dental code for 3/4 crown

When it comes to dental restorations, crowns are among the most common solutions for damaged or weakened teeth. However, not all crowns are the same. Among the various types, the 3/4 crown (also known as a partial crown) stands out as a conservative yet durable option.

Dental professionals use Current Dental Terminology (CDT) code D2750 to classify and bill for 3/4 crowns. This guide will explore everything you need to know about this procedure—from its clinical applications to insurance billing—ensuring both dental practitioners and patients make informed decisions.

2. What is a 3/4 Crown?

A 3/4 crown is a type of dental restoration that covers three-quarters of a tooth’s structure, leaving the facial (front) portion intact. Unlike a full crown, which encases the entire tooth, a 3/4 crown preserves more natural tooth structure, making it a less invasive option.

Key Features:

• Covers the occlusal (biting), lingual (tongue-side), and proximal (side) surfaces

• Leaves the buccal (cheek-side) surface mostly untouched

• Typically used on posterior teeth (molars and premolars)

3. Indications for a 3/4 Crown

A dentist may recommend a 3/4 crown in cases where:

✅ Moderate tooth decay affects multiple surfaces but spares the front
✅ Fractured cusps need reinforcement without full coverage
✅ Large fillings weaken the tooth but don’t require a full crown
✅ Aesthetic concerns (since it preserves more natural tooth appearance)

4. Contraindications for a 3/4 Crown

While beneficial, 3/4 crowns are not suitable for all cases, including:

❌ Severe tooth decay requiring full coverage
❌ Teeth with extensive fractures
❌ Patients with bruxism (teeth grinding) needing stronger protection
❌ Poor oral hygiene, increasing risk of recurrent decay
