Explanation: Implant-supported prostheses have the advantage of maintaining alveolar bone due to osseointegration. This helps preserve the natural bone structure and reduces the risk of bone resorption that is common with traditional complete dentures, which can lead to changes in the patient's facial profile over time.

While guiding planes are the primary elements that dictate the path of insertion and removal, the minor connector also plays a role. The minor connector helps in the overall stability and retention of the RPD by linking the major connector to the abutment tooth and distributing the forces more evenly across the denture base. However, its primary function is not to guide the path of insertion and removal as much as it is to provide additional support and strength to the RPD.

The PTT (Partial Thromboplastin Time) is prolonged in deficiencies of factors VIII, IX, and XII, which are part of the intrinsic pathway of the coagulation cascade. Since factor VIII deficiency is more common and is associated with a bleeding diathesis, it is the most likely deficiency in this scenario.

Aggressive periodontitis is characterized by rapid attachment loss and bone destruction, but the amount of microbial deposits (plaque and calculus) is typically inconsistent with the severity of the destruction, often appearing minimal. The other options (deep pockets in all areas, increased mobility without clinical signs, widespread gingival recession) are general signs of periodontal disease but not specific diagnostic features that differentiate aggressive from chronic forms.
