Tissue Engineering for Hard and Soft Tissue Regeneration - Clinical and Applied Results

LOD-064-00

Dr. E. Todd Scheyer

The promising field of periodontal tissue engineering, barely a decade old, is likely to revolutionize Periodontics. Cell based man-made skin, the first commercial product of tissue engineering, is already on the market and other variations will soon join it. Recombinant technology has provided us the first fully synthetic powerful growth factor available in periodontics with r-PDGF-BB which has been critically evaluated in all areas of periodontal research. This course will provide an overview of biologically based and live cell based tissue substitutes. Results from human and animal studies using biomimetics and tissue engineering to facilitate root coverage and bone formation will be discussed and human histology will be reviewed. Expanded clinical applications of growth factor influenced wound healing in tissue regeneration will also be presented.

Current trends in Aesthetic Periodontology

Dr. Andre Saadoun

Nowadays, the goal of periodontal plastic muccogingival procedure is to perform surgery as atraumatically as possible at the recipient and donor site. Recently, as an alternative to autogeneous gingival graft in root coverage procedures, Enamel Matrix Derivative and acellular dermal matrix allograft were utilized to correct this gingival defect, negating the requirement for a second surgical site.

YSGG Laser Precision in Periodontal Plastic Surgery

LOD-059-00

Dr. Bobby Butler

Lasers have been used in dentistry for many years. Mostly they have been used with soft tissue procedures. Recently the Er,Cr:YSGG laser has been shown to be safe and effective in osseous procedures. Many cosmetic dentists have been using lasers for esthetic crown lengthening procedures, but most of these cases are simple gingivectomies and not true crown lengthening procedures. Complications can occur without understanding the biologic width and different periodontal biotypes. This presentation will discuss current and future applications with the Er, Cr: YSGG laser with periodontal surgical procedures. The focus will be its use in closed and open esthetic crown lenghtening procedures. Discussion with case selection and osseous biotypes with be stressed. Other applications involving osseous augmentation procedures, harvesting osseous blocks, ridge splitting and lateral sinus wall procedures, will also be briefly discussed.

Bone Morphogenetic Proteins, A Realistic Alternative to Bone Grafting<br>

LOD-054-00

Dr. Ulf Wikesjo

Surgical placement of oral implants is governed by the prosthetic design and by the morphology and quality of the alveolar bone. Often, implant placement may be difficult, if at all possible, due to alveolar ridge aberrations. In consequence, prostheticly dictated implant positioning commonly entails bone augmentation procedures. One objective of our laboratory is to evaluate the biologic and clinical potential of bone morphogenetic proteins (BMPs) including rhBMP-2, rhOP-1/rhBMP-7, rhGDF-5, other candidate biologics, bone biomaterials, and devices for alveolar ridge augmentation and implant fixation. This presentation will discuss the unique biologic potential, the clinical relevance and perspectives of BMP technologies for alveolar bone augmentation and oral implant fixation, in particular the development of a unique bone-inductive oral implant. This presentation will also address merits and explain short-comings of current treatment protocol including bone biomaterials and guided bone regeneration (GBR). BMPs have an unparalleled potential to augment alveolar bone and support implant osseointegration and long-term functional loading. Inclusion of BMPs for alveolar augmentation and osseointegration will not only enhance predictability of existing clinical protocol but radically change current treatment paradigms. Inclusion of the bone-inductive oral implant in the treatment panorama may make 'grafting' and GBR procedures altogether obsolete.

Perio-Prosthetic Considerations Around Dental Implants<br>This course will discuss surgical and restorative concepts, procedures and solutions to improve the soft tissue emergence profile of implant and pontic sites in single implant restorations and implant bridges. The restorative choice of implant design and abutment material will be discussed and particularly the evidence of using Zirconia abutments as stable base for soft tissue esthetics and long term implant results.<br><br>The concept of using a concave or flat preplanned abutment via the cad-cam route and via the prefabricated route will be discussed and the steps preventing removal of abutments during the restorative phase.<br><br>This course will teach the restorative dentist the new concepts of zirconia abutment materials, the concave or flat abutment design and the immediate or early placement of the final abutment.

Endodontic Access and Negotiation - Breaking & Entering

LOD-038-00

Dr. L. Stephen Buchanan

Technological advances in shaping and filling root canal systems have resulted in extremely consistent and ideal outcomes making those procedures more science than art form. However, cutting access cavities, finding all the canals in a tooth, and negotiating them to their full apical extents still requires developed skills and careful attention to detail. Ironically, many clinicians consider the access preparation and root canal negotiation those things we do to get to the important stuff afterwards this is ironic because when a mistake occurs during these initial phases in treatment it is often impossible to recover. Loss of structural integrity, perforations, missed canals, blocked canals, ledged canals and broken files are just some of the negative outcomes that occur when access and negotiation procedures go awry.<br><br>With adequate radiographs, the right access instruments, ultrasonic handpieces, lubricants, apex locators, and a predictable negotiating technique, artful outcomes can and should be the expected result when we head into a root canal space. Dr. Buchanan will show, in a step-by-step manner, the concepts, instruments, and techniques needed to set the stage for endodontic success using CT reconstructions of endodontic anatomy, video footage shot through an operating microscope, and radiographs of clinical cases.

Endo or Implant - Rational decision making from an Endodontist's viewpoint

LOD-029-00

Dr. L. Stephen Buchanan

As an Endodontists who places implants, Dr. Buchanan presents a uniquely balanced argument for when to save teeth with endodontic therapy and when the patient will be better served by replacement of the tooth with an implant. Dr. Buchanan will first explain the procedural advances available from endodontic specialists to save many teeth previously thought to be unsalvageable, including microsurgery, MTA root repair material, ultrasonics, and state-of-the-art shaping, cleaning, and 3D obturation technology. Then he will discuss how the structural integrity of roots greatly affects the long term prognosis of endodontically-treated teeth and methods for maintaining the inherent strength of teeth being saved with RCT. Finally, Dr. Buchanan will explore the advantages and satisfaction of a multi-disciplinary approach to treatment planning with an emphasis on the new trend of endodontists to view themselves as understructure specialists.

Periodontal Plastic Surgery for Natural Teeth and Implants

LOD-026-00

Dr. Henry Takei

The last decades has witnessed tremendous emphasis on the esthetic aspect of dentistry. The gingival tissues which frames the dentition is an integral part of 'Dental Esthetics'. The clinician must have a good biologic and clinical understanding of both the teeth and gingival tissue in order to attain a healthy and esthetic result. Correcting gingival recession, root exposure, loss of papilla, which leads to poor gingival symmetry, is of major importance in achieving an esthetic outcome. In addition, the emphasis on implants in the esthetic zone requires sound surgical principles to achieve an optimal gingival emergence profile around an implant restoration.
