Use of quartz fiber post for reattachment of complex crown root fractures: A 4-year follow-up.

Dental hard tissue trauma is among the most common cases encountered in dental practice. Simple tooth fractures, which occur due to sharp blows, are widely seen in all age groups, especially in young adults. If in case of complex fractures the fractured tooth fragments are available to the dentist in a clean and hydrated state, reattachment of the tooth fragment is the most conservative and biological treatment option possible.
