A Comparative Evaluation of the Fracture Resistance of Mineral Trioxide Aggregate (MTA) Plus and MTA Angelus: An In Vitro Study.

Background Mineral trioxide aggregate (MTA) is a biocompatible dental material used for root-end filling in endodontics. A wide variety of literature has been published on the assessment of fracture resistance of MTA. However, the results were conflicting in the reported studies, and the sample size used was insufficient to conclude the efficacy of materials such as MTA Plus and MTA Angelus.

Two-step impression for atrophic mandibular ridge.

The clinical difficulties encountered while treating edentulous patients with atrophic mandibular ridges are legion. Capturing tissue details while making an impression of a resorbed mandibular ridge poses a great clinical challenge. Extending the denture bases adequately to cover all of the available supporting tissues is one of the prime requisite.

A technique to achieve predictable iris positioning and symmetry in ocular and orbital prostheses.

An alternative technique for achieving predictable iris positioning and symmetry for ocular and orbital prostheses using a mounted graph grid is proposed.
