CAMLOG ROOT-LINE 2 Surgical Procedure

11 CAMLOG ® ROOT-LINE 2 IMPLANT Initial situation Abutments in lab analogs Prepared abutments Cement-retained bridge Development of a uniform insertion direction for the crown block should be part of the abutment preparation. The implant-abutment connection should not be altered. REMOVABLE RESTORATIONS A hybrid denture may be implant-retained mucosa-supported, or implant- supported. The tension-free seat of a secondary (double crown) or primary (bar-) splinted structure on implants is called “passive fit”. In the case of double crowns, this is obtained through intraoral bonding of the secondary crowns (preferably galvano crowns) onto the tertiary frame- work. In the case of bar structures, it involves the use of bar sleeves for a passive fit and intraoral bonding of the titanium bonding base. The idea is to create a fit that is free from stress or to minimize stress on the implants. When planning a removable denture, the implants should be placed so that, if necessary, an extension to a fixed restoration is possible. DOUBLE CROWNS The production precision of the CAMLOG connection is particularly neces- sary with double crowns restoration since the abutments can be fastened always in the same, exactly defined position on the implant. A precision fit for the removable superstructure is made simple and consistent in every case. Indication: The double crown technique is suitable for jaw relations in Angle Classes I and III. PLANNING INTRODUCTION Modern implant prosthetics is planned by working back from the desired therapy goal; this is referred to as “backward planning”. It applies particu- larly to pre-implantation augmentation procedures to restore sufficient bony structure to allow placement of implants in the optimal prosthetic position. Esthetics, function, phonetics, and hygienic potential require prosthetically oriented implant positioning and dimensioning, which the dental technician defines on the basis of the wax-up. The prosthetic design and the required implant position(s) and axial alignment(s) are planned by the dentist and dental technician working closely together. This requires both to be fully in- formed of the treatment options.
