Recent years have seen a continuous increase in the demand for zirconia dental implants as a result of growing public health awareness and a surge in material sensitivity cases. For one thing, zirconia implants elicit little inflammatory reaction from the peri-implant tissue and provide a particularly high degree of epithelial attachment. In addition, zirconia implants have a rather natural appearance owing to their white, almost tooth-like color, facilitating highly esthetic treatment outcomes. For these reasons, among others, zirconia implants pose a viable treatment option for restoration of missing teeth or the replacement of failing restorations in the anterior region. However, implant placement in the esthetic zone can pose significant clinical challenges. In cases with atrophic changes to the alveolar crest or limited space (especially in the anterior mandible), narrow-diameter implants might be indicated. In the following, Zurich-based dental implant specialist and researcher Dr Roland Glauser presents a clinical case in which a failing post and core restoration in the anterior mandible had to be removed and restored using a narrow-diameter zirconia implant and a crown. The manufacturer of the implant system used offers the possibility of designing dental implants individually using proprietary software, allowing Dr Glauser to tailor the planned implant to the anatomical conditions of the patient.
