What occlusal change is observed due to transverse relapse?

• A. Closed bite
• B. Open bite
• C. Crossbite
• D. Overjet

Answer: (B)

Transverse relapse most commonly results in an open bite occlusion. This phenomenon occurs when there is a discrepancy in the transverse dimension of the dental arches, typically following treatments aimed at widening the arch or correcting occlusal relationships. During transverse relapse, if the maxillary arch does not maintain its width relative to the mandibular arch, it can lead to a situation where the posterior teeth are unable to make contact during closure, resulting in the characteristic open bite. In contrast, other conditions such as a closed bite, crossbite, or increased overjet typically relate to different occlusal or anatomical discrepancies. A closed bite often suggests a vertical overlap situation, where teeth come together more than they should, while a crossbite indicates an anterior or posterior relationship in which the maxillary teeth fit inside the mandibular teeth. An increased overjet is indicative of a relationship where the incisors are more protruded or retruded than typical, which occurs due to anterior dental relationship discrepancies. Therefore, the specific alteration caused by transverse relapse leading to an open bite is what makes it the correct choice in this context.
