Unilateral scissor bite is a relatively rare malocclusion. However, its correction is often difficult and a challenge for clinician. This present "short clinical communication" indicates the versatility and use of micro-implants for the correction of severe unilateral scissor bite in an adult case.

| Introduction|| |
Unilateral scissor bite occurs in about 1.5% of the population and is difficult to treat orthodontically. , Conventional treatment mechanics do not offer a complete solution for the correction of severe transverse discrepancy, especially in adult patients.
| Diagnosis|| |
A 26-year-old male reported with the chief complaint of irregularly placed upper front teeth and difficulty in chewing from the right side of the mouth. The clinical examination revealed skeletal Class II base with orthognathic maxilla and retrognathic mandible, scissor bite on right side, severe crowding in mandibular anterior segment, increased overjet, and deep anterior overbite [Figure 1]a].

| Technique|| |
- A 0.022" × 0.028" MBT slot prescription was used. After leveling and alignment of upper arch, anterior bite plate with inclined plane was cemented which aided the disclusion of posterior teeth [Figure 1]b]
- Micro-implant (Dentos, 1312-08) was placed on the right side between the roots of mandibular second premolar and first molar [Figure 1]b]
- In the right posterior segment, a 0.019" × 0.025" stainless steel (SS) sectional wire was placed from first premolar till the second molar [Figure 1]b]
- SS buttons were bonded on mandibular first and second premolars and welded lingually on molar bands of first and second molars. Continuous ligation was done from mandibular first premolar to second molar. Anchorage was reinforced and posterior segment was made into a single unit [Figure 1]b]
- 0.010" ligature wire (3 times twisted together forming a thick section) was secured with composite resin on occlusal aspect of mandibular first and second premolars and first molar [Figure 1]b]
- Force was applied with an elastic chain that was attached from the button on lingual side of mandibular first molar to the micro-implant [Figure 1]b].
| Discussion|| |
Adult patients with a severe scissor bite are generally managed by surgical-orthodontic correction.  Nonsurgical options for correcting posterior scissors-bite, include edgewise appliances, transpalatal arch with inter-maxillary elastics,  lingual arch appliances with intermaxillary elastics,  and modified transpalatal arch.  The distinct disadvantages of elastics are patient compliance and undesirable extrusive forces on anchor teeth.
In the present case, buccal uprighting of the mandibular premolars and molars was achieved with the help of micro-implants. Duration for the correction of scissor bite was approximately 7 months [Figure 1]c]. The patient discontinued the orthodontic treatment after correction of scissor bite due to his personal and professional reasons.
