**Core Concept:** The Endorez system is a dental implant system that uses a screw-in implant with a connecting abutment that is cemented to the dental prosthesis. The system aims to provide a stable and long-lasting solution for dental prostheses and is designed to mimic the natural structure of teeth.

**Why the Correct Answer is Right:**

The Endorez system is an example of a cement-retained implant-supported prosthesis because the connecting abutment is cemented to the dental prosthesis, ensuring stability and retention. In contrast, the Branemark system, a well-known dental implant system, uses a screw-in implant with an osseointegrated connection, which makes it an example of a screw-retained implant-supported prosthesis.

**Why Each Wrong Option is Incorrect:**

A. This option is incorrect because the Endorez system uses cement for retention, not surgery. The focus is on cementing the prosthesis to the abutment, not on surgical implantation.

B. Although the Endorez system involves cementation, it is not specifically designed for "surgical" applications. The focus is on the retention mechanism, not the surgical aspect.

C. This option is incorrect because the Endorez system uses cement for retention, not a "screw-retained" connection. The system focuses on the cemented abutment and prosthesis, rather than a screw-in implant.

D. This answer is incorrect because the Endorez system employs cementation for retention, not a "screw-retained" design. The key feature of the Endorez system is the cemented abutment and prosthesis, not a screw-in implant.

**Clinical Pearl:** In choosing a dental implant system, clinicians should consider factors such as retention method, surgical approach, and the overall stability of the implant-supported prosthesis. Each system has unique features, and selecting the right one depends on the specific patient's needs, treatment goals, and the dentist's preference.

**Core Concept Explanation:**

The Endorez system is a type of dental implant system designed for the retention of prostheses. In this system, the prosthesis is attached to a cement-retained abutment, which is then cemented onto the implant. This cement-retained method ensures a secure and stable connection between the implant and prosthesis, providing a reliable solution for patients in need of dental prosthetics.

**Why Each Wrong Option is Incorrect:**

A. The Branemark system (option A) is a well-known dental implant system that utilizes a screw-retained connection between the implant and prosthesis. This option is incorrect because it refers to a different retention method (screw-retention) than the Endorez system, which employs cement-retention.

B. This answer is incorrect because the Endorez system (option B) focuses on the cemented abutment and prosthesis, not the surgical approach. The Branemark system (option A) is a surgical approach, while the Endorez system focuses on the retention method.

C. This answer is
