Orthodontic Extrusion For proper Endodontic therapy 

Fig. 1

A 40-years-old female patient presented to my private dental clinic with fracture of palatal cusp of upper right first premolar. 

Clinical examination showed fractured line extended sub-gingival on the palatal side making the prosthetic rehabilitation difficult.

The main objective of the treatment was to restore the traumatised tooth in respect to all biological, functional and aesthetic principles of all the treatments involved.

However, as tooth isolation was not possible due to the deep fracture, lengthening of the clinical crown had to be performed. It was decided that orthodontic extrusion was the best and most conservative option. Orthodontic brackets was positioned in its place and more apically on fractured tooth. The time required for wire application is one month and 3 weeks for power chain.

Minor gingival re-contouring was carried out in order to have a symmetrical gingival margin.

The coronal extrusion was considered satisfactory as the fractured site had reached the free gingiva level, allowing for a qualitative RDI. Orthodontic wire was removed.
