This presentation will present the effects of the application of a permanent intraoral device (PID) on condyles with condylar hyperplasia (CH) validated by a single photon emission computed tomography (SPECT/CT), and to compare it with a group of patients with CH who did not use such device. Thirty patients with a mean age of 21.7 years with CH validated by SPECT/CT were randomly divided into two groups: the ones in group I received an intraoral device for permanent use to align the jaw, while those in group II did not receive any device. Pain, midline shift, maximal opening, and discomfort were evaluated at the beginning of the study and subsequent months. The application of a PID could favor the evolution of condylar hyperplasia, which may serve as a useful treatment until a high condylar neck condylectomy is performed, or it may even prevent this procedure.
Learning Objectives:
After this session, attendees will be able to:
Demonstrate the importance of requesting a spect study in cases of asymmetry.
Show that a splint can decompress the TMJ.
Demonstrate that decompression of the TMJ could modify the osteoblastic activity of a condyle with condylar hyperplasia.
