Invisian Medical at National Conferences

Invisian Medical was pleased to support three national conferences this fall: the 2021 AAOMS Annual Meeting, the AAO-HNSF 2021 Annual Meeting, and the 2021 ASTMJS Fall Meeting.

Thank you to everyone who was able to visit our booth and learn more about Minne Ties; we hope to see you again next year! Invisian Medical was also pleased to sponsor the Resident Reception this year at AAOMS (right photo). It was great to connect with so many of you to learn from you and share important information and updates. Click here to view more photos from these conferences.


Patient Case Report

Minne Ties are being used in a wide variety of ways: for trauma, orthognathic cases, especially with Invisalign, and in TMJ total replacement cases. Recently Minne Ties have been used more frequently for closed treatment of mandible fractures (in addition to ORIF). The following patient case report highlights use in closed treatment.

Closed Treatment of a Unilateral Mandible Fracture Using Minne Ties Agile MMF

Briana Burris, DDS (Massachusetts General Hospital)

A 34-year-old male with excellent premorbid occlusion presented to the Massachusetts General Hospital Emergency Department with facial swelling and lower jaw pain, after sustaining a sports injury. After assessing the patient and performing a CT scan, the ED consulted OMFS regarding the management of the patient’s right parasymphysis fracture. The patient initially requested open treatment to avoid maxillomandibular fixation (MMF), given his significant dental anxiety. The patient was presented Minne Ties Agile MMF as an option and subsequently consented to closed treatment. One medium and two large Minne Ties were applied on each side of the patient mouth in the clinic under local anesthetic. The total procedure time was approximately 20 minutes.

After a short course of MMF, the Minne Ties were removed in clinic without administration of sedation or local anesthetic. The patient tolerated Minne Ties well and endorsed premorbid occlusion at the time of removal. Dr. Burris said, "Minne Ties Agile MMF are impressive in their ability to achieve both patient-satisfaction and provider satisfaction as a minimally cumbersome, sufficiently strong, and efficient option for closed reduction MMF. This case highlights Minne Ties’ utility in patients with significant anxiety, situations where sedation may not be possible, and decreased chairside time compared to conventional options like Erich arch bars. Given the positive outcome, this case represents the first of what will eventually become broader utilization of Minne Ties for appropriate patients in the clinic, ED and OR at Massachusetts General Hospital."

Assessment of Dentition for Minne Ties Placement

Minne Ties are most frequently used to achieve maxillomandibular fixation on patients with good dentition and relatively tight contacts. Based on surgeon feedback, the most common application consists of 3-4 Minne Ties per side, which provides the strongest, most stable and durable construct. The largest size Tie (1.0mm/18g) is used most frequently due to its strength and lower chance of “flossing out” between the teeth. However, patients with especially tight embrasures may require the use of the medium size Minne Ties (21g/0.7mm). Use of the medium size generally requires tight contacts to prevent flossing out; therefore, using the large size whenever possible is recommended. With experience, alternative application techniques can be used successfully when patients have less than ideal dentition (e.g. gaps between teeth, missing some dentition, misalignment of maxillary and mandibular embrasures, etc.).
