ABSTRACT

Objectives: Evaluation Of The Accuracy Of Dental Implant Placement Using Keyless Sleeveless Stererlithographic Surgical Stent. Methodology: The Study Was Designed As A Single Armed Clinical Trial. Ten Endosseous Tapered Implants Were Placed Using Keyless, Sleeveless Stereolithographic Surgical Stents. Postoperative Cone Beam Computed Tomography Was Taken And Superimposed On The Preoperative Virtual Plan To Assess Angular, Horizontal And Vertical Deviations.

Results: Results Showed That Implants Placed With Keyless Sleeveless Surgical Guide Had A Range Of Horizontal Deviation At The Coronal Side (C) Of The Implant Of 0.7-1.9 Mm With An Average Of 1.16 � 0.4 Mm. Horizontal Deviations At The Apex Of The Implants (Ap) Had A Range Of 0.2-1.46 With An Average Of 0.82 � 0.43 Mm. Vertical Deviations Of The Implants (V) Had A Range Of 0.1- 1.1mm With An Average Of 0.562� 0.34 Mm. Angular Deviations Between The Long Axis Of The Actual Implants To The Virtual Implants (A) Had A Range Of 0.51- 6.52 Degrees With An Average Of 2.7� 1.95 Degrees.

Conclusions: The Use Of Keyless Sleeveless Stereolithographic Surgical Stents Is A Reliable Method For Transferring Virtual Implant Placement To The Operating Field. Key Words: Dental Implants, Keyless, Sleeveless, Surgical Stents
