This is the same allceramic case seen in Figures 8 and 9. On the left is the original solid pour model. On the right is a revised solid model sent back by request to the doctor for re-prep. Note changes in shoulder width and overall reduction. Crowns, if fabricated over the preparations as originally cut, would have been bulky, unaesthetic, and prone to premature fracture. If this doctor had refused to re-prep according to all-ceramic guidelines, then a PFM would have been recommended. https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/62756708-f0a6-4fa3-9f8b-5d8680bab12c/2-Figure4-1.jpg Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 4.

Note the attempt to save a small portion of the cingulum areas on these maxillary central incisors. https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/938cb8a7-1edf-4f21-83b4-d5d6ac74c30e/3-Figure6-1.jpg Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 6. The usable width of a shoulder is reduced by tipping in the bur too far at the margin, creating an undercut. https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/c25d4d62-80af-437d-b91c-4676acef1b76/5-Figure13-1.jpg Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 13. With the doctor's permission, the dies were revised in the laboratory before sending them back as a guide for a patient re-prep using the same 379-023 football diamond (Brasseler) https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/573ecb9d-d693-4a9f-88dd-c9c58af781a4/Screenshot_9-12-2024_112244_.jpg Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 14.

The lingual view shows the unnatural contours that the technician had to create due to the location of the final lingual and interproximal margins. https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/fbaff3b9-ef91-4b92-b69a-dbfc56230ae9/Figure2 Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 2.

Compare these 2 photos and observe the relative axial inclination of the anterior teeth. This will present a severe structural and aesthetic dilemma for the dental technician who must try to accomplish the end result as outlined in the model of the diagnostic wax-up in Figure 10, utilizing the preparations in Figure 11. https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/ec834277-e86d-4000-9d58-18722a44020d/4-Figure7-1.jpg Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 7.

The same case as Figure 14 viewed from the lingual, showing the measured clearance at 0.1 to 0.3 mm. The doctor was informed, and reduction of the opposing mandibular anteriors was requested. This was strongly discouraged by the dental technician due to the amount of reduction needed. https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/3ae84797-7f1c-4951-ab8d-e4e35a3aebde/6-Figure17-1.jpg Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 17.

Compare these 2 photos. Figure 8 shows all-ceramic posterior preparations with what looks like "plenty of room." In Figure 9, a 1-mm Flexible Clearance Tab verifies that the occlusal reduction is far short of the 2 mm recommended for posterior all-ceramic crowns. https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/9b7a5d89-265c-410f-bdd2-dcc5bfa7195c/Figure+1 Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 1.

The facial view appears as if it will be aesthetically pleasing. (The die has also been blackened to help illustrate a potential aesthetic dilemma on the right central incisor. Depending on the underlying stump shade, failing to reduce in multiplanes will result in nonuniform porcelain coverage causing an aesthetic compromise or failure.) https://images.squarespace-cdn.com/content/v1/67471d2a6d9f1c71d2778663/646c51bd-7506-4841-bf14-6d9f147cc305/5-Figure12-1.jpg Resources - The Ten Most Common All-Ceramic Preparation Errors: A Doctor/Technician Liaison's Perspective - Figure 12.
