Filter by:Soldiers operate in environments that are more likely to lead to oral trauma, risking poor dentition which can directly impact military readiness. Dental restoration can often be accomplished via dental implant insertion. Microbiome-associated complications that result in bone loss, including the micro-leakage of bacterial species proliferating in the dental implant internal cavity, frequently lead to implant failure. Reduction in implant bacterial load may result in a shift of the composition of the microbiome in favor of less pathogenic species, potentially improving dental implant success rates, reducing surgical revisions, and associated cost savings. This study aims to determine how disinfectant gel (hydrogen peroxide or chlorhexidine) insertion into dental implant internal cavities affects implant failure rates, bacterial load and microbiome composition.
The aim of this study will be to compare the long-term outcomes of sandblasted and acid-etched (SLA) implants in patients previously treated for periodontitis and in periodontally healthy patients (PHP) after a follow-up of at least 20-years.
Implant retained overdentures are a cost-effective treatment for elderly patients suffering from complete tooth loss. Despite the high success rate of implants in the general population, older adults lacking all teeth are a challenging population for implant therapy, often presenting limited bone disponibility, narrow alveolar ridges, diminished bone density, scarce inserted gingiva and several co-morbidities.Thus, improving their possibility of success in implant therapy avoiding further surgical interventions is key. Platelet-rich fibrin (PRF) is a blood derivate that can be easily and economically obtained from patients and that has shown promise of reducing the complications and improving the success of implant therapy, nevertheless its benefits in patients receiving implant retained overdentures has not been stablished. It is possible that PRF can improve the results and diminish the complications of implant therapy in older adults. The investigation aims to demonstrate that the use of platelet-rich fibirn (PRF) is safe and beneficial for implant treatment in older adults suffering from complete tooth loss.
Introduction: In order to minimize postoperative morbidity and failures of dental implant therapy, several antibiotic regimens have been proposed in the literature. However, the extensive use of antibiotics in health care has been debated due to the adverse effects and bacterial resistance. Furthermore, the impact of preoperative antibiotics on peri-implant bone level is still not clear. Objectives: The primary objective of this study will be to assess whether giving preoperative antibiotics (azithromycin 500mg) after implant placement over 7 days will influence peri-implant crestal bone levels after 4 months in healthy patients undergoing platform-switched implant placement. The secondary objectives will be to evaluate postoperative pain severity, surgery-associated morbidities, and 1-year implant survival rate. Methods: Fifty individuals will be recruited in a double-masked 2-arm randomized clinical trial. Participants in the intervention group will receive 500mg of azithromycin 1 hour before implant placement. Participants in the control group will take one placebo 1 hour preoperatively. The changes in mesial and distal crestal bone level (primary outcome) will be measured at baseline and 4-month follow-up using standardized periapical radiographs. Pain severity and surgery-associated morbidities (secondary outcomes) will be evaluated by clinical examinations and self-administered questionnaires. Implant survival rate will be assessed at the 1-year follow-up. Descriptive and bivariate analyses will be used to analyze the data. A P value ≤ 0.05 will be considered statistically significant. Clinical relevance: This study will be the first placebo-controlled double-blinded randomized clinical trial studying the effect of preoperative azithromycin on radiographical, clinical and patient-based outcomes after implant surgery. This type of design will reduce as much as possible the risk of bias and increasing the quality of evidence. The results from this study might help provide guidelines for clinicians that will optimize implant survival rate while decreasing antibiotics exposure to patients undergoing straightforward implant surgery.
The purpose of this randomized controlled trial is to compare clinical data and implant stability of immediately loaded TSIII Osstem implants with Sandblasted and Acid-etched (SA) surface versus implants with SA surface modified with pH buffering agent for the rehabilitation of single implant-supported crown.
This study designed as a randomized controlled split-mouth trial will be conducted at the Dental Clinic of the University of Valencia. The aim will be to assess differences in clinical, radiological and microbiological outcomes between implants with 2 different connections: internal hexagon and conical connection. Following the premises, to minimize the bias related to prosthetic phase and maximize the effect of connections on MBL changes, a 1abutment-1time protocol will be used. The study hypothesis is that there will be no statistically significant differences between both implant connections.
This study evaluates the success rate, as the biological and prosthesis complications, of posterior single-unit implants immediately loaded with a chair side Computer-Aided Design and Manufacturing (CAD-CAM) composite crown, after a follow-up period of 6 months,1,2,3,4 and 5 years. Complementary ex vivo analyses will be performed to evaluate the wear of restorations. The time and cost benefit of the presented digital workflow, as patient centered outcomes will also be evaluated.
