Filter by:Complete dentures represent the traditional dental treatment for patients without teeth. However, retention and stability of this type of denture are often lacking, so dental implants are indicated in order to improve the stability of the denture, along with the satisfaction of the patient. Usually, the dental implants are inserted and then a period of 3-6 months is waited before any denture is connected to them. Recent studies have demonstrated that connecting the lower denture to the implants immediately after the implant placement, leads to an improvement in the result, with a social and psychological benefit for the patient. Therefore, the aim of this research project is to evaluate the application of the immediate connections of the implants for the upper dentures. 15-40 patients wearing an upper denture will receive 4 dental implants and the denture will be immediately connected. To simplify the surgical procedure, the implants will be placed without exposing the bone. This surgical technique is called guided surgery. Secondary objective of this research project will be the evaluation of the precision of the implant positioning, using this specific technique. The patients will be followed up for 12 months, for the implant and denture evaluation, as well as the evaluation of patient satisfaction and impact on quality of life through questionnaires.
The study is a within-subject randomized clinical trial that will compare and evaluate patients' satisfaction and digitally analyze denture space Confines. Group I: CAD/CAM. (computer-aided design/computer-aided manufacturing) Conventional complete dentures will be designed based on the bone support concept, Group II: CAD/CAM neutral zone complete dentures will be designed based on the neutral zone concept. The participants will be selected according to inclusion and exclusion criteria and will be randomly allocated into both groups and then shuffled to the other group using the Research Randomizer Program.
The study is a crossover, randomised, controlled clinical trial that will compare and evaluate patients' satisfaction and oral microbiota proliferation in two groups. Group I: Conventionally manufactured CRD Group II: 3D-printed (three-dimensionally printed) CAD/CAM (computer-aided design/computer-aided manufacturing) manufactured CRD, The participants will be selected according to inclusion and exclusion criteria and will be randomly allocated into both groups and then shuffled to the other group using the Research Randomizer Program.
A crossover clinical trial investigates two novel CAD/CAM techniques for complete removable dental prostheses for edentulous patients, milling and rapid prototyping (3D-printing) in a clinical setting of an undergraduate student clinic. Outcome parameters concern the dentures' trueness, retention, stability, esthetics and occlusion. Secondary outcome parameters include willingness to pay and prosthetic maintenance need.
Polymethyl methacrylate have been used since 1937 as a gold standard for a denture base material because of its several advantages as; good esthetics, adequate strength, easy repair and simple processing techniques. As any material it has some problems as polymerization shrinkage, low impact and flexural properties and low fatigue resistance2. So polyamide was introduced into dentistry to be used as a denture base material in order to solve these problems. Polyamide denture base materials have some superior properties than PMMA as; High impact & flexural strength, excellent esthetics and less release of residual monomers4. Although being an advantage from the point of patient satisfaction, flexural property considered to be a contraindication for a denture base material. The invistigators' trial is done in order to improve rigidity of a polyamide material as well as to improve oral health related quality of life in comparison to heat cured polymethyl methacrylate.
