Aggressive periodontitis refers to the multifactorial,severe,&rapidly progressive form of periodontitis,which is primarily but not exclusively affects younger patients.

1. Gingivectomy a) Removes supra gingival pockets b) Removes enlargements c) Removes supragingival abscess d) ALL

Gingivectomy Excision of gingiva by removing the deceased pocket wall thereby exposing tooth surface which provides the visibility and access ability that are essential for the complete removal of irritating surface deposits and thorough smoothening of the roots.

A “root replica” or a “root form” implant is a titanium fixture inserted in the jaw to act as a tooth root and anchors a restoration (single crown, bridge, or denture). The final restoration looks, feels, & functions like a natural tooth.

Orban and Glickman et al (1968): truma from occlusion is defined as when occlusal forces exceed the adaptive capacity of the periodontal tissues , the tissue injury results. This resultant injury is termed as trauma from occlusion.
