Questions & Comments
Muray Arlin - (11/4/2013 3:24 PM)

My long-term data that I follow on my “Triton DIMS” system does not document the suspected reasons for failures so I can only give my clinical impressions. Once an implant is integrated I rarely see a late loss of osseointegration that I think is due to mechanical overload. However there are 2 clinical situations where this may happen or appear to happen. One is that sometimes we see progressive late angular bone loss that some feel may be due to biomechanical overload where in fact I suspect that the implant was never fully osseointegrarted in the first place i.e. perhaps there was a very thin fibrous seam that passed the osseointegration assessment but once under load the fibrous seam “opened up”. The one area where I do feel I sometimes see a late loss of oseointegration due to biomechanical overload is with very short (e.g. 6mm length) implants, especially unsplinted implants with fixed restorations in the posterior area. I have followed many 6mm Straumann implants in my practice with up to almost 20 years of follow-up and while the early survival rates are good (e.g. 94% as published in my JOMI article of 2006) my longer-term follow up has found that my survival rates have dropped to the mid 85% range due to several “late failures” and I have not seen this pattern with implants of 8mm or longer

Edward, I believe that your colleague is correct to the extent that the operative word is "physiologic" forces. If indeed an implant is well integrated, "physiologic" forces should not cause a LATE implant failure. Hypothetically, however, often its difficult to determine if... a well integrated short implant with a large crown to root ratio and having significant horizontal forces placed on it... if the forces on such an implant are indeed "physiologic"? We do know that "pathologic" forces will create crestal, peri-implant, stress patterns and bone loss around the implant and that may contribute to late failure. We also certainly know that pathologic forces will contribute to mechanical type failures.

Edward Gelfand - (10/29/2013 9:25 AM)

An oral surgeon colleague, has recently stated, that he does not believe that mechanical loading is a cause of LATE implant failure......in other words, once the implant is well integrated, physiologic forces are not capable of causing loss of integration..... What is your opinion on this statement, in relating to your extensive data bank? Thanks, Alec Lupovici

Larry;
Try contacting Dr. Murray Arlin by going to his Xpert page here on XP and ask about the software he used in his office.
I'm sure he will respond as do most of our Xperts. Good luck.
Maurice

would like to know if I could get similar software progam to do database on my implants

thanks

Alternative & New Tendencies for Alveolar Reconstruction in Modern Implant Dentistry
Knowledge of bone biology and physiology are crucial for successful dento-alveolar reconstruction. The presentation will review the natural healing process of the bone and the sequence of events needed for proper regeneration. This process will then be discussed and compare with the present materials and technologies available in the market including alloplastics and allogenic materials. The role of the Stem Cells and rh-BMP2 will be exposed as part of these new trends in alveolar reconstruction for modern implant dentistry. Multiple cases will be presented demonstrating the versatility and outcomes in different clinical situations based on biological, bio-mechanics, and implant aesthetic needs.

Prosthetic Soft Tissue Development From Single to Full Arch Reconstruction Premium Member Content

Prosthetic Soft Tissue Development From Single to Full Arch Reconstruction
In addition to surgical intervention is the creation of the specific emergence profile that is essential in the aesthetic zone. The emergence profile composed of 2 parts, the abutment and the subgingival part of the crown. The shape of abutment can be individually shaped so that it gives natural appearance and varies individually (depending on the depth, angulation and diameter of the implant). Sometimes it even dictates the implant position. From a surgical perspective, soft tissue height, position and thickness need to be diagnosed and corrected when needed. From the prosthetic point of view, the emergence profile has to be created to mimic the natural appearance and maintained over time in respect to the biological changes. The course teaches step by step how to be successful with implant prosthetics from single tooth, partially edentulous to full arch reconstruction.

Does residual cement around implant-supported restorations cause peri-implant disease? A retrospective case analysis
The purpose of this study was to determine the relationship between patients with a history of periodontitis and development of cement-related peri-implant disease. Seventy-seven patients with 129 implants for this retrospective analysis were selected from completed implant cases that were scheduled for regular maintenance or had experienced mechanical or biological complications between years 2006 and 2011 in private practice. Implants with extracoronal residual cement and implants without cement remnants were analyzed.

Techniques for the Use of CT Imaging for the Fabrication of Surgical Guides
Implant dentistry has evolved into one of the most predictable treatment alternatives for partially and completely edentulous patients. The initial excitement about successful osseointegration has allowed clinicians to offer an extended set of treatment alternatives that include single tooth replacement to full mouth reconstruction. Pioneering protocols of the early 1980s relied on a two-stage surgical approach that allowed for the biological aspects of osseointegration to be achieved at the cellular level, insuring long-term success. These procedures often required extended periods of time to complete. Through strategic marketing and word of mouth, demand for implant-related treatment continues to grow and has compelled clinicians to search for new and improved methods to deliver such care within a shorter time period without sacrificing accuracy. As treatment protocols have progressed...
