Why is this topic important for you?
You may have heard that there are differing opinions on this topic. This is because science is often more complex than a simple yes or no answer suggests. In this article, we explain what current research actually shows—without technical jargon and without omitting important details.
The topic is a service and management model, not simply a technological advantage.
Why is this important for you? Because as a patient, you can make better decisions if you understand the background. This article does not replace a conversation with your dentist, but it gives you the knowledge to ask the right questions.
In the research, the most important questions revolve around the following areas: control densification vs. clinical equivalence, patient selection and escalation logic, platform lock-in, and data workflow. In the following sections, we explain what the studies say about each of these areas and what that means for your daily life.
What matters more: Control Densification or Clinical Equivalence?
A common patient question is how to weigh control densification vs. clinical equivalence. The answer is not as simple as one might hope—but research is now providing clear indications.
The central question of this cluster is: Does more digital feedback actually lead to better clinical management—or just more data points without actionable consequences? Current scientific evidence provides a nuanced answer. Both existing systematic reviews (Sangalli et al. 2024; Torres et al. 2023) consistently show that dental monitoring significantly reduces the number of in-person appointments without worsening core clinical parameters—such as treatment duration, number of refinements, or emergency visits.
A summary of several studies by Torres et al. (2023) quantifies the reduction in in-person appointments to an average of 2.75 fewer visits in the monitoring group compared to the control group (mean difference −2.75; 95 % CI −3.95 to −1.55; I²=41 %; p<0.00001). At the same time, the pooled analysis shows no significant shortening of the total treatment duration (mean difference −0.41 months; I²=70 %; p=0.74). This means: monitoring streamlines the process but does not accelerate it. Clinically, this means that the gain is primarily in logistics, not in the treatment outcome itself.
The review by Sangalli et al. (2024) complements this picture with a broader study base, including 11 studies and a total of 542 patients. The reduction in in-person appointments ranged across studies from 1.68 to 3.5 visits. Additionally, there was a positive trend regarding aligner fit: During the retention phase, patients with monitoring showed significantly fewer retainer misalignments than controls (100 % vs. 66 %, P=0.027; Sangalli et al. 2021b). This finding is clinically relevant because it suggests that more frequent digital feedback can actually lead to better compliance and fit accuracy.
Nevertheless, the scientific evidence for true outcome equivalence remains limited. None of the included studies were scientifically controlled—all used clinical designs without random group assignment. The GRADE assessment by Torres et al. (2023) rates the reliability of the research findings as very low, mainly due to the risk of bias and the heterogeneity of the included studies. This does not mean that the direction of the signal is wrong, but the precision of estimating the effect remains limited. For practice, this means: remote monitoring can reduce in-person appointments without causing clinical disadvantages—but the equation 'fewer visits = equally good result' is currently a plausible hypothesis, not an established proof.
Methodologically, it must be noted that the included studies vary considerably in study design, follow-up period, and patient selection. This heterogeneity limits the comparability of results and explains why pooled effect estimates must be interpreted with caution. Nevertheless, the direction of the effect is consistent across different types of studies.
For transferability to the German-speaking care context, it is also relevant that a significant portion of the scientific evidence comes from Anglo-American or Scandinavian healthcare systems. Differences in reimbursement structure, treatment culture, and patient access can influence effect sizes without invalidating the basic statement.
For practice, this means: It is important to separate process gains from outcome equivalence. Remote monitoring demonstrably reduces in-person appointments, but this logistical advantage should not be automatically interpreted as clinical equivalence.
Clinical decisions should not be based on single studies, but rather on the overall direction of available scientific evidence. The scientific evidence is most consistent for the aligner area—here, the benefit is shown both in terms of appointment reduction and time to first refinement. For fixed appliances and interceptive treatments, the data basis remains too thin for reliable recommendations.
In daily practice, this means: The scientific evidence does not provide a one-size-fits-all answer, but rather a framework for individualized decisions. Patient-specific factors such as general health, compliance, individual risk profiles, and treatment preferences must be factored into the decision.
What does this mean for your next dental visit? The research findings help you better contextualize your dentist's recommendations and ask targeted questions if anything is unclear.
Science has intensively investigated this topic in recent years. Several scientific works contribute to the current assessment. It is important to understand that not every study has the same weight of evidence. Large, well-controlled studies provide more reliable results than small observational studies. The overall picture from these various studies is what we present to you here.

What does "patient selection and escalation logic" mean for me as a patient?
When it comes to patient selection and escalation logic, the research situation is clearer than many people think. Here you will learn what current studies actually show.
Remote monitoring does not fit every treatment or every patient equally—this is evident in the composition of the included studies. The strongest scientific evidence exists for adult aligner patients with moderate malocclusions (Hansa et al. 2020, 2021). For children and adolescents undergoing interceptive treatment (palatal expansion), the data basis is thin and the risk of bias is high (Kuriakose et al. 2019; Moylan et al. 2019). A blanket recommendation across all patient groups cannot be derived from this scientific evidence.
The studies on the interceptive area particularly illustrate the selection problem. Kuriakose et al. (2019) examined 20 patients with mixed or permanent dentition undergoing Hyrax palatal expansion and found no significant difference between monitoring modalities. However, the authors noted that challenges with image quality make using it difficult for certain patients. Moylan et al. (2019) confirmed in a pilot study with only 12 patients that measuring intercanine and intermolar widths via video scan is fundamentally comparable to plaster model measurements—provided the scan quality remains acceptable.
The question of escalation logic is not systematically investigated in any of the included studies. This is a critical gap: If monitoring reduces the number of in-person appointments, it must be defined what findings trigger an escalation to an in-person appointment. The only study that documents a concrete escalation case is the case report by Hannequin et al. (2020), where dental monitoring detected the loss of an orthodontic button and incorrect aligner fitting early on. This single case illustrates the potential but cannot establish a structured escalation logic.
For evaluating this cluster, it is crucial that patient acceptance in the existing data is consistently positive. In the prospective study by Hansa et al. (2018) with 159 patients, monitoring users rated usability at 4.31/5 and treatment benefit at 4.4/5 on a Likert scale. 71% of patients reported positive perception, and 43% preferred monitoring over office visits (Kuriakose et al. 2019). This acceptance data is clinically relevant, but it does not replace selection criteria. High satisfaction in a motivated study population says little about compliance in routine care.
Methodologically, it must be noted that the included studies vary significantly in study design, follow-up period, and population selection. This heterogeneity limits the comparability of the results and explains why pooled effect estimates must be interpreted with caution. Nevertheless, the direction of the effect is consistent across different study types.
For transferability to the German-speaking care context, it is also relevant that a significant portion of the scientific evidence comes from Anglo-American or Scandinavian healthcare systems. Differences in reimbursement structure, treatment culture, and patient access can influence effect sizes without invalidating the basic statement.
For practice, this means: The text requires selection and trigger logic. Orthodontists using remote monitoring need clear protocols for which patients are eligible, which findings require an immediate in-person check, and how responsibility is distributed between the patient and the provider.
The clinical decision should not be based on individual studies but on the overall direction of available scientific evidence. The benefit is best supported for cooperative adult aligner patients with manageable treatment complexity. For children, adolescents, and complex fixed treatments, there is a lack of scientific basis for a blanket recommendation.
In daily practice, this means: The scientific evidence does not provide a one-size-fits-all answer but rather a framework for individualized decisions. Patient-specific factors such as general health, compliance, individual risk profiles, and treatment preferences must influence the decision.

How do scientists arrive at these conclusions? They do not just evaluate a single study but examine many investigations simultaneously. This allows them to determine whether a result was random or if it is consistently confirmed. The existing studies already provide important clues, even if further research is desirable.

What does "platform lock-in and data workflow" mean for me as a patient?
One point that often causes uncertainty is platform lock-in and data workflow. However, science has made important progress in recent years.
A systematic finding across all included studies is the near-complete dominance of a single platform provider: All four studies in Torres et al.'s (2023) meta-analysis, as well as the majority of the eleven studies in Sangalli et al.'s (2024) review, use Dental Monitoring® as the telemonitoring method. This monoculture is no accident—Dental Monitoring® was the only commercially available AI-powered remote monitoring system for orthodontics at the time of most studies (Torres et al. 2023).
The workflow gains from the platform are visible in the data. The system allows patients to regularly take photos of their teeth using a patented cheek retractor, which are then analyzed by a movement tracking algorithm (Sangalli et al. 2024). Sangalli et al.'s (2024) review described that the system comprises three integrated platforms: a mobile app, a web-based Doctor Dashboard®, and the movement tracking algorithm. This integration can provide real efficiency gains—the consistent reduction in in-person appointments across multiple studies proves this.
At the same time, this platform lock-in means that the entire scientific basis for remote monitoring in orthodontics is de facto a scientific basis for a single commercial product. Torres et al. (2023) point out in their discussion that teledentistry can also be performed using photos and videos without a special retractor—however, these approaches were not systematically evaluated in the controlled studies. For clinical assessment, this means: The positive effects are tied to a specific ecosystem and cannot be easily transferred to alternative solutions.
The COI transparency in the included studies is unremarkable—both reviews report no author commercial conflicts of interest (Sangalli et al. 2024; Torres et al. 2023). Furthermore, the primary studies predominantly report no or academic funding sources. Nevertheless, the system risk must be named: If all scientific evidence is based on a proprietary product, a structural dependency arises that goes beyond individual COI disclosures. The clinical value of remote monitoring can only be robustly assessed when platform-independent comparative data are available.
Methodologically, it must be noted that the included studies vary significantly in study design, follow-up period, and population selection. This heterogeneity limits the comparability of the results and explains why pooled effect estimates must be interpreted with caution. Nevertheless, the direction of the effect is consistent across different study types.
For transferability to the German-speaking care context, it is also relevant that a significant portion of the scientific evidence originates from Anglo-American or Scandinavian healthcare systems. Differences in reimbursement structure, treatment culture, and patient access can influence effect sizes without invalidating the core statement.
For practice, this means: It is important to name both technological benefit and system dependency together. Orthodontists should be able to utilize the efficiency gains of digital monitoring but simultaneously understand the dependence on a single platform as a strategic risk.
The clinical decision should not be based on individual studies, but on the overall direction of available scientific evidence. For selecting a monitoring system, this means: The scientific evidence supports the concept of remote monitoring; it does not automatically validate any single product as superior.
In daily practice, this means: The scientific evidence does not provide a one-size-fits-all answer, but rather a framework for individualized decisions. Patient-specific factors such as general health, compliance, individual risk profiles, and treatment preferences must be factored into the decision.
What does this mean for your next dental visit? The research findings help you better contextualize your dentist's recommendations and ask targeted questions if anything is unclear.
What makes these results reliable? In medical research, the rule is: the more independent studies that arrive at the same result, the more certain the statement is. The type of study and the number of participants also play an important role. Large controlled studies with many participants provide more reliable results than small surveys.
