CAMLOG SCREW-LINE Surgical procedure

8 CAMLOG ® SCREW-LINE IMPLANT Esthetically challenging region To achieve an esthetically successful estoration, a number of important ele- ments are required: a harmonious gingiva line, optimal implant positioning as well as vertical/orofacial and mesio-distal dimensions, a physiological crown shape, and the presence of interdental papillae. The indications for the hard-tissue configurations to be preserved and for soft-tissue ma- nagement must be observed during planning. Implant diameters and lengths must be sized properly to leave adequate bone (at least 1 mm) around the implant. Maintain a minimum distance of 1.5 mm to an adjacent natural tooth and 3 mm to an adjacent implant. Structure-preserving or structure-sparing procedures must be used during flap creation and implant placement. In addition, oral hygiene require- ments must be kept in mind during planning. Mesio-distal implant position at bone level Distances at bone level IMPLANT POSITION PLANNING Splinted crowns In the event of unfavorable leverage relations around the implant, a choice must be made between a longer implant or, if this is anatomically impossi- ble, splinting adjacent crowns. If splinting is required by reason of stability, then hygienic requirements must also be taken into account. Development of a uniform insertion direction for the crown block must be part of the abutment preparation. The implant-to-abutment connection should not be altered.
