Abstract

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

Backgrounds: Provisional fixed partial denture (FPD) is an important procedure in prosthetic treatment such as crown or bridge. In particular cases, like crown lengthening as preliminary treatment, implant procedure until osseointegration process, and temporomandibular disorder as an occlusal therapy, the use of provisional FPD will take 3-6 months until the insertion of definitive restoration. Therefore, materials used in making a provisional FPD should be able to preserve the prepared tooth, maintain the periodontal conditions, and have superior esthetic for a long time. Self-cure polymethyl methacrylate (PMMA) is a most commonly used material due to its biocompatibility, high wear resistance, ease of application, and superior esthetic. Nonetheless, unmodified self-curing PMMA has weaknesses due to its degradation process in the oral cavity, which affects its mechanical and physical properties. To overcome this, addition of reinforcement material, namely chitosan, in provisional FPD is necessary. Chitosan is polymer compound obtain through partial deacetylation of acetyl glucosamine through deacetylation of chitin base and modified into magnetic nanoparticles with size 100-400 nm to increase absorption power. The addition of nanotechnology to polymeric materials has shown significant appeal and improved mechanical and physical properties. Objectives: This review aims to explain the use of chitosan material in addition to self-cure PMMA provisional FPD to improve its mechanical and physical properties. Conclusion: Chitosan material can be an alternative option to improve the mechanical and physical properties of self-cure PMMA. Keywords: provisional fixed partial denture, self-cure PMMA, chitosan

Abstract

The integrity and functionality of the oral cavity may be compromised by nasomaxillary defects, such as speech, mastication, deglutition, and esthetics. Early prosthodontic rehabilitation can improve quality of life and lessen the psychological harm caused by the surgical treatment. A 70-years-old female patient was referred to the Department of Prosthodontics RSUP Dr. Sardjito Yogyakarta with chief complaints of nasal obstruction, and right-side swelling of the face. Extraoral examination revealed facial asymmetry due to swelling of the right buccal region. On intraoral examination, showing a large, firm mass extending from right palate to the midline. A multidisciplinary approach with ENT is required for the surgical treatment. A surgical obturator was made before the surgery, and immediately inserted after with TAD as a retention device. Three months later, a hollow bulb obturator and immediate lower denture was fabricated so the functional capabilities of speech, mastication, deglutition, and esthetics can be restored. Keywords: surgical obturator, maxillofacial prostheses, definitive obturator, hollow bulb

Abstract

The process of fabricating fixed dentures starts with an impression of the anatomical structure of the teeth. Currently, the use of an intraoral scanner (IOS) for digital impression has improved due to its rapid workflow. One of the advantages of IOS is the availability of the cut-out-rescan method, which involves rescanning unscanned areas (mesh holes) without the need to repeat the entire impression procedure. This method is recommended to assist in the digital workflow of fixed denture fabrication, by performing a cut-out on the prepared tooth, rescan, and merge it with the initial scan (pre-preparation scan). The accuracy of the cut-out-rescan method is measured based on trueness and precision. The aim of this literature is to describe the accuracy of the cut-out-rescan method in digital impression. Rescanning procedure influenced the accuracy of the definitive scan. The number and diameter of mesh holes influenced the scanning accuracy of IOS. The higher the number and diameter of the rescanned area, the lower the accuracy of the IOS. The narrow anatomical structure of teeth such as the anterior teeth also made the rescanning process more difficult. Nonetheless, the use of the cut-out-rescan method is quite practical and makes it easier for clinicians to perform digital workflow as there is no need to repeat impression procedure to obtain a definitive virtual cast. Clinical workflow becomes quicker by the elimination of physical casts, thus reducing clinical expenses. Keywords: IOS, workflow, cut-out-rescan, mesh holes, accuracy

Abstract

In recent years, zirconia all-ceramic restorations are widely used in crown and bridge treatment due to their superior mechanical properties and aesthetics. Zirconia is the strongest ceramic material, thus it is the treatment of choice for posterior dental restorations. One factor that affects the fracture resistance of zirconia restoration is the margin design. The shoulder and chamfer are the recommended margin design to obtain maximum fracture resistance from zirconia restoration. Shoulder is recommended because it has greater fracture resistance while chamfer is more conservative and able to withstand maximum masticatory load. However, there is still a difference of opinion regarding the fracture resistance of zirconia crown with shoulder and chamfer margin designs. This literature review aims to discuss the role of chamfer and shoulder margins design on the fracture resistance of zirconia crown. The shoulder margin design results in a wide ledge, space for adequate restoration contours and maximum aesthetics that provide resistance to occlusal forces and minimizes stress that can cause fracture. The chamfer margin design on zirconia crown has a difference in the rounded internal angle of the preparation resulting in better force distribution, better marginal fit and more resistance to fracture compared to the shoulder margin design. Chamfer margin design is more conservative and resistant to fracture due to better marginal fit which distribute stress more evenly. Keywords: zirconia, margin design, chamfer, shoulder, fracture resistance

Abstract

Lithium disilicate is a glassy ceramic material that mimics the aesthetics and strength of natural tooth structure, making it very popular in recent years. Lithium disilicate has good flexural strength, translucency, and high mechanical strength of up to 360±60 MPa which is superior to feldspathic porcelain or leucite-reinforced glass ceramic. These excellent properties make it suitable for both anterior and posterior use. Naturally, ceramic materials are inherently brittle and tend to fracture easily in repetitive function. There are several methods of fracture treatment, one of which is repair. Composite resin is frequently used for ceramic repair as a simple and fast solution. The bond strength of ceramic repairs on lithium disilicate using hydrofluoric (HF) acid is higher compared to other methods. Hydrofluoric acid that has been used as a surface treatment for lithium disilicate is 4% and 5% HF acid. This article reviews the effect of HF as a surface treatment material on bonding strength between lithium disilicate and composite resin. The application of hydrofluoric acid in ceramic surface promotes the reaction with the glass matrix that contains silica and form hexafluorosilicates. This glass matrix is selectively removed and the crystalline structure is exposed. As a result, the surface of the ceramic becomes rough and this roughly etched surface helps to provide more surface energy prior to combining with the silane solution. Silane coupling agent forms a chemical covalent bond between silica on the lithium disilicate surface and composite resin. This bond will increase the micromechanical interlock.

Abstract

Prosthetic management for edentulism could be challenging with the Inadequate interocclusal space due to enlargement of the maxillary tuberosity, causes difficulties in artificial tooth placement. Hence, reducing numbers of artificial teeth is indicated which is in line with the shortened dental arches (SDA) concept. The SDA concept could provide good occlusal and mandibular stability, comfort in mastication and appearance. An increase in strain distribution value in the anterior region of the mandible was found in the SDA due to partial changes of the occlusal load distribution pattern. Strain distribution can be analyzed using Finite Element Analysis (FEA). This literature review aims to analyse the strain distribution on SDA complete denture using finite element analysis. The SDA concept was aimed at preserving the anterior and premolar regions. Masticatory ability is correlated with the number of teeth and is impaired if there are less than 20 teeth. Based on FEA, the increase in strain distribution value in the SDA concept is due to changes in occlusal load distribution pattern, masticatory muscle activity and tissue morphology that is susceptible to stress. Nevertheless, the strain value in SDA models were of lower intensity than the yield reported to cause deterioration effects. In maxillary complete denture, the highest strain value was found at the incisal and labial frenal notches. Strain distribution on shortened dental arches using finite element analysis shows a satisfactory masticatory ability and an increase in the value of stress distribution in the anterior region of the mandible.

Abstract

Edentulism is an oral health problem that has an impact on quality of life because it causes a loss of balance in the stomatognathic system with disruption of mastication. The impaired masticatory function can be exacerbated from knife-edge conditions, thus the masticatory load received by the mucous in the form of stress distribution becomes greater. One of the efforts to reduce stress concentration is to modify the occlusion concept and anatomical shape of the artificial teeth. However, measuring the stress distribution on edentulous mucous with various occlusion schemes was difficult with in vivo and in vitro tests due to inability to represent the complex system of stomatognation. In silico test with A) can be a solution because the modeling simulation is obtained from CT-scan or digital design. This paper discusses the stress distribution analysis on knife-edge condition with various occlusion schemes using FEM. Stress distribution that exceeds the mucous pressure-pain threshold during denture function will cause poor mastication performance. This paper discusses the analysis of stress distribution under knife-edge ridge conditions with various occlusion schemes using FEM. Stress distribution that exceeds the mucous pressure-pain threshold during denture function will cause poor mastication performance. The use of Lingualized or Monoplane occlusion schemes can be a solution because they use semi-anatomical and non-anatomical artificial teeth to reduce the load passed on the cusp and also minimize resistance during lateral movement. The advantages of FEM in obtaining accurate modeling and flexibility in testing allow analyses that are difficult to perform in in vivo and in vitro, FEM measure stress distribution and its relationship with pain on knife-edge ridge base on various occlusion schemes in complete dentures.

Abstract

Overdenture is removable denture used to replace missing teeth and cover or rest on one or more remaining natural teeth in the mouth. The concept of overdenture is a positive means for delaying the process of complete edentulism and helps in reducing bone resorption. Selection of teeth to be retained by looking at periodontal tissue and history of dental caries. Tooth-supported overdenture using coping can be made with short coping, medium coping, or long coping. Metal copings can be used on teeth that have decreased alveolar bone support but are still strong, also covering dentin tubules. On this report, A 62-year-old man patient reported having the chief complaint of difficulty in chewing food and speaking due to missing teeth in the upper and lower arch. This case report describes prosthodontic rehabilitation of a mandibular partially edentulous arch with tooth-supported overdenture using metal medium copings which aim to provide sensory response with further stability and retention to the denture. The patient was satisfied with the treatment outcome. For elderly edentulous patient with few remaining teeth, a tooth-supported overdenture is one of the best and most practical, feasible, and comfortable treatment alternatives.
