Filter by:Isolated sinus pneumatization after single tooth extraction indicate sinus lifting for proper implant placement. The conventional way of using osteotomes to elevate the sinus is annoying to patient and also does not give the needed amount of bone around the implant. Introducing new intervention of Densah Burs helps increase bone gain around implant and decrease the patient discomfort.
The principal aim of the study is to evaluate the prosthetic complications with CAD-CAM fabricated provisional prostheses and denture conversion prostheses after 3 months of function. Supported restorations are now a predictable treatment modality for the rehabilitation of complete and partially edentulous jaws.Immediate loading of the placed implants is performed for the rehabilitation of the edentulous arch to improve patients' function. This can be usually done by converting the existing denture base of the patient or by making a CAD- CAM milled provisional prosthesis integrating digital workflow. A laboratory fabricated denture base can be converted into a screw-retained provisional prosthesis post implant placement. This is known as conversion prosthesis. However, drawbacks of these prostheses include increased chairside time for the clinician leading to inconvenience for the patient and a potential for an error in prosthesis fabrication. With the introduction of CAD-CAM technology, it is now possible to fabricate a provisional restoration using digital workflows. This workflow would help the clinicians save a considerable amount of chairside time and obtain potentially stronger restorations better polished and without contamination of surgical field. Studies assessing the soft tissue response and patient-reported outcome measures between denture conversion and CAD- CAM fabricated provisionals are currently lacking in the literature.
This study will be initiated to compare the accuracy of implant placement using the guided trephination drilling protocol and the guided conventional drilling protocol.
The purpose of the study is to compare soft tissue volume changes in terms of volume gain and stability around dental implants and PROMS in cases where a sub-epithelial connective tissue graft (SCTG) from the palate, Porcine collagen matrix (CM) or Porcine Acellular dermal matrix (PADM) is used after 3 and 15 months after implant placement.
The study will compare between osteotome technique and New Reverse Drilling Technique in the placement of dental implant in posterior maxilla , primary outcome will be Implant stability that will be measured by Periotest device . follow up for 6 month. secondary outcomes will be crestal bone loss , pain and swelling.
- Patients were randomly divided in to two groups by using computerized software ; the first group received flat magnetic attachment design while the second group received dome magnetic attachment design.which the inclusion criteria is completely edentulous patient ,Age range from 40 to 70 year old ,skeletal class 1, both sexes - Implant stability will be measured for both groups using smart peg /osstell at the day of implant installation and after 2,4,8,12 weeks. - Patient satisfaction measure in 2 weak and after 12 weak by Denture satisfaction questionnaire
CAD/CAM (computer aided design/ computer aided manufacturing) constructed screw retained implant supported frameworks give solutions for the problems arising from the lost wax technique by improving accuracy, adaptation and passive fit of the final restoration. However, concerns about the passive fit of a pre-implant insertion CAD/CAM constructed framework still exists due to the expected errors in imaging, registration, surgical guide construction, adaptation and hence transferring the planned position intra-orally.
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.
