As you have gathered by now, there are numerous types of space maintainers. Each different space maintainer is used in different clinical situations.

We will review an array of different clinical situations relating to space maintenance therapy and give our recommendations for each of these situations. Hopefully, going through these clinical exercises will result in an understanding of when space maintenance is indicated and what type or types of space maintainers might be used. We will attempt to cover virtually every generic type of clinical situation requiring space maintenance therapy which clinicians will encounter in the primary and mixed dentitions.
