Zirconia in dental implants: an overview

Zirconia (Yttria-stabilized Tetragonal Zirconia Polycrystals: Y-TZP) was introduced in dentistry and in orthopedics during the second half of the 1980s, thanks to its outstanding mechanical behavior due to tetragonal-monoclinic phase transformation. In addition, Y-TZP clinical records evidence the excellent biological safety of this hi-tech ceramic. In dentistry, the uses of zirconia are manifold, the main ones being dental implantology (fixtures and abutments), restorative dentistry (CAD-CAM blanks as material for crowns, bridges, FPDs) and more recently full contour zirconia crowns.

So far, a number of ceramic implant systems is on the market, enlarging the number of solutions available for dentists to fulfill their patients’ needs. The scientific literature shows that the osseointegration of zirconia and titanium implants is similar. In addition, ceramic implants are offering advantages over titanium in terms of esthetics and hygienic properties. The concerns of a growing share of the public about sensitization to metals is also contributing to the demand of metal-free devices in dentistry.

This presentation briefly reviews the evolution of ceramics dental implantology, the chemical-physical and mechanical properties of zirconia, the behavior of zirconia in the interaction with the implant environment. In addition, this presentation outlines the development now in progress in ceramic implantology based on new zirconia-based dispersion ceramics, the improvements introduced in the manufacturing processes, new design of implants and on the surface treatments aimed to improve the osseointegration of ceramic devices.

Chapter 1 “Biomaterial Ceramic”

Low temperature degradation as aging of zirconia – does it affect implant performances?

Zirconia exhibits the best mechanical properties of oxide ceramics: this is the consequence of phase transformation toughening, which increases its mechanical resistance. The high strength and toughness of zirconia is associated to an excellent biocompatibility and bone-integration, which makes it an excellent candidate and a credible alternative to titanium. However, it is also the subject of specific attention and controversies among scientists, industrials and clinicians, concerning its long-term stability in-vivo. Due to this propensity to transform, zirconia can also be prone to aging and degradation under some conditions: this has been unfortunately verified in particular cases in vivo with some critical consequences in some biomedical fields. The subject has been treated by a large number of papers, both in-vitro and in-vivo but confusion still exists on the potential impact of aging on implants, in terms of functional performances. In this talk, we will briefly summarize the main aspects of the so-called ‘Low Temperature Degradation’ of zirconia, which stands to a progressive phase transformation of zirconia in presence of water or body fluids. We will then review our current analysis of state-of-the-art dental implants, which shows that current processing technologies, when they are well-controlled, insure a sufficient resistance to aging for prolonged duration. In addition, we will show that simple protocols can allow to assess mechanical reliability and lifetime on a given zirconia dental implant product.

Chapter 2 “Biological Aspects”

Titanium and corrosion – Fact or Vision?

Humans are exposed to different types of particles that can enter the body mainly through inhalation, ingestion and/or the skin. In view of the widespread use of biomaterials in medicine, another potential source of systemic contamination with micro (MPs, >100nm) and /or nanoparticles (NPs, 1-100nm) is the surface of metallic biomedical devices. Titanium is widely used in the manufacture of dental and orthopedic implants due to its excellent biocompatibility. It is a highly reactive metal, and on exposure to air or fluids it rapidly develops a passivating layer of titanium dioxide (TiO2). However, as a result of electrochemical corrosion processes, frictional wear (tribology), or a synergistic combination of the two, ions/particles may be released from metal implants. The combined effect of mechanical, biochemical, and electrochemical factors is known as tribocorrosion.

The side effects caused by titanium ions/ micro- and nanoparticles in biological systems have been ignored mostly, as this metal is widely considered to be inert. Research in human samples conducted by our group has shown the presence of titanium particles in peri-implant tissue around failed human dental implants, in oral mucosa in contact with implant cover screws, in cells exfoliated from peri-implant oral mucosa around titanium dental implants, and in reactive lesions in the peri-implant mucosa. In addition, our studies in experimental animal models demonstrated deposition of titanium micro and nanoparticles and the presence of a tissue response to these particle deposits.

This presentation will address the local and systemic effects of tribocorrosion of titanium, as shown by our studies in experimental animals and human tissues.

Evidence of hard- and soft tissue integration of zirconia

In early pre-clinical and clinical trials in implant history, both titanium and ceramic (alumina) appeared suitable for manufacturing of dental implants. After this initial coexistence, alumina yielded an increasing number of failures due to fracture and aseptic loosening and left clinical use. The demand for metal-free tooth replacement has shown significant growth in the last decade. In this context, zirconia clearly emerges as the material of choice for this purpose. Reports from bench studies, histometric analyses and clinical trials appear correspondingly in the scientific literature. This presentation addresses key questions related to this material, in the perspective of hard- and soft tissue integration. Current scientific data as well as their relationship to clinical reality will be discussed

Chapter 2 “Biological aspects”

Zirconia implants and peri-implant infections
Based on their excellent osseous integration, clinical reliability and scientific documentation, micro-rough titanium implants are currently the gold standard in implant dentistry. However, clinical drawbacks like peri-implant infections, which are among the main reasons for early and late titanium implant failure, have been reported. In recent years, zirconia implants have become a reliable future technology. Evidence-based data have shown that zirconia implants with a micro-rough surface show equal soft and hard tissue integration and similar clinical survival rates compared with established titanium implants. In addition, experimental studies have reported that zirconia shows significantly less bacterial adhesion and significantly reduced ligature-induced peri-implant bone loss compared with titanium. However, although clinical long-term studies have reported promising results, it remains unclear if zirconia shows less affinity for peri-implant infections compared with titanium. This lecture will present current evidence-based experimental and clinical data regarding the microbial colonization, subsequent plaque formation and incidence of peri-implant infections around zirconia and titanium implants.

Chapter 2 “Biological aspects”

Zirconia implant topography changes: Possibilities and risks
A relevant issue in implant biomaterial research is the creation of defined surface properties to better control the target cell-biomaterial interactions. Regarding oral implantology, the impact of biomaterial surface properties on bone tissue response has been recognized already in the early 1980s. With emphasis on these properties, innumerable surface modifications of implant materials have been introduced up till now, all of them aiming at to ensure a long-lasting bone-to-implant interface. With respect to surface topography, there is a wide consensus today that microrough implant surfaces better support osteoblast-triggered hard tissue integration than smooth surfaces. However, with the development of multitude surface modification methods to roughen the ceramic surfaces, implants with similar average surface roughness, but different micro- and nanotopographical properties were produced, provoking different cellular reactions. This suggests that other details of the surface structure can be more determining on cell-biomaterial interaction-derived cell fate than their roughness degree. This lecture will provide an overview of state-of-the-art surface modification techniques of zirconia implants and the resulting topographies as well as of the current knowledge on the link between specific surface topography parameters and the cell response at the tissue-implant interface. The goal is to raise the awareness for the significant role of distinct structural micro- and/or nanoscale features of implants, which arise from the different surface modification techniques, in influencing target cell behavior and thus, essentially contribute to implant tissue integration.

Chapter 3 “Clinical Aspects”

Zirconia implants and clinical long-term results

The current commercial dental implant material of choice is pure titanium. Its properties have been well documented in numerous experimental and clinical applications over the past decades. A major driver, however, for alternatives to titanium in implant dentistry is an ongoing discussion on sensitivities and allergies associated with failure of dental titanium implants. To date, there seems to be no evidence for clinical relevance of this hypothesis. Further potential aesthetic advantages of ceramics over titanium as implant material in the anterior zone and in patients with compromised soft tissue have been used as arguments to justify the search for alternative materials. But here, too, little reliable data are available on the aesthetic outcome of zirconia implants compared to titanium implants. In the presentation potential indications for ceramic implants based on the conclusions of clinical studies and clinical midterm follow ups will be discussed.

From immediate to delayed implant placement with zirconia implants

Dental implants made of titanium and titanium alloys are considered the gold standard in implantology, but recently, questions about biocompatibility, high corrosion, and debatable mechanical properties, came to question their clinical behaviour.

The increasing demand for metal-free dental implants and the development of refined, tougher, and stronger ceramic core materials in recent years has led to the wider use of new, strong all-ceramics systems based on oxide ceramics as an alternative to titanium in implant dentistry. The state of digital art essentially aims at simplifying clinical acts with greater predictability and speed, with a clear benefit to the patient. Digital technology has also allowed the integration of once hard-to-master technologies such as zirconia one-piece implants or the use of pre-fabricated customized abutments. The mechanical part of zirconia implant protocols is undoubtedly important. However, it is in the area of Biology and Physiology to implant that these zirconia technologies make a difference in relation to conventional ones.

In this context, this conference aims to show the pros and cons of ceramic implants in different times of placement, confronting biochemistry, biology, aesthetics and function.

How advances in ceramic implants have benefited my patients and practice

Why are there worldwide more users of bone level implants than of tissue level implants? Think about this questions just a second, why is it so? The answer could be, that bone level implants osseointegrate better than tissue level implants. Do bone level implants osseointegrate better than tissue level Implants? The answer is no, there is enough evidence, that both types of implants have equal success and survival rates. What influences our decision to choose the implant components we do? Our former training, history of implants, referrals, marketing and advertising, pricing, key opinion leaders, evidence data and biology perhaps. But the most important thing should be patients outcome. It is influenced by osseoconductivity, soft tissue reaction, minimized bacterial infection, localized inflammatory front and response and at last, super esthetic. Ceramic implants made of Zirconia have these good biocompatible character to create a satisfied patients outcome. Latest scientific evidence shows less plaque affinity and less peri-implantitis in comparison to titanium, good soft tissue reaction and excellent esthetic results. The natural light transmission of zirconia implants in combination with full ceramic restaurations is outstanding. The clinical consequence of these facts for me is to use modern ceramic implants for esthetical rehabilitations and for patient groups, where I have to avoid plaque accumulation and the danger of peri- implantitis. These are former patients with periodontitis history, which need implants to replace lost teeth. Many clinical examples in my presentation should demonstrate the advantages of ceramic implants and show the clinical implementation of these alternative metal free components in my daily routine.

The step from titanium to zirconium dioxide – if I start on Monday

Change is part of life but only the fittest survive. Without change there is no evolution, and without evolution, degeneration occurs. Standing still is even going backwards… Change is not easy, is often feared and creates uncertainty. Therefor, most people prefer to stick to old trusted solutions, instead of embracing innovations. Medicine, in particular dentistry, is a discipline that is continuously subjected to evolutionary trends. Soon, printed prosthesis and crowns, instead of handmade devices, will be available. Where formerly amalgam was used to fill up cavities, today composites are commonly applied. Since P-I. Brånemark introduced osseointegration in dental medicine, a tremendous evolution took place. Whereas primarily only the full edentulous were treated with complete bridges or overdentures, now solitary implants are the majority of our routine implant cases. Also implants changed dramatically over the years. The morphology of the screws, even as the surface properties were further developed, ceramic abutments were introduced, so was guided surgery. The implant material of choice remained however titanium. The only alternative in the past was aluminium-oxide, a product that was not appropriate as implant material because of its weakness. More recently however, zirconia implants entered the market. This lecture will explain why zirconia implants can and will change the field of oral implantology. Furthermore a strategy on how to introduce ceramic implants in your daily practice next Monday, is presented. Finally, a 5-step plan to increase your market share in (ceramic) implants is proposed.

Options in prosthetic full arch reconstruction with PEEK

Although this high performance polymer material is nothing new in medicine and dentistry it is still missing the broad acceptance in the dental market. This is due to the fact that this plastic material is so different to what we are used to. The first part of the lecture is dedicated to the 10 year clinical results we already have and will explain the real potential and reliability of this material. Polyetheretherketone is sometimes called the steel among plastics due to the unique and outstanding material properties, I will explain. Last but not least it is metal free and biocompatible. This plastic is considered one of the world’s highest performing materials of its kind and many metal parts in industry are being replaced by PEEK. Especially in dentistry this material even provides advantages over metal parts. The second part of the lecture explains how and in which way PEEK can help us to provide definitive metal free full arch rehabilitations in the edentulous jaw with considerable advantages compared to other materials.
