Filter by:With a demographically ageing population and increasing patients with missing teeth, the demands on the healthcare system are set to further increase. This project is to prepare the public dental healthcare system to remain sustainable in terms of efficiency of denture production and healthcare manpower (lab technicians, clinician and operation staff). It aims to understand and improve denture fabrication productivity, enhance the treatment efficiency. This new model of care is a change from the current staged treatment process to batch processing assisted by new manufacturing methods, with the goal of improving sustainability and effectiveness of existing clinical and dental lab capacities.
The all-on-4 treatment approach for completely edentulous mandible is a proven concept. However, there are still issues regarding the use of metal substructure to support the prostheses such as allergy, metallic taste, and aesthetic. Therefore, other materials such as polyetheretherketone (PEEK) are being tested for its suitability and is showing good potential. However, available evidence is limited regarding its clinical performance. Thus, the aim of this study is to compare clinical performance of all-on-4 treatment concept utilizing PEEK versus conventional metal framework as substructure in fully edentulous mandible. Thirty suitable patients will receive either PEEK or conventional all-on-4 prostheses for fully edentulous mandible. The prostheses will be retained by four implants utilizing the all-on-4 principle. Clinical performance will be assessed during the follow up period of up 3 years concerning screw loosening, material chipping or fracture, wear or staining, prosthesis survival and success, implant survival and success.
The aim of the current study protocol is to compare the effect of two complete dentures made for completely edentulous patients; one digitally constructed using digital smile design (DSD) and another one conventionally constructed on the patient's quality of life and patient's satisfaction. It is a clinical trial in which two dentures will be made for each patient, one will be digitally constructed using digital smile design (DSD) and the other one using the conventional method with a washout period of 3 weeks. Each patient will receive a questionnaire "Oral Health Impact Profile -19" (OHIP -19) for the edentulous patients to evaluate his satisfaction with the denture.
The goal of this clinical trial study is to evaluate the accuracy of the full digital workflow for four-implant, screw-retained mandibular hybrid prostheses in patients with completely edentulous mandible.
The use of complete removable dental prostheses (CRDP) is a reliable and effective treatment option for the rehabilitation of edentulous persons. In recent years, the use of computer-aided design/computer-aided manufacturing (CAD/CAM) methods has become more popular for the fabrication of CRDPs, including subtractive methods (milling) from a prefabricated resin puck. They present various advantages compared to conventional fabrication methods, namely improved mechanical properties, superior surface characteristics, shortened manufacturing time and lower cost for the patient. However, one of the shortcomings in the manufacturing of CRDPs from a single block of resin is obtaining an adequate esthetic outcome, as the transition between the gingiva-colored (pink) and tooth-colored (white) resin is not as precise as with prefabricated prosthetic teeth which are incorporated into a denture base. A novel technology has recently been launched on the market and includes a new design of distribution of pink and white resin inside a prefabricated resin puck, which would allow a superior esthetic outcome than previous techniques. The aim of this pilot study is to assess the end result of one of the available systems used for fabricating digital dentures (Ivoclar® Digital Denture®), while using the corresponding monolithic resin puck (Ivoclar® Ivotion Denture System®), and therefore determining whether this new technique is an adequate option for treating edentulous patients.
Comparison between fixed and removable implant-retained complete prostheses previously showed that while patients appreciate the ergonomic cleaning of removable prostheses, they prefer the comfort and masticatory efficiency of fixed prostheses. New treatment strategies are emerging; the use of telescopic attachments now offers a prosthetic alternative for the treatment of edentulous teeth at a lower financial cost than fixed prostheses. To answer this question, the study is constructed as a cross-over. 30 patients will use a removable telescopic prosthesis and then a fixed prosthesis, or vice versa, for a period of 6 months according to randomization. They will answer a quality of life questionnaire after each period and finally choose their favorite prosthesis. The null hypothesis is that removable telescopic implant prostheses will result in a quality of life comparable to that obtained with fixed implant-supported prostheses. The primary objective of this study is to demonstrate the non-inferiority of removable versus fixed prostheses on quality of life after 6 months of use of each implant-supported prosthesis in edentulous maxillary or mandibular patients. The measurement of the evolution of the quality of life is analyzed using the GOHAI questionnaire after 6 months of use of each prosthesis. The secondary objectives are to: - Determine the decisional parameters in the final choice of the prosthesis by the patient at the end of the study, with the Mc Gill Denture Satisfaction Instrument, - Compare the masticatory efficiency between the two dentures (duration, number of cycles and frequency of chewing of the carrot test food, with each denture after 6 months of use), - Compare the oral hygiene between the two prostheses (peri-implant plaque index, after 6 months for each prosthesis), - Compare the adjustments and repair required after the placement of each prosthesis and the chairside treatment time to achieve them, - Compare the complications and their frequency of occurrence with each type of prosthesis during the 6-month wearing period.
Will the use of locator attachment influence the muscle efficacy when compared to ball and socket attachment in mandibular implant overdenture? '
The better form of ridge will provide using wider implants that can have better abilities to with stand forces and to prevent alveolar bone loss as much as possible. Ridge expansion gained some popularity due to easiness compared to any other procedure that can gain bone. However, this treatment modality needs to be evaluated as compared to Mini Dental Implants (MDIs) over denture in thin mandibular ridge. In mandibular edentulous patients having thin ridge, does the mini implant supported over denture, compared to the conventional implant supported over denture after bone expansion affect bone height around implants?
