NCT07304752
Evaluate whether the type of probe (plastic vs. metallic) modifies the accuracy of peri-implant probing in single-unit implants, by comparing the probing depth recorded with the prosthesis in place versus without the prosthesis (ΔPD, mm). Secondarily, explore the influence of prosthetic design and implant position on probing values and on other clinical and radiographic parameters.
NCT07300657
Background: Dental implant therapy is a well-established and predictable procedure for replacing missing teeth, with high long-term survival rates. However, poor oral hygiene remains one of the main modifiable risk factors for peri-implant diseases such as mucositis and peri-implantitis. Objective: The aim of this randomized controlled clinical trial is to evaluate the effectiveness of an artificial intelligence (AI)-based chatbot, developed and validated by dental experts, in improving oral hygiene and clinical outcomes in patients with implant-supported restorations, compared to traditional educational methods such as printed leaflets and dental hygienist sessions. Methods: A total of 110 adult patients rehabilitated with dental implants were randomly assigned to either an AI chatbot intervention group or a control group receiving standard oral hygiene education. The chatbot provides continuous, personalized education and motivation through natural language interaction. Clinical and radiographic parameters, including plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and marginal bone loss (MBL), were recorded at baseline and at follow-up visits. Expected outcomes: It is hypothesized that the use of an AI-based chatbot will significantly improve oral hygiene compliance and clinical outcomes compared to conventional methods. Significance: The study aims to demonstrate the potential of AI-assisted patient education in promoting long-term peri-implant health and preventing peri-implant diseases.
NCT07295743
The study was conducted at the Division of Periodontology, Bolu Abant İzzet Baysal University Faculty of Dentistry. Participants were systemically healthy individuals aged 18 to 70 who had received dental implant prostheses within the past five years and had high-quality panoramic radiographs. The peri-implant status of the subjects was evaluated using various indices and radiographic analyses in accordance with Chicago's Classification of Periodontal and Peri-Implant Diseases and Conditions. Additionally, measurements of gingival thickness, gingival phenotype, keratinized gingival width, and emergence angle were performed.
NCT07196293
The study focuses on the critical role of the gingival emergence profile in the success of dental implants, emphasizing its importance for both peri-implant health and esthetics. The research aims to evaluate and compare the effectiveness of two common, cost-effective dental materials-light-cure composite and Protemp (a bis-acryl composite resin)-for fabricating customized healing abutments. By assessing the peri-implant tissue response to these materials, the study seeks to determine which is more suitable for creating an optimal, natural-looking soft tissue contour, thereby providing dentists with a practical and reliable alternative to more expensive options like PEEK.
NCT06967649
The success of rehabilitation with osseointegrated implants is associated with numerous factors, including patient characteristics, installed implants, proper planning, and the prosthetic connections used. In the long term, success is closely related to the clinical radiographic follow-up of the implanted region and the identification of intrinsic or extrinsic factors that may interfere with implant survival. Therefore, the objective of this study is to evaluate, through clinical and radiographic analysis, the peri-implant tissues and prosthetic connections of research participants rehabilitated with osseointegrated implants at the Implant Dentistry Clinic of the Federal Fluminense University, over a period of 5 years. This will be a double-blind longitudinal study. A total of 148 research participants will be selected, respecting the inclusion criteria: completion of surgical-prosthetic planning by the Implant Dentistry Clinic team at UFF, including osseointegrated implants and prosthetic components manufactured by SIN Implant System (São Paulo, Brazil); agreeing to and signing the informed consent form, being willing to be monitored for a period of 5 years; systemically healthy patients who do not use antiresorptive and antiangiogenic drugs; patients with a plaque index \<20% (Ainamo \& Bay 1975) and bleeding on probing \<20% (Muhlemann \& Son 1971) at the start of the study. Participants will undergo clinical and radiographic analysis of peri-implant tissues and prosthetic connections at the following intervals: up to 7 days after implant installation (Time 0), at the time of prosthesis installation (Time 1), 6 months after prosthesis installation (Time 2), and 1 to 5 years after prosthesis installation (Times 3, 4, 5, 6, and 7, respectively). It is expected that this longitudinal study will lead to a better understanding of the factors influencing peri-implant bone loss and long-term success.
NCT06761521
68 patients underwent the aMMP-8 chair-side test as well as clinical traditional measurement methods. Those who had one or more implants in their mouth were selected as patients. The condition of the attachment tissues of these implants is monitored at a control visit after five years.
NCT06128850
Except for patients with referred clinical bruxism and uncontrolled medical conditions, the study included 123 implants with implanted fixed prostheses that had lasted at least six months after functional prosthetic loading. In all implant patients, the health scale ranged from implants and natural teeth to plaque, gingival index, bleeding in the probe, mouth depth, loss of clinical attachment, and dental implants. The health and illness of the implants have been determined. Patients were divided into three groups: peri-implantitis, peri-implant mucositis, and peri-implant health. Inclusion Criteria: * Patients between the ages of 18- 70 * Drugs that have a systemically healthy and controlled treatment situation * Drivers who have implant-supported fixed prostheses that have been at least six months after functional prosthetic loading Among these groups, it was checked whether periodontitis was seen in patients with peri-implantitis, gingivitis in patients with peri-implant mucositis, and whether healthy gums were seen in individuals with peri-implant health. To determine the health and disease status of individuals' implants, plaque index (Silness Loe 1964), gingival index (Loe Silness 1963), bleeding on probing (Ainoma Bay 1975), pocket depth measurements, and clinical attachment level were collected.
