“…In the present case, the patient sought treatment with temporary crowns in teeth 11 and 21, and a Morse taper implant replacing tooth 22. Mangano et al, 2014, stated minimum bone loss and high mechanical stability (NENTWIG, G. H., 2004;DIBART et al, 2005). Given the abutment was well positioned and had correct shape, the gingival contour and the presence of papillae provided an enhanced similarity to the crowns and adjacent teeth.…”

Among the ceramic materials used in dentistry, Zirconia presents the ideal opacity for cases where the clinical challenge is to neutralize the difference in the colors of the substrates. The "ceramic steel", so called by some authors, guarantees to Zirconia resistance and hardness similar to a metal, but with aesthetic advantages superior to the metal-ceramic restorations, which can exhibit exposure of the metal band over time. This article describes a complex rehabilitation treatment involving dental elements with different substrates: 11 -vital tooth with large crown damage; 21 -endodontically treated tooth and cast metal core; 22 -Morse taper implant. The selection of a completely zirconia-based ceramic system allowed masking the different conditions of substrates, so achieving the esthetic expectations. Moreover, considering the patient's high smile line, excellent gingival esthetics was obtained with an internal connection Morse taper implant associated with an individualized anatomic abutment.

“…What is more, relatively high survival rates (98.2%) were seen involving 275 DENTSPLY Friadent ANKYLOS® implants loaded prosthetically in the form of a single crown, during an 8-year follow-up period [2]. Beyond the aforementioned, in one of his works, Nentwig [12] rated the survival of 5439 DENTSPLY Friadent ANKYLOS® implants, with an average prosthetic restoration loading time, as equal to 56.8 months. In the case of a single tooth, the survival rate was 98.7%, while the survival rate with a prosthetic supplement restoring missing posterior teeth was 97.9%.…”

“…The survival of the implants involves the following factors as well: the experience of the implantology center (multicenter study) [1,6], the dimensions of the implants (length, diameter) [19], the use of single or combined implants in the prosthetic phase [12], the place of implanting [6,7] and the habit of smoking [8,14]. At the same time, other publications have not demonstrated the effect of the above-mentioned and other factors on the survival of implants [4,5,7,9,13,18].…”

The aim of the study was to evaluate the survival of implants with different implantabutment connection systems, in patients who had two kinds of implants implanted. In total, 240 implants were implanted -91 implants with conical abutment Morse connection, and 149 with an internal hexagonal connection. During the follow-up period of 3 years and 10 months, the percentage of lost implants with a conical implant-abutment connection was 1.1%. Regarding the implants with hexagonal implant-abutment connection, this figure was 0.7%. Our work shows that there is a need for further research on the survival of dental implants. In this, the influence of other factors should be explored that are related both to the specific implant treatment, as well as to socio-demographic factors.

“…1 For a Morse taper implant, the friction at the tapered connection results in a high contact pressure and frictional resistance, causing limited strain that must be absorbed by the abutment screw thread, which differs from the butt joint where the screw alone keeps the abutment connected to the implant. 2,3 This mechanism provides excellent biological and mechanical stability and unusual prosthetic versatility; 4 in fact, the prosthetic versatility is similar to that of a hexagonal implant. A total of 2,549 Morse taper connection implants that were placed in 893 patients were evaluated, and the incidence of abutment loosening was 0.37% for Declaration of Interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”

Strain analysis of different diameter Morse taper implants under overloading compressive conditions

et al. 2015

The aim of this study was to evaluate the amount of deformation from compression caused by different diameters of Morse taper implants and the residual deformation after load removal. Thirty Morse taper implants lacking external threads were divided into 3 groups (n = 10) according to their diameter as follows: 3.5 mm, 4.0 mm and 5.0 mm. Two-piece abutments were fixed into the implants, and the samples were subjected to compressive axial loading up to 1500 N of force. During the test, one strain gauge remained fixed to the cervical portion of each implant to measure the strain variation. The strain values were recorded at two different time points: at the maximum load (1500 N) and 60 seconds after load removal. To calculate the strain at the implant/abutment interface, a mathematical formula was applied. Data were analyzed using a one-way Anova and Tukey's test (α = 0.05). The 5.0 mm diameter implant showed a significantly lower strain (650.5 μS ± 170.0) than the 4.0 mm group (1170.2 μS ± 374.7) and the 3.5 mm group (1388.1 μS ± 326.6) (p < 0.001), regardless of the load presence. The strain values decreased by approximately 50% after removal of the load, regardless of the implant diameter. The 5.0 mm implant showed a significantly lower strain at the implant/abutment interface (943.4 μS ± 504.5) than the 4.0 mm group (1057.4 μS ± 681.3) and the 3.5 mm group (1159.6 μS ± 425.9) (p < 0.001). According to the results of this study, the diameter influenced the strain around the internal and external walls of the cervical region of Morse taper implants; all diameters demonstrated clinically acceptable values of strain.
