Lesson 1Skin and soft tissue biomechanics: collagen, elastin, and aging changes affecting thread choiceThis part explains how body fiber, stretch fiber, and age skin and fat changes affect tissue hold, bounce back, and thread work, guiding pick of thread kind, amount, and direction for different skin and looseness levels.
Collagen architecture and tensile behaviorElastin, recoil, and skin viscoelasticityIntrinsic and extrinsic aging of facial tissuesMatching thread type to skin thicknessAdapting plans for severe laxity or volume lossLesson 2Material science: PDO, PLLA, PCL thread types—composition, biodegradation timeline, tensile strengthThis part looks at PDO, PLLA, and PCL thread materials, detailing build, break down time, pull strength, and tissue reaction, so doctors can match material to patient aims, skin quality, and last time hopes.
Polymer composition and manufacturing basicsDegradation timelines and byproduct profilesTensile strength and elasticity comparisonsTissue integration and collagen stimulationSelecting material by patient age and goalsLesson 3Sterilization, storage, and shelf-life considerations for thread suppliesThis part reviews clean standards, pack strong, store ways, and use-by time for PDO, PLLA, and PCL threads, helping doctors keep clean, track, and good work while cutting dirt and waste.
Sterilization methods and validation basicsPackaging integrity, seals, and sterility indicatorsOptimal storage temperature, light, and humidityReading labels, lot numbers, and expiry datesInventory rotation, documentation, and recallsLesson 4Selecting thread length, gauge, and anchor configurations for lower face and midfaceThis part covers how to choose thread long, thick, and hold patterns for lower and middle face, mixing direction planning, enter and out points, and tissue thick to get steady lift keeping natural teeth-face match.
Assessing facial proportions and laxity patternsSelecting thread length by treatment vectorGauge selection for support vs subtle refinementAnchor placement for jowls and marionette linesMidface vectors and zygomatic anchoring optionsLesson 5Thread design features: monofilament vs barbed/cog, uni- vs bi-directional barbs, cone threads and anchorsThis part checks how single line, hook, and cone threads differ in build, hold, and tissue touch, and how hook way and hold picks affect lift directions, steady, and problem risk in dental thread lifting.
Monofilament threads: indications and limitationsCog and barbed threads: mechanics and gripUnidirectional vs bidirectional barb configurationsCone threads and soft tissue anchoring pointsChoosing thread design by treatment indicationLesson 6Nerve anatomy: branches of facial nerve, infraorbital and mental nerves and safe corridorsThis part reviews face nerve parts, under eye and chin nerves, and safe paths for tube and needle go, letting dentists avoid move and feel harm while planning enter points and thread paths in lower face.
Main branches of the facial nerve in lower faceInfraorbital nerve course and exit foramenMental nerve anatomy and perioral innervationSurface landmarks for nerve-safe corridorsManaging neuropraxia and nerve irritation risksLesson 7Clinical implications of thread types: lift capacity, inflammatory response, longevity and touch-up planningThis part mixes how thread build and material affect lift power, swell reaction, last time, and fix-up times, helping dentists make real plans, handle hopes, and set times for step or mix therapies.
Lift capacity vs tissue thickness and weightInflammatory response and edema patternsLongevity, resorption, and result fade curvesPlanning touch-ups and maintenance intervalsCombining threads with fillers and toxinsLesson 8Vascular anatomy: facial artery, angular artery, superficial temporal and mental branches and danger zonesThis part details face and corner blood lines, top head and chin parts, and main danger spots, teaching dentists to map blood marks, avoid inside blood harm, and change thread directions to cut blood lack and bruise problems.
Course of facial and angular arteriesSuperficial temporal and transverse facial vesselsMental artery and perioral vascular patternsHigh-risk zones for thread passageStrategies to minimize vascular complicationsLesson 9Relevant facial anatomy for thread lifts: superficial fascia, SMAS, platysma, facial fat compartmentsThis part focuses on clinic useful face layers for thread lifts, including top cover, muscle sheet, neck muscle, and fat areas, stressing safe levels, deep control, and directions for lower face and mouth youth in dental work.
