene and force distribution
Implant bridges need room for interdental cleaning. Long spans and strong bite forces require careful design. A plan should consider the opposing teeth and whether the patient grinds.
Plan for maintenance
Ask how the restoration is attached, which components are used, how it can be repaired and how hygiene will be reviewed. More implants do not automatically mean a better or easier-to-maintain result.
