Abstract

Since the outbreak of Covid-19, with every mutation, it has posed various challenges to human life and in health sciences. Patients on corticosteroids or with comorbidities like diabetes mellitus are at increased risk of post Covid-19 infections like mucormycosis. Mucormycosis is a rare opportunistic infection, often associated with immunocom-promised states. Fungal invasion of the hard palate, paranasal sinuses, orbits and brain is the commonest form of rhinocerebral mucormycosis. Among the medical professionals involved in managing patients with mucormycosis, maxillofacial prosthodontists are responsible for prosthetic treatment of lost oral and maxillofacial structures, help-ing patients to socialize and have an acceptable quality of life after surgical treatment. This literature review is aimed to describe maxillofacial prosthodontist challenge in rehabilitation of mucormycosis post Covid-19 infection. It is concluded that prosthodontist face many challenges in mucormycosis rehabilitation. Prosthodontist should be ca-pable to early detection and diagnosis, carefull in planning and designing the prosthesis, wise in using of softliner material, and should always maintain long-term follow-up if any sign of lesion recurrence.

Abstract

Edentulous induces the function of the stomatognathic system particularly masticatory performance. The conse-quence that occurs in complete edentulous is the resorption of residual ridge and can alter the morphology of al-veolar bone gradually from well-rounded to knife-edge ridge form. Excessive occlusal load absorbed by the knife-edge alveolar ridge when the denture is exposed to masticatory loads enhances ridge resorption and more complex treatments are needed in manufacturing complete dentures (CD). Soft denture liners (SDL) overcome CD problems with knife-edge ridges by utilizing the cushioning effect by distributing the load evenly to the alveolar ridge. The most popular method used today to evaluate the stress distribution at the alveolar ridge is finite element analysis (FEA) because it presents information in both qualitative and quantitative forms. This study is aimed to evaluate the differ-ences in stress distribution received by knife-edge ridges in CD with SDL. Denture base applied with acrylic soft den-ture liner (ASDL) and silicone soft denture liner (SSDL). It is concluded that ASDL provides a better stress distribution than SSDL because of its viscoelasticity, while SSDL is superior in terms of durability.

Abstract

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.

Abstract

ABSTRACTBackground: In teeth with short clinical crowns that will be used as a support for metal porcelain fixed dentures, the problem that often occurs is that the dentures easily fall off after being installed. Surface treatment is one of the efforts to increase retention. Advances in laser technology provide advantages in increasing microstructural and wear resistance on the metal surface of the crown that will be used as abutment teeth.Objectives: In addressing the retention problem of short clinical crowns, modification of tooth preparation, casting, and proper cementation procedures need to be considered. Improving the mechanical properties by surface treatment of the dental crown to be cemented by modifying the strength and focus of the laser diameter can play a role in surface roughness and shear bond strength.Conclusion: The use of lasers to increase microstructural and wear resistance in teeth with short clinical crowns can minimize the failure of making metal porcelain fixed dentures. Keywords: fixed denture, short clinical crown, surface roughness, shear bond strength, laser

Abstract

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

Abstract

Background: Heat-cured acrylic resin is a commonly used material for removable denture bases but has a low mechanical strength. Heat-cured acrylic resin used as a denture base must be kept clean by immersing the denture in a cleaning agent. Denture cleaning materials on the market generally come from chemicals. Immersion of heat-cured acrylic resin as denture base in chitosan solution can inhibit the growth of Candida albicans better than oxygenizing denture cleaning solution. Biologically, chitosan is safe because it has biocompatible and biodegradable properties. Objectives: To determine the effect of immersion of heat-cured acrylic resin in chitosan solution on hardness, transverse strength, and modulus of elasticity. Materials and method: 25 acrylic resin plates measuring 65 x 10 x 2.5 mm divided into five groups. Each group was immersed in a solution of 1%, 2%, 3% chitosan, distilled water, and 1% ascorbic acid, then tested for transverse strength using the Universal Testing Machine. The values ​​of transverse strength and modulus of elasticity were calculated using the formula. Hardness test pre and post-test used 15 acrylic resin plates measuring 12mm x 12mm x 3mm were divided into five groups with each group immersed in 1%, 2%, 3% chitosan solution, distilled water, and 1% ascorbic acid. Results: Statistical analysis used one-way ANOVA for each test. The only significant difference was the modulus of elasticity between the immersion groups. The value of transverse strength, modulus of elasticity, and hardness was higher in the group with a 3% chitosan solution, with no difference statistically in transverse strength and hardness between groups. Conclusion: there was a significant difference in the effect of elastic modulus from the immersion of heat-cured acrylic resin in solution distilled water and 1% ascorbic acid as a control and 1%, 2%, and 3% chitosan solutions with ascorbic acid as a solvent

Abstract

Heat polymerized acrylic resin is the most frequently used type of acrylic resin because it has several advantages. Heat polymerized acrylic resin dentures must be disinfected to maintain cleanliness and prevent diseases caused by wearing unclean dentures.. The chemical method is a good and easiest method to do by immersing the dentures in a disinfecting solution. The immersion will clean the surface of the denture and reach the undercut area of the denture. Chlorhexidine and castor oil are ingredients that have substances that can clean dentures, but the content in these materials has an influence on the properties of dentures, one of which is mechanical properties. This study aimed to know the effect of disinfection of chlorhexidine and castor oil based on time of use on the impact strength of heat polymerized acrylic resin denture bases with simulations of 3, 4, and 5 years. The sample was tested using a Charpy Impact Tester to determine the impact strength value. This study showed that there was an effect of castor oil on the impact strength of heat polymerized acrylic resin, but the change still above the minimum value, so this can be suggested as a disinfection material.

Abstract

Hemimaxillectomy will create oro-nasal communication which can affect the function of swallowing, masticatory, speech, aesthetic and psychological. This case report describes a method of prosthodontic management of maxillary defects using an obturator prosthesis with a hollow bulb. A 15-year-old male patient was diagnosed with central giant cell granuloma, therefore hemimaxillectomy was performed by ENT doctors at RSUP Dr. Sardjito. He has a surgical obturator that was inserted by a prosthodontist immediately after the surgery. Three weeks after surgery, soft tissues were ready to be made an interim obturator. Seven months later, he came to RSGM Prof. Soedomo with a complaint the old obturator is difficult to adapt. Intraoral examination revealed a large palate defect in the right palate durum segment (Aramany's class II type maxillary defect) and half of the right maxilla is missing. A definitive obturator using metal combination acrylic with a hollow bulb was made to cover the maxillofacial defect and replaced missing teeth. That prosthesis can cover the defects of the maxilla so the patient can speak well, and the function of masticating and swallowing can be restored. Keywords: surgical obturator, definitive obturator, hollow bulb
