Universal Guided Surgery Drill Kit Mistral v.3 and Master SleevesPlace an order
The Mistral v.3 surgical kit has been developed with the aim to reduce the number of drilling components and optimize the workflow for the surgeon during an implant placement procedure.
The Mistral v.3 is reusable medical device intended for temporary use in the oral cavity. The kit provides the simplified step-drill protocol and supports a logical and easy to use work process for the specialist.
The ImplaStation libraries include digital components of the Mistral v.3 surgical kit which allows performing planning of the full sequence drilling with depth and width control for all implant system.
Distinctive features of the concept
- Compactness and simplicity
Mistral v.3 is a 6-piece compact set of instrumentation, specifically designed for a Shorter Drilling Sequence. Depending on bone density, the drilling sequence can range from 2 to 4 drills.
- Stabilized Drilling
Initial Drill is stabilized by the sleeve before drilling. After the initial cortical bone drilling, the next drill in the sequence is further stabilized by the osteotomy first and then by the sleeve. The Initial Drill is also designed to smooth the sharp ridge of the bone.
The dimensions of each drill have been designed to fit the parameters of most implant systems. Thus, it is possible in part or in full, to use the Mistral v.3 kit instead of the original surgical kit.
Ergonomically and carefully designed autoclavable box and tray.
- Innovative Master Sleeves
The Mistral v.3 Click sleeves are made of PEEK Medical Grade material, which provides high drill stability during a procedure. The outer size of the sleeve is 5.46mm, it should be used for interdental spaces from 5.6 mm and more.
The increased sleeve height (6mm) reduces the angular deviations of the drill by 20% compared to the most common 4-5mm sleeves. The smart design of the Mistral v.3 Click sleeves allows to "snap" it into the guide, escaping bonding step. Also, if necessary, during the procedure, the sleeve can be easily removed from the surgical guide. Mistral sleeves are autoclavable.
Digital implant planning procedure with Mistral v.3 surgical kit using ImplaStation software
There is a concept, which software uses to calculate a position of every single element such as an implant, drill and sleeve. The general idea of the concept is the implant is the primary object. The drill tip is connected to the implant apex and occlusal surface of the length we change the sleeve position, increasing and decreasing sleeve is connected with a drill stopper surface. And if we change the drill sleeve offset. There are two more instruments to change the drilling protocol. The first one is a drilling v-factor. When we increase v-factor drill's tip shifts down from the implant apex. The second one is the Drill Spacer. The Mistral v.3 includes two types of the Drill Spacer - one and two-millimeter plastic spacer. During digital implant planning we able to add the spacer and change a position of the sleeve and decrease the sleeve offset.
Drill selection should be made under the following guidelines
- After virtual implant placement the next step of the surgical protocol creation is a placement of the finishing drill. The finishing drill diameter depends on the implant diameter and the bone density. There is a recommendation for drill diameter related to bone density. For Bone Mineral Density 1 (D1) (Hounsfield Units HU>1250) the diameter of the drill should be equal or a bit less the implant diameter. For D2-D3 (HU 500-850) the diameter of the drill should be 0.3 mm less the implant diameter at least. For D4 (HU 350), the recommended diameter of the drill should be 0.5 mm less than the implant diameter.
- Next, there is a need to evaluate the position of the sleeve and offset.If it's necessary to move the sleeve coronal and increase the offset, for this in the line “Quick selection” change the Finishing Drill to a longer one. If it is necessary to move the sleeve apical and reduce the offset, in the “Spacer” line set up the required value multiple of 1mm to add spacer.
- After correction of the sleeve position, press button “Add to Drill list”. In this case, the position of the sleeve is blocked, and information about the selected finishing drill is transferred to the “Drill List” window.
- Then in the line “Quick selection” we need to select the initial cortical cutter (2.3x18 mm) and add it to the “Drill List”. If necessary, we can add a spacer to reduce the depth of drilling.
General surgical protocol recommendations
- As a rule, initial drilling is performed with an Initial Drill, which sets the correct direction for the subsequent preparation and, if necessary, smoothes the sharp bone ridge.
- The second drilling is done with a Finishing Drill to the depth specified in the surgical protocol.
- To ensure improved preparation accuracy, Intermediate Drills can be used. The drills are used from shorter and wider to longer and narrower. It is important to take into account that the diameter of the selected drills does not exceed the diameter of the implant in its different parts - from occlusive to apical.
- For finishing preparation, especially at Bone Mineral Density 1 (D1), the use of surgical and other tools specified by the manufacturer of implants is recommended.
- Drilling should be done according to generally accepted recommendations for bone preparation. The pressure on the tip should be minimal, with adequate irrigation. Unlike Free Hand implantation, the guided preparation of the bone is provided by the guide sleeve. In the case of work at a sharp bone ridge, it is necessary to pre-smooth it, in order to avoid drill slide off at the side surface.
