Abstract

Proses menua (lansia) adalah proses alami yang disertai adanya penurunan kondisi fisik, psikologis maupun sosial yang saling berinteraksi satu sama lain. Perubahan secara biologis ini dapat mempengaruhi status gizi lansia yang berkaitan erat dengan menurunnya aktivitas biologis tubuhnya dan berpotensi menimbulkan masalah kesehatan secara umum maupun kesehatan jiwa secara khusus pada lansia. Tujuan program ini adalah untuk meningkatkan kualitas hidup lansia melalui perawatan gigi yang mengganggu seperti gigi goyang dan berlubang, serta pembuatan gigi tiruan. Program ini dilakukan dengan tiga tahap dengan masing-masing tahap dilakukan oleh pakar prostodonsia, psikologi, dan rongga mulut dengan prosedur sesuai bidangnya. Hasil dan capaian yang diperoleh pada program ini terpenuhi sesuai dengan permasalahan yang terdapat pada masing-masing bidang. Kesimpulannya, penyuluhan yang dilakukan memberikan pengaruh positif untuk pengetahuan tentang akibat dan perawatan kehilangan gigi, serta motivasi untuk memakai gigi tiruan menjadi ada.

Abstract

Loss of eye have physiologic and social impact on patients, especially in pediatric patients. To overcome this problem ocular prosthesis can be made similar with the color, shape, size and movement of the patient’s eye, so the ocular prosthesis can look like natural eye. The various methods, techniques and concepts documented in this case re-port with modifications to the physiologic impression and making of iris buttons aim to get the better movement of the prosthesis and 3D profile of the iris. A 6-years-old female patient came to the USU Dental Hospital to fabricate a new eye prosthesis. The patient had a medical history of retinoblastoma at the age of 2 years and had enucleation surgery. The eye is rehabilitated with fabrication of a custom ocular prosthesis with modifications on physiologic im-pression and iris button making. Modifications to physiologic impression and modifications to the fabrication of iris buttons will provide movement, shape and 3D effects of iris that are better than stock eye prosthesis. It is concluded that custom ocular prosthesis with modification on physiologic impression provide a better and more natural move-ment. While modification on making iris button using customized iris button cuvette will facilitate the process of ma-king iris button.

Abstract

Loss of eye does not only affect facial esthetics but also psychological health of the patient and leads to social disa-bility. A custom-made ocular prosthesis is a good alternative to promote physical, psychological and esthetically plea-sing appearance that can improve social acceptance of the patient. A 5-years-old female patient and 18-years old male patient were reported to Dental Hospital USU with the chief complaint of loss of an eye, making them often in-sulted by schoolmates, while the male patient lost confidence on socializing around. In these cases, ocular prosthe-ses with modification of custom tray was made by using a putty index obtained from wax pattern to produce a better fitting ocular prosthesis so it expected to be retentive as to produce comfort and increase patient confidence. Con-tact between ocular prosthesis and tissue bed is necessary to evenly distribute the pressure obtained with proper im-pression technique. This technique ensures a good fit of the custom tray thereby produce accurate adaptation to the tissue surface can increase the movement of the prosthesis and provide a good natural esthetic outcome. Post evi-sceration patients need psychological support to restore confidence and self-esteem in today's cosmetics challenging world. For these cases, patients’ self-confidence was restored and socializing as before without any embarrassment.

Abstract

All-ceramic restorations have been widely used in prosthodontics as metal-free restoration because of their esthetics, biocompatibility, and inert properties. However, fracture remains a complication for all-ceramic restorations. All-ce-ramic posterior restorations encounter significant fracture after 5 years of usage than anterior region. Stress distri-tribution in all-ceramic restorations during mastication is higher on cervical margin than other surfaces according to finite element analysis. Shoulder and chamfer finish line are recommended designs for maximum fracture resist-ance of restoration and had influence in stress distribution. Mechanical properties of restoration material such as flex-ural strength, modulus of elasticity (ME), and fracture resistance are important factors that must be considered for its durability. Increasing ME of restoration material will increase strength of fracture. Zirconia usually used because of its superior fracture resistance among other ceramic material (ME±205 GPa). Shoulder is recommended in zir-conia because of greater fracture resistance but other literature suggests chamfer. Lithium disilicate has an improved physical properties and translucency ceramic restoration and is recommended as an alternative treatment (ME±96 GPa). In lithium disilicate, shoulder and chamfer have almost equal fracture resistance. PEEK is a thermoplastic semi-crystalline material with ME near human cortical bone (±3.6 GPa) with shock absorption properties. This litera-ture review role of all-ceramic restoration finish lines design on stress distribution. Shoulder and chamfer still the main choice in FPD but which design is most appropriate still undecided.

Abstract

Desinfeksi gigi tiruan yang teratur biasanya dapat mencegah pertumbuhan mikroorganisme yang tidak diinginkan ini dan masalah klinis yang terkait, seperti denture stomatitis. Metode desinfeksi untuk gigi tiruan termasuk metode mekanis, kimia dan kombinasi. Metode desinfeksi kimia terbukti lebih baik bagi pemakai gigi tiruan. Klorheksidin 0,2% adalah desinfektan kimia yang sering digunakan untuk gigi tiruan karena bersifat bakterisida dan fungisida. Salah satu bahan alternatif yang memiliki sifat biokompatibilitas dan bersifat bakterisida dan fungisida adalah minyak jarak. Kekuatan transversal dianggap sebagai sifat mekanis yang sangat dipertimbangkan untuk semua bahan kedokteran gigi karena kekuatan transversal menunjukkan kekuatan atau ketahanan bahan tersebut. Tujuan penelitian ini adalah untuk mengetahui nilai dan pengaruh desinfeksi gigi tiruan resin akrilik polimerisasi panas dengan klorheksidin dan minyak jarak (Ricinus Communis oil) terhadap kekuatan transversal. Rancangan penelitian ini adalah eksperimental laboratoris. Sampel pada penelitian ini menggunakan resin akrilik polimerisasi panas dengan ukuran 64×10×3,3 mm untuk perhitungan kekuatan transversal dengan jumlah seluruh sampel 30 sampel. Sampel didesinfeksi dengan khlorheksidin dan minyak jarak dengan simulasi 3, 4, dan 5 tahun. Hasil penelitian ini menunjukkan bahwa tidak ada pengaruh desinfeksi gigi tiruan resin akrilik polimerisasi panas dengan klorheksidin 0,2% dan minyak jarak terhadap kekuatan transversal. Disimpulkan bahwa tidak ada pengaruh desinfeksi dalam minyak jarak 10% dan klorheksidin 0,2% selama 3, 4 dan 5 tahun terhadap kekuatan transversal.

Abstract

Background : Porcelain fused to metal (PFM) restoration is one of the most common restorations for fixed dentures because of its high strength, durability, biocompatibility, and satisfactory esthetics. The brittle nature of ceramic makes it easily fractured. Porcelain fracture is the second largest failure after caries. Repairing porcelain directly using composite resin becomes an option because it is cost-effective and easy to apply. The repair process requires chemical and mechanical bonding to create a strong resin bond. Hydrofluoric acid (HF) can be used as a surface treatment material to achieve good bonding. Concentration and etching time affect the bond strength. However, HF becomes harmful when in contact with soft tissues. Strict protocols in its application are observed and prolonged use in the mouth is avoided. Objective: To describe the effect of HF as a surface treatment material on bonding strength between porcelain and composite resin. Knowing the HF bonding strength changes to time and concentration as a surface treatment material for direct repair. Conclusion : Minimizing the contact of HF on soft tissues, applying HF in the mouth for a short time without reducing its function to achieve good bonding strength. Keywords : porcelain fused to metal, surface treatment, hydrofluoric acid
