Thus, the purpose of this case report was to evaluate the performance of a novel fibersite preshaped abutment post in a canal space over the course of 1 year.

In such cases, preservation of dentin is during the root canal and post endodontic procedures are the prime factors to improve the clinical longevity and success of the final restoration. The known ideal method for restoration of devital teeth for the past two decade are very few that includes prefabricated or the custom made metallic-post and cores and full crowns. (1) Tooth-colored fiber posts were introduced in the 1990s and have several advantages over conventional metal posts. They are aesthetic, bond to tooth structure, have a modulus of elasticity similar to that of dentin but still require dentin preparation to fit into the canal. Lately, fiber reinforcement systems have been introduced in the attempt to increase RBC durability and damage tolerance. However this standard fiber post does not adapt well to a flared root canal preparation, leaving a large cement space between the post and the tooth structure. Direct anatomic posts are the one which provide an alternative technique for restoring these teeth with less chance of debonding. (2) Very few case reports have been reported on the technique used to reinforce the tooth using prefabricated anatomical post. (3) This case report describes the novel method of anatomical post placement in severely damage devitalized teeth in maxillary left central incisor with 2 year follow-up. Case Report A 30-year-old female patient reported to the department of conservative dentistry and endodontics with a chief complaint of caries in upper front tooth region for the past 2 years. Medical history of the patient was non-contributory. On clinical examination the tooth was discoloured and grossly decayed and there were no sign of sinus tract in relation to tooth 21 [Fig.1a]. Radiographic examination revealed dental caries involving the pulp and radiolucency involving the apex of the tooth 21 [Fig.3a]. Pulp sensibility test of the same tooth with an electric pulp tester (Ashoo Sons API Pulp Tester, Delhi, India) showed negative response. Based on the clinical and radiographic findings, tooth 21 was diagnosed as irreversible pulpitis with periapical abscess. Root canal treatment followed by post and crown was advised for the afore-mentioned tooth. Two treatment protocols were explained to the patient before the endodontic treatment i.e., cast post with crown and tooth reinforcement with fiber post and crown. Due to lose of extension of the crown structural, reestablishment of the lost crown structure was needed for aesthetic and functional recovery. The patient was economically affordable opted for fiber post. With the patients consent, the treatment of maxillary left central incisor was initiated with endodontic treatment followed by Fibersite (Megadenta ltalia) fiber post placement (Fig. 4). Procedure Caries removal was done before the root canal procedure [Fig. 1b, 1c]. Access opening was performed on left maxillary central incisor and working length was determined radiographically. The apical preparation was done until 60 K file and corresponding gutta percha was selected as master cone. Obturation was performed with lateral condensation technique and was seared at the cement-enamel junction. Later, with the help of no- 2, 3 gates glidden drills, the guttapercha was removed leaving 5 mm intact in the apical region [Fig. 3b]. The post space was prepared with 0.4 drill given by the manufacturer [Fig. 1d]. The coronal part upto the CEJ was further shaped with the help of bur guide, which
