**Question:** Which of the following is a major concern for overdenture fabrication?

A. Inadequate retention
B. Insufficient support
C. Poor esthetics
D. Inadequate stability

**Core Concept:** Overdentures are removable partial dentures that replace one or more missing teeth and are retained by attaching to remaining teeth or dental implants. Overdenture fabrication requires addressing retention, support, and stability to ensure optimal function and patient satisfaction.

**Why the Correct Answer is Right:** A major concern for overdenture fabrication is **D. Inadequate stability**. Stability refers to the ability of the overdenture to resist dislodgement during functional or non-functional movements. This is crucial because an unstable denture can lead to discomfort, speech difficulties, and decreased masticatory efficiency.

**Why Each Wrong Option is Incorrect:**

A. **Inadequate retention:** This is not a major concern, as retention is mainly addressed through the use of attachments (ball, bar, or locator attachments) connected to the remaining teeth or dental implants. Overdentures are designed to be removable, so retention is not a significant issue.

B. **Insufficient support:** While ensuring adequate support is essential, it is not as major a concern as stability. Overdentures are designed to be retained by remaining teeth or dental implants, providing support to the oral structures.

C. **Poor esthetics:** Esthetics is an important aspect of dentistry, but it is not the primary concern when fabricating an overdenture. The focus should be on ensuring retention, support, and stability for optimal function and patient satisfaction.

**Clinical Pearl:** Achieving a balance between retention, support, and stability while considering esthetics is crucial when fabricating an overdenture. This ensures the patient can effectively chew, speak, and maintain oral health while enhancing their overall quality of life.
