PERIODONTICS-ORTHODONTICS RELATIONSHIP 📌 POINTS TO PONDER 🔹The effects of orthodontic treatment on periodontium are: – Favors plaque accumulation – Modifies the gingival ecosystem – Gingival recession and hyperplasia – Excessive force causes necrosis of periodontal ligament and alveolar bone. 🔹After 4–6 weeks of regenerative osseous therapy, orthodontic treatment can be initiated. 🔹PAOO is contraindicated in […]
DEFINITIONS OF ORTHODONTICS 🔹MALOCCLUSION: Any deviation from normal occlusion. 🔹MOMENT (of a force): The tendency of a force to cause rotation. 🔹NANCE PALATAL ARCH: A maxillary fixed anchorage reinforcing appliance consisting of a wire soldered onto the first molar bands connected to an acrylic button contacting the anterior palatal surface. 🔹NASOLABIAL ANGLE: The angle between […]
🌟 MUST READ DEFINTIONS 🔸FACEMASK: An extra-oral appliance, commonly used in Class III malocclusion, that uses anchorage from the chin and forehead to place anterior forces on the maxillary dentition and/or maxilla. 🔸FIXED APPLIANCE: An appliance that is cemented or bonded onto the teeth and cannot be removed by the patient. 🔸FUNCTIONAL APPLIANCE: A removable or […]
IMPORTANT DEFINITIONS IN ORTHODONTICS 🔸ADAPTIVE SWALLOWING PATTERN: A swallowing pattern that exists when a normal lip-to-lip anterior oral seal cannot be achieved. 🔸ANCHORAGE: The resistance to unwanted three-dimensional forces generated in reaction to the active components of an appliance. 🔸ANGLE CLASSIFICATION: A classification of malocclusion introduced by Edward Angle based on the anteroposterior relationship of […]
DEFINITIONS IN ORTHODONTICS 🔸BINDING: During tooth movement along an archwire, a high couple occurs between bracket and wire, owing to overtipping of the tooth. Binding is the locking of these two materials due to friction. As a result of binding, tooth movement stops. Binding can also occur during sliding of the wire in en masse […]
TOPIC: CLASSIFICATION OF MALOCCLUSIONS 🔹Zygoma (or) Key ridge corresponds to the Mesiobuccal root of the upper 1st molar 🔹A patient is having an edge to edge or end on relation of the first molar in the permanent dentition with retroclined incisors. According to Angle’s classification, this is Class II div I
SHORT NOTES FOR ORTHODONTICS 1. The term orthodontics is coined by Le Foulon 2. The pioneer in the treatment of cleft palate and related problems, Norman Kingsley
TOPIC: GROWTH SPURT 📌 KEY POINTS: Growth does not take place uniformly at all times. This period when a sudden acceleration of growth occurs and this sudden increase in growth is termed ‘Growth Spurts’. Timings of growth spurts differs in boys and girls
TOPIC: JACKSON’S TRIAD 📌 KEY POINTS: The aims and the objectives of orthodontics have been summarized by Jackson as Jackson’s triad. The three main objectives of orthodontic treatment are: Functional efficiency Structural balance Esthetic harmony
