POST & CORE:

Dental Post and Dental Core is a dental restoration used to sufficiently build-up tooth structure for future restoration like when there is not enough tooth structure to properly retain the crown. The Dental Post is placed within the body of the root of a tooth that has already treated with root canal treatment. The Dental Core is the part of the restoration that shows out in the mouth that helps anchor a cap or crown. Maximum protection is provided to root Adequate retention within root Maximum retention of the core and the crown. There are clinical situations where the remaining tooth structure of an endodontically treated tooth is inadequate to effectively retain the crown. In such cases, dental post and core restoration are indicated to sufficient build-up the tooth structure. Clinicians have written about the placement of posts in the roots of the teeth in order to retain restorations for over 250 years. Pierre Fauchard, in 1728 described the use of “tenons”, metal posts which were screwed into the roots of teeth to aid in the retention of bridges. As time progressed, in the middle of the 19th century, wooden posts were used replacing metal as the post material. But these wooden posts absorbed fluids and expanded, causing root fractures as a result metal was continued to be used as a post material. Further research has resulted in the invention of custom cast posts and non-metallic posts made of zirconium oxide and fiber reinforced composite resin. Maximum protection of the crown margin cement seals Pleasing esthetics when indicated High radiographic visibility Retrievability Biocompatibility.

POSTS & DRILLS:

A dowel or post is a rigid restorative material that is placed inside the prepared root canal of the tooth. An ideal post offers maximum protection to the root, has adequate retention within the root, provides maximum retention of the core and crown, has high radiographic visibility, is retrievable and biocompatible.

Posts can be classified as metallic and non-metallic posts. The metallic posts can be custom made by the process of casting or prefabricated. Non-metallic posts are the more esthetic alternatives usually composed of carbon fiber, zirconium oxide or fiber reinforced composite resin.

 Retention form of the post is determined by the following factors:

• Post length - longer the length of the post, better the retention.
• Post diameter – should not exceed 1/3^rd diameter of the root.
• Surface texture – serrated and roughened posts have greater retentive properties than non serrated ones.
• Luting agent – Resin cements, GIC and zinc phosphate exhibit better retention properties than other luting agents.

 The post should also be designed to have a proper resistance form, to withstand the occlusal and torsional forces it is subjected to.

 

CORE BUILD-UP MATERIALS:

The core build-up is done over the cemented post to compensate for the amount of tooth material lost. Traditionally amalgam and glass ionomer cement have been used as the materials of choice for core build up. Cast cores can also be made using metal, or ceramic bonded to zirconia dowels. The advent of composite materials dedicated for core build-up has been a major advancement in post endodontic restorations. It eliminates the necessity of grooves or slots that have to be placed in amalgam cores for retention of the crown. They are available in dual-cure and light-cure variants and the possibility of shade matching makes the restoration highly esthetic.

 The following are a few desirable features of core build-up materials:

• Adequate compressive and flexural strength
• Biocompatibility
• Inhibition to dental caries
• Ability to bond to the tooth structure
• Resistance to leakage of oral fluids
• Dimensional stability

 

PEESO REAMERS:

Post space preparation is the first step in a post endodontic restoration requiring a post and core build up. Peeso reamers are used in removal of the gutta percha filling in the root canal to create space for the post. They are stainless steel rotary instruments available in various sizes. Bulk removal of gutta percha is possible with peeso reamers.

While preparing the post space, care should be taken to prevent any damage to the tooth structure. There should be a minimum of 1 mm of sound dentin around the post. An apical seal of 5mm is essential while preparing space for the post. Any unsupported dentin is removed using the peeso reamers to increase resistance form.
