The most important aim of endodontics is the preservation of natural teeth. Accurate working length determination is a crucial part of successful endodontic treatment. It is said that "Apex is the essence of endodontics." There are certain important features at the apex of the tooth with which one needs to be familiar if an accurate working length is to be determined. If calculated within correct limits, working length will play an important role in determining the success of the treatment, and conversely, if calculated incorrectly may doom the treatment to failure. Therefore it can be seen...

In present work advancement in replication techniques for a biomedical component having a real 3D shape has been introduced. A hip joint was selected as one of a real 3D biomedical implant for this study. A hip joint, made of ABS material, was fabricated as a master pattern by fused deposition modelling (FDM) method. After this mold was made by the deposition of Primary, Secondary and Tertiary coatings with the addition of (1- 2cm in length) nylon fiber of 1.5D as per the Taguchi L9 control log of experimentation.This study outlines complete replication procedure of hip joint in detail from...
