“…There are many examples of clinical problems that went through from a qualitative assessment to a quantitative evaluation thanks to their modelling [1], [2], furthermore, the application of classical experimental methods of structural analysis to the evaluation of the efficacy of procedures or surgical techniques [3]- [7] or to the evaluation of the mechanical characteristics of the materials used at different scales of investigation [8]- [10] pushed the dental science forward.…”

Bond strength between the dentin and the restorative resins is deeply dependent on the nature of their interface. Resins impregnate dentin, which is rich in collagen fibers. This in vitro study aimed to evaluate the effect of collagen carbodiimide cross linker agent (EDC) on the mechanical properties of the adhesive interface in endodontically treated teeth. Twenty upper premolar teeth were selected and divided into two groups according to the dentin pretreatment procedures: no EDC application (group A) and EDC application (group B). Three typical zones, i.e. the dentin, the radicular hybrid layer and the resin, were analyzed using a Nanoindenter XP equipped with a diamond Berkovich indenter. The input curve was characterized by loading and unloading phases with a strain rate value of 0.1 s -1 and, an intermediate dumbbell phase of 30 s. The maximum indentation depth was set to be 200 nm. The load-displacement curves were analyzed by using the "Oliver and Pharr" method. The mean values of nanoindentation modulus were determined for the dentin, the radicular hybrid layer and the resin for both the samples with and without crosslinker. In general, the application of EDC was found to modify the mechanical properties of the radicular hybrid layer. The mechanical properties of the radicular hybrid layer could be related to the efficient infiltration of the adhesive systems and collagen crosslinker through dentin.

“…It is speculated that variations in implant surface characteristics and performance of osteotomy and implant placement by multiple operators may yield varying results in terms of ISQ measurement. This should be considered since previous studies compared the implant initial stability for tapered with cylindrical designed implants placed in vitro in bone blocks by investigators with varying skill and showed that the experienced clinicians achieved higher ISQ values with tapered‐implants in artificial bone blocks with varying densities. However, from a clinical perspective, it is hypothesized that narrow diameter implants when placed in dense bone (such as in the anterior mandible) remain functionally stable and demonstrate high ISQ values.…”

Background There are no studies that have assessed the implant stability quotient (ISQ) values of narrow diameter implants placed in artificial dense bone blocks at varying drilling speeds (DSs). Purpose The aim of the present in vitro experiment was to compare the performance of OSSTELL and Penguin devices to evaluate implant stability at DSs of 800 and 2000 rpm. Materials and Methods A total of 360 osteotomies were created in dense artificial bone blocks at DSs of 800 and 2000 rpm. Dental implants from three manufacturers (group‐1: NobelActive implants, Nobel Biocare, Yorba Linda, California; group‐2: Zimmer, Eztetic‐Zimmer implants, Zimmer Biomet Dental, Palm Beach Gardens, Florida; and group‐3: Astra Tech implant system, Dentsply Sirona, York, Pennsylvania) were randomly placed in these osteotomies using an insertion torque of 15 Ncm (60 implants/group). Implant stability in all bone blocks immediately following implant placement was evaluated using the OSSTELL and Penguin devices. ISQ values were presented as means ± SD. Statistical significance was set at P < .05. Results There was no significant difference in the ISQ values obtained from the OSSTELL and Penguin devices for implants in groups 1, 2, and 3. There was no significant difference when ISQ values obtained from the OSSTELL device were compared with the Penguin device for narrow diameter dental implants placed in dense bone blocks with osteotomies performed at 800 and 2000 rpm. ISQ values showed statistically significant higher values for OSSTELL compared to Penguin device. Conclusion The OSSTELL and Penguin devices are reliable for the assessment of implant stability in dense artificial bone. Implant design and site‐DS does not seem to have a significant impact of implant stability in artificial dense bone blocks.

“…Histolojik analiz kemik-implant kontak miktarının hesaplanması için implant çevresindeki kemikten örnek alınmasını gerektirdiğinden oldukça invaziv bir yöntemdir. Bu nedenle, osseointegrasyon seviyesinin belirlenmesinde yüksek doğruluk payı olmasına rağmen klinik olmayan çalışmalarda ve deneylerde kullanılabilir [13].…”

Öz Osseointegrasyon, protezi desteklemek için temel oluşturabilecek bir implant gövdesine doğrudan bir kemik ankrajının olması olarak tanımlanır. İmplant stabilitesi, kemik ve implant yüzeyi arasında direk yapısal ve fonksiyonel bağlantı olan osseointegrasyon için önemli rol oynamaktadır. İmplant stabilitesi, primer ve sekonder stabilite olmak üzere 2 aşamada meydana gelmektedir. Primer stabilite, kemik ile mekanik bağlanma sonucu ortaya çıkarken; sekonder stabilite, kemik rejenerasyonu ve remodelasyonu ile ortaya çıkan biyolojik stabilitedir. Başarılı ve sürdürülebilir implant stabilitesi istenen bir klinik sonuçtur. Bu nedenle implant stabilitesi ölçüm yöntemleri, implant başarısının değerlendirilmesi bakımından oldukça önemlidir. İmplant stabilitesini değerlendirmek amacı ile çeşitli yöntemler kullanılmaktadır. Bu derlemede, literatürdeki bilgiler ışığında, kullanılan yöntemlerin avantaj ve dezavantajları birbirleriyle karşılaştırılarak klinik kullanımları hakkında detaylı bilgi verilmesi amaçlanmıştır. AbstractOsseointegration is defined as the presence of a bone anchorage directly to an implant body, which may form the basis for supporting the prosthesis. Implant stability plays an important role in osseointegration, a direct structural and functional connection between bone and implant surface. Implant stability occurs in two stages as primary and secondary stability. Primary stability was mostly caused by mechanical attachment with cortical bone; secondary stability offers biological stability through bone regeneration and remodeling. Successful and sustainable implant stability is a successful clinical outcome. Therefore, the methods of measuring the stability of the implant are very important for the evaluation of implant success. Various methods are used to evaluate implant stability. In this review, in the light of the information in the literature, it is aimed to give detailed information about the clinical uses of the methods by comparing the advantages and disadvantages of the methods. 77 Primer stabiliteyi değerlendirmenin bir yöntemi de hekimin algısıdır. Bu genellikle yerleştirme sırasında implantın kesme direncine ve oturma momentine dayanır. İmplant oturduğunda ani durma hissi ile iyi stabilite algısı oluşur. Ancak bu yöntem yalnızca implantın yerleştirilmesi aşamasında kullanılabilir [11]. Perküsyon TestiPerküsyon testi, osseointegrasyon seviyesini tahmin etmek için kullanılabilecek en basit yöntemlerden biridir [5]. Bu yöntem, metal bir aletle vurma sonucu duyulan sese dayanır.
