Abstract

Cases of cleft lip and palate (CLP) in infants were many in Medan and surrounding areas.There were about 150 cases of infants with CLP in a year handled by Mitra Sejati Medan Hospital andGrandmed HospitalLubuk Pakan,butthetreatmentgiven was only surgical treatment,while the follow-up care,which isthefabricationofartificialpa-late or feeding plate before or after surgery,cannot be facilitated.Until now CLP further treatment cannot be done becausetheparentsdonotknowthetreatmentand most of them came from groups with low socio-economic level andthefabricationof feedingplaterequiredhigh costs.To overcome this problem,we held communityserviceby fabricating feeding plates as feeding aids for babies with CLP.The method used to achieve this goalofserviceis collectingdatafrompatientswithCLPinthetwohospitals,generalexaminationbypediatrician,makingtheimpression of the oral cavity to create the working cast,making outline design,doing thewaxpatternandfeeding plate fabrica-tioninthe laboratory using hard and soft acrylic materials combination.The insertion of feedingplatesisperformed at the hospital and evaluated whether the baby can drink milk normally using a bottle. Body weight changes are evaluated every month until the baby is declared ready for surgery.

Abstract

Temporomandibular disorder (TMD) is the common term used to describe a range of disorder affecting the temporomandibular joint (TMJ). Facial pain is a common symptom that patients present to their dentist, and TMDs represent a significant proportion of the non-dental causes of this pain. These disorders can have a profound effect on a patient’s quality of life. The management goals for the prosthodontist are patient comfortable, occlusal stability and the complex restoration of the teeth.

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

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

Digital impression of partial edentulous in removable partial denture requires special attention, based on Kennedy's classification, amount of tooth loss and position will affect the accuracy of digital impression. Factors affecting accuracy of intra oral scanner are handling and learning, powdering, lighting, scanning distance, and scanning strategy. The scanning strategy is a certain movement when scanning to improve the accuracy of the virtual model. The accuracy of the scanning strategy in digital impression can be assessed based on trueness and precision. This literature review aims to explain the various scanning strategies on partial edentulous on digital impression accuracy. Most IOS manufacturers recommend specific scanning strategies. In removable partial dentures, it was found that modified scanning strategies were more accurate than the manufacturer's recommended scanning strategies in some clinical situations. For cases in Kennedy Class IV and Class III maxillae the scanning strategy from occlusal to palatal and then to buccal proved to be more accurate. In Kennedy's Class I maxilla, the T-R (Teeth-Ridge) strategy was more accurate than the M (Manufactured) and R-T (Ridge-Teeth) strategies with reduced seesaw effect and high stabilization of the partial removable denture framework. This requires special strategies that depend on the IOS system. The scanning strategy affects the accuracy of digital impression, where the manufacturer's recommended scanning strategy is not necessarily better than the modified scanning strategy. In addition, the location and case of tooth loss also affect the scanning strategy. Key word: strategy scanning, digital impression, trueness, precision, intra oral scanner
