Soft-tissue Augmentation and Corrections for the Prevention and Management of Peri-Implant Diseases

Abstract: Soft-tissue augmentation has become an essential measure for both the prevention and management of peri-implant diseases. This mainly refers to the establishment of an adequate width of keratinized tissue to provide a mechanical protection against plaque biofilms, but also soft tissue volume augmentation to compensate the occurrence of mucosal recessions following surgical treatment of peri-implantitis.

Speakers: Dr. Daniel Thoma & Dr. Todd Scheyer
An Innovative Volume-Stable Collagen Matrix for Soft-Tissue Augmentations at Pontic and Implant Sites

Abstract: Today, implant and reconstructive therapies include a variety of clinical steps to optimize biological and esthetical outcomes. Soft tissue grafting procedures are considered an integral part of implant therapy and various techniques and materials are applied at different time-points. Whereas autogenous transplants are still widely used, they are associated with major disadvantages, most prominently the associated morbidity. Therefore, more recently, a number of soft tissue substitutes have been developed and some of them demonstrate favorable clinical success and less morbidity. This workshop will focus on the clinical decision tree and include step-by-step procedures for the above-mentioned clinical interventions based on recent clinical and scientific evidence.
Theoretical part (very short, mainly illustrating the techniques with clinical cases):

  • What are today’s options to autogenous soft tissue grafting?
  • Soft tissue management to increase volume: time-points and grafting techniques 

Hands-on part:

  • Classic palatal island flap on pig jaw maxilla (one side) -> insertion of Fibro-Gide with open flap, buccally
  • Soft tissue punch -> removal of soft tissue to simulate an extraction socket -> split thickness flap -> insertion of Fibro-Gide into pouch, buccally -> to simulate soft tissue thickening in immediate implant sites on pig jaw maxilla (other side)
  • Soft tissue thickening under pontics (pig jaw mandible) -> insertion of Fibro-Gide with open flap, covering crest as well 

Speaker: Dr. Christer Dahlin
Ridge Augmentation by GBR (flap designs, material aspects, suturing techniques)

Abstract: The aim of this workshop is to discuss and practice on the fundamental principles for guided bone regeneration. The course will include a short biological introduction followed by hands-on practice how to the use of biodegradable membranes and bone substitute materials for lateral ridge augmentation. Furthermore, the use of a novel non-resorbable membrane for vertical ridge augmentation will be presented. The course will emphasize on membrane fixation, flap design, how to create a tension-free flap as well as suturing techniques and choice of suture materials. During the course surgical videos will presented as well as case presentations. The importance of proper post-operative care and follow-up will also be discussed.

Speaker: Dr. Mauricio Araújo
Ridge Preservation: Rationale, Indications and Techniques

Abstract: Post-extraction bone loss represents a challenge for the clinician. It may lead to esthetic problems and more complex implant installation due to dimensional alterations of the ridge. Ridge preservation is a clinical procedure that aims at preventing such bone loss following tooth extraction. The current workshop will describe and discuss the technique for a minimally invasive tooth extraction. Subsequently, the technique for ridge preservation including the graft of the socket and the use of gingival graft for closing the entrance of the socket will be also described and discussed.

General Sessions

Future Prospects for Periodontal and Peri-Implant Regenerative Medicine

Abstract: The reconstruction of alveolar bone defects caused by development abnormalities, trauma or disease is a major goal of oral reconstructive therapy. The field of tissue engineering combines advances in materials science and biology to repair tissues and organs. Over the past decade investigators have utilized growth factor biologics, barriers and bone replacement grafts to restore lost tooth support due to damage of the alveolus. This presentation will highlight emerging technologies in 3D printing, bioprinting, biomaterials, and growth factor biologics for application to the clinical arena.

Speaker: Dr. Michael McGuire
Evidence-Based Alternatives for Autogenous Grafts: Outcomes, Attachment and Stability

Abstract: The ability to predictably treat gingival defects with grafts has been one of the cornerstones of periodontal therapy over the past quarter century. During this time, surgical techniques have been refined and modified to become less invasive and more esthetic. This program will review and contrast alternatives for autogenous grafts as they relate to clinical outcomes, patient based outcomes, root surface attachment and long-term stability.
Educational Objectives:

  • State the objectives and goals for gingival augmentation
  • Compare the various techniques and how they differ with respect to the goals of soft tissue augmentation

Speaker: Dr. Craig Misch
New Techniques in Hard Tissue Regeneration to Support Implant Therapy

Abstract: There are several techniques and materials available for implant site development. The choice may depend on a number of factors including size of the defect, osseous morphology, costs and surgeon or patient preferences. Autogenous bone has long been considered the gold standard of graft materials. The trend today is to reduce patient morbidity but still provide predictable outcomes. This lecture will discuss the use of various methods for hard tissue augmentation.

Speaker: Dr. Marc Nevins
Maximizing Biological Potential for Periodontal and Alveolar Bone Regeneration

Abstract: This presentation will provide an update on therapeutic options for periodontal regeneration and ridge preservation. The ability to provide predictable treatment options for our patients continues to evolve. Today there are options utilizing growth factors (e.g. rhPDGF-BB) combined with natural scaffolds (FDBA or anorganic bovine bone matrix (ABBM) . In addition, for periodontal therapy the use of lasers has significantly evolved with proof of principle evidence for periodontal regeneration.
Topics covered:

  • Periodontal regeneration with biomaterials grafting and growth factors
  • Options for minimally invasive periodontal regeneration including laser periodontal surgery (LANAP)
  • Management of esthetic sites with minimally invasive esthetic ridge preservation

Speaker: Dr. Paul Rosen
Regenerative Treatment for Peri-implantitis: When Is It Advisable? What Makes It Predictable?

Abstract: Dental implants are not immune to biologic complications and peri-implantitis is a disease entity that threatens their survival due to bone loss beyond physiologic modeling/remodeling. The dilemma for clinicians is that the systematic reviews provide no clear idea of how to best manage this problem. Several recent articles have been published that employ a regenerative algorithm which has demonstrated predictable short- and long-term success for treating peri-implantitis. This lecture will explore the rationale to this regenerative protocol and will highlight its essential aspects for achieving long-term success.

  • Discuss the advantages to a regenerative surgical approach for treating peri-implantitis.
  • Discuss the difficulties behind implant surface decontamination.
  • Identify when a regenerative surgical approach may be predictably implemented to restore maintainable health to the failing dental implant.

Speaker: Dr. Hom-Lay Wang

Abstract: Implant complications have become a daily challenge for many practicing dentists. This presentation is designed to provide current approaches in managing implant biological complication, these include but are not limited to: chemotherapeutic agents, apically positioned flap with or without implantoplasty, implant surface detoxification (e.g., lasers), guided bone regeneration, soft tissue grafts, implant removal as well as re-implantation. Decision tree of how to select and manage the implant bone loss and peri-implantitis will be presented.
Learning Objectives

  • Recognize factors that contribute to implant complications
  • Know how to use decision tree to select proper treatment modality to manage implant complications
  • Familiarize yourself of most common ways of managing implant biological complications today

Speaker: Dr. Frank Schwarz
Surgical Regenerative Therapy of Peri-Implantitis

Abstract: Previous studies have indicated that surgical treatment of peri-implantitis with concomitant placement of a bone filler is associated with clinical and radiographic improvements on both short- and long-term periods. However, the available evidence also suggests, that the effectiveness of regenerative treatment approaches is influenced by several factors, such as the type and configuration of the defect, implant surface characteristics, as well as the method of surface decontamination.

  • Surgical techniques and materials for regenerative therapy of peri-implantitis associated defects
  • Decontamination protocols
  • Combination procedures for advanced defects (respective/regenerative)
  • Soft tissue volume grafting for the prevention of postoperative mucosal recessions
  • Indication based flap- and suturing techniques

Vertical Ridge Augmentation - Current and Future Trends

Abstract: The principle of guided bone regeneration has historically implied that the membrane acts as passive barrier, hence protecting the bone defect and allowing bone formation to occur without intervening from the soft tissue. Recent findings implies that barrier membranes plays a much more active role in the healing process and are fundamental for regulation of cell activities within the defect not only in the vincinity of the barrier but also in more peripheral parts of the defects. This presentation will address the most recent findings within this field and also discuss how this findings will affect the clinical use of both biodegradable as well as non-resorbable membranes in more advanced situations and also the design of the next generation of barrier membranes.
Learning Objectives

  • Biodgegradable and non-resorbable membranes regulate cell activity within bony defects.
  • In the combination with bone substitute materials, the healing process are also regulated by the membranes.

Speaker: Dr. Mauricio Araújo
Management of the alveolar socket following tooth extraction

Abstract: Post-extraction bone resorption represents a challenge for the clinician. It may lead to esthetic problems and more complex implant installation due to dimensional alterations of the ridge. Thus, the concept of preventing bone loss following tooth extraction is very attractive. The current presentation will describe a series of studies regarding the preservation of the alveolar process dimensions following tooth extraction. It will be demonstrated that socket graft with bone substitutes can compensate for post-extraction bone loss. Clinical cases that illustrate the surgical technique and outcome of ridge preservation procedures will be presented and discussed.

Speaker: Dr. Gustavo Avila-Ortiz
Management of the Posterior Maxilla - Sinus Augmentation

Abstract: Maxillary sinus augmentation (MSA) is generally recognized as a predictable technique for implant site development in the posterior maxilla. In spite of the widely spread notion that practically any biomaterial will lead to successful regenerative outcomes, current understanding of the healing processes following MSA indicates that the selection of the grafting material, as well as the surgical approach and several patient-related factors, may play a major role in the healing dynamics depending on the clinical scenario. This presentation will focus on reviewing relevant evidence regarding techniques, biomaterials and local and systemic factors that may influence MSA outcomes, with the objective of addressing some myths and realities.

Speaker: Dr. Daniel Thoma
Shifting Paradigm for Soft-Tissue Augmentation in the Esthetic Zone

Abstract: Treatment strategies using implants in the esthetic zone are complex and long-term stability of functional and esthetic outcomes rely on healthy biological conditions. Clinical data suggest that hard tissue regeneration is responsible for roughly 60% and soft tissue augmentation for roughly 40% of the final volume at implant sites. This underlines the importance of adding a soft tissue grafting procedure to provide healthy peri-implant tissues and favorable esthetics. Therefore, the number of soft tissue grafting procedures is increasing. Autogenous soft tissue transplants are considered to be the gold standard. However, recently developed collagen-based soft tissue substitutes provide similar outcomes with respect to soft tissue volume, but are associated with less morbidity and complications than autogenous grafts, thereby offering significant benefits for patients and clinicians.

Soft-Tissue Augmentation to Enhance Aesthetic Outcomes

Abstract: Recession defects frequently involve multiple teeth in one or even both arches. The clinician treating these defects using autogenous connective tissue grafts will usually resort to multiple surgeries due to a belief that insufficient connective tissue material can be harvested from the palate. This program will present surgical modalities that allow clinicians to harvest greater amounts of autogenous connective tissue, thus enabling them to reduce the number of surgical visits for their patients. Participants will learn the possibilities and techniques for harvesting larger connective tissue grafts, recipient site flap design for using these grafts, and the potential risks of these procedures.
