Fig. 4_ After removing the temporary crowns on teeth 12 and 21, the supra-alveolar periodontal attachment of tooth 11 was severed with a periotome. Fig. 5_The root was extracted after atraumatic removal of the crown. The buccal bone lamella connected to the root surface was lost during the process. Fig. 6_The palatal margin of the alveolus was marked with the pilot drill through a deep-drawn guide prepared in the laboratory. Fig. 7_When inserting the implant, the surgeon oriented himself along the palatal bone wall. Fig. 8_The implant was palatally displaced in the correct position; the buccal bone lamella no longer existed. Fig. 9_The position of the implant in the dental arch was checked with the aid of the guide. Fig. 10_ A retromolar bone cylinder was harvested with a trephine drill to obtain autologous bone for augmentation of the buccal lamella. Fig. 11_The space between the implant and buccal soft tissue was filled with a mixture of autologous bone and bovine bone replacement material. Fig. 12_ In order to obtain optimal buccal contours, a connective-tissue graft harvested from the palate was drawn under the soft tissue and sutured. Fig. 13_The temporary bridge was cemented with the healing cap without contact with the pontic. Fig. 14_The sub-crestal bone position and good cervical join of the temporary bridge are shown on the post-operative X-ray. Fig. 15_Good healing and successful integration of the connective-tissue graft are evident one week after immediate implantation. The white-yellow deposits are fibrin.
