“…According to results to the present study, the tapered implant body (Model B) decreased stresses in both cortical and trabecular bone compared to the cylindric design (Model A). These results are in agreement with previously published data [18,19,[26][27][28][29], indicating that tapered implants could reduce peak stress in both cortical and trabecular bone. Stress analysis was performed for various implant designs by Li Huang et al [29] using three-dimensional finite element analysis approaches.…”

“…Therefore, in the process of designing dental implants, particular attention must be paid to the distribution of stress on the neck area of the implant. Some studies have highlighted that the implant neck designs can influence the level of stress for the peri-implant cortical bone avoiding peri-implant implant bone loss [19][20][21][22][23]. Misch and Bidez [21] reported that an implant collar angled by more than 20 degrees with a surface texture designed to increase bony contact might impose slight beneficial compressive and tensile components to the contiguous compact bone and decrease the risk of peri-implant bone loss.…”

Dental implant macro- and micro-shape should be designed to maximize the delivery of optimal favorable stresses in the surrounding bone region. The present study aimed to evaluate the stress distribution in cortical and cancellous bone surrounding two models of dental implants with the same diameter and length (4.0 × 11 mm) and different implant/neck design and thread patterns. Sample A was a standard cylindric implant with cylindric neck and V-shaped threads, and sample B was a new conical implant with reverse conical neck and with “nest shape” thread design, optimized for the favorable stress distribution in the peri-implant marginal bone region. Materials and methods: The three-dimensional model was composed of trabecular and cortical bone corresponding to the first premolar mandibular region. The response to static forces on the samples A and B were compared by finite element analysis (FEA) using an axial load of 100 N and an oblique load of 223.6 N (resulting from a vertical load of 100 N and a horizontal load of 200 N). Results: Both samples provided acceptable results under loadings, but the model B implant design showed lower strain values than the model A implant design, especially in cortical bone surrounding the neck region of the implant. Conclusions: Within the limitation of the present study, analyses suggest that the new dental implant design may minimize the transfer of stress to the peri-implant cortical bone.

“…In contrast, the decrease in the depth of the fillet allows for easier insertion into the denser bone without the need for tapping [41]. The results obtained regarding this localized study of the peri-crestal zone were extremely interesting [42,43]. Firstly, both implants generated significantly lower stress distributions in the peri-crestal area than the yield stress of the material constituting the abutment (the maximum stress developed in this area was 100 MPa in the face of a yield stress of 860 Mpa Ti6Al4V).…”

The aim of biomechanics applied to implantology is to determine the deformative and tensional states by solving the equilibrium equations within the mandibular bone and the osseointegrated implant to ensure its stability and improve the success rate. The finite element method is a powerful numerical technique that uses computing power to derive approximate solutions for the analysis of components with very complex geometry, loads, materials, and especially the biomechanical problems analysis, which is challenging to find in vivo or in vitro. This study performs a complete FEA survey on 3 implants Cono-in with 3 different diameters 3.4 mm, 4.5 mm, and 5.2 mm with abutments inclined to 15° and evaluates the tensions that are generated in the system as a result of the application of chewing loads. In this study, the extent of the stresses developed in the peri-crestal zone of the implants with the variation of the occlusal overstress acting on them was also evaluated. Autodesk Inventor Nastran Software was used to perform this type of localized finite element analysis; With this type of analysis, it was possible to analyze the peri-crestal area of the implant more precisely through a more accurate reconstruction of the mesh element, which allowed us to solve the FEA solution mathematically. The results showed how the application of the inclined load with respect to the vertical load on a larger diameter system leads to an increase in stress.

Bulgular: Von Mises stres değerleri tüm modellerde 30° açılı yüklemede artmıştır. Von Mises stres değerleri, her iki yükleme simülasyonunda titanyum vidada zirkonyuma göre önemli ölçüde azaldı.Sonuç: Isırma kuvveti yüksek olan hastalarda zirkonyum fizyolojik stres limit değerleri aşılmamıştır. Bruksizm hastalarında zirkon bağlantı vidası kullanılmasında sakınca yoktur.
