A. Proclined upper incisors and increased overjet. B. Retroclined upper central incisors and decreased overjet. C. Normal incisor relationship with a distal molar relationship. D. Prognathic mandible.

Heavy forces compress the PDL to the point of ischemia, causing sterile necrosis (hyalinization). Because the PDL is devoid of living cells, osteoclasts cannot differentiate within it. Instead, they must differentiate from the neighboring bone marrow spaces and attack the lamina dura from behind. This delayed process is known as undermining (or backward) resorption. Light, continuous forces lead to desirable frontal resorption. Why PDF Question Banks are Essential for Exam Prep orthodontics mcqs pdf
