Background: The masticatory system as a biologic system is subjected to harmful influences of varying severity. Almost half of routine patients requesting prosthodontic treatment indicated at least one sign or symptom of temporomandibular disorders. Analysis of the masticatory system often neglected by dentist. Untreated temporomandibular disorders may significantly implicated in the perpetuation of the disorder and may interfere with routine prosthodontic clinical procedures. It would be resulted unsuccessful long term goal of prosthodontic rehabilitation because of the uncompleted diagnoses and treatment plan. Purpose: The purpose of this case report was to give the information of the importance of masticatory functional analysis in the diagnostic finding for treatment planning in the prosthodontic rehabilitation. Case: A 45 year - old male patient, partial dentate with reduced chewing efficiency, mild pain in right preauricular region in function, left click in opening mouth, severe attrition on all anterior lower teeth with vertical dimension of occlusion decreased due to loss of posterior support. He wanted to make a new denture. Case management: Record and analyze of active and passive mandibular movement, opening pathway, muscle and temporomandibular joints palpation, load testing, and vertical dimension of occlusion with manual functional analysis (MFA), occlusal condition and radiographic examination. Treatment plan was formulated into 3 phases: stabilization of the masticatory system, definitive treatment and periodical control. The result of this treatment excellent for 1 year evaluation after permanent cementation. Conclusion: Masticatory functional analysis is very important and must be done in the diagnosis finding for treatment planning in every case of prosthodontic rehabilitation.Latar belakang: Sistem pengunyahan sebagai sistem biologis sewaktu-waktu dapat terjadi gangguan dengan berbagai derajat keparahan. Hampir setengah dari jumlah pasien yang memerlukan perawatan prostodontik minimal menunjukkan satu tanda atau keluhan dari gangguan temporomandibular. Analisis fungsional sistem pengunyahan masih sering dilupakan oleh dokter gigi. Gangguan temporomandibular yang tidak dirawat akan terus ada dan mungkin dapat mengganggu prosedur klinis perawatan prostodonsia. Hal tersebut akan menyebabkan keberhasilan klinis jangka panjang perawatan prostodonsia tidak dapat tercapai karena diagnosis dan rencana perawatan yang kurang lengkap. Tujuan: Tujuan dari laporan kasus ini adalah untuk memberikan informasi tentang pentingnya analisis fungsional sistem pengunyahan untuk menegakkan diagnosis dan rencana perawatan pada perawatan prostodonsia. Kasus: Pasien laki-laki usia 45 tahun, bergigi sebagian merasa sulit untuk mengunyah makanan, nyeri ringan di daerah depan telinga kanan saat fungsi, keletuk sendi kiri saat membuka mulut, atrisi pada seluruh gigi depan rahang bawah disertai penurunan dimensi vertikal oklusi akibat kehilangan dukungan gigi belakang. Dia ingin membuat gigi tiruan yang baru. Tatalaksana kasus: Mencatat dan menganalisis pergerakan aktif dan pasif rahang bawah, arah pergerakan rahang bawah saat membuka mulut, palpasi otot-otot pengunyahan dan sendi temporomandibula, uji beban, dimensi vertikal oklusi dengan metode analisis fungsional secara manual, keadaan oklusal dan radiologis. Rencana perawatan dibagi menjadi 3 tahap berupa stabilisasi sistem pengunyahan, perawatan tetap dan kontrol secara periodik. Hasil perawatan menunjukkan keberhasilan klinis yang baik setelah dilakukan evaluasi selama 1 tahun setelah penyemenan tetap. Kesimpulan: Analisis fungsional sistem pengunyahan sangat penting dan harus dilakukan untuk menegakkan diagnosis dan rencana perawatan pada setiap perawatan prostodonsia.

Titanium - ceramic restoration: How to improve the binding between titanium and ceramic Harry Laksono
Dental Journal (Majalah Kedokteran Gigi) Vol. 44 No. 1 (2011): March 2011

Background: Titanium alloys has been used as an alternative to nickel-chromium alloys for metal-ceramic restorations because of its good biocompatibility and mechanical properties. This indicated that it was possible to design coping according to standards established for metal-ceramics. However, titanium is chemically reacting strongly with gaseous elements which causes problems when ceramics are fused to titanium. Purpose: To provide information about improving the bonding between titanium and ceramic. Review: Titanium has two crystal modifications, the close-packed hexagonal (α) structure, up to 880° C, and above this temperature the bodycentered cubic (β) structure. The principal problems is the extensive dissolution of oxygen resulting in thick, oxygen-rich titanium layers called α-case that harms the bonding of ceramic to titanium and the great mismatch in the coefficient of thermal expansion of conventional ultra-low fusing ceramic. Methods have been developed for fusing ceramic to titanium like processing methods, the used of ultra-low fusing titanium ceramic, bonding agent, and protocol for ceramic bonding to titanium. Conclusion: Titanium and titanium alloys, based on their physical and chemical properties suitable for titanium-ceramic restorations, but careful selection of processing methods, ceramic materials, laboratory skill and strict protocol for ceramic bonding to titanium are necessary to improve the bonding between titanium and ceramic.Latar Belakang: Logam campur titanium telah dipakai sebagai salah satu bahan alternatif untuk logam nikel-krom pada pembuatan restorasi keramik taut logam karena mempunyai biokompatibilitas dan sifat mekanik yang baik. Hal ini menunjukkan bahwa logam titanium dapat dipakai untuk pembuatan koping logam berdasarkan standar yang dipakai untuk pembuatan restorasi keramik taut logam. Meskipun, secara kimiawi logam titanium bereaksi dengan elemen-elemen gas yang menyebabkan masalah pada perlekatan keramik pada titanium. Tujuan: Memberikan informasi tentang cara meningkatkan kekuatan perlekatan antara keramik dengan titanium. Tinjauan: Titanium mempunyai 2 struktur kristal, struktur close-packed hexagonal (α) diatas 880°C dan struktur bodycentered cubic (β) dibawah 883°C. Masalah utama adalah pelepasan gas oksigen yang menghasilkan lapisan titanium kaya oksigen yang tebal disebut α-case yang menghalangi perlekatan keramik pada titanium dan koefisien ekspansi panas dari bahan ultra-low fusing ceramic yang berbeda dengan titanium. Berbagai cara telah dikembangkan untuk mendapatkan perlekatan keramik pada titanium seperti teknik pembuatan, pemakaian bahan ultra-low fusing titanium ceramic, bahan bonding dan protokol untuk perlekatan bahan keramik pada titanium. Kesimpulan: Titanium dan logam campur titanium, berdasarkan sifat-sifat mekanik dan kimiawinya dapat dipakai untuk pembuatan restorasi keramik taut logam, tetapi pemilihan teknik pembuatan, bahan keramik, ketrampilan peteknik gigi dan mengikuti protokol untuk mendapatkan perlekatan keramik pada titanium dengan benar diperlukan untuk meningkatkan kekuatan perlekatan antara keramik dan titanium.

High-strength all-ceramic systems for fixed partial dentures (FPDs) is gaining popularity as an alternative to the well established metal-ceramic FPDs. Several new framework materials and technique such as lithium disilicate, aluminum oxide and yttrium tetragonal zirconia polycrystal have been developed with improved strength, marginal discrepancy and esthetics. Since not every all-ceramic system can be used for a variety application, proper selection of the materials is an important for the success of all-ceramic FPDs. The longevity of dental restorations is an important health concern and the clinician placed great emphasis on mechanical properties to define the clinical indication of the ceramic materials because of their brittleness and low fracture toughness. The stronger and tougher framework material would improve the reliability and the longevity of dental restoration. To fabricated of an all-ceramic FPDs, material would be required with a flexural strength in excess of 300 MPa and fracture toughness 3 MPa/m½. Zirconium has a better mechanical properties than alumina and lithium disilicate glass-ceramic, result from the transformation toughening, free of glass phase and minimal flaws. Whereas lithium disilicate glass-ceramic has a better translucency than alumina and zirconium based ceramic, result from the higher content of glass phase than that two materials. The purpose of this article is to present the information that can guide the practioner in the decision making process about all-ceramic FPDs systems. It can be concluded that the all-ceramic FPDs are seems to be an acceptable clinically prosthodontic treatment according to the short-term studies and the lithium disilicate and alumina-based ceramic materials are acceptable for 3 units anterior FPDs, whereas zirconia-based ceramic are acceptable for 3–5 units anterior and posterior FPDs with 2 pontics. However, further investigation and more clinical long-term follow-up studies are needed.

Background: After tooth extraction, the socket leaves a defect on the alveolar bone. The administration of shell crab-derived hydroxyapatite maintains bone dimensions that are important for achieving successful prosthodontic treatment. Purpose: The aim of the study was to determine the osteogenic properties, such as the number of osteoclasts, osteoblasts and osteocytes, after the application of hydroxyapatite-based shell crab in the post-extraction sockets of Wistar rats. Methods: There were two groups: the control group (K) and the treatment group (T). Wistar rats were randomly divided into control and treatment groups. After tooth extraction, hydroxyapatite gel derived from Portunus pelagicus shells was applied to the tooth sockets of Wistar rats. Observations and calculations of osteoclasts, osteoblasts and osteocytes were carried out on the 14th and 28th days under a light microscope with 400 times magnification. Statistical analysis was performed using one-way ANOVA. Results: There was a significant difference (p<0.05) between the K14 and P14 groups, K28 and P28 groups, K14 and K28 groups, and P14 and P28 groups. The results indicated that there were significant differences between groups of variables. Conclusion: The application of shell crab-derived hydroxyapatite (Portunus pelagicus) was able to decrease the number of osteoclasts and increase the number of osteoblasts and osteocytes.

Background: Complete dentures can improve the quality of life of edentulous patients. The selection of a suitable articulator and an impression technique is important to construct a stable and retentive complete denture with good occlusion. The use of a semiadjustable articulator ensures that the dentures can be constructed such that their movement closely resembles the patient’s physiological movements. The effective suction method can ensure the development of the border seal according to the patient’s anatomical condition. The use of a semi-adjustable articulator along with an effective suction method is expected to provide good results in the construction of a complete denture. Purpose: This report aimed to describe the management of individual complete dentures in the flat mandibular ridge using a semi-adjustable articulator along with an effective suction method. Case: A 69-year-old female patient came with a chief complaint of her old dentures being unusable and wanted new dentures made. The patient’s general condition was good, and the last extraction was done three months prior to the patient’s arrival. The mandibular posterior alveolar ridge showed dextral tapering and sinistral flatness. Case Management: A complete denture with an acrylic base was fabricated using a semi-adjustable articulator along with an effective suction method. Conclusion: Flat ridge case management using a semi-adjustable articulator with an effective suction method can improve complete denture retention and stability.
