This technique article describes an approach to managing excessive gingival display by lengthening of the clinical crowns using a digital workflow. An intraoral scanner was used to obtain a template to be used for the crown lengthening surgical procedure considering the patient-desired diagnostic setups while fully seating the template on the patient's teeth during surgery. Using a digital approach for lengthening the clinical crowns decreased the likelihood of the need for postsurgical modifications, thus shortening the treatment duration. After the crown lengthening healed for 12 weeks, full-mouth reconstruction proceeded. Maxillary and mandibular preparation reduction guides were digitally designed and printed to facilitate conservative crown preparations. An intraoral scanner was used to make full-arch scans and interocclusal records for the fabrication of provisional and final crowns. Fully guided implant planning and placement were also executed.
