A tube guide requires the drill be stacked above the tube, in line with the tube, adding 7-9 mm of height requirement to a case. Unfortunately, most of us don’t consistently measure the maximum inner incisal opening of our patients as part of our pre-surgical plan. And how many of us have had situations where this issue is not appreciated until the surgical appointment, in which case the tube guide is discarded.
We advocate measuring the patient’s vertical opening as part of the pre-surgical workup because this dictates whether or not surgery can be done. If it can be done, this dictates the length of your drill and the maximum length of the implant that you can use. This varies with different drill systems and the size of your hand piece.
ThinLayer™ Guides address the vertical space issue through its design, as it requires no more vertical space than freehand drilling. The first step is to insert a lance/spear or starter drill through a snug-fitting, disposable drill stop, part of a custom-made set for all drills in a sequence. This creates a bleeding point in the planned insertion location. After verifying you like the position, the drill is inserted through the guide further to create a pilot hole. Inserting the drill through the guide hole at an angle does not require any more vertical clearance than freehand drilling. If the drill and hand piece fit in the mouth without a guide, then it will fit with the ThinLayer™ Guide. Drag the tip of the drill along the gingiva, insert it into the pilot hole, and drill to depth. This procedure is then repeated with drills of increasingly large diameters.
We have constructed a chart you can use to see whether your drills and hand piece can be used in the case, which can be found at www.guidedsurgerysolutions.com/portfolio/vertical-space/.
