The infringement of biologic width is clearly visible in Figure 3 -there was hardly any presence of gingival sulcus. After removal of the unsatisfactory crowns, this suspicion was confirmed. The infringement of biologic width due to the crown edges lying too close to the bony alveolar ridge ( Limbus alveolaris) could mean a case of iatrogenic, chronic, marginal periodontitis. The reason for gingival inflammation stemmed from the poor marginal fit of the existing crowns and the edges of the crowns protruding far into the subgingival region. An injury to the gingival structures could not be identified in the initial examination however, with more precise examination, an inflammatory alteration to the gingiva in the anterior region was visible. There was a periodontal biotype B, ie, a “robust” periodontium. The periodontium seemed healthy at first glance. ![]() The original crowns had been in place for 15 years and were no longer functioning in total harmony with the patient’s natural dentition. 13 to 23 were fitted with all-porcelain crowns ( Figure 1 and Figure 2), which were not loosened, and no pathological findings were revealed with the primary and X-ray examinations. In order to better facilitate communication and teamwork, the clinical aspects were intentionally taken into consideration and highlighted at the presentation of the case.Īt presentation there was no presence of functional discomfort, and dental hygiene was good. This motivated the patient to get his anterior teeth re-crowned. In addition, the patient’s wife previously had prosthetic treatment with the authors and was very satisfied with the results. He was unhappy with his old crowns as the color and shape no longer met his esthetic requirements. In this case report, the authors demonstrate their well-coordinated teamwork for restoring six maxillary anteriors with zirconia-supported crowns.Ī 70-year-old man consulted the dental practitioner regarding his desire to replace his anterior crowns, which had been fitted 15 years previously. Nor is it practiced in the interaction between dental technology personnel and dental health professionals. While this term is sufficiently well-known in the world of specialists, it is still not practiced by many dental practitioners. This is where the monitoring of “biologic width” plays an important role. ![]() Successful results can only be established on a healthy foundation. The patient’s desire to have perfect teeth must be accompanied by the clinical responsibility of the treatment team.
