CosmoPost – Basics ﬁrst

Make sure that… The following applications are absolutely

contraindicated:

… the length of the post within the canal at least corresponds to the coronal length of the clinical crown,

Using the 1.4-mm CosmoPost for the following teeth: FDI designation: 13, 11, 21,23, 33, 43 ADA designation: 6, 8, 9,11, 22, 27

… the CosmoPost is not provided with retention grooves under any circumstances,

… the impression post does not come into contact with the impression tray.

Application for patients with a deep overbite, bruxism or suspected bruxism.

If there is insufficient supergingival dental hard tissue.

The supergingival dental hard tissue must measure at least 2–3 mm. In other words, the preparation margin must be approx 2–3 mm below the build-up.

Contraindication

CosmoPost – Notes for dentists

and dental technicians

Indication

Since CosmoPost is a ceramic post system, the main indication is the aesthetically important anterior region, both in the maxilla and the mandible.

l Anterior region

– 1.4-mm CosmoPost

Use:

1. In the maxilla: only for the lateral incisors, ie, teeth 12 and 22 (FDI); teeth 7 and 10 (ADA).

2. In the mandible: for the central and lateral incisors, ie, teeth 32 to 42 (FDI); teeth 23 to 26 (ADA).

Any other application is contraindicated and may compromise the success of the prosthetic restoration.

– 1.7-mm CosmoPost

Use:

The 1.7-mm CosmoPost is used for those teeth, for which the diameter of the coronal part of the root or the coronal endodontium clinically indicates a 1.7-mm root canal post. These teeth are usually the four canines and the central incisors in the maxilla.

II Posterior region

– Depending on the clinical situation, both the 1.7-mm and

1.4-mm CosmoPost can be used in the posterior region. Generally, the 1.4-mm post is used for maxillary and mandibular premolars, while the 1.7-mm post is used for molars (distal canal in the mandible, palatal canal in the maxilla).

Important

– The indications and working parameters must be

observed at all times

– The CosmoPost must not be adjusted by grinding,

tapered, or provided with retention grooves, since such measures may result in predetermined breaking points on the post.

– The post must not be blasted with aluminium oxide

(Al

2O3

). The surface of the post has already been

roughened.

The use of the 1.4-mm CosmoPost is absolutely contraindicated for the marked teeth (FDI: 13, 11, 21, 23, 33,

43) (ADA: 6, 8, 9, 11, 22, 27).

Additional contraindications are as follows: – Use of the CosmoPost for patients suffering from bruxism

or suspected bruxism

– Deep overbite

Important

If the deﬁned preparation (residual dentin) is not possible or one of the above contraindications is present, a metal post must be used, since the risk of a post fracture is clearly increased. A fractured post most often results in the extraction of the root, since the post is virtually impossible to remove.

– Less than 2–3 mm supergingival dental hard tissue

– Circular isogingival damage – Allergy to any of the ingredients

Indication

Core build-up in combination with the CosmoPost (zirconium oxide root canal post).

Contraindication

– Neither metal alloys and metal-ceramics (eg IPS Classic,

IPS d.SIGN) nor all-ceramic layering materials (eg IPS Empress, IPS Empress 2, IPS Eris for E2) may be fused to the CosmoPost (root canal post).

– Conventional IPS Empress ingots cannot be used in

combination with the IPS Empress Cosmo Ingot.

– If patients are known to be allergic to any of the

ingredients, the IPS Empress Cosmo Ingot should not be used.
