Platelet concentrates for surgical use are innovative tools of regenerative medicine, and were widely tested in oral and maxillofacial surgery. Unfortunately, the literature on the topic is contradictory and the published data are difficult to sort and interpret. In bone graft, implant and reconstructive surgery, the literature is particularly dense about the use of the various forms of Platele...

Purpose: Attachment of bacteria to titanium may differ not only between bacterial species but also between strains within a species. The aim of the present in vitro study was to examine differences in bacterial attachment using 4 gram-negative anaerobic species of bacteria that are considered potential periodontal pathogens. Materials and Methods: The attachment of clinical and laboratory strai...

Purpose: Implant length, implant surface area, and crown-to-root (c/r) ratio and their relationship to crestal bone levels were analyzed in 2 groups of partially edentulous patients treated with sintered porous-surfaced dental implants. Materials and Methods: One hundred ninety-nine implants were used to restore 74 partially edentulous patients with fixed prostheses. Implants were categorized a...

AIMS To examine and compare mortality rates in patients treated with oral and implant naltrexone. DESIGN A retrospective cohort study. SETTING A community not-for-profit drug treatment clinic. PARTICIPANTS Patients treated with oral naltrexone (n = 2155, 17 207 patient-years) and implant naltrexone (n = 2389, 11 678 patient-years) for problematic opiate use between August 1997 and Decembe...

PURPOSE To determine the number of bisphosphonate-associated cases of dental implant failure in South Australia. MATERIALS AND METHODS All general and specialist dentists who place dental implants in South Australia were contacted and asked to provide information on the total number of implants placed over the decade to December 2007. Cases of bisphosphonate-associated implant failure were id...

Biofilms are complex microbial communities that grow on various surfaces in nature. The oral micobiota tend to form polymicrobial biofilms, particularly on the hard mineralized surfaces of teeth, which may impact on oral health and disease. They can cause inflammation of the adjacent tooth-supporting (periodontal) tissues, leading to destructive periodontal disease and tooth loss. The emergence...

Regenerative medicine and tissue engineering technologies have greatly benefitted medicine and dentistry over the past years (Zaky & Cancedda 2009). The use of protein-, geneand stem cell-based therapeutics have been exploited significantly in the reconstruction of new tissues and organs (Discher et al. 2009). The field of oral and periodontal regenerative medicine has undergone significant rec...

Endosseous cementless implants are widely used in orthopaedic, maxillofacial and oral surgery. However, failures are still observed and remain difficult to anticipate as remodelling phenomena at the bone-implant interface are poorly understood. The assessment of the biomechanical strength of the bone-implant interface may improve the understanding of the osseointegration process. An experimenta...
