Dental implant removal is a well-defined surgical procedure that oral surgeons and periodontists perform when an implant has failed, fractured, or is causing ongoing tissue damage. The technique your clinician chooses depends largely on how firmly the implant is still attached to bone: early failures, where the implant never fully integrated, can sometimes be backed out with simple hand instruments, while late failures involving a partially or fully integrated implant call for more involved approaches like reverse-torque devices, trephine burs, or piezoelectric cutting. The goal in every case is the same: get the implant out while preserving as much surrounding bone and soft tissue as possible so the site can heal or accept a replacement implant later.
When Does an Implant Actually Need to Come Out
Implants fail for several broad reasons, and the timing of that failure changes both the difficulty of removal and the urgency behind it. Early failures happen within the first weeks or months, typically because the implant never achieved stable integration with the jawbone. Overheating during the initial surgery, contamination of the surgical site, or poor bone quality can all prevent the bone from locking onto the implant surface. These implants tend to be mobile and relatively straightforward to remove.
Late failures are a different story. The most common culprit is peri-implantitis, a progressive inflammatory condition that destroys bone around an otherwise integrated implant. Implant fracture and malpositioning round out the list of frequent late-failure causes.1Japanese Dental Science Review. Treatment strategies for dental implant removal: A literature review Because these implants are still at least partly bonded to the bone, they resist simple unscrewing and require more aggressive surgical techniques.2PubMed Central. Removal of failed dental implants revisited: Questions and answers
Deciding whether to remove versus attempting to salvage a struggling implant is not always obvious. When peri-implantitis is involved, clinicians weigh multiple factors: how many implants are affected, where the implant sits within the remaining bone, the shape of the bone defect around it, what kind of restoration sits on top, and the patient’s overall health.3PubMed.

If the implant is visibly mobile or its prosthetic superstructure cannot be maintained, removal becomes the clear path forward.1Japanese Dental Science Review.

Imaging and Pre-Surgical Planning
Before any removal attempt, your clinician needs a detailed picture of what is happening beneath the gumline. Standard dental X-rays, panoramic images, and cone-beam computed tomography (CBCT) each contribute different information. A two-dimensional X-ray might confirm bone loss around the implant threads, while a CBCT scan gives a three-dimensional view of the remaining bone envelope, the proximity of nerves and sinuses, and the extent of any defect.4PubMed Central. Imaging technology in implant diagnosis The imaging choice depends on the specific diagnostic question: is there enough bone for a replacement? How close is the implant to the nerve that provides feeling to your lower lip? Is the implant fractured below the bone surface? These answers drive the surgical plan.
For straightforward cases where peri-implantitis has already loosened the implant, a periapical X-ray and clinical probing may be sufficient. Complex scenarios, like a fractured implant deep in a posterior jaw near the inferior alveolar nerve, almost always call for a CBCT scan to map safe margins for cutting instruments.
How Implants Are Physically Removed
Four main techniques dominate the literature on implant explantation, and they sit along a spectrum from conservative to aggressive in terms of how much bone they sacrifice.
Reverse Torque
This is the least invasive option. A specialized wrench or ratchet grips the internal connection of the implant and applies rotational force in the opposite direction from how the implant was placed. Think of it like unscrewing a bolt. A systematic review covering hundreds of removed implants found reverse torque was the most frequently reported technique, used on about 284 implants, with a success rate of roughly 88%. The reviewers considered it the most conservative approach and recommended it as the first choice despite its lower success rate compared to more aggressive methods.5PubMed. Removal of osseointegrated dental implants: a systematic review of explantation techniques When it works, it spares almost all surrounding bone.
A lab study comparing four removal techniques found that counter-torque ratchet technique produced the least bone loss of any method tested, significantly outperforming trephine burs and conventional burs in both weight and volume of bone removed.6PubMed Central. Comparison of Four Different Dental Implant Removal Techniques in Terms of the Weight and Volume of Bone Loss The limitation is that reverse torque only works when the implant’s internal connection is intact and accessible. A fractured implant or one with a stripped connection defeats this approach.
Trephine Bur
When reverse torque fails or isn’t possible, a trephine bur is the traditional fallback. This is a hollow, cylindrical drill that cores out a ring of bone around the implant, freeing it from the surrounding tissue. It is highly effective because it physically severs the bone-implant bond regardless of how well integrated the implant is. The trade-off is obvious: it removes a meaningful cylinder of bone along with the implant. Among the techniques studied, trephine burs caused significantly more bone loss than either counter-torque or piezoelectric methods.6PubMed Central. Comparison of Four Different Dental Implant Removal Techniques in Terms of the Weight and Volume of Bone Loss
Conventional Bur
A high-speed or surgical bur can be used to cut bone away from the implant surface. This provides good access and control, but like the trephine, it sacrifices bone. It also generates heat, which can damage remaining bone cells and compromise healing. In the same comparative study, conventional burs fell between trephine and piezoelectric instruments in the amount of bone lost.
Piezoelectric Surgery
Piezosurgery uses ultrasonic vibrations tuned to cut mineralized tissue while leaving soft tissue largely unharmed. The key advantages are precise, selective cutting and avoidance of thermal damage to surrounding structures.7PubMed Central. Piezosurgery in implant dentistry Because the ultrasonic frequency acts only on hard tissue, the risk of damaging nerves, blood vessels, or the gum tissue is significantly reduced compared to rotating burs.8PubMed. Piezosurgery applied to implant dentistry: clinical and biological aspects In the bone-loss comparison study, the piezoelectric technique and counter-torque were the only pair that did not show a statistically significant difference in bone loss by weight, suggesting piezo is nearly as conservative as reverse torque when the latter isn’t an option.6PubMed Central. Comparison of Four Different Dental Implant Removal Techniques in Terms of the Weight and Volume of Bone Loss
In practice, clinicians often start with reverse torque and escalate to piezoelectric or trephine instruments only if needed. Combination approaches are common: a piezoelectric tip might loosen the coronal portion of bone contact, and then reverse torque finishes the job.
Why Bone Preservation Matters So Much
The bone that surrounds your implant is the foundation for everything that comes next, whether that is a replacement implant, a bridge, or a removable denture. When implants are removed, the ridge of bone inevitably shrinks. A retrospective study of patients who had implants removed due to peri-implantitis found that ridge width decreased by about 11% at 1 mm below the crest and about 4% at 3 mm below. Ridge height dropped on both the cheek side and the tongue side.9PubMed. Hard tissue dimensional changes following implant removal due to peri-implantitis: A retrospective study
The same study found two factors that minimized those losses. First, using a reverse-torque removal kit appeared critical in limiting ridge changes compared to more aggressive techniques. Second, performing bone grafting at the time of implant removal, rather than letting the site heal on its own, reduced ridge width loss by about 12% and cheek-side height loss by about 5% compared to spontaneous healing.9PubMed. Hard tissue dimensional changes following implant removal due to peri-implantitis: A retrospective study The practical message: if you want the best foundation for a future implant, the decisions made during the removal surgery itself set the trajectory for what is possible later.
Current protocols for post-removal site reconstruction are guided by the shape and size of the resulting bone defect. Minimally invasive removal methods based on reverse-torque engineering are now considered key to preserving both hard and soft tissue, and implant replacement at previously failed sites has become a realistic option given high survival rates of second implants placed in these locations.10Periodontology 2000. Management and sequelae of dental implant removal
Can You Get Another Implant in the Same Spot
Yes, and the evidence is reasonably encouraging. One study that tracked patients who received a new implant after a failed one was removed found that about half had the replacement placed immediately, while the other half waited an average of roughly two and a half months. There was no significant difference in failure rates between immediate and delayed replacement. The overall failure rate for the second implant was about 12%, and all of those patients went on to receive a third implant that survived to the end of follow-up.11PubMed. Prognosis of the implants replaced after removal of failed dental implants
Those numbers are worth putting in context. A second implant at a previously failed site carries a somewhat higher failure risk than a first-time implant placed in healthy bone. But a 12% failure rate still means that nearly nine out of ten replacement implants survived. Whether your clinician recommends immediate or delayed replacement depends on the bone quality at removal, whether grafting was done, and whether any active infection has resolved. If peri-implantitis destroyed a large volume of bone, a staged approach with grafting and a healing period of several months is the safer bet.
Bisphosphonates and Medication-Related Concerns
If you take bisphosphonates for osteoporosis or other bone conditions, implant removal carries an additional layer of concern. Bisphosphonates suppress the normal turnover of bone, which means the jaw’s ability to heal after surgery is compromised. A large cohort study found that bisphosphonate users had a modestly increased risk of needing implant removal compared to non-users. Among those on bisphosphonates, higher cumulative doses were associated with a progressively higher risk of removal, and the route of administration mattered: intravenous bisphosphonates were actually linked to a somewhat lower removal risk than oral ones.12PubMed. Consequence of Bisphosphonate Use on Dental Implant Removal in Osteoporotic Patient: A Nationwide Cohort Study
The bigger worry for bisphosphonate patients is medication-related osteonecrosis of the jaw, a condition in which exposed bone in the jaw fails to heal. Research has found that implant loading, meaning putting functional force on the implant with a crown or prosthesis, may be a stronger trigger for osteonecrosis than implant placement surgery itself.13PubMed Central. A clinical retrospective study of implant as a risk factor for medication-related osteonecrosis of the jaw: surgery vs loading? If you are on bisphosphonates and facing implant removal, your surgeon will likely coordinate with your prescribing physician about whether to temporarily pause the medication, though the evidence on “drug holidays” before oral surgery remains mixed. The key is that your clinician knows your full medication history before any procedure.
Broken Abutment Screws and Other Tricky Scenarios
Not every “implant removal” means taking out the whole fixture. Sometimes the problem is a fractured abutment screw stuck inside an otherwise healthy implant. This is a delicate procedure: the goal is to extract the broken screw without damaging the implant’s internal threads, which would require removing the entire implant.
Ultrasonic tips are widely used for this task. They vibrate at a frequency that loosens the screw fragment without the torque forces that might strip the internal connection. One concern with this approach is heat generation. A lab study found that using ultrasonic tips for screw removal produced an initial rapid temperature spike followed by a gradual decline.14PubMed Central. Removal of broken abutment screws using ultrasonic tip – a heat development in-vitro study In clinical practice, surgeons manage this with intermittent irrigation to keep temperatures below the threshold that would damage surrounding bone cells.
Subperiosteal implants, an older design that sits on top of the bone beneath the gum rather than inside it, present their own removal challenges. The procedure requires lifting the tissue away from the bone to expose the implant framework, then cutting the framework into smaller pieces for removal. Because these implants sit over a wide area and often near nerves, the risk of nerve injury and soft-tissue damage is higher than for conventional screw-type implants. After removal, the site typically needs thorough debridement and an assessment of how much bone remains for any future restoration.15PubMed Central.

Does the Implant Material Change the Removal Approach
Most dental implants are made of titanium or titanium alloy, and the vast majority of removal research focuses on these. Zirconia (ceramic) implants are a growing alternative, marketed for their white color and metal-free appeal. A meta-analysis comparing zirconia and titanium implants found that acid-etched zirconia surfaces actually achieved better bone contact than titanium, while machined zirconia showed no significant difference from titanium.16BioMed Research International. Effect of Zirconia Dental Implant Surfaces on Bone Integration: A Systematic Review and Meta-Analysis What this means for removal is that a well-integrated zirconia implant can be just as firmly locked into bone as a titanium one, and the same escalation from reverse torque to cutting instruments applies.
Zirconia does introduce one additional complication: it is more brittle than titanium. If excessive reverse torque is applied, there is a risk of fracturing the implant body, leaving fragments embedded in bone that then need to be retrieved with burs or piezoelectric instruments. For this reason, clinicians working with zirconia tend to have a lower threshold for moving to a cutting technique rather than pushing the limits of reverse-torque force.
What Recovery Looks Like
Recovery after implant removal resembles recovery after a tooth extraction, with some differences driven by the amount of bone work involved. If the implant came out with reverse torque alone and a bone graft was placed, you are looking at moderate swelling for a few days, manageable discomfort with standard painkillers, and a soft-food diet for a week or two. If a trephine or extensive piezoelectric cutting was required, the swelling and discomfort window tends to be longer because more tissue was disrupted.
Your clinician will typically prescribe antibiotics if infection was part of the reason for removal, and anti-inflammatory medication for the first several days. Smoking and alcohol both impair wound healing and are especially harmful during the early weeks when the bone graft, if one was placed, is beginning to incorporate. Most patients can return to normal activities within a few days, though the bone itself may need three to six months of healing before it is ready for a replacement implant, particularly if significant grafting was done.
Follow-up imaging at a few weeks and again at a few months helps your clinician track how the bone is filling in and decide whether the site is ready for re-implantation. The combination of conservative removal technique, simultaneous grafting, and adequate healing time gives the best odds of a successful second implant when you are ready to move forward.
