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.
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).
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.
