Another Use for Anterior BruxZir® Solid Zirconia Restorations

Another Use for Bruxzir Restorations - CE Course
Launch Course

Course Objectives (2 CE Credits)

Michael C. DiTolla, DDS, FAGD

One of the most difficult situations restorative dentists face in clinical practice is treating a patient with tetracycline-stained teeth. Zirconia, which has recently become a popular dental material due to its high strength, resistance to fracture and ability to mask discolored underlying tooth structure, is well suited to these types of cases — especially if the patient shows increased wear or has broken other ceramic restorations. In this presentation, Dr. Michael DiTolla demonstrates the placement of BruxZir® Solid Zirconia (Glidewell Laboratories) crowns in the anterior to esthetically restore a patient with severe tetracycline staining and an extreme bruxing habit. Participants who view the presentation will acquire useful clinical information on many topics, including:

  • An anesthesia technique benefitting both dentist and patient
  • The Reverse Preparation Technique
  • Gingival retraction using cord vs. paste systems prior to impression-taking
  • Indirect temporization using BioTemps® Provisionals (Glidewell Laboratories), including relining and cementation techniques
  • Placement of BruxZir Solid Zirconia crowns in the anterior
  • Demonstrations and recommendations of dental instruments and materials
  • Tips for achieving better-fitting crowns with improved esthetics

Summary

Dr. Michael DiTolla details the use of BruxZir Solid Zirconia restorations in the anterior to esthetically restore a chronic bruxing patient with severe tetracycline staining in this clinical presentation. As demonstrated in the case example, BruxZir Solid Zirconia arguably provides the best material option for this type of case due to its high flexural strength and resistance to fracture, as well as its ability to mask dark underlying tooth structure more completely than other restorative materials currently available. Clinical technique tips are discussed using detailed images of the various steps undertaken during anesthetization, preparation, gingival retraction, impression-taking, indirect temporization and final restoration.

CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
