A Novel Surgical Template Design in Staged Dental Implant Rehabilitations

Abstract

BackgroundThe philosophy of a gradual transition to an implant retained prosthesis in cases of full-mouth or extensive rehabilitation usually involves a staged treatment concept. In this therapeutic approach, the placement of implants may sometimes be divided into phases. During a subsequent surgical phase of treatment, the pre-existing implants can serve as anchors for the surgical template. Those modified surgical templates help in the precise transferring of restorative information into the surgical field and guide the optimal three-dimensional implant positioning.MethodsThis article highlights the rationale of implant-retained surgical templates and illustrates them through the presentation of two clinical cases. The templates are duplicates of the provisional restorations and are secured to the existing implants through the utilization of implant mounts.ResultsThis template design in such staged procedures provided stability in the surgical field and enhanced the accuracy in implant positioning based upon the planned restoration, thus ensuring predictable treatment outcomes.ConclusionsSuccessful rehabilitation lies in the correct sequence of surgical and prosthetic procedures. Whenever a staged approach of implant placement is planned, the clinician can effectively use the initially placed implants as anchors for the surgical template during the second phase of implant surgery.

Elaboración de un nuevo tipo de guías quirúrgicas para implantes dentales mediante impresión 3D

“…En las guías se pueden realizar algunas modificaciones como la eliminación de la porción vestibular o lingual / palatino de la zona de la preparación (guías de rielera) para mejorar la visibilidad, garantizar el paralelismo y disminuir la temperatura intraósea durante la preparación al disminuir la fricción y mejorar la irrigación (Akça, Iplikçioǧlu, y Çehreli, 2002); o la incorporación de pines de paralelismo para orientar el posicionamiento de la fresa durante el procedimiento quirúrgico (Patras, Martin, y Sykaras, 2012).…”

Drill bit guiding system for implant placement

“…A surgical stent is a template which not only assists in diagnosis and treatment planning but also facilitates in proper positioning and angulation of the implant in the bone. [12] A dual-purpose stent is a template that carries both clinical and radiographic information of the fixture angulation and location, and transferring the information from the surgical template or stent leading to successful implant placement. [3] The conventional surgical stents use a ring system to guide the pilot drill; only the computer-aided design (CAD) printed stents provide the guide sleeves for the sequential drill for implant placement.…”
