CASE REPORT Simplistic Partially Limiting Surgical Guide for Flapless Implant Placement: A Case Report Aditi Nanda, MDS1* Veen Jain, MDS2 The accurate positioning of implant in bone is important in order to meet the biological, esthetic, and biomechanical requirements of the prosthesis. This becomes crucial in flapless implant placement. The combination of bone sounding and use of a surgical guide will allow precise placement of a dental implant, abutment, and provisional restoration in a minimally invasive manner. A technique to transfer the diagnostic information to the surgical guide is described in this report. The chief advantage of the procedure is the ability to apply flapless implant placement surgery and immediate loading. Key Words: implant, surgical, guide INTRODUCTION etermining the correct positioning of an implant in the bone to prevent encroachment on vital structures and adjacent teeth and to enable a prosthetic restoration that meets biological, esthetic, and biomechanical requirements is a challenge.1 The challenge is increased with the ‘‘blind’’ procedure of flapless implant placement because the different angulations of the drills may perforate the cortical plates, especially on the lingual surface in the mandibular molar area and the anterior maxilla.2 Bone sounding has been used in clinical dentistry to determine the thickness of the soft tissue overlying the bone and available bone volume.3 This provides the clinician with reliable information and a small margin of safety. Many types of surgical guides have been proposed to achieve correct implant placement.1,4 Information acquired in the preoperative planning phase is transferred to the surgical guide. Design concepts vary from simple nonlimiting, to partially limiting, and, finally, to completely limiting surgical Department of Prosthodontics, Maulana Aza Institute of Dental Sciences, New Delhi, Delhi, India. 2 Department of Prosthodontics, All India Institute of Medical Sciences, New Delhi, Delhi, India. * Corresponding author, e-mail: aditinanda@yahoo.com DOI: 10.1563/AAID-JOI-D-10-00123 1 D guides. The nonlimiting design, in general, provides the surgeon with an indication as to where the proposed prosthesis is located in relation to the selected implant site. The partially limiting design offers the possibility of having a guide sleeve direct the first drill used for the osteotomy. The remainder of the osteotomy and implant placement is then finished freehand by the surgeon. The completely limiting design restricts all of the instruments used for the osteotomy in the buccolingual and mesiodistal plane. As the surgical guides become more restrictive, less of the decision making and subsequent surgical execution is done intraoperatively.1 However, fabricating completely limiting guides may require advanced software (image-guided implantology5), may be expensive, or may require specialized training not amenable to all clinicians. Careful implementation of treatment plan will produce quality results even with partially limiting designs. This combination of bone sounding and use of a surgical guide will allow precise placement of a dental implant, abutment, and provisional restoration in a minimally invasive manner. A technique to transfer the diagnostic information to the surgical guide is described in this report.
