Description:
Biomaterials and their physiological interactions. Materials used in medicine/dentistry: metals, ceramics, polymers, composites, resorbable, smart, natural materials. Material response/degradation: mechanical breakdown, corrosion, dissolution, leaching, chemical degradation, wear. Host responses: foreign body reactions, inflammation, wound healing, carcinogenicity, immunogenicity, cytotoxicity, infection, local/systemic effects.
Course Topics:
1) Design parameters applicable to biomaterials
2) Reconstructive materials used in medicine and dentistry (metals, ceramics, polymers, and composites)
3) Regenerative materials used in medicine and dentistry (bioresorbable materials, films/coatings, smart materials, natural materials, biologically functional materials)
4) Material response - material degradation in-vivo (deformation/mechanical breakdown, corrosion, dissolution/leaching, chemical degradation, friction/wear)
5) Host responses (foreign body reactions, inflammation, histological/hematological considerations, wound healing, carcinogenicity, immunogenicity, cytotoxicity, infection, local and systemic effects)
6) Methods of testing material performance (in-vitro and in-vivo methods and models, standardization and retrieval analysis)
7) Design principles for individual applications (biocompatibility, mechanical properties, cell adhesion properties, protein adhesion properties)
Course Objectives:
1) To teach students the interdisciplinary issues involved in biomaterials design, synthesis, evaluation and analysis, so that they may pursue higher-level, more focused to graduate courses in biomaterials, address research problems, or pursue a job-search in the medical device industry
2) To teach students the basic classes of reconstructive biomaterials and how these materials differ from similar classes of materials used in other industries
3) To teach students the basic classes of regenerative biomaterials and how combinations of materials and biological moieties may be used in combination to orchestrate a desired physiological response
4) To teach students mechanisms of material degradation in-vivo and how to apply these concepts to biomaterials design and analysis
5) To teach students mechanisms of host responses to biomaterials so that these concepts may be used to design and evaluate new and existing biomaterials
6) To provide students with a greater familiarity with the biomaterials research literature 7) To provide some training in critical thinking and analysis
8) To provide some training in (written and oral) communication of scientific and engineering ideas
Course Outcomes:
1) Given a clinical problem involving lost tissue structure and function, students should be able to express a range of potential biomaterial treatments options, including synthetic and/or biological strategies.
2) Given a biomaterial design problem, students should be able to outline all parameters needed to optimize the design.
3) Given a specific biomaterial, students should be able to identify the advantages and disadvantages of this material in terms of its material degradation and host response.
4) Given a specific organ/tissue system in need of reconstruction or regeneration, students should be able to identify appropriate candidate materials and an appropriate time frame of service-life.
5) Given a specific biomaterial, students should be able to identify the important biological responses of potential importance.
Assessment Tools:
1) Biweekly, problem sets to test objectives 1) - 5) for individual students (50/450 points)
2) In class three closed-book exams to test objectives 1) - 5) for individual students – focus on design principles of biomaterials and related biological events (150/450 points)
3) In class 10-minutes presentation on a freely chosen paper related course topics to test objectives 1) – 5) and help students to develop critical journal reading ability (50-/450)
4) A written proposal and an in-class presentation of a research idea on biomaterial development to test assignment to test objectives 1-5 for groups of students - define a problem in biomaterials, pose research questions/hypotheses and methodologies to address this problem, and write a research proposal to address this question (150/450)
5) In class participation to encourage interactive discussions (50/450).
