Prof. Dr. Urs Braegger



Management and prevention of hard tissue related complications with implant supported reconstructions

In the introduction, the impressive amount of service needs for patients who have been restored with implant supported reconstructions will shortly be summarized according to published evidence.
Technical complications and failures may occur at each component and at each interface between implants, prosthetic components and the reconstruction provided by the dental laboratory. Starting with the implant body and ending with the suprastructures, the lecture will lay out all possible locations where events may occur, the handling of the problem and how to prevent the specific complication. The lecture will comprise numerous clinical cases and how the problems were solved – thus, providing many tips for patients and the practice team.


How to remove a fractured component with the service set

During the workshop of Prof. Braegger, participants will be familiarized with a dedicated service set especially developed for the retrieval of broken or non-retrievable prosthetic components. Participants will learn the different indications and how to safely apply the tools. The entire process will require complete concentration and knowledge of the correct use of the precision instruments according to the manufacturers step by step instructions. The hands-on exercise includes the management of a blocked mucosa former as well as the removal of a fractured abutment screw. Furthermore, participants will be instructed on how to check that the entire fragment has been successfully removed. In addition, the administrative handling of complaints and practical hints for the organization of the patients’ visit will be provided.

Dr. Devorah Schwartz-Arad



Recovering the maxilla and the lip support – Advantages of combined therapy

Alveolar bone deficiency, especially in the anterior maxillary area, can prevent ideal implant placement and jeopardize the esthetic outcome. The anatomic configuration in the atrophic site, creates acquired Angle Class III malocclusion influencing the surgical choices. Clinical cases of severe maxillary atrophy are described as a combination of sub-nasal, sinus elevation procedure and intra-oral autogenous bone used for ridge augmentation prior or simultaneously with dental implant placement combined with xenograft material mixed with platelets-rich-plasma (PRP) or bone-marrow aspirate (BMA) and covered with platelet-poor-plasma (PPP) as a biological membrane. Le Fort I Osteotomy were performed in few cases, simultaneously with dental implantation and immediate loading or as a second procedure.
The combination of few augmentations and surgical procedures enables better correction of the alveolar ridge in 3D (height, width and trajectory), which results in
better prosthetic and esthetics outcomes. Techniques that are described in this presentation should be considered reliable, safe, and very effective to obtain high bone graft survival rate following high long-term implants’ survival rate. Moreover, we believe that PRP and BMA as an autologous source of growth factors and stem cells mixed with osteoconductive bone substitute and covered with PPP as a biological membrane may offer a novel therapy with greater efficacy than any other combination or single therapies that were used in bone regeneration up to now.

Prof. Dr. Ziv Mazor



Managing ridge atrophy using the osseodensification concept

Dental implants have become an optimal solution for replacing missing teeth. Long-term studies validate this treatment option in single as well as complete edentulous patients.
Bone resorption sometimes makes implant placement a difficult task both in anterior as well as posterior regions demanding advanced surgical regenerative procedures. In some situations, it requires long term treatment with an unpredictable prognosis.
The presentation will focus on the concept of using new innovative treatment approaches as well as unconventional surgical manipulations dealing with the atrophic ridge.
The new concept of “osseodensification” will be presented enabling the clinician to preserve existing bone and enhance the outcome through a minimal invasive approach. Osseodensification is a novel, bio-mechanical, non-excavation osteotomy preparation method. Unlike traditional bone drilling technologies, osseodensification does not excavate bone tissue. Rather, it preserves bone bulk, so bone tissue is simultaneously compacted and autografted in an outwardly expanding direction to form the osteotomy. It is accomplished by using proprietary densifying burs. When the densifying bur is rotated at high speed in a reversed, non-cutting direction with steady external irrigation (Densifying Mode), a dense compacted layer of bone tissue is formed along the walls and base of the osteotomy.
The presentation will show step by step the procedure of this minimal invasive, innovative technique for ridge expansion as well as sub crestal sinus augmentation with long-term follow ups of both clinical and CBCT radiographs. It will highlight the benefits of this treatment modality compared to the existing techniques.

Prof. Dr. Sofia Aroca



State-of-the-art of soft tissue regeneration around teeth

In the daily practice, the clinician often faces soft tissue defects around teeth. In order to treat them, the practitioner has at his/her disposal several surgical treatment modalities, which can make the right choice to achieve the best result difficult. Based on the available scientific literature and clinical experience, different surgical protocols will be discussed to manage the soft tissue defects around teeth.
The techniques to surgically treat recession type defects are mainly derived from the coronally advanced flap, the supraperiosteal envelope technique in combination with a subepithelial connective tissue graft, or its evolution as a tunnel technique. They have been developed to achieve a complete root coverage with improved aesthetic outcome, but few of them can provide complete root coverage in RT2/RT3 recessions as these types of defects present loss of interproximal
bone and soft tissues. Dr. Aroca will describe in detail the modified tunnel technique and focus on all parameters that must be evaluated to make the decision making process less complex and the results more predictable. We also will immerse into the biology of the tissues in order to have a better understanding of their management and to learn how to create a favorable environment for a predictable healing.
Therefore, the goal of this presentation is to share different surgical protocols to manage soft tissue defects successfully and to provide a deep knowledge to apply them in the daily clinical practice.


Periodontal plastic surgery, treatment of multiple recessions

Periodontal plastic surgical procedures aiming to treat multiple recession defects have been extensively described in the literature. Most of them can be combined with CTG or with soft tissue substitutes in order to increase the marginal gingival thickness, which in turn ensures long-term stability.
– The surgical procedures used to treat recession defects are technically very sensitive and need a deep knowledge on behalf of the clinician in order to obtain predictable results.
– The course will focus on the step by step presentation of the tunnel technique as well as a comprehensive philosophy of surgical risk factors need to be taken into account to optimize the
clinical outcomes. Clinical cases and surgical techniques using connective tissue grafts and a new resorbable matrix will be demonstrated.

Current concepts in reconstructive periodontal surgery

The management of teeth periodontally compromised by deep intraosseous lesions has been a major therapeutic challenge for many years. For this purpose, various surgical techniques and biomaterials have been investigated in an attempt to reconstruct lost or damaged periodontal tissues. Thus, reconstruction of periodontal tissues may be achieved by application of barrier membranes, grafts, biological agents, and their combinations. However, although reconstructive procedures are widely accepted as safe and effective, there is a high variability in treatment outcomes. Recently, minimally invasive surgical and non-surgical treatment options have been introduced with the aim to minimize tissue trauma, decrease patient morbidity and simplify the treatment procedure.
The goal of this presentation is to update clinicians on the recent advances in biomaterials and surgical techniques in reconstructive periodontal procedures.

Grafting procedures in implant dentistry: Autografts, alternatives and creative innovations

One of the most challenging procedures in implantology is the predictable and safe regeneration of lateral and vertical bone defects. Besides autogenous bone as the gold standard for jaw augmentation procedures, different biomaterials, such as bone substitutes and membranes have shown predictable results especially in lateral grafting applications. In contrast to the patient´s own bone, their use is not accompanied by donor site morbidity, leading to high patient acceptance. Moreover, careful selection from different bone substitutes can focus on specific properties like volume stability, osteogenicity, origin, porosity, and ease of clinical application. However, the use of bone substitutes is accompanied by the risk of soft tissue ingrowth and subsequent incomplete graft regeneration. The use of a pericardium-based collagen membrane allows for long barrier function but still maintaining advantages of the native collagen structure, such as biocompatibility, tissue integration, nutrition transfer and graft stabilization. However, quality of the recipient site, the osteogenicity of the graft, a transmembraneous angiogenesis of the barrier and the selected healing time are also affecting the predictability of the regeneration outcome.
Newly developed techniques, such as splint and ravioli technique as well as bonebuilder are focusing on graft immobilization and ease of clinical application. They might be interesting additional tools to fulfill the increasing expectations of the modern patient.
