The LightForce Orthodontic System is a treatment planning software and orthodontic appliance system used to correct malocclusions in orthodontic patients using patient-matched orthodontic appliances.
Device Description
The LightForce Orthodontic System (LFO System) is a treatment planning software (TPS) and orthodontic appliance system used to correct malocclusions in orthodontic patients using patient-matched orthodontic appliances. The orthodontist uses the TPS (K200148) to select and order the patient-specific orthodontic brackets. The TPS allows the orthodontist to diagnose the patient, plan treatment, and position the orthodontic brackets based on a digital impression of the patient - the outcome of the TPS is a prescription for the patient-specific orthodontic brackets. The LFO System consists of patient-specific ceramic brackets, patient-specific bracket placement jigs, arch wire templates, and a TPS for viewing, measuring, and modifying cases. LightForce Orthodontics' (LFO) operators and the orthodontists use the TPS to generate a prescription of their choosing. LFO then manufactures the patient-specific brackets and placement jigs using proprietary additive manufacturing techniques. The orthodontist then bonds the brackets to the teeth using the optional placement jig and ligates wires to enable tooth movement. The LFO System does not contain commercially-available or patient-specific shaped arch wires, ligatures, or adhesives that affixes the brackets to the teeth.
More Information

No
The summary explicitly states "Mentions AI, DNN, or ML: Not Found" and the description focuses on software for treatment planning and manufacturing patient-specific brackets based on orthodontist input.

Yes.
The device is used to correct "malocclusions in orthodontic patients," which indicates a therapeutic purpose of treating an abnormal dental condition.

No

The device is described as a "treatment planning software and orthodontic appliance system." While the orthodonist uses the TPS to "diagnose the patient, plan treatment, and position the orthodontic brackets," the primary function of the system is treatment planning and correction of malocclusions, not diagnosis itself. The outcome is a prescription for orthodontic brackets, not a diagnostic finding.

No

The device is described as a "treatment planning software and orthodontic appliance system" and explicitly includes "patient-specific ceramic brackets, patient-specific bracket placement jigs, arch wire templates" as components of the system, in addition to the software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. They are used outside of the body.
  • LightForce Orthodontic System Function: The LightForce Orthodontic System is used to correct malocclusions in orthodontic patients. It involves treatment planning software and patient-matched orthodontic appliances (brackets). These devices are applied to the patient's teeth to physically move them.
  • Lack of Sample Testing: The description does not mention any testing of samples taken from the patient's body. The input is a "digital impression of the patient," which is a representation of the teeth, not a biological sample.

Therefore, based on the provided information, the LightForce Orthodontic System is a therapeutic device used for orthodontic treatment, not an in vitro diagnostic device.

Summary of Performance Studies

Bench testing was performed to ensure that the patient-specific brackets were similar to the LFO System predicate, Signature Orthodontic System. Performance testing consisted of shear bond strength and torque strength. Tensile testing, wire friction testing and bracket strength (fracture) testing were also completed as comparison tests.

  • Shear bond strength is the load per unit area required to remove a bonded bracket from a tooth when a shear force is applied in the occlusal-gingival direction. The shear bond strength of LFO System brackets is equivalent to or better than the predicate device.
  • Torque strength is the torque exerted on the bracket at fracture, when subjected to arch wire torsion. The torque strength of LFO System brackets is equivalent to or better than the predicate device.
  • Friction (wire draq) force is the force required to drag a ligated stainless-steel wire through the primary slot of the bracket. The friction (wire drag) force of the LFO System brackets is equivalent to the predicate device.
  • Tensile bond strength is the load per unit area required to remove a bonded bracket from a tooth when a tensile force is applied to a stainless-steel wire ligated to the primary slot of the bracket. The tensile bond strength of LFO System brackets is equivalent to the predicate device.
  • Tie-wing tensile fracture strength is the fracture strength of the tie-wing complex when a tensile load is placed directly under the tie wing. The tie wing tensile fracture strength of LFO System brackets is equivalent to the predicate device.

Device Description

The LightForce Orthodontic System (LFO System) is a treatment planning software (TPS) and orthodontic appliance system used to correct malocclusions in orthodontic patients using patient-matched orthodontic appliances. The orthodontist uses the TPS (K200148) to select and order the patient-specific orthodontic brackets. The TPS allows the orthodontist to diagnose the patient, plan treatment, and position the orthodontic brackets based on a digital impression of the patient - the outcome of the TPS is a prescription for the patient-specific orthodontic brackets. The LFO System consists of patient-specific ceramic brackets, patient-specific bracket placement jigs, arch wire templates, and a TPS for viewing, measuring, and modifying cases. LightForce Orthodontics' (LFO) operators and the orthodontists use the TPS to generate a prescription of their choosing. LFO then manufactures the patient-specific brackets and placement jigs using proprietary additive manufacturing techniques. The orthodontist then bonds the brackets to the teeth using the optional placement jig and ligates wires to enable tooth movement. The LFO System does not contain commercially-available or patient-specific shaped arch wires, ligatures, or adhesives that affixes the brackets to the teeth.

Intended Use / Indications for Use

The indications for use are the same between this submission and the primary predicate K181271.

The LightForce Orthodontic System is a treatment planning software and orthodontic appliance system used to correct malocclusions in orthodontic patient-matched orthodontic appliances.

The LightForce Orthodontic System in the primary predicate (K181271) is a treatment planning software and orthodontic appliance system used to correct malocclusions in orthodontic patients using patient-matched orthodontic appliances. This current submission provides hardware updates to the hardware delivered in the primary predicate.

Technological Characteristics

LightForce Orthodontic System is similar to other legally marketed devices - while the patient-specific ceramic brackets are equivalent to the Signature Orthdontic Brackets of K181271. Table 6-1 provides a comparison of the LFO System to the predicate devices.

The LFO System patient-specific brackets, like its predicate Signature Orthodontic, are composed of a polycrystalline alumina with a twin bracket design consisting of tie-wings for ligation, a primary arch wire slot and auxiliary slots. There are rounded corners and edges along with a rounded hook on the distal-gingival tie wing of canine brackets to accommodate accessories during orthodontic treatment. These design features allow a ligature wire, in tension, to move the bonded brackets along a designated path until the desired tooth position is

5

achieved. The brackets are non-self-ligating with a mechanical locking base design and built through additive manufacturing methods.

Non-clinical Performance Testing

Bench testing was performed to ensure that the patient-specific brackets were similar to the LFO System predicate, Signature Orthodontic System. Performance testing consisted of shear bond strength and torque strength. Tensile testing, wire friction testing and bracket strength (fracture) testing were also completed as comparison tests.

    1. Shear bond strength is the load per unit area required to remove a bonded bracket from a tooth when a shear force is applied in the occlusal-gingival direction. The shear bond strength of LFO System brackets is equivalent to or better than the predicate device.
    1. Torque strength is the torque exerted on the bracket at fracture, when subjected to arch wire torsion. The torque strength of LFO System brackets is equivalent to or better than the predicate device.
    1. Friction (wire draq) force is the force required to drag a ligated stainless-steel wire through the primary slot of the bracket. The friction (wire drag) force of the LFO System brackets is equivalent to the predicate device.
    1. Tensile bond strength is the load per unit area required to remove a bonded bracket from a tooth when a tensile force is applied to a stainless-steel wire ligated to the primary slot of the bracket. The tensile bond strength of LFO System brackets is equivalent to the predicate device.
    1. Tie-wing tensile fracture strength is the fracture strength of the tie-wing complex when a tensile load is placed directly under the tie wing. The tie wing tensile fracture strength of LFO System brackets is equivalent to the predicate device.

Clinical Performance Testing

No clinical performance testing was conducted on LFO System brackets.

Substantial Equivalence

The LightForce Orthodontic System (LFO System) is the same as the predicate device; Signature Orthodontic Brackets. The LFO System has the same intended uses/indication for uses, technological characteristics, and principles of operation as its predicate devices. The performance data provided above demonstrates that the LFO System performs at an equivalent

8

or better level compared to Signature Orthodontic Brackets. The minor technological differences between the LFO System and the predicate device, Signature Orthodontic brackets, raise no new issues. There are no alterations in the intended use or the underlying technology or science involved. Thus, the LightForce Orthodontic System is the same as its predicates.

Conclusion

Additionally, the LFO System has the same intended use, composition, design, function, physical properties and performance as its predicate devices. As shown in our performance data, the difference in manufacturing method does not impact the device's intended use and performance. The results from the nonclinical performance testing and the biocompatibility assessment demonstrate that LFO System brackets, along with the appropriate arch wires, constitute standard orthodontic appliances which are equivalent to existing appliances used in the clinical environment.
