Use of Minne Ties® in Surgery First and Aligners Orthognathic Surgery
Indiana University, Indianapolis, IN, USA
Waldemar D. Polido, DDS, MS, PhD. Clinical Professor, OMFS
A surgery first approach for orthognathic surgery is indicated when the post-operative occlusion can be finalized with orthodontics, and the face and airway aspects can be improved by the surgeon (Alfaro et al, 2011). The use of aligners in orthognathic surgery has also increased significantly (Caminiti and Lou, 2019). Intra-operative IMF using Minne Ties can be easily and successfully obtained in those situations.
A 19 year old patient presented to the orthognathic clinic with chief complaint of “want to improve my bite.” She had previous orthodontic treatment at age 14-15. Upon clinical examination, she was diagnosed with mandibular deficiency and a class II malocclusion, which was confirmed with lateral cephalometric measurements. Models were printed, and final occlusion in a class I was defined with the orthodontist. Surgical treatment plan was to perform a mandibular advancement. A surgery-first approach was utilized, since we were able to obtain a stable post-operative occlusion and improve overall facial esthetics and airway. Orthodontic treatment post-surgery was decided to be performed with aligners, without the use of brackets.
When brackets are not available, intra-operative inter-maxillary fixation after the bilateral sagittal split can be obtained through interdental wires (Ivy loops), intermaxillary (IMF) screws, or the use of Minne Ties. Ivy loops can cause more trauma to the gingival tissues and have a higher chance to loosen during fixation. IMF screws are stable but can lead to damage of adjacent teeth roots. The choice on this case was to utilize Minne Ties, to achieve a stable intraoperative IMF.
After SSRO were successfully completed, IMF was obtained using the splint, in the planned occlusion. Fixation of the proximal segments was obtained using three bicortical screws in each side. IMF was strong and stable during fixation. After removal of the IMF and splint, the occlusion was checked intra-operatively to confirm the planned position. A two-week follow-up shows the planned occlusion, and orthodontics ready to start with aligners.
The use of Minne-Ties brings advantages in comparison to other IMF methods, especially in cases of orthognathic surgery first and orthognathic cases with the use of aligners as orthodontic treatment.
Getting Reliable Results with Minne Ties
One small decision at the start of the application can make a meaningful difference in how your Minne Ties perform throughout the case. Selecting the appropriate embrasure space is critical to achieving a stable, reliable construct. For optimal stability, place 3-4 Minne Ties on both the left and right sides of the molars and premolars (6-8 total Ties) whenever the dentition allows. The stronger proximal contacts in these regions, compared with canines and incisors, provide a more secure hold and significantly reduce the risk of a Minne Tie slipping through the teeth (“flossing out”).
When patient anatomy or clinical circumstances limit placement in the molars or premolars, alternative application techniques should be used. Click the link below and scroll to the “Alternative Application Technique” section to learn more.
