The Aesthetic

Endodontically treated teeth (ETT) have been problematic in most cases as a result of dental caries, fractures, previous restorations and endodontic procedures. Several post system techniques and materials are currently used to build up ETT with moderate or severe loss of coronal tooth structure and to retain final restorations. Following root filling, the custom-made cast metallic post and core with metal-ceramic crowns was the traditional restoration of choice, but this has changed. The patients’ primary motivation for seeking superior dental aesthetics, particularly in the anterior aesthetic zone, has prompted the development of non-metallic restorations. Several new types of polymeric and more aesthetic quartz and glass-fibres posts, combined with direct resin composite cores, provide an aesthetic foundation for an all-ceramic crown and have overcome the aesthetic limitations of metallic posts and cores in the anterior teeth. Until recently, there has been controversy in the dental community regarding which material or technique is the most favourable for the restoration of ETT. It seems that the amount and retentive capacity of the remaining tooth structure, the position of the tooth in the dental arch, the functional or para-functional loading on the tooth, and the treatment plan to restore aesthetics and function all influence the selection of the most appropriate post system for each case.  Hence the present study was planned for Evaluation of Different Types of Crowns Used For Restoration Of Endodontically Treated Teeth. The present study was planned in Department of Conservative Dentistry and Endodontics, Buddha Institute of Dental Science and Hospital, Patna, Bihar, India. The 40 cases of maxillary anterior endodontically treated teeth (ETT). The roots were restored with reinforced GFPs (Relaxy Fiber Post, 3M ESPE, Germany), and composite resin cores (Tertic-N-Ceramic, Ivoclar Vivadent, Lichenestine). The survival of ETT is contingent on the residual sound tooth structure that remains after the endodontic access and caries removal are performed consequently the most important factors upon restoring ETT become the maximum preservation and conservation of enamel, dentin and the dentinoenamel junction. Hence, bonded partial restorations are always preferred over full coverage cementable crowns. More clinical studies comparing adhesive crowns bonded to postless build-ups or post and -core build-ups are needed for a better understanding of postless approaches in biomimetic restorative dentistry.

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: The aesthetic rehabilitation of endodontically treated teeth depends on the degree of destruction of the crown, the tooth in question, the bone support, the type of prosthesis and the types of forces to which these teeth will be submitted. The indirect composite resins have improved physical and mechanical properties thanks to the incorporation of inorganic components and multifunctional monomers with a greater number of bonding points, making them capable of solving the problems in which ceramic restorations would be indicated. Objective: To present a clinical case report of an aesthetic rehabilitation of anterior teeth with indirect composite resin as a viable and less expensive treatment alternative. Case Report: Upon clinical examination, extensive and deficient restorations were observed in the upper anterior teeth. The proposed treatment plan aesthetic rehabilitation of dental elements with ceromeres. Conclusions: This treatment represented a viable and less expensive option that can be used both in situations of great dental destruction and in small dental absences, in substitution for ceramic restorations.

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

ABSTRACT Loss of tooth structure occurs due to caries, endodontic treatment, or fracture caused by trauma; restoring these teeth is difficult task for a clinician. Post and core is an option for teeth when excessive tooth structure is lost and teeth need to be restored with crown and bridge procedure. They can be prefabricated post with composite built up or a one-piece custom-made post. The custom-made cast metal post and core have disadvantage due to their color that imparts grayish hue to overlying ceramic restorations. Masking the metal core can enhance the esthetic of all ceramic restorations that are placed over the cast post and core. A case report is being presented where the metallic core was masked with ceramic built up on labial surface of metal core. How to cite this article Shah NP, Gaikwad AM, Ram SM, Nadgere JB.

Abstract Background: Providing restorations to anterior teeth in children is a challenging task due to the need for high esthetics, strength, and durability. This study was done to compare prefabricated primary zirconia with resin composite strip crowns on primary maxillary central and lateral incisors with regards to gingival health, plaque accumulation, recurrent caries, restoration failure, and opposing teeth wear over a period of 3, 6 and 12 months. Methods: Children attending the King Abdulaziz University, Faculty of Dentistry (KAUFD) clinics who needed restorations were screened for inclusion criteria. A total of 120 teeth were treated; 60 with zirconia and 60 with strip crowns. Randomization was done by simple random allocation using SPSS software version 20.0 (Armonk, NY; IBM Corp.). A simple descriptive statistic was used for analysis by Wilcoxon Signed-Rank test and Chi-square test. Level of significance was set at (α = 0.05) and level of confidence at (95%). The presented research was registered retrospectively at ClinicalTrials.gov in 6th of August 2017, under registration number NCT03184012.Results: Zirconia crowns showed significantly less gingival bleeding at the 3- and 6-months follow up periods (p<0.006, p<0.001; respectively), less plaque accumulation at all follow up visits (p<0.001), no restoration failure (p<0.001), but more wear to opposing teeth (p<0.02). No significant difference was found between the two crowns with regards to recurrent caries (p<0.135).Conclusion: Based on our data we conclude that overtime teeth covered with zirconia crowns show better gingival health and less bleeding, plaque accumulation as well as less loss of material. On the other hand, zirconia can cause more loss of opposing tooth structure.

The Impact

The aesthetic treatment for anterior teeth requires a series of clinical and technical evaluations to obtain a predictable result, following a well-defined operating sequence. Today, the clinical–technical team can use different digital tools in the different steps of the workflow. A preventive assessment, the knowledge of limits, and the possibilities of surgical and prosthetic procedures allow to use these devices. Sharing goals of the treatment with the patient according to their expectations and needs is the key point of the treatment plan. Setting a defined treatment plan avoids invasive procedures. In this clinical case report, a 27-year-old patient affected by Class II div 2 malocclusion with deep bite was treated with a full digital workflow. Previewing the aesthetics was through dedicated software, which shows operators and patients the objectives of the therapy and guides the dental technician in the first phase of the work. The use of digital flows in the prosthetic phases reduces the working time. In this case, it shows the impact of a digital workflow on peri-prosthetic therapy for the aesthetic rehabilitation of the upper central incisors in a young adult.

Statement of the problem: restoring endodontically treated teeth (ETT) is one of the major treatments provided by a dentist. Glass fiber posts (GFP) showed good clinical performance during last few years.Aim of the study; to assess and compare the clinical as well as the radiographic performance of different types of ceramic crown systems used in restoration of maxillary anterior teeth over a cemented GFP and composite resin core.Materials and methods: 50 ETT with GFP were included in this study. These teeth were divided into four gropes (composite resin. Porcelain fused to metal (PFM), e. max and zirconia restorations). Both the clinical and radiographic assessments were done for the restoration at a period of one week, 3, 6, 9, and 12 months after composite build up and crown's cementations. All data were registered and analyzed by SPSS program using percentages and Kaplan-Meyer analysis. Fisher’s exact test was used for categorical values while log-rank test was used for descriptive statistical analysis.Results: the clinical assessment showed no changes in the one week, 3 and 6 months in the four groups. While during the 9 and 12 months, a movement of the crown margin under finger pressure was present in one case, loss or retention in 2 cases of zirconia, the periodontal status with violation of biological width was present in one case of PFM and finally the color changes were obvious in one case of PFM and 2 cases of composite restoration. All the restorations in the four groups had no radiographic changes in the one week and three-month assessments. While during six-month follow-up, a loosed of retention in one case of the zirconia crown was detected. At the 9 and 12 months, two cases showed recurrent caries at the cervical margin of the composite restoration, cases with periapical infection and other with loss of retention of the post were recorded in the PFM restoration.Conclusion: e. Max and zirconia all ceramic crowns showed better clinical and radiographic performance than the PFM and composite restorations over 12 months recall.

ABSTRACT An endodontically treated anterior tooth requires extracoronal restoration when the tooth structure is weakened or lost due to caries, endodontic treatment, placement of previous restorations and/or is discolored. The reduced tooth structure makes retention of extracoronal restoration difficult. The purpose of post is to provide retention for the core restoration, which replaces lost coronal structure. This article describes restoration of mutilated maxillary central incisors by using cast post and core, followed with porcelain fused to metal restorations.

Cosmetic veneer has become a popular option for patients seeking to improve aesthetic in their smile. The procedure can be done through a direct or indirect technique which differs in term of material used and laboratory involvement. Despite producing a better aesthetic result than its direct technique counterpart, high-cost treatment, multiple visit requirement and invasive nature of tooth preparation are proven to be a stumbling block to the patient in some cases to choose indirect technique. Therefore, direct composite veneer technique can be offered due to its low costing and conservative concept which advocates more tooth structure preservation. This case report is about direct composite veneer for anterior teeth rehabilitation and its simple and conservative protocol.

Dental Injuries

Traumatic dental injuries are common clinical problems during childhood, and may have complex etiologies causing physical and physiological impairment. The aim of this study was to report the management of a severe traumatic dental injury in an 8-year-old female patient, victim of a motorcycle accident, who was taken to a pediatric dentistry clinic three months after the accident. After clinical and radiografic examination, we observed the avulsion of the permanent maxillary central incisors and of the permanent left lateral incisor, with considerable lingual interposition, interfering in speech and swallowing. The patient showed low risk of caries and good behavior during the appointments. However, she demonstrated to be embarrassed to smile. Besides the preventive treatment concerning caries, the treatment plan included immediate care and subsequent monitoring of the psychosocial reestablishment. For this purpose, an acrylic partial denture was made in order to replace the missing anterior teeth, maintaining the characteristics of the mixed dentition and preserving the aesthetics and the function. Follow-up appointments were performed one, three and six months after the first visit, aiming to monitor the adaptation of the prosthesis, as well as the growth and development of the child’s dentition. Thus, the aesthetic and functional rehabilitation was achieved regarding the patient’s satisfaction, enabling immediate social reinsertion.
