Filter by:The microthreaded and platform switched implants could control the stress in the suitable range. The splint would disturb the function. So it is necessary to know whether the splinted single-unit crowns is fit for the adjacent multi-implants. Outcome variables: Splinted single-unit crowns on one side implants and non-splinted single-unit crowns on the other side Materials and method: 80-100 consecutive implants in at least 20 patients would be included for implant- supported restorations in the posterior maxilla or mandibular. All patients would be in general good health. For every patient, the same posterior teeth had lost on both sides for more than 6 months. All patients were treated by the same qualified surgeon. Prosthetics procedure would be performed by an experienced prosthodontist. The two sides were allocated to the test or the control group according to the predefined computer-generated randomization table. Clinical evaluations and radiographic analysis were performed by an oral and maxillofacial radiologist who was not aware of the type of Prosthetics technique that was used.
The aim of this prospective cohort study is to compare the esthetic, clinical and patient-centered outcomes following immediate and delayed implant placement protocols.
Ridge Preservation Comparing the Clinical and Histologic Healing of Membrane vs. no Membrane Approach to Grafting.
The main purpose of the present study is to evaluate the dental implant placement using two different CBCT-derived templates and to study the related factors that affect accuracy so as to support the further clinical application of the technique. Thirty patients with partial edentulous denture are recruited. They are randomized to two groups. A radiographic guide is prepared before CT/CBCT scan. The CT/CBCT scan DICOM files are loaded in a planning program and converted into 3D computer images. A surgical template is fabricated through this virtual planning. After 6 weeks, if the implants are judged stable, the patient has the option of replacing the fixed prosthesis. Patients are recalled for oral hygiene maintenance and prosthetic controls every 6 months for the entire duration of the study.
To investigate the prevalence and risk factors for peri-implant disease in partially edentulous patients rehabilitated with implants supported crown or bridge so as to provide evidence for clinical prevention and control.
To investigate the patient-related risk factors for peri-implant disease in partially edentulous patients rehabilitated with implants supported crown or bridge so as to provide evidence for clinical prevention and control.
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 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.
