What term describes the malposition and imperfect contact of the mandibular and maxillary teeth?

The term that describes the malposition and imperfect contact of the mandibular and maxillary teeth is "malocclusion." This condition refers specifically to the misalignment of the bite, where the upper and lower teeth do not fit together correctly when the mouth is closed. Malocclusion can affect not just aesthetic appearance but also the function of chewing, speaking, and overall oral health.

In dentistry, malocclusion can be categorized into various types such as overbites, underbites, and crossbites, which can lead to additional complications like tooth wear and jaw pain if not corrected. Recognizing and addressing malocclusion early in dental care is crucial for maintaining a healthy bite and preventing future dental issues. The other terms listed, while related to dental issues, do not specifically capture the complete scope of malocclusion as it pertains to the relationship between the upper and lower teeth.
