Bilaminar dual-purpose stent for placement of dental implants

Surgical templates for dental implant positioning; current knowledge and clinical perspectives

Dental implants have been used in a variety of different forms for many years. Since the mid-20^th century, there has been an increase in interest in the implant process for the replacement of missing teeth. Branemark was one of the initial pioneers who applied scientifically based research techniques to develop an endosseous implant that forms an immobile connection with bone. The need for a dental implant to completely address multiple physical and biological factors imposes tremendous constraints on the surgical and handling protocol. Metallic dental implants have been successfully used for decades, but they have serious shortcomings related to their bony union and the fact that their mechanical properties do not match those of bone. However, anatomic limitation and restorative demands encourage the surgeon to gain precision in planning and surgical positioning of dental implants. Ideal placement of the implant facilitates the establishment of favorable forces on the implants and the prosthetic component as well as ensures an aesthetic outcome. Therefore, it is advisable to establish a logical continuity between the planned restoration and the surgical phases, it is essential to use a transfer device that for sure increases the predictability of success. The surgical guide template is fabricated by a dental technician after the presurgical restorative appointments that primarily include determination of occlusal scheme and implant angulations. Here, authors genuinely attempted to review the evolution and clinical applicability of surgical templates used in the placement of dental implants.

Types of Implant Surgical Guides in Dentistry: A Review

Various techniques have been proposed for the fabrication of surgical guide templates in implant dentistry. The objective of this paper is to review the associated literature and recent advancements in this field, based on design concept. An electronic and hand search of the literature revealed 3 categories, namely, nonlimiting, partially limiting, and completely limiting design. Most clinicians still adopt the partially limiting design due to its cost-effectiveness and credibility. Moreover, clinicians use cross-sectional imaging during the preimplant assessment of surgical sites.

Role of surgical stents in determining the position of implants

AIM

Demand from implant patients for quality and efficient treatment is increasing. Fortunately dental implant treatment is evolving with patients expectations.

MATERIALS AND METHODS

The study comprised of 45 patients for whom 89 implants were placed at different sites. Efficacy of the stents is evaluated in determining the position and diameter of the implants.

CONCLUSION

this study shows the extreme accuracy of this surgical stents in implant installation in terms of position and diameter.

Computer-assisted implantology: historical background and potential outcomes-a review

BACKGROUND

The accurate transfer of preoperatively determined implant positions to the patient mouth is very beneficial to the dental practitioner as well as patients. The objective of this paper was to review the gradual development of computer-assisted implant surgery.

METHODS

All of the major data sources including unpublished data in the internet are considered

RESULTS AND CONCLUSIONS

Computer-assisted/-guided/-aided implantology has been founded to overcome the errors encountered during implant osteotomies and to position the implants more precisely. The protocols followed by this sophisticated technique are based upon the advocated concept of prosthetic-driven implantology and CT-scan analysis recently approved. Although several attempts have been made to improve this approach more and more, little has been done regarding the patient's demands, including cost. The inherent complexity of the techniques and materials utilized necessitates several degrees of training before attempting treatment and must be taken into account.

A dual-purpose guide for optimum placement of dental implants

Correct placement of implants is a requirement for implant treatment. The use of computed tomography and precise surgical guides is required when inadequate bone support is anticipated. This article describes the fabrication and use of an acrylic resin dual-purpose guide for radiographic evaluation of recipient sites and implant placement, which uses internally stacked stainless steel surgical guide channels. The drill guides are machined to allow consecutive surgical drills to be used without changing the implant angulation during surgery.

A surgical guide for accurate mesiodistal paralleling of implants in the posterior edentulous mandible

Malaligned implants often complicate the clinical and laboratory procedures employed for the fabrication of superstructures. Due to improper load distribution, an overall increase in stress concentrations on supporting implants may occur; in the long run, this may compromise the maintenance of the bone-implant interface. The utilization of surgical stents is imperative for optimum implant installation. This article describes a modified surgical stent that serves as a guide to proper mesiodistal paralleling of dental implants.
