View clinical trials related to Missing Teeth.
Filter by:The purpose of this clinical trial is to evaluate and compare bridges to replace one or two missing teeth in the mouth. The bridges will be made of two variants of ceramic material. We will evaluate the bridges for up to five years regarding technical and biological complications.
Sixteen dental implants inserted in sixteen patients who were selected from the outpatient clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University, for the rehabilitation of missed single maxillary posterior tooth by an immediately loaded dental implants
This study aims to evaluate the changes in the stability of implants of the same macro-design placed with particle grafting in the fresh extraction socket, without grafting and placed in healed implant sites.
Loss of teeth leads to loss of function and lack of normal alveolar growth, along with unpleasant esthetics that hamper the psychosocial development of the young child. Traditionally, the management of single tooth loss in a young child is done by conservative means. The presence of large pulp chambers in incompletely mineralized immature teeth of children predisposes the pulp to loss of vitality in cases of complete coverage restorations . Hence, the clinician resorts to partial coverage prostheses such as Maryland Bridge, resin-bonded restorations, or removable prostheses in cases of multiple missing teeth. None of these treatment methods are completely satisfactory and have their drawbacks. Partial dentures are dependent on the child's compliance. They increase the rate of decay and may cause gingival disease leading to bone resorption. Furthermore, there is a need to refabricate a new prosthesis from time to time to compensate for craniofacial growth. Mini-screw implant placement in a young child would be an ideal method of treatment for the absence of teeth. They restore the function, preserve the alveolar bone, and give excellent esthetics, restoring the child's confidence and social acceptability. Parents are usually keen to get this treatment done as soon as offer the suggestion. To our knowledge, there is no previous study that compared the two techniques. The limited evidence shows that mini-screw implants supported pontics are useful transitional restorations for missing permanent maxillary incisors in children and adolescents; however, further well-designed clinical trials are needed in this regard. As a result, this study will be conducted to fill the gap of knowledge.
Clinical and Radiographic Evaluation of the Effect of Hyaluronic Acid Surface Treatment Versus Sandblasted Acid Etched on Stability of Delayed Dental Implant in Posterior Maxilla.
Commercially pure (CP) titanium is the gold standard to produce dental implants because it has a huge volume of scientific publications over a period of more than 50 years, it is cheap and simple to produce (i.e., making dental implants economically "affordable") and comes in numerous specitic designs of screws tor various indications. That is why more than 95% of the implant market 5 dominated by titanlum. However, there is an innovation trend to manufacture implants from more inert and biocompatible materials. Ceramic implants represent a valuable alternative for expanding the patient base of clinicians, especially in cases with challenging aesthetic demand. Furthermore, there has been a significant increase in the number of patients requesting metal-free dentistry or bio-holistic implant treatments. In the past, ceramics were often branded as "inferior" quality due to its reputation as being brittle but the growing volume of scientific publications specifically an zirconia are demonstrating that lt is comparable in fracture-strength with titanium implants. There is a clear market niche for zirconia implants, especially in cases of: - Aesthetic reconstructions in the anterior region, especially in patients with a thin gingival biotype - Gingival recessions where a white colored implant is a great advantage - For patients with a titanium intolerance/sensitivity - For patients who prefer a bio-holistic/metal-free dental approach. Today, clinicians are asking tor long-term clinical results of zirconia as a dental implant material. Therefore, Z-Systems AG is conducting this zirconia dental implant registry. A registry design was chosen because it will capture long-term benefits/risks from clinical routine without patient selection.
A within-subject cross-over study is done on eight completely edentulous patients to compare two different complete removable dentures. Group I: Heat cured Conventional complete dentures designed based on the neutral zone concept; Group II: CAD-CAM neutral zone complete dentures designed based on the neutral zone concept. Occlusal analysis is done by the T-Scan device, and evaluation of muscle activity is conducted by electromyography at insertion time, two weeks after insertion time, and one month after insertion time.
This randomized controlled trial is to clinically assess and compare impression quality of polyvinylsiloxane impression material using one step (experimental) and two step (control) impression techniques and its effect on marginal fit of prosthesis and proximal contact of prosthesis.
First, Participants in this study will be recruit according to inclusion criteria. Proper examination for the participants (clinically and radiographically). Preparation for abutment tooth for Resin bonded fixed partial denture. Checking and verification for the restoration (trying). Clinical assessment and survival evaluation of the final restoration on delivery and on follow-up every 12 weeks for 12 months.
- Background Adaptation of a dental implant and its restoration to the existing anatomy in the region of a missing tooth is presumed to be a reliable procedure. During the follow-up it appears that peri-implant bone level is stable, peri-implant soft tissues are healthy and patients are satisfied with the result. However, the number of 10-years studies on implants in the posterior region of maxilla and mandible is limited and much more studies with longer follow-up periods are needed to confirm the positive outcomes. - Main research question The primary objective of the study is marginal bone level changes by radiological assessments at 10-years follow-up. Secondary objectives are implant and restoration survival, condition of peri- implant mucosa and patients' satisfaction. - Design The study design is an observational study of a group of patients which were treated 10 years ago with a dental implant and an implant-supported restoration because of a missing tooth in the posterior region. Outcomes: primary outcome is the change in marginal peri-implant bone level 10 years after placing the definitive restoration. Secondary outcome measures will be implant and restoration survival, peri-implant mucosa health and patients' satisfaction using a questionnaire. - Expected results Stable peri-implant bone levels, stable peri-implant soft tissue levels, high implant and restoration survival rate and satisfied patients.
