    Welcome to our first 10-minute Clinical Quick Tips video, presented by Perio-Implant Advisory. Look for more videos to come in which we will present techniques and product demonstrations on real patients with an emphasis on solving periodontal- and implant-related issues.

    In this video, you will learn how to correct gum inflammation and bleeding around existing crown and veneer restorations with functional crown lengthening (figure 1). I will discuss biologic width and the importance of maintaining this space, the etiology and treatment of inflammation, and the steps involved in the functional crown lengthening procedure.

    I will also present a case example of a patient with anterior crown and veneer restorations that have invaded the biologic width, causing the surrounding gum tissue to become inflamed and bleed. You will see how I recreate this space through anterior crown lengthening by reducing the hard and soft tissue with a new 9.3-micron CO2 laser (Solea from Convergent Dental) in a closed flap technique. The intention of this procedure is to reduce postoperative pain for the patient by avoiding the necessity of large incisions and sutures.
