Background : Nows a days has developed many kind of dentures to improve the functionality, comfort aesthetics. Stability, retention and its aesthetic can be improved by attachments. With many kind design assortment of dentures so need a different technique with the existing design. Purpose : The aim of this study is to know the danture manufacturing process in combination with Castable protesa Extracoronal Attachments labolatory procedure. Review: Fixed dentures are each bonded teeth protesa, inserted mechanically and support by teeth or dental implant abutment or that provide the main support for the dental protesa. A partial denture is a spin-off protesa that replaces one or more missing teeth, on the maxillary or mandibullary and can be opened by patients without the supervision of a dentist. Extracoronal attachment is an attachment that is part of the male and female part are almost entirely outside the contours of the Crown of the tooth. Conclusion: the initial stages are making of coping use wax pattern and inserted the female, the casting of metal, porcelain applications, making the wax pattern of the metal frame work, the casting of metal, inserted male, making a removable dentures.

While using casts in place of original bones and teeth for study with the SEM is a rather common practice, periodic updates and introductions of unique casting methods help to keep the process of improving cast quality cumulative, limiting unnecessary repetition of ineffectual procedures. The following is a summary of casting methods that I have synthesized from several published reports as well as some that I have developed independently (e.g., Waters and Savage 1971; Scott 1982; Rose 1983; Gordon 1984; Teaford 1991; Buikstra and Ubelaker 1994; Schmidt, 1998). The study for which I first employed these methods consisted of hundreds of archeologically- derived human teeth dating from about 1,000 to around 10,000 years ago. The study required detailed views of dental surfaces magnified 500X (Figure 1). The casts that I produced routinely had features that were distinct at magnifications of 2.000X and higher.

This article presents the results of the research on the development of the technology of increasing the service life of the sheets in the working conditions of the casting at the Central Repairs and Mechanical Plant at the Almalyk Mining and Metallurgy Refinery (CPC). One of the factors that led to the loss of Val schisternia was the study of the appearance, rupture and dental breakdown of the working surfaces, which led to increased production costs. Analyzes have shown that thermal processing and so-called thermal processing are recommended to increase the working capacity of the plants and factories at the refineries of electrochemicals (EHP).

Dental diseases are among the most common ailments, and dentists in the United States spend over 50% of their time in dental practice rebuilding carious, malformed, and traumatically injured teeth. It is logical, therefore, that the majority of the dental school curriculum is devoted to the diagnosis, prevention, and treatment of teeth with anomalies. Dentists have several choices of materials they can use to accomplish the task of rebuilding teeth. Besides amalgam, they have ceramic materials, resin composites, base-metal and noble casting alloys, and glass-ionomer cements to use to restore the posterior dentition. Each of these restorative materials has advantages and disadvantages, and the clinical judgment as to when a particular material should be used is given a high priority in dental education. Amalgam is the most widely used of these restorative materials, with 92% of dentists listing it as the material of choice in the posterior of the mouth (Clinical Research Associates, 1990). Dentists have been placing amalgams for over 150 years in the US. They placed 150 million last year, which represents over 75 tons of amalgam alloy. The reasons that dentists use this restorative material so frequently are its durability, ease of manipulation, and low cost. Numerous clinical studies have been conducted on the serviceability of amalgam. Most of these have been on the old, low-copper alloys, and results indicate that they last from 8 to 15 years (Bailit et al,, 1979; Osborne et al., 1980; Qvist et al., 1986). In the past 20 years, vast improvements have been made in amalgams with the development of the high-copper systems. Clinical studies initiated in the 1970's are reporting that the well-placed high-copper amalgam will last over 30 years (Laswell et al., 1989; Letzel et al., 1989; Osborne and Norman, 1990; Osborne et al., 1991). The ease with which amalgam is manipulated has no equal. Placement of amalgam takes only 20-50% of the time it takes to restore a tooth with other materials. For the amalgam, this cost in placement time and the cost to purchase the material are considerably less. The one factor that amalgam does not have in its favor is esthetics. The other-restorative materials, frankly, look better.

Full textAbstract:
Dental casts are invaluable research tools. There are a variety of molding compounds available, all having temperature, humidity, and timing guidelines to ensure a precise replica of dentition. However, not all field research conditions allow for adherence to environmental guidelines requiring longer wait times prior to pouring epoxy for casting. This study, tests a common molding compound in extreme environments and over varying time intervals, testing the integrity of the dental molds in producing precise replicas of original teeth. 580 molds were created under three varying environments: room temperature, hot/humid, and cold/dry. Molds were removed from these environments in two-week intervals over twelve weeks. The resulting casts were measured to determine timing limitations for producing accurate dental casts under varying environments. Molds stored at room temperature retained their shape and size for the complete twelve weeks. Molds kept in a hot and humid environment, however, only maintained their shape and size up to four weeks, whereas molds in a cold and dry environment showed significant changes by the end of the second week. These findings provide additional tools for researchers working in a variety of field conditions allowing casts to be taken of specimens that cannot be transported off site.

Background: Metal frame denture design is common used for partially dentate patient, one of the problem was a metal appearance from wrought wire or a metal casting clasp as retainer, which is not really aesthetic. Telescopic overdenture with its double crown will be the best solution for those cases. Purpose: The purpose of this case report was to reported telescopic overdenture design and fabrication where the aesthetic was the main consideration. Case: Sixty years old female patient, a businesswoman, came to Dental Hospital of Universitas Airlangga, complained about her upper partially dentate and 6 years lower fixed partial denture, which is not comfortable to wear and her upper anterior teeth doesn’t look quite good. She wanted to make crowns and removable denture. Case management: After the diagnosis were made, the pretreatment plan were remove crown for the upper jaw, remove the bridges on lower jaw, and transitional dentures were made to maintain the VDO. The crowns and veneer were fabricated and inserted while the inner copings were tried up on prepared teeth. After the the dentures were produced, the inner copings were luted to the abutment teeth, and then the dentures were inserted using FGP (Friction GriP) cement for the friction effect. Discussion: Telescopic overdenture is consists of a double crown system known as “the telescopic”, the procedure involves fitting the remaining natural teeth with inner metal crowns, followed by outer crowns as part of an over denture that can be removed by the patient. Conclusion: This technique ensures that telescopic overdentures give natural aesthetic result.

Background/Aim: Dental impressions present a negative imprint of intraoral tissues of a patient which is, by pouring in gypsum, transferred extraorally on the working cast. Casting an accurate and precise working cast presents the first and very important step, since each of the following stages contributes to the overall error of the production process, which can lead to inadequately fitting dental restorations. The aim of this study was to promote and test a new model and technique for in vitro evaluation of the dental impression accuracy, as well as to asses the dimensional stability of impression material depending on the material bulk, and its effect on the accuracy of working casts. Methods. Impressions were made by the monophasic technique using the experimental master model. Custom trays with spacing of 1, 2 and 3 mm were constructed by rapid prototyping. The overall of 10 impressions were made with each custom tray. Working casts were made with gypsum type IV. Measurement of working casts was done 24 h later using a co-ordinate measuring machine. Results. The obtained results show that the working casts of all the three custom trays were in most cases significantly different in the transversal and sagittal planes in relation to the master model. The height of abutments was mainly unaffected. The degree of convergence showed certain significance in all the three custom trays, most pronounced in the tray with 3 mm spacing. Conclusion. The impression material bulk of 1?3 mm could provide accurate working casts when using the monophasic impression technique. The increase of the distance between abutment teeth influences the accuracy of working casts depending on the material bulk.

Full textAbstract:
Traditionally oral appliances i.e. removable orthodontic appliances, bite splints and snoring / sleep apnea appliances are made with alginate impressions and wax registrations. Our aim was to describe the process of manufacturing customized oral appliances with a new technique i.e. rapid tooling method. The appliance should ideally be custom made to match the teeth. An orthodontic patient, scheduled for conventional orthodontic treatment, served as a study subject. After a precise clinical and radiographic examination, the approach was to digitize the patient’s dental arches and then to correct them virtually by computer. Additive manufacturing was then used to fabricate a mould for a soft customized appliance. The mould was manufactured using stereolithography from Somos ProtoGen O-XT 18420 material. Casting material for the mould to obtain the final appliance was silicone. As a result we managed to create a customized soft orthodontic appliance. Also, the accuracy of the method was found to be adequate. Two versions of the described device were manufactured: one with small and one with moderate orthodontic force. The study person also gave information on the subjective patient adaptation aspects of the oral appliance.

Introduction: Tooth crowding can cause complaints if not treated early — this condition resulting in aesthetic disorders, and also masticatory and speech function disruption. The study was aimed to determine the predisposing factors of tooth crowding in the mixed dentition period by the tooth size and dental arch width. Methods: Research type was random cross-sectional. The sample was as much as 29 children with mandibular casting; then the mandibular model cast of these 6 – 9-years old children were divided into two groups according to the crowding condition in the mandibular anterior region, and the measurement was performed afterwards. Space available category was (A/A1), mesiodistal width of mandibular incisor (B/B1), total arch length (C/C1), intercanine width (D/D1), first primary intermolar width (E/E1), second primary intermolar width (F/F1), first permanent intermolar width (G/G1), interalveolar width (H/H1). Result: The results of the t-test showed significant differences (p < 0.05) in the available space for 4 incisors, where the space was larger in the non-crowded group with a difference of 2.22 mm and the mesiodistal sizes of these 4 incisors was larger in the crowded teeth group, with the difference of 1.8 mm. The results of the Pearson correlation coefficient showed a positive relationship to several measurements, namely D to C1, E to D1 and H to B1, C1, D1, F1 and G1, with the t-value > 3 and the r-value was closer to 1, which showed a correlation with strong closeness degree (r > 0.61). Conclusion: Predisposing factors of tooth crowding in the mixed dentition period were the first intercanine width (D), first primary intermolar width (E), and alveolar arch width (H).Keywords: Tooth crowding, arch dimension, mixed dentition period.

Abstract Aim: The aim of this study was to evaluate and compare the tensile bond strength of nickel-chromium alloy to dental enamel by using four different resin cements. Materials and Methods: 40 extracted central incisor teeth embedded in acrylic blocks were flattened not to expose dentin. Wax rectangular blocks of 5 mm length, 5 mm width and 1 mm height with a loop were invested and casted using Nickel-Chromium alloy by conventional induction casting method and sandblasted. Then casted rectangular blocks and 40 tooth embedded acrylic samples were divided into four groups (10 each) and cemented to tooth enamel following manufacturer's instructions as; GroupAcemented using RelyX U200, Group B cemented using Smartcem 2, Group C cemented using Multilink Speed and Group D cemented using Multilink N and then stored in artificial saliva for 24 hours. The direct pull tensile test was carried out on Universal Testing Machine at cross head speed of 0.5mm/min. Results: One way ANOVA showed a highly statistically significant (p<.01) difference between all the four resin cements. Post Hoc Tests- Multiple comparisons showed highly statistically significant (p< 0.01) difference between RelyX U200: Multilink N, Smartcem 2: Multilink Speed, Smartcem 2: Multilink N, Multilink Speed: Multilink N. Difference between RelyX U200 : Smartcem 2 and RelyX U200 : Multilink Speed was statistically significant(p< 0.05). Conclusion: Self etch resin cement (Multilink N) showed maximum mean tensile bond strength as compared to self-adhesive resin cements (Smartcem 2, RelyX U200 and Multilink Speed). Clinically the greatest advantage of self-adhesive cements is the easy and fast application technique. But this time saving technique is not as effective as self-etch resin luting agents. The presumed benefit of saving time with self-adhesive luting agents may only be realized at the expense of compromising bond strength.

Traditional methods of producing dental bars for overdentures involve tedious and time-consuming operations that demand substantial human labor and demanding skills. Though there exist several CAD/CAM systems that have been developed for various dental restorations like bridges, crowns, etc., there exists no commercial CAD/CAM system at present for design and fabrication of dental restorations for missing multiple teeth. In the research described in the present paper, CAD models of dental bars for implant-retained dental restorations were used as input for three types of fabrication processes: rapid prototyping followed by investment casting, CNC milling, and direct digital manufacturing. Details of material and process combinations and results of comparing these three types of processes, including an analysis on dimensional accuracy, are discussed.

Dentist, follow root canal therapy to treat teeth with pulpal involvement due to dental caries or as a result of trauma. In order to restore fractured and broken down teeth internal reinforcement is required in the form of a post-core restoration. The post extends into the root canal space and provides retention for the core, which subsequently helps to provide a foundation for the crown restoration. For the treatment procedure, post, core and crown are casted by an indirect procedure by taking the measurements from patient’s tooth in the form of impressions. These impressions are then converted into solid gypsum casts and then wax patterns are developed in order to facilitate casting by the lost wax technique. The final shape of the core and crown and success of the treatment entirely depends upon the skill of the dental technician and involves a number of variables in impressioning, cast poring and wax pattern fabrication. The treatment can be further simplified by making a prototype model of the post, core and the crown by taking the dimensions from the patient’s tooth. This paper presents four prototype models prepared from the solid model of the original tooth and three restored tooth.
