Summary
Neuromodulators effectively treat gummy smiles caused by overactive midface muscles. This study clarifies optimal injection techniques for predictable and reliable management of excess gingival display.
Area of Science:
- Dentistry
- Facial Aesthetics
- Neuromodulation
Background:
- Excess gingival display, or gummy smile, is a common aesthetic concern.
- Neuromodulators are a widely adopted treatment for gummy smile.
- Existing injection algorithms lack universal consensus.
Purpose of the Study:
- To provide a clear and reliable method for managing gummy smiles.
- To clarify optimal neuromodulator placement and dosage for midface muscles.
- To enhance surgical outcomes for gummy smile correction.
Main Methods:
- Review of current neuromodulator injection techniques for gummy smile.
- Analysis of facial anatomy relevant to gingival display.
- Development of a standardized algorithm for neuromodulator administration.
Main Results:
- Identification of key hyperactive midface muscles contributing to gummy smile.
- Establishment of precise injection sites and dosages for neuromodulators.
- Demonstration of predictable reduction in gingival show with the proposed method.
Conclusions:
- A standardized neuromodulator approach offers reliable gummy smile correction.
- Optimal placement and dosage are crucial for successful treatment outcomes.
- This algorithm empowers surgeons to effectively manage excess gingival display.

01:31Skeletal Muscle Relaxants: Therapeutic Uses
525
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

01:26Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
714
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.

01:24Centrally Acting Muscle Relaxants: Therapeutic Uses
757
Centrally acting muscle relaxants reduce muscle tone and tension by interfering with the postsynaptic reflexes in the central nervous system.
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...

01:09Peripherally and Centrally Acting Muscle Relaxants: A Comparison
3.5K
Skeletal muscle relaxants can target the central nervous system [CNS] to reduce muscle tension or act directly at the neuromuscular junction to induce temporary paralysis. These two classes of muscle relaxants are called centrally acting muscle relaxants and peripherally acting muscle relaxants. They differ in their action, mechanism, administration route, and clinical uses.
Centrally acting muscle relaxants can be further divided into spasmolytic and antispasmodic drugs. Spasmolytic...

01:27Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions
469
Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
691
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
