Filter by: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.
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.
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.
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.
Maintaining the general health and well-being of patients is the main goal of dental therapy. However, tooth extraction is indicated when teeth cannot be maintained in a status compatible with health, adequate esthetics, function, and/or for strategic reasons. A variable degree of alveolar ridge atrophy related to bone resorption is initiated immediately after removal of a tooth due to the local physiologic remodeling and the inflammatory response. Ridge resorption is more accentuated in the horizontal dimension, followed by the vertical mid-facial and vertical mid-lingual in non-molar and molar teeth. Among local periodontal phenotypic characteristics, facial bone thickness at the time of tooth extraction seems to be strongly associated with the extent of alveolar bone resorption. Dental implants have increased in popularity due to their unique ability to replace teeth. During the planning phase of implant therapy, one of the main parameters assessed is the amount of residual alveolar ridge. Therefore, when tooth replacement therapy via dental implant is considered, adequate management of the site is critical to predictably preserve or reconstruct the architecture of the alveolar ridge, particularly in the anterior aesthetic zone, where its structure play a crucial role in the maintenance of function, health and esthetics. Generally, with appropriate treatment planning and execution, the adequate primary mechanical stability of the dental implant is achieved. However, bone and/or soft tissue augmentation procedures could be needed for the adequate management of deficient edentulous ridges at the time of implant placement, and these types of treatments could considerably increase the risk of morbidity, treatment expenses, and length of treatment time. Nevertheless, Implant placement with additional bone contour augmentation therapies have shown their effectiveness in the short-, mid- and long-term in contemporary dental practice. However, to the present date, there is no information available in the literature regarding patient-reported outcome measures in patients that received tooth replacement therapy via dental implants with additional contour bone augmentation in the short-, mid- and long-term.
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.
The aim of the study is to prospectively evaluate the survival of JJGC Cobalt-Chromium (CoCr) prosthetic abutments in single-unit implant-supported prostheses, to confirm the long-term safety and performance of the devices.
Hybrid Funnel Technique arises from the union of subtractive and non-subtractive techniques for implant site preparation. Hybrid funnel technique is performed with specially designed drills and osteotome. the aim of the study is to examine marginal bone level and implant stability of implants inserted with two different techniques for the surgical implant site preparation.
