NCT07448701
This prospective clinical study compares two cementation techniques for implant-supported zirconia fixed partial dentures on titanium bases (Ti-bases): extraoral cementation performed on the working model and intraoral cementation performed chairside. Thirty clinical cases with two osseointegrated implants requiring a multi-unit zirconia restoration will be recruited at the UIC Dental Clinic. For each case, two restorations with identical design will be produced: one will be cemented extraorally (control) and an identical replica will be cemented intraorally (test). Micro-deformation will be assessed as peri-implant microstrain (µε) using a standardized strain-gauge setup and the same recording protocol for both techniques. The primary analysis compares microstrain between intraoral and extraoral cementation within each case; implant/prosthetic events will be recorded descriptively.
NCT07315607
This clinical trial aims to evaluate the in vivo accuracy of a fully digital workflow for the immediate placement of a previously fabricated screw-retained provisional crown using digital planning and guided implant surgery. The study will be conducted in partially edentulous adult patients requiring the replacement of a single tooth with an immediately loaded dental implant. The main objective of the study is to assess the accuracy (trueness and precision) of the planned digital implant position and provisional restoration by comparing the virtually planned position with the actual clinical outcome after guided surgery. Emphasis will be placed on linear, angular, and rotational deviations at both the implant and provisional restoration levels. Participants will undergo a fully guided implant placement procedure with rotational control, followed by the immediate placement of a prefabricated screw-retained provisional crown designed during the digital planning phase. Postoperative intraoral scans will be obtained to register the final implant and restoration positions. The planned and achieved positions will be compared using three-dimensional analysis software to quantify deviations and determine whether the accuracy achieved remains within clinically acceptable limits.
NCT06666595
Objective: To report the implant survival rates, clinical, and radiographic outcomes of subcrestal short implant versus crestal standard length implant supported removable partial denture (RPD).
NCT06567262
Patients will be randomised to receive CAD/CAM metallic removable partial denture (RPD) followed by Conventional metallic RPD (Group A), or the opposite sequence (Group B), with a 3-month wear duration for each denture and washout period for one week. Patients will be recalled at base line and 3 months following prosthetic insertion to evaluate Oral health related quality of life. It is hypothesized that removable partial dentures with CAD/CAM metallic RPD frameworks would improve Oral health related quality of life than those with Conventional metallic RPD frameworks.
NCT00725049
This prospective randomized study will evaluate the integration success while supporting a prosthesis for short implants placed into maxillary sites having minimal bone height that would otherwise need sinus augmentation. The resources utilized during treatment will be assessed. Study (null) hypothesis: the overall benefit of using short length implants to avoid sinus augmentation procedures will offset differences in the cumulative implant survival rates observed between treatment groups.
NCT03769376
The purpose of this study is to compare the speed of bone healing of the two most commonly used xenografts on the market, Bio-Oss® and Salvin-Oss® using a tooth extraction ridge preservation model in participants scheduled for tooth extraction and subsequent receipt of a dental implant. Researchers hypothesize that there will be additional vital bone at 16-20 weeks with Salvin-Oss®.
NCT03471000
The aim of the study was to determine whether implant length and the crown-to-implant (C/I) ratio influence implant stability and the loss of the surrounding marginal bone, and whether short implants can be used instead of sinus augmentation procedures.
NCT03934853
A confirmatory dual-clinic, non-randomized study of the Inliant device to aid in dental implant placement in humans. The hypothesis is that using the Inliant Surgical Navigation System ("Inliant") will provide a high degree of accuracy in multiple dimensions relative to the ideal implant position as determined in the planning stage, and will not result in any adverse outcomes related to use of the device. Five clinicians (Investigators) of various clinical backgrounds and experience will use the Inliant device, a licensed, medical device in Canada, to place a dental implant in a total of twenty (20) subjects.
NCT01324778
To compare marginal bone level alterations, implant stability and implant survival between OsseoSpeed och OsseoSpeed TX
NCT02701387
The purpose of this study is to determine whether implant thread design impacts bone remodeling and/or dental implant stability in the early healing period. The population of this study will consist of a group of subjects who are interested in replacing two or more missing teeth with dental implants. All implant sites will be healed and not require bone augmentation for the placement of a standard 4 mm diameter implant. Subjects first will undergo a brief screening exam. If accepted, comprehensive oral exam will be completed. Subsequently, enrolled subjects will be scheduled for dental surgery to place the implant(s). Subjects will return weekly for the first 8 weeks after placement for a brief post-operative appointment in order to conduct measurements for the study.
NCT02180230
The aim of this study was to evaluate the 7 mm long implants NobelSpeedy Shorty and Brånemark System Mk III Shorty: by determining the marginal bone remodeling, implant survival rate, soft tissue health and maintenance.
