What Are Dental Implants?

A dental implant is a small titanium screw I place into your jawbone to replace the root of a missing tooth. Once living bone fuses to it, a process called osseointegration , I attach a crown on top. Three parts, no moving pieces: the implant is the root, the abutment is the connector, the crown is the visible tooth. When all three are placed correctly, it behaves as if it had always been part of your mouth.

Unlike the alternatives, an implant stands on its own. It doesn’t decay, it never needs a root canal, and it doesn’t require me to reshape the healthy teeth on either side the way a bridge does. If you want the head-to-head, I wrote out implants versus a traditional bridge and how they compare with dentures on their own pages. Already have a specific question, like cost or healing time? I answer the ones I hear most in the dental implants FAQ.

We’ve been placing osseointegrated implants for six decades, and the long-term data is something almost no other restoration can match. The ADA reports a 90 to 95 percent success rate over 10 years when placement protocols are followed; a 2024 meta-analysis in Clinical Oral Investigations still finds roughly 4 in 5 implants surviving at 20 years in well-maintained patients. With good hygiene and a balanced bite, the implant body itself routinely outlasts the crown on top of it.

An implant is three components that fit together into one tooth: the implant body (the root), the abutment (the connector), and the crown (the visible tooth). Each does a distinct job, and the material I choose for each one is a deliberate decision, not a default. If any of the terms below are new to you, I keep a plain-English glossary of every implant word you’ll hear at a consult.

The implant body. A medical-grade titanium screw, typically 8 to 14 mm long and 3 to 6 mm wide, placed surgically into the jawbone. Titanium earns its place for one biological reason: bone cells grow directly onto its surface. That said, titanium isn’t the only option, for the right patient I place metal-free ceramic instead, and I walk through which implant material is right for you in detail. For very narrow ridges, when mini implants make sense is its own conversation.

The abutment. A small connector that screws into the implant and protrudes through the gum. It’s the only part you might see in a mirror before the final crown is bonded. I use zirconia abutments when esthetics matter, because they avoid the gray shadow titanium can cast through thin gum tissue.

The crown. The visible tooth. My standard is full-contour zirconia: indistinguishable from a natural tooth, biocompatible, and covered along with the implant beneath it by my 10-year biological warranty. (I don’t, and no honest practice should, promise a “lifetime implant warranty.”)

Osseointegration is the biological event where living bone cells migrate directly onto the titanium and lock the implant in place. It’s not glue and it’s not a press-fit, it’s your own bone treating the implant as part of you. Once it’s complete, the bond is mechanically stronger than the original tooth root, which is the whole reason an implant can carry a chewing load for decades.

The phenomenon was discovered by accident in the 1950s, when a researcher found he couldn’t remove titanium chambers from bone after a few months, the bone had fused to them. The AAID dates the first documented titanium osseointegration in a human jaw to 1965, and that single observation is the foundation of everything I do.

In the body, the process takes roughly 8 to 14 weeks in the lower jaw and 12 to 18 weeks in the upper jaw, where bone is less dense. During that window the implant rests undisturbed. Here’s the part most patients never hear: those first three months are the only window where osteoblasts lay down fresh bone against the implant, so the surgery decides most of the outcome, closer to 70 percent of it, in my hands, with the years of care afterward making up the rest. That’s also why I plan the full implant procedure, step by step, around protecting that early bone.

I push that integration as hard as biology allows with my Vampire Implants™ Protocol: UV photofunctionalization of the implant surface, paired with platelet-rich plasma drawn from your own blood and layered onto the implant before I seat it. UCLA research on UV-activated implants shows 50 to 100 percent more bone-to-implant contact, with better blood flow and a stronger infection response, which is what lets me treat diabetics and smokers other offices turn away.

Survival just means the implant is still in your mouth. Success is something I hold to a stricter standard: a band of hard, keratinized gum forming a real seal around the collar that locks bacteria out, with near-zero bone loss underneath. When that seal holds, the bone doesn’t move. I have patients more than ten years out with zero measurable bone loss, that’s what I’m aiming for every time.

The number I actually watch, year over year, is marginal bone loss , how much bone, if any, recedes around the collar. A fixture that’s technically still in place but slowly losing bone isn’t a success to me; a sealed, stable implant with healthy gums is. If you want the full picture of what the success rate really measures, I broke it down by year and by case type on its own page.

An implant scales from one missing tooth to a whole arch. The biology is the same; what changes is how many implants share the load and how they brace one another, I lay out every type of dental implant and the case it fits on its own page, but here is the short version.

A single tooth. One implant, one crown, the most common case. I do these in two visits spread across about four months: one to place, one to crown. A lone implant can occasionally be the trickier case, because no neighbors brace it against side-to-side force.

Several teeth in a row. Two implants can support a three- or four-unit bridge, which avoids crowning the healthy teeth on either side. Splinted together, implants move far less and are stronger than any one standing alone.

A full arch. Six implants can carry a full set of fixed teeth, what I call All-on-6. The arch is bolted in: no adhesive, no removal, no slipping. I favor six over four because the implants brace each other in all three dimensions, and I build the bridge on a hidden titanium bar so a crack can’t travel through the zirconia and so chewing force is distributed evenly across every implant, front to back.

Because an implant preserves what the alternatives sacrifice: your neighboring teeth, and the bone in your jaw. A bridge buys time; an implant solves the problem at the root. Here’s the trade-off in plain terms, and you can read the full case for implants if you want it.

A traditional bridge requires me to grind down the healthy teeth on either side of the gap. Those teeth are lastingly weaker afterward, and a meaningful share will need a root canal down the line from the trauma of being reshaped. An implant leaves the neighbors completely untouched, the full comparison lives on my implants-versus-bridges page.

Dentures sit on the gums. Without a root to stimulate it, the jawbone underneath gradually resorbs, you lose the most bone width in the first year alone, which is why dentures that fit at delivery stop fitting a few years later and need relining or replacement. An implant stops that loss because it acts like a real root.

The honest cost of choosing an implant is upfront time: about three to four months from placement to final crown, versus a couple of weeks for a bridge. I think the longer timeline is worth it. Patients who choose implants in their fifties rarely have to revisit the decision in their seventies, and if you’re weighing whether you’re a candidate, I walk through who qualifies and what to do if you’ve been told no.

A single implant at 5D Smiles is $3,500, all-inclusive, the consult, the 3D CBCT scan, the implant, the abutment, and the final zirconia crown. No add-on fees once the treatment plan is signed. A full arch (All-on-6) starts at $20,000 per arch with the bone graft included, and a dual arch at $40,000.

On longevity: the ADA puts 10-year success at 90 to 95 percent, and in the major long-term studies survival lands at 95 to 98 percent. At my practice the implant and crown together carry a 10-year biological warranty: if it fails biologically within those ten years, osseointegration, peri-implantitis, bone loss, I redo everything, surgery, parts, and lab, at no cost to you, the only condition being twice-yearly hygiene with me. I spell out exactly what the warranty covers and the two things it doesn’t in plain language. I warranty the biology because that’s the meaningful thing, modern materials make the parts themselves nearly indestructible barring accident.

The biggest variable in how long an implant lasts is the gum seal, and the two things that protect it are hygiene and your bite. Implants don’t decay, but the tissue around them can become inflamed, a condition called peri-implantitis that a 2022 systematic review in BMC Oral Health found affects roughly 19.5 percent of implant patients over time. Caught early on a routine exam, I can reverse it with a laser-assisted procedure that rebuilds the seal. The other quiet killer is force in the wrong direction: an implant has no ligament to cushion it, so I rebalance the bite at maintenance visits, almost like rotating the wheels on a car, axial force straight down the implant is fine, but the side-to-side load is what drives bone loss. Keep the seal sealed and the bite balanced, and how long implants actually last stops being a worry.
