Crown Lengthening
Faced with a cusp fractured below the gingiva?
Prepping too far under the gingiva and not getting
predictable impressions?
Planning esthetic restorations in the anterior and facing
uneven tissue or a “Gummy Smile?
Creating Predictable Restorations
Crown extension is one of the most commonly required procedures in restorative dentistry, yet it is often underutilized. Enjoy an in-depth look at the evidence-based concepts and practical applications for Clinical Crown Lengthening and learn how to enhance predictability for your restorations and impressions. Gain the peace of mind that you are current in your treatment planning choices.
Techniques are discussed for both Functional and Esthetic Crown Lengthening. Including: how to handle hard and soft tissues; proper surgical techniques; preservation of esthetics in the final tissue contours; and relocation of all structures that comprise the biologic width, namely: sulcus, junctional epithelium, connective tissue fibers, and bone.
This course includes hands-on exercises and many case illustrations, plus two video demonstrations of surgical technique. The full day workshop offers the opportunity to practice these procedures on pig jaws and anatomically correct models.
The workshop is suitable for clinicians with or without surgical experience, who want to do some or most of their own crown extensions or just want to know more about the subject.
Participants will learn:
- How to make predictable impressions every time
- Why crowns come loose and how to prevent it
- Methods that save chair time and increase profit
- Causes of red gum tissue around margins
- How to diagnose esthetic crown lengthening
- To understand the Gummy Smile
- How to coordinate surgery with restorative procedures
Note: Workshop participants receive a workbook detailing the procedures.
