D6118 — Implant/abutment-supported interim fixed denture, edentulous arch (mandibular)
One of the codes covering full-arch and partial-arch dentures supported by implants. D6118 is the version for the lower jaw.
This code belongs to a set of eight covering implant-supported denture. The clinical detail lives in the implant-supported denture guide; the code-level detail is here.
Four things follow: the conditions, the cost, the coverage, and the difference between this code and each one it sits beside.
The conditions built into D6118
Arch — lower. The bone is denser, but there is far less surface area to support anything removable and the nerve running through the jaw limits how aggressive surgery can be.
Status — interim, not definitive. It is built to function for a limited period while something else is planned or healing, and many plans fold its fee into the definitive restoration if that follows within a few months.
D6118 against the codes beside it
D6117 — Implant/abutment-supported fixed denture, partially edentulous arch (mandibular): It is the definitive version.
D6119 — Implant/abutment-supported interim fixed denture, edentulous arch (maxillary): It is the upper-jaw version.
D6116 — Implant/abutment-supported fixed denture, partially edentulous arch (maxillary): It is the upper-jaw version.
D6115 — Implant/abutment-supported fixed denture, edentulous arch (mandibular): It is the definitive version.
D6118 sits in a group of eight codes in total; the remainder are linked at the foot of this page. The safest question to ask is not "what does this cost" but "which code is going on the claim". The first answer changes; the second decides the first.
Every code in this group
These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.

Questions about D6118
What procedure is D6118?
D6118 records implant/abutment-supported interim fixed denture, edentulous arch, mandibular — one of the implant services codes.
How much does D6118 cost?
Between $2,000–$5,000 in most practices — and that is the figure before any benefit is applied, not what you would pay at the desk.
Is D6118 a covered benefit?
Plans generally pay it as major treatment, 0–50%, subject to whatever is left of your maximum for the year.
What is the difference between D6118 and D6117?
D6117 is implant/abutment-supported fixed denture, partially edentulous arch, mandibular: it is the definitive version. Apart from that, the two describe the same treatment — which is why the notes for the visit matter more here than the code itself.
Also known as: implant denture, snap-in denture, All-on-4, full arch implants, overdenture.
