Case Reports on Surgical Lengthening of the Clinical Crown
The goal of this case report is to show how important it is to use a simple way to lengthen the crown, making the restoration operation and appearance easier.
The long-term success of endodontically treated and restored teeth depends on maintaining good periodontal health. Many teeth have major structural flaws that make coronal restoration difficult. At the periodontal attachment level, extensive caries, tooth fracture, previous restorations, perforations, and external resorption can all impair tooth structure.
The periodontal attachment zone or biologic width may be encroached upon if a restorative margin is placed subgingivally. When the biologic width is breached, the periodontium responds by causing gingival inflammation, attachment loss, and alveolar bone resorption. Clinical crown lengthening can be considered as an alternative to orthodontic extrusion when sufficient tooth structure for a restoration is not available.
Two examples of short clinical crowns with poor gingival health are discussed. Following surgical crown lengthening, posts were implanted, and porcelain fused to metal crowns were fabricated, all of which resulted in results that were extremely pleasing to both the patients and the physician. In one example, four years of follow-up revealed stable gingival margins and outstanding aesthetics.
