MDL Insert - Intra-Lock

MDL ® Surgical Procedure
Overdenture Stabilization
The Mini Drive-Lock Surgical Kit organizes all instrumentation necessary for the procedure and features a
convenient stainless-steel tray that is easily removed and placed in the sterile operator field.
Light, repeated, intermediate, vertical introduction of the MDL ® 1.2mm Pilot Twist Drill breaches the gingival
tissue and periosteum (Fig. 1). Copious sterile saline irrigation is recommended (Fig. 2). Drilling depth is
approximately one third the length of the implant with care taken to breach the cortical plate (Fig. 3).
MDL ® ’s are packaged suspended on titanium rings specially engineered to facilitate a no-touch delivery and
placement utilizing Drive-Lock technology (Fig. 4). The MDL ® Contra-Angle Driver (MDLCAD) is engineered
to slip over the O-ball assembly, firmly engaging the implant for direct delivery and initial seating.
Use a slow speed high-torque handpiece (15 RPM or less) and the MDL ® Contra-Angle Driver to begin to
insert the MDL ® Implant (Fig. 5). MDL ® ’s sharp apical guiding point initiates self-tapping action; threading and
expanding the bone at the same time (Fig. 6). The use of an electric motor with a torque-limiting feature set
to 35Ncm is recommended. The Torque-Lock ® Torque Wrench can also be used to determine the implant’s
torque resistance.
When the torque limiter stalls the handpiece or the Torque-Lock ® registers
approximately 35Ncm, an MDL ® Ratchet Driver (MDLRD) with a Surgical
Ratchet Wrench (SRA) is used (Fig. 7). Small incremental turns; with a pause
between each turn takes advantage of bone’s viscoelastic nature (Fig. 8).
MDL ® Implant seating is accomplished when the Ratchet Driver is
flush with the surrounding gingival tissue (Fig. 9).
