Background: Edentulism is an oral health problem that affects the quality of life because of the loss of equilibrium in the stomatognathic system with impaired mastication. This problem can be more deteriorating in the condition of flat ridges, which increases the stress distribution in the mucosa under masticatory load. Stress distributions that exceed the pressure-pain threshold will result in poor masticatory performance, making it critical to choose the ideal occlusal scheme for such ridge conditions. However, the measurement of stress distribution in the mucosa with various occlusal schemes is challenging for in vivo and in vitro testing because of the inability to represent the complex stomatognathic system. In silico testing using finite element analysis (FEA) can be the solution since the modeling simulation is acquired from CT-scan or digital designs and feasible experimental treatments.Objectives: This paper discusses the use of FEA in the measurement of stress distribution in the mucosa, particularly the flat ridges to different occlusal schemes in complete dentures, and its association with pain. Conclusion: The advantages of FEA in obtaining accurate modeling and testing flexibility allow the measurement of stress distribution and its association with pain on flat ridges with different occlusal schemes in complete dentures.

Background: Oral rehabilitation procedures such as crown lengthening, implants for anterior teeth, and endodontic procedures with limited tooth structure require provisional restoration for a long time. The material used in fabricating provisional fixed partial dentures is polymethyl-methacrylate (PMMA). PMMA is divided into heat cured and self-cured based on the polymerization. Heat-cured PMMA has better mechanical properties than self-cured PMMA. Despite its advantages, however, there are also some disadvantages, such as high water sorption, low color stability, and wear of use. Research on the use of eggshells as reinforcement in denture bases has been conducted. However, the use of eggshells in provisional fixed partial dentures has not been done yet. Eggshell, as an environment by-product waste material, is composed of 95% calcium carbonate (CaCO3), magnesium, potassium, and other inorganic components, can be used as alternative natural reinforced materials for PMMA provisional restoration.Objectives: To describe use of provisional restoration for a long time, PMMA as provisional restoration material, as well as the merit of eggshell as natural reinforcement material in water sorption and color stability of heat-cured PMMA provisional fixed partial dentures.Conclusion: Eggshell, which is composed of calcium carbonate, can be converted into hydroxyapatite as a reinforcement in long term provisional restoration, could improve the physical properties of heat-cured PMMA, such as water sorption and color stability.

ABSTRACTBackground: Temporary fixed partial dentures (FPD) are worn for a limited time before definitive FPD, but in some cases like crown lengthening procedures, supra structure implant, temporomandibulardisorders, and endodontic treatment, require long-term temporization. Polymethyl Methacrylate (PMMA)which is commonly used for temporary fixed dentures has weaknesses, namely porosity, low value offlexural strength and impact, low abrasion resistance, ease of fracture, shrinkage after polymerization, andleaves monomer residue, so modification is needed with the addition of reinforcing materials. Reinforcement like fiber filler is difficult to absorb resin monomers causing space between the surfaces of fiber and polymer matrix thereby reducing the mechanical strength of the resin. Eggshell is a natural source of calcium, has the potential as a biocompatible material with an economical price, and is easy toobtain as an alternative material for PMMA reinforcement. Objectives: This paper discusses the long-term use of temporary FPD, PMMA as a temporarily fixed material, and the benefit of eggshell waste to porosity and flexural strength of PMMA materials. Conclusion: The addition of eggshell to PMMA for temporary fixed restoration could decrease porosity and increase the flexural strength of PMMA material because it contains calcium carbonate so that it could be used for the manufacture of provisional fixed restoration which requires long-term useKeywords: temporary fixed denture, polymethyl methacrylate, eggshell, porosity, flexural strength

Silicone soft denture liner (SDL) is designed to absorb, reduce, and distribute pressure on denture-bearing tissues. The properties include a poor bonding strength to heat-polymerized acrylic resin base and surface roughness which promotes Candida albicans adhesion. SDL absorbs disinfectant solution during the immersion of denture in a disinfectant solution, leading to stiffness. Therefore, this study aimed to evaluate the effectiveness of oregano essential oil as an antimicrobial and the impact on the physical and mechanical properties of SDL. Antimicrobial test was conducted on 27 samples (3 groups) using disc diffusion methid and measured with a digital caliper, while surface roughness, elastic modulus, and bond strength test was performed on 20 samples (4 groups).. Surface roughness was evaluated with a profilometer. Furthermore, elastic modulus and bond strength were assessed using the universal testing machine (UTM). The results of one-way ANOVA test showed significant differences (p<0.05) in all groups of antimicrobial, surface roughness, elastic modulus, and bond strength tests showed significant differences (p<0.05). In conclusion, the addition of oregano essential oil to SDL, enhanced the antimicrobial properties, without compromising its physical and mechanical properties. Oregano extract is expected to be developed as a commercial product.

Heat cured acrylic resin is a widely known dentures base material, which is often cleaned using Cinnamomum burmannii. Therefore, this study aims to determine the effect of soaking heat cured acrylic resin dentures base on color stability. The study procedures were carried out using a laboratory experimental method with pretest and posttest control group design. The test samples comprised 24 heat cured acrylic resins divided into 6 groups, namely soaking in Cinnamomum burmannii 20%, chlorhexidine 0.2%, and distilled water for 1 and 2 years. Color stability assessement was then carried out using a colorimeter. The results showed that the average color change in the samples after soaking in Cinnamomum burmannii 20% for 1 year was 2.12 and 2.20 for 2 years. Meanwhile, the average color change after being soaked in chlorhexidine was 2.53 and 3.05 after 1 and 2 years, respectively. The results of One-way Analysis of Variance (ANOVA) showed that soaking the samples in Cinnamomum burmannii 20%, chlorhexidine 0.2%, and distilled water for 1 year and 2 years had a significant effect on color stability. The results of LSD (least significant difference) analysis after 1 year of immersion revealed a significant difference in the effects of soaking in chlorhexidine 0.2% compared to distilled water. After soaking for 2 years, a significant difference was observed in the effects of the treatment groups on color stability.

Introduction: Osteoarthritis (OA) is a disorder of the temporomandibular joint which results in permanent changes to TMJ. Scissors bite and bad habits are one of the etiological factors of OA. OA causes deviation when opening the mouth, limitations of mouth opening, and joint crepitus sounds. Use of stabilization splints (SS), physical therapy, and consumption of chondroitin sulfate-glucosamine supplements aimed at reducing joint pain, relaxing TMJ muscle, and preventing joint damage. Case report: A 22-year-old female patient came to North Sumatera of Dental Hospital with complaints stiff jaw when opening her mouth, especially in the morning. Complaints of pain occurred since skelling treatment 3 years ago. Clinical examination showed scissors bite and a habit of chewing on the right side. Palpation of the right anterior temporalis muscle revealed familiar pain and joint crepitus sound. Based on DC/TMD assessment, the patient had OA where the mouth opening is 35 mm without pain and 38 mm with pain accompanied by a left deviation of 1.5 mm. On CBCT examination there was flattening on the TMJ surface. Treatment is carried out by using SS every day and consuming chondroitin sulfate-glucosamine supplements once a day accompanied by self-therapy. Self-therapy is carried out alone by practicing opening and closing the jaw for 15 minutes every day. After 6 months is obtained without assisted mouth opening of 36 mm to 41 mm. There is no pain on palpating muscles but there is still a crepitus sound when opening and closing the mouth. Conclusion: Treatment of OA with SS, self-therapy, and consumption of Chondroitin Sulfate-Glucosamine supplements is effective in reducing TMJ joint pain and muscle stiffness through chondroitin stimulation mechanism so that prevents further degenerative processes.

ABSTRACT Background: The most common temporomandibular disorder (TMD) is characterized by disc displacement with reduction (DDWR). Despite its typical signs such as clicking, DDWR has complex symptomatic characteristics, thus; conservative treatment including occlusal splint and physical therapy are commonly performed. Physical therapy, such as acupressure using acupuncture points and massage, is an alternative to DDWR treatment. Objectives: This paper aims to explain the DDWR treatment using stabilization splints and acupressure therapy using gua sha accompanied by a massage with Kutus-Kutus oil. Case report: A 36-years-old male patient arrived at USU Dental Hospital with complaints of clicking right jaw and feeling pain in zygomatic and mandibular area. The patient has been experiencing pain under stress and during periods of high activity for the past six months. This pain is often accompanied by clenching of the jaw, particularly when the patient is worried or concentrating, and the patient tends to sleep on one side. Upon clinical examination, a sound was detected in the right temporomandibular joint (TMJ). The patient was able to open their mouth to a width of 34 mm without experiencing pain, although there was a noticeable deviation to the right. No pain was reported in the joint area during mouth opening. Radiographic examination revealed that the right and left mandibular condyles were positioned anterior to the articular tubercle. For symptomatic treatment, stabilization splints were used in conjunction with physical therapy, which included acupressure gua sha and massage with Kutus-Kutus oil. The use of a stabilization splint caused the patient to experience discomfort during clenching, which gradually led to the cessation of this detrimental habit. This intervention helped to reduce pain and eliminate the clicking sounds associated with TMJ disorder. Conclusion: the combined use of acupressure gua sha, massage with Kutus-Kutus oil, and a stabilization splint can effectively alleviate the pain and clicking symptoms in patients with TMJ disorder. Keywords: TMJ disorder, stabilization splint, acupressure, gua sha, massage

In long-span fixed partial denture restoration, especially when pier abutment is present, a non-rigid connector as a stress breaker is indicated. The Non-rigid connector is classified into a dovetail, loop connector, split pontic, cross-pin, and wing. Split pontic is an attachment placed entirely inside the pontic, particularly indicated in the tilted abutment case, to prevent the box preparation of distal pier abutment. This case report presents A pier abutment case treated with long span porcelain fused to the metal fixed movable bridge using dovetail shaped attachment, assembling the split pontic as a non-rigid connector. Split pontic acts as the stress breaker to prevent the pier abutment acts as a fulcrum. Split pontic also transfers the shear stress to the alveolar bone, minimalizes the mesiodistal torquing of the abutment teeth, and enables individual tooth movement. The advantages of this design are preparation with minimal reduction and better esthetic outcome as the porcelain build up can be done. Thus, there is no metal exposure of the restoration. Longevity and success of fixed partial denture restoration depend on the size, shape, type, and connector position. In pier abutment cases, a non-rigid connector must be considered one of the treatment choices to restore the missing teeth and preserve the abutments.KEYWORDS: pier abutment, split pontic, non-rigid connector

Disc displacement with reduction represent the early stage of disc derangement disorders. Disc derangementdisorders result from elongation of capsular and discal ligaments coupled with thinning of the articular disc.These changes commonly result from either macro or micro trauma. Mandibular repositioning splint can be usedto treat disc displacement with reduction. This clinical report aims to explain management of disc displacementwith reduction and myofacial pain with mandibular repositioning splint. 23-years-old female patient wascomplaining in mouth limited opening and pain around cheeks, ears, neck and shoulders since six months ago,especially after wake up in the morning but returned to normal a few hours later. On clinical examinations therewas a clicking sound while mouth opening and closing, also pain during palpation on facial muscles, neck andshoulders. Patient was suggested to use mandibular repositioning splint 24 hours a day for three to six months.Mandibular repositioning splint is effective if the patient uses it continuously. Functional and esthetic concernsare important if the mandibular repositioning splint is to be used during the day. The advantages of themandibular repositioning splint are least affected of speech function, more esthetic and the patient easier to movethe mandible to posterior. Mandibular repositioning splint is the best choice for disc displacement and myofascialpain treatment because it may be more acceptable from a functional and esthetic standpoint.
