Dental Implants

Single Tooth, Bridge, or Full Arch?

How implant number and configuration are chosen — from one missing tooth to a full smile.

6 min readMedically reviewed

The number of implants is a clinical decision, not a preference. It reflects bone volume, bite forces, aesthetics, and long-term maintenance.

Single-tooth

One implant, one crown. The most conservative option, and often the longest-lasting.

Implant-supported bridges

Two implants can support three or four teeth, avoiding the preparation of adjacent natural teeth.

Full-arch (All-on-4 and All-on-6)

Four to six precisely angled implants can support a fixed full-arch prosthesis, restoring a complete smile without a removable denture.

The maintenance conversation

More implants mean more surface area to clean. Every configuration demands a maintenance plan — professional and at home — designed for that specific case.
