title: Predictably replacing maxillary incisors with implants using 3-D planning and guided implant surgery.
abstract: Replacement of multiple adjacent teeth in the esthetic zone with dental implants is a surgical and restorative challenge, especially when an esthetic outcome is essential. Sound diagnosis and treatment planning can be combined with use of cone-beam computed tomography (CBCT) and 3-dimensional (3-D) software to achieve desired results. Placement of implants using guided surgical templates is critical when there is limited space between adjacent teeth or limited bone volume. Slight deviations in implant positioning during placement can lead to implants being too close to adjacent teeth, resulting in bone loss, recession, and encroachment upon adjacent papillae. Placement of implants in anatomically deficient or compromised areas is difficult when using a freehand drill protocol, because attaining the necessary precision cannot be achieved routinely. Esthetically demanding patients require precise implant placement. Use of guided surgical planning and implant placement enables the surgeon to take maximum advantage of available bone in anatomically restricted areas. Restoratively, ideal implant placement facilitates rehabilitation; therefore, all parameters must be observed in order to achieve an esthetically pleasing final restoration.
