Filter by:When the tooth is severely compromised, it needs a prosthetic crown. The tooth is prepared to allow the housing of the prosthetic crown without difficulty. This study aims to compare two different types of preparations to see with which of the two the gingival tissue reacts best.
investigating the effect of glazing and polishing on the color difference between natural teeth and all ceramic crowns made from celtra press (zirconia reinforced lithium silicate ceramic).
evaluation of color difference between zirconia reinforced lithium silicate (celtra press) VS lithium disilicate (Emax) in relation to natural tooth structure to determine which monolithic material will provide restoration with exact shade and optical properties as natural tooth structure.
Dentistry is a rapidly progressing field with innumerable advances taking place on a day to day basis. The application of newer technologies and materials has advanced the specialty of prosthodontics and the services rendered to the patients. Taking into consideration that PEEK as a material wasn't clinically investigated to be used as a material for routine use, however PEEK in removable partial dentures will help in making many steps easier and reach patients demands regarding esthetics. Also, owing to the superior mechanical and biological properties of PEEK, it will not be surprising if dentures constructed from the polymer are routinely constructed in near future.
- Steps in short: Undergoing the conventional steps of maxillary single denture construction till the step of framework construction that will be designed and constructed using CAD/CAM after optical scanning of the master cast ( 2 frameworks to cover the palate and crest of the ridge : one made of titanium and the other made of cobalt/chromium) then conventional steps will be undergone including bite, Try-in and delivery ending by measuring the denture retention. - Number of visits & follow up period : Visits: will be 5-6 visits for each patient. Follow up period: 6.5 months (immediately post-insertion then after 1 week then after 3 months for the first type then 2 weeks washout period and the same for the second type)
On of the main fixed prosthetic options of completely edentulous patients is the screw-retained implant supported prosthesis which was constructed on transmucosal abutments with its encountered problems such as: hardness to make it passively seated with multiple screw fracture and loosening problems and multiple encountered veneer material fracture and so there effect on patient satisfaction with multiple maintenance recalls.so, the investigators want to try a new technique of fabrication which was proposed for reducing the problems of lack of passivity which is the intraoral luting cement technique on titanium bases with reduced screw number but, with luting cement problems as de-cementation and cement biological effects on soft tissues and bone and there effect on number of patient recall visits and maintenance and so there effect on patient satisfaction
the trial is done in order to reinforce polyamide to improve its modulus of elasticity to be able to use it as a denture base material in all clinical cases
PICOTS: P: Kennedy class І patients I : Mandibular removable partial denture with OT Cap attachment C: Mandibular removable partial denture with gingival approaching clasp assembly O: 1ry outcome: Oral Health Related Quality of Life 2ry outcome: Biting force T: 1 Year S : Randomized control trial Research question: In Kennedy class І patients will the removable partial denture with OT Cap attachment compared to conventional removable partial denture with clasp assembly results in difference in Oral Health Related Quality of Life of Patients?
