Filter by:The objective of this retrospective study with 5-year follow-up was to compare crestal bone loss (CBL) and buccal bone thickness (BBT) around triangular cross-section neck (TN) to round neck (RN) implants retaining mandibular overdentures, using cone-beam computed tomography
Objectives: Inflammatory lesions develop in the tissues surrounding implants are referred to as peri-implant diseases. Oxidants, play a role in inflammatory lesions. The study aimed to determine oxidant and antioxidant levels in the saliva of patients with various levels of peri-implant diseases and the relationship between oxidative stress and peri-implant diseases. Material and methods: Sixty-seven patients with at least one dental implant applied in our clinic were included in the study. The patients were divided into 3 groups; with peri-implantitis (PI), with marginal bone loss (MBL) and with healthy peri-implant (HI) tissues. Twenty-one individuals who didn't have any dental implants were included the study as a healthy control group (HC). For oxidant concentration, total oxidant status (TOS), advanced oxidation protein products (AOPP), and for antioxidant concentration, total antioxidant status (TAS), were investigated.
To report the clinical and radiographic outcomes of implant-supported fixed dental prostheses with full-ceramic cantilever extensions (FDPCs) after a function time ≥ 12 months.
Various risk factors defined in the literature should be eliminated in order for the patient to be able to use implant-supported prostheses for a longer period of time. In the literature, such a diagram for peri-implant risk factors was first described by Heitz-Mayfield in 2020. The scheme that will determine the peri-implant risk diagram is called "Implant Disease Risk Assessment (IDRA)". This tool provides evaluation of various risk factors on a single diagram. In this study, peri-implant risk diagrams will be determined by calling the patients who have previously completed implant treatment in Kütahya University of Health Sciences Faculty of Dentistry Department of Periodontology, and the change in the risk profile assessment will be re-evaluated after the risk factors that can be eliminated are eliminated. In this study, it is aimed to predict the risk of inflammation and alveolar bone loss of the tissues around the implant that may occur in the future in patients who have undergone dental implant treatment, and to evaluate the risk profiles.
Dental implants have become one of the most common treatments used for the rehabilitation of lost teeth. The success rate of dental implant treatment is quite high. One of the criteria used for long-term implant success is the evaluation of radiographic marginal bone loss. Implants are used at the bone and tissue level in implant treatment. In this study, it was planned to use 20 implants of the same brand, with a single implant in the bilateral posterior regions in 10 patients.The study will be designed as split-mouth. The implant will be placed at the bone level with the same protocol in the two edentulous areas and the flap will be closed primarily. After 3 months, the substructure of the two-piece abutment concept system will be placed in a region during the healing head placement stage, and the bone level implant will be converted to the tissue level. A conventional healing cap will be placed in the other area. Periapical radiographs will be taken from the patients who participated in our study, as in all implant patients, during the pre-surgical planning phase and after implant placement. With the control periapical radiographs to be taken as a result of one-year follow-up, the marginal bone loss amount in the implants will be evaluated using soft-ware. Clinical measurements will be taken in all patients at the prosthetic loading session and 1 year after loading.
Immediate implant placement has been advantageous in terms of reduced treatment time and fewer surgical interventions. Given the fact that the level of buccal bone acts as a major prognostic factor for IIP, the indications for immediate implant placement were suggested to be limited to intact alveolar sockets.In recent years, many attempts have been performed to compensate for the alveolar ridge resorption in immediate implant placement in compromised sockets. The clinical outcomes of IIP with guided tissue regeneration and connective tissue grafting using papilla preservation technique in compromised extraction sockets has not been previously reported.
The impact of smoking on dental implant failure has been a constant topic of discussion for the past decade and the current literature confronts the inconclusive evidence of tobacco for a marginal bone loss risk factor. The aim of the present investigation is to determine the association between tobacco and marginal bone loss or implant failure in a sample of patients who had received implant-supported restorative therapy in the Dentistry Hospital of the University of Barcelona (Campus of Bellvitge). Considering that peri-implant marginal bone is essential for dental implant success, in this study we would like to establish the relationship between marginal bone loss around implants and smoking, in our own population study, in order to improve the prognosis of implant success in smoking patients. On the other hand, knowing the negative effect tobacco has on marginal bone loss in dental implants, we will be able to better predict peri-implant bone loss and reveal the probability of implant failure in short and long-term in smokers. By informing the patient correctly, we can raise awareness and create an additional reason for them to stop smoking, or at least reduce the number of cigarettes they smoke per day.
A post-market, randomized-controlled, superiority clinical study to compare medium-term performance and safety of the Straumann PURE 2-piece Ceramic Implant with Straumann Bone Level Implant using a fully digital workflow.
Objectives: The aim of this study was to evaluate in a cohort of patients with peri-implant mucositis: (a) the efficacy of professional mechanical debridement therapy assisted using Bioptron Hyperlight Therapy on the reduction of periodontal indexes (b) the reduction of total oxidative salivary stress. Material and Methods Forty subjects with a diagnosis of peri-implant mucositis were enrolled in this study and randomly assigned to the study group (mechanical debridement therapy assisted using Bioptron Hyperlight Therapy) or control group (mechanical debridement therapy alone). The study duration was 6 months. Data on plaque index (PI), bleeding on probing (BoP), probing pocket depth (PPD) and pain relief on Visual Analogue Scale (VAS) were recorded at T0, T1 (14 days), T2 (1 month) and T3 (6 months). Group differences were assessed using Student's t-test and Pearson's Chi-squared test of homogeneity
After a single-tooth extraction, physiological remodeling processes are unavoidable which leads to a total loss of the periodontal ligament and resorption of the bundle bone. Immediate implant placement associated with bone substitutes and customized healing abutments seems to reduce the amount of resorption at peri-implant areas. Recently, studies evaluating the use of a connective tissue grafts are being conducted in order to assess possible final outcome advantages in immediate implant procedures. This study aims to evaluate peri-implant tissue dimensional changes after the use of a customized healing abutment with or without connective tissue graft in flapless maxillary immediate implant placement.
