Class 1 malocclusion is characterized by what?

• A. Poor alignment of all teeth
• B. Normal molar relationship with possible crowding
• C. Overbite alignment of the incisors
• D. An excessive overjet

Answer: (B)

Class 1 malocclusion is characterized by a normal molar relationship where the first molar of the lower jaw aligns complementary to the first molar of the upper jaw. In this class of malocclusion, the primary issue often lies in the positioning of the teeth rather than the overall dental relationships; this can include crowding, spacing, or other dental irregularities. This means that while the molars may fit together properly, there can still be individual teeth that are not aligned well, which can lead to issues such as crowding or rotations. Therefore, the distinction of having a normal molar relationship is crucial to defining Class 1 malocclusion, making option B the correct answer. Understanding this classification helps in diagnosing orthodontic needs, as a practitioner can identify the specific issues affecting the patient's dental alignment while maintaining an intact molar relationship.
