Aim. It’s common that revision arthroplasty of the large joints demands replacing of bone defects of irregular geometrical shapes and simultaneous restoring of support ability and ability to integrate surrounding muscular and tendinous structures into an implant that is required for a complete restoration of joint function.The purpose.To experimentally study the process of integration for muscular and bone tissue as well as tendinous and ligamentous structures into porous titanium materials.Material and methods. During in vivo experiment the authors created a standardized bone defect in 6 rabbits of chinchilla breed at the point of patella ligament attachment as well as a delamination area of muscular tissue in latissimus dorsi. Both knee joints and both latissimus dorsi were used in each animal. Study group included titanium implants with three-dimensional mesh structure. Control group — solid titanium implants with standard porosity. Titanium implants were produced by additive technologies with preliminary prototyping. The porosity corresponded to trabecular metal, striations — 0.45, pores size —100–200 microns. Study and control components were implanted in the identical conditions into the corresponding anatomical sites. Postoperative AP and lateral roentgenograms of knee joints were performed for all animals. Morphological research was conducted on day 60 after the implantation and strength properties were studied at day 90 after the implantation.Results.The authors observed bony ingrowth into implant pores with minimal volume of fibrous tissue, a distinct connective integration was reported represented by a dense fibrous tissue in the pores of components implanted into the muscular tissue. Testing of fixation strength of the study implants demonstrated a clearly superior strength of soft and bone tissue integration into the experimental mesh implants produced using additive technologies.

This study focuses on new technologies for the production of medical implants using a combination of robotics and microplasma coatings. This involves robot assisted microplasma spraying (MPS) of a multilayer surface structure on a biomedical implant. The robot motion design provides a consistent and customised plasma coating operation. Based on the analytical model results, certain spraying modes were chosen to form the optimised composition and structure of the titanium/hydroxyapatite (HA) multilayer coatings. It is desirable that the Ti coated lower layer offer a dense layer to provide the implant with suitable structural integrity and the Ti porous layer and HA top layer present biocompatible layers which are suitable for implant and tissue integration. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to analyse the structure of the coatings. The new robot assisted MPS technique resulting from this research provides a promising solution for medical implant technology.

Abstract Background Fracture of an implant is a quite rare event but represents an important opportunity to evaluate the peri-implant bone tissue response to implant overload in human beings. This study aimed to evaluate bone tissue around three fractured titanium implants retrieved from a human maxilla, by histomorphometric and birefringence analyses. Case report For this, the implants and the surrounding bone were removed after having been united to a tooth in function for 45 months, by a 4-mm internal diameter trephine bur, following an undecalcified section was obtained. The results showed a rate of 77.3% of bone-to-implant contact (BIC) and 80.3% of bone area filling within the limits of the implant threads. Under circularly polarized light microscopy investigation, the amount of the transverse collagen fibers was of 48.11%, and the amount of the longitudinal collagen fibers was of 51.89%. Conclusion Within the limitation of this study, the possible cause of the implant fracture could be the association of overload, inadequate implant diameter, and fragile internal hexagon connection.

Abstract Purpose of Review The goal of the present review is to update the reader on the scientific background of zirconia ceramic implants. Clinical investigations using zirconia ceramic implants over the last couple of years have brought up some new developments and questions. Can we be confident in placing zirconia ceramic implants given the recently published data? Is there a difference in the application of one- and two-piece implants? Recent Findings Systematic reviews on preclinical investigations of zirconia implants revealed that one-piece zirconia implants (> 4 mm) are sufficiently stable for clinical use. The same is true for some clinically available two-piece implant systems. Osseointegration and soft tissue integration are, according to the reviews, similar between titanium and zirconia implants with similar surface topographies. Regarding the clinical outcome, a meta-review exists evaluating systematic reviews. The findings of the systematic reviews and the meta-review are that there are good short-term clinical results for one-piece zirconia implants. However, the data for two-piece implants is not robust. Summary In certain applications (single tooth restorations and small bridges), the results of zirconia implants are comparable with titanium implants in short-term studies. Some mid-term investigations support the short-term results. However, according to the current scientific data available, zirconia implants cannot yet be considered an alternative to titanium implants because there are many areas where there is a lack of clinical studies on zirconia implants. Currently, they are an addendum to the titanium implant armamentarium for situations where they are useful (patient request, known hypersensitivity to titanium, or questions of esthetics when titanium might appear inappropriate for a certain situation/condition), but long-term studies are needed. Without a doubt, there is a need for two-piece zirconia implants, but limited research exists to support their clinical use at the moment.
