“…Salah satu contoh material keramik yang dapat dijadikan sebagai bahan kajian adalah ZrO 2 [13][14][15]. Bahan ini sering digunakan sebagai material solid oxide fuel cell (SOFC) [16][17][18], penggunaan dalam bidang medis [19,20], bahan dielektrik [7,21], proteksi material dari korosi dan oksidasi logam [22][23][24] serta dapat digunakan sebagai matriks kolom generator radioisotop [25].…”

ZrO2 merupakan bahan keramik yang memiliki banyak struktur (Polimorpi). Struktur yang dimiliki oleh ZrO2 terdiri dari struktur monoklinik yang stabil pada temperatur ruang, tetragonal dan kubik. Metode penelitian pada penulisan jurnal ini menggunakan teknik review dari beberapa peneliti yang telah melakukan kajian secara intensif dengan berbagai variasi metode yang telah dilakukan. Selain dari itu, penyusunan jurnal ini dilengkapi dengan penggunaan software Vesta yang terintegrasi dengan data-data kristalografi yang tersedia pada laman crystallography.net/cod/ sehigga dapat memberikan simulasi atas pemberian dopan yang diberikan pada ZrO2. Berdasarkan kajian yang telah dilakukan, penambahan variasi dopan yang diberikan pada ZrO2 mengakibatkan ZrO2 kubik dan tetragonal stabil pada temperatur ruang dan terjadi perubahan nilai konduktivitas listrik akibat adanya kehadiran vakansi oksigen yang terbentuk dari adanya pemberian dopan yang diberkan. Perubahan nilai konduktivitas listrik tergantung dari jenis dan konsentrasi dopan yang diberikan.

“…As a promising prosthodontic material, zirconia exhibits excellent biocompatibility while possessing outstanding mechanical properties, such as mechanical strength, wear resistance, and thermal stability. It also has a unique phenomenon known as “transformation toughening”, which helps to halt crack propagation [ 1 ]. A zirconia crown has several advantages, such as high flexural strength (1020 MPa) and a low tendency to fracture (~9 MPa⋅m − 1/2 ) [ 2 ]; however, it also has the disadvantage of excessive hardness (~1300 Hv) compared to enamel, which leads to an abrading effect on the opposing natural tooth if its surface is not fully polished [ 3 ].…”

The computer-aided design/computer-aided manufacturing (CAD/CAM) fabrication technique has become one of the hottest topics in the dental field. This technology can be applied to fixed partial dentures, removable dentures, and implant prostheses. This study aimed to evaluate the feasibility of NaCaPO4-blended zirconia as a new CAD/CAM material. Eleven different proportional samples of zirconia and NaCaPO4 (xZyN) were prepared and characterized by X-ray diffractometry (XRD) and Vickers microhardness, and the milling property of these new samples was tested via a digital optical microscope. After calcination at 950 °C for 4 h, XRD results showed that the intensity of tetragonal ZrO2 gradually decreased with an increase in the content of NaCaPO4. Furthermore, with the increase in NaCaPO4 content, the sintering became more obvious, which improved the densification of the sintered body and reduced its porosity. Specimens went through milling by a computer numerical control (CNC) machine, and the marginal integrity revealed that being sintered at 1350 °C was better than being sintered at 950 °C. Moreover, 7Z3N showed better marginal fit than that of 6Z4N among thirty-six samples when sintered at 1350 °C (p < 0.05). The milling test results revealed that 7Z3N could be a new CAD/CAM material for dental restoration use in the future.

“…It has been used with the introduction of zirconia as a selfrepairing to avoid crack propagation (6). Studies reported that the processing of zirconium is becoming very popular because of its high esthetic properties and biocompatibility, in addition to its low plaque sensitivity, its high mechanical resistances compared with conventional metals make it a material of choice (7,8) . Polyetheretherketone (PEEK) is a thermoplastic resin that has been for many years used dentistry and medicine, offering a special combination of mechanical and physical properties due to its unique structure.…”

Purpose: This study aimed to evaluate the retention of single implant mandibular overdenture using different single crown coping materials. Materials and Methods: Clear acrylic resin mandibular cast was fabricated with single implant located in the mid-line of the cast. The cast with the implant was scanned for designing of nine copings of different materials using computer aided design computer aided manufacture CAD/ CAM and according to material used for copings fabrication, models were categorized as follow: Poly etherether ketone (PEEK) group, Zirconium dioxide (ZrO2) group, hybrid composite resin coping group. Nine identical mandibular complete overdentures were constructed, tensile force for removing overdenture with copings was then recorded. Results: Comparison of recorded tensile strength results showed a significant difference among groups where the highest retention was recorded with Zirconia group, followed by PEEK and the lowest retention results were noted with Hybrid composite resin. Conclusion: Within the limitation of this in vitro study, it could be concluded that single crown that fabricated from ZrO2 for supporting implant supported overdenture showed better retention results in comparison to PEEK a hybrid composite one.
