Richard (photograph 1 till 16) Richard had lost the 12 element on which a rootpost and a crown was made because of a broken root. Directly after extraction a 5 mm broad and 13 mm long zirconium implant was placed. A temporary bridge was made directly on the 11 element with a dummy for the 12 element. The first photograph has been made two weeks after the implant insertion. The implant has been placed on gingiva level. The cavity for the glass fibre pins was closed with Fuji-cement and filled with Ca(OH_). After a healing period of six months we continued with the preparation of the glass fibre abutment pins in the same way as we do with natural elements. First of all the space for the pins is cleaned and after that covered with etch and primer for the cementation with Panavia. Afterwards the pins are placed and composite is brought around the pins. After hardening the preparation can be made, simply according to the principles of a round shoulder crown preparation.
At this stage we where very satisfied to work with Michel Magne. He has much interest in the aesthetic possibilities of zirconium implants. It was also a very interesting experience to work with a dental technician who works 6000 km away from our dental practice (Magne has a dental laboratory in Los Angeles, USA), and we used Internet, digital photographs and chatting for planning the final result. First of all we fitted the crowns in biscuit,then moisturized them with a special gas liquid, and photographs were taken. The crown on the implant looks more nicely than the one on the natural element which is darker into the root due to the canal treatment and the golden rootpost. The shape chosen by Michel matches surprisingly well with the natural elements: a very natural unit. Both palatinal and labial the implant with the crown looks fantastic. With many thanks to Michel Magne.
1. Acrylic cantileverbridge on 11 and 12, a small edge of the implant is visible on the 12. 2. A buildup out of gold on the 11, the top of the zirconium implant on the 12. 3. X-ray of the zirconium implant. 4. Glass fibre pins with compositecement placed in the middle of the implant. 5. Preparation of the glass fibre pins and the outline of the implant. 6. X-ray of the implant with the acrylic buildup, no loss of bone around the implant, it supports the bone just like a natural element.

7. Preparation is ready for the impression. The outline in the biological zone, a retractioncord in the sulcus. The 11 is etched for a coating on the buildup and the stump. 8. The coating on the 11 is ready as well as the preparation of the 12. Garland shape of the gingiva,no loss of supporting tissue around the implant. The sulcus is like a natural tooth, no abutment , no artificial pocket. 9. Incisal view, buccally nice support of the implant, no loss of bone, natural outline. 10. Temporary crowns on the 12 and 11. 11. Michel Magnes’crowns in biscuit on the plastermodel, papillas unchanged and gingiva to surround the implants. 12. Dry fitting in biscuit, check of the margin, magnificent connection with the implant, no discoloration of the outline, the 11 stays a little darker in the gingiva. 13. Moisturizing of the biscuitcrowns with special fittingliquid to judge the colour. 14. Palatinal view; nice shape, splendid incisal shape and colour. 15. Finally; Beautiful piece of work of Michel Magne, the 12 is unrecognizable as a crown on an implant, pocketdepth 2 to 3mm. 16. X-ray of the final result, stabile bone, beautiful connection of the porcelain.
