Detailed Show Notes Episode Overview In part one of this two-part series on Dental Digest, host Dr. Melissa Seibert sits down with dual-boarded periodontist and prosthodontist Dr. Ashley Hoders to examine the latest consensus literature on peri-implant soft tissue deficiencies, biologic bone preservation, and the biomechanics of skeletal expansion . They unpack why soft tissue recession is fundamentally a bone problem, how thin tissue starved of blood supply triggers crestal loss, and why treating skeletal arch deficiencies with dental compensation compromises cortical bone . Guest Information Guest: Dr. Ashley Hoders, DDS, MS Credentials & Affiliations: Dual board-certified diplomat and fellow of the American Board of Periodontology and the American Board of Prosthodontics; MS from UT Health Science Center at San Antonio . Clinical researcher with the McGuire Institute, co-creator of Spear Hygiene, visiting faculty at the University of Washington Graduate Periodontics Department, and active member of the American Academy of Restorative Dentistry (AARD) . Key Clinical Takeaways 1. The Reality of Peri-Implant Soft Tissue Deficiencies Recent joint consensus papers (AO/AAP) reveal that non-diseased peri-implant soft tissue deficiencies have an overall prevalence of 46.2% . These deficiencies worsen over time: 33% at 1 year and 64.5% at 5 years . Clinicians should exercise caution when planning implants in the aesthetic zone and consider alternative modalities (such as resin-bonded bridges) when appropriate . 2. Mid-Facial Margins vs. Interproximal Papilla Interproximal papilla height is dictated primarily by the bone levels on adjacent natural teeth . Mid-facial mucosal margin stability is driven by facial bone thickness (which is frequently $<1\text{ mm}$), 3D implant positioning, and placement timing (immediate vs. delayed protocols) . 3. Soft Tissue Recession is an Underlying Bone Problem Soft tissue recession or peri-implant deficiency cannot occur without an underlying bone dehiscence or bone loss . Bone requires two primary conditions to remain stable : Vascular Nutrition: Thin tissue has inadequate blood supply, starving the underlying crestal bone and causing progressive remodeling . Absence of Tension: Muscle attachments, vestibular pull, and lack of keratinized tissue exert tensile forces that destabilize bone . 4. Proactive Grafting as a Bone Stabilizer Because bone cannot be predictably regenerated over an avascular implant surface or root dehiscence, soft tissue grafting serves as a proactive biologic shield . Converting thin phenotypes to thick biotypes and widening keratinized mucosa delivers blood supply and buffers muscle tension, safeguarding crestal bone before recession occurs . 5. Skeletal Solutions for Skeletal Discrepancies Post-industrial human development (diet changes, decreased breastfeeding) has led to smaller maxillas and contracted arches . Treating skeletal constriction with purely dental expansion tips teeth outside the cortical plate, causing bone dehiscences, severe recession, and mobility . Skeletal discrepancies require orthopedic/skeletal solutions (e.g., MARPE) rather than dental camouflage to preserve the periodontal foundation . 6. Patient Communication & Treatment Planning Utilize 2D/3D radiographs alongside high-quality clinical photographs at baseline . Drawing directly on printed photos helps patients visualize bone anatomy, soft tissue margins, and long-term aesthetic trade-offs before consenting to anterior implant therapy . Notable Mentions & Literature Consensus Literature: Academy of Osseointegration (AO) and American Academy of Periodontology (AAP) consensus papers on peri-implant disease and soft tissue deficiencies . Influences & Citations: Kevin Murphy (AARD literature review), Joseph Kan (interproximal bone dynamics), Mariana Evans (airway, cranial growth, and post-industrial skeletal changes), Jeff Rouse, and Bill Robbins (interdisciplinary diagnosis)
