priti crown Your patients deserve you
3 and you deserve the priti crown So close to nature priti crown is a high-tech solution for making perfect crown and bridge restorations using state-of-the-art CAD/CAM technologies. priti crown for the first time ever, a three-dimensional veneered crown blank modeled on nature and suitable for making all-ceramic dental restorations is available. priti crown is the result of many years of research and development carried out for the benefit of you, the practitioner, and your patients. priti crown allows you to benefit from: Reliable, plannable, functional and highly esthetic restorations The peace of mind offered by using a ceramic material which has been tried and tested over a million times priti crown the logical extension to CAD/CAM technology

Benefits 5 Benefits... for you the dentist and your dental clinic: Plannable results Shorter treatment times Specifically coordinated treatment schedules Quality assurance and reproducibility Extremely safe and reliable material proven in long-term clinical application Best grinding and polishing properties for easy chairside finishing... for your patients: priti crowns live up to today s ideals of beauty Can be produced to a number of esthetic quality standards High-quality materials and manufacturing processes make the restorations reliable and safe Abrasive properties are similar to those of natural dentition no damage to opposing teeth
6 Material Nature is the benchmark During the development of priti crown, not only were esthetics, form and function firmly in the foreground, but the focus was also on material properties which resemble those of natural dentition. The properties of the material used are similar in terms of light dynamics, strength and abrasion characteristics to those of natural tooth substance. For this reason, each priti crown is made from the fine-grain feldspar ceramic, VITA Mark II, tried and tested over a million times. The fact that the VITA Mark II material is so close to nature has been proven time and again by studies carried out over a period of more than 20 years. Once cemented into place, the priti crown has abrasion values which are comparable to those of natural dental enamel. The material properties of the priti crown* are virtually identical to those of natural dentition.

Clinical studies 7 For over twenty years, studies have been documenting the long-term success of the material There are 25 million reasons for using this material, since this is the number of patients who have already been fitted with it. Thanks to its excellent material properties, it is extremely easy to grind and also polishes well. In a separate study by Bindl and Mörmann, molar crowns made from VITA Mark II showed a success rate of 97% over the duration of the three and a half year study. [...] Many studies show that the enamel abrasion when using restorations made from VITA Mark II with glazed or polished surfaces corresponds to the abrasion of enamel against enamel. [...] Using ceramics cemented with an adhesive enables the original strength of a tooth to be restored to up to 96%. The properties of the ceramic are very similar to those of natural enamel; the ceramic enamel/dentin complex emulates the structure of natural dentition. Giordano, R. A.

You can find further studies on the web site: SEM image of the surface (magnified 1,000 times), showing a polished surface on the left and after etching for 40 seconds on the right. The uniform and highly retentive etched pattern resulting from the homogeneous distribution of the crystal and glass phases can be clearly seen.
8 Indications Perfect restorations for many indications priti crown offers intelligent solutions Area of indication Restoration Cementation anterior crown adhesive self- adhesive posterior crown partial crown adhesive self- adhesive priti crown as a single-tooth restoration The anatomically contoured and three-dimensionally veneered priti crown is the ideal starting point for cemented single crowns in the anterior and posterior regions. The use of an industrially prefabricated crown blank minimizes the risk of chipping. Area of indication Restoration Cementation Anterior crown conventional bridge self- adhesive 3-4 units Posterior crown conventional bridge self- adhesive 3-4 units priti crown as a priti crown@on With priti crown@on restorations, the priti crown CAD/CAM monolithic veneer is bonded to a framework made from high-strength zirconia. The materials are bonded together by means of a highly stable and durable acrylic compound or a frit glass. These crowns and bridges are cemented in the usual way. priti crown for implants The priti crown is suitable for dental implants in all areas of indication.

10 Self-adhesive cementation 1 2 3 Before taking the impression, tooth 22 was fitted with a tooth-colored abutment. After manufacturing and checking the esthetics and fit of the priti crown, the tooth stump was cleaned and prepared for self-adhesive cementation. The priti crown was etched for 60 seconds with a 5% solution of hydrofluoric acid and then rinsed out well with water, dried and silanized with a suitable bonding agent.* The prepared tooth stump is first coated with a primer*, then the appropriate adhesive* is applied.
11 4 5 6 After the self-adhesive composite* has been applied, the crown is fitted onto the prepared tooth stump. The composite is briefly cured by light polymerization in order to make it easier to trim off the excess. The final priti crown immediately after insertion shows the excellent esthetic behavior in the oral cavity. The natural-looking result is achieved by precision machining perfected by finishing touches and skilled shading applied by a dental technician. Photos: Dr. med.dent.

12 priti crown@on 1 2 3 Because of the difference in size among the individual stumps and the partly non-vital remaining tooth substance, it was decided in this case to make priti crowns using the priti crown@on-technique. Four zirconia copings in the shade A3 form the basis of the priti crown@on-technique used here. Then four priti crowns were designed and ground using CAD technology to produce a perfect fit. The result after fitting and veneering the priti crowns. After cementing the priti crowns onto the zirconia copings, the margin areas are tapered and polished to a high luster.

A close-up taken after fabricating the restoration reveals the vibrant surface and shows that the natural curve of the incisal dentin is already present in the blank. The final result: The priti crown@on technique presents fascinating opportunities for many complex areas of application. Photos: Gernot Bartl, M.Sc.., dental surgeon, Wiesbaden
