The first patient to be treated by lingual braces was by Kurz in Beverly Hills in 1976. She was a member of Playboy Bunny Club and after being presented with metal braces option, she wanted to get braces which did not show metal. [4] It was from her demand that Craven developed the lingual braces.
The orthodontist may advise wearing the retainer for a set period of time or indefinitely after orthodontic treatment. Recent innovations of a Smart Retainer Case that utilizes: IoT, motion sensors, and a mobile application to track, remind, and reward patients, might be the most effective way of keeping post-orthodontic patients engaged with ...
Patients may need post-orthodontic surgery, such as a fiberotomy or alternatively a gum lift, to prepare their teeth for retainer use and improve the gumline contours after the braces come off. After braces treatment, patients can use a transparent plate to keep the teeth in alignment for a certain period of time. After treatment, patients ...
While braces correct the position of teeth, orthodontic headgear—which, as the name suggests, is worn on or strapped onto the patient's head—is most often added to orthodontic treatment to help alter the alignment of the jaw, although there are some situations in which such an appliance can help move teeth, particularly molars.
Compression of periodontal ligament near posterior teeth; Extrusion of posterior teeth; Increased lingual bone thickness, decreased buccal bone thickness [13] One of the limits of expansion is the zygomatic buttress. It is known that this anatomical bony complex limits the maxillary expansion posteriorly.
The gaps that the spacers create are necessary to apply certain appliances or braces. There are two common types of expanders used after the spaces have been made. One very primitive, model is a metal bar that has a key used to tighten. Secondly, and more contemporary, there is an expander that is two L-shaped metal rods, attached at the molars ...
A variant in which the acetic acid is replaced with formic acid can be used for both fixation of tissue and decalcification. [3] The effects of the three chemicals in Bouin solution balance each other. Formalin causes cytoplasm to become basophilic but this effect is balanced by the effect of the picric acid.
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
