Abstract: This study was designed to evaluate mesenchymal stem cell (MSC)‐based alveolar bone regeneration in a canine saddle defect model. MSCs were loaded onto hydroxyapatite/tricalcium phosphate (HA/TCP) matrices. Scanning electron microscopic (SEM) evaluation demonstrated greater than 75% MSC coverage of the HA/TCP porous surface prior placement regardless donor. Matrices, 6 mm×6 mm×20 mm, with and without cells, implanted for 4 9 weeks, then removed histological formation. Cell‐free...

Abstract Purpose Removable partial dentures ( RPD s) represent standard treatment for edentulism despite major shortcomings. To alleviate these shortcomings, endosseous implants provide support and stability as well contribute to maintenance of alveolar bone. This prospective, within subject, time series study evaluated patient‐based outcomes s compared implant‐supported removable ISRPD s). The hypothesis was that the would substantially improve oral health quality life patients. Materials...

This study compared the acceptability and relative effectiveness of case‐based learning (CBL) versus traditional lecture‐based (LB) instruction in a preclinical removable prosthodontics course University North Carolina at Chapel Hill School Dentistry DDS curriculum. The entire second‐year class (N=82) comprised this crossover study's sample. Assessments baseline comprehension confidence partial denture (RPD) treatment planning were conducted beginning course. Near end course, half received...

Abstract Purpose The purpose of this retrospective, cross‐sectional study is to evaluate if there a difference in number visits (including fabrication and postoperative) remake rate when comparing conventionally fabricated digitally complete dentures by dental students predoctoral student clinic. Materials methods This two‐year retrospective consisted chart review for patients receiving maxillary and/or mandibular between 2017 2019 (n = 314) at the UNC Adams School Dentistry No control group...

Abstract Adult mesenchymal stem cells (MSCs) are used in contemporary strategies for tissue engineering. The MSC is able to form bone following implantation as undifferentiated adherent hydroxyapatite (HA)/tricalcium phosphate (TCP) scaffolds. Previous investigators have demonstrated that human MSCs (hMSCs) can be differentiated osteoblasts vitro by the inclusion of vitamin D and ascorbic acid. aim this study was compare osteogenic potential predifferentiated marrow–derived, culture-expanded...

Purpose : The purpose of this project was to compare alveolar bone repair by allogeneic mesenchymal stem cells using bioglass or synthetic hydroxyapatite (HA)/tricalcium phosphate (TCP) granular scaffolds delivered in a thermoplastic polymeric carrier. Materials and Methods Canine were obtained from iliac crest marrow beagle dogs expanded without differentiation. Cells resuspended at final concentration 5 × 10 6 cells/ml carrier (30% w/v Pluronic F‐127) mixed with an equal volume HA/TCP...

To determine whether a collagen scaffold could provide an environment for mesenchymal stem cell (MSC)-related bone repair of critical-size defects in rat calvaria.Craniotomy were created 28 adult Sprague-Dawley rats. Two additional rats used as MSC donors by means femoral marrow lavage and culture. The randomly divided into four groups: (1) empty/no graft; (2) (matrix)+saline; (3) matrix+MSCs; (4) matrix+bone morphogenetic protein. animals euthanized days after surgery. Microcomputed...

The purpose of this study is to assess students' perception digital waxing software for dental anatomy education. Dental students were introduced during a course, and requested finish voluntary survey. Students strongly agreed (18.2%) or (48.0%) with the statement "digital contributed my learning anatomy", (29.9%) (55.8%) "The helped develop wax-up skills". may be effective education, but do not believe can replacement conventional practice.

Aim: The purpose of this study was to digitally quantify the consistency and variation printed resin crown patterns produced by different 3D printers, aiming evaluate their clinical relevance accuracy. This accomplished evaluating manufactured using three printers materials, assessing fit adaptation through digital scanning analysis. objective determine internal marginal variations identify printer material combinations that produce most consistent clinically acceptable results. Methods: A...

Palateless overdentures (PLODs) provide advantages of improved taste perception and retention over conventional dentures. We aimed to evaluate 5-year outcomes four implant maxillary PLODs.
