The use of MTA in Clinical and Surgical Endodontics
LOD-082-00
Dr. Arnaldo Castellucci
Recently, Dr. Mahmoud Torabinejad of Loma Linda University, California, has developed a new cement named Mineral Trioxide Aggregate which appears to have all of the characteristics requested of the ideal cement to seal pathways of communications between the pulp and the oral cavity (mechanical and carious pulp exposures), and between the root canal system and the periodontium (iatrogenic perforations, open apices, resorbed apices, root-end preparations).<br><br>MTA is an endodontic cement that is extremely biocompatible, capable of stimulating healing and osteogenesis, and is hydrophilic. MTA is a powder that consists of fine trioxides (Tricalcium oxide, Silicate oxide, Bismute oxide) and other hydrophilic particles (Tricalcium silicate, Tricalcium aluminate, responsible for the chemical and physical properties of this aggregate), which set in the presence of moisture. Hydration of the powder results in formation of a colloidal gel with a pH of 12.5, that solidifies to a hard solid structure in approximately three-four hours. This cement is different from other materials currently in use because of its biocompatibility, antibacterial properties, marginal adaptation and sealing properties, and its hydrophilic nature.<br><br>The characteristic that distinguishes MTA from other materials used to date in endodontics is its hydrophilic properties. Materials used to repair perforations, to seal the retro-preparation in surgical endodontics, to close open apices, or to protect the pulp in direct pulp capping, are inevitably in contact with blood and other tissue fluids. Moisture may be an important factor due to its potential effects on the physical properties and sealing ability of the restorative materials. As shown by Torabinejad et al., MTA is the only material that is not affected by moisture or blood contamination: the presence or absence or blood seems not to affect the sealing ability of the mineral trioxide aggregate.<br><br>During the presentation, several cases of treatment with MTA will be showed. Aim of the presentation is to show the indications and the technique for the correct use of this relatively new material: how to seal an open apex, how to repair a strip-perforation under the microscope, how to protect a pulp exposure to perform a direct pulp capping, how to use MTA during surgery to seal the retroprep.<br><br>In conclusion, the viewers should be able to appreciate the advantages of this material, which made our treatments more predictable and gave us the possibility to save teeth otherwise condemned to extraction.

Minimally Invasive Soft Tissue Augmentation
LOD-067-00
Dr. Homa H. Zadeh
A variety of techniques have been described for augmentation of soft tissue around teeth with varying donor material and access. Recently, tunnel technique has been used for minimally invasive assess to sites being augmented. This presentation will describe a novel access for soft tissue augmentation and root coverage. Moreover, application of autogenous tissue, as well as growth factors will be discussed. Minimally invasive soft tissue augmentation may also be applied for modification of thin biotypes around dental implants. The techniques described will be illustrated with clinical cases.
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
LOD-063-00
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.
