Book Description
Background: Despite the ongoing debate about the meaning of keratinized gingiva, most papers agree that a sufficiently broad band of keratinized tissue exert a positive effect on long-term prognosis and maintain of dental implants.The recent introduction of xenogenic collagen matrixes further expanded the clinical alternatives in the management of soft tissues healing during pre-implant or peri-implant regenerative procedures.Aim: The aim of this prospective cohort study is to test the performance of a new xenogenic collagen matrix (Mucodermu00ae, Botiss Dental, Germany) as a socket sealing material, to allow second-intention healing of post-extractive sockets filled with a xenogenic bone substitute or with an immediate submerged implant.Materials and Methods: 10 patients (4 males and 6 females - mean age: 53.2 years) were recruited, presenting with a single-rooted tooth scheduled for extraction, because of unsalvageable endo-perio lesions or vertical root fractures.After atraumatic tooth removal, the post-extractive alveolus received either a socket preservation procedure or an immediate submerged implant. Demineralized bovine bone mineral integrated in a 10% collagen matrix (Bio-Oss Collagenu00ae, Geistlich Pharma, Switzerland) was used as a socket preservation material or to fill the gap between the implant surface and the bony walls of the alveolus.In both cases, the gingival margins of the alveolus were sealed with a xenogenic collagen matrix (Mucodermu00ae, Botiss Dental, Germany). Through 5/0 monofilament sutures, the matrix was gently stabilized subperiosteally under the palatal and buccal gingival margins of the socket for 2/3 of its surface, whether 1/3 remained exposed for second intention healing.The following parameters were evaluated: a) exposed surface of the matrix at the end of surgery (T0);b) soft tissue healing at 1, 4, 6, and 8 weeks from surgery (T1-4);c) aesthetic performance provided by the socket sealing material, quantified deriving the colorimetric score u2206E between the regenerated site and the surrounding gingiva, 8 weeks after surgery (T4);d) histological aspect of gingiva samples, harvested 20 weeks after surgery (T5) from the regenerated area.Results: a) the mean postoperative exposure area of the matrix was 26,25 mm2 (14,2 to 38,84 mm2); b) 8 weeks after surgery (T4), full wound closure was achieved in 9 out of 10 sites with healthy keratinized tissue. A single patient (#3) did not achieve full wound closure at T4, starting from the highest postoperative matrix exposure rate of the cohort (38,84 mm2); c) the mean colorimetric score u2206E between the regenerated site and the surrounding gingiva at T4 was 3,76 (3 to 6,55). Seven out of 10 patients reported an excellent aesthetic integration of the matrix (u2206E score

Book Description
In their contribution to the first edition of this Handbook, entitled "The Teeth," LEHNER and PLENK (1936) discussed the tissues constituting the "perio dontium" rather briefly. In contrast to the detailed paragraphs dealing with, for example, enamel and dentine, the section (about 40 pages and 20 illustra tions, mostly drawings) devoted to periodontal tissues failed to provide a factual review and summary of the contemporary knowledge and latest developments in research on the various components of the periodontium. Instead, much of the text was an attempt to arrive at conclusions from often purely semantic speculations, playing the various schools of thought against each other, provid ing arguments in favor of the authors' views and arguments for the feasibility and probability of accepting or rejecting the often diverse opinions, while the reader was referred to the already existing literature for factual details. Since 1936, however, factual details ofthe structural biology of the periodon tal tissues, i. e. their development, structure, function, and physiology, have been greatly extended and have been internationally accepted. With much less opin ionated belief to cope with, this knowledge has formed the solid foundation upon which diagnosis, prevention, and treatment in the fields of clinical perio dontology, modem orthodontics, and re- and transplantation procedures of teeth have been built.

Book Description
This book presents a multidisciplinary evidence-based approach to the management of teeth with lesions of endodontic-periodontal origin. The book opens by addressing the etiology and classification of endodontic-periodontal lesions, and demonstrates its relevance to the daily practice. Specific endodontic, prosthetic, and periodontal considerations that should be incorporated into clinical decision making and treatment planning are then discussed in detail. Subsequent chapters describe modern clinical procedures in periodontal regenerative treatment, describe vertical root fractures as an endodontic-periodontal lesion, examine treatment alternatives following the extraction of teeth with endodontic-periodontal lesions, and discuss possible biological complications in implant supported oral rehabilitation. Finally, a summary chapter considers the integration of clinical factors and patient values into clinical decision making. The text is accompanied by many figures presenting informative clinical examples. The authors are internationally renowned scientists and clinicians from the specialties of Endodontology, Periodontology, and Oral Rehabilitation. Owing to its multidisciplinary and comprehensive nature, the book will be relevant and interesting to the entire dental community.

Book Description
Long acting injections and implants improve therapy, enhance patient compliance, improve dosing convenience, and are the most appropriate formulation choice for drugs that undergo extensive first pass metabolism or that exhibit poor oral bioavailability. An intriguing variety of technologies have been developed to provide long acting injections and implants. Many considerations need to go into the design of these systems in order to translate a concept from the lab bench to actual therapy for a patient. This book surveys and summarizes the field. Topics covered in Long Acting Injections and Implants include the historical development of the field, drugs, diseases and clinical applications for long acting injections and implants, anatomy and physiology for these systems, specific injectable technologies (including lipophilic solutions, aqueous suspensions, microspheres, liposomes, in situ forming depots and self-assembling lipid formulations), specific implantable technologies (including osmotic implants, drug eluting stents and microfabricated systems), peptide, protein and vaccine delivery, sterilization, drug release testing and regulatory aspects of long acting injections and implants. This volume provides essential information for experienced development professionals but was also written to be useful for scientists just beginning work in the field and for others who need an understanding of long acting injections and implants. This book will also be ideal as a graduate textbook.
