ovate pontic
Pronunciation: OH-vayt PON-tik
A prosthetic tooth replacement design with an egg-shaped tissue surface that sits within a prepared concavity in the soft tissue, creating the illusion of natural tooth emergence.
Full Definition
An ovate pontic is a specific pontic design used in fixed dental prostheses where the tissue-facing surface is convex and oval, intended to rest within a surgically or orthodontically prepared tissue depression. This design is considered the gold standard for anterior aesthetics because it mimics the appearance of a natural tooth emerging from the gingiva. Dental laboratory technicians must fabricate ovate pontics with precise dimensions to match the prepared tissue site. The term is commonly encountered in laboratory prescriptions and case documentation for aesthetic restorations. Editors should distinguish this from a 'sanitary pontic,' which does not contact tissue at all.
Usage
Usage note: Always lowercase unless beginning a sentence. Distinguish clearly from 'ridge lap pontic' and 'sanitary pontic' in clinical documentation.
