Altered Apical Morphology (Reverse Architecture)‎: Use of Indirect Ultrasonic Technique for Orthograde MTA Placement in Maxillary Premolars

Abstract EN

Aim.

To report the management and orthograde technique of MTA placement in case of reverse architecture maxillary premolars.

Summary.

Two cases of 17-year-old and 21-year-old female patients were referred to endodontic speciality for management of maxillary premolar having reverse architecture with wide immature open apex like a bell mouth.

In both the cases, after control of intraradicular infection, it was decided to use MTA for apexification and obturation of canals.

Orthograde placement of MTA is a challenging procedure in terms of length control and condensation especially in divergent irregular reverse architecture wide open apex.

A novel technique with the help of finger plugger, sterilized paper point, and ultrasonic agitation for 3D compaction of MTA at apical reverse architecture was used.

Thickening of the canal wall and complete apical closure were confirmed one year after the treatment.
