Which of the following pontic design is non-mucosal type?
**Core Concept**
A pontic design in fixed prosthodontics refers to the shape and structure of the artificial tooth replacing a missing natural tooth in a dental bridge. Pontics can be classified into two main types: mucosal and non-mucosal. The mucosal type is further divided into three subcategories: ovate, modified ovate, and sankey pontic, all of which come into contact with the mucosa. In contrast, non-mucosal pontics do not come into contact with the mucosa and are typically designed for areas with high aesthetic demands.
**Why the Correct Answer is Right**
Non-mucosal pontics, such as the **saddle pontic**, are designed to avoid contact with the mucosa, reducing the risk of tissue irritation and promoting a more aesthetic appearance. These pontics are usually used in areas with high aesthetic demands, such as the anterior region. The lack of mucosal contact also facilitates easier oral hygiene and reduces the risk of tissue overgrowth.
**Why Each Wrong Option is Incorrect**
**Option A:** Ovate pontic is a mucosal type, as it comes into contact with the mucosa.
**Option B:** Modified ovate pontic is also a mucosal type, sharing similarities with the ovate pontic but with a more conservative approach.
**Option C:** Sankey pontic is another mucosal type, characterized by its unique design that allows for tissue adaptation.
**Clinical Pearl / High-Yield Fact**
When selecting a pontic design, clinicians should consider the patient's oral hygiene needs, aesthetic demands, and tissue health to choose the most suitable option.
**Correct Answer: C. Sankey pontic**
