Effective sterilisation can be the difference between success and failure in implant dentistry.
A Class-B autoclave is the standard of care when it comes to steam sterilisation . This is specially true when sterilising tools and instruments with hollow insides such as handpieces, drills, cannulas etc.
For the last many years my trusted Class B was a unit from Prestige Medical in the UK. In February this year it finally gave in. This, namely the lack of service and spares from foreign manufacturers or their agents has been a constant problem with many imported hi tech equipments. With a complicated , sophisticated expensive and critical device such as a vacuum autoclave it is imperative that service and spares be readily available for many years after the purchase of the autoclave. I was reasonably lucky with my Prestige. Other colleagues have not been so fortunate.
Although many imported brands are available in place of the Prestige we bought the Indian made/assembled Equitron autoclave from Medica Instruments. This is a true Class B autoclave and except for a few initial glitches has performed very well. The service from the CEO Mr.Hemant Shah has been courteous and prompt.
As usual I have NO FINANCIAL INTEREST in this product. Just a product and a company I believe deserves support and encouragement.

Not strictly an implant related post but I just couldn't resist posting. Dr.Sumita Mitra of 3M has played a pivotal role in the development of glass ionomers , specially resin reinforced glass ionomers. Her accomplishments are stupendous and have revolutionised restorative and preventive dentistry. We are all proud of her !

HEINE HRP Binocular Loupes
I would like to add that I have NO financial interest whatsoever in this product!
Dr. Doug Chenin the Director of Clinical Affiars for Anatomage has announced Dynamic CBCT. According to Dr Chenin “Dynamic CBCT features allow you to create dynamic treatment simulations to be used for patient education, increasing case acceptance, and for making the most cutting edge professional presentations or CE material.” Here is an example of a surgery simulation:

These are the images of a simple connective tissue graft I did recently. The advantage I think was that a second surgical site was not needed. The site did not need large volume of tissue. The pictures are self explanatory.

- A twist drill that damaged the nerve while preparing the osteotomy- This is most likely. Although I was as careful as could be (of course!). Hopefully given that all other sensations are normal ,sensation should return sooner or later. Once more the need for careful measurement, preop OPG's and CT Scans and the use of stops. Even better would be the use of a surgical guide with depth control.
- Pressure on the nerve as a result of bleeding ,edema etc in the osteotomy. This too should resolve. Is it worth backing out the implant? Not in the case of a tapered implant such as this. Turning it back even a turn will more often than not result in a loss of stability.
- An accessory canal. Not unknown but the CT Scan of the patient does not seem to show any accessory canals.
- The loss of sensation is easier for the patient to get used to than altered sensation or pain .
