Multiloop edgewise archwire technique and denture frame analysis: a systematic review

Abstract

Background The Multiloop Edgewise Archwire (MEAW) appliance is an orthodontic treatment method suitable for the therapy of severe types of malocclusions such as open bites or anterior crossbites. The cephalometric Denture Frame Analysis (DFA) provides a supportive diagnostic tool for patient-specific treatment planning concerning the rearrangement of occlusion within the “denture frame”. The objective of this study is to give a comprehensive overview of the national and international scientific literature about MEAW and DFA regarding the general therapeutic effects, advantages and limitations. Methods and materials A computerized literature search was performed using four principal medical databases (PubMed/Medline, Google Scholar, Web of Science and Cochrane Central Register of Controlled Trials) and supplemented by manual searching of the references listed in the retrieved articles. The results were screened and assessed following the PRISMA guidelines. Results Six hundred seventy-seven full articles were assessed for eligibility. A number of 134 articles went through qualitative analysis and 3 studies were finally involved in comparative synopsis. The findings reveal advantageous characteristics of the MEAW technique such as a high degree of three-dimensional individual tooth control and a comparatively low load deflection rate, causing mostly dentoalveolar changes without significantly influencing the skeletal structures. Conclusion Based on current literature, the MEAW technique appears to have several therapeutic benefits and serves as a sufficient alternative treatment method for dentoalveolar compensation, when measures of orthognathic surgery are rejected. Concerning the deficient data basis of available literature and the low level of scientific evidence, further studies are required in order to expand on the knowledge in this subject area. Several aspects like the effectiveness or the long-term stability have to be evaluated more extensively. Moreover, the transferability of the DFA to ethnic groups other than the Asian ethnicity should be examined further.

Intrusion of the maxillary posterior teeth with a single buccal mini-implant positioned bilaterally in young adults with a tendency towards hyperdivergence: A clinical study

“…Various methods have been reported in the literature to achieve intrusion. Molar intrusion in the maxillary arch may be performed with bone plates (Erverdi et al, 2004; Sherwood et al, 2002), infrazygomatic implants (Almeida et al, 2019; Flieger et al, 2012), palatal mini-implants (Wilmes et al, 2020) or a combination of buccal and palatal mini-implants (Paccini et al, 2016; Yao et al, 2005) and other conventional methods (He et al, 2013; Tabancis et al, 2020). We chose a single buccal mini-implant per side in the current study to keep the number of mini-implants to a minimum and still consider the possibility of intrusion of the maxillary molars.…”

Multi-Loop Edge Wise Arch Wire Technique (MEAW) – A Review

“…Therefore, the angle measurement should be understood as a figure representing the correlation of skeletal adaptation in occlusal function. 18 Two greatest factors which decreases ODI A. l. High angle open bite condition resulting from mandibular hyperdivergence 2. Class Ill condition resulting from the anterior adaptation of the mandible Either of these two factors may affect the vertical dimension of malocclusion.…”

“…It is important to consider these factors in establishing a treatment plan. 18 LIMITATIONS OF MEAW 1. While comparing the MEAW method with the straight wire technique some limiting factors occur.…”

Strategic treatment planning for anterior open bite: A comprehensive approach

“…Moreover, maintaining the molars in a distally upright position is advantageous to the whole arch distalization of dentition in non-extraction cases. However, evidence supporting the efficacy of the MEAW technique in modifying skeletal patterns 56 is lacking. Additionally, no consensus exists on whether the MEAW technique can be used in cases with molar intrusion.…”
