[A PhD completed 1. Immediate dental implant placement in the aesthetic zone].

When aesthetics play a role in an extraction, the tendency is to place an implant in the extraction socket immediately, preferably in combination with a temporary crown. This tendency is probably related to evolving social factors: demanding patients who want an instant and attactive result. In 2 randomised clinical trials (total 80 patients) the results of clinical treatment involving immediate implants in the aesthetic zone are investigated. Depending on the size of the bone defect (< 5 or ≥ 5 mm) the number of surgical interventions was reduced from 2 to 1 or from 3 to 2. The treatment result was measured by the following outcome variables: survival rate, changes in hard and soft -peri-implant tissues, aesthetic indecees and patient-satisfaction. The most important conclusion is that immediate placements of implants in the aesthetic zone, results in -outstanding short-term (1-year) results with respect to the outcome variables. If this also leads to good long-term results has yet to be investigated.
