Filter by:The investigators aim to evaluate the biological and mechanical short- and long-term outcome of IL in partially or completely edentulous patients. Moreover, the investigators aim to detect potential influencing risk factors predicting undesirable prosthetic outcome.
Ridge Preservation Comparing the Clinical and Histologic Healing of Flap vs. Flapless Approach to Grafting
The investigators' aim is to evaluate the accuracy of the stereolitographic template comparing the final implant insertion to the planned implant position at coronal and apical level. Clinical relevance: - To identify factors influencing the surgical template imprecision. - To overcome risk factors for surgical template imprecision. - To suggest improvements for highly accuracy of the surgical template especially for immediate loading and avoiding the injury of anatomical structures.
The aim of this study is to determine the clinical success of short implants (6mm) alone and standard implants (10mm) combined with sinus floor elevation in atrophic maxilla.
BACKGROUND: The literature has shown that simplified methods for complete denture fabrication can be as effective as the traditional techniques, but with less expenditure of time and resources, without prejudice to the patients. However, the effectiveness of these simplified methods for patients with more complex medical conditions haven't been deeply explored. OBJECTIVES: To evaluate the effectiveness of a proposed simplified method for complete dentures fabrication for patients with severely resorbed mandibular alveolar bones. METHOD: edentulous patients requesting treatment with bimaxillary complete dentures in a university clinic will be rehabilitated following a simplified technical proposal, being divided randomly into two groups according to the mandibular arch molding technique. In group A, a single impression with alginate through pre-fabricated trays will be performed, while patients allocated in group B will receive a second molding with a more complex technique. After 3 and 6 months, besides important clinical parameters, it will be investigated aspects related to patient's perceptions about the success of treatment. The study will be conducted with a minimum of 30 participants per group, and comparisons between the two groups will be made by means of tests suitable for distribution of data.
In this study a tooth that needs to be extracted will be replaced by an implant (artificial root) placed at the same appointment as the extraction. The investigators want to observe how the gums change shape with healing in two different scenarios: 1. If the soft tissue around your tooth is thin, following extraction and implant placement an extra soft tissue graft (taken from your palate) in the area in order to increase the thickness of your gums after healing. 2. If the soft tissue around your tooth is thick, the implant will be placed without a soft tissue graft. Previous studies have shown that both methods work and can give good results. In fact the two methods are used routinely but they have never been compared objectively to one another in the same research study. The main purpose of this study is to evaluate if there is any difference in terms of esthetic outcomes between these two treatment modalities after a crown has been placed on the implant.
The purpose of this study was to evaluate the effect of a integrated system for inserting two splinted minimally-invasive implants, to retain mandibular over dentures, on the quality of life of edentulous patients.
The purpose of this study is to evaluate validation and clinical assessment of the earlier proposed clinical and radiological classification of the jawbone anatomy in endosseous dental implant treatment. Expected results. - high accuracy of proposed classification for proper implantation risk degree evaluation. - the proposed classification system based on anatomical and radiological jawbone quantity and quality evaluation will be a helpful tool for planning of treatment strategy and collaboration among specialists. - good interobserver reliability of clinical and radiological edentulous jaw segment evaluation. - good reliability between radiological and intraoperative investigations and postoperative data.
The purpose of this study is to compare two different techniques of placing dental implants: 1) removing the tooth and placing the implant immediately and 2) removing the tooth and placing both the implant and a temporary crown immediately. Both procedures currently are accepted methods for replacing missing teeth but direct comparisons of the two procedures are lacking. The results of this study should aid clinicians in selecting the best implant placement technique for their patients.
The aim of this study was to compare the release of the osteoprotegerin (OPG), transforming growth factors (TGF-α), osteocalcin (OCN), osteopontin (OPN), and parathyroid hormone (PTH) during osseointegration of dental implants with and without immediate loading. Forty patients were selected and randomly divided into: Group IM - implant and prosthesis placement within 72 hours; and Group NL - implant insertion and no prosthesis placement during 120 days. Peri-implant crevicular fluid (PICF) was collected immediately after implant insertion and with 7, 15, 30, 60, 90, and 120 days after surgery and were evaluated levels of OPG, TGF-α, OCN, OPN and PTH using Luminex assay. Clinical aspects (Sulcus bleeding and peri-implant probing depth) were also assessed. The data were compared using the ANOVA/Tukey and Friedman/Mann-Whitney tests (α=5%).
