The mixed dentition is often accompanied by transient malocclusions, such as a midline diastema. The general principle is to monitor development to ascertain the appropriate timing of possible intervention. The present clinical article reports the case of a seven-year-old boy who suffered from severe iatrogenic periodontitis of the maxillary incisors due to direct closure of a diastema by a rubber band. The incisors survived and exhibited periodontal and pulpal health at an eight-year review. Carefully-sequenced interdisciplinary management and co-operation, appropriate biomechanics aided by temporary anchorage devices, and a longterm follow-up are noted as key factors determining success when clinicians encounter such challenges.
