Filter by:This study will identify and enroll patients already scheduled to receive guided maxillary implant placement with palateless overdenture. Standard clinical practice will be followed for this multi-stage process. The study purpose is to evaluate the degree of satisfaction during the standard progression in order to determine at which post edentulous stage patients achieve maximum satisfaction using the Oral Health Impact Profile 49 (OHIP 49).
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.
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 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%).
Patients with an edentulous mandible restored with implants who have participated in the core study CR 04/07 will be recruited for this extension study. No further interventions will be made for this extension study other than a clinical follow-up examination and questionnaires. Patients will not receive an investigational treatment in this study. Patients will be followed at 5 to 10 years from the date of the original implant loading
Purpose: The aim of this study was to analyze the clinical and radiographic outcomes of 23 edentulous jaws treated with 3D software planning, guided surgery, immediate loading and restored with Cad-Cam Zirconia and titanium full arch frameworks. Material & methods: This study was designed as a prospective clinical trial. Twenty patients have been consecutively rehabilitated with an immediately loaded implant supported fixed full prosthesis. A total of 120 fixtures supporting 23 bridges (8 mandible, 15 maxilla) were placed , 22 of which in fresh post extraction sockets. All the implants were inserted with an insertion torque of 35/45 Ncm. 117 out of 120 implants were immediately loaded the other 3 were delayed loaded. Outcome measures were implants survival, radiographic marginal bone-levels and bone remodeling, soft tissue parameters and complications.
The primary objective of this study is to demonstrate non-inferiority of the Straumann Bone Level Ø 3.3 mm NC SLActive Roxolid Implants compared to Straumann Bone Level Ø 4.1 mm RC SLActive Roxolid Implants based on mean crestal bone level changes measured between surgery and 12 months post-implant placement. The secondary objectives will assess differences in clinical outcomes between the test and control implants, including implant success and survival, gingival recession, subject satisfaction and additional early bone level measurements.
