Fewer Attachments

Why can Promonitoring use fewer or no attachments compared to competitors?

Answer: our aligners are designed to minimize or even eliminate the need for attachments, which offers several advantages over competitors. Here’s a detailed explanation:

1. Historical Context:
   • Early Aligners: Initially, aligner therapy didn't use attachments.
   • Introduction of Attachments: Over time, the use of attachments became prevalent, but they were often disliked by both patients and practitioners due to discomfort and inconvenience.
2. Disadvantages of Attachments:
   • Patient Discomfort: Attachments can make aligners uncomfortable when removed for eating.
   • Inconvenience: Both dental staff and patients generally find attachments cumbersome and undesirable.
3. Straight Trim Design:
   • More Tooth Surface Area: The straight trim design does not scallop around the teeth but stays about 1-1.5 millimeters above the gingival margins.
   • Embrasure Surface Utilization: This design takes advantage of the embrasure surfaces of the teeth, acting like natural attachments and improving tooth movement without additional attachments.
   • Better Contact: Unlike scalloped trims that can lose contact with the tooth over time, the straight trim ensures consistent contact.
4. Supporting Research:
   • 2012 Study on Trim Design: A study compared different trim designs and found that a straight margin cut at 2 millimeters above the gingival margin was the most effective in retaining the aligner. This design provides better retention and contact, which improves tooth movement efficiency.
5. Fabrication Accuracy:
   • High Precision: Our aligners are fabricated with up to 96 microns of accuracy against 3D printed models, which is over 50% more accurate than many competitors.
   • Better Retention: Higher fabrication accuracy leads to better aligner retention and adherence to the tooth, enhancing the effectiveness of tooth movements without the need for additional attachments.

By utilizing a straight-trim design and ensuring high fabrication accuracy, our aligners can achieve effective tooth movements with fewer or no attachments, offering a more comfortable and convenient experience for patients and practitioners alike.
