3D Printed Implant for Management of Gummy Smile Through VISTA Technique

the most important esthetic concern for dental patients is excessive display of gingiva during smiling due to multiple causes e.g. hyperplasia of gingival, skeletal overgrowth of the anterior maxilla, altered passive eruption, maxillary alveolar tooth extrusion, short lip and lip hypermobility therefore accurate diagnosis of these factors is essential before treatment to ensure the most suitable approach is chosen. Maxillary overgrowth may cause sub nasal skeletal depression that lead to retraction of upper lip during smiling, causing gingiva display. The aim of this study is to describe an alternative technique to treat gingival smile with minimally invasive vestibular incision subperiosteal tunnel access (VISTA) to place 3D printed polymethylmethacrylate (PMMA)-based bone cement versus polyether ether ketone (PEEK) for lip repositioning.
