Use of transitional implants to support a surgical guide: Enhancing the accuracy of implant placement

Flapless implant surgery in the edentulous jaw based on three fixed intraoral reference points and image‐guided surgical templates: accuracy in human cadavers

“…In the NobelGuide concept (Nobel Biocare, Gothenborg, Sweden), the interocclusal index is used to position the surgical template in the same position during surgery and three template‐guided horizontal stabilizing pins, located in between the planned implants, are anchored to the bone during occlusion (van Steenberghe et al 2002; Sanna et al 2007). In the SurgiGuide system (Materialise Medical Inc., Leuven, Belgium) and the DADImplant system (DAD Implant, Medfield, MA, USA), the template is similarly fixed to the underlying bone via three mini screws (Simon 2002; Fortin et al 2003). However, accuracy data comparing stabilized with non‐stabilized mucosa‐supported surgical templates have not been published so far.…”

A Novel Surgical Template Design in Staged Dental Implant Rehabilitations

“…Even though several techniques have been reported in the literature for surgical template stabilization in the form of surgical fixation screws [17], transitional implants [16,18,19], or sequential extraction of the remaining teeth during implant placement [20], those solutions seem to be rather complicated. Therefore, whenever a staged rehabilitation is planned, the clinician can effectively use the existing implants as anchors for the surgical template during the second phase of implant surgery.…”

The Role of the Template in Prosthetically Guided Implantology

“…In the past, implant site and inclination were dictated by residual bone quantity. The desire for a predictable prosthesis, 1–2 particularly for fixed partial dentures, led to the development of a new concept of “prosthetically guided implantology.” This concept establishes the correct implant position during the diagnostic stage according to the planned definitive restoration 1–7 …”

“…In edentulous patients, the reflection of the mucoperiosteal flap changes the fit of the template base on the underlying tissues. For instance, for the maxilla, the template needs a suitable palatal support with extensions to the tuberosities, while for the mandible, the ideal solution is a tripod supported by two posterior flanges resting on both retromolar pads and by an anterior extension, measuring a few millimeters in width, in the symphysis region 7 …”

“…This concept establishes the correct implant position during the diagnostic stage according to the planned definitive restoration. [1][2][3][4][5][6][7] To identify the implant site according to the habitual occlusion, the static, functional, and dynamic relationship of the occlusal condition is analyzed. Information about the ideal loading axis, gathered from diagnostic/study mounted casts and a diagnostic wax-up, is transferred during treatment planning to the radiographic/surgical template.…”
