Reconstruction of endodontically treated teeth is common procedure in everyday clinical practice. It has great impact on prognosis of endodontically treated teeth, however, there is no consensus regarding the most predictable restorative procedure. Widely accepted procedure has included the use of post and core and crown. Nowadays, sound tooth structure preservation has become one of the most influencing factors in terms of survival rate of treated teeth. Therefore, direct restorations have become more advantageous as compared to crowns. This article is a review about conservative reconstruction of endodontically treated posterior teeth. The purpose was to give the guidelines for clinicians how to choose the most successful therapeutic procedure for each individual case.

Purpose: This clinical case discusses the step-by-step implementation of a core and a post system that uses a single resin composite material for cementation of a glass fibre post and core build up of a fracture endodontically treated maxillary left first premolar with gingivectomy as a crown lengthening procedure. Clinical considerations: Several materials and methods has been discussed in the literatures regarding restoration of endodontically treated teeth with minimal tooth structure left which require fibre post and core build up. Gingivectomy as a crown lengthening is also a common procedure that facilitates restorative dentistry. This case presents a restoration of a tooth with a short clinical crown by gingivectomy and post core build up by glass fibre post with a mono-block technique or core-and-post technique with dual cure composite resin as a luting and core build up material. Conclusion:Post and core is needed to restored tooth with little tooth structure remaining.Glass fibre post are prefabricated posts which makes it easy to manipulate and reduces chairs side time among other advantages. Use of single material system for post-and-core reduces the steps of manipulation and chair side time compared to conventional techniques. Clinical significance: More measures are required when different materials are used for post-cementation and core build-up, increasing the chair time and the number of interfaces between the materials. However, these shortcomings can be overcome by the mono-block technique where only one material is used for both cementation and core build up. Update Dent. Coll. j: 2021; 11(2): 38-42

The literature reports several materials for the restoration of endodontically treated teeth, with coronal destruction that requires an intra-root fiber post to stabilize the prosthetic part. The intra-radicular post of composite resin reinforced with fiberglass can be used as retainers in rehabilitating endodontically treated teeth due to their adhesiveness, pleasing aesthetics, and elasticity module close to the dentin less wear on the remaining structure. This clinical case reports the step-by-step application of dual resin cement (Rebilda DC Dentine - Voco) used as the cementation material of the post and material for the filling core in a single step, in an upper right lateral incisor. Moreover, it describes the advantages and indications of the post-and-core technique, also called “monobloc” which can be used in both anterior and posterior teeth. This protocol minimizes the adhesive interfaces, the chair time, and the steps of the clinical procedure.

Due to substantial loss of coronal tooth structure, corono-radicular stabilization is often required, especially in anterior teeth to provide retention and resistance form for the restoration. The use of ferrule as a part of the artificial crown was proposed in reinforcing the root-filled teeth. The purpose of this study was to investigate the effect of the ferrule height on stresses induced in an endodontically treated maxillary central incisor, which was restored with pressed ceramics, using numerical analysis. The study was developed for in order to obtain 3D models, for the design of the prepared teeth, pressed ceramics post and core systems and crowns. The use of ferrule as a part of the core was proposed in reinforcing and therefore six levels of the ferrule height were designed in order to be investigated. The study was performed on a central upper incisor, using a finite element analysis. Von Mises equivalent stresses were calculated and their distribution was plotted graphically. Regarding stress distribution in the crown high stresses are present cervical. In the prepared root stresses are under the finishing line and in the post cervical. In the post, with the increase of the ferrule height, the stresses move in coronal direction. No significant differences were found between the maximal stress values for the studied preparation designs (a ferrule height between 1 and 6mm).

Introduction: Endodontically Treated Teeth (ETT) are most likely to get fractured, if it is left unrestored compared with the vital teeth due to the loss of tooth structure and reduced modulus of elasticity. Aim: To gain insight into the rationale for choice of endodontic posts and the different endodontic post systems currently used by dental practitioners in western region of Saudi Arabia. Materials and Methods: For this survey-based study, a questionnaire was designed consisting of eight questions to assess the details of why, when and how general practitioners restore ETT and to determine contemporary use of endodontic post from 1st of November 2018 till the end of January 2019. This questionnaire was sent online to 250 private dental practitioners in western region of Saudi Arabia, out of which 202 participants responded. Data was entered in the excel sheet. Descriptive statistics like frequency and proportion was calculated for qualitative data. Results: This study included 202 participants with the mean age group of 25-50 years, out of which 108 (53.4%) male participants and 94 (46.5%) female participants. 120 (59%) of the study sample were general practitioners and 82 (41%) of them were specialists. A total of 60 (29.70) of the study sample were into general practice, reported restoring ETT with post and core followed by the crown, whereas, 30 (14.85%) of them did the crown without post, 15 (7.42%) of them completed restoration with composite and 15 (7.42%) of them did build-up with post and core. An 82 (40.59%) of the study sample who were specialists, reported restoring ETT with post and core build-up and then proceed with crowns. An 80 (39.60%) of the study sample were into general practice, reported using prefabricated fiber post whereas, 23 (11.38%) of them using cast post and 17(8.41%) of them using prefabricated metal posts. 72 (35.64%) of the study sample were specialists reported using prefabricated fiber posts and 10 (4.95%) of them used cast metal post. Conclusion: Based on the results of the study, it can be concluded that majority of the participants practiced reinforcement of ETT by using fiber posts with resin cements followed by crowns.

Abstract Aim The purpose of this study was to compare the fracture resistance of endodontically treated teeth restored with different post and core systems in combination with complete metal crowns in teeth with no coronal structure. Methods and Materials Fifty extracted mandibular premolars were divided into five groups. The coronal portion of each tooth was removed at the cementoenamel junction (CEJ) in all groups except Group 1. In this group the teeth were sectioned 1 mm above the CEJ to create a ferrule. After root canal preparations, cast posts were placed in the first four groups. Prefabricated glass fiber posts and composite cores were placed in the fifth group. An opaque porcelain layer was applied to the metal post surfaces in the third group and an alloy primer was applied to the posts in the fourth group before using Panavia F2 resin cement. No bonding agent or surface treatments were used for the first and second groups. A Ni-Cr full cast crown for each sample was prepared and cemented. A compressive load was applied at an angle of 45 degrees to the crown with a universal testing machine. After 500,000 mechanical cycles at 1.5Hz, the maximum load at fracture (N) was recorded. Results Significantly higher fracture resistance values (216.87 N) and survival rates (75%) were demonstrated for non-ferrule teeth restored with opaque layered posts than for other non-ferrule groups. The prefabricated post group showed the most favorable fracture pattern in all test groups (P=0.04). Conclusion Either a ferrule preparation or bonding with the use of an opaque porcelain layer can increase the fracture resistance of teeth with little remaining tooth structure that are restored with cast crowns following endodontic therapy. Clinical Significance Bonding cast posts to the tooth structure has a significant effect on compensating for the lack of a ferrule on endodontically treated teeth.

Endodontically treated teeth with excessive loss of tooth structure would require to be restored with post and core to enhance the strength and durability of the tooth and to achieve retention for the restoration. The non-metallic posts have of a superior esthetic quality. Various core materials can be used to build-up cores on the posts placed in endodontically treated teeth. The core materials would show variation in their bonding with the non-metallic posts and the remaining tooth structure. They will also have an effect on the strength and resistance to fracture of the remaining tooth structure. Aims: The aim of the study was to assess the fracture resistance of three composite resin core build-up materials on three prefabricated non-metallic posts, cemented in extracted endodontically treated teeth. Material and methods: Forty five freshly extracted maxillary central incisors of approximately of the same size and shape were selected for the study. Student’s unpaired ‘t’ test was also used to analyse and compare each group with the other groups individually, and decide whether their comparisons were statistically significant. Results: Luxacore showed the highest fracture resistance among the three core build-up materials with all the three posts systems. Ti-core had intermediate values of fracture resistance and Lumiglass had least values of fracture resistance.

Viable Treatment

In restorative dentistry, restoring poorly fractured endodontically treated teeth is a typical challenge. Such teeth frequently require additional root canal support in the form of a post and core repair. When endodontically treated teeth with lost coronal tooth structure are left untreated for an extended length of time, they may experience supra eruption, drifting, tilting, and rotation of adjacent teeth. Because of the lack of interocclusal space, the dentist may find it difficult to fabricate a crown. To restore normal anatomy, function, and aesthetics, teeth with less remaining crown height should have a post and core followed by a crown. The most challenging patients to treat are those with little inter occlusal clearance and steep incisal guidance. Teeth that have been badly damaged and have little or no crown structure require further retention and support. The Richmond crown is a wonderful option for restoring such teeth. For such circumstances, the Richmond crown is a viable treatment alternative that may be executed with very little incisal clearance to accommodate post, core, and crown thickness. Richmond crown, which comprised a threaded tube in the canal and a screw-retained crown, was first presented in 1878. It was eventually reconfigured as a one-piece dowel and crown when the threaded tube was removed. The current article focuses on Richmond crown restoration and its variations, including diagnosis and treatment planning for such restorations, as well as fabrication techniques.

With increased dental awareness, there has been a growing trend in patients who are opting for teeth retention, so post-endodontic restorations play a significant role in dictating restoration longevity. However, till date restoration of root canal treated teeth is still controversial. Root canal treated teeth often suffer from extensive loss of tooth structure because of access cavity preparation, caries removal, replacement of restoration and trauma.1 Traditionally the restorative material of choice for an endodontically treated molar would be post and core followed by metal / ceramic crowns. However, studies have shown that these intra-canal posts may increase risk, of undermining the residual tooth structure, root perforation and catastrophic failures.2 With adhesive strategies, there has been a paradigm shift towards post-less restorations and utilisation of pulp chamber as an extension, thus integrating the crown and core as a single unit or monobloc. 2,3 This was the concept of the endocrown technique. 3 Bindle and Mormann first, delineated the use of porcelain adhesive endodontic crowns.4 Endocrowns are more practical, conservative, aesthetic, simple to fabricate, economical, less time consuming and allows favourable distribution of masticatory stresses. Most studies on endocrowns showed comparable or somewhat superior results to other conventional treatments for endodontically treated teeth (ETT). However, the available literature is based largely on the use of ceramic endocrowns. 2-4 It was observed that data pertaining to endocrown fabrication with other indirect restorative materials is still limited, and the choice is still unclear.Indirect composites show enhanced mechanical properties, creation of ideal contacts and contours, favourable wear, aesthetics and can serve as an economical alternative to ceramics.5 Hence, this paper attempts to present a case report of functional and aesthetic rehabilitation of an endodontically treated molar with an endocrown restoration utilising indirect composite (SR Adoro System).

Summary: Restoration of the endodonticallytreated teeth is a controversial topic in restorative dentistry, since many options exist to restorewhole or partially dental crowns. The option for treatment is not selected based on a precisediagnosis of the state of the dental remanent and differences between anterior and posterior teethare not evaluated. Therefore, a classification of the extension defects of endodontically posteriorteeth (EPT) is presented. This classification is based on 4 specific variables: vertical height andwalls distribution of supragingival remaining coronal tooth structure or core, diameter and rootcanal depth, and the distance of floor pulpar chamber and the root furcation. The correctapplication of this classification can help the operator to choose the best treatment option for thereconstruction of EPT, also this classification can help investigators to reach more organizedresults in future investigations on the reconstruction of EPT. Key words: Post and core. Endodontic.Diagnostic characteristics.
