Stump dental inlay

At the dental prosthetics clinic “Kiadent,” we restore severely damaged teeth with crowns using core buildup posts.

We use durable materials that withstand high chewing loads. Our approach ensures reliable fixation and high aesthetics of the prosthetic structure.

Core Buildup Post — What is it?

This is a fixed structure installed when a tooth is more than ¾ destroyed. It consists of two parts:

Rod — the part fixed in the dental root, provided the walls are strong enough to handle chewing loads.
Artificial core — the external part onto which the crown is fixed.

The shape and appearance of the prosthesis depend on the chosen material, location, and purpose of the damaged tooth. A dental technician models the structure to perfectly match anatomical features and not interfere with adjacent teeth.

Types of Core Buildup Posts by Material

Zirconium

Zirconium rods are installed under metal-free crowns.

They offer high aesthetics and allow the material's shade to be matched individually.

Ceramic

Pressed ceramic, such as E-max, is ideal.

It maintains strength and does not show through the crown. It is suitable for restoring front teeth.

Metal

Gold is the best choice for maintaining aesthetics.

It does not show through the crown and gives a soft yellowish tint. It is also non-allergenic. Another option is titanium. This material is strong and can withstand full chewing loads but might be visible. Metal-ceramics maintain aesthetics but lack the strength of other materials.

Doctor’s Advice

We will conduct diagnostics and provide consultation. We’ll recommend the best option for restoring your tooth with a core buildup post. Additionally, we’ll guide you on the next steps for recovery—choosing a tooth crown. We will also explain the alternative restoration method using a fiberglass post.

Indications and Contraindications

Indications

More than 2/3 of the chewing or front tooth is destroyed.
A base is needed for installing a bridge or a single crown.
Stabilization of a loose tooth due to gum disease.
Correcting the shape or position of a tooth.

Contraindications

Root walls are fragile, cracked, or beginning to deteriorate.
Root canals are too curved or blocked.
Root is too short.
Tooth is excessively loose.

Advantages and Disadvantages of Core Buildup Posts

Advantages

Securely fixed in the root. The rod is custom-made based on the patient’s jaw impression. It fits perfectly into the root canals, providing extra sealing and protection against secondary caries. Compared to posts, it carries a lower risk of root fracture.
Long service life. If the doctor's recommendations are followed, the structure lasts 15–20 years. Even if the artificial crown discolors or breaks, the post does not need replacement.
Even pressure distribution. Chewing load is evenly distributed on the structure, preventing wear and protecting neighboring teeth.

Disadvantages

Long installation process. Creating and fixing the structure requires at least two dental visits—one for impressions and one for securing the post.
High cost. It is more expensive than installing a post with a filling.

We Guarantee Quality Restoration

We use specialized magnification equipment to minimize the risk of error. The doctor will also select the most suitable material for making the post, considering the patient’s anatomical features and preferences.

Steps for Making and Installing a Core Buildup Post

Before creating and installing the fixed structure, the dentist takes an X-ray of the jaw, thoroughly treats the root canals, and seals them. During the first consultation, the dentist prepares the tooth by unsealing the canals partially (⅓ or ⅔) to create an impression or model.

How the Post is Made

There are two methods:

Direct Method
After root canal treatment and sealing, the dentist inserts impression material and waits for it to harden. The hardened model is then sent to a dental lab, and the root canals are temporarily sealed with a filling. The technician uses a wax or plastic sample to create the final structure from the chosen material. This method is suitable for front teeth (with one root) or restoring a small number of teeth.
Indirect Method
The dentist takes an impression (mold) of the root canals. A dental technician uses this to create a plaster model and then the final structure from the chosen material.
For zirconium or ceramic posts, the technician employs CAD/CAM technology. The dentist uses an intraoral scanner to create a 3D model of the root canals, which is loaded into a milling machine that carves the post from a block of material.

How is the Post Installed?

1. Step. Preparation
The dentist sanitizes the oral cavity to prevent infection in the tooth. The temporary filling is removed, the root canals are treated with an antiseptic, and then dried.
2. Step. Fixation
The dentist tries on the structure, adjusts it to ensure it does not interfere with neighboring teeth, and fits tightly into the canals. Excess material is trimmed with a dental drill. The structure is cemented into the root using dental adhesive.
3. Step. Impressions
Excess dental cement is removed, and impressions of the core part are taken to create a crown for the post.

Questions and Answers

Is installing a core buildup post painful?
No. By the time the post is installed, the nerve has been removed from the tooth, and the procedure involves no gum incisions.
Which is better: a post or a core buildup post?
A post is a standard-sized rod on which the dentist creates a core using filling material. A crown of any chosen material can then be fixed on it. However, the risk of post fracture is higher compared to a core buildup post.
When can you do without a core buildup post?
If the natural crown walls are still strong, the dentist can place a microprosthesis to restore the damaged part of the tooth.
If the root is completely destroyed, the tooth can only be restored with an implant, which mimics a natural root and serves as the foundation for a crown.
