Restoration of root-treated teeth is routinely performed in clinical practice with a choice of therapeutic options, considering many factors to provide optimal mechanical properties, esthetics, and longevity. The aim of the present work was to present a preliminary clinical report on the use of fiber posts and direct resin composites for restoring root-treated teeth. Thirty-eight anterior and 62 posterior endodontically treated teeth were selected from 3 private prosthodontic offices. The protocol used included endodontic treatment, with translucent fiber posts (DT post) bonded to the post-space using a '1-bottle' adhesive (One-Step, Bisco) and a dual-cure resin cement (DuoLink, Bisco). Direct resin restorations were performed using a micro-hybrid resin composite (Gradia Direct, GC) and a layering technique. Both opaque dentin and enamel and translucent enamel shades were used. Patients were recalled after 6, 12, 24, and 30 months, and the restorations assessed according to ...

Background. Esthetic appearance of primary anterior teeth is one of the major demands in the dental field. Destructed anterior primary teeth due to caries is considered a major issue due to the difficulty in regaining the esthetic crowns and attaching them until the normal exfoliation time. There have been many attempts and tools used to attach the composite crowns to the treated canals of primary anterior teeth. The study evaluates endodontic treatment for destructed primary maxillary incisors with a glass fiber-reinforced post as a retentive tool to hold the esthetic composite crowns until the normal exfoliation time of primary incisors. Case Presentation. A four-year-old child attending a dental clinic complained of pain of maxillary incisors. Dental examination showed irreversible pulpitis of four maxillary incisors indicated for root canal treatment and crown placement. Endodontic treatment was carried out, and a glass fiber-reinforced post was used to get successful retention ...
Restorative perspective for endodontically treated teeth: Anatomic post
Dental Press Endodontics, 2014
Introduction: Individualized anatomic posts favor adaptation of prefabricated posts to root canal walls and reduce resin cement thickness. Objective: The aim of this study was to report a case of reconstruction of previously endodontically treated teeth by means of an individualized anatomic post. Methods: Replacement of endodontically treated central incisor restorations and previous deficient restorations was reported. Initially, deficient resin composites and the individual cast post of tooth #11 were removed. Root canal was endodontically retreated. The amount of residual dentine walls of the root canal were low after removing the endodontic post. Treatment plan included the use of an anatomic post for tooth #11. Composite resin was applied after anatomic post placement. Root canal was shaped by a glass fiber post and composite resin. Subsequently, crown restoration was completed with composite resin. Conclusion: The technique used to manufacture direct anatomic posts seem to be a good alternative treatment for restoring wide root canals.

The long term prognosis of an endodontically treated tooth depends on the strength of the remaining tooth structure and the prosthetic restoration of the same. The use of aesthetic materials becomes mandatory while restoring the teeth in the aesthetic zone. A restoration of an anterior tooth with Glass fibre post, along with dual cure composite core followed by a Lithium Disilicate crown is presented. The restoration addressed the patient’s chief complaint of a broken and ugly anterior tooth while preserving maximum remaining tooth structure and achieving optimum aesthetic results. This allowed a smooth transition from an unaesthetic, fractured tooth to an interim restoration in a single appointment, followed by the definitive metal free crown on a subsequent date.

Introduction: Restoration of primary incisors, which have been severely damaged by extensive caries or trauma, is a difficult task for the Pediatric dentist. Primary teeth dictate the physical appearance, and their structural affects leads to loss of esthetics compromised mastication, poor phonetics, development of aberrant habits, neuromuscular imbalance, and difficulty in socio-psychological adjustment of the child. Case description: This Case Report discusses the restoration of severely decayed primary maxillary incisors using composite resin restoration reinforced with Glass impregnated post in anterior teeth in a 4 years old male patient. Discussion: The use of intracanal posts in endodontically treated teeth improves the retention of a eventual restoration. The use of impregnated fiber glass post together with flowable composite offers an alternative where all components are bonded together to form a firmly attached restoration. Conclusion: The technique of using glass impregnated composite resin as post and core has shown promising results and has presented Pediatric dentists with an additional treatment option.
Clinical evaluation of teeth restored with quartz fibre-reinforced epoxy resin post
The International journal of prosthodontics
B oth researchers and manufacturers have introduced several post-and-core restorations with the aim of providing reliable systems for reconstruction of endodontically treated teeth. In spite of these efforts, it is still difficult to predict the clinical survival times of treated teeth restored with posts and cores. The prognosis is related to several factors, including the type of material used for the post and core; the shape, dimensions, and length of the post; and the kind of cement used. The major disadvantage associated with conventional cast-metal posts is vertical root fracture. Having high rigidity, metal posts appear to vibrate at high frequencies when loaded with lateral forces. The focusing of these forces in unpredictable "critical points" may determine longitudinal fractures of the root or metal corrosion 1 and consequently lead to loss of the tooth. In 1990, Duret et al 5 proposed carbon-fiber posts, among the many prefabricated fiber post-and-core systems, to reduce the failure rate. These relatively recent posts are made of equally aligned carbon fibers attached to an epoxy resin matrix and present an interesting property, anisotropic behavior. In other words, the material has different physical responses when loaded in different directions. This characteristic is of clinical relevance, as it may strongly reduce the possibility of root fracture and decementation. The objective is to create a "cement-post-core" system with homogeneous properties and physical characteristics similar to tooth tissues. To fulfill esthetic requirements, quartz-and glass-fiber posts embedded in a filled resin matrix have been developed.
Post-endodontic rehabilitation using glass fiber non metallic posts: A review; | dr vineet vinayak|
Abstract Generally endodontically treated teeth have already undergone significant coronal destruction, loss of radicular dentin and an overall reduction in the capability of the tooth to resist intra-oral forces. The high success rates in modern day endodontics has resulted in an increased demand for an aesthetically convenient post and core system to help restore loss tooth structure. While the metallic post and cores provide a time-tested fulfillment of replacing the missing coronal tooth structure sufficiently to provide the required retention and resistance for the final restoration, yet aesthetic compatibility with the tooth structure is often compromised. Another important issue that is often not taken into consideration while using metallic posts is retreivability, when a metallic post fractures or fails, it is often virtually impossible to remove the residual post from the radicular portion of the tooth without greatly compromising the remaining dentin. Recent development in the field of esthetically viable non-metallic endodontic posts has served to erase these predicaments by providing an esthetically pleasing, easily retrievable post and core anchorage to replace the missing coronal tooth structure. This paper highlights the objectives, advantages and clinical predi- ctabilities in using a luscent glass fiber non-metallic post , thus providing an endo-aesthetic restorative continuum for both the patient and the dentist.

Fiberglass posts have shown better retentive properties and greater displacement strength compared to orthodontic wire γ-posts and better retentive features than composite posts. 26,27 Motisuki et al. 24 observed that after a 1-year period, fiberglass posts supported composite restorations provided better retention IntroductIon The occurrence of caries in the deciduous maxillary anterior is regularly identified with breast or bottle feeding at night, unsatisfactory oral hygiene, and consumption of a refined carbohydrate-rich diet after weaning. 1 Badly destroyed anterior teeth may lead to speech difficulty, diminished chewing efficiency, malocclusion due to improper movement of the tongue, and decreased confidence. 2 Therefore, saving the integrity of the deciduous dentition is critically important until they exfoliate normally. Treatment of extensively broken down primary anterior teeth in children with limited cooperation is considered a formidable task for a pediatric dentist. 3 Since there is a scarcity of adequate tooth structure to provide adhesive reinforcement for restoration in such teeth, pulpectomy and use of intracanal posts may be required prior to restoration. The intracanal posts enhance the resistance of the restoration to mechanical loads to masticatory forces. 4 Various materials used for intracanal retention include resin composite posts, 5-12 orthodontic wires, 5,8,10,13-16 prefabricated metal posts, 17 nickel chromium cast posts with macro-retentive features, 18 biologic posts, 10,19-21 and reinforced fibers. 4,22-26 Glass fiber posts allow for the raised passing of light through the root and the overlying gingival tissues. Additionally, they help in getting rid of corrosion that can happen with prefabricated metal posts. One of their key attributes is the elastic modulus, which is almost the same as that of dentin, resin cements, and core materials. 10

Aim: Comparative evaluation of the fracture resistance of endodontically treated maxillary central incisors restored with prefabricated glass fiber posts and experimental dentin posts prepared human root dentin. Materials & method: Thirty six extracted human Maxillary central incisors were divided in to three groups. In Group-I (Control group) 12 samples, Group-II (Glass fiber posts)12 samples, Group-III (Dentin posts) 12 samples. Twenty four teeth were restored with Glass fiber posts and Solid dentin posts and numbered as Group-II and Group- III respectively while Group-I acted as a control, without any posts only core build up. Teeth were loaded at 130º angle to their long axes after core build up and the failure load were recorded. Result: Statistical analysis showed that Group III (Dentin posts) (120.9 ± 1.447) and Group II (Glass Fibre posts) (118.6±1.437) the mean failure load value was significantly higher than Group I (Control group) (59.71±2.684). There had no statistically significant difference between group II (Glass fiber posts) and group III (Dentin posts) (Table-1) (Graph-1). Conclusion: Teeth restored with the dentin posts exhibited marginally better fracture resistance than those restored with glass fiber posts.
Four-year Survival of Endodontically Treated Premolars Restored with Fiber Posts
Journal of Dental Research, 2014
The objective of this prospective clinical trial was to investigate the influence of the residual coronal structure of endodontically treated teeth and the type of cement used for luting fiber posts on four-year clinical survival. Two groups (n = 60) were defined, depending on the amount of residual coronal dentin after abutment build-up and final preparation: (1) more than 50% of coronal residual structure; and (2) equal to or less than 50% of coronal residual structure. Within each group, teeth were randomly divided into 2 subgroups (n = 30) according to the material used for luting fiber posts: (A) resin core build-up material, Gradia Core; or (B) self-adhesive universal cement GCem Automix. The rate of success was assessed based on clinical and intra-oral radiographic examinations at the follow-up after 6, 12, 24, 36, and 48 months. The highest 48-month success and survival rates were recorded in group 1A (90% and 100%, respectively), whereas teeth in group 2B exhibited the lowe...
