LITERATURE REVIEW Types of Implant Surgical Guides in Dentistry: A Review Kathleen Manuela D’Souza, BDS* Meena Ajay Aras, MDS 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. Key Words: implant guidance, implant placement, surgical guide, surgical template, implant dentistry INTRODUCTION ecent studies on the clinical success of dental implants have indicated a high implant survival rate.1 Nevertheless, the inadvertent association of most surgical and prosthetic complications with improper diagnosis and implant placement has also been documented.2 These factors play a crucial role in the long-term predictability and success of implant prosthetics. Surgical guide templates not only assist in diagnosis and treatment planning but also facilitate proper positioning and angulation of the implants in the bone.3 Moreover, restorationdriven implant placement accomplished with a surgical guide template can decrease clinical and laboratory complications.4 Hence, increasing demand for dental implants has resulted in the development of newer and advanced techniques for the fabrication of these templates. DISCUSSION R (1) Nonlimiting design (2) Partially limiting design (3) Completely limiting design These design concepts are classified based on the amount of surgical restriction offered by the surgical guide templates. Nonlimiting Design Nonlimiting designs only provide an indication to the surgeon as to where the proposed prosthesis is in relation to the selected implant site.6 This design indicates the ideal location of the implants without any emphasis on the angulation of the drill, thus allowing too much flexibility in the final positioning of the implant. Blustein et al7 and Engelman et al8 described a technique in which a guide pin hole was drilled through a clear vacuum-formed matrix (Figure 1). This hole indicated the optimal position of the dental implant. However, the angulation was determined by the use of adjacent and opposing teeth. Almog et al9 described the circumference lead strip guide in which a lead strip was attached to the external surfaces of the diagnostic waxing. This was used to outline the tooth position over the implant site. It has been observed that the use of these guides may result in unacceptable placement of the access hole and/or unacceptable implant angulation. Hence, these templates can serve as imaging indicators during the surgical phase of implant placement. Journal of Oral Implantology 643 Surgical guide template fabrication involves a diagnostic tooth arrangement through one of the following ways: (1) a diagnostic waxing, (2) a trial denture teeth arrangement, or (3) the duplication of a preexisting dentition/restoration.5 The fabrication of the surgical guide templates is then based on one of the following design concepts6: Department of Prosthodontics, Goa Dental College and Hospital, Bambolim, Goa, India. * Corresponding author, e-mail: kath_dsouza@yahoo.co.in DOI: 10.1563/AAID-JOI-D-11-00018
