Immediate implant placement combined with titanium granules - 4 years of clinical experience
The immediate implant placement in the esthetic zone is an often performed procedure (1, 2, 3, 4). The position of the implant is in direct contact to the palatal wall. There are different concepts for the management of the remaining gap between the implant and the buccal bone plate. The aim is to avoid the horizontal and vertical collapse of the alveolar crest.
Method and material:
In this study, the gap was filled up with white titanium granules (Tigran Technologies, Malmö, Sweden). 35 implants were placed in the region of the upper incisors, canines and of one bicuspid. After the placement, a healing abutment in the same diameter as the implant was connected. The granules were mixed with blood and pushed with gentle pressure into the gap. The healing abutment was removed and replaced by an abutment in a diameter corresponding to the replaced tooth. A temporary crown was fixed to the abutment and adhered to the adjacent teeth. After a healing time of 3 months, the abutments and temporary crowns were replaced by the definite reconstruction. To evaluate the stability of the alveolar process, clinical pictures were taken before extraction and after the delivery of the final crown. In addition measuring was made using the planning model and the master cast.
The healing period was uneventful in all cases. Some granules in the margin of the soft tissue were removed before the impression. The final restorations showed a healthy gingival margin and no discoloration of the soft tissue. All patients were satisfied with the clinical results. The minimal horizontal collapse of the alveolar process (0.0 to max. 1.1 mm) doesn´t compromise the clinical situation.
These early results justify further use for this indication.
