Influence of bone insertion level of the implant on the fracture strength of different connection designs: an in vitro study

Abstract

When implants are used in areas where there is a possibility of bone loss, the selection of a connection type is an important consideration for the longevity of the system.

Importance of Crown Height Ratios in Dental Implants on the Fracture Strength of Different Connection Designs: An In Vitro Study

“…The implant diameter relative to the dimension of the supporting bone is critical for successful treatment. 21 The average maximum bite force for adults in the premolar and molar regions is 789 N for men and 596 N for women. 22 In our study, fracture strength after static loading of the specimens was significantly higher for all groups when the CHR was 8 mm.…”

Immediate loading over lower prosthesis in edentulous mandibles: comparison between two types of prosthetic connection

“…Those factors directly affect the surrounding bone tissue, causing resorption and even leading to the loss of the implant. Some studies show that the internal connections have a smaller space between the implant and the abutment and thus lower risk of biological and mechanical problems 7,[16][17][18] . As in this study, in order to determine which implant system causes less damage to the perimplant tissues, some studies compared the different types of prosthetic connections 7,19 .…”

“…The internal connections, especially the Morse cone, have shown better performance over the external connections in some experimental studies 1,3,10,[17][18] . Goiato et al 3 , showed better distribution of loads on implants with Morse cone connections when compared to external hexagon connections.…”

“…Assuming that the type of prosthetic connection interferes with the dispersion of loads around the implant, it also influences the perimplant bone loss. Therefore, several authors evaluate the perimplant bone loss in different types of prosthetic connections 1,3,[7][8][17][18] . In this study, the largest amount of bone loss was observed for the external hexagon group in comparison to the Morse cone group, but without statistically significant difference between them.…”

Distribuição das tensões promovidas por implantes cone Morse inseridos em diferentes níveis ósseos: análise fotoelástica e método dos elementos finitos

“…Pode-se justificar a discrepância de resultados nos modelos com recobrimento da plataforma do implante (AB-C), verificados no estudo fotoelástico prévio de Gehrke et al (2014) Uma inserção mais profunda proporciona uma resistência superior às forças externas, particularmente àquelas envolvidas com a reposição de implantes na região de molar (Gehrke et al, 2014). Apesar disso excelentes resultados em estudos de larga escala foram obtidos inserindo os implantes ao nível da crista (Mangano et al, 2009(Mangano et al, , 2011.…”
