APEX – Advanced Perio Excellence is an in-depth online course designed to help clinicians understand the crucial role of periodontal principles within restorative, aesthetic, orthodontic and implant dentistry. The course explores how successful treatment planning requires a multi-disciplinary approach, where aesthetics are only one part of achieving long-term functional, biological and patient-centred outcomes.
Across the course, delegates will develop a deeper understanding of biological width, the complications that can arise when it is compromised, and how to diagnose and manage altered passive eruption using appropriate classification and treatment protocols. The programme also covers the surgical sequence for correcting APE, the role of orthodontics in complex restorative cases, and the management of the non-vital discoloured tooth.
APEX also provides detailed insight into the diagnosis and treatment rationale for single tooth recession, multiple recession defects and root coverage procedures, including flap design, connective tissue grafting and soft tissue management. The course concludes by exploring how soft tissue flap design around dental implants can be used to enhance both the aesthetic and functional outcome of implant treatment.

Lecture 2 - Soft Tissue Assessment Provisionals & Road-Testing Outcomes
Diagnosing soft tissue before replacing crowns; extruded anteriors from cingulum design failure; roadtesting provisionals for phonetics, stops and tissue response; 1-year stable outcome.
Lecture 3 - Biological Width – Introduction, Anatomy & Clinical Importance
Four normal and four abnormal gingival classifications introduced; 3mm BW compartments (connective tissue + junctional epithelium + sulcus); clinical cases illustrating 3mm vs 2mm bone-to-margin; why invasion must be avoided.
Lecture 4 - Normal Crest, Safe Margin Placement & Biotype Responses to Violation
Normal crest present in 85% of patients; 0.5mm subgingival prep rule; thick biotype (inflammation, hyperplasia) vs thin biotype (recession, attachment loss).
Lecture 5 - Bone Sounding Technique & the Kois Classification
Bone sounding method with probe kept on tooth surface; Kois 1996 paper; normal crest (3mm), high crest (1–2mm) and low crest (4mm) defined; high crest danger signs including retraction cord sign
Lecture 6 - Low Crest: Stable vs Unstable Tissue, Thin Phenotype & Classification Recap
Stable low crest (long JE, probe not visible) vs unstable (sulcusdominant, probe visible through tissue); thin phenotype clinical signs; provisionals to convert unstable to stable; management recap for all four Kois types.
Lecture 7 - Altered Passive Eruption – Definition, Prevalence & the Sickle Probe
APE defined as excess gingiva covering enamel coronal to the CEJ; short clinical crowns; 12% prevalence, twice as common in females; sickle probe technique for CEJ detection introduced.
Lecture 8 - APE Classification: Types 1a, 1b, 2a & 2b
Type 1 (adequate KT) vs Type 2 (mucogingival line close to crown); subtype a (bone 3mm from CEJ) vs subtype b (bone at CEJ); treatment per type — gingivectomy, gingivectomy + bone removal, or APF.
Lecture 9 - APE Differential Diagnosis: Gummy Smile, Wear Small Teeth & Diagnostic Limits
Hyperactive lip vs APE vs incisal wear vs small teeth; 10.5mm central reference; sickle probe + perioprobe sequence; two contrasting gummy smile cases — one treatable, one untreatable.
Lecture 10 - APE in Practice: Crown Lengthening to Save an Unrestorable Tooth
Tooth referred for extraction; Type 1a APE confirmed; gingivectomy + provisional + 5-month maturation; 10-year stable outcome; restorative ladder principle reinforced.
Lecture 11 - Clinical Pitfall 1: Crown Replacement Without Bone Sounding
Crown replaced without diagnosis; assumed 85% normal crest; massive BW invasion confirmed 6 weeks post-fit; corrective flap and interproximal bone removal; BW variation occurs tooth-by-tooth in the same patient.
Lecture 12 - Clinical Pitfall 2 : Veneers Placed Without Checking Bone Level PostGingivectomy
Gingivectomy for symmetry followed immediately by veneer prep without bone sounding; bone found at CEJ; massive inflammation from BW invasion; corrective bone removal; 5- year result with minor rebound.
Lecture 13 - APE Surgery: CEJ Marking Gingivectomy Bone Removal & Osteoplasty in Detai
Gummy smile case with bone at CEJ; per-tooth bleeding-point marking; scalpel gingivectomy with papilla definition; raising the flap; osteotomy to 3mm; osteoplasty to contour bone shelf; suturing at CEJ; 6-month result.
Lecture 14 - APE Surgery Cases: Simple Gingivectomy Pre-Ortho Tissue Prep & Diagnosing Inflammation
Second gappy APE case (Type 1a, no bone removal needed); scalpel vs electrosurgery; improved bracket placement post-gingivectomy; third case — differentiating plaqueinduced from BW invasion using bone sounding.
Lecture 15 - Type 2 APE & the Apically Repositioned Flap: Preserving Keratinised Tissue
When insufficient KT band prevents gingivectomy; APF technique: splitthickness papillae to maintain blood supply; suturing at base of papilla (not tip) to gain 2.5mm crown length without cutting tissue.
Lecture 16 - APF Case Example: Bone Removal Papilla Base Suturing & Outcome
APF applied with bone removal; papillae split-thickness preserved; suture tied at papilla base; 2-week result; composite tips for residual wear; black triangle risk if papilla is inadvertently removed.
Lecture 17 - Gum Level Manipulation: Root Reduction Emergence Profile & Slow Orthodontic Principles
Lowering the gum line via root bulk reduction; emergence profile on implants to push or lower gingival margin; slow ortho allows BW to adapt; rapid intrusion/extrusion concept; root resorption warning with duration limits.
Lecture 18 - Crown + Ortho Sequencing: Why Anatomical Temporaries Must Come Before Orthodontics
Ortho on non-anatomical crowns creates false tooth positioning; rotated tooth found only after treatment; correct protocol: remove crowns, fit anatomical temps, then move; wedding-deadline case as cautionary lesson.
Lecture 19 - Complex Ortho-Restorative Case: Bridges Spacing Deep Bite & Bite Raising
Ill-fitting bridges + spacing + deep bite + gummy smile; anatomical temps first; slow anterior intrusion to close spaces; posterior extrusion to open bite; bite-raising appliance for severe deep bite; incisal wear counselling.
Lecture 20 - Advanced Case: Gummy Smile with Bruxism & Evaluating All Treatment Options
Natalie, 26, bruxism, parafunctional wear, mild Type 1a APE, hyperactive lip; gingivectomy insufficient; lip repositioning risks discussed (asymmetry in one third, 50% relapse); veneers contraindicated; rapid intrusion proposed.
Lecture 21 - Rapid Orthodontic Intrusion: Converting Type 1a to 1b Technique & 17-Year Follow-Up

Lecture 22 - Restored Teeth & No Overbite: When Rapid Intrusion Is Contraindicated
