Orthodontic Extrusion as Treatment Option for Crown- Root Fracture: Literature Review with Systematic Criteria

Abstract

Objective To review the literature searching for a consensus for the choice of orthodontic extrusion as treatment for crownroot fracture. Materials and methods An electronic search was performed in the databases PubMed, Cochrane Central Register of Controlled Trials and Scopus and a manual search of the Journal Dental Traumatology. Results Forty articles were found in PubMed and 38 in Scopus and after removal of duplicate sample 51 contained articles. Of these, 48 were excluded for not having orthodontic treatment, no follow-up or follow-up less than 6 months, or not report the presence of crown-root fracture. In manual search in Dental Traumatology 20 articles were found, but none of them met the prerequisites established. So, three articles formed the basis of the study. Conclusion The choice of how to treat orthodontic extrusion of crown-root fracture was effective and stable, without root and periodontal changes. Factors, such as root formation and presence of pulp vitality were decisive for determining the stages of treatment, however, there is no consensus based on scientific evidence about these protocols.

Kronen-Wurzelfrakturen lateraler Inzisivi – Erhaltung von vitalen und avitalen permanenten Zähnen durch kombinierte kieferorthopädisch-endodontische Therapie

“…Neben chirurgisch-resektiven Maßnahmen zur Freilegung der Defektgrenze, können auch kieferorthopädische Behandlungsmethoden sinnvolle Alternativen darstellen [4]. Hierzu zählen langsame kieferorthopädische Extrusionen mit geringen Kräften [17], forcierte kieferorthopädische Extrusionen [18] und chirurgische Extrusionen [19], wobei diese Verfahren je nach klinischer Ausgangssituation unterschiedliche Vor-und Nachteile aufweisen.…”

Orthodontic Forced Eruption of Permanent Anterior Teeth with Subgingival Fractures: A Systematic Review

“…A systematic review published five years ago concluded that OFE is an effective approach to the treatment of teeth with crown-root fractures that provides stable results [ 19 ]. However, that review was based on the outcome of only three case reports.…”

Effects of different splinting times on surgically extruded teeth with a crown‐root fracture: A randomized controlled trial

“…Alternatively, orthodontic extrusion can be used to expose the fracture line for restoration of the tooth. Unfortunately, this approach has limitations, including patient acceptance, increased costs, prolonged treatment duration and risk of relapse 6,7 . Surgical extrusion is a straightforward and time‐saving treatment option for the management of crown‐root fractures, and it was initially described as an alternative to orthodontic extrusion 8,9 .…”
