Site Preservation with Placental Membrane

19. The Use of DynaMatrix® Extracellular Membrane for Gingival Augmentation and Root Coverage: A Case Series By Stephen Andrew Saroff

Over the years, mucogingival surgery has developed into an integral part of periodontal therapy. Mucogingival defects and deformities are conditions that deviate from the normal anatomic relationship between the gingival margin and mucogingival junction. Some of the most common conditions are gingival recession, an absence or insufficient amount of keratinized tissue, and the presence of probing depths extending past the mucogingival junction. A common factor is, often, the existence of alveolar bone loss. However, in spite of the many advances made in surgical techniques and materials, the coverage of denuded root surface has primarily focused on the soft tissue and not on the underlying bone loss. This article presents a series of cases illustrating techniques that have yielded favorable surgical outcomes in challenging circumstances involving the incorporation of allogeneic bone putty and an extracellular matrix scaffold into the process of repair and reconstruction.

35. BioXclude™ Placental Allograft Tissue Membrane Used in Combination with Bone Allograft for Site Preservation: A Case Series By Dan Holtzclaw, Nicholas Toscano

Site preservation entails conservation of existing bone during tooth removal and augmentation of the tooth socket. A variety of materials may be used to augment the socket including bone allograft, xenograft, calcium sulfate, beta-tricalcium phosphate, collagen sponges, and growth factors such as platelet rich fibrin. To contain these materials within the socket and protect them from the oral cavity, barriers such as non-cross linked collagen plugs, cross linked collagen membranes, chitosan plugs, expande poytetrafluoroethylene (PTFE) membranes, and connective tissue grafts are often used. BioXclude™, a resorbable amnion chorion membrane, has recently been introduced as a new barrier for site preservation. This case series documents use of BioXclude™ amnion chorion membrane for the purpose of site preservation.

55. Decoronation for Ridge Preservation in Implant Dentistry: A Clinical Technique and Case Report By Tareq Abu-Saleh

Several methods have been advocated to compensate for bone loss in anterior maxilla and achieve satisfactory esthetic results in implant treatment. Some of these modalities are considered time consuming, technique sensitive, expensive, and unpredictable.

69. Neck Dissection for Oral Cancer By Fayette C. Williams, Brent B. Ward, Sean P. Edwards

Cancer of the oral cavity and oropharynx strikes over 35,000 patients each year in the United States. At least one-third of these patients will present with metastases to the neck. The status of the cervical lymph nodes remains the strongest prognostic indicator for oral cancer. Appropriate diagnosis and management of the neck is critical in the success of oral cancer treatment.
