Filter by:This study is aimed to compare between titanium framework and soft metal framework used for mandibular All-on-4 implant supported prosthesis. The evaluation will be for: - Peri-implant soft tissue health including; Plaque index, Probing depth and bleeding index. - Bone level changes around implant using periapical x-ray after 6 months and 12 months and 18 months from insertion of fixed prosthesis. - Framework adaptation of titanium framework and soft metal framework using surface matching software. Patient grouping: • 20 Patients will be classified into 2 equal groups, first group will receive 4 implants placed according to All on 4 concept supporting screw retained prosthesis with titanium framework manufactured by dry milling technique, second group will receive 4 implants placed according to All on 4 concept supporting screw retained prosthesis with metal framework manufactured by dry milling/post sintering of Co-Cr soft metal blocks. The evaluation will be for: • Bone level changes around implant using periapical x-ray after 6 months and 12 months and 18 months from insertion of fixed prosthesis.
This study is a randomized clinical trial comparing the conventional method of recording occlusal vertical dimension using Willis gauge from the base of the nose to the base of the chin with the other method using vernier caliper for the length of the index finger to access the satisfaction level of edentulous patients acquiring complete dentures.
Post-Market Clinical Follow-Up to evaluate the safety and performance of IDI dental implant systems : confirmation of osseointegration of the different implants at the loading visit (between 2 and 6 months after surgery).
The aim of the present project is to evaluate functional, biological and technical variables, as well as quality of life and satisfaction as indicators of long-term clinical performance of single prostheses on short implants in the posterior region with a 10-year prospective follow-up. This proposal refers to a clinical research project with a 10-year follow-up of single crowns on short implants (6 mm) in the posterior region of the maxilla and mandible. The cohort has started in 2010 through a project funded by the International Team for Implantology. The main clinical results with a 4-year follow-up showed the influence of biomechanical factors (implant/crown ratio) on short-term treatment success and increased risk over time. The sample will consist of participants from the cohort of the research project established in 2010, who received a single crown on a short implant (6-mm Standard Plus Wide Neck SLA) in the posterior region of the maxilla or mandible according to eligibility criteria and standardized clinical procedures. Data will be collected by clinical and image exams, questionnaires (for sleep bruxism, satisfaction and quality of life), recording of maximum occlusal force, measurement of perimplant bone changes, and calculation of the clinical crown-implant ratio. Data will be analyzed by descriptive and inferential statistics with survival analysis and multivariable models, if assumptions are met, at the significance level of 0.05.
Tooth loss is common and as consequence deteriorate patient's health and quality-of-life. Dental prostheses aim to restore patients' appearance and functions by replacement of missing teeth. The occlusal morphology and 3D position of the healthy natural teeth should be adopted by the dental prostheses (biomimetic). Despite computer-assisted design (CAD) software are available for designing dental prostheses, considerable clinical time are still required to fit the dental prostheses into patients' occlusion (teeth-to-teeth relationship). Teeth of an individual subjects are genetically controlled and exposed to mostly identical oral environment, therefore the occlusal morphology and 3D position of teeth are inter-related. It is hypothesized that artificial intelligence (AI) can automated designing the single-tooth dental prostheses from the features of remaining dentition.
In recent years there is a rapid increase in the use of computer aided design and production. Two main types of materials are used in the production of indirect CAD/CAM restorations namely resin composite based and ceramic ones. Mechanical properties and esthetics of ceramic materials are superior to resin composites but the advantages of intraoral repair, easy adjustments and polish of resin materials are undeniable. Improvements of mechanical properties of resin-based materials resulted in the development of resin composite blocks. 3D printed restorations, which can be performed as chairside in one session can be manufactured in case of any broken / chipping / debonding cases, without the need for repeated impression making. This saves time for the patient and the clinician. By using these 3D resin-based composite materials in fixed partial dentures, intraoral repairs can be performed. In addition, the high costs of burs and possible damage to the CAD/CAM blocks used in ceramic milling are eliminated when restoration are manufactured in printers with the DLP technology. The objective of this study was to evaluate the clinical outcome of 3D printed posterior resin composite FDP restorations up to 3 years.
The purpose of the multi centre study is to evaluate an intervention, which means that patients undergoing radiotherapy for head and neck cancer will receive fixed dentures in accordance with the Public Health Care fee system with regard to well-being and oral health related quality of life. Hypotheses: the intervention will improve oral health related quality of life, general wellbeing, and nutrition in patients treated by radiotherapy, with or without combination of chemotherapy or surgery against head and neck cancer.
This study aims to compare how a single cap best fit on a tooth that is fabricated with digital and conventional impression techniques.
The objective of this study was to compare the 5-year survival and clinical behavior of single posterior ceramic crowns made with pressable ceramic on zirconia or on a metal framework. If failures occurred, the further aim of the study was to delineate the factors contributing to the failure. The null hypothesis stated that the survival of zirconia-based restorations would be no worse that those made with metal-based material.
