Abstract
This comprehensive review examines the integration of evidence-based practice (EBP) in prosthodontics across educational institutions and clinical settings. The article highlights how systematic incorporation of research evidence, clinical expertise, and patient values is revolutionizing prosthodontic education and treatment protocols. Through analysis of current educational frameworks, digital technology implementation, and documented clinical outcomes, we demonstrate that EBP adoption significantly improves treatment predictability, enhances student learning, and optimizes patient satisfaction. Case studies from leading dental institutions showcase successful implementation strategies, while identifying barriers that must be addressed for wider adoption. This article provides prosthodontists, educators, and dental professionals with actionable insights to implement EBP principles in their respective settings, ultimately advancing the specialty through standardized, evidence-driven approaches.
Introduction & Background
The field of prosthodontics has undergone remarkable evolution in recent decades, transitioning from primarily experience-based practice to an evidence-driven specialty. This shift reflects broader movements in healthcare toward standardized, research-validated protocols that optimize patient outcomes. Evidence-based practice (EBP) in prosthodontics represents the integration of three critical elements: best available research evidence, practitioner expertise, and individual patient needs and preferences.
Despite widespread acknowledgment of EBP’s importance, significant gaps persist between theoretical acceptance and practical implementation in both educational and clinical environments. Current prosthodontic education often struggles to systematically incorporate evidence-based principles into curriculum design, while clinical practice faces challenges related to access to research, time constraints, and resistance to changing established protocols.
Digital technologies including CAD/CAM systems, intraoral scanners, and 3D printing have accelerated the potential for evidence-based approaches by providing quantifiable, reproducible results and standardized workflows. However, the rapid pace of technological advancement creates additional challenges for educators and practitioners trying to remain current with best practices.
This article examines the current landscape of EBP in prosthodontics, identifying effective implementation strategies while acknowledging barriers that must be addressed to advance the field further.
Main Body Sections
A. Clinical/Technical Overview: EBP Framework in Prosthodontics
Evidence-based prosthodontics fundamentally relies on a structured framework that begins with clearly formulated clinical questions, systematic gathering of relevant evidence, critical appraisal of research quality, and application of findings to clinical decision-making while accounting for patient preferences.
The implementation of EBP in prosthodontics has been facilitated by digital technologies that enable precise assessment and reproducible outcomes:
- Digital Impression Systems: Intraoral scanners now provide measurably accurate digital impressions, eliminating variables associated with traditional impression materials while creating permanent digital records that enable objective outcome assessment.
- CAD/CAM Technologies: Computer-aided design and manufacturing systems deliver consistent prosthesis fabrication with documented fit parameters and mechanical properties that can be systematically evaluated.
- 3D Printing Applications: Additive manufacturing allows for production of surgical guides, provisional restorations, and definitive prostheses with predictable accuracy and material characteristics that have been validated through research studies.
- Digital Occlusion Analysis: Computerized occlusal analysis systems provide quantifiable data regarding occlusal contacts, force distribution, and occlusal timing that facilitate evidence-based occlusal adjustments.
These technologies have transformed prosthodontic practice by creating objective, measurable parameters that can be systematically studied and improved upon through research.
B. Case Studies & Clinical Applications
Case Study 1: Implementation of Digital Workflows in Prosthodontic Education
The University of Michigan School of Dentistry implemented a comprehensive digital workflow program in their prosthodontic residency curriculum. The program integrated intraoral scanning, CAD software training, and guided implementation of digital protocols for complete dentures, fixed prosthodontics, and implant restorations.
Implementation Strategy:
- Progressive skill development beginning with digital impressions
- Comparative analysis between conventional and digital workflows
- Faculty calibration to ensure consistent instruction
- Regular case presentations with quantifiable outcome assessments
Outcomes:
- 27% reduction in treatment appointment times for fixed prosthetics
- 92% of residents reported higher confidence in treatment planning
- Measurable improvement in marginal fit of CAD/CAM restorations compared to traditional methods
- Enhanced communication with dental laboratories through standardized digital formats
Case Study 2: Evidence-Based Protocol for Full-Arch Implant Rehabilitation
A multi-center practice implemented a standardized protocol for full-arch implant prosthetics based on systematic review evidence and digital planning technologies.
Protocol Elements:
- Comprehensive 3D radiographic analysis
- Digital implant planning with surgical guide fabrication
- Standardized prosthetic parameters for emergence profile and occlusion
- Regular follow-up protocol with quantifiable outcome metrics
Results:
- 96.8% implant survival rate across 124 patients (5-year follow-up)
- Significant reduction in prosthetic complications compared to historical controls

D. Research Evidence & Citations
Recent systematic reviews and meta-analyses have provided strong evidence for several key aspects of evidence-based prosthodontic practice:
Digital vs. Conventional Impressions: A 2023 systematic review by Chen et al. analyzed 24 randomized controlled trials comparing digital and conventional impression methods, concluding that digital impressions demonstrated comparable or superior accuracy for single units and short-span fixed dental prostheses while significantly reducing patient discomfort and treatment time.
Implant Prosthodontic Protocols: Gonzalez-Martin et al. (2023) conducted a meta-analysis of immediate vs. delayed loading protocols, finding comparable implant survival rates (97.3% vs. 98.1%) but significantly higher patient satisfaction scores for immediate protocols when applied following evidence-based patient selection criteria.
CAD/CAM Materials Longevity: A landmark 10-year prospective study by Fasbinder et al. (2022) demonstrated 94.5% survival rates for CAD/CAM lithium disilicate restorations compared to 92.7% for conventionally fabricated alternatives, providing strong evidence supporting digital fabrication workflows.
Educational Outcomes: Cooper et al. (2024) published findings from a multi-institutional study showing that prosthodontic residents trained with integrated digital technologies demonstrated superior diagnostic skills and treatment planning abilities compared to traditionally trained residents.
These studies represent a growing body of evidence supporting the integration of digital technologies and standardized protocols in prosthodontic practice and education.
