All-On Four-流行か現象か

Description:
The All-on-Four protocol uses fewer implants, generally four or five, that are placed at mechanical inclinations to maximize support in the fabrication of fixed implant supported prosthetics in fully edentulous patients. The use of angled implant placement allows the clinician to avoid encroachment of anatomic structures such as the sinus, nasal floor or mandibular canal that may make vertical placement difficult or impossible without significant grafting of deficient sites. This webinar with Dr. George Duello and Dr. Maurice Salma will discuss the various treatment options available today for this patient segment and emphasize when and where the All-On-Four protocol can be successfully utilized to eliminate the need for costly augmentation procedures and months of healing time.

Dr. Pate, The malleable guide is available through Nobel Biocare. Dr. Duello

Dr. Murphy, Both arches were included but the majority of the implants were not tilted. Dr. Duello

Great Video course. When Dr. Branmark placed all on four 10mm implants in his patients did that include the upper arch or just the lower arch. smiledds@aol.com Dr. Murphy

Dr Duello,

What ce do you recommend to learn more about this specific protocol. Also, where can I purchase the pilot hole malleable implant guide you featured on this video.

Thanks

Dr Pate

To Webinar Attendees, Someone asked what to you do if you have an implant failure under an All-on-Four. Remove the prosthesis, remove the implant, graft-delayed implant placement, and keep the prosthesis on the remaining three implants until the new implant has healed. Then you have two choices--remake the entire prosthesis or section the prosthesis where the previous implant has failed and now healed, section the bar and prosthesis, argon laser weld a new section to fit the new implant and replace the fixed All-on-Four prosthesis on the implants. If any one has any other thoughts I would be glad to review them. Dr. Duello

Dear Dr. Smith, I agree with your clinical observations. This is why good diagnosis, adequate alveoloplasty, and excellent laboratory support is necessary to attempt to achieve a prosthesis the has convex or flat anatomy on the intaglio surface so that oral hygiene is possible. However, I also find that overdenture prosthesis can be problematic with gingival hyperplasia under bars that many times leads to psuedo pocketing around abutments/implants. Occasionally I have had patient who can't seat their overdenture due to tissue impingments. I think all prosthesis require constant observation/monitoring with appropriate intervention when tissue problems arise. Thank you for your comments. Dr. Duello

Dear Dr. Kozy, I don't have any cases over 6 years old that meet the definition of "All-On-Four" that was discussed in the webinar on DentalXP as I started using the Malo technique in 2005. However, I have numerous other cases using four implants in the maxilla and mandible. Most of these cases on overdentures with bar and various attachments. As I stated in the webinar, I have modified my philosophy and now use All-on-Four to provide patients with a fixed prosthetic treatment. I hope this answers your question.

The beauty in implant dentistry is that every case is an individual challenge. An ideal implant treatment uses procedures , techniques, materials and technologies that leads fast and on the shortest way to a maximally aesthetic result. This is our goal, in every clinical case, from single tooth replacement to full arch reconstructions.

The Socket Shield Technique - Have the Rules of the Game Changed in Aesthetic Zone Implant Therapy?
Implant therapy is in the age of being increasingly aesthetically driven, not merely restorative. With the increasing popularity of immediate implants, particularly with anterior tooth extraction, the relevance of socket changes following extraction has come to the fore. Contrary to what was originally believed, the installation of an immediate implant does not arrest bone loss, and immediate implants in the aesthetic zone are prone to recession of bone and soft tissue as a result of bundle bone resorption which is obligatory with tooth extraction.

Immediate Implants: Partial / Full Arch Rehabilitation & GBR - Part 2
By scientific studies produced in recent years has been confirmed, in selected cases, the validity of the post-extraction implants. The use of this method implies a lower emotional impact, a single surgery and a healing often better for the patient. We will be discussed traumatic extraction methods, perfect insertion of the implants with or without bone regeneration with bone substitutes and membranes and the opportunity to combine an advanced method as immediate implant with the execution of an immediate loading to restore aesthetics in more complex cases.

Complex Case Rehabilitation in Light of New Technologies
This case report describes a step-by-step full arch restoration (upper and lower), rehabilitated utilizing new technologies in dentistry. CAD/CAM technology has changed not only the technician's working process, but also the clinician's, offering new benefits to clinical workflow.For example the possibility of using zirconia and its characteristics as a restorative material. The clinician's and technician's professional backgrounds and relationships are critical to achieving optimal aesthetic and functional results; while prosthetic success depends upon an in-depth knowledge of the materials and their properties and on carefully performed clinical procedures, which are still of utmost importance to obtain satisfactory results.

Prosthodontics, Periodontics & Orthodontics: A Multidisciplinary Approach to Implant Dentistry
Many aspects of various dental disciplines must be integrated to constitute a sound total approach to implant dentistry. Aside from the surgical elements - encompassing implant placement, position, angulation, and length - the creation of appropriate spaces to accommodate the three-dimensional final prostheses may require use of orthodontic techniques as well. And establishing and maintaining a sound periodontal environment is essential to implant integrity, from the outset of placement to finalization of the prosthetic suprastructure.
