Rappoel Dermatology uses Coretox to precisely relax the masseter \u2014 3-day onset for grinding reduction and facial slimming<\/div>\n<\/p><\/div>\n<p>Sleep bruxism refers to the unconscious habit of clenching or grinding teeth during sleep \u2014 studies show approximately 10-15% of adults have nocturnal bruxism. Nighttime grinding not only causes severe enamel wear, tooth sensitivity, and temporomandibular joint (TMJ) pain, but also leads to masseter muscle over-enlargement \u2014 the masseter is the chewing muscle at the jaw angle, and long-term nocturnal over-contraction makes it increasingly hypertrophic, widening the jaw angle and changing the face from oval to square. Causes of sleep bruxism are multifactorial: (1) Psychological stress \u2014 anxiety, tension, and high stress keep the brain excited during sleep, causing unconscious chewing muscle contraction. (2) Malocclusion \u2014 abnormal bite relationship keeps chewing muscles under high tension at rest. (3) Sleep apnea \u2014 bruxism incidence is significantly higher in sleep apnea patients, possibly the brain attempting to open the airway through chewing muscle activity. (4) Lifestyle factors \u2014 excessive caffeine, pre-sleep alcohol, and smoking aggravate bruxism. Rappoel Dermatology near Gangnam Station, Seoul, uses Coretox \u2014 precise masseter injection to relax overactive chewing muscles, with 3-day onset for grinding reduction and masseter slimming.<\/p>\n<h2>Technical Principles of Coretox Bruxism Treatment<\/h2>\n<ul>\n<li><strong>Botox relaxes the masseter:<\/strong> Coretox is botulinum toxin type A \u2014 when injected into the masseter, it blocks acetylcholine release at the neuromuscular junction, moderately relaxing the overactive muscle. After relaxation, grinding force and frequency significantly decrease \u2014 clinical data shows 50-80% reduction in grinding episodes at 1-2 weeks<\/li>\n<li><strong>Coretox Korean-origin high-purity advantage:<\/strong> Coretox is 150kDa high-purity toxin with unnecessary complex proteins removed, reducing antibody formation and resistance risk. Masseter treatment requires sufficient dose for effective relaxation \u2014 high-purity formulation ensures sustained efficacy with long-term repeated injections<\/li>\n<li><strong>Fast onset (2-3 days):<\/strong> Coretox clinical data shows average onset of 2-3 days \u2014 the masseter begins relaxing at 3-5 days, with optimal results at 1-2 weeks. Patients typically notice grinding reduction and masseter softening within one week<\/li>\n<li><strong>Dual effect \u2014 grinding treatment + masseter slimming:<\/strong> Coretox masseter injection achieves two goals simultaneously: (1) Relaxing the masseter reduces nocturnal grinding force and frequency, protecting teeth and TMJ; (2) Post-relaxation masseter gradually atrophies and shrinks, narrowing the jaw angle from wide to slim, restoring the face from square to oval<\/li>\n<li><strong>Preservative-free hypoallergenic formulation:<\/strong> Coretox contains no animal-derived proteins or human serum albumin \u2014 reducing allergic reaction risk<\/li>\n<\/ul>\n<h2>Treatment Strategies for Different Bruxism Types<\/h2>\n<ul>\n<li><strong>Stress-related bruxism (most common):<\/strong> Daytime stress, anxiety, with nocturnal unconscious grinding. Masseter typically mild to moderately enlarged. Strategy: inject Coretox 25-40 units per side (bilateral total 50-80 units), relaxing the masseter to improve grinding. Recommend concurrent stress management (exercise, meditation) for enhanced efficacy<\/li>\n<li><strong>Severe masseter hypertrophy type:<\/strong> Long-term grinding causing severe masseter enlargement, with obviously widened jaw angle forming a square face. Strategy: inject Coretox 40-60 units per side (bilateral total 80-120 units), higher dose ensuring sufficient relaxation and atrophy. Reassess masseter reduction at 3-4 months, supplement if needed<\/li>\n<li><strong>TMJ pain type:<\/strong> Grinding accompanied by TMJ pain, limited mouth opening, joint clicking. Strategy: Beyond masseter injection, inject appropriate Coretox into the temporalis and lateral pterygoid (additional 10-20 units per side), relaxing the muscle groups involved in chewing. Recommend concurrent dental evaluation for occlusion issues<\/li>\n<li><strong>Severe enamel wear type:<\/strong> Bruxism has caused severe enamel wear and tooth sensitivity. Strategy: Coretox masseter injection (30-50 units per side), reducing nocturnal grinding force to protect remaining teeth. Recommend concurrent dental night guard fabrication for dual tooth protection<\/li>\n<li><strong>Sleep apnea-related type:<\/strong> Bruxism may be related to sleep apnea \u2014 the brain attempting to open the airway through chewing muscle activity. Strategy: Coretox masseter injection to improve grinding (25-40 units per side), but concurrent ENT or sleep medicine evaluation for sleep apnea is needed. If sleep apnea is treated (e.g., CPAP), bruxism typically improves significantly<\/li>\n<\/ul>\n<h2>Rappoel Bruxism Coretox Injection Treatment Protocol<\/h2>\n<ol>\n<li><strong>Bruxism assessment and plan design (10 min):<\/strong> Inquire about grinding habits (frequency, duration, TMJ pain) \u2192 examine tooth wear degree \u2192 palpate masseter size and firmness \u2192 photograph masseter morphology \u2192 establish injection plan (dosage, points)<\/li>\n<li><strong>Disinfection preparation (3 min):<\/strong> Facial cleansing \u2192 alcohol swab preparation of jaw angle masseter area \u2192 mark injection points (3-5 points per side, at the thickest masseter area in the safe zone, avoiding the marginal mandibular branch of the facial nerve)<\/li>\n<li><strong>Precise injection (5-8 min):<\/strong> 32G ultra-fine needle \u2192 3-5 injection points per side \u2192 8-15 units Coretox per point \u2192 deep masseter injection (intramuscular) \u2192 gentle pressure after injection \u2192 bilateral total 50-120 units (adjusted by masseter hypertrophy degree)<\/li>\n<li><strong>Immediate assessment and guidance (5 min):<\/strong> Patient clenches to confirm normal masseter contraction \u2192 post-care instructions (avoid pressing injection area, avoid lying flat for 4 hours, avoid strenuous exercise for 24 hours, avoid massager massage for 1 week) \u2192 2-week follow-up<\/li>\n<\/ol>\n<p>The entire bruxism Coretox injection takes about 15-20 minutes, with onset at 3-5 days, optimal results at 1-2 weeks, lasting 3-4 months.

Rappoel Dermatology uses Coretox to precisely relax the masseter \u2014 3-day onset for grinding reduction and facial slimming<\/div>\n<\/p><\/div>\n<p>Sleep bruxism refers to the unconscious habit of clenching or grinding teeth during sleep \u2014 studies show approximately 10-15% of adults have nocturnal bruxism. Nighttime grinding not only causes severe enamel wear, tooth sensitivity, and temporomandibular joint (TMJ) pain, but also leads to masseter muscle over-enlargement \u2014 the masseter is the chewing muscle at the jaw angle, and long-term nocturnal over-contraction makes it increasingly hypertrophic, widening the jaw angle and changing the face from oval to square. Causes of sleep bruxism are multifactorial: (1) Psychological stress \u2014 anxiety, tension, and high stress keep the brain excited during sleep, causing unconscious chewing muscle contraction. (2) Malocclusion \u2014 abnormal bite relationship keeps chewing muscles under high tension at rest. (3) Sleep apnea \u2014 bruxism incidence is significantly higher in sleep apnea patients, possibly the brain attempting to open the airway through chewing muscle activity. (4) Lifestyle factors \u2014 excessive caffeine, pre-sleep alcohol, and smoking aggravate bruxism. Rappoel Dermatology near Gangnam Station, Seoul, uses Coretox \u2014 precise masseter injection to relax overactive chewing muscles, with 3-day onset for grinding reduction and masseter slimming.<\/p>\n<h2>Technical Principles of Coretox Bruxism Treatment<\/h2>\n<ul>\n<li><strong>Botox relaxes the masseter:<\/strong> Coretox is botulinum toxin type A \u2014 when injected into the masseter, it blocks acetylcholine release at the neuromuscular junction, moderately relaxing the overactive muscle. After relaxation, grinding force and frequency significantly decrease \u2014 clinical data shows 50-80% reduction in grinding episodes at 1-2 weeks<\/li>\n<li><strong>Coretox Korean-origin high-purity advantage:<\/strong> Coretox is 150kDa high-purity toxin with unnecessary complex proteins removed, reducing antibody formation and resistance risk. Masseter treatment requires sufficient dose for effective relaxation \u2014 high-purity formulation ensures sustained efficacy with long-term repeated injections<\/li>\n<li><strong>Fast onset (2-3 days):<\/strong> Coretox clinical data shows average onset of 2-3 days \u2014 the masseter begins relaxing at 3-5 days, with optimal results at 1-2 weeks. Patients typically notice grinding reduction and masseter softening within one week<\/li>\n<li><strong>Dual effect \u2014 grinding treatment + masseter slimming:<\/strong> Coretox masseter injection achieves two goals simultaneously: (1) Relaxing the masseter reduces nocturnal grinding force and frequency, protecting teeth and TMJ; (2) Post-relaxation masseter gradually atrophies and shrinks, narrowing the jaw angle from wide to slim, restoring the face from square to oval<\/li>\n<li><strong>Preservative-free hypoallergenic formulation:<\/strong> Coretox contains no animal-derived proteins or human serum albumin \u2014 reducing allergic reaction risk<\/li>\n<\/ul>\n<h2>Treatment Strategies for Different Bruxism Types<\/h2>\n<ul>\n<li><strong>Stress-related bruxism (most common):<\/strong> Daytime stress, anxiety, with nocturnal unconscious grinding. Masseter typically mild to moderately enlarged. Strategy: inject Coretox 25-40 units per side (bilateral total 50-80 units), relaxing the masseter to improve grinding. Recommend concurrent stress management (exercise, meditation) for enhanced efficacy<\/li>\n<li><strong>Severe masseter hypertrophy type:<\/strong> Long-term grinding causing severe masseter enlargement, with obviously widened jaw angle forming a square face. Strategy: inject Coretox 40-60 units per side (bilateral total 80-120 units), higher dose ensuring sufficient relaxation and atrophy. Reassess masseter reduction at 3-4 months, supplement if needed<\/li>\n<li><strong>TMJ pain type:<\/strong> Grinding accompanied by TMJ pain, limited mouth opening, joint clicking. Strategy: Beyond masseter injection, inject appropriate Coretox into the temporalis and lateral pterygoid (additional 10-20 units per side), relaxing the muscle groups involved in chewing. Recommend concurrent dental evaluation for occlusion issues<\/li>\n<li><strong>Severe enamel wear type:<\/strong> Bruxism has caused severe enamel wear and tooth sensitivity. Strategy: Coretox masseter injection (30-50 units per side), reducing nocturnal grinding force to protect remaining teeth. Recommend concurrent dental night guard fabrication for dual tooth protection<\/li>\n<li><strong>Sleep apnea-related type:<\/strong> Bruxism may be related to sleep apnea \u2014 the brain attempting to open the airway through chewing muscle activity. Strategy: Coretox masseter injection to improve grinding (25-40 units per side), but concurrent ENT or sleep medicine evaluation for sleep apnea is needed. If sleep apnea is treated (e.g., CPAP), bruxism typically improves significantly<\/li>\n<\/ul>\n<h2>Rappoel Bruxism Coretox Injection Treatment Protocol<\/h2>\n<ol>\n<li><strong>Bruxism assessment and plan design (10 min):<\/strong> Inquire about grinding habits (frequency, duration, TMJ pain) \u2192 examine tooth wear degree \u2192 palpate masseter size and firmness \u2192 photograph masseter morphology \u2192 establish injection plan (dosage, points)<\/li>\n<li><strong>Disinfection preparation (3 min):<\/strong> Facial cleansing \u2192 alcohol swab preparation of jaw angle masseter area \u2192 mark injection points (3-5 points per side, at the thickest masseter area in the safe zone, avoiding the marginal mandibular branch of the facial nerve)<\/li>\n<li><strong>Precise injection (5-8 min):<\/strong> 32G ultra-fine needle \u2192 3-5 injection points per side \u2192 8-15 units Coretox per point \u2192 deep masseter injection (intramuscular) \u2192 gentle pressure after injection \u2192 bilateral total 50-120 units (adjusted by masseter hypertrophy degree)<\/li>\n<li><strong>Immediate assessment and guidance (5 min):<\/strong> Patient clenches to confirm normal masseter contraction \u2192 post-care instructions (avoid pressing injection area, avoid lying flat for 4 hours, avoid strenuous exercise for 24 hours, avoid massager massage for 1 week) \u2192 2-week follow-up<\/li>\n<\/ol>\n<p>The entire bruxism Coretox injection takes about 15-20 minutes, with onset at 3-5 days, optimal results at 1-2 weeks, lasting 3-4 months.
