Radiographic Stents and Surgical Stents in Implant Placements: An Overview

Abstract

Aim: This article presents an overview about various simple techniques for fabrication of radiographic and surgical stents for implant placement. Background: Dental implantology is now a feasible option to conventional prosthodontics. A need for predictable prosthesis has resulted in the emergence of prosthetically guided implantology. A radiographic stent is used for evaluation and determination of the accurate position for implant placement during the planning and for identification of the accurate site for the placement of implants during the surgical procedure. Radiographic and surgical stents help in placement of the implants in a precise and predetermined position and angulation, along with minimizing unnecessary osteotomy, results in an accurate design of prosthesis, reducing the time for implant placement and trauma caused to the patients thus increasing their comfort. Conclusion: Using stents for implant placement helps achieve accurate position and angulation of implant.

The impact of surgical guide design and bone quality on heat generation during pilot implant site preparation: an in vitro study

“…Surgical guides have evolved to facilitate precise implant placement, by transferring the preoperative plan to the surgical field in a correct position that fulfils the functional and aesthetic requirements [ 5 , 6 ]. Surgical guides, either non-limiting or limiting, will restrict the flow of the cooling agent to the osteotomy site, which will lead to a temperature rise that provokes tissue injury if exceeding the maximum threshold [ 6 , 7 ]. Surgical guides they can be fabricated either manually [ 6 ], or with aid of CAD/CAM technology [ 6 , 7 ].…”

Surgical guides they can be fabricated either manually [ 6 ], or with aid of CAD/CAM technology [ 6 , 7 ]. Advances in patient imaging and planning allow guides to be constructed that limit the orientation of the twist drill to the required angle [ 8 ].…”

“…The different types and accuracy of surgical guides has been well reported in the literature [ 7 ]. These surgical guides, either non-limiting or limiting, will restrict the flow of the cooling agent to the osteotomy site, which will lead to a temperature rise that provokes tissue injury if exceeding the maximum threshold [ 6 ].…”

Assessment of prosthetic complications of customized and electrical welded frameworks in maxillary implant fixed detachable prosthesis (split mouth study)

“…1,2 The location number and distribution of the implants, the cost and time required to fabricate and maintain the prosthesis considered factors for selection between fixed and removable implantretained prostheses. 3,4 Fixed detachable prosthesis is defined as "A fixed dental prosthesis that replaces the entire dentition and accompanying structures of the maxillae or mandible; it cannot be removed by the patient. 5 it offers several advantages, preservation of the underlying bone compare to the conventional complete denture as it will be supported by multiple implants that allows favorable stress distribution, the characteristic of a fixed prosthesis and retrievable which improve patient satisfaction compared to removable options.…”
