Ideal smile aesthetics includes ‘pink’ aesthetics and aesthetic crown lengthening surgery is an integral surgical procedure that is commonly used to achieve optimal overall aesthetics. Understanding the reasons for a ‘gummy’ smile, or gingival excess, is key. A thorough assessment and careful treatment planning are required for successful results. Crown lengthening can be carried out as a stand-alone procedure or as part of a wider restorative treatment plan.
CPD/Clinical Relevance: This article discusses the ideal ‘pink’ aesthetics, indications for crown lengthening as well as the treatment sequence.
Article
With an increase in patient demand for achieving the most optimal smile aesthetics, the field of periodontology has also evolved to have a greater focus on periodontal plastic surgical procedures to achieve the required ‘pink’ aesthetics as part of this. One of the most popular treatments is aesthetic crown lengthening. Crown lengthening surgery can be used to address ‘gummy smiles’, uneven gingival contours and can enhance the appearance of restorations placed within the aesthetic zone.
A smile is generally defined as pleasant when it exposes the entirety of the maxillary teeth along with approximately 1 mm of facial gingiva. Gingival exposure of up to 2–3 mm is normally found acceptable, whereas patients are usually dissatisfied with any greater exposure (>3 mm).1 Patients with a high smile line who expose a large band of gingiva may be classified as having a ‘gummy’ smile (Figure 1).
