PTERYGOID RIDGE Meaning and
Definition
-
The term "pterygoid ridge" refers to a prominent bony ridge in the human skull located in the posterior region of the mouth. Specifically, it is the ridge that extends horizontally from the lateral pterygoid plate of the sphenoid bone towards the back of the oral cavity. The pterygoid ridge runs parallel to the upper dental arch and serves as an attachment site for several muscles involved in jaw movement and chewing.
This anatomical structure is comprised of dense cortical bone and is known for its robustness. It plays a vital role in stabilizing the temporomandibular joint (TMJ) and controlling the movements of the mandible during mastication. The pterygoid ridge also provides support for other soft tissues in the oral and pharyngeal regions.
Furthermore, the pterygoid ridge serves as an important reference landmark in dental and maxillofacial surgery. Its location and shape are considered essential during dental implant placement procedures, as implants need to be anchored securely into this ridge for successful osseointegration. The depth and width of the pterygoid ridge are evaluated preoperatively to ensure appropriate implant selection and prevent complications.
Overall, the pterygoid ridge represents a significant anatomical feature in the human skull, crucial for jaw movement, oral function, and dental implantology.

Etymology of PTERYGOID RIDGE
The word "pterygoid" originates from the Greek word "pteryx", which means "wing" or "fin". The term "ridge" refers to a long, narrow elevated part or crest on a surface. Therefore, the etymology of "pterygoid ridge" can be understood as follows: "pterygoid" denotes that it is related to the pterygoid bone or process, which resembles a wing, and "ridge" indicates the elevated part or crest-like structure formed by this bone or process.
