21. Histologic and Clinical Evaluation of a Bioactive Calcium-Phosphosilicate Bone Graft Material in Post-Extraction Alveolar Sockets By Aron Gonshor, Lanka Mahesh, Stephen A. Saroff, Frederic P.C. Joachim
Long-term success of dental implants has been demonstrated when placed simultaneously with or after a socket grafting procedure. Although optimal bone formation can be from 6 to 9 months or longer with grafting materials other than autogenous bone, utilization of bone allograft eliminates patient morbidity through elimination of autograft harvest sites.
35. Reimplantation of Failed Implants: Three Cases of an Unusual Procedure with Five Year Follow Up By Francisco Mesa, Ricardo Muñoz-Martínez, Pablo Galindo-Moreno
Two approaches to the early (preload) osseointegration failure of a dental implant have been described: placement of a new implant after a period of wound-healing, or the immediate insertion of a larger implant. We present the first report of immediate reimplantation at the same site using the same implants, performed in three patients with three different implant brands, which have survived for five years to date. Neither the implants nor the screwretained fixed prostheses have shown any clinical or radiological sign that casts doubt on the success of the reimplantation. It is not our intention to describe a new protocol for cases of implant failure, but rather to report the successful outcome of an unusual approach, using two distinct implant systems, which was adopted in response to the specific requirements of our patients.
47. Atraumatic Extraction of Multi-Rooted Teeth Utilizing the Powertome® Automated Periotome: A Case Series By Dan Holtzclaw, Nicholas Toscano, Jason White
Since their introduction nearly fifty years ago dental implants have revolutionized dentistry, changing the way we approach everything from dentures to single unit crowns. One treatment that has changed considerably with the progression of dental implants is the extraction of teeth. Contemporary dental implant treatment recommends at least 1.0 to 1.5mm of bone surround all aspects of the fixture. To achieve such a goal, preservation of existing bone is essential during tooth removal. This concept has ushered the term “atraumatic extraction.” In this procedure, atraumatic refers to inducing as little damage as possible to the surrounding bone and a number of instruments have been introduced to achieve this goal. Use of very small 15c scalpel blades, periotomes, and piezoelectric surgical units have been documented for atraumatic tooth removal. Recently, an automated version of the periotome has been introduced. The aim of this paper is to demonstrate how the automated periotome is used as an adjunct for atraumatic extraction of multi-rooted teeth.
59. Complication of Inferior Alveolar Canal Perforation During Immediate Implant Placement into a Fresh Mandibular Molar Socket By Dr. Loong T. Yong
This case report illustrates perforation of the superior cortex of the inferior alveolar canal following implant placement immediately into fresh extraction socket of a mandibular molar. The method to prevent this complication is also discussed.
69. Management of Bilateral Severe Gingival Recessions in a HIV Positive Individual with Lateral Sliding Flaps By Shaziya A. Haque, Shilpa Kolhatkar, Crystal McIntosh, Monish Bhola, James R. Winkler
Aggressive tooth brushing and plaque induced inflammation around labially prominent teeth are common reasons for recession. Severe recession defects were present on labially prominent teeth #22 and #27 in a HIV- positive individual.
79. Dental Implants in Children and Adolescents: A Literature Review By Dr. Nivedita Mankani, Dr. Ramesh Chowdhary, Dr. Brajesh A Patil, Dr. Nagaraj, Dr. Poornima Madalli
Edentulism is usually associated with the aging patient. However, total or partial tooth loss also affects young individuals, mainly as a result of trauma, decay, anodontia, or congenital and acquired jaw defects involving the alveolar processes. For elderly patients, the use of oral implants has become an accepted treatment modality for edentulism, and most of today’s knowledge regarding implants is based on such practice. There has been hesitation to perform implant therapy for growing children, hence few children to date have been provided with implant-supported construction. Consequently, little is known about the outcome of the osseointegration procedure in young patients, and until now only a limited number of case presentations have been reported. This article reviews the current literature to discuss the use of dental implants in growing patients and the influence of maxillary and mandibular skeletal and dental growth on the stability of those implants. It is recommended to wait for the completion of dental and skeletal growth, except for severe cases of ectodermal dysplasia.
