Surgical Guide Template

The coordination of the surgical and prosthetic ~edures through proper treatment planning is one of the most critical factors in obtaining an ideal esthetic: and functional result for the implant restoration. The surgical
guide template is a critical factor for implants placed in an esthetic area, because even slight variations of angulation can have large effects on the appearance of the final restoration. The construction of the surgical guide tem~ plate is-nearly indispensable for those patients for whom it is necessary to optimize implant placement to ensure correct emergence profiles in the anterior esthetic zone. The four objectives of using a surgical template for the. partially -edentulous patient are as follows: (1) delineate
embrasure, (2) locate implant within tooth contour, (3) r: ‘align implants with long axis of completed restoration and (4) identify level of cement.oenamal [unction (eEl) or tooth emergence from the soft tissue (Fig. 1440). The . ‘. template most useful in the anterior esthetic zone is a
dear resin te mplate, which allows a surgeon ease ofaccess to the bone and uninterrupted visual confirmation of frontal and sagittal angulations (Fig. 14-41). The. surgeon stays as close as’ possible to the template during
implant placement (Fig. 14-42). The ultimate result should allow the surgeon to place the implant optimally in bone while maintaining the amgulatton that will provide the least compromise of the ‘final restoration .

In posterior edentulous areas, a similar template is fabricated  with directional holes drilled through the template.  This surgical template provides the surgeon with a guide to locate the implant placement accurately .and direct the long-access inclination of the implant (see Fig. 14-40). The surgical template for’ the completely edentulous mandible should allow the surgeon maximal flexibility to select the implant position In UeJesorbed bone but yet provide guidance as to the angulitibn  equirements of the .
