“…Regarding all-on-four treatment concept, the distal implants were placed with angulation in order to achieve many beneficial goals such as avoiding the interference with the vital structures such as mental foramen or maxillary sinus, allowing the operator to use longer implant with more anchorage with bone and shortening the length of the cantilever arm of the framework 1,17 .…”

Objectives: This study evaluated the effect of different angulations of posterior implants in all-on-four treatment concept when using glass fiber reinforced composite (GFRC) framework in comparison to titanium framework material.Materials and methods: Three-dimensional finite element model of completely edentulous mandible was simulated using cone beam computed tomography. Six different models were created and restored according to all-on-four treatment concept. The six models were created by using three different angulations of the posterior dental implants; 15°, 30° and 45° and using two different framework materials; titanium (Ti) framework and glass fiber reinforced composite (GFRC) framework. At the end of the cantilever part of the frame work, unilateral load of 250N were applied and the resultant von Mises stresses at the implant/crystal bone interface were calculated. Results:The Ti framework produced lower stresses in comparison with GFRC framework within the same distal implant angulation. Moreover, increasing the tilting of the posterior dental implant developed more stresses at the implant/crystal bone interface. Conclusion:Using rigid framework material with decreasing the tilting of posterior dental implant angulation transmit less stresses to the implant/crystal bone interface.

“…It provides results that can be compared and describes the test method, including test instrument characteristics, geometry, sample holder, load application, test environment, load frequency, wave shape, and procedural characteristics [10]. The ISO 14801 standard uses the "All on four" technique, where two implants are placed vertically on the anterior region and two on the non-edentulous region, with an inclination angle of 30° to 45° degrees [25]. This example of a healing abutment, whose surface components often vary in various oral cavity conditions, serves as the basis for this study.…”

Dental implants are an alternative dental treatment that has been developed with one of the chosen materials, called Ti-6Al-4V. The pH environment in the oral cavity is expected not to affect the Ti-6Al-4V implant’s durability. The aim of this research was to analyze the change in compressive strength of the Ti-6Al-4V implant after dynamic and immersion tests with artificial saliva at pH 8.0. The method that we used in this research is laboratory experimental and analytic research was conducted with 27 Ti- 6Al-4V implant samples, which were classified into three groups as research subjects. Each group consists of 9 samples, including those with no treatment (UT), aquades solution (DW), and artificial saliva with a pH of 8.0 (AS). In the negative control group, the samples were treated dynamically in accordance with the ISO 14801 standard, while the samples in the positive control group were not treated. Samples from the treatment group were subjected to a dynamic test in accordance with ISO 14801 standards while being immersed in artificial saliva with a pH of 8.0. Thereafter, a compression test was conducted on the three sample groups. A one- way ANOVA test was used to analyze the comparison of treatment results. The result for this research is the immersed Ti-6Al-4V implant in artificial saliva and dynamic testing with a stress of 50 N, 2 million load cycles, and a frequency of 12 Hz do not significantly impact the compressive strength of each Ti-6Al- 4V sample. In Conclusion, the dynamic treatment along with the immersion test on artificial saliva at pH of 8.0 seemed to have no effect on the compressive strength of each sample.
