“…Fields, Cardenas and Wolford [16] studied the pull-out strength of Mitek mini-anchors inserted in 20 human cadaver condyles, demonstrating an average pull-out load of 16.0 lb (range 8.5-28.4 lb). The pull-out strength of the orthodontic mini-implants range between 17.8 and 66.3 lb [17], and this strength appeared to be more than adequate to stabilize the disc to the anchor along with condylar movement.…”

Introduction Various surgical modalities have been tried for the correction of chronic recurrent dislocation of the temporomandibular joint. However, most of these techniques are aimed at creating an artificial block or removing any interference in the path of the translating condyle. Chronic dislocation can also be classified as meniscotemporal and menisocondylar, depending upon whether the dislocation occurs between the condyle-disc unit and temporal bone (meniscotemporal), or between the disc and condyle (meniscocondylar). Very few procedures address the primary issue of a malpositioned disc, which is the cause of meniscocondylar dislocation. Materials and Methods This study was conducted on 17 patients (27 joints) who reported with chronic dislocation of the temporomandibular joint, with MRI-proven meniscocondylar dislocation. After exposure of the condyle and disc through a standard pre-auricular incision, an orthodontic mini-screw was fixed to the posterior aspect of the condylar head and a 1-0 Prolene suture passed through the screw-head eyelet, plicating the posterior edge of the disc to the condyle. This ensured that the condyle and disc would move in unison.Results All the patients showed improvement in their symptoms of dislocation in the postoperative period, including seven patients in whom only a unilateral procedure was carried out. None of the patients had any recurrence till the 1-year followup. Conclusion Our procedure addresses the fundamental etiology of meniscocondylar dislocation by anchoring the disc to the condyle by using an orthodontic mini-implant and correcting the condyle-disc disharmony. This technique is reliable, technically feasible, and cost-effective in the Indian set up.

Purpose:The aim of this study is to evaluate outcome of Mitek mini anchors (DePuy Mitek, Raynham, MA) in TMJ discopexy and assess patient satisfaction based on MRI findings.Patients and Methods:7 patients suffered from significant pain and dysfunction diagnosed on MRI findings as anterior disc displacement without reduction selected for this study. Anchor stability, assessment of positional changes and roofing were evaluated by postop MRI and OPTGs. Satisfaction was assessed with VAS. Preop and postop maximum interincisal opening measurements were compared.Results:There was significant difference between preop and posto P values of MIO and VAS. All 7 patients noted complete absence of pain at the postop 1-year follow-up. Only 1 patient had postop clicking but showed remarkable improvement of jaw functions (MIO). The articular disk was observed at its normal position in 6 patients except one patient whom MRI confirmed postop partial roofing. OPTGs reveal neither radiologic changes around the mini anchors in the condylar head nor any positional shifts.Conclusion:Disc repositioning with Mitek mini anchors represent improvement in post-op VAS scores and clinical findings (MIO) based on comparison preop and postop MRI scans and panoramic films. However, our study group consists of limited number of patients, further studies with more number of cases are required to evaluate the outcomes

“…Fields, Cardenas, and Wolford evaluated the pullout strength of 20 Mitek mini anchors placed in human cadaver condyles (24). Pullout thresholds were reached when the cortical bone overlying the anchor gave way (18 condyles) or when the suture broke (2 condyles).…”
