The goal of the workshop is to demonstrate an alternative treatment method for volume control and stability of the biomaterial for horizontal and vertical augmentations with simultaneous implant placement. The titanium iGen membrane system can be used with almost any implant system available on the market. By selecting the proper type of membrane one can cover simple horizontal defects but also treat advanced and extended clinical situations. The workshop will give you valuable practical hints and tips to successfully employ this alternative treatment method.
The concept of aesthetics can be understood and interpreted in different ways and depends on the individual situation of the patient. Planning prosthetic treatment allows us to determine optimum positions for implants and the shape of the teeth but at the same time allows predicting the limitations associated with pink aesthetics. On the basis of proper planning, communication with the patient is essential. It enables us to make prosthetic restorations that meet the patient’s expectations, taking into account the limitations of a particular case. This is true for both single tooth reconstruction and complex cases. During the lecture Dr. Chmielewski will present the planning techniques and treatment with prosthetic restorations to achieve optimal soft tissue aesthetics.

The use of soft-tissue grafts buccally of immediate implants leads to a thicker peri-implant mucosa that is located more coronally and to a better aesthetic outcome. Subepithelial connective tissue grafts have been used for many years in plastic periodontal surgery in the aesthetic zone, but the additional surgical site at the palate (donor site) leads to a higher postoperative morbidity for the patient. For this reason, biomaterials such as acellular dermal matrices have been introduced to replace autogenous soft tissue grafts. Acellular dermal matrices show good biocompatibility. In addition, they have shown the potential to thicken oral mucosa buccally from teeth in an animal study and also at implants in various clinical studies. The lecture will show results of a clinical study comparing an acellular dermal matrix versus connective tissue grafts in conjunction with immediate implants in the aesthetic zone.

Gingival recession with the exposure of root surfaces is a common occurrence and requires treatment due to aesthetic concerns or root sensitivity. Several surgical techniques have been developed to treat gingival recessions, including those employing connective tissue grafts, various flap designs, guided tissue regeneration. Autogenous soft-tissue transplants are considered the gold-standard for covering gingival recessions, but are limited of tissue that can be harvested from the patient’s palate. Moreover, harvesting autogenous transplants is often associated with pain and discomfort for the patient. More recently, the use of xenogenic 3D native collagen matrices has been introduced to soft tissue grafting. The various techniques in the treatment of single and multiple gingival recessions, as well as current trends are discussed in this presentation.

The classical shell technique developed by Prof. Khoury has widely been accepted as a reliable bone augmentation technique. However, many clinicians and patients refrain from harvesting autogenous bone blocks from intraoral or extraoral harvesting sites for moderate sized defects.
The use of allogenic cortical plates enables structural bone reconstruction yielding clinically similar results, especially in terms of implant success. In the workshop Peer Kämmerer will address important factors that need to be taken into consideration when handling cortical plates. During the hands-on, different clinical situations will be addressed, with the focus on plate positioning and immobilization.
Autologous grafts are still considered the gold standard for the regeneration of bone defects. However, their availability is limited and sometimes quantities are not sufficient for the specific clinical needs. Furthermore, the possible donor site morbidity and pain for the patient associated with a second surgical site often call for other treatment options. Allogenic, xenogenic or synthetic biomaterials can therefore be a valid alternative to the patient’s own bone.
In this lecture Peer Kämmerer will show how allogenic grafting materials can be used as an alternative to the patient’s own bone. He will show various clinical cases in order to illustrate the properties and advantages of these materials. In addition to the “classical” GBR-methods, Dr. Kämmerer will focus on the allogenic shell technique which can be used to treat complex bone defects with minimal morbidity.

Complex alveolar ridge defects are demanding and special treatment strategies are necessary. Depending on the shape and size of the defect, the clinician needs to choose the ideal solution. In clinical practice, the application of allogeneic blocks has been established as a reliable alternative to autogenous bone blocks for alveolar ridge augmentation, to avoid donor site morbidity and limitations in material quantity. In the hands-on part the participants will practice surgical procedures for block augmentation like flap design and block shaping and will learn more about soft tissue management.
Learning outcomes and key topics of the workshop:
- Indication-based choice of biomaterials
- Evaluation of the advantages and disadvantages of allogeneic bone grafts
- Illustration of the surgical procedure and use of allogeneic bone blocks by means of clinical cases
- Hands-on training on block augmentation including shaping, fixation and suturing techniques
Despite the development of short and diameter-reduced implants, many patients still require alveolar ridge augmentation procedures to facilitate optimal implant stability and hence, clinical success. Depending on the defect size and geometry simultaneous or delayed techniques are available. Especially in extreme atrophies and complex situations block augmentations are the preferred technique.
Besides autogenous bone grafts allogeneic bone blocks nowadays attract the attention of oral surgeons. Free availability and the avoidance of donor site morbidity are the main advantages of allogeneic blocks. Subject to the right indication similar outcomes of allogeneic bone compared to autogenous bone are described in the literature. With the introduction of CAD/CAM technology and custom-milled bone grafts another advantage opened up: better accuracy of fit, resulting in a maximum of contact area between graft and local bone. Dr. Dr. Frank Kloss will present clinical data and cases from his five years of experience using allogeneic blocks.

The Bone Ring Technique is an innovative solution for single-stage three-dimensional bone augmentation and implant placement. The simultaneous augmentation and implantation reduces treatment time compared to conventional bone block augmentations. The technique was initially established with autogenous rings harvested from different donor regions. The development of prefabricated allogenic rings has greatly facilitated the procedure, leading to reduced morbidity and faster incorporation into vital bone.

Healthy and long-term stable dental implant treatment requires both adequate hard and soft tissue conditions. However, loss of keratinized tissue after tooth loss as well as extensive flap management for coverage after grafting procedures may lead to compromised gingiva quality and quantity around implants. It is well known that adequate width of keratinized or at least fixed mucosa around implants facilitates oral hygiene which in turn protects from peri-implant diseases. Therefore, different techniques such as vestibuloplasty with or without free gingival grafts or xenogeneic materials have been developed to improve the peri-implant soft tissue quality and quantity. The workshop will start with a theoretical introduction into the topic. Following, in the practical part, participants can practice the presented techniques in a hands-on training on pig jaws.

Clinically, it is a big challenge to create natural gingival aesthetics following immediate or delayed implant placement. Stability of the soft tissue during implant surgery is of major importance for the implant site and adjacent teeth. A flapless surgery can be performed in cases where only the tooth is compromised and not the soft tissue or osseous form. In cases of a localized horizontal/vertical deficiency, dehiscence, or fenestration another approach is necessary.
From a prosthetic prospect, the soft tissue architecture around implants must be similar or close to that of the natural tooth. The dental lab can deliver the best functional and aesthetic work, it will be harmonious only if the soft tissue dimensions are maintained or developed surgically or with the help of the prosthetic reconstruction. Single implant placement has proven to be more predictable than multiple implant placements. In multiple implants and late loading it is possible to develop a soft tissue outcome with provisionals or proceeding directly to the final reconstruction. This is done with the help of a wax-up on the final metal frame controlling the pressure of the soft tissue intraorally.
The lecture will show the difference between surgical and prosthetic soft tissue outcomes. The role of a wax up before surgery and during the prosthetic phase of implant treatment will be discussed.

The workshop will be focused on the surgical regenerative approach to the intrabony defect. Single and double flap designs will be thoroughly described in combination with specific regenerative devices aimed at optimizing the treatment outcomes while minimizing post-surgery
Changes in horizontal and vertical dimensions of post extraction sockets require surgical strategies to counterbone remodeling in order to facilitate implant positioning at a later stage. During the presentation an evidence-based decision-making process aimed at combining the surgical approach with proper regenerative devices in different clinical conditions will be illustrated.

The workshop provides a unique opportunity for participants to receive first-hand clinical experiences and instructions for the application of botiss permamem® and botiss Jason® membrane. During the course, the clinical steps of a novel flap design and a predictable reconstruction approach of localized 3D alveolar defects will be presented on pig jaws.
The lecture focuses on two newly developed synthetic barrier membranes designed for Guided Bone Regeneration. Prof. Windisch will present first hand experiences as well as the handling properties and benefits of a new high-density PTFE and a magnesium barrier membrane used for regeneration of advanced alveolar defects.
Several reconstructive surgical methods are suggested in the literature to rebuild the deficient alveolar ridge, such as transplantation of autogenous bone blocks, distraction osteogenesis as well as guided bone regeneration (GBR). Among these, GBR is documented to have the widest field of indication in terms of defect morphology. The essence of GBR is to maintain a secluded space under a barrier membrane preventing epithelial soft tissue migration to stabilize blood clot formation with any particulate auto- or xenografts. Recently, a new generation of non-resorbable polytetrafluoroethylene (high-density PTFE) has been introduced. This membrane is characterized by improved tissue compatibility and resistance against postoperative infections in case of membrane exposure compared to ePTFE and nPTFE. Furthermore, the first data for a novel resorbable synthetic magnesium membrane will be shown. Magnesium is a highly biocompatible metal that exhibits excellent mechanical properties together with a positive effect on osteoblast activity and antibacterial effects.
In this lecture, the first results in GBR procedures for both membranes will be addressed, highlighting the benefits and handling properties of the novel materials.

The Bone Ring Technique can be performed using prefabricated bone rings of processed allogenic donor bone. The ‘allograft Bone Ring Technique’ allows bone augmentation and implantation in a one-stage procedure like the classical bone ring technique but eliminates the need for bone harvesting. As a result, allogenic bone rings reduce pain, risk of infection, morbidity, and surgical time significantly. After five years of clinical experience the Bone Ring Technique with allografts shows good results for both, vertical and horizontal augmentation and excellent new bone formation. Results of biopsies taken after six months as well as clinical outcomes will be discussed in the presentation. The workshop will show a step-by-step protocol and tips for the surgical procedure in different clinical indications. Important factors for treatment outcomes such as suture techniques, flap mobilization and tension-free wound closure will be demonstrated. The simplification of the surgical treatment of three-dimensional bone defects is now possible with this recommended technique. The lecture focuses on recent clinical and animal studies with autologous and allogenic bone rings and long-term clinical outcomes.
3-dimensional bone defects can be treated in a one-step protocol using the Bone Ring Technique. If the recommended treatment protocol is followed and risky anatomical regions are respected, bone grafting and implant placement using the Bone Ring Technique can be performed safely. Possible donor sites for the Bone Ring Technique include, in addition to the chin, the palatal bone and the retromolar region. Crucial elements of successful soft tissue management following extensive bone augmentation are a correct flap design and a tension-free closure of the flap. Participants will have the chance to see the long-term clinical outcomes of prefabricated allogenic and autogenous bone rings.

The treatment of gingival recessions has become an important therapeutic issue due to the increasing number of cosmetic requests from patients.
The goal of mucogingival procedures is to obtain complete root coverage, up to the cementoenamel junction, along with an increase of soft tissue thickness to maintain the result in the long term, reducing the risk of recession recurrence. The use of a coronally advanced flap in conjunction with a collagen matrix avoids the need for autograft harvesting, thus reducing patient morbidity and discomfort. The collagen matrix will support blood clot stabilization by serving as a scaffold for ingrowing blood vessels and fibroblasts; within a few months, the matrix will be completely degraded and the blood clot will be gradually transformed into new connective tissue, which will be responsible for the increase in soft tissue thickness. This represents a key aspect of the long-term success of root coverage.
The use of a promising porcine acellular dermal matrix for recession coverage as well as its long-term clinical outcome will also be described.
