Die Therapie von Kronenfrakturen bei Frontzähnen – Reattachment statt Restauration?


Wiegand, A; Rödig, T; Attin, T (2005). Die Therapie von Kronenfrakturen bei Frontzähnen – Reattachment statt Restauration? Schweizer Monatsschrift für Zahnmedizin SMfZ, 115(12):1172-1181.

Abstract

Crown fractures are the most common form of traumatic dental injuries in the permanent dentition. Reattachment of the coronal fragment to the remaining tooth structure may offer a conservative, esthetic and cost-effective restorative option which has been shown to be an accepted alternative to conventional restoration (resin composite build-up, veneer or crown) of the fractured teeth. Fragment retention is significantly influenced by reattachment techniques and materials. Regarding reattachment techniques, placement of an internal groove seems advisable when the remnant and the fragment fit well, while an overcontouration should be used when the partial loss of hard tissue must be compensated. Materials used for reattachment seem to be less important than technique for a successful treatment, but adhesives and composite resin materials should correspond to each other. However, up to now, self-etching adhesives have shown less fracture strength of the reattachment than multi-bottle adhesives. Since many case reports and several clinical studies reported clinical success, further studies are recommended to analyse the impact of reattachment techniques and materials on the long-term survival of fragment bonding.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
