Filter by:complete denture wearers struggle to eat well with their dentures due to poor denture retention, stability, and occlusal disharmony. So, the current study protocol aims to compare the occlusion/ disocclusion time in immediately loaded implant retained overdentures supported by two interforaminal implants; splinted versus non splinted dental implants compared to the conventional complete denture.
Forty patients ( 24female and16 male )with completely edentulous maxilla and mandible . All patients received implant supported mandibular and maxillary overdentures. The patients were randomly divided into two groups according to attachments retaining Max IOD that supported by four axial implants in maxilla . The TA was used to retain group I (GrI) MaxIOD , while that of group II (Gr II) was retained by LA. MaxIOD retention and MBL(vertical and horizontal) around implants of both groups was recorded at time of insertion (R0) ,then twelve(R12)and (R24) months following insertion of the prosthesis.
To compare the accuracy of digital impression and conventional impression for complete-arch implant-supported fixed prosthesis
The goal of this split-mouth randomized clinical trial study was to investigate the effect of using a laser on pain and discomfort following flapless dental implant surgery. It was hypothesized that laser did not have any impact on post-op pain. Therefore, the study aimed to compare pain and discomfort following flapless dental implant surgeries with or without a laser.
To evaluate the clinical and radiographic outcomes of KS implants used to rehabilitate edentulous mandible with dental-retained overdentures, and to compare it with same treatment on TS implants
The aim of the present study was to evaluate open faced maxillary complete denture with soft acryl resin wing versus conventional heat cured maxillary complete denture regarding the retention and patient satisfaction.
CAD/CAM-fabricated PEEK bar exhibited greater dimensional deviation in comparison to its titanium counterpart. Nevertheless, patients with PEEK bars reported higher satisfaction levels and lower marginal bone loss when compared to those with titanium bars.
This pilot study aims to compare the difference, if present in patient satisfaction, denture base adaptation and retention in 3d printed maxillary complete dentures fabricated at a build angle of 0 degrees versus 45 degrees.
This clinical trial aims to observe if there are differences in bacterial micro-filtration on interfaces and to evaluate if there are differences in the occurrence of peri-implant diseases and bone loss in fixed partial monolithic zirconia CAD/CAM implantsupported prostheses with and without abutment in patients at the Advanced Implant Prosthetics Clinic of the Complutense University of Madrid, of both sexes, over 18 years of age, whose treatment plan is based on the replacement of dental pieces with two fixed partial dentures on implants, in such a way that the study will be performed "split mouth" rehabilitating one of them with zirconia bridges on attachments with connection and others with Zirconia bridges with flat attachments or without connection. The main question it aims to answer is whether the not use of abutment influence bacterial micro-leakage and the development of peri-implant diseases and bone loss at that level in fixed partial monolithic zirconia CAD/CAM prothesis. Participants will: - Receive two fixed partial monolithic zirconia CAD/CAM prothesis, one will be attached to an abutment (control group) and the other not (test group) - Subsequently, control appointments of the fixed implant supported prosthesis treatment will be performed (1, 3,6, 12 and 24 months) and radiographies will be made with the parallelizing device attached by the silicone key. Researchers will compare fixed partial monolithic zirconia CAD/CAM implant-supported prostheses with and without abutment to see: - Differences in bacterial micro-leakage on interfaces. - Occurrence of peri-implant diseases and bone loss
CAD/CAM (computer-aided design and computer-aided manufacturing) can be a game-changer for better access to care by edentulous patients. Digital overdentures offer potential for more satisfied patients due to better fit and can be provided faster/with lower costs. Providing digital overdentures has potential to enhance access to oral healthcare by the elderly, given the expected benefits (better quality, simpler, faster and more affordable than those obtained traditionally). However, evidence from randomized trials is crucial to verify the relevance of those benefits, especially from the patient perspective, and to confirm those benefits. This trial also serves as an opportunity to improve CAD software and materials, since it will identify technical challenges specific to the provision of digital overdentures. This randomized cross-over trial aims to reveal whether implant-retained mandibular overdentures (IMO) produced by CAD and 3D printing are more satisfactory to edentulous seniors than those fabricated using traditional methods. The investigators will recruit 26 edentulous participants (any sex/gender) amongst previous patients at McGill University, based on the following eligibility criteria: complete edentulism, elderly (age ≥60 years, according to the WHO), need for new maxillary and mandibular complete dentures, ability to complete questionnaires, and previous treatment with two implants in the anterior mandible. Each participant will receive two pairs of dentures, as per the McGill Consensus on Implant Overdentures (i.e., a mandibular overdenture opposed by a maxillary complete denture: (i) one by digital rendering of the mouth, virtual prosthetic design and 3D printing; (ii) a control pair, by traditional clinical and laboratory methods. Each pair will be worn for 3 months according to a random sequence (total follow-up: 6 months after the delivery of the first pair of dentures). Both overdentures will be retained by 2 Novaloc abutments and medium retention matrices. Outcomes will include patient satisfaction ratings and oral health-related quality of life. The investigators will evaluate other patient-reported outcomes, as well as clinician-assessed quality and cost. Outcome assessment will occur at baseline, then at three months after participants have worn each pair of dentures. Following the cross-over, participants will keep their preferred denture pair and return after 12 months to evaluate maintenance requirements, including stained and broken dentures.
