Lesson 1Skin and soft tissue biomechanics: collagen, elastin, and aging changes affecting thread choiceThis part explains how body proteins, stretch fibers, and age skin and fat shifts affect tissue hold, bounce back, and thread work, guiding choice of thread kind, amount, and pull 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 stuffs, explaining build, break-down time, pull strength, and body reaction, so doctors match properties to patient aims, skin state, and lasting needs.
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 checks cleaning rules, pack safety, keep conditions, and use-by dates 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 picking thread size, thickness, and hold setups for lower and middle face, mixing pull plans, enter and out points, and tissue thick to get steady lift keeping natural mouth-face match.

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 stuff affect lift power, swelling reaction, lasting, and fix times, helping dentists make real plans, handle hopes, and set 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 arteries, top head and chin branches, and main risk spots, teaching dentists to map blood paths, avoid inside harm, and change thread pulls 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 key face layers for thread lifts, like top cover, muscle sheet, neck muscle, and fat pockets, stressing safe levels, depth hold, and pulls for lower face and mouth youth in dental work.
