The immediate fragment reattachment is a conservative treatment which allows the restoration of the original dental anatomy thus rehabilitating function and esthetics in a shortest time available. Dentists are confronted with managing dental trauma and restoring fractured teeth on a regular basis. Hence, the technique that speed and simplify treatment, restore esthetics and improve long-term success rate are therefore of potential value and should be considered. Fracture reattachment possess challenging conservative and economically viable procedure within a single visit. This article discusses fragment reattachment technique and presents clinical case of coronal fracture involving enamel, dentin, and pulp.

Crown fracture has been documented to account up to 90% of all traumatic injuries to the permanent dentition. Many epidemiologic studies show that most dental injuries involve just one tooth and maxillary incisors are the most commonly affected.[1],[2] It has been reported males are more frequently affected than females, particularly in the maxillary incisors.[3] An alternating treatment option for restoring fractured incisors is using bonding agent for the chipped fragment onto the natural crown. The first published case of reattaching a fractured incisor fragment was reported in 1964 by Chosack and Eidelma[4] when clinicians described a case of rehabilitation of a fractured incisor using the patient's original tooth. After these, many articles have been published regarding a variety of preparation designs and materials for reattachment. Dental injuries usually affect only a single tooth; however, certain trauma types such as automobile accidents and sports injuries involve multiple tooth injuries.[5] A number of techniques have been developed to restore the fractured crown. Early techniques include stainless steel crowns, basket crowns, orthodontic bands, pins, pin retained resin, porcelain bonded crowns, and composite resin.[6]

Some of the advantages from reattachment of fractured tooth fragment are:

Conservation of tooth materialColor matchingPreservation of incisal translucencyGood estheticsMaintenance of original tooth contoursEconomicalPreservation of occlusal contactsColor stability of enamelPositive emotional and social responses from patients.

Disadvantages of fragment reattachment are:

It may result in a change in color due to inadequate rehydration of the fragment; andIt carries the possibility of detachment of the fragment.

The objective of this case report is to present the reconstruction of a traumatized and fractured right maxillary central incisor by building a composite resin core with a glass fiber post.

 Case Report

A 40-year-old male patient reported to the department of conservative dentistry and endodontics of pacific dental college with a chief complaint of a fractured left maxillary central incisor because of trauma sustained during fall [Figure 1]. He did not have swelling or hemorrhage in the related area, and his medical history was noncontributory. Radiographic examination of the tooth revealed fracture line involving the enamel, dentin, and pulp [Figure 2]. The patient was immensely concerned about the immediate restoration of esthetics. Hence, we decided to restore esthetics immediately by reattaching the original crown fragment after ruling out periodontal damage, root fracture, and bony fracture. The fractured segment was removed atraumatically [Figure 3]. To prevent dehydration, the original fragment was kept in Hanks balanced salt solution till the completion of root canal treatment and post preparation. After completing the endodontic treatment followed by sectional obturation [Figure 4], postspace preparation was done both in the coronal fragment as well as in the root canal for proper retention of the fractured fragment assembly. Glass fiber post was selected as the patient was concerned more about his esthetics. After etching, the adherent surface of the fractured fragment was attached to the glass fiber post, and subsequently, the whole assembly was then cemented to the root portion with flowable composite resin [Figure 5]. The restoration was light cured, finished, polished, and checked for proper contact [Figure 6]. The entire treatment procedure was completed in one sitting.{Figure 1}{Figure 2}{Figure 3}{Figure 4}{Figure 5}{Figure 6}


Traumatized anterior teeth require quick repair for both functional and aesthetic needs. By using the original tooth fragment to restore a fractured tooth, it is possible to achieve very good aesthetics. Traumatic injuries involving tooth fracture can be treated by reattachment of the tooth fragment using a dentine adhesive system to provide what is considered to the most conservative to restoration. Factors influencing the extent and feasibility of such repairs include the site of the fracture, size of fractured remnants, periodontal status, pulpal involvement, maturity of root formation, biological width invasion, occlusion, and time. The composite reinforcement technique, together with this light-transmitting post, had been widely used to functionally and esthetically restore compromised root-filled teeth.[7] Restoration with a post after endodontic treatment provides retention of a core to support the coronal restoration, especially with extensive tooth loss. Conventionally, these posts have been cast or machined from metals and can be grouped as active or passive posts.[8] Active posts derive their primary retention directly from the root dentine by the use of threads. Passive posts rely primarily on luting cement for their retention. The advantages of using the original tooth fragment over other materials include better color match, morphology, translucency, patient acceptance, and economical.[9]

It is acknowledged that the placement of traditional metal posts weakens the roots and leads to root fracture, or may lead to caries that may cause irreversible failure and extraction of tooth in some cases.[10] The reattachment of the crown fragment to a fractured tooth can be considered as the most conservative treatment and could be the first choice for crown fractures of anterior biological width invasion, occlusion, time, and resources of the patient. If the fracture involves 2/3 or more of the crown, a postreattachment is more commonly used.[11] However, this technique is not without limitations. First, the resistance to fracture gained after reattachment is only 50%–60% that of the intact tooth.

Second, the success of reattachment also depends on how dehydrated the fragment is, because the longer the fragment remains dehydrated, the lesser will be the fracture strength of the tooth; however, strength can be reinstituted by hydrating the fragment. Prolonged dehydration may present esthetic problems, like lighter tonality than the tooth remnant.[12] Return to original color may take time or may not occur at all. With remarkable advancement of the adhesive systems and resin composites, reattachment procedures are no longer a temporary/provisional restoration, but rather a permanent restorative treatment providing favorable prognosis.[13],[14] In the present case, the fragment was maintained in the oral cavity since the accident, which avoided desiccation and color change. Our case was followed up for 6 months without noticeable color change of the crown or periapical radiological changes. The patient continued with the reattached fragment as a permanent restoration.


Reattachment technique is the most conservative and biological method of restoring a fractured anterior tooth. Reattaching a tooth fragment with newer adhesive materials may be successfully used to restore fractured teeth with adequate strength, but long-term followup is necessary in order to predict the durability of the tooth-adhesive-fragment complex and the vitality of the tooth. This procedure helps us to preserve maximal natural tooth structure. Patient cooperation and understanding of the limitations of the treatment are of utmost importance for good prognosis. This procedure helps us to preserve maximal natural tooth structure. The need of the day is to educate the public to preserve the fractured segment and seek immediate dental treatment.
