Implant vs bridge vs denture Periodontal treatment

Dental implants, bridges and dentures all replace missing teeth; they differ in surgery, effect on the neighboring teeth, upkeep and time to finish. In a systematic review, implant-supported crowns survived at 89.4% after ten years. Conventional bridges survived at 89.2% over the same period.

Is an implant better than a bridge or denture?

An implant leaves the neighboring teeth untouched and helps preserve the jawbone, while bridges and dentures are finished sooner.

	Implant crown	Bridge	Removable denture
Neighboring teeth	Untouched	Enamel removed for the support crowns	Partial dentures clasp onto them
Jawbone	Implant helps preserve bone	Jaw shrinks where the tooth was lost	Jaw shrinks under the denture
Survival	89.4% at 10 years	89.2% at 10 years	95.1% at 5 years (partial)
Upkeep	Maintenance visits; screw loosening 8.8% in 5 years	Decay and nerve loss in support teeth	Reline every 1 to 2 years
Time to finish	6 to 12 months	Lab work of 2 to 4 weeks	Several fitting visits

Cleveland Clinic states that implants help preserve existing bone and that the jawbone gradually shrinks after tooth loss. Ask your periodontist to price and time each option for the specific gap. Timelines are set out in the implant process, and jawbone changes from gum disease in bone loss.

When is a bridge better than an implant?

A bridge fits when healthy natural teeth stand on both sides of the gap, as Cleveland Clinic describes for traditional bridges. Preparing those teeth removes enamel, and that step is irreversible. A systematic review of fixed prostheses placed conventional bridges with a support tooth at each end, implant-supported bridges and single implant crowns as first options.

Other designs did less well. Cantilever bridges, held from one side, survived at 80.3% after ten years. Bridges joining implants to natural teeth survived at 77.8% over the same time. That review placed both designs as a second option, for anatomy or patient preference. The most frequent problems with conventional bridges were biological: decay and loss of nerve vitality in the support teeth. A bridge is also quicker, since the lab usually needs 2 to 4 weeks to make it. Bring these questions to the consultation with the questions to ask list, and see dental implants for the implant side.

When is a denture the right choice?

A denture fits when several, most or all of the teeth in a jaw are missing. Cleveland Clinic describes complete dentures that replace a whole arch and partial dentures that clasp onto the remaining teeth. A systematic review of removable partial dentures found 95.1% survival after five years for cast-clasp designs. Support teeth carried a higher risk of extraction after five years, with an odds ratio of 1.99. The review found few periodontal changes in the remaining teeth.

Complete dentures last 7 to 10 years on average, according to Cleveland Clinic. The same source advises a reline every 1 to 2 years and notes that many wearers find their dentures shift or slip when speaking or chewing. Implant-retained dentures typically offer more stability than traditional dentures, according to the same source. The McGill consensus names a two-implant overdenture the first-choice standard of care for the toothless lower jaw. Options are set out in full-arch implants and implant dentures.

Does a bridge or denture cause bone loss?

Jawbone loss begins when a tooth is removed, before any bridge or denture is fitted. Re-entry studies measured the ridge six months after extraction. By then it had lost 29% to 63% of its width. Its height had dropped 11% to 22%. Most of the change came early, followed by gradual loss after that.

Cleveland Clinic states that the jawbone gradually shrinks following tooth loss, which can lead to sunken-in cheeks in denture wearers. The same source lists jawbone preservation among the benefits of implants. A graft at extraction, called socket preservation, may reduce the change, though a Cochrane review rated that evidence very uncertain. A ridge that has already narrowed can be rebuilt with ridge augmentation before an implant. The American Academy of Periodontology describes ridge modification as filling the void where bone is missing with bone or a bone substitute.

How long does each tooth replacement take?

Bridges and dentures take weeks; implants take months. A tooth-supported bridge usually needs 2 to 4 weeks in the lab, then a second visit to fit it. Some offices make bridges in a single appointment with CAD/CAM milling. Dentures need several office visits to reach the right fit. Getting used to new dentures can take weeks or sometimes months, according to Cleveland Clinic.

Implant treatment takes 6 to 12 months in total at Guy's and St Thomas' NHS Foundation Trust. A bone graft can add 4 to 6 months. Implant-supported bridges take longer than tooth-supported bridges because the implants must fuse with the jaw first. Cleveland Clinic puts that fusion at 3 to 6 months on average. An immediate implant can shorten the wait, and how long treatment takes covers the rest of periodontal care.

Questions

Is a dental implant more expensive than a bridge?

Implants usually cost more than bridges and dentures. Cleveland Clinic describes bridges as more affordable than dental implants and states that implants are typically more expensive than dentures. Ask for a written estimate that lists each stage, including any extraction, bone graft, implant, abutment and crown.

Can a bridge be supported by implants?

A bridge can rest on implants in place of natural teeth. Cleveland Clinic describes implant-supported bridges for three or more missing teeth in a row. In a systematic review, bridges supported only by implants survived at 86.7% after ten years. The natural teeth beside the gap are not prepared for this design.

What is a Maryland bridge?

A Maryland bridge, or resin-bonded bridge, holds a false tooth with wings bonded to the backs of the neighboring teeth. A systematic review found 82.9% survival after ten years. Debonding was the most frequent complication, at 15% over five years. Bridges with a single retaining tooth and those with zirconia frameworks had the highest survival.

Can you switch from dentures to implants later?

Implants can be added for denture wearers at any adult age once the bone and general health allow; Cleveland Clinic sets no upper age limit. The jaw keeps shrinking under a denture, so a bone graft or sinus lift may be needed first. Two implants can hold a lower denture as a snap-in overdenture.

Do implants feel like natural teeth?

Cleveland Clinic states that implants work much like natural teeth once healed and that most people eventually forget the implant is there. Implant-retained dentures typically offer more stability than traditional dentures because they snap onto implants, according to the same source. After a bridge, the teeth and gums take one to two weeks to heal on average, and the bridge can take a little longer to feel natural, according to Cleveland Clinic.
