Types of Acquired Maxillary Defects- Resection of one or a part of the maxilla or palate is considered as Partial Maxillectomy. Aramany proposed a classification of partial maxillary defect based on their extent. 

P Class 1- It is a unilateral defect involving one half of the arch and the adjacent palatine shelf. The defect extends to the mid line (all the teeth in that side of the arch are missing)

Class 11- It is a unilateral defect involving one side of the arch posterior to the canine (teeth posterior to canine are absent).

> Class 111- It is a defect involving the center of palatine shelves (all teeth are present)

>- Class IV- It Is the bilateral defect involving the one side of the arch along with the entire premaxilla (all anteriors along with the posteriors of one side are missing).

> Class V- It is the bilateral posterior defect (teeth anterior to the second premolar are present).

> Class VI- It is the bilateral anterior defect (teeth anterior to the second premolar are absent).
