Yeni bir cam hibrid restoratif materyalin geniş ve derin 2. sınıf preparasyonlarda 18 ay sonundaki klinik performansını, rezin kompozit ile karşılaştırarak değerlendirmektir. Gereç ve Yöntemler: Otuz yedi hastada proksimal genişliği kasp tepelerinden 1-1,5 mm uzaklıkta olan 108 2. sınıf çürük lezyonu cam hibrid restoratif materyal (EQUIA Forte, GC, Tokyo, Japonya) veya selektif pürüzlendirme ile kombine mikro-hibrid rezin kompozit (G-aenial Posterior, GC, Tokyo, Japonya) kullanılarak iki diş hekimi tarafından üretici talimatlarına göre restore edildi. Restorasyonlar çalışma grubunda yer alan diğer 2 bağımsız gözlemci tarafından uygulandıktan 1 hafta sonra (başlangıç), 6, 12 ve 18. aylarda modifiye USPHS kriterlerine göre değerlendirildi. Tüm kontrol randevularında her 2 gruptan rastgele seçilen bir restorasyon örneğinden negatif replikalar hazırlanarak taramalı elektron mikroskobu (SEM) ile restorasyonların yüzey özellikleri incelendi. Veriler istatistiksel olarak analiz edildi. Bulgular: On sekiz ay sonunda, 32 (kontrollere gelme oranı: %86,5) hastada 90 restorasyon değerlendirildi. 4 cam hibrid restorasyon; 3'ü tamamen düşme ve 1'i proksimal bölgesinde oluşan kırıktan dolayı 12. ayda kaybedildi. Sadece 6 cam hibrid restorasyon başlangıçta, 6, 12 ve 18. aylarda renk açısından bravo olarak skorlandırıldı (p<0,05). İki restoratif materyal arasında diğer değerlendirme kriterleri yönünden anlamlı farklılıklar görülmedi (p>0,05). On sekizinci ay kontrolünde yapılan SEM incelemelerinde her iki restoratif materyal kabul edilebilir yüzey ve kenar uyumu özellikleri gösterdi. Sonuç: Cam hibrid restorasyonlar istatistiksel olarak anlamlı renk uyumsuzluğu göstermesine rağmen, her iki restoratif materyal 18 ay sonra geniş 2. sınıf preparasyonların restorasyonunda başarılı performans gösterdi. Anah tar Ke li me ler: Kompozit rezin; cam iyonomer; 2. sınıf preparasyon; klinik performans ABS TRACT Objective: To evaluate the clinical performance of a glass hybrid restorative compared to a resin composite in the restoration of large and deep class 2 preparations after 18 months. Material and Methods: A total of 108 extended size-with the width of the proximal box not interfering with the peak of the cusps and the proximal box in occlusion-class II lesions in 37 patients were either restored with a glass hybrid restorative (EQUIA Forte, GC, Tokyo, Japan), or with a micro-hybrid composite resin (G-aenial Posterior, GC, Tokyo, Japan) in combination with selective etching by two experienced operators according to the manufacturer's instructions. Two independent examiners evaluated the restorations at baseline and 6-, 12-and 18-month recalls according to the modified USPHS criteria. Negative replicas at each recall were observed under scanning electron microscopy (SEM) to examine surface characteristics. Data were analyzed statistically. Results: After 18 months, 90 restorations were evaluated in 32 (recall rate: 86.5%) patients. Four glass hybrid restorations were missing; 3 were due to bulk and 1 was due to proximal fracture at 12 mo...

Protetička restauracija pojedinačnog zuba kirurškim produljenjem krune, konzervativnom terapijom i litijevim disilikatnim nadomjestkom proizvedenim CAD-CAM tehnologijom: prikaz slučaja UvodRestauracija znatno oštećenog zuba često zahtijeva interdisciplinarni pristup. Na primjer, od kliničara se može zahtijevati rekonstrukcija estetike i funkcije gornjeg pretkutnjaka, no pritom estetski zahtjevi i žvačno opterećenje često utječu na izbor postupaka i materijala, pa čak i na opću prognozu zuba.U ovom slučaju nekoliko je čimbenika o kojima treba voditi računa -to su položaj i veličina kaviteta, potreba za en-Abstract Objective. The restorative treatment of a decayed, non-vital upper premolar often requires an interdisciplinary approach. Esthetics and the entity of the masticatory loads are usually affecting the choice of procedures and materials. A conservative treatment in a case with esthetic needs and functional requirements is investigated in this case report. Materials and methods. A case of a 45-yearold woman with a severely decayed upper premolar is presented. The tooth has been previously treated in an emergency department with a provisional endodontic medication, but a further treatment has been then performed. The tooth was painful at the moment of the visit and the carious lesion appeared to invade the subgingival level. A surgical-conservative approach has been selected involving crown lengthening, endodontic treatment and a prosthetic crown with a monolithic Lithium-Silicate. Results. The rehabilitative process required 3 months, including maturation times after surgery and the placement of the provisional crown. The patient claimed to be both esthetically and functionally satisfied with the restoration. Conclusion. A conservative treatment of a severely involved tooth requires a critical evaluation of the remaining structures and a precise selection of the restorative materials. A monolithic crown could represent an ideal solution for restoring an upper premolar requiring esthetics and solid function, but the choice of a high translucent, easily polishable and possibly even chair-side prosthetic material might be an appreciable added value for clinicians.

“…(5) In another six-year clinical study, the authors evaluated resin-reinforced glass ionomers in terms of their clinical performance and suggested that their performance is acceptable concerning posterior restorations. (6) These new developments alongside the introduction of a whole new generation of glass ionomers by manufacturers warrant further investigation on the application and survival of such materials in the clinic.…”

Background and Aim:Although the physical properties of modern glass ionomers have been extensively reported, few studies have examined how these parameters change with age. This experimental study aimed to investigate the effect of aging on the compressive strength of resin-reinforced glass ionomers. Materials and Methods: Two glass ionomers (Fuji IX GP Fast, GC, Japan, and Ketac Universal, 3M, USA) and one composite resin (control; Filtek P60, 3M, USA) were chosen for this study. Both glass ionomers were encapsulated and mixed using an amalgamator and were applied using an appropriate applicator. Forty cylindrical (4×6 mm2) samples were made of each material and subsequently incubated at 37°C with 95±5% humidity. Twenty samples from each material were then randomly selected to undergo aging in a thermocycling machine using 1000 cycles (between 5-55°C). The compressive strength of the samples was then measured using a universal testing machine. One-way analysis of variance (ANOVA) and post-hoc Tuckey's test were used for data analysis. Results: The aging process (thermocycling) caused a significant increase in the compressive strength of all three materials. Overall, Ketac Universal displayed higher compressive strength with an average value of 271.1120±15.4387 MPa and 248.6910±15.10716 MPa with and without aging, respectively, compared to Fuji IX GP and Filtek P60. Conclusion: The aging process increases the compressive strength of glass ionomers and composites; however, even with aging, modern glass ionomers still struggle to achieve compressive strength values close to those feasible with composite resin. It is therefore essential to use these materials in non-stress-bearing areas.
