Indications for Use
The OrthoPulse™ device is intended for use during orthodontic treatment. It is used in conjunction with brackets and wires or aligners and helps facilitate minor anterior tooth movement.
Device Story
OrthoPulse is an intra-oral, mouth-guard-style appliance used by patients at home during orthodontic treatment. It delivers 850nm near-infrared light energy to the alveolar surface via LEDs embedded on a flexible circuit. The device treats one arch at a time and is reversible for the other arch. Operation is controlled by internal software, which manages the 5-minute daily treatment session duration and frequency. The device includes an integrated rechargeable battery and a wireless charging/storage case. It features an optional wireless connection to an iOS application for patient compliance monitoring. By delivering light energy, the device aims to accelerate the rate of tooth movement, potentially reducing overall orthodontic treatment time. Healthcare providers prescribe the device, and patients self-administer the treatment.
Clinical Evidence
Two primary clinical studies supported efficacy. A cross-over study (n=21) evaluating OrthoPulse with aligners showed statistically significant faster tooth movement compared to baseline (p=0.024). A controlled study (n=33) evaluating OrthoPulse with brackets and wires showed statistically significant faster tooth movement compared to matched controls (p<0.001). No serious adverse events, root resorption, or pathological tooth mobility were reported. Additional prototype studies confirmed performance.

### Intended Use / Indications for Use
The OrthoPulse™ device is intended for use during orthodontic treatment. It is used in conjunction with brackets and wires or aligners and helps facilitate minor anterior tooth movement.
### Device Description
The OrthoPulse'''' device is an intra-oral appliance similar to a plastic sports mouth guard that is intended for use during orthodontic treatment in conjunction with traditional orthodontic treatment with brackets and wires or aligners.
The device achieves its effect by delivering light energy to the bone, accelerating the rate of tooth movement. Light-emitting diodes ("LEDs") are embedded into the mouth-guard on a flexible circuit. Light is directed toward the alveolar surface to facilitate light treatment of the anterior arch segment during orthodontic tooth movement. The intra-oral appliance is designed to treat one arch (upper or lower), and is reversible by the patient to treat the other arch.
OrthoPulse is considered a low level light treatment device and produces light at levels 50-80 mW/cm for the patient. The device is designed to comply with the lamp safety standard (IEC 62471: 2006) and with the general medical device standard IEC 60601-1 3rd Ed.
OrthoPulse includes light with wavelengths in the 850nm range (near infrared) and the treatment protocol is based on a daily treatment session of 5 minutes per arch (maxilla or mandible). The treatment time (session duration) is controlled by the software, along with the number of treatments per day.
OrthoPulse includes an integrated battery for power. The battery is rechargeable via a wireless charging platform / storage case. The device provides a wireless connection to an optional iOS application to enable monitoring of patient compliance with the treatment regimen. No other cable or connection to external devices is required.
#### Technological Characteristics
OrthoPulse™ has very similar technological characteristics as the predicate device. Both devices are intraoral appliances intended for home use under a prescription, and both devices are comprised of portable, battery powered devices that are placed in the user's mouth at regular intervals. Although OrthoPulse uses light energy to accelerate tooth movement while the predicate uses mechanical vibration, both devices are designed to achieve the same therapeutic effect of achieving faster tooth movement. The devices are both comprised of equivalent components, including the mouthpiece, battery component, and software. The differences in technological characteristics compared to the predicate do not adversely impact performance, as demonstrated in bench and clinical testing. Therefore, OrthoPulse presents similar technological characteristics as it predicate device, in support of substantial equivalence.
{5}------------------------------------------------
## Performance Data
The following tests have been performed to support the substantial equivalence of OrthoPulse™:
- . Optical Output Testing
- . Lifetime Verification Testing
- Testing to ensure that the device can withstand bite forces in the mouth
- Testing to ensure the device can accurately detect when it is in contact with tissue
- . Biocompatibility testing in accordance with ISO 10993-1, ISO 10993-5, ISO 10993-10
- . Electrical safety testing in accordance with IEC 60601-1
- . Electromagnetic compatibility testing per IEC 60601-1-2 (3rd ed., 2007 and CISPR 11:2010)
- . Testing to validate the cleaning instructions
- Software verification and validation .
Further, clinical testing of the device with orthodontic treatment demonstrated that the device may accelerate tooth movement and may decrease treatment time. Two primary clinical studies of the intra-oral OrthoPulse demonstrated device performance for its indicating that the device may accelerate orthodontic movement of teeth and may reduce the overall treatment time for the patient when used in conjunction with traditional orthodontic treatment with brackets and wires or aligners. In a cross-over study where subjects served as their own control, 21 subjects (mean age 34.9 years) who used OrthoPulse with aligners was evaluated. Eligibility criteria included requiring that the subjects have permanent dentition, mild to moderate crowding with no labiolingually displaced teeth, Class I or Class II by ½ cusp or less, good oral hygiene, and non-smoking. Subjects who were pregnant, enrolled in another study, had periodontally involved teeth, used bisphosphonates during the study, or had spaces between anterior teeth were excluded. Perimeter measurement analysis was used to evaluate each patient's rate of tooth movement during baseline and OrthoPulse™ periods in the mandibular arch. The degree of external apical root resorption was also investigated. Study subjects were followed from the start of aligner orthodontic treatment until 6 months. Results demonstrated statistically significantly faster tooth movement compared to baseline (p=0.024), achieving the primary effectiveness objective of the study. There were no serious adverse events, and no root resorption, gingival recession, or pathological tooth mobility was reported throughout the study.
OrthoPulse was also evaluated in conjunction with brackets and wires in a controlled study of 33 subjects (mean age 25.0 years). Matched controls (based on subjects' age, initial crowding, eligibility criteria) were retrospectively selected before any data analysis of the OrthoPulse subjects. Eligibility criteria included requiring that the subjects have permanent dentition, moderate to severe crowding (LII ≥ 3 mm) with no labiolingually displaced teeth, Class I or Class II by ½ cusp or less, non-extraction in both arches, good oral hygiene, and non-smoking. Subjects who were pregnant, enrolled in another study, had periodontally involved teeth, used bisphosphonates during the study, or had spaces between anterior teeth were excluded. There were no differences between groups in terms of gender, ethnicity, age, and initial crowding. The rate of tooth movement was measured using the change in Little's Irregularity Index measurements in both groups to evaluate OrthoPulse™ use with fixed orthodontic appliances. Root resorption was determined by use of panoramic dental X-rays collected before treatment and after 6 months of treatment. Results demonstrated that subjects treated with OrthoPulse
{6}------------------------------------------------
showed a statistically significantly faster rate of tooth movement (p<0.001) compared to the control group, achieving the primary effectiveness objective of the study. There were no serious adverse events, and no gingival recession or pathological tooth mobility was reported throughout the study. Data demonstrated the absence of external apical root resorption with OrthoPulse use, and that there is no device effect of accelerated tooth movement on tooth root integrity. Therefore, results from the primary clinical studies demonstrate that subjects treated with OrthoPulse achieve statistically significantly faster rates of tooth movement than control.
Several additional clinical studies were also conducted with prototype and final OrthoPulse devices to supplement the clinical findings observed in the primary studies, and results consistently confirmed device performance for its indicated use.
# Substantial Equivalence
OrthoPulse™ has the same intended use and indications for use as the predicate device. As described above, the technological characteristics are also very similar between the two devices; both devices are intended for home use under a prescription, and both devices are comprised of portable, battery powered devices that are placed in the user's mouth at regular intervals. Although OrthoPulse uses light energy to accelerate tooth movement while the predicate uses mechanical vibration, both devices are designed to achieve the same therapeutic effect of achieving faster tooth movement. Bench and clinical testing demonstrates that the difference in technological characteristics compared to the predicate does not adversely impact performance, and does not raise different questions of safety and effectiveness compared to the predicate device. Thus, OrthoPulse is substantially equivalent.
