Extraction Sockets Literature 1 J ung RE, Philipp A, Annen BM, Signorelli L, Thoma DS, Hämmerle CHF, Attin T, Schmidlin P (2013) Radiographic evaluation of different techniques for ridge preservation after tooth extraction: a randomized controlled clinical trial. J Clin Periodontol; 40: 90–98. Source of supply for special materials > Implant: Straumann Bone level Regular CrossFit SLActive Fig. 18 Ten weeks after implant placement, spontaneous exposure of the healing cap was observed. This was not an ideal occurrence, however the premature exposure of the healing abutment did not result in significant recession of the soft tissues on the facial site. Fig. 19 The patient then returned to the prosthodontist, who constructed a provisional implant restoration to begin modifying the transmucosal emergence contour and to allow further maturation of the soft tissues. > Suture material: 5/0 chromic gut; Ethicon, Australia Fig. 20 Eight months after initial extraction and grafting, the definitive implant prosthesis was delivered. > Medication:  Antibiotic prophylaxis 3 g amoxicillin taken orally one hour before the surgical procedure, followed by 1.5 g amoxicillin daily in 3 divided doses for 5 days. Concurrently, twice daily rinsing with chlorhexidine digluconate (0.2 %) > Biomaterials: Geistlich Bio-Oss® Collagen (100 mg), Geistlich Mucograft® Seal (8 mm diameter), Geistlich Bio-Oss® 0.5 g (0.25 mm–1 mm), Geistlich Bio-Gide® 25 x 25 mm Contact > Dr. Stephen Chen, 223 Whitehorse Road, Balwyn VIC 3103, Melbourne, Australia. Telephone: + 61 3 9817 6055, e-mail: Acknowledgements Fig. 21 A lateral view of the implant prosthesis confirmed the ideal emergence profile on the facial aspect (8 months post-extraction). Fig. 22 An occlusal view of the 21 implant demonstrated excellent reconstruction of the facial contour of the ridge (8 months post-extraction). Treatment Concept of Dr. Stephen Chen, University of Melbourne and Private Practice, Melbourne, Australia Fig. 23 Anterior view of the final restoration during full smile (8 months post-extraction). Special thanks to Dr. Anthony Dickinson, prosthodontist in Melbourne, who managed the restorative treatment.

Fig. 25 The long-term CBCT control shows an optimal facial wall of approximately 2 mm thickness 2 years post-extraction or 18 months after commencement of restorative procedures. Fig. 26 An occlusal view 2 years after extraction, shows a stable emergence profile and an aesthetic result. 1.
