In September 2025 the BBC ran a 4D facial scan and an X-ray of a 41-year-old woman from Telford. Her name is Leanne Abeyance. She is a working DJ and a mother of two. In April 2024 she paid roughly £3,000 to a clinic in Antalya for full-mouth extractions, 13 implants, bilateral sinus lifts, bone graft, and veneers. Eighteen months later, two of those implants were sitting in her sinus and nasal cavity, her septum had collapsed, and a soft-tissue infection was eating through the floor of her nose. The image the BBC chose to publish was the scan, not the smile. That is the right image to publish, and this piece is about why.
I wrote about the Turkey teeth phenomenon two days ago and argued that the dominant story — peg teeth, debonded crowns, post-preparation pulpitis — is real but is masking the more dangerous failure mode. The Abeyance case is the cleanest example of that more dangerous failure mode I have seen in mainstream UK reporting. It is on a national broadcaster, with imaging the public can read, with a named patient, with a documented timeline, with a remediation cost in the tens of thousands. There is no editorial reason to keep referring to this category of complication in the abstract when the BBC has published a scan of it.
This piece reads the Abeyance case clinically, places it inside the published evidence on dental-tourism complications, and explains what the underlying decision was that produced it. The conclusion is not “don’t go to Turkey.” The conclusion is that the posterior maxilla is an anatomy that punishes time pressure and rewards CBCT, and that a clinic offering 13 implants and bilateral sinus lifts in a single trip is making a clinical promise the anatomy will not always honour.
What the BBC actually showed
The Abeyance case has been covered by the BBC, LBC, and IBTimes UK. The clinical facts are consistent across the reporting:
- All natural teeth extracted at one Antalya clinic across the visit window.
- Thirteen implants placed — seven upper, six lower.
- Bilateral sinus lift performed at the same visit, with a particulate bone graft.
- Veneers fitted to a temporary prosthesis.
- Total Turkish cost: approximately £3,000.
- Domestic UK quote for the same scope of work, prior to the trip: approximately £50,000.
After the procedure she returned home. Within months she was in constant facial pain, breathing through one nostril, and presenting with recurrent purulent sinus infections. Imaging in the UK — including a 4D facial scan — showed two of the upper implants had been driven through the floor of the maxillary sinus and into the nasal cavity. The septum had collapsed. The soft tissue around the nasal aperture was necrotising. By the time the BBC ran the segment in September 2025 she had spent roughly £2,000 on private dentistry trying to find someone willing to take the case. The remediation quote — surgical removal of the displaced implants by a maxillofacial team, soft-tissue reconstruction, and prosthetic rehabilitation — exceeded £45,000.
That is the scaffold of the case. The clinical reading underneath it is more specific.
The anatomy the price hid
The maxillary sinus is the largest of the paranasal sinuses and it sits directly above the roots of the upper premolars and molars. In a young patient with all teeth present, the sinus floor and the alveolar crest are separated by a few millimetres of cortical and trabecular bone. When upper posterior teeth are lost, the sinus pneumatises — it expands downward into the space the roots used to occupy. Within five years of extraction, residual vertical bone in the second-molar position can be 2–4 mm. In some patients it is less.
This is not an exotic finding. It is what every implantologist sees on every CBCT of an upper posterior edentulous segment. Pjetursson and colleagues’ 2008 review of sinus floor augmentation describes the population at length: the sinus pneumatises, the ridge resorbs, and any plan to place a fixture longer than the residual bone height has to do something about the gap between the planned apex and the sinus floor.
The legitimate options are well-known:
- Place a shorter implant. Modern short fixtures (6 mm and 8 mm) are engineered for low crown-to-implant ratios and have peer-reviewed survival rates statistically equivalent to longer implants placed with sinus augmentation. The 2016 Lemos meta-analysis of 19 randomised studies is the foundational reference here. A 6 mm implant in 7 mm of bone is a routine, evidence-supported choice.
- Tilt the implant. Anchor it in remaining bone anterior to the sinus, angled distally to support a posterior occlusal unit. The Del Fabbro 2012 review of 1,958 tilted implants reports 97.6% one-year and 96.8% three-year survival.
- Lift the sinus floor. A staged procedure: lateral window or transcrestal approach, careful elevation of the Schneiderian membrane, particulate or block graft, six-month healing, then fixture placement. In experienced hands with proper case selection, complication rates are low. The procedure has good evidence behind it. The question is never whether it works. The question is whether the clinic doing it has the imaging, the technique, the time, and the case-selection discipline to do it well.
Sinus lift is not the problem. The decision that produced the Abeyance case is the problem.
What goes wrong, and why this case is the textbook of it
A sinus lift performed at a high-volume cosmetic clinic, on a patient whose treatment plan was agreed without an in-person CBCT review, on a timeline compatible with a one-week dental holiday, in conjunction with twelve other implants placed on the same trip, is operating outside the conditions under which the procedure has its published safety record. The Abeyance images show what happens when those conditions break down.
Two specific things go wrong in this category of failure, and both are visible on the imaging the BBC published.
The Schneiderian membrane is perforated and not repaired. The membrane is the thin epithelial lining of the sinus floor. A sinus lift requires elevating it without tearing it; small tears can be patched intra-operatively if recognised. A torn and unrecognised membrane means the graft material communicates with the sinus cavity, the bone does not consolidate, and the implant placed into the augmented site has nothing to anchor into. In the Abeyance scan, the soft-tissue inflammation tracking from the implant fixtures up into the nasal cavity is consistent with this pattern — graft material and oral flora communicating with a sinus that should have been sealed.
The implant is placed with a length and angle that the residual anatomy could not accept. This is the geometric error. If the available bone height is 4 mm, a 13 mm implant must either pierce the sinus floor or stop short of full insertion. If the angle of placement does not respect the curvature of the maxilla, the apex of the implant exits the bone envelope altogether and ends up in the soft tissue beyond. In the Abeyance case, two implants ended up in the nasal cavity. That is not a marginal sinus communication. That is a fixture placed at an angle the bone could not support, in a position the clinical imaging — if it had been reviewed — would have flagged.
The reason these errors compound in the high-volume tourism context is not Turkish anatomy. The reason is time. A sinus lift performed on day one, with thirteen implants placed across the same trip, with veneers prepared and fitted before the patient flies home, is a procedural sequence that ignores the standard six-month healing period the published protocols specify. The graft does not consolidate. The fixture is loaded before integration. The membrane heals or doesn’t heal in conditions the surgeon never sees because the patient is on a flight.
What the published evidence says about how often this happens
The Abeyance case is not a one-off. It is a high-profile instance of a well-documented pattern.
The British Dental Association’s 2022 member survey found that 86% of UK dentists had treated complications from dental tourism in the preceding year. The British Dental Journal’s 2025 review of 131 UK newspaper articles between 2018 and 2023 found that complications coverage was almost entirely Turkey-centric, with crowns and implants the two top failure categories, and remediation costs ranging from £500 to over £5,000 in 20% of cases. The BDJ’s 2025 clinical aftermath piece describes specific case findings: five teeth tender to percussion in a single returnee, periapical pathology requiring multiple endodontic interventions, and the medico-legal complexity of restoring crowns the patient cannot identify the brand of.
The General Dental Council told BBC Newsnight in February 2023 that it had received over 300 formal complaints about Turkish dental work in a single year. The Turkish Dental Association, quoted in Euronews in 2022, self-reports a 3–5% botched-surgery rate against a patient flow of 150,000–250,000 international patients per year. That arithmetic produces 4,500–12,500 complication cases annually by the industry’s own figures. The Abeyance scan is one of those, made visible.
The implant subset of these cases — the cases in the posterior maxilla where the failure is geometric and the rescue is maxillofacial — is a smaller fraction of the total. It is the fraction with the highest morbidity per case, the longest remediation pathway, and the lowest probability of complete recovery. It is also the fraction the press tends to under-cover, because it does not photograph as well as a peg tooth.
The BBC chose to publish the scan. That choice is what makes this case useful.
What the patient could have known
I want to be careful here. Hindsight is the easiest clinical posture in dentistry, and the patient who agreed to this treatment did so under conditions she could not, from the outside, evaluate. The structural argument the publication has made in the trust gap piece applies: a patient cannot verify, from a clinic’s website, the things that determine whether her sinus lift will perforate or hold.
There are three things she could nevertheless have asked.
A pre-operative CBCT, read by the treating clinician, before the treatment plan was agreed. Not after she landed. A CBCT taken in the UK and shared with the Antalya clinic, or a stipulation that no surgical plan would be confirmed until on-site CBCT was reviewed in her presence, would have provided the imaging on which the geometric decision rests. A clinic that agrees a thirteen-implant plan based on an emailed panoramic radiograph and a photograph of the patient’s smile is a clinic operating without the imaging the procedure requires.
A timeline that respected the biology. A sinus lift requires approximately six months of healing before fixture placement. Thirteen implants in a maxilla that has lost most of its posterior bone will, in a clinic operating to published protocols, be a 9–14 month treatment plan with multiple visits. A clinic offering the same scope of work in a single trip is offering a timeline the procedure cannot accommodate. The veneers fitted at the end of the same visit are the giveaway: the prosthetic outcome was sequenced to the patient’s holiday, not to the biology of the graft.
A written aftercare protocol, with a named domestic contact, before she paid the deposit. This is not glamorous. It is the question that distinguishes a clinic with a complication-management infrastructure from one without. “If something goes wrong after I land back in Birmingham, what happens?” If the answer is “fly back to Antalya” or “see your local dentist,” the answer is that there is no aftercare protocol. Dental Protection’s practice guidance for UK dentists managing the fallout describes precisely the position UK clinicians find themselves in when these cases arrive: high complication management burden, no records, no implant identification, no continuity, no indemnity from the original treating clinic.
A patient who asks all three questions and receives unsatisfactory answers to any of them is being told something important about the clinic’s operating model. The clinic in Antalya, on the public record, did not provide answers to any of them. The patient could not have known, before she went, what the answers would be. That is the trust gap, applied to her case.
What changes the clinical picture
The publication’s standing position on Turkey is in the Turkey teeth piece and applies here. Geographic warnings are not a clinical framework. There are competent clinics in Turkey, and the failure pattern documented in the Abeyance case is replicable in any country where high-volume cosmetic clinics, throughput economics, and short-trip timelines combine. The reason the cases concentrate in Turkey for UK patients is that Turkey is the dominant destination for UK patients. That is not the same as Turkey being the cause.
The clinical picture would revise downward — meaning the publication’s assessment of the posterior-maxilla failure mode in Turkish dental tourism would soften — if any of the following appeared:
- A peer-reviewed cohort study from a registered Turkish prosthodontic or oral-maxillofacial surgical programme, reporting five-year sinus-lift success rates and implant-related sinus-complication incidence in a high-volume international patient population, with methodology that allows independent verification.
- A major Turkish dental tourism platform publishing, voluntarily and publicly, its own complication rate data, including sinus-related implant displacement, post-operative sinusitis, and remediation outcomes.
- Regulatory action by the Turkish Dental Association that establishes minimum CBCT documentation, sinus-lift case-volume thresholds, and aftercare protocol requirements for clinics serving international patients, with verifiable enforcement.
None of these currently exists. The 3–5% complication rate the Turkish Dental Association acknowledges is an aggregate without sub-category granularity. The peer-reviewed Turkish cohort data on sinus complications in international patients does not appear in any database I can search. In the absence of that evidence, the BBC’s published scan of Leanne Abeyance’s nasal cavity remains the clearest visual record we have of what this category of case looks like, and the BDJ aftermath piece remains the cleanest peer-reviewed description of the clinical pattern.
What good posterior-maxilla implant care actually looks like
For the patient considering implants in the upper back jaw — in Turkey, in Vietnam, in Hungary, in Australia — the framework is the same one set out in the bone grafting decision piece, with a posterior-maxilla-specific extension.
Pre-operative CBCT, read in the patient’s presence, with the clinician walking through the residual bone height in millimetres, the sinus floor topography, and the planned fixture length and angle. If the available bone is below 5 mm and the proposed solution is a same-trip sinus lift with immediate fixture placement, the patient is being offered a procedure that the published evidence does not support at that timeline.
A documented consideration of short and tilted implants. The 6 mm fixture is not a compromise; it is a peer-reviewed alternative. If the treatment plan does not contain a “considered and ruled out” line for short and tilted options, the plan has not been worked up. It has been quoted.
A staged timeline if augmentation is genuinely indicated. Four to six months of graft consolidation before fixture placement, eight to twelve weeks of osseointegration before loading, prosthetic finalisation after that. If the clinic is fitting veneers on the same trip the implants are placed, the prosthetic outcome is being sequenced to the holiday, not to the biology.
A written aftercare protocol naming a domestic contact and a complication pathway, signed before the deposit. If a complication arises after landing, the patient is not lost in the trust gap.
A clinician with documented specialist training in sinus floor augmentation, and a case volume sufficient for the procedure to be routine in their hands. The procedure has a learning curve. The published complication rate in experienced hands is not the rate that applies to a clinician doing one a week between cosmetic packages.
These are not exotic conditions. They are what a competent posterior-maxilla case looks like. The patient’s job is to ask whether the clinic she is considering meets them. The publication’s job is to give her the framework to ask.
What I would tell Leanne Abeyance if she walked into my surgery tomorrow
I would tell her that the case in front of me is not the dentistry that was promised on the website she booked from. The dentistry was a quote and a brochure. The case is a patient with two displaced implants in the nasal cavity, a perforated sinus, a collapsed septum, and a necrotising soft-tissue infection. Those are different objects. The first one is a marketing problem. The second one is a maxillofacial problem.
I would tell her that the remediation pathway involves surgical removal of the displaced fixtures by a hospital-based oral-maxillofacial team, soft-tissue and septal reconstruction, sinus drainage and antibiotic management, and only then a long, careful conversation about whether her bone and soft tissue can support a future prosthesis at all. The £45,000 quote she has been given is consistent with that pathway. It is not inflated.
I would tell her that the case will produce a defensible peer-reviewed write-up at some point, if a UK maxillofacial unit chooses to publish it, and that the BBC’s decision to broadcast the scan was the right one, because the visual record changes how the next patient evaluates the same offer.
I would tell her that she is not stupid. She booked a procedure on the information available to her, and the information available to her was not the information she needed. That is the structural failure this publication exists to name.
The patient considering thirteen implants and bilateral sinus lifts on a one-week trip to Antalya, or anywhere else, should have read this piece before she paid the deposit. If she has, and she still goes, that is her decision. If she has not, and she goes anyway, the publication has done what it can. The framework is here. The case is on the BBC. The scan is in evidence. Go informed, or don’t go.
