Introduction

Prosthodontics Dental Prosthesis is the area of dentistry that deals with the modification of pathological natural teeth and the replacement of lost teeth as well as preventing future pathologies.

The study of Fixed Prosthodontics addresses the different kinds of treatments involving fixed prosthesis and how the dental preparations should be carried out to achieve good functional and aesthetic results.

Pre-course requirements

Dental anatomy. Knowledge of the pathophysiology of the patients who have lost all or some of their teeth. Knowledge of the anatomy and functions of the dental structures.

Objectives

The aim of this course is to ensure that students acquire the basic theoretical and practical knowledge regarding the different types of restorations using fixed protheses and the preparations that will ensure good results.

Competencies

  • CB10 - Students should acquire the learning skills that allow them to continue to study.
  • CB6 - Students should have and understand knowledge that provides the basis for or opportunity to be original in terms of the development and application of ideas, often within a research context.
  • CB7 - Students should know how to apply the knowledge they have acquired and be able to resolve problems in new or little known environments within a broader (or multidiciplinary) context, related to their area of study.
  • CE4 - To acquire the ability to make oral preparations on mucosa, teeth, and dental implants, to build dental prostheses in patients with advanced oral and multidisciplinary disorders; as well as identify and undertake the procedures and various checks for the prosthetic components during construction.
  • CE5 - To be able to give public presentations on your own clinical cases based on the scientific literature, and correctly use the scientific terminology related to temporomandibular dysfunction and aesthetic restorative dentistry.
  • CE7 - To be able to search for, organise and analyse, from a critical point of view, and using biomedical sources of information, scientific literature on issues related to temporomandibular dysfunction and aesthetic restorative dentistry, in order to pursue continuing education in a self-directed and autonomous way.
  • CG4 - To know how to apply protocols for the use of the equipment in the dental laboratory-workshop to the point of undertaking the necessary procedures that help in oral rehabilitation or the treatments common to a restorative dentist.
