Microsurgical Repair Principles Timing: Primary repair (immediate) vs secondary repair (delayed) Tension-free approximation: Essential for successful repair Precise fascicular alignment: Critical for functional recovery Microsurgical technique: 8-0 to 10-0 non-absorbable sutures Epineural Suturing Indication: Pure sensory nerves (like inferior alveolar nerve) Technique: Sutures placed through epineurium only Advantages: Simp…

IONIZATION OF WATER, WEAK ACIDS AND WEAK BASES The ionization of water can be described by an equilibrium constant. When weak acids or weak bases are dissolved in water, they can contribute H+ by ionizing (if acids) or consume H+ by being protonated (if bases). These processes are also governed by equilibrium constants Water molecules have a slight tendency to undergo reversible ionization to yield a hydrogen ion and a hydroxide ion : H2O = H+ + OH− …

Most Tested Anatomical Points Retromolar pad contents - specific muscle composition Coronoid process influence - distobuccal border limitation Levator anguli oris - buccal frenum muscle Masseteric notch formation - muscle relationship Critical Impression Concepts Glossy wax = proper tissue contact Butt joint = inadequate flow/seal Addition silicone = submucous fibrosis material Snow shoe effect = support enhancement Functional Relationsh…

Cartilage model is covered with perichondrium that is converted to periosteum Diaphysis-central shaft Epiphysis-located at either end of the diaphysis Growth in length of the bone is provided by the emetaphyseal plate located between the epiphyseal cartilage and the diaphysis Blood capillaries and the mesenchymal cells infiltrate the spaces left by the destroyed chondrocytes Osteoblasts are derived from the undifferentiated cells; form a…
