Proper 3D implant positioning is a crucial factor for predictable implant and prosthodontic treatment. Guided osteotomy preparation and placing implants through a guide may contribute to more precise implant placement in accordance with the prosthodontic plan. In the first part of the article (published in CAD/CAM 1/2019), we described the use of 3D imaging in implant treatment planning. This study aims at the comparison of two methods in terms of repeatability and compliance with the treatment plan.

The philosophy of prevention in all medical professions is increasing from a global perspective. In fact, prevention of chronic non-communicable diseases, the major burden of illness and disability in almost all countries in the world, has been strengthened in recent years. The motivation is to ensure a better quality of life for people and to reduce public health expenditures. In dentistry, periodontitis is one of the major chronic non-communicable diseases. World experts in periodontics and science have published several principles regarding the prevention of periodontal diseases.

Anti-ageing is a branch of medicine focused on how to prevent, slow or reverse the effects of ageing, thus helping people to live longer and healthier lives. Recently, however, more evidence-based medicine has led to antiageing becoming a multi-billion-dollar industry. In the past few decades, the market for anti-ageing products and services has grown into a global industry valued at an estimated US$261.9 billion in 2013, up from US$162 billion just five years before, according to BCC Research, a publisher of technology market research reports based in Wellesley in the US.

Planmeca is known for high-tech innovations and continuous product development. The company’s powerful Planmeca Romexis software platform allows all stages of the dental implant and aesthetic prosthodontic treatment to be completed using one piece of software, from the computer-assisted design of patients’ smiles to the fabrication of surgical guides. The following clinical case, which I performed together with my colleagues Dr Ponomarev, Dr Kozhevin and Dr Yarokhin, illustrates how digital solutions can be used in prosthodontic treatment, implant placement and restoration design. According to our experiences, digital CAD/CAM technologies enable maximal functional and aesthetic results compared to traditional methods.

The widespread use of intraoral optical impressions and constant improvements in dental computer-aided design (CAD) software today allow the practitioner to manage various kinds of clinical situations, from the simplest to the most complicated, by using different types of dedicated equipment (camera software, processors and, more recently, 3D printers) as part of a completely digital workflow. Arch scanning methods using intraoral scanners yield impressions that are comparable to those obtained with traditional equipment in terms of clinical precision because they eliminate the variations caused by the user, reduce the readjustment processing time and costs, and improve patient satisfaction and comfort.

The Straumann Pro Arch concept involves different treatment solutions for the fully edentulous patient. The objective is to provide a predictable, reproducible and simple treatment that restores patients’ oral health and consequently improves their quality of life dramatically. The possibility of immediate, same-day rehabilitation by means of temporary fixed prostheses offers maximum treatment quality and satisfaction for both the dental team and patient. The objective of the treatment with an immediately loaded fixed prosthesis on implants is to improve the patient’s quality of life by providing function, aesthetics and health until osseointegration is established.

March 28, 2019

The predictability of dental implant osseointegration has enabled clinicians and researchers to focus on additional success criteria in the overall treatment. Initial assessments of implant therapy considered survival rates, restoration stability, detectable bone loss and presence of soft-tissue infection. As implant dentistry advanced, it was necessary to introduce new assessment points in order to broaden the understanding of favourable outcomes and pending failures. These included aesthetics, evaluated by both patients subjectively and clinicians objectively. A more patient-centred approach has led to a better insight into patient satisfaction, which was often overlooked in the past.

When working with dental implants, a number of specific rules must be followed regarding both the implant surgery and the prosthesis itself (fixed protheses tending to have a more favourable prognosis than overdentures). If these rules are not adhered to, the results are often unsatisfactory, requiring retreatment. In such cases, and despite the patient’s desire to quickly forget the previous treatment, a very strict protocol must be followed, specifically concerning the length of healing periods. Despite an increase in the overall treatment duration, this will ensure success of each stage of treatment. The implant retreatment case outlined in this article will emphasise these different stages in this type of clinical situation.

Dental autotransplantation entails extracting and repositioning a tooth into a different site in the mouth of the same patient. A successfully transplanted tooth offers several advantages, given the preservation of the periodontal ligament: the proprioceptive function is maintained, the alveolar bone volume is preserved, orthodontics can be included in the treatment plan, and the dentofacial development and growth of the jaws are not impaired. Moreover, pulp regeneration and continued root development can be expected when a donor tooth with incomplete root formation is chosen and infection of the pulp tissue is prevented. [1, 2]

What do endodontic experts base their decisions on: intuition, experience or CBCT imaging? The following case report on a 10-year-old patient shows that an apical lesion does not necessarily mean the affected tooth has to go. Using flexible nickel-titanium (NiTi) files, even root canals with curves or special features can be cleaned safely and with long term success.

The maxillary sinus is the largest paranasal sinus and overlies the maxillary alveolar process. The topographic anatomical relationship between the maxillary posterior teeth and the maxillary sinus necessitates great care in performing endodontic treatment. It has been suggested that the incidence of sinusitis of dental aetiology is increasing. One reason for this apparent increase may be the availability of improved imaging, specifically in-office cone beam computed tomography (CBCT) scanning.

Minimally invasive—the most well-known oxymoron in dentistry—is probably nowadays considered the new standard of care in almost every field of dental medicine, but more so in endodontics. Despite improved oral and dental health, the demand for endodontic treatment and restorations remains high among individuals with relatively complete dentition and dental awareness. The need for adequate endodontic treatment is most likely one of the driving forces behind all the improvements that have reached practitioners in recent years. The use of nickel-titanium (NiTi) rotary files in root canal preparation is one of those improvements and has provided a reduction in the frequency of procedural errors and the time required for chemomechanical preparation in relation to manual files.

Patients facing the loss of their natural dentition have more treatment options than ever before. The traditional complete denture, once the standard of care for the fully edentulous patient, is slowly but surely giving way to fixed full-arch implant restorations as their superior stability, function and aesthetics become more well known. Further, prosthetic materials have advanced in leaps and bounds, and monolithic zirconia can now be milled for fixed full-arch indications. By moving beyond acrylic and its vulnerability to wear, chipping, stains and fracture, this adds long-term durability to the qualities that make the fixed implant prosthesis the ultimate restorative option for fully edentulous cases.

The aesthetics are always a significant challenge during implant restoration, especially in the aesthetic zone, in addition to the full consideration required regarding function. In this article, we present a case of multiple tooth fractures due to trauma. After tooth extraction, immediate implantation and guided bone regeneration (GBR) were performed. During the prosthetic procedure, the design and transfer of the emergence profile of the soft tissue, functional design and occlusal adjustment, as well as the CAD/CAM process, were satisfactorily realised to achieve the aesthetic and functional goals.

CEREC and oral surgery? In times when patients go to a practice to receive complete, aesthetic, state-of-the-art treatment as quickly as possible, I think they go together very well. I did not always think so. Certainly, CEREC was always interesting; I have used it since 2003, but I did not always find the results convincing. In 2014, I had a closer look at an event in Salzburg, Austria, and learnt two things: the system had been further developed, and in particular, the precision had been improved considerably. It fits well in my practice; I use it almost every day because I have many patients who have busy jobs and do not have much time. I experience a great workflow in the practice that gives me maximum flexibility. Depending on the indication and the patient’s wishes, I can decide whether to make the restoration myself or outsource it to a laboratory, which I often do for more elaborate bridges. Then, I send the scan directly to my partner laboratory via Sirona Connect—that is very reliable.

Placing an implant immediately after tooth extraction offers several advantages, including a reduced treatment time, fewer surgical sessions, possibility of fixed implant temporisation, and preservation of the soft-tissue contour and of the interdental papillae. Immediate implant placement into fresh extraction sites has been described as a predictable and successful procedure when proper protocols and case selection are followed. The success of immediate implant placement and the temporisation procedure relies greatly on sufficient primary stability of the implant. The latter depends on the volume of available bone beyond the root apex as classified by Kan et al. ^[1] and on the choice of the implant, its macro design and the drilling protocol. BLX implants (Straumann) were designed to achieve high primary stability when placed immediately after extraction.

The digital revolution has changed the world and dental medicine is no exception. We live in the digital era: we have the materials and techniques that allow us to develop a totally digital workflow, allowing dental medicine to grow to a new level, becoming faster and more efficient, when combined with scientific and clinical knowledge. There are numerous technologies that simplify the daily work, such as intraoral, extraoral and face scanners, CBCT (cone beam computed tomography) with a low radiation dose, and software processing and production, better known as CAD/CAM (computer-aided design and manufacturing), which together with new aesthetic materials and prototyping tools (milling machines and 3-D printers) are radically transforming dental medicine. This case report has the aim of presenting an example of prosthetic digital workflow, with the integration of several technologies that help us achieve treatment success.

Different materials and treatment options are available in aesthetic and restorative dentistry for the anterior region. The conventional protocol, including an analogue impression with polyether or polyvinylsiloxane, a master cast and die fabrication, waxing and pressing of ceramic materials, requires exceptional skills and is technique-sensitive. Intraoral scanning and digital impression taking provide an accurate alternative method for transferring information from the mouth to the dental laboratory. The digital file is always on the computer and can be immediately processed or at any time, unlike with the conventional procedure.

The communication between dentist and patient is important, especially in cases of partial or complete aesthetic restoration in the anterior (smile makeover). Nowadays, it is important not only to treat oral pathology, but also to request an aesthetic evaluation of the patient’s smile to obtain results that respect the patient’s aesthetic expectation. The smile is our business card and represents the first thing that distinguishes us in human relationships, in work and in social life. It is necessary to know that a smile can appear unpleasant even if there are no evident issues or pathology, influencing people/patients’ psychologically. The clinician should understand the psychological needs of desire, perception and personality to explain in a better way the necessary therapeutics and/or aesthetic choices. When a smile is being designed, these parameters are fundamental and dependent on the communication with the patient and they should be considered in the evaluation of a 360° clinical approach. It often happens that patients are not able to identify their expectations, so dentists must be able to consider whether their exigencies can be satisfied.

Biofilm is the most significant cause of inflammatory bone loss around teeth and implants. Diagnostics, biofilm management and, where necessary, treatment help in patients with this problem. The W&H No Implantology without Periodontology workflow should provide stable tissue prior to implantation through prevention, and implant success in the long term through aftercare—something that is advantageous to both the patient and the treatment team.

With greater public awareness about cosmetic dental reconstructions, the dentist is often challenged with greater demands from the patient. This increased demand for aesthetic restorative treatment challenges the dentist, laboratory technician and dental manufacturers to develop techniques and materials to satisfy the discerning patient. Utilising digital planning, modern materials and effective techniques, the restorative team can succeed in restoring a smile to proper form, function and health. The case presented in this article demonstrates the significance of a systematic approach to planning, preparation and material selection in full-mouth reconstruction of a patient’s dentition.

The aim of the current investigation was to review techniques and materials available to achieve bleeding control during periapical surgery. An adequate bleeding control is crucial, since it improves vision in the surgical site, minimizes surgical time, enhances the root-end resection and filling, and reduces surgical blood loss, postsurgical hemorrhage and postsurgical swelling.
