Preparing implant osteotomies: regular surgical micromotor vs physiodispenser?

Last Updated: Mar 12, 2018

I always feel like the Physiodispensers are just micromotors with saline dispensers attached to them. And thus I want to know if I can use a regular surgical micromotor with a 20:1 hand piece and an assistant to irrigate my surgical field to prepare implant osteotomies? Any risks in doing this?

Certainly. Go slowly in dense bone, using an in and out movement, with fresh sharp drills, and have assistant deliver frequent irrigation onto the drill and the the prep site. I’ve done many implants this way for many years with nary a problem.

Good to hear that! But, my concern is the regular micromotors come with torque specs of around 4 Ncm whereas the physio motors give specs of about 50 Ncm. Also I noted that RPM ranges are fairly the same for both! My doubt is whether it'll cut bone?

I have done it in a few cases, but no good control of speed, torque is an issue, can't place the implant with hanpiece (can't have slow speed with hight torque). Dispensing saline is not so easy. So for an easy case it is possible, but on a routine way, not the good way to work. A good unit will last you years (my WH implant unit is 10 years old and close to 900 implants, never fail me, and I have a second just in case (I have everything in back up when I do implant) Get a proper unit you will never look back.

I sure agree with your point doc. But, Implant Insertion can be done with torque wrenches also right? So is it not enough to just prepare the osteotomy and insert the implant with wrenches?

Anon, In my view, wrenches can only get you so far in driving the implant to depth. In many cases, softer bone, immediate placement, less than ideal positioning, a hand piece gives you better control. It will be next to impossible to use a wrench and press laterally to engage the lingual cortical plate for an immediate case. Using a wrench to start the placement would be less stable with more axis of movements compared to stepping on a pedal and placing the implant were it needs to go. These are more nuanced cases of placement which hopefully makes sense. Short story long; get a W/H and don't look back.

I like to place implant in many ways. With the handpiece is a good way in manyntimes, you can control speed and torque. I also use rachet or hand handle. Cutting bone with good spped control to adapt to bone is anither very important thing. In immediat implant you want alow speed, or tapping in very hard bone need very high torque and slow speed. To do bone expansion with Versah drill, etc. A good motor is a great tool. There is even unit on ebay. Or get one with a intro package from implant manufacturer.

I have one unit that I'm watching on ebay! Azdent A-CUBE?? Have you ever heard of it doc?? Any suggestions?

I have only use WH motor.

If you have back up unit then you can take a chance on this type of ebay unit otherwise not worth .These type of unit can fail middle of the surgery causing you lot of grief . I had gone through that once fortunately I had multiple unit so I managed the failure and survived .

I have a WH that I have been using or 7 years with over 2000 implants placed. Never a problem. The WH is the way to go. No need to get all of the bells and whistles just the basic unit. It is the cost of doing business!!!

I would agree with all these comments.I have a W&H unit about 14 years old and almost 6,000 implants placed.I have noted that I have needed to change the handpieces a few times. I also , at times , have used the regular motor as described above if I had a problem with the physiometer , and with care I have not had a problem.

Using physio dispenser with surgical hand piece (speed reduction hand piece ) is the best choice you can control the speed and with same torque you can perform the osteotomy in any type of bone and your surgical kit also should support you with bone tap or thread former.

One of the important points of implant cavity preparation is not to heat the bone while preparation that can be managed by a dispenser by using proper irrigation torque and RPM but using a regular micromotor it is not very easy if you meet a hard bone you will need high torque which is almost impossible by a routine micromotor in that case what you will do is to increas the RPM to over come the resistance of the hard trabecular bone which in turn heats the cavity walls .Before the days of dispensers I used micromotors with irrigation to prepare Lincow blade vents cavities but with a lot of failures so Dear Dr. please do not try this as not to discover America from the start. Good Luck
