🦷 What is the gum in dental anatomy? The gum is a soft tissue part of the oral cavity that covers the alveolar bone and surrounds the teeth. It is an essential component of the periodontium, the group of tissues that supports the teeth. 📌 Main characteristics: It has a pink color in healthy gums. It is made up of keratinized epithelial tissue (attached gingiva) and non-keratinized epithelial tissue (free gingiva). It is divided into: Free gingiva: Surrounds the neck of the tooth without being attached. Attached gingiva: Firmly attached to the alveolar bone. Interdental papilla: Triangular portion between the teeth. 🩺 Function: Protects the bone and tooth roots. Serves as a barrier against bacteria. Aesthetically, it is important for a harmonious smile. 🧼 How is wax-up done for full dentures? Wax-up is a technique performed on the trial bases of a full denture to simulate the final shape of the teeth and gums. It is used for aesthetic and functional testing before final acrylic processing. 🛠 Materials needed: Working models (upper and lower). Trial bases with wax rollers. Pink wax (base or modeling type). Acrylic teeth for dentures. Hot or electric spatula. Alcohol burner or heat source. Modeling instruments. 🔍 Wax-up steps for full dentures: 1. Tooth assembly: The acrylic teeth are placed on the wax base, guided by the midline, canines, and occlusal planes. Proper alignment and occlusal relationship are ensured. 2. Wax-up of the gums: Pink wax is added around the teeth to simulate the gums. Anatomical shapes are created: interdental papillae, natural scalloping, and relief. The wax is smoothed and polished to give a realistic, aesthetic appearance. 3. Aesthetic try-in (optional): The patient is brought in to check phonetics, aesthetics, smile, and function. Adjustments are made if necessary. 4. Finalization: Once approved, the wax-up is taken to the laboratory for the acrylic coating and pressing process. 🎓 Tips for a good wax-up: Imitate natural anatomy: gingival scalloping, ridges, and papillae. Ensure symmetry and occlusion. Use a warm spatula for precise shaping. Keep the wax clean.
