New paper proposes decision model for impacted mandibular canines
Bottom line
A new 2026 paper in the Nederlands Tijdschrift voor Tandheelkunde highlights just how limited the evidence base remains for impacted mandibular canines, a rare but clinically difficult eruption anomaly. Authors M. Gilijamse and M. Koning note that, unlike impacted maxillary canines, there are still no formal treatment guidelines for mandibular cases. Their article lays out a decision-making model to help clinicians choose among autotransplantation, surgical extraction, monitoring, or surgical exposure with orthodontic treatment. (ntvt.nl)
Why it matters: For veterinary dental professionals, the paper is a reminder that rare eruption disorders often force case-by-case decision-making when standardized guidance is lacking. Broader human dental literature suggests mandibular canine impaction and transmigration are uncommon, treatment outcomes are supported mostly by retrospective studies and case reports, and management depends heavily on tooth position, age, surrounding pathology, and whether orthodontic movement is feasible. Reviews also show extraction and surgical-orthodontic traction are the most commonly reported approaches, with autotransplantation reserved for selected cases. (pmc.ncbi.nlm.nih.gov)
What to watch: Expect continued interest in decision tools, earlier imaging-based diagnosis, and more published case series as clinicians try to build a stronger framework for these rare mandibular canine cases. (education.aaoinfo.org)

A newly published article in the Nederlands Tijdschrift voor Tandheelkunde puts a spotlight on impacted mandibular canines, a rare eruption problem that can be difficult to diagnose and even harder to manage. In “Anomalous eruption of a mandibular canine,” M. Gilijamse and M. Koning argue that clinicians still lack dedicated guidelines for these cases, and they propose a decision-making model built around four main options: autotransplantation, surgical extraction, monitoring, or surgical exposure followed by orthodontic treatment. The article was published October 6, 2026, in volume 133 of the journal. (ntvt.nl)
That gap in guidance is the key backdrop here. Impacted canines are a familiar issue in dentistry overall, but most of the literature, protocols, and training emphasis have focused on maxillary canines rather than mandibular ones. The Dutch paper explicitly contrasts the two, noting that while upper canine impaction has clearer clinical pathways, lower canine impaction remains a rarer condition without an established guideline. (ntvt.nl)
The wider literature supports that framing. A systematic review on impacted and transmigrated mandibular canines found that the condition is rare and that published evidence is limited, with treatment approaches most commonly involving extraction or surgical exposure with orthodontic traction. Another recent review in the orthodontic literature similarly noted that only a small number of studies report treatment outcomes for mandibular canine impaction or migration, and those studies are largely retrospective. (pmc.ncbi.nlm.nih.gov)
That matters because treatment decisions can be highly individualized. Across the literature, the choice between monitoring, extraction, orthodontic traction, and autotransplantation turns on several practical factors: the patient’s age, the impacted tooth’s angulation and position, the presence of ankylosis or root dilaceration, proximity to adjacent roots, and whether pathology such as cyst formation or infection is present. Case-based and review literature also suggests that tooth-preserving strategies, including TAD-assisted orthodontic eruption and autotransplantation, can work in selected patients, but they require careful case selection and interdisciplinary planning. (pubmed.ncbi.nlm.nih.gov)
There doesn’t appear to be a major public press release or broad industry statement attached to the Dutch publication, but the surrounding professional conversation points in the same direction: earlier diagnosis and better planning may improve options. Orthodontic education materials and conference programming from the American Association of Orthodontists continue to emphasize imaging, risk management, and autotransplantation protocols for impacted teeth, while recent case presentations have focused specifically on early diagnosis and traction of impacted mandibular canines. That’s not the same as consensus guidance, but it does suggest growing clinical attention to the problem. (www2.aaoinfo.org)
Why it matters: For veterinary professionals who follow comparative dental and craniofacial research, this paper is useful less as a definitive protocol and more as a structured framework for rare-case decision-making. When formal guidelines are absent, a decision model can help teams communicate risk, weigh preservation against extraction, and explain options clearly to a pet parent facing a complex dental recommendation. It also underscores a broader lesson that applies across species: uncommon eruption abnormalities can demand coordinated imaging, surgery, and long-term follow-up rather than a one-size-fits-all plan. (ntvt.nl)
What to watch: The next step for this area is better evidence, especially prospective case series and outcome reporting that compare orthodontic traction, extraction, and autotransplantation in similar mandibular canine cases. Until then, clinicians will likely keep leaning on imaging-heavy assessment, interdisciplinary planning, and practical decision tools like the one proposed in this 2026 paper. (ntvt.nl)
