My ceramic implant has fractured or feels loose: what happens next?

First, find out what has actually broken

An implant tooth has three parts: the implant body in the bone, a connector (the abutment) and the crown you see. In a one-piece ceramic implant, the body and the connector are made as a single piece; in a two-piece design, the connector attaches with a screw or cement. When something cracks or feels loose, the problem may sit in any of these parts, or in the bone that holds them, and the fixes are not interchangeable:

• A chipped or cracked crown. The implant underneath may be perfectly sound. The crown can often be repaired or remade.
• A loose crown or abutment. On a two-piece design, a screw can loosen or the cement seal can fail. Tightening, re-cementing or replacing the connector is usually a restorative repair, not surgery.
• Bone loss around an unbroken implant. Peri-implantitis, an inflammatory disease of the gum and bone around an implant, can cause soreness, bleeding and bone loss even when nothing has broken, and advanced bone loss can leave the whole implant loose. Its treatment is about infection and bone, not about the ceramic.
• A fracture through the implant body. The ceramic post itself has cracked, which may be at or below the gum line. A fractured implant body generally cannot be glued or screwed back together, and the conversation turns to removal and replacement.

Only an examination can sort these out. The dentist will look for a visible fracture line, test whether the movement comes from the crown, the connector or the whole implant, probe the gum for bleeding or pus, and take X-rays. A 3D scan may be added when the fracture line or the bone level is unclear.

How urgent is it?

Most cracked or loose implant parts are urgent in the sense of "soon", not "tonight". The exceptions are swelling, trauma and bleeding, which follow the same rules as any other dental emergency.

Breathing or swallowing difficulty, rapidly spreading facial or neck swelling, fever with facial swelling, uncontrolled bleeding or severe trauma go to emergency care (call 911 or the nearest emergency department), not to an appointment request form. The guide Facial swelling with tooth pain: when emergency medical care comes first explains these signs in more detail, and Tooth pain tonight: what information helps your dentist decide urgency covers what to tell the office when you call.

Why zirconia behaves differently from titanium

Zirconia is a very strong ceramic, but it is brittle: it resists bending and wear well, yet when it does fail it tends to crack rather than bend. Titanium, a metal, deforms before it breaks. That difference is why "fracture" appears in zirconia implant research as a specific failure mode worth studying.

The reassuring part is that clinical reviews describe implant-body fracture as uncommon. In a 2023 systematic review and meta-analysis of about 4,000 zirconia implants, a minority of all failures were fractures, and most of those involved narrow-diameter implants. The same review found lower survival for implants whose upper part had been ground with a drill to adjust the shape, and for two-piece designs compared with one-piece designs. Laboratory testing points the same way: fracture resistance depends on the implant's design, the material formulation and whether the connector was modified after manufacture, with untouched connectors outperforming ground ones. A review of anterior zirconia implants also lists surface treatment, diameter and bite load among the mechanical factors implicated in fracture.

Heavy bite forces matter too. Tooth grinding and clenching are associated with more mechanical complications in implant-supported restorations, and the ADA notes that grinding can damage teeth and that a mouth guard can protect them, which is why a night guard is often part of the conversation after any implant repair. None of this means zirconia is a poor choice; ten-year survival in the 2023 review was high. It means the risk factors are specific, and a fracture is a reason to ask which of them applied to your implant. The guide Ceramic versus titanium dental implants: compare evidence, design, and fit compares the two materials in more depth.

What the examination checks

Which part failed

The first question is mechanical: is the movement in the crown, the connector or the whole implant? A crown or screw problem is usually a repair. A fracture line that runs into the implant body changes the plan entirely.

Bone level and infection

X-rays show how much bone surrounds the implant and whether it has receded. Bleeding or pus on gentle probing suggests peri-implant disease. The American Academy of Periodontology distinguishes peri-implant mucositis, which is confined to the soft tissue and is usually reversible, from peri-implantitis, which involves bone loss and often needs surgical treatment. Infection can be the cause of looseness, a consequence of a crack that lets bacteria in, or both.

Bite and grinding

The dentist checks how the implant tooth meets its opposing tooth, whether it takes a heavier load than its neighbors, and whether there are signs of grinding such as flattened or chipped teeth. A fracture without an obvious cause may have a bite or grinding explanation, which is why these checks are part of the examination.

Can the implant body be left?

A sound, integrated implant with a broken crown can usually be restored again. A fractured body usually cannot, and the discussion turns to how it will be removed and what replaces it. That is an individual decision made after imaging, not a rule.

If the implant body itself has fractured

When the implant must come out, the method matters for what happens afterward. A systematic review of explantation techniques describes several approaches, including reverse-torque instruments that unscrew the implant, trephine drills that cut a ring of bone around it, and piezoelectric or laser-assisted removal, with peri-implantitis the most common reason for removal, followed by bone loss and fracture. Techniques that remove less bone leave more to work with for a replacement, so it is reasonable to ask which method is planned and why.

After removal, the usual options are:

• Heal, then place a new implant. The socket is allowed to heal, sometimes with a bone graft to rebuild the width or height lost to infection or to the removal itself. The new implant may be ceramic again or titanium; the choice depends on what caused the first fracture, the space available and your preferences.
• A bridge supported by neighboring teeth. Avoids further surgery at the site but involves preparing the adjacent teeth. The guide Implant or bridge for one missing tooth: what changes the decision walks through that trade-off.
• A removable partial denture. A reversible option, sometimes used as an interim tooth while the site heals.
• No replacement for now. Reasonable for some back teeth if the bite is stable, with the understanding that the bone and gum at an empty site can change over time, which may limit later implant options.

What determines the choice is the amount of bone left after removal, whether infection has cleared, the condition of the neighboring teeth, your bite and grinding habits, and your tolerance for another healing period. If grinding contributed to the fracture, a protective night guard is likely to be recommended whatever option you choose.

Who treats it, and what to bring

A general dentist can usually make the first assessment, including the X-rays and the test of which part is loose. Depending on what is found, removal and regrafting, treatment of peri-implantitis, or a new implant may be handled by the same dentist or involve a periodontist, an oral surgeon or a prosthodontist. Ask the office which parts of your care would be done in-house and which would involve a referral.

Bring whatever records you have: the implant card or any paperwork naming the implant system and size, previous X-rays or a 3D scan, and the name of the office that placed it. Knowing the exact system is particularly useful for a two-piece design, because replacement screws and connectors are specific to it. If you cannot find the records, the previous office can usually supply them.

Ask for a written plan that names the failed part, the proposed fix and the alternatives considered. The guide What a written dental treatment plan should explain describes what that document should contain, and Dental implants in Santa Barbara: what should a complete consultation include covers the assessment before any new implant.

The next step

Loul Dental Studio lists computer-guided implant placement, including metal-free ceramic implants, among its services, and lists digital and 3D X-rays and a bite assessment among its check-up services. If a ceramic implant has cracked or feels loose, you can request an appointment through the practice's online request page or call (805) 565-5111 during office hours, Monday to Thursday, 8:00 am to 5:00 pm. Say that an implant has fractured or is loose, mention any pain or swelling, and ask how soon an assessment can be arranged. A request is not a confirmed appointment; the team follows up. Any of the emergency signs above means emergency care first, then the dental office.
