CAMLOG ROOT-LINE 2 Surgical Procedure

13 CAMLOG ® ROOT-LINE 2 IMPLANT REMOTE X-RAY SIDE VIEW Use for large sagittal differences and planned bone removal in the chin region. COMPUTER-TOMOGRAPHIC SCAN/DIGITAL VOLUME TOMOGRAPHY The CT/DVT is used for extensive radiological diagnostics and for generat- ing raw data for computer-based augmentation and implant planning. It enables a 3-D evaluation of the site from its anatomical structures and can provide information about the density of the existing bone (with DVT rela- tive only or via calibration). Indications must be strictly adhered to due to the increased radiation expo- sure compared to purely two-dimensional procedures. LABORATORY CAST ANALYSES It is essential to mount diagnostic casts in an adjustable articulator to assess jaw relations. Specifically, a check should be made whether a change of the occlusal position is worthwhile or required. If at all possible, it should be done before the actual implant-supported prosthetic treatment gets un- der way. In any case, a change in occlusal height must be preceded by treat- ment with a long-term provisional. DIAGNOSTIC CASTS The diagnostic casts must clearly show not only the occlusal surfaces but also the vestibular fold and retromolar areas. The centric registration must be freely adjustable to enable the casts to be mounted in correct axial alignment and position. The impression should reproduce the soft-tissue situation and any hard- or soft-tissue deficits as far as the vestibular fold, since it is here we detect the first indications to incline the implant or the necessity for bone augmenta- tion. Just as in perioprosthetics, the retromolar areas must be reproduced to allow specification of the dental arch and assessment of the vertical space available. Planning and implementation of periodontal implant-supported rehabilita- tion is much simpler when templates are used. ARTICULATOR SET-UP Diagnostic casts for implant planning are made of super-hard dental stone, just as in perioprosthetics, and mounted on an adjustable articulator with an arbitrary face bow and centrics registration. OCCLUSAL HEIGHT If an occlusal height requires correction, this must be done with a splint therapy or long-term provisional before the implant-supported prosthetic restoration begins. ARCH RELATIONS (TRANSVERSAL) The arch relations control the load direction and therefore the axial align- ment of the implants. This is particularly important with cross-bite situa- tions. ARCH RELATIONS (SAGITTAL) Crowns cannot be placed precisely over the implants in the presence of Angle Class II dentition because the soft tissues must be supported and the space for the tongue must not be reduced. A removable denture is indicated in this situation. INITIAL PROSTHETIC SITUATION The initial prosthetic situation describes the dental status, arch relations, the anatomical status of the hard tissue, the intraoral and extraoral soft tissue. The presence of functional, phonetic and esthetic restrictions can have influence on the patient’s quality of life.
