Clear aligners are incredibly popular and have provided millions of people with improvements to their teeth’s positioning and appearance. But while most people have positive treatment outcomes, this isn’t always the case. Now, a research team has sought to create a standardized approach that can increase the chances of all patients receiving excellent treatment outcomes.

Clear aligners continue to grow in popularity and are becoming increasingly common. In fact, they are transforming orthodontic care.

Clear aligners work discreetly to slowly align teeth that are misaligned – known as malocclusion. They have transformed the appearance of many people’s teeth.

However, some challenges do exist with clear aligners, and they are not always effective. There are some factors that can impact their effectiveness.

Now, new research has looked into creating an approach that ensures more predictable results and strong treatment outcomes.

Clear Aligners

The global market for clear aligners has been growing significantly in recent years. The global market size was an estimated $6.51 billion in 2024 [2].

Clear aligners are custom made to fit the exact measurements of a patient’s teeth. Then over time, aligners apply consistent pressure to guide teeth into their ideal location.

As mentioned, clear aligners aim to fix misaligned teeth. Misaligned teeth not only affect the appearance of a person’s teeth, but they also impact the functioning of teeth. This can cause difficulties in eating and swallowing in some cases.

The process of aligning takes time, but can produce very effective results. Unfortunately, not everyone will see an improvement in their appearance.

Because clear aligners rely on elastic forces to work, this can complicate complex corrections. Their effectiveness also requires a patient to follow instructions. Moreover, anatomical limitations can further impact their effectiveness [1].

The challenges mentioned above have, according to researchers, necessitated the need for a standardized approach towards clear aligners to ensure better results.

The Research

The research was carried out by a team from Sichuan University in China. Their findings have been published in the International Journal of Oral Science [1].

The researchers were aiming to create a standardized approach, which involved coming up with a consensus on best practices [1].

The researchers noted through their analysis that there are strengths and weaknesses to clear aligners. Predicting movements like molar distalization and expansion were praised as strengths [1].

However, the researchers noticed during their analysis that mechanical elements had some limitations. For example, these included torque control and extrusion [1].

The researchers developed a tool called CAT-CAT, with CAT standing for “clear aligner treatment” [1]. This tool grades cases into four levels of difficulty – easy, moderate, difficult, and challenging [1].

Therefore, this tool can be used by clinicians to plan treatment for their patients. Depending on the level of challenge that a patient’s teeth present, a different strategy can be followed [1].

For example, in complex – or ‘challenging’ – cases, the model recommends staged movements, mini-implants and overcorrection designs [1].

Furthermore, the researchers have emphasized the importance of making specific considerations for every patient. Adolescent growth potential and existing gum health should be monitored closely [1].

The researchers also suggest that 3D modelling should be used when possible, as this can enhance precision and personalize treatment to produce optimum results [1].

Overall, the researchers were pleased to reach a consensus. This consensus has the potential to have a large impact and should offer a framework for clinical aligner use worldwide [1].

The researchers believe that the CAT-CAT tool can help to tailor treatments, reduce trial and error approaches, and improve treatment outcomes [1]. Therefore, their work has numerous benefits for everyone involved.

Summary

The researchers hope that their analysis of different tooth movements and solutions for common complications can result in improvements in patient outcomes.

Professor Wenli Lai was one of the authors of the study and has commented on the findings. Lai says that “our consensus provides a roadmap for clinicians to navigate complexities,” which can lead to “predictable and efficient outcomes” [3].

Continuing, Lai said that “by integrating advanced digital planning and patient-specific strategies, we can unlock the full potential of this transformative technology” [3].

The researchers hope that they can further refine and develop the CAT-CAT tool in the future. They have proposed utilizing artificial intelligence-driven planning as a future area of development [3].

This is a very positive development. A critical part of any clear aligner treatment is the patient’s experience. By producing a standardized approach, this should improve the results for patients.

New research has led to teeth being grown in a laboratory for the first time. This landmark moment could have a big impact on dentistry and potentially offer a new treatment for those with missing teeth. While further research is needed, this is a significant milestone in ongoing efforts to find a way to get teeth to repair and regenerate themselves.

Our teeth are one of the most important parts of our body. Unfortunately, for numerous reasons, teeth can fall out or be extracted. Currently, for those missing teeth options are limited.

However, this may soon change, as in an exciting announcement, scientists from the United Kingdom have announced that they have grown human teeth in a lab for the first time [1].

This is an incredible finding, which could have wide-ranging implications for the future of oral health. It could result in lab-grown teeth being able to replace natural human teeth.

Background

Adults typically have 32 teeth. Teeth have a wide variety of roles, as well as obviously helping us eat, they help us to talk and even breathe.

Unfortunately, it is rather common for adults to lose one or more teeth. This could be due to extensive tooth decay, advanced gum disease, or trauma.

In fact, research shows that in the United States, the average number of natural teeth left by the time someone makes it to the age of 64 is 23.4 [2]. Therefore, tooth loss affects a range of people.

Dental implants and dentures have offered solutions in the past. While they are effective, they can also be costly, which stops some people from accessing this treatment.

Therefore, having other alternatives is desirable. Scientists have been trying for a long time to grow teeth in a laboratory. Now, there appears to have been a development.

The Research

The research was carried out by King’s College London in the United Kingdom. Their findings were published in the ACS Macro Letters journal [1].

Scientists at King’s College London have been exploring the potential of lab-grown teeth for over a decade [1]. They were finally able to make a breakthrough recently.

Currently, when a tooth becomes decayed, a filling is used. However, fillings weaken tooth structure over time and rarely last forever [1]. Implants can be used when whole teeth are missing, but they do not restore natural tooth function either.

Therefore, the aim has always been to get teeth to repair and regenerate themselves naturally [1].

But finding the exact environment and conditions needed to grow teeth in a lab has proven challenging. This has now seemingly changed.

The researchers have been able to introduce a special type of material that enables cells to communicate between each other [1]. Therefore, this means that one cell can ‘tell’ another cell to start differentiating into a tooth cell [1].

Incredibly, this means that the environment of growing teeth is mimicked. Therefore, scientists can recreate the process of tooth development in a laboratory [1].

The new material releases the signals that the cells use to communicate with each other slowly over time, rather than all at once [1]. This has proven to be a key reason for the success of this research, as this replicates what happens naturally.

The material takes the form of a hydrogel. In this study, the researchers prepared the hydrogel by mixing gelatin precursors that had been modified either with tetrazine or norbornene moieties [1].

The researchers were able to conclude that lab-grown teeth made from a patient’s own cells could integrate seamlessly into the mouth and repair themselves like a natural tooth [1].

Summary

This advancement marks the outcome of considerable research. It is a very important update and has the potential to have a big impact on dentistry.

It effectively means that in the future, humans may be able to replace lost teeth with a natural tooth using their own cells. This would be very positive and help those with missing teeth.

Xuechen Zhang of the Faculty of Dentistry, Oral & Craniofacial Sciences of King’s College London, was the lead researcher. He commented on the findings [3].

Zhang said “lab-grown teeth would naturally regenerate, integrating into the jaw as real teeth. They would be stronger, longer lasting, and free from rejection risks, offering a more durable and biologically compatible solution than fillings or implants” [3].

The researchers pointed out that the next big challenge will be to work out how to get teeth from the laboratory to the mouth of patients [1]. But the good news is that the research suggests that teeth can integrate well into mouths.

Xuechen spoke about this challenge and said that the team “have different ideas to put the teeth inside the mouth,” which includes “transplanting the young tooth cells at the location of the missing tooth and let them grow inside [the] mouth” [3].

Furthermore, Xuechen said “alternatively, we could create the whole tooth in the lab before placing it in the patient’s mouth,” though he noted that “for both options, we need to start the very early tooth development process in the lab” [3].

While further research is needed, this is an exciting development and underlines the potential that research into regenerative dentistry can yield.

Thinking points…

1) This is a very exciting update and underlines the great work that scientists are producing. However, if you look after your teeth, hopefully you won’t need to worry about lab-grown teeth! A good way of aiding your oral health is to attend regular dental check-ups. At a check-up, a dentist can take a thorough look at your oral health, provide advice, and suggest treatment if necessary. We recommend that you book an appointment right away!

2) While we wait for further progress on lab-grown teeth, there is a useful and effective alternative available for missing teeth – dental implants. Dental implants are artificial teeth that look and act like a real tooth. They look natural, are easy to fit, and tend to last many years. Here at Savanna Dental, we offer a free dental implant consultation for our patients. To find out more and to book an appointment, please see our website – https://savannadentalclinic.ca/!

The Alberta Dental Association has called for an Alberta-only provincial dental program to be launched. They believe that the current system of the Canadian Dental Care Plan and the existing provincial program have major shortcomings. They have put forward a few reasons why they believe a new system would be effective and improve the oral health of Albertans.

The ongoing rollout of the Canadian Dental Care Plan (CDCP) has put a spotlight on oral health in Canada.

The CDCP has helped many people, and in some cases, has worked well alongside and complimented existing federal and provincial dental programs.

However, the President of the Alberta Dental Association (ADA) has recently suggested that both the CDCP and existing programs have major shortcomings [1].

Therefore, the ADA have argued that these shortcomings need to be addressed. In fact, the ADA is calling for a made-in Alberta provincial dental plan [1].

They have put forward a few reasons why they believe this would be effective, and how it addresses the problems they have identified [1].

Calls for made-in Alberta Plan

As mentioned, the ADA have suggested that there are shortcomings in the CDCP. This opinion has been put forward by their President – Dr. Hans Herchen [1].

Therefore, Herchen has called for a made-in Alberta provincial dental plan. The ADA suggest that this plan would build on the strengths of the existing provincial dental program, addresses its gaps, and integrates funding from the CDCP [1].

Herchen has said that the ADA wish “to draw attention to the fact that both federal and provincial dental programs have a lot of administrative challenges,” and that there is a need to “resolve that red tape” [1].

Continuing, Herchen says that “we can provide better care on budget for patients in Alberta” [1]. The ADA have put forward several reasons to explain why they are advocating for a new, Alberta-specific, dental plan.

The CDCP undermines employer-based insurance

The first reason put forward by the ADA revolves around a perceived interference from the CDCP on employer-based insurance [1].

Currently, many Canadians receive dental insurance through their employer. However, a third of people living in Canada did not have insurance as of 2023 [2].

Therefore, existing federal and provincial programs aim to help those without coverage. But the ADA have suggested this model may not be sustainable.

There have been long-term concerns from many that the CDCP could result in employers stopping dental benefits. This could have a negative long-term impact.

Herchen has said that “the biggest risk factor with [the] CDCP is the damage to the existing dental insurance plans, the employer-based plans” [1].

Continuing, Herchen says that the ADA are “very concerned that the well-served population will be losing their excellent dental plans, replaced with a less sufficient provincial or federal plan” [1].

Potential to improve the existing Alberta provincial dental plan

The ADA have pointed out that there are some strengths of the existing Alberta provincial dental plan [1]. If these strengths are leveraged, it could negate the need for the CDCP.

However, Herchen does say that provincial dental plans need to be “modernized,” due to being outdated and limiting [1].

Herchen mentioned that there are “a large number of Alberta dental patients that are currently underserved by provincial dental plans” [1].

This problem has been impacted too by the problem of struggling to recruit dental hygienists and assistants in Alberta.

Herchen believes that a better-structured provincial dental plan could attract more dental workers [1]. This would provide more choice and supply for patients.

Potential benefits of opting out of the CDCP

Alberta Premier Danielle Smith has previously announced that the province will be opting out of the CDCP from 2026 [3].

The ADA have also supported opting out of the CDCP. The belief is that this will enable Alberta to have a more effective and efficient provincial program [1].

This would mean that Alberta residents would no longer have access to the CDCP. But such a system would enable the Alberta government to receive the same federal funding that had been allocated to the CDCP [1].

Moreover, Herchen has suggested that this would offer “better coverage for Albertans,” whilst also lowering costs for taxpayers [1].

Tailoring solutions to Alberta’s demographics

As with any large country, different towns and cities will inevitably have different demographics. Alberta’s demographics are unique in Canada.

Herchen points out that Alberta “has a very large young population” [1]. This burgeoning population has driven a higher demand for dental services.

However, Herchen noted that the CDCP targets the older demographic. Therefore, he has suggested that the CDCP isn’t relevant for many people in Alberta.

This means that an Alberta-only plan could better tailor services to Alberta’s specific demographics. For example, services could be based more on those in demand by the younger population of Alberta.

Funding concerns

Finally, there are some funding concerns with the CDCP, which threatens its long-term sustainability. This is impacted by political, economic, and social factors.

Federal elections are already scheduled, with concerns around what will happen if the Conservative Party secure power. It has been speculated that funding for the CDCP could be stopped.

Indeed, Herchen says that “there is a lot of politics” involved [1]. Furthermore, he has pointed out that the CDCP’s fee increase for 2025 has not kept up with inflation.

Herchen also said that “most people’s experience with government programs is that they become increasingly restrictive over time” [1]. Clearly, Herchen has a range of concerns about the long-term feasibility of the CDCP.

Summary

These various reasons underline the ADA’s rationale for wanting an Alberta-only dental plan to exist. It could have a positive impact on the oral health of Albertans.

The different areas outlined look to safeguard the future of dental programs in Alberta and aid the overall health of the residents.

It will be interesting to see how oral health progresses in Canada over the next 12 months, with this likely to have consequences for every province.
