The Dr. Phil Klein Dental Podcast

In this episode, we go back to the fundamentals. We explore why the inferior alveolar nerve block fails so often, what’s really happening anatomically when patients aren’t getting numb, and how a deeper understanding of these patterns can help clinicians improve both consistency and patient comfort in everyday practice. We’ll also take a closer look at anesthetic selection—specifically the advantages of articaine over lidocaine—and discuss the clinical situations where articaine can make a meaningful difference, and why many clinicians consider it an essential part of their anesthetic armamentarium. Joining us today is Dr. David Isen. He practices in Toronto, Canada, where his anesthesia-based practice focuses on patients who require all levels of sedation, general anesthesia, and advanced local anesthetic techniques—often individuals with special medical needs, dental phobia, or unique challenges with anesthesia.

Are you still planning restorative cases by focusing primarily on individual teeth, or have you started thinking about the entire face? This fundamental shift from tooth-centered to facial-driven treatment planning represents one of the most significant changes happening in modern dentistry.
Dr. Richard Martin brings over two decades of clinical experience as an oral surgeon practicing in Lewisville, Texas since 2002. A graduate of New York University Dental School where he was elected to Omicron Kappa Epsilon and graduated with full honors in Oral Surgery, Dr. Martin completed his residency at Harlem Hospital, Columbia College of Physicians and Surgeons, where he was appointed chief resident. He furthered his training with a one-year Fellowship at the Oral Surgical Institute in Nashville. Beyond his clinical expertise, Dr. Martin is an innovator who has developed more than 20 dental instruments throughout his career.
This episode explores the revolutionary integration of 3D facial scanning technology with traditional digital workflows, demonstrating how facial scanners are transforming treatment planning from a tooth-centered approach to a comprehensive facial-driven methodology. Dr. Martin discusses how these technologies create virtual patients by merging facial scans with CBCT data and intraoral scans, fundamentally changing how dental teams approach interdisciplinary care. The conversation covers practical implementation strategies, laboratory integration, and the clinical impact on case acceptance and treatment outcomes.
Episode Highlights:
Facial scanning technology allows practitioners to capture multiple facial positions including rest, natural smile, and full retraction, providing comprehensive data sets that merge seamlessly with CBCT and intraoral scan data to create complete virtual patient avatars. This integration enables treatment planning that considers facial proportions, midlines, and anatomical relationships beyond just dental structures.
The jaw tracking feature available with certain facial scanners significantly reduces chairside adjustment time for prosthetic deliveries by capturing patient-specific movement patterns and parafunctional habits. This technology allows laboratories to fabricate restorations that require minimal occlusal adjustments, particularly beneficial for patients who are sensitive to bite discrepancies.
Intraoral photogrammetry built into modern scanners eliminates the stitching errors commonly encountered when scanning multiple implants, providing accuracy comparable to extraoral photogrammetry systems but at a fraction of the cost. This technology captures implant positions and surrounding soft tissues in a single workflow without requiring multiple file transfers.
Full arch cases, particularly those involving complete vertical collapse or edentulous situations, benefit most significantly from facial scanning technology as it provides critical reference points for establishing proper vertical dimension and facial support. The technology is equally valuable for extensive tooth-borne restorations involving multiple units in the aesthetic zone.
Successful digital workflow implementation requires comprehensive education through study clubs and online resources, close collaboration with digitally integrated laboratories, and mentorship from experienced practitioners. The transition should include maintaining analog knowledge as a foundation while gradually adopting digital technologies based on practice needs and case complexity.
Perfect for: General dentists, oral surgeons, prosthodontists, and laboratory technicians interested in integrating facial scanning technology into interdisciplinary treatment planning workflows.
Discover how facial-driven treatment planning is reshaping modern restorative dentistry and learn practical strategies for implementing these game-changing technologies in your practice.

This episode addresses how MTA—mineral trioxide aggregate—can be used as both an indirect and direct pulp cap and is ideal for perforations. MTA isn’t just an endodontist's material—it’s very much a general dentist’s material as well. Especially now, as more of us focus on minimally invasive dentistry and are doing everything we can to preserve the natural tooth. Our guest is Dr. Ryan Walsh, who maintains a full time private practice in Keller, TX. He is a Diplomate of the American Board of Endodontics (ABE) and serves on the Scientific Advisory Board of the Journal of Endodontics. Dr. Walsh maintains an appointment as Adjunct Assistant Professor at Texas A&M College of Dentistry and is actively involved in clinical research pertaining to bioactive materials, resorption processes, and clinical outcomes. He has lectured nationally and internationally on several topics in his specialty and has published multiple peer-reviewed articles and abstracts.

What if the secret to transforming traumatic immediate denture experiences lies not in technique alone, but in what happens months before you even pick up the forceps?
Dr. Lori Trost is a comprehensive restorative dentist practicing in Columbia, Illinois, who has revolutionized her approach to immediate dentures through evidence-based nutritional protocols. A recognized dental educator, clinical evaluator for dental manufacturers, and prolific author, Dr. Trost is a member of the ADA, ASDA, and AGD, serves as a board member of the AACO, and was honored as a Shils Foundation Award recipient for entrepreneurial spirit and leadership. She was named one of the "Top 25 Women in Dentistry" by Dental Products Report in 2013, bringing decades of clinical experience to her innovative patient care approach.
This episode explores Dr. Trost's comprehensive nutritional protocol that has dramatically improved healing outcomes for immediate denture patients. After observing patterns of delayed healing and increased discomfort in extraction cases, she developed a three-month pre-surgical regimen targeting bacterial balance, cellular health, and pain management. Her evidence-based approach combines specific probiotic therapy with targeted nutritional supplementation, resulting in faster healing, reduced post-operative discomfort, and improved patient satisfaction.
Episode Highlights:
Strain-specific probiotic therapy using L. reuteri has been clinically proven to promote periodontal healing and bone scaffolding in extraction sites. Patients begin taking one lozenge twice daily three months before extractions, establishing optimal bacterial balance in both gut and oral environments.
Vitamin C supplementation at 1000 milligrams daily addresses widespread deficiencies in immediate denture candidates, particularly smokers who lose 75 milligrams of vitamin C per cigarette consumed. This antioxidant therapy promotes wound healing while blocking histamine release that can interfere with tissue repair.
Quality protein powder supplementation provides essential amino acids including arginine and glutamine that drive cellular metabolism and healing capacity. This becomes critical for patients with compromised dentition who cannot adequately chew protein-rich foods and often rely on high-sugar nutritional drinks.
Socket gel application containing aloe and cloves provides immediate post-extraction comfort when placed inside the immediate denture against extraction sites. This natural product eliminates the need for narcotic prescriptions even in cases involving six to eight extractions per arch while providing slight retention benefits.
Digital denture workflows using intraoral scanning and 3D printing have revolutionized immediate denture accuracy and reduced adjustment appointments. Printed dentures using established resin materials can be fabricated within hours and demonstrate superior fit compared to traditional impression techniques.
Perfect for: General dentists performing extractions and immediate dentures, prosthodontists seeking evidence-based healing protocols, and clinicians interested in integrating nutritional medicine into dental practice.
Discover how this comprehensive approach can transform your most challenging cases into predictable successes while elevating your standard of patient care.
