A Cavitron Is Not a Microscope: Why Precision Matters in Implant Rescue Cases
Cavitron is not a substitute for a microscope in implant rescue. Learn why precision and magnification matter most.

Implant Mechanical Rescue (IMR) is simply the process of recovering or rescuing a case which has suffered a mechanical failure in the supporting implant hardware. Failure can occur for various reasons but if it does, it can involve retrieving fractured screws or abutments, or other components. Additionally, if possible, the central question of ‘why did it fail’, needs to be forensically determined so future repeat failure can be avoided.
Our main goals are:
(A) to help patients who are in need of qualified care for implant mechanical failure; and (B) to help dentists successfully diagnose the problem and treat the situation, or refer to a qualified dentist. (Dentists may experience difficulty with implant mechanical failure in their own cases or in new cases presented upon referral.)

Our main goals are (A) to help dentists who have experienced difficulty with implant mechanical failure, either in their own cases or presented upon referral, to successfully diagnose the problem and treat the situation to the level expertise or refer to a qualified dentist and (B) patients who are in need of qualified care.
Component system failure can potentially be caused by one or more scenarios including contact between teeth (occlusal design), patient based failure, a random event, implant manufacture defects, or accuracy in design of the case. Our team is trained to assist you in gathering information up front in order to help determine if the implant, screw or abutment is broken and what attempts were already made to resolve the problem. Dr. Mastrovich has experience with over 1500 cases that support his efforts to decrease failure and increase success.
With over 1500 cases successfully performed since 2009, on over 38 implant systems, Dr. Mastrovich is sought after for guest lectures and training. He has lectured to dental study clubs, as well as the larger groups of several hundred dentists to more than a thousand each of the times he has spoken at the Academy of OsseoIntegration. For both dental professionals and patients, Dr. Mastrovich has the ability to present his cutting-edge findings, algorithms and techniques in an accessible and understandable format with relatable examples and case studies.

Our goal is to establish a network of dental practices that have committed the effort to position themselves so they can be a “center of referral” for these cases and be highly predictable in the outcomes by utilizing appropriate tooling, microscope visualization, and access to certain precision tooling when needed. Additionally, only the practices involved will be reporting their cases to a common database for statistical analysis of what field, venues, and recovery system used. If many practices are reporting, the database could be large enough to have statistically meaningful data.

Implant Mechanical Rescue (IMR) retrieves broken implant screws and abutment fragments. Learn what IMR is—and what it isn’t.
What every patient should know about what steps to take when their dental implant screw or abutment breaks.

They start by making sure you understand what to expect during your visit. Then during your visit, Dr M describes what he sees and helps you understand options using language you can understand.
Should you have any issues with your implants that your dentist cannot resolve, Dr Mastrovich is your first call. I cannot recommend him and his staff highly enough!!
Great service saved two implants no dentist could save. Priceless.
Excellent Specialist
I had a broken abutment screw inside my dental implant, and I was very fortunate to have Dr. Mastrovich handle the situation. He was able to carefully and successfully remove the broken part of the screw from the implant, avoiding damage to the implant itself.
Dr. Mastrovich was extremely knowledgeable, professional, and meticulous throughout the procedure. He explained the situation clearly and gave me confidence that I was in good hands.
I’m very grateful for his expertise and the excellent work he did. I highly recommend Dr. Mastrovich to anyone who needs help with a complicated mechanical implant problem.
Dr. Mastrovich and his office staff were amazing! They walked me through every aspect of this process and demonstrated a real desire to understand what went wrong with my implant so it doesn’t happen again. His experience was very evident and he was super accurate with his work, leaving me with no pain, even after the numbing wore off. I really appreciated his staff, Valerie was very communicative leading up to the appointment and made me feel comfortable. Lori was so good with making sure I was comfortable even though I was a little nervous during the procedure. Overall, fantastic office and I would highly recommend them to anyone needing specialty work like this!
Dr. Mastrovich and his team were recommended to me after a titanium screw broke off partway into an implant. They successfully removed the end of the screw and inspected the inside of the implant with a microscope to make sure there were no defects in the thread. They were very helpful and clear with e-mail communications between myself and several other doctors leading up to the appointment.
