A Comparative Study of Success Rates of Post and Core Treated Anterior and Posterior Teeth Using Cast Metal Posts.

Post and core restorations are performed (generally after treating the root canals of the tooth) when the majority of the tooth structure has been rendered ineffective to support itself/the crown of the tooth. In this clinical study, we aim to compare the difference between post and core treatment of anterior and posterior teeth and their success/failure rates. Our investigation aimed to compare the clinical survival rates of custom-fabricated cast metal post-and-cores in cases of anterior and posterior teeth while controlling for the population's age and gender, type of post material, length of the post, amount of alveolar bone tissue supporting the roots, tooth location in the dental arch, and type of cement used, as well as the effect of opposing dentition and the type of definitive prosthetic treatment received. 112 individuals who had received root canal therapy (RCT) and were chosen to receive post and core therapy following their RCT were chosen for the study, and a total of 164 teeth were scheduled to undergo the therapy. All the posts used were made of cast metal, and the patients were divided into two groups: 48 individuals had the posts placed in their posterior teeth (a total of 71 teeth in this case), and the second group was made up of the remaining 64 patients, all with 93 teeth in the anterior region. The follow-up was done twice at a six-month interval after cementation was complete. No significant changes were observed between the stability of the post structures in the anterior and posterior teeth that were examined, and the survival rates were found to be similar in both instances. The cast metal posts performed at a similar success rate for the one-year period when the teeth were under our observation, and there were no considerable changes seen statistically. But it must be mentioned that a short follow-up period was observed, so the results might probably see some variations when a longer period of time is taken into consideration.

Probability of survival and failure mode of endodontically treated incisors without ferrule restored with CAD/CAM fiber-reinforced composite (FRC) post-cores

PurposeThis study evaluated the probability of survival and failure mode of endodontically treated incisors without ferrule restored with CAD/CAM FRC post-cores. MethodsRoot canals of bovine incisors were treated, leaving post preparations of ∼10 mm. Teeth were allocated into three groups: (i) cast metal post-core, (ii) FRC prefabricated post with a direct resin core build-up, and (iii) CAD/CAM FRC post-core. Posts and zirconia crowns were cemented using resin cement. Specimens were subjected to step-stress accelerated-life fatigue testing in water. Use level probability Weibull curves, probability of survival for a mission of 100,000 cycles at 25, 50, and 100 N, Weibull modulus, and characteristic strength were calculated and plotted. Failure mode was examined under a stereomicroscope. ResultsRestored incisors demonstrated high probability of survival (93–100%) for missions estimated at 25 and 50 N, irrespective of post-core foundation. At 100 N, incisors restored with metal posts presented significantly higher probability of survival (99%) relative to CAD/CAM posts (79%), whereas FRC groups demonstrated no significant difference. Weibull analysis indicated no significant difference on the Weibull modulus (m = 3.38–5.92). Incisors reconstructed with metal post-cores (431 N) presented significantly higher characteristic strength relative to prefabricated (200 N) and CAD/CAM (202 N) FRC post-cores. While post fracture was the chief failure mode for prefabricated and CAD/CAM FRC post-cores, post and/or root fracture were the main event for metal post-cores. ConclusionEndodontically treated incisors without ferrule restored with CAD/CAM FRC post-cores presented promising probability of survival for loads compatible with anterior masticatory forces and favorable failure modes.

A study to evaluate the preferences of dentists for the materials chosen to restore endodontically treated teeth and the influence of both clinical experience and level of specialization on the dentist's choice of posts

Background: In endodontics, dentist's choice for using posts/materials relevant to posts used to restore endodontic-treated teeth is influenced by clinical experience, whether concerning the length of practice time and level of specialization. Objective: Traditional restorative approaches are being modified as newer materials become available and patient preferences shift. The purpose of the study was to see if dentists' preferences for using posts and other materials associated to post used to restore endodontically treated teeth are influenced by practical experience, whether measured by the length of clinical practice time or level of specialty. Methodology: A cross-sectional study was conducted with dentists (n = 100) working in Karnataka utilizing a questionnaire. Data on sociodemographics, clinical experience, postgraduate training, and postendodontic restoration characteristics (posts/types of cement and rubber dam application) were obtained. The samples only included general and specialist dentists. A descriptive analysis was performed on the data. The Chi-square test and Fisher's exact test investigated the relationships. Results: The most chosen materials were metal posts (60%) and resin cement (70%). There was a statistically significant association between clinical practice duration and postuse type (P = 0.017). In addition, there was a highly significant relationship (P = 0.001) between clinical practice time, level of specialty, and the use of rubber dams. Conclusions: Dentists favored metal posts for post endodontic restorations, while resin-based cement was the preferred luting cement for the posts' cementation. Additional training and more clinical practice time were factors in several dental postselection decisions.

A Design Method for a Leaky-Wave System With Uniform Field Coverage and Broadside Radiation for a Vacuum-Tube Ultra-High-Speed Train

The communication system for vacuum-tube ultrahigh-speed trains faces great challenges from unstable signal coverage and severe Doppler effects as a result of long running distances and ultrahigh speeds. This communication presents a possible solution for a communication system in a vacuum-tube high-speed train system that operates using a leaky waveguide. The design method for the leaky waveguide is demonstrated in detail. The developed leaky waveguide consists of periodic metal posts and longitudinal slots in a staggered arrangement, and it can achieve the properties of uniform field coverage and broadside radiation. Therefore, the performance of long-distance transmission with stable signal quality can be realized, and the Doppler effect in the scenario of ultrahigh-speed rail can be mitigated. Leaky waveguides with lengths of 5, 10, and 20 m are designed as verifications of the method. A 5 m leaky waveguide is fabricated and measured. The measured results are consistent with the simulated results, demonstrating that a uniform field distribution and broadside radiation can be achieved using the developed leaky waveguide.

Push-Out Bond Strength of Endodontic Posts Cemented to Extracted Teeth: An In-Vitro Evaluation.

(1) Background: An ideal bond strength between endodontic posts and root canal dentin is essential for optimal retention and good prognosis. This study aimed to evaluate the push-out bond strength (PBS) of prefabricated fiber and metal posts, luted with resin cement to natural dentin. (2) Methods: Extracted premolars with similar root dimensions were assigned into two groups of 30 each for the metal and fiber posts. Teeth were mounted in acrylic blocks exposing 2 mm of the coronal root. Teeth were subjected to endodontic treatment and post-space preparations. Two groups were further subdivided into three sub-groups (n = 10) according to the size of the posts (# 4, 5 and 6). Posts were cemented with resin cement. Specimens were sectioned into 4 mm slices and subjected to the PBS test. (3) Results: The mean PBS was similar for the metal and fiber posts bonded with resin cement, showing a statistically significant result. An increase in post size increased the bond strength initially, but a further increase in size did not show any marked difference. A total of 71.66% of tested specimens failed with the adhesive failure mode. (4) Conclusions: Metal posts showed slightly higher retention compared to the fiber posts, although the p-value was similar for both types. An increase in the size of posts showed increased retention. The most common mode of failure was adhesive failure between cement and dentin.

An In Vitro Study Comparing the Diametral Tensile Strength of Composite Core Build-Up Material With Three Different Prefabricated Post Systems.

Statement of problemDental restorations are subjected to tensile stresses from oblique or transverse loading of their complex geometric forms, making tensile strength a fundamental mechanical property. Since composite core build-up materials are brittle, the integrity of the post and core depends on their tensile strength and resistance to fracture when utilized with various prefabricated post systems. Therefore, it is essential to determine the tensile strength of the prefabricated metallic and nonmetallic posts used to reinforce the composite resin core.PurposeThis study compared the diametral tensile strength (DTS) of three prefabricated post systems with composite core build-up material.Material and methodologyTen composite resin cores from four different groups were formed. The control group was the composite resin core without a post (group 1). Group 2 was composed of composites with metal posts, group 3 was composed of composites with glass fiber posts, and group 4 was composed of composites with carbon fiber posts. All the samples were kept in a humid place for seven days to mimic the conditions in the mouth. DTS was determined by recording the tensile force required to fracture the core material by performing a diametral compression test for tension after a week. The observations were analyzed using a one-way analysis of variance (ANOVA), followed by a post-hoc test.ResultsThe tensile strength of the resin core material was decreased by 28.1%, 20.8%, and 10.4% by using posts made of stainless steel, carbon fiber, and glass fiber, respectively. Among the three post systems, stainless steel had the lowest mean DTS values, while glass fiber had the highest mean DTS values.ConclusionComposite core glass fiber post systems showed higher tensile strength than other post systems.

Aesthetic post materials for restoration of endodontically treated teeth-A review

Posts are fabricated for the purpose of retaining the restoration in cases where the coronal structure is inadequate. They strengthen the endodontically treated teeth. Metallic posts being rigid compared to the tooth structure limits its use. Post and core systems available nowadays permits the restoration of endodontically treated teeth aethetically. Features like light transmission, biocompatibility are improved with the metal free posts unlike metal posts To improve aesthetics, physical properties, biocompatibility, various aesthetic posts have been introduced and is also available in the market.

Finite Element Study of PEEK Materials Applied in Post-Retained Restorations.

Background: This study aimed to investigate the biomechanical behaviors of polyether ether ketone (PEEK) and traditional materials (titanium and fiber) when used to restore tooth defects in the form of prefabricated post or customized post via computational modelling. Methods: First, the prototype of natural tooth, and the prototypes of prefabricated post and customized post were established, respectively, whilst the residual root was restored with dentin ferrule using reverse engineering methods. Then, the stress and strain of CFR-PEEK (PEEK reinforced by 30% carbon fiber) and pure PEEK (PEEK without any reprocessing) post were compared with those made in traditional materials using the three-dimensional finite element method. Results: From the stress point of view, compared with metal and fiber posts, CFR-PEEK and pure PEEK prefabricated post both demonstrated reduced post-core interface stress, post stress, post-root cement stress and root cement stress; moreover, CFR-PEEK and pure PEEK customized post demonstrated reduced post stress, post-root cement stress and root cement stress, while the strain of CFR-PEEK post was the closest to that of dentin. Conclusions: Compared with the traditional posts, both the CFR-PEEK and pure PEEK posts could reduce the risk of debonding and vertical root fracture, whether they were used as prefabricated posts or customized posts, but the biomechanical behavior of carbon fiber-reinforced CFR-PEEK restorations was the closest to dentin, no matter if they were used as prefabricated post or customized post. Therefore, the CFR-PEEK post could be more suitable to restore massive tooth defects. Pure PEEK needs filler reinforcement to be used for post-retained restoration.

Post Placement and Restoration of Endodontically Treated Canines: A Finite Element Analysis Study

The purpose of this study was to show the improved outcomes of restoring endodontically treated teeth with fiberglass posts compared to restorations using metal posts. In our study, we used the Finite Element Method (FEM), which is based on the principle that a physical model that supports a given load distributes the stress throughout its volume. We sought to assess what stress results in a tooth when it is restored using a fiberglass post compared to restoration using a metal post. The finite element analysis showed that a system consisting of a tooth with a fiberglass post is more stable in terms of the maximum stress than a system consisting of a tooth with a metal post. The maximum displacements and deformations were obtained in the case of a canine restored with a fiberglass post, which showed that this system had a high elasticity, therefore, higher strength than a canine restored with a metal post, which had high rigidity.

Push-out Evaluation on Metal and Fiber Posts Using Two Different Types of Cement in a Hyper-Narrow Environment

Abstract Objective Some teeth will be damaged due to caries, trauma, or previous improvement; posts are used to repair them. Underwater divers suffer from barodontalgia as a result of the tremendous amount of pressure they feel when diving. Meanwhile, barodontalgia instances involve teeth with defective restorations. Therefore, this study aimed to determine the push-out bond strength on metal and fiber posts using two different types of cement in a hyper-narrow environment. Materials and methods In this study, 96 single-rooted teeth, including central and lateral maxillary teeth and mandibular premolars were provided and underwent endodontic treatment. Root canal treatment, including cleaning the root canal using the manual and rotary files was performed in f2 size with 6% tipper. For purification, washing was performed in two steps with 5.25% sodium hypochlorite and normal saline, respectively. The obtained data were evaluated using statistical methods such as one-way analysis of variance and the Levene and Tamhane additional tests. Results The quantity of push-out strength was dramatically reduced in the metal posts and fibers groups due to increasing ambient pressure. The highest decrease rate was observed in the group of metal posts and resin cement. The highest bond strength in a typical environment was related to fiber posts, and among the fiber groups, those that had the highest bond strength were used as a combination of resin cement and fiber posts. Conclusion The highest level of bond strength among the study groups, at standard pressure and in a hyper-narrow environment, was related to fiber posts and resin cement. Therefore, the best choice for treatments for divers in a hyper-narrow climate is a combination of fiber posts and resin cement.

Ultra-Thin Artificial Magnetic Conductor for Gain Enhancement of Antenna-on-Chip

System-on-chip (SoC) has become an attractive solution to achieve highly integrated wireless systems. However, the antenna-on-chip (AoC) suffers from poor radiation due to the lossy silicon substrate in standard complementary metal–oxide–semiconductor (CMOS) processes. Artificial magnetic conductors (AMCs) with the ground plane above the silicon can enhance the radiation; however, fitting the AMC completely in the thin stack-up (~10–15 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> ) is extremely challenging, particularly for frequencies below 100 GHz. In this article, metallic posts (MPs) and embedded guiding structures (EGSs) have been investigated to reduce the AMC thickness by employing the available vias and metal layers in the stack-up. An in-house CMOS-compatible process has been used to realize the AoC, where typical low-conductivity adhesion layers have been avoided to reduce the undesired losses by using the surface roughness in a unique fashion. With MP and EGS approaches, AMC thickness can be reduced by 33% and 41%, respectively. The AMC with EGS fits within an oxide of a thickness of 16 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> . A monopole antenna, backed by this AMC, demonstrates a gain of 5.85 dBi and a radiation efficiency of 57% at 94 GHz, bettering the gain and radiation efficiency by 9.15 dB and 42%, respectively, compared to the case without AMC.

Clinical approaches and removal of cast metallic posts for their replacement by the fiberglass posts: a concise systematic review

Introduction: A successful placement of an intraradicular post needs a good endodontic treatment. Consideration should also be given to the possibility of its future removal. Authors have shown that approximately 10% of cases of teeth indicated for endodontic retreatment require removal of intraradicular posts. Objective: To carry out a concise systematic review to analyze the reasons for replacing intraradicular posts, the most effective and used techniques for removing the metallic post, the manufacture of the fiberglass post, and the difference between the two types of posts. Methods: The present study followed a systematic review model, following the rules of systematic review – PRISMA. The search strategy was performed in the PubMed, Cochrane Library, Web of Science and Scopus, and Google Scholar databases. Results and Conclusion: A total of 112 articles were found. A total of 56 articles were fully evaluated and 18 were included in this study. Based on the objective and results found in the present study, the review demonstrated the main advantages and disadvantages of the clinical performance of cast metal posts and fiberglass posts, as well as the reason for switching from metal to fiberglass posts. Despite the wear caused by endodontic treatment, it is important to check the remaining dentin to choose the best retainer, observing the amount of this remaining structure, as it directly influences the selection of the post. Regarding the removal of the metallic pin, wear, ultrasound, and seizure/removal with some traction device are used. The replacement of the metallic post can opt for fiberglass posts because they have a greater advantage compared to the metallic post, mainly for aesthetics, the manufacturing technique is more agile, they do not generate risks of root fracture and if, for any eventuality, it needs to be removed. to portray the channel, the technique is smooth and easy.

Should a metal post always be replaced before a new indirect -restoration?

Before realizing a new indirect restoration on an endodontically treated tooth, present restorations and possible posts need to be assessed. In the case of a metal post, the mismatch in flexural modulus between the dentine and the post might increase the risk of a vertical root fracture. Is it therefore prudent to replace such a metal post, before the fabrication of a new indirect restoration? Two scenarios might be considered to answer this question. First, would a glass fibre post result in a lower risk of failure? Two systematic reviews of the literature comparing glass fibre and metal posts for the short term were contradictory. Second, is the occurrence of a vertical root fracture associated with the presence of a post? Such association could not be established either. On the basis of the current literature, there does not appear to be evidence to support actively replacing a metal post.

Design of compact dual‐band substrate integrated waveguide filtenna

AbstractA compact dual‐band substrate integrated waveguide (SIW) filtenna is presented. A dual‐mode SIW cavity, resonating at its fundamental mode TE110 and high‐order mode TE120, which respectively dominate the lower and upper passbands, is employed as the feeding cavity. After that, a slot‐loaded SIW cavity, performing as two half‐mode radiating cavities, is perpendicularly arranged over the feeding cavity for the purpose of expanding the operational bandwidth and also strengthening the filtering response. Furthermore, two metal posts are utilized to independently regulate the coupling strength of magnetoelectric energy of the two passbands, respectively. A prototype of this dual‐band SIW filtenna is designed, fabricated, and tested for validation. The measured results agree well with the simulated values, demonstrating that the maximum realized gains are 4.9 and 5.38 dBi, and the impedance bandwidths are 2.1% (2.792–2.852 GHz) and 4.1% (3.992–4.16 GHz) for lower and upper passbands, respectively.

A Transmission Zero Position Control for 28 GHz Rectangular Waveguide Cavity Bandpass Filter

This paper presents a method to control on single real-frequency transmission zeros (TZs) position in the reject band for third-order waveguide band pass filter (BPF). The external couplings are achieved by using a coaxial probes while the internal couplings are achieved by using short-circuit metallic posts. The TZs appear are generated by forming a triplet, i.e., multipath cancellation between non-adjacent resonators. The dimensions of the metal post between non-adjacent resonators are adjusted to control the position of TZs in the rejection band. A third order waveguide generalized Chebyshev BPF is simulated with HFSS at a center frequency of 28 GHz to validate the design method. The simulated insertion loss is 0.05 dB and the bandwidth (BW) is 500MHz. The simulation demonstrates the compatibility of the presented filtering structure with 5G applications.

Wonder Woman

Wonder Woman Constance Adler (bio) There is a scar in the center of my chest. A whitish and shiny round patch, the size of a silver dollar, the scar does not match the surrounding skin. It does not blend with its environment; it cannot not hide. Located just above what we might generously refer to as my "cleavage," this scar marks the place where a hard pad pressed into my skin for the months that I wore a back brace, known as the Milwaukee brace, when I was fourteen years old. Here is a picture of the brace: Imagine a contraption that clasped my head in a metal loop, secured tight against my chin and the back of my skull. Metal posts connected the head restraint to a hard, plastic girdle that encased my pelvis and was locked shut at the back with straps, so tight that it left deep-red indentations in the soft flesh of my backside. Once in place, the whole thing resembled a medieval instrument of torture. I came to think of it as a cage that I carried around with me all the time. It was hideous, and it made me hideous. While I was in the brace, it was impossible for me to move from hips to head. The cage held me in a rock-rigid grasp. I could not sleep curled up in a protective knot, as was my habit, but had to lie on my back like a corpse on a slab. I could not bend or turn side to side or look up or down. I could walk, but it was difficult to eat or talk because my chin kept hitting the metal loop around my head when I opened my mouth. I could not tip [End Page 111] my head to look down to the food on the plate in front of me and had to guess at what I might be forking into my mouth. I could go to school, and spend time with my friends, but I was always caged. I had to wear extra-large clothes to fit over the brace, and its hard unsightly lumps protruded through my clothes instead of the normal soft form of my girl's body. I could not see my own feet or reach down to tie my own shoelaces. If my shoe came untied at school, I had to ask a friend to tie it for me. Some kids asked if I'd been mangled in a car accident. The clinical purpose of the Milwaukee brace was to maintain my girl's body in this unyielding position for a year until my back and shoulders grew accustomed to a center plumb line. Then I'd be released, ideally as a more perfect girl. One day I'll have to find out why Milwaukee gets credit for this instrument of torture. What I can tell you now is that my parents put me into this brace for reasons that were a complete mystery to me. They had threatened me with a back brace if I didn't stand up straight, a threat that I did not take seriously. At the dinner table, my father enforced the posture requirement by hitting the back of my head. Slouching made me ugly, apparently, or less than perfect, which for a girl was a moral stain. But I wasn't paying much attention to threats or perfection. I was a dreamy, distracted child with other things on my mind, far more interesting than my posture. This private realm of my imagination also offered an escape from beatings, so I went there often. When I failed to be mindful of my posture, my parents followed through on the threat. My mother and father presented this back brace to me as a punishment for my willful disobedience. This sounds crazy, I know. Why would anyone do that to their kid just to win a power game? But that was thrust of their argument at the time. My mother was in charge of bringing me to the DuPont Orthopedic Clinic in Delaware. During the course of fitting me for the brace, one of the doctors took photographs of...

An Umbrella Review of Systematic Reviews and Meta-Analyses Evaluating the Success Rate of Prosthetic Restorations on Endodontically Treated Teeth.

Materials and Methods The electronic search was conducted in the MEDLINE/PubMed, Cochrane, and Google Scholar databases until November 2020, regardless of language limitations. The inclusion criterion was as follows: S/M-R regarding prosthetic restorations in endodontically treated teeth. Three qualified researchers evaluated the inclusion criteria and bias risk. The fourth investigator was referred to when facing any doubtfulness. Results From 43 achieved S/M-R, 14 studies were selected for this inquiry. Primary extracted information included success rate, survival rate, and postendodontic failure rate. Five S/M-R had a moderate risk of bias, and nine S/M-R had a low risk of bias and were considered strong clinical evidence in this examination. According to the low-risk reports, the success rate of fiber posts was higher than that of metal posts; the rate of root fracture in metallic and fiber posts was alike; the failure rate for fiber posts was comparable to fixed partial dentures or single crowns; the construction of endocrowns was likely to perform better than intracanal posts, composite resin, or inlay/onlay restorations. Conclusion It appears that with practice and experience, deciding which type of restoration to choose changes. In dental restorations associated with root canal therapy, the single crowns are likely to be a proper option. Nevertheless, due to the heterogeneity of the studies, more clinical assessments are required to achieve more specific findings in this field.

Fracture Resistance and Stress Distribution Pattern of Different Posts-Core Systems in Immature Teeth: An In Vitro Study and 3D Finite Element Analysis.

Introduction Restoration of immature teeth with open apices and thin dentinal walls with conventional post systems remains a challenge. The purpose of this study was to evaluate the fracture resistance of simulated immature teeth restored with different intraradicular posts and assess their stress distribution pattern using 3D Finite Element Analysis (FEA). Methods Fracture strength testing using universal testing machine was carried out in simulated immature teeth restored with different intraradicular posts grouped as follows: Group A: teeth not restored with posts served as control group; Group B: Cast metal post (CMP); Group C: Customized Composite Post (CCP); Group D: Fiber post (FP). Four 3D FEA models of the above groups were created using CATIATM software and analyzed for stress distribution using ANSYSTM. The results of fracture strength testing and FEA were correlated. Multiple group comparisons were analyzed by one-way ANOVA followed by Tukey HSD post hoc test. Results The CMP exhibited highest fracture resistance (336.43 N) but resulted in root fractures. The CCP exhibited lower fracture resistance (240.90 N) and favorable stress distribution as compared to CMP. The FP and control group exhibited lower fracture resistance values of 182.69 N and 130.46 N, respectively. The results of 3D FEA demonstrated higher stress concentration in model comprising metallic post and core. Conclusions Teeth restored with cast metal posts and cores exhibited maximum fracture resistance followed by the customized composite posts, the fiber posts, and the control group. The cast metal posts indicated higher von Mises stresses concentrated in the radicular region; however, the customized composite posts, the fiber posts, and the control group demonstrated stress concentration in the coronal region.
