50 years of implant dentistry - the problems and challenges: past, present and future

Osseointegration was discovered 50 years ago and the first patient was treated in 1965. After a considerably active academic debate, osseointegration was finally accepted as a reliable concept for treating patients with oral implants around 1980. Since then indications have widened and clinical results gradually improved, particularly after the introduction of new, moderately rough surfaces some 10-15 years ago. In a recent overview, the first 9 clinical papers of such new implants,  followed up for 10 years or more, verified CSR rates of 95% or more with ongoing problems of peri-implantitis limited to 0.88% of about 1.800 implants. However, as agreed at a recent consensus meeting in 2012, the precise magnitude of problematic implants with bone resorption may vary depending on the type of implant, clinical skills of the doctor and status of the patient. For example, patients who are smoking and suffering from compromised bone beds may, particularly if treated by poorly trained clinicians, end up in much greater magnitude of problems in form of implant failure or peri-implantitis than figures quoted above. 

Learning Objectives

  • To set the scene for the whole congress
  • To give a brief history of the journey of osseointegration from the early days of discovery to the current state of development with special reference to implant geometry, design and surfaces
  • To discuss briefly the main challenges facing implant dentistry and what future developments might bring

The influence of systemic and local risk factors on the condition of the implant bed and implant outcomes

Tooth extraction without concomitant bone grafting results in osseous deformities of the alveolar ridge, such as reduced height and width. This makes subsequent management of aesthetics, prosthetics and implant placement very challenging. Socket grafting using regenerative bone materials has been shown to significantly reduce bone loss, maintain ridge dimensions and enhance the clinician’s ability to provide aesthetically and functionally satisfying restorations.

The aims and objectives of this lecture will be to discuss the biological risk factors that may influence the aesthetic, prosthetic and surgical success and delivery of implant treatment with special emphasis to site development and augmentation.

Learning Objectives

  • To discuss the effect of local and systemic factors including the patient’s immunological state, drug history (incl. plaque & biofilm) on treatment planning and success of implant treatment aesthetically, restoratively and surgically
  • To discuss the importance of site development and ridge preservation in influencing the aesthetic, surgical and restorative outcome of implant treatment
  • To discuss the steps of extraction socket grafting and ridge preservation
  • To present the instrumentation for successful surgical bone augmentation
  • To discuss the selection of appropriate bone graft materials and biological enhancements
  • To offer practical advice on socket augmentation and ridge preservation

Tea/Coffee & Exhibition
Role of imaging in treatment-planning discussions, prevention of complications and selection of ideal implant positioning

Diagnostic imaging is an essential part of the treatment planning process in implant dentistry. This presentation will explore the benefits, opportunities and risks that may stem from the radiological investigation.

Although 2D and medical CT imaging still have a useful role to play, the introduction of CBCT has irreversibly and dramatically changed the process of treatment planning, implant planning, implant surgery, and prosthetic reconstruction. Access to 3D imaging technologies enhances the operator's ‘3D-thinking’ and 3D perception and opens up a wealth of possibilities, including the use of angled or short implants to overcome anatomical limitations.

An informed understanding of the strengths and weaknesses of available imaging modalities, and the sensible use of available guidelines and optimisation strategies, will enhance the benefit to the patient, surgeon, and prosthodontist, whilst reducing the inherent risks of both the diagnostic and the implant procedure.

The ability to export CBCT data to planning software or for use in CAD CAM systems has revolutionised implant dentistry. Rapid technological advances in imaging have been accompanied by synergistic advances in computer aided design and in 3D printing and manufacturing technologies. All of this combines to improve diagnosis, facilitate and expedite treatment, and link the surgical plan to the planned prosthetic result, transforming the reconstructive process.

Learning Objectives

  • To review ADI guidelines on diagnostic imaging
  • To give a critical review of different diagnostic imaging techniques used in implant dentistry including their advantages and disadvantages and diagnostic capabilities
  • To briefly outline the risk of ionising radiation, the risk/benefit ratio and ALARA principle, and to explain how the concepts of optimisation and justification may be applied to implant dentistry
  • To briefly discuss 3D treatment planning and computer-assisted implant-placement techniques and how to utilise these techniques to improve treatment and minimise risks and complications

Keeping teeth, and not implants

Before implant dentistry was available, significantly more effort was placed on preserving compromised but well maintained teeth. Today, the increased confidence in osseointegration has influenced the decision to extract periodontally affected teeth, which in several cases may be treatable using conventional or regenerative periodontal therapies. The extraction of a periodontally compromised tooth and its replacement with a dental implant, as opposed to retention of this tooth, is today one of the most debatable decisions that a dentist has to take.

The treatment choice cannot be guided solely by the scientific evidence on the efficacy of these two treatment principles but should take under consideration personal clinical experience, access for technology and education as well as patient preferences, and economic parameters.

This presentation will discuss the relative success of keeping periodontally compromised but well maintained teeth versus placing implants in periodontally compromised patients. It will critically appraise the available literature on long-term survival and success rates, patient based outcomes and economic parameters of implant and teeth supported restorations in periodontal patients as well as the risk for complications in both cases. A combined patient and site risk profile assessment developed by our team will be presented which together with a cost–benefit analysis based on each individual patients expectations would be able to offer clinical advice on when to extract and replace with implants and when to retained compromised teeth.

Learning Objectives

  • To review the evidence on the prognosis and success of keeping periodontally compromised but well treated teeth
  • To review the evidence on prognosis/success of implant treatment in patients with history of periodontal disease
  • To offer practical and clinical advice on when to extract and replace with implants and when to retained compromised teeth

The pink hybrid restoration - the prosthetic solution for anterior ridge defects

Aesthetically replacing missing teeth in areas of significant anterior ridge deformities has been and still is a significant challenge in dentistry. High aesthetic expectations and the addition of implant therapy have only increased the challenge. It is, therefore, necessary for clinicians and technicians to fully understand all the available options and limitations as well as where, when, and how to best utilise them. This lecture will outline a new prosthetic option beside the existing, surgical and orthodontic options to enhance aesthetically the deficient anterior ridge. Emphasis will be placed on the analysis, design, benefits and manufacturing of the 3-dimensional prosthetic reconstruction of deficient ridges and its ability to enhance the aesthetic result of the final tooth form (White Aesthetics) and gingival design (Pink Aesthetics) as well as lip support.  A detailed decision-making protocol will be suggested to help guide clinicians and technicians toward creating the most successful aesthetic and functional outcome for their patients. 

Learning Objectives

  • To evaluate the limitations when restoring a deficient ridges - the decision-making process
  • To understand the importance of ideal soft tissue architecture for developing natural looking restorations - the white and pink interface
  • To look at when and how to utilise artificial gingiva
  • To look at clinical and laboratorial procedures when fabricating the pink hybrid restoration

"…but I haven't done anything wrong!” - Facing medico-legal challenges in implant dentistry

Over the past twelve years litigation against UK dentists has grown exponentially. Dentist are understandably angry and concerned when they are subject to a claim This session will look at what factors cause a claim to be settled and why claimant lawyers have been so successful in the dental market.  The session will go on to explore what steps a practitioner can take to reduce the chances of a successful claim. The key areas are making sure the correct diagnosis has been made, the treatment has been properly planned and valid consent obtained. The outcome of untoward or unexpected consequences of treatment will be discussed and the difference between an adverse outcome and “just one of those things” will be discussed. The importance of candour when untoward consequences happen will be explained and above all the importance of accurate contemporaneous records will be stressed.
