Scientific Achievements

Purpose: The purpose of this paper is to analyse attempts at improving the bond between acrylic artificial teeth and the denture base plate - considered in the context of single incisors in framework denture. Design/methodology/approach: It is a review article focusing on the analysis of state of the art in the field of the bond between the polymerised acrylic (teeth) and the polymerising acrylic resin during the production of denture (denture plate). Previous works regard the issue of individual incisor teeth (both upper and lower) breaking off from the metal partial denture. Findings: The bond between artificial acrylic teeth and the acrylic denture plate of the prosthesis was discussed. Ways of improving this bond were also presented. Although researchers and companies offer many methods for improving this bond, none of them refer directly to the issue discussed in this article. In conclusion- the hitherto scientific achievements work well in the case of acrylic prostheses without a metal frame, which constitutes an obstacle for achieving the effect required. In this work, it is suggested that further research would not only develop and provide more detail on the issue of the bond between artificial teeth and the denture plate, but also solve the problem appearing in cases of metal partial denture. Originality/value: This article shows a significant problem that hasn’t been discussed in detail in the past.

Introduction. Complete denture reinforced with metal bases is fabricated in cases of fracture risk as well as in selected patients with neuromuscular disorders. The aim of this report was to present different designs of metal framework for complete denture and their advantages in the treatment of edentulous patients. Material and Methods. The study included 116 edentulous patients who received complete dentures. The respondents were divided into two groups according to the type of denture used. Thirty one patients were rehabilitated with complete dentures reinforced with metal base, whereas 85 patients received conventional complete acrylic dentures. Metal bases were fabricated using Co-Cr-Mo alloy. Two designs different in regards to the vibrating line were fabricated: metal frame extended to the vibrating line and acrylic resin extended to the vibrating line. After investing and casting, metal bases were electropolished. Subsequent processes of arranging artificial teeth, waxing, flasking and finishing completed the fabrication process of dentures. Results. Denture base fractures were prevented in majority of patients. The design of upper denture where metal frame was extended to the vibrating line and metal base with elongation over the convex edentulous ridge in lower jaw were the most favored and successful in prosthetic rehabilitation of experimental group of edentulous patients. There was no need for rebasing of complete dentures reinforced with metal base. Conclusion. Complete denture reinforced with metal base presents a favorable design for rehabilitation of edentulous patients with well pronounced edentulous ridges and low tendency to resorption.

Metal framework denture is needed in patient with tooth loss accompanied by the presence of periodontal disease inthe remaining tooth is needed. This denture primarily maintains the existing teeth post periodontal treatment. Theuse of metal framework in this case can help to prevent tooth movement and maintain tooth position afterperiodontal treatment. Therefore, the success of the treatment can be achieved because the metal characteristic ismore rigid when compared to other dental materials. This paper discusses the use of frame denture in patient afterperiodontal treatment on the remaining teeth in lower arch. It can be concluded that removable denture with metalframe combined with splint must be done on mobile teeth, to decrease mobile teeth and to preventincreasing of periodontal tissue damage after periodontal treatment.

Introduction: The denture base is the part of the removable denture that is supported by good adaptation to the underlying oral tissue. Most of the denture bases are made of acrylic or polymethyl methacrylate resin, better known as PMMA. However, the acrylic resin also has disadvantages such as easily broken and absorbs liquids both water and chemicals. The chemical absorption like alcohol, ethanol, and some drinks that contain acidic materials will chemically be induced with acrylic resin and settle in the pores of the acrylic resin. The chemical damage or defect creates roughness on the surface of the acrylic resin which can cause cracking or crazing and a decrease in surface strength and hardness. Materials and Methods: The method used in this research was a laboratory experimental design with a post-test-only control group using 12 samples consisting of 2 different types of samples by measuring the surface roughness of the acrylic resin after immersing the sample with a predetermined time. Results and Discussions: One-way ANOVA test results showed a significant difference in surface roughness after the samples immersion with a value of p = 0.006 (p <0.05). Conclusions: Based on this research, can be concluded that there is an increase in the surface roughness of the heated polymerized acrylic resin for 3 hours and 4 hours of immersion. The longer the heated polymerized acrylic resin is soaked in arak hence the level of surface roughness increases.

Edentulism has been a severe public health problem in industrialized countries due to aging and poor oral care. Design and fabrication of the complete dentures are mainly using conventional methods involving an enormous series of clinical and laboratory procedures. Edentulous patients have to make several visits to the clinic for the traditional fabrication of denture. Now the unceasing developments occur over several years. Present-day technological innovations allow the use of various systems with computer‑aided design/computer‑aided manufacture (CAD/CAM) technology to produce complete dentures has seen exponential growth. There are different manufacturing techniques of CAD-CAM complete denture like AvaDent, Wieland digital denture, Baltic denture, DENTC system. CAD-CAM technology requires only two appointments for the patient to get their complete removable denture. A reduction in clinical chair time also shortens the cost of care. The improved fit of the denture was because of fewer processing errors. It simplifies the re-manufacturing of lost/broken prostheses due to the digital storage of denture data. The pre-polymerized acrylic resin used by manufacturers for the fabrication of a denture base delivers excellent fit and strength when compared to conventionally processed bases. It doesnt show any polymerization shrinkage as there is a less residual monomer. Hence, it reduces the potential infections as fewer candida albicans attach to the denture bases. The motive of this article is to highlights the benefits of CAD-CAM technology over conventional denture fabrication.

Acrylic resin is the most commonly used denture base material. However, it has a shortage of being easily broken. One way to resolve this problem is by adding polyethylene (PE) or glass fibers. The purpose of this research is to compare the transversal strength of PE and glass fibers from denture plate acrylic resin repair material. The experiment involved 32 plates of heat cure acrylic with the dimensions of 65 mm x 10 mm x 2.5 mm. The speciments were prepared to create a 3 mm gap and 45° bevel. Subjects were divided into 2 groups, each group containing 16 plates. Group I was reinforced with PE fiber and Group II was reinforced with glass fiber. All plates were soaked in distillation water for one day at 37 °C. Plates were tested for transverse strength with universal testing machine and all data were analyzed with independent t-tes at 95% confidence level. Macro photo analysis was used to observed the bond failure on fiber and resin. The mean of transverse strength (MPa) denture plate acrylic resin repair material reinforced with PE fiber was (67.38 ± 4.31) MPa, while glass fiber was (93.61 ± 6.14) MPa. Independent t-tes showed that type of fiber had a significant effect (p<0.05). Thus, it is possible to conclude that addition of glass fibers in denture plate acrylic resin repair material increased the transverse strength and made it stronger than those added with PE fibers.

Objective. To evaluate the shear bond strength between different artificial teeth and denture base polymerized by two polymerization methods submitted to thermocycling. Materials and Methods. Two acrylic resins were selected according to the polymerization method (water-bath and microwave), and four different artificial teeth (Biotone, Dentsply; Trilux, Vipi Dent; Premium 8, Heraeus Kulzer; Soluut PX, Yamahachi) were also tested. The polymerization of the acrylic resin was performed by using conventional cycle (8 h at 74°C) in water-bath and using two cycles (20 min at 270 W + 5 min at 360 W) by the microwave method. The shear bond strength was evaluated after 24 h of water storage at 37°C (immediately) and after the thermocycling test (5,000 cycles, 5–55°C). The shear bond strength (n=10) was performed using a universal testing machine (Instron 4411) at a crosshead speed of 1.0 mm/min. Modes of failures were classified as cohesive and adhesive. The data (MPa) were statistically analyzed by three-way ANOVA, and the mean values were compared by the Tukey test (α = 0.05). Results. In general, the polymerization by microwave showed the highest shear bond strength values, and Trilux artificial teeth had the lowest bond strength values (p<0.05). Thermocycling did not affect the shear bond strength (p<0.05). There was a predominance of cohesive failures for all groups. Conclusions. The chemical composition of the artificial teeth affects the bond strength, and the microwave method is preferable to perform the acrylic resin polymerization.

The Aesthetic

In making removable denture, some aspects must be considered: retention, stabilization, support, comfort, andaesthetic. Retention plays an important role in the success of a removable denture. Retention can be obtained from theundercut area, or friction of the denture’s components to the abutment or abutment. Clasp as a retainer, both of metalcasting and wire have been frequently used in the removable partial denture. The clasp has some shortcomings in itsusing, namely color of the metal can sometimes interfere with the aesthetic of the wearer and cannot be placed on teeththat have experienced extensive caries. Telescopic crown as retainer has several advantages, which can be used oncrown of abutment that has experienced extensive caries or tooth that will be an abutment but have endodontic-treated.On telescopic crowns, retention is obtained from the friction between the primary crowns against secondary crown thatserves as a retainer. This case report describes two cases of a removable denture with a metal framework using atelescopic crown on one tooth that serves as a retainer in the case of one-side free-end edentulous.
