インプラントにおける抜歯窩マイクロギャップと治療のオプション

Description:
In this second of an ongoing informative and clinically relevant series, Dr. Dennis Tarnow, Professor & Chairman, Dept. of Implant Dentistry New York University College of Dentistry, discusses extraction site management with special emphasis on the biology and clinical treatment options of the micro-gap that occurs after immediate implant placement into an extraction site. Specifically, Dr. Tarnow tries to answer such questions as what is the critical jumping distance, should we graft the micro-gap, and how should we manage the soft tissue flap in immediate extraction and implant placement.

Gabe, the literature tells us that there may be bone and osseointegration on the labial of the implant even without grafting the GAP, however, the buccal plate will remodel and we do see a general loss of bucco-lingual dimension after this modeling takes place especially when no bone grafting is done in the extraction gap. What does that mean to us in the anterior region? Well, we will have bone on the labial of the implant, but we may have a concavity in the soft tissue contour and/or, color/optic deficiencies of the soft tissue. Along with bone grafting the extraction site, a connective tissue graft is often utilized in esthetically demanding areas with thin biotypes to compensate for this possibility. Having said that, If all you're looking for is osseointegration then grafting the gap may not be absolutely necessary as long as you can protect the fibrin clot.

Wow...Does this mean no more grafting implant microgap so long as I have a buccal bone?

Robert ,its the clot that will stabilize the particulated graft materials inside the Gap.

Robert Carimi - (7/16/2016 7:23 PM)

What keeps the bone particulate from washing out around the implant if no membrane or primary closure is achieved? Dr. Tarnow showed a case where he filled in the buccal gap with particulate, placed a healing abutment and pt left with only a flipper. Thank You!

Nice proof of your hypothesis! (11/2009) What about today? (Oct-Nov 2015) Buccal socket defect >2mm+ Do you and Dr Chu treat all (most) of your non-graft (clot only) implant cases this way? What about a grafted implant case? Place a membrane for security or rely on what you've shown here? Looking forward to your response.

Nice to hear from you again .

Mohannad Al Juhaini - (9/1/2013 6:01 AM)

Thank you for a nice presentation. what would be the oral hygiene instruction in such case ? what about if by mistake a food particle got dislodged in between the implant and the bone ? what if the blood clot didn't form ? Thank you in advance

peer-emil charles-harris - (8/29/2013 4:44 AM)

Thank you Henry, I shall continue to bone graft and connective tissue graft my anterior esthetic cases.

henry salama - (8/27/2013 8:22 AM)

peer-emil, there is nothing in the literature that supports the story-line of the resorption of the buccal plate in 4 years. Having said that, the literature tells us that the buccal plate will remodel and we do see a general loss of bucco-lingual dimension after this modeling takes place especially when no bone grafting is done in the extraction gap. What does that mean to us in the anterior region? Well, we will have bone on the labial of the implant, but we may have a concavity in the soft tissue contour. Along with bone grafting the extraction site, a connective tissue graft is often utilized in esthetically demanding areas to compensate for this possibility.

Restoration of Optimal Esthetics in Complex Clinical Situations Premium Member Content

Restoration of Optimal Esthetics in Complex Clinical Situations
Patients often neglect or delay dental care for an extended time because of their negative experiences with and fear of dental treatments. This neglect may result in the advance of periodontitis with severe bone loss, a substantial number of missing teeth, and problems with the remaining teeth. Preexisting malocclusion can aggravate this condition. This case report demonstrates an interdisciplinary strategic approach, in combination with the use of biologically grounded, clinically proven, and viable techniques and technologies to restore optimal esthetics and function in such complex cases. The authors emphasize the importance of carefully planning the timing and sequence of performing periodontal, orthodontic, and implant therapies. The advanced techniques and technologies successfully implemented in this case report include the growth factor and titanium mesh (Ti mesh)-assisted bone augmentation; ovate pontic-mediated, noninvasive soft tissue contouring; and photofunctionalization

OCCLUSION: Can We Possibly Simplify It? Part 3
Over the past 20 years, many of us have been confused, frustrated, unsure and crazy about ... “How do I get my occlusion philosophy on the right path?” At NYU FMR we have developed tried and true techniques that are guaranteed to make you understand occlusion, contact points and mandibular movement that makes sense, is easy to diagnose and systematically treat with success. In addition being comfortable Restoring OVD, understanding TMJ joint position and treating the worn dentition. Using our SOT methods and Level 1-10 Occlusion Classification we can show you how to become successful in the “Occlusion” of your patients.

A Novel Surgical-Prosthetic Approach to Optimize Peri-Implant Tissue Esthetics Premium Member Content

A Novel Surgical-Prosthetic Approach to Optimize Peri-Implant Tissue Esthetics
The achievement of an aesthetic implant-supported restoration is a constant challenge to the restorative dentist. Due to the circular shape of the implant and its smaller diameter, when compared to the root of a natural tooth, a dilemma inevitably occurs of how to construct an artificial crown that will imitate the natural tooth crown form. The appearance of the surrounding soft tissue is of major importance, and various techniques have been developed to guide its topography. The Marginal Migration Concept is a technique that helps the clinician in order to achieve a long-term predictable outcome in the Aesthetic zone by enhancing the surrounding tissues. The lecture will show step-by-step clinical procedures from diagnostic models through surgery with immediate provisional restoration therapy to the definitive restorations.

Advanced Immediate Implant Placement Strategies Including the Socket Shield (SS) Technique and its Complications
Immediate implant placement in the aesthetic zone has become a controversial topic with regards to the long term aesthetic demands that both the profession and our patients have placed on this treatment modality. Since the controversy broke a few years ago there have been a number of outstanding developments that have revolutionized the way we do immediate implant placement. Soft tissue augmentations using the tunnel technique as well as the socket whiled technique are 2 of these techniques which form the baseline of treatment in our clinic. This lecture will go through all the updated protocols of immediate implant placement supported by the literature as well as deal specifically with the finer details of the socket whiled technique including step by step photos and video of the technique. More importantly it will cover numerous complications that we have had to deal with over the last few years that we have been doing this technique.

Diagnosis, Planning, & Treatment of Altered Passive Eruption; From a Periodontists Perspective
This presentation will teach how to diagnose cases of altered passive eruption based on the radiographic evaluation (with peri-apical rx and CBCT) and how to plan and document a surgical procedure aimed to ‘uncover’ the beautiful and natural hidden enamel. In a world where esthetics is becoming more and more a concern a simple periodontal plastic surgical procedure can re-establish esthetic and balance to the patients affected by this condition.
