The Double-sided Intrusion Spring

In deep bite cases, proper planning and practice are important in achieving the successful treatment outcomes. Bite opening is obtained with the aid of incisor intrusion, molar extrusion, or a combination of them. Pure incisor intrusion is a challenge for clinicians because incisor intrusion mechanics generally cause molar extrusion or incisor flaring. In the present article, a new technique that can be used for incisor intrusion without the mentioned handicaps was introduced.
