Surgical guides for esthetic crown lengthening procedures

The crown lengthening double guide and the digital Perio analysis

“…1 In addition, optimal fit, ease fabrication, and time-efficient procedure have been reported among the advantages of the technique. 1 The facially driven and biologically oriented planning associated with the 2D simulation and 3D guide design allows the clinician to propose and perform a less operator-dependent procedure because the decision of how much and which tissues should be removed is oriented by the Perio Analysis measurements. Hence, the digital visualization of the patient gingival phenotype and biological width is mandatory, which can be obtained with CBCT exam with lip retractor and intraoral scan.…”

“…The main factors for the success in esthetic crown lengthening procedures include the achievement and maintenance of ideal gingival margin levels and architecture, which are influenced by biologic requirements 15 . The digitally obtained double guide provides proper soft and hard tissues management and, therefore, reduces the chances of under‐or overcontouring of these tissues, facilitating predictability, reproducibility, and long‐term pleasant outcomes 1 . In addition, optimal fit, ease fabrication, and time‐efficient procedure have been reported among the advantages of the technique 1 …”

“…The use of a digitally designed double guide for crown lengthening has been successfully reported elsewhere. 1,[16][17][18][19][20][21] However, further studies should evaluate the accuracy of surgical guides for crown lengthening procedures and the influence of several factors such as scanner protocol and systems, guide errors or misfits, different resins, 3D printers, and software systems. 17,18 In addition, clinical trials are needed to validate and confirm the reliability and repeatability of this technique.…”

“…The excessive gingival display is a multifactorial condition, often referred as "gummy smile," that requires accurate diagnosis and treatment planning for achieving long-term esthetic outcomes. 1 To improve tooth exposure and reestablish the biological width, a surgical crown lengthening is required, which comprises gingivoplasty and osteotomy. 2 Due to the increasing digitalization of dentistry in recent years, countless novel concepts have emerged, leading to new ways of diagnosing, planning, communicating, and performing dental treatments.…”
