Jaw Relation Records refers to the dental records used to determine the optimal jaw position for dental treatment. The spelling of this word can be explained using the International Phonetic Alphabet (IPA) phonetic transcription. The first word, Jaw (dʒɔː), is pronounced with a soft 'j' sound followed by the long 'o' vowel sound. Relation (rɪˈleɪʃən) is pronounced with a short 'i' sound followed by the schwa sound, 'ə', and then the long 'a' vowel sound. Records (rɛkɔrdz) is pronounced with a short 'e' sound followed by the 'k' and then the short 'o' sound, and finally, the letter 's' at the end is pronounced as a 'z'.
Jaw relation records refer to a set of records or measurements that are taken to establish the relationship between the upper and lower jaws in dentistry. These records are essential in the field of prosthodontics as they provide crucial information for the fabrication and fitting of dental prostheses such as dentures.
In order to achieve optimal oral function and aesthetics, it is important to accurately capture and replicate the relationship between the upper and lower jaws. Jaw relation records help in this process by capturing the spatial and positional relationship of the jaws in various functional positions such as biting, chewing, and speaking.
The process of recording jaw relations involves utilizing various techniques and materials. These can include bite registration materials such as wax, silicone, or acrylic, which are placed on the occlusal surfaces of the teeth to record the patient's bite. Additionally, instruments like articulators are often used to simulate the patient's jaw movements and aid in accurately transferring the recorded jaw relations to the dental laboratory.
Jaw relation records serve as a guide for dental professionals when fabricating dental prostheses. By accurately capturing the jaw relationship, these records help ensure that the final prosthesis fits properly, allowing for comfortable chewing, speaking, and a natural-looking smile.
