Journal of Periodontology December 1992, Vol. 63, No. 12, Pages 995-996 About the author PhilipPettemerides BDS DPDS Dip Imp Dent graduated from the University of Sheffield in 1976 and is the principal dentist at Edgar Buildings Dental Care in Bath. His many member- ships include Executive Committee Member of the British Academy of Aesthetic Dentistry. Philip achieved the Certificate, Advanced Certificate and Diploma in Implant dentistry with distinction from the UCL Eastman Dental Institute, and trained in the All-on-4TM under the guidance of the concept’s founder, Paulo Malo, in Lis- bon. He has published several articles in scientific journals and frequently lectured for Nobel Biocare, where he is currently the lead presenter for The Nobel Biocare Procera Roadshow. the head of the implant was exposed on the labial aspect and this surface covered with Bio-Oss and BioGide resorb- able membrane. No relieving or periosteal relieving inci- sions were required to achieve complete tension free primary closure. The resin bonded bridge was re-cemented using a resin reinforced glass ionomer ce- ment to achieve ease of de-ce- mentation at the subsequent prosthetic appointments. After an integration period of four months, second stage surgery using a simple crestal incision allowed placement of a healing abutment ensuring minimal pressure on the peri- implant tissues. A closed tray impression technique followed (Fig 7) with delivery of a Zirconia screw-retained crown three weeks later. The Nobel- Procera CAD-CAM technique was employed whereby our laboratory, Fusion Dental in Newbury designed the frame- work, scanned the resin tem- plate and forwarded this to the Nobel Biocare facility in Stockholm. The feldspathic ceramic was built up expertly by Eva Forst directly onto the Zirconia. This material gives good biocompatible results and excellent aesthetics (Fig 8). The screw access hole can be almost invisible with matching composite resins. The use of ceramo-metal res- torations can be an aesthetic issue with mandibular resto- rations when it can be difficult to mask the metal of the screw access hole. A balanced aesthetic result was achieved with a gingival zenith matching that of the contra lateral tooth. Colour and texture of the peri-im- plant gingival tissues was con- sidered good although further maturation of the labial tissue is expected to occur. There was a slight loss of mesial papilla pre im- plant placement but due to good interdental crestal bone levels (Fig 9) on the adjacent teeth, I expect full papillary infilling to be restored within the next six months as per Dennis Tarnow’s study.3 The patient and her parents were pleased with both the functional and aes- thetic result. I feel we have achieved a good result very simply, using the latest offering from Nobel Biocare, based on sound biomechanical prin- ciples and bio-compatible materials. DT Fig 9
