Guide Right™ Implant Template Components
Guide Right™ is a precision implant placement technique designed and developed for prosthetic driven implant placement. Precision placement of implant fixtures is becoming increasingly important, as we understand the relationship of the direction which forces are applied (of the directional forces applied) to the implant and the life span of the implants. Ideally the center of and long axis of the implant should be located under the center of the vertical forces applied to the implant from the opposing dentition. Surgical templates help the surgeon to accomplish this. The Guide Right Surgical Template System consists of multiple components:

1) Guide Posts. Guide Right offers four different Guide Posts. All are made of stainless steel. Three diameters are available, 3 mm, 4 mm, and 5 mm.
The 3 mm Guide Post is available in straight, angled or offset configurations. It is used for the placement of the 3 mm Anterior Straight Cut Guide Sleeve and the Angle Cut Posterior 3 mm Guide Sleeve. The 4 mm Guide Post is available in either a standard or a magnetic version. The Magnetic Guide Post has a magnetic field. The Magnetic Guide Post attracts the Open Guide Sleeve and is used to hold the Open Guide Sleeve on the Guide Post while the template is being made. All of the Guide Posts feature a shaft with two different diameters. One larger end conforms to the inside diameter of the Guide Sleeve that is used to prepare the osteotomy site. The other end has a smaller 3/32nds outside diameter, the same size as a dental drill shaft used in a straight or laboratory hand piece. Some of the larger Guide Sleeves require fabrication inserts to allow the fabrication of the template. The fabrication insert is placed inside the Guide Sleeve to hold and centered it over the Guide Post while the template is being fabricated.

2) Guide Sleeves. Guide Sleeves are made with surgical stainless steel or ceramic material (Alumina). The metal sleeves work very well with periapical and panorex X-rays but are not recommended for use with cone beam X-ray machines. Ceramic Guide Sleeves do not produce the "X-ray scatter" that is associated with metal Guide Sleeves when using cone beam X-rays. Stainless steel Guide Sleeve components are offered in either straight cut or angled cut or with one side open for use in posterior areas where accessibility is very limited. The longer Straight Cut Guide Sleeve is used mainly for anterior areas where access is unlimited. The shorter Guide Sleeves can be used both in the anterior or posterior areas where precision is not as important as accessibility is. All of the Guide Sleeves have brackets or a boss with undercuts on the outside surface for attachment to the acrylic body of the template. The Open Guide Sleeves are designed for use in situations where the accessibility is very limited. The Open Faced Guide Sleeves allow the placement drills into the Guide Sleeve from the side when the patient can not open far enough. The Angle Cut Sleeves can be used for either posterior or anterior sites as can the Open Faced Guide Sleeve but they are not as accurate as the Straight Cut Guide Sleeve. The Guide Sleeves dictate the direction of the drill preparing the osteotomy. The Serial Guide Sleeve Sets and the Ceramic Guide Sleeves have inserts which fit inside of the outer sleeve which has the bracket for attachment to the acrylic body of the template.

• Implants in both groups were placed using a guide sleeve for the initial 2mm drill only.

• For Group A, additional drills were used freehand without guide sleeves:

Mean + - Standard Deviation
X-sectional view 6.7 degrees +- 3.9
Tangetal view 3.9 degrees +- 3.3
 

• For Group B, additional drills were used to enlarge the osteotomy with graduated guide sleeve inserts, increasing accuracy:

Mean +- Standard Deviation
X-sectional view 1.9 degrees +- 1.2
Tangetal view 1.9 degrees +- 0.9
 

The clinical results suggest the use of multiple graduated drill guide sleeve inserts to enlarge the osteotomy increases the accuracy of the planned axis of implant placement when compared to the use of a 2 mm guide sleeve for initial osteotomy only.
