Kika Ortodontia

Dear Orthodontist

Have you ever wondered why the world's largest luxury car manufacturers such as Lamborghini, BMW and Audi started using laser welding technology?

Very simple, for the rigidity provided to withstand the twists and impacts, the search for the lowest weight and comfort, thus we have safe, resilient and comfortable designs.

Now imagine offering your customers the LASER Welding Technology in a "simple" orthodontic appliance, able to absorb the forces exerted, with reduced weight, without the grotesque and toxic silver welds that oxidize with time, with comfort and aesthetics incomparable, in addition to the infinite possibilities of new. More than offering a therapy, you can offer the luxury and technology of Lamborghini to your patients, think about it!

Laser Welding in Laboratory Orthodontics

The LASER described by Albert Einstein in 1917 means 'Amplification of light through stimulated emission of radiation', which becomes interesting due to the production of a high quality beam of radiation, independent of its quantity, that next to Argon (Ar) of high purity, becomes indispensable to obtain maximum efficiency in the welds.

Its process is by the localized fusion of various metals, through the bombardment by light beam concentrated, coherent and monochromatic light of high intensity, having as an advantage over conventional methods, complete penetration, the quality of the joints and to be realized in autogenous form , frees us from the use of toxic materials such as silver solder.

Silver solder toxicity

The "World Health Organization International Agency for Research on Cancer" and "United States National Toxicology Program" have considered cadmium, copper, silver and zinc components of silver solder as metals with carcinogenic potential in humans and for the International Register of Potentially Toxic Chemical of the United Nations Environment Program, these components are considered to be potentially hazardous chemicals, and are included in the list of substances of great risk to human health.

And how does this happen on a daily basis?

The oral fluids cause corrosion in silver solder, releasing these ions with potential for toxicity to the body, different from the LASER solder that according to studies performed, is well tolerated by the cells, thus having high biocompatibility.

Silver soldering in orthodontics is a toxic material that inhibits the proliferation, growth and development of cells and that the release of zinc, copper, silver and cadmium ions physiologically and metabolically influence the oral cavity by the solder used in orthodontic appliances and in the corrosive process that is triggered.

Biomechanical Control and Excellence in Orthodontic Movement

Clinical Steps

For orthodontic success it is essential for the professional to establish the goals of orthodontic treatment, determining which movements are necessary to reach. The next step is to determine how to perform these movements.

Increasingly, we are looking for the most effective movement, with a lower biological cost and that provides the patient with the greatest comfort and the minimum need for cooperation. Today there are technological and scientific conditions so that we can individualize the treatment plan to the needs of our patient, respecting their biological needs, expectations and limitations.

Current Challenges

I believe that you, like me, have encountered cases where the need for complex force systems has become unfeasible because of the discomfort caused to your client.

Yes! Unfortunately, we often do not achieve optimal biomechanical control, as we find limitations between existing designs.

What Laser Welding Can Do For Your Patient

Imagine a world where we can model the device fully adjusted to the oral cavity. Combining comfort, ideal anchorage and a configuration that draws the line of action of force that best fits the desired movement! The introduction of laser welding in orthodontics brings a unique option to create a light and comfortable design, offering a range of thickness options and different metal alloys individualized to your patient with devices modeled to your biomechanical need and respecting the biological limits.

Welded appliances offer a reduced size, often without the use of acrylic resin, offering greater comfort and ease of sanitization.

The use of thicker yarns offers greater biomechanical control by avoiding undesirable deflections during movement, this significantly increases the control of the anchorage and the control of the line of action of the force to its point of application. The possibility of welding different metal alloys provides a configuration that builds a specific force system.

By joining lighter, more comfortable devices to the control of the anchorage and power lines, we invite you to enjoy this technology and bring together new devices and win big smile from your patients.

The Kika Orthodontics Laboratory is available to participate in research projects, together with educational institutions, offering orthodontic appliances with LASER technology.

In order for our commitment to improve the level of evidence of orthodontic procedures, we must carry out our studies with the greatest exemption, methodological quality and respect for regulatory institutions.

Our company, committed to offering the highest quality services, always seeks to support the scientific advances of orthodontics by offering our services for quality research. For this, we request the sending of the following items so that we can start the procedures to be performed by us:

  • Complete description of the scientific project containing all its methodology.
    • Note: In case there is disagreement or doubts regarding the methodology to be applied, we reserve the right to suggest a professional with expertise in the area of scientific methodology for its adequacy..
  • Copy of the authorization ethics committee registered in the Brazil platform.
  • Copy of the Terms of Free and Informed Consent signed by all study participants or their legal guardians.
  • Authorization to use files from the cases used in the study so that our company can include the data evaluated in other studies that evaluate the devices used in their research.
  • A formal commitment that results will be disseminated through scientific publication in scientific journals relevant to the subject matter or by making the data available for use in other original studies or scientific dissemination.

Build your device

If you have a device in mind, that before was unfeasible its production, send your idea, that we will develop your device, following your prescriptions.
