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
The goal of this cohort observational study is to compare in the survival rate of ceramic dental implants placed in patients with missing or hopeless teeth . The main question[s] it aims to answer are: - Are there any significant differences in survival rate between the use of one-piece ceramic implant versus the two-piece (TL) variant? - What are the complications associated to the procedure and differences between the two groups.
The goal of this prospective case series is to compare the adjunctive use of enamel matrix derivatives in the treatment of tooth autotransplantation in terms of clinical attachment level. The main question it aims to answer is: - What is the benefit, in terms of clinical attachment level, of using enamel matrix derivatives adjunctive to tooth autotransplantation? Participants will be subjected to a digitally protocol of tooth autotransplantation.Only one group (test) is assessed. It will be supplemented with the application of enamel matrix derivatives before the placement of the transplanted tooth into the surgically produced alveolus.
This cross-sectional study aims to perform a population-based assessment of the incidence of decay, dental fillings, root canal fillings, endodontic lesions, implants, implant and dental abutment crowns, pontic crowns, and missing teeth, taking into account the location.
As part of the clinical study, 25 patients each were provided with removable partial dentures with clasps made of PEEK in two centres (University Hospital Heidelberg, Department of Prosthodontics and University Hospital for Dental Prosthetics Innsbruck). The patients were examined over a period of 3 years for the number and type of technical or biological complications and questioned about their oral health-related quality of life.
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.
Space maintainers are frequently used to prevent malocclusion problems in early primary tooth loss. Oral health literacy is defined as the capacity of individuals to learn, understand and evaluate basic oral health information. It is considered that parents' awareness of space maintainers may be affected by various factors such as their demographic characteristics and oral health literacy. The aim was to evaluate the relationship between variables by determining parents' awareness of space maintainers and their oral health literacy.
About 40 people will participate in the study, which will be conducted at Southern Medical University Southern Hospital. All subjects need to sign an informed consent form before screening, and successful subjects can enter the study. Experimental and control subjects were treated according to the protocol. Treatment was held until the participant entered a follow-up period, or until any of the withdrawal criteria were met. According to conventional clinical practice, the study needs to evaluate the patient's subjective perception and soft and hard tissue changes at 3 months, 6 months, and 1 year after successful implant placement. The specific process is divided into: 1. Screening period: All subjects need to complete the relevant examinations of the screening period before enrollment, and screen according to the admission criteria. (1) Sign informed consent; (2) Record demographic data: date of birth, gender, initials; (3) Medical history and physical examination: collection includes understanding of any current or past diseases, medications, drug allergy history, surgical history, radiotherapy and chemotherapy history, ethnic background, smoking history, whether alcoholism, oral hygiene habits and oral examination, etc.; (4) Among them, oral examination includes the whole oral health before and after surgery and oral and maxillofacial CBCT imaging examination; 2. Treatment period: the control group underwent transalveolar crest parietal maxillary sinus floor lift immediately after implants; The experimental group underwent implant implantation after 6 months of transalveolar crest parietal maxillary sinus floor lift. 3. Follow-up period: The study needs to evaluate the subjective feelings and soft and hard tissue changes of patients at 3 months, 6 months and 1 year after implant placement.
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.
