“…However, a recent prospective comparative study has concluded similar skeletal and dentoalveolar effects of both pendulum appliance and K-loop. [8] In another study, the authors have found the use of a pendulum appliance supported buccally by K-loop, overcame the disadvantages of intraoral appliances, namely distal molar tipping and loss of anchorage. [1] In the present study, a combination of two intraoral appliances (pendulum and K-loop) was used and results were compared to pendulum only appliance.…”

Most non-extraction Class II malocclusions are treated by extraoral and intraoral appliances for molar distalization. Extraoral traction is effective but depends on patient cooperation. This led to the use of intraoral appliances; however, they too have drawbacks such as molar tipping and loss of anchorage. In this case report, a 13-year-old patient with Class II malocclusion with good facial balance is treated non-extraction. The two quadrants were divided into pendulum only and pendulum K-loop combination to compare the amount of molar tipping and dentoalveolar changes on both sides. The left upper quadrant has Hilgers pendulum appliance (pendulum only). On the right side, pendulum was adjuncted buccally by Karla's K-loop appliance using split-mouth technique. It was concluded that Class I molar and canine relation was achieved faster on pendulum only side, though it presented with more distal molar tipping as compared to pendulum K-loop combination side which showed a controlled molar distalization.

Introduction: The study was conducted to assess the stress and displacement effects of a mini-implant supported k-loop on the maxillary dentition for distalization with 3-dimensional (3D) finite element stress analysis. Materials and Methods: A 3D model of the maxilla with all teeth, periodontal ligament, bone, mini-implants, brackets, and archwire was used in this study. The analytic model used in this study like brackets, wire, K-loop, and mini-implants was developed using a reverse engineering technique extracting the dimensional details of the physical parts using precision measuring instruments. Results: The distobuccal movement on the first molar and second molar were 0.26864 mm and 0.00833 mm, respectively. A total of 0.25 mm intrusion movement was seen on distal cusp of the first molar and 0.14 mm extrusion movement seen on mesial cusp of the first molar. A total of 0.25 mm and 0.00260 mm intrusion movement was seen on the distal cusp of the first molar and second molar, respectively. A total of 0.14 mm and 0.00324 mm extrusion movement was seen on the mesial cusp of the first molar and second molar, respectively. Conclusions: There was a large amount of distal displacement of the first molar, also negligible amount of tipping of the first molar and mesial movement of first premolar.

Extraction therapies are commonly done in patients with protrusion and/or crowding which demands a thorough understanding of biomechanics. Two basic types of space closing mechanics are friction/sliding and frictionless/loop mechanics. In the former, the wire and position of the bracket are important factors in tooth movement but the simplicity of friction mechanics is offset by the binding between bracket and archwire and may be associated with undesirable side effects such as uncontrolled tipping and deep bite. In frictionless mechanics, specially designed springs are used which provides the required moment to force ratio (M/F ratio) in three dimensions and they are more predictable and versatile. An electronic literature search was conducted via google scholar, PubMed, and dental associations’ of different countries’ website using the key word “Loops” and “Frictionless mechanics.Different configuration of loops have been used in orthodontic treatment and a comprehensive review of types of loops commonly used in retraction has been highlighted in this article.: Provide appropriate messages of about 35-50 words to be printed in centre box:In frictionless mechanics, specially designed springs are used which provides the required moment to force ratio in three dimensions and they are more predictable and versatile.
