Creative Ridge Expansion Solutions Utilizing Ultrasonic Technologies
Description:
Management of the narrow ridge is a common challenge in modern prosthetically-driven implant dentistry. Treatment using a simple and highly predictable procedure for alveolar ridge expansion can be employed using new techniques and technologies which will be introduced on this presentation.

Very well done presentation. So many pearls on the technique. Thank you so much.

Good points of comparison between GBR and ridge split . Great presentation . Thank you

Thank you Dr Moghaddaa. In those cases of 4mm and less - If the position of the crest is in a favorable prosthetic position then I prefer to split. If the bone is more ligualized than I elect to augment. Using proper cuts with piezo along with bone expanders we can prevent labial fractures. Often just a horizontal cut can be enough. Omitting inferior cuts as well. Secondly we must use a narrower implant as to not over expand the plates. Therefore platform switch implant that can handle molar forces is pre requisite.
Thank for your question. Hope to see you in NY for symposium.

Isaac , congrats, very well documented .
my question: in cases with ridge width less than 4mm, by considering the possible risks like fracture of the buccal plate,do you prefer to go for ridge splitting or you prefer to do the GBR ?
all the bests

Dr Salama - my humble thanks for your comments and questions. They are some of the more common and important questions regarding this technique.
Minimum crestal ridge thickness would be 3mm. 1 mm cancellous 1 mm cortical on each side.
There can be incredible regenerative potential when splitting and grafting as long as we don't pack our graft too tightly between the 2 cortical segments. I've found that the access to the medullary blood supply is even greater than when we decorticate during ridge augmentation procedures.
Keeping the periosteum intact works wonderfully as long as we have enough bone remaining on both sides of our implants. If there is 6mm of crestal bone we can simply split without a full thickness flap as you mentioned quite predictably. With less thickness often cortical vertical releases are necessary and reinforcing those cuts with mineralized grafting material enhances our alveolar outcome.
We've seen many cases with bone loss when too much stress on the crestal ridge is employed. Using a narrow implant design is paramount to avoid stress so a platform switching implant is important to provide an appropriate occlusal restorative table for our molars. In addition the increasing development of piezo devices has reduced necrosis in these cases.
Regards

There are so many different versions of ridge splitting/expansion. I like your technique and excellent documentation. A few questions for you; 1. What is your "minimum" ridge thickness that you would consider splitting the ridge? 2. Many maintain the periosteum on the buccal segment, do you feel it is important? 3. Many have reported some crestal bone loss with this approach after healing and loading? Have you seen a similar result? thanks Dr. Salama

Ronni - zirconia abutments must have ti base as well. Full zirconia abutments are subject to fracture. The key is that the ti base must be tall enough. Often labs will shorten them thus loosing surface area for zirconia to bond with. Ti base should be treated with monobond or z-prime and a good cement like multi link hybrid should be employed. Of course this is all done at the lab level. There is nothing wrong with screw retained emax either although zirconia does handle stronger compressive forces. I've had only 2 come off on several hundred implants over the last 4 years and a simple recementation was done in office. Happy implanting.

I have been using zirconia abutments for a little while and in the posterior I recently had two implant crowns become loose and the problem was the Zirconia internal hex broke away from the abutment so in the posterior crowns I went back to screw retained emax with titanium base.

Subperiosteal Implants - The New Approach for the Extreme Atrophic Jaws
Subperiosteal implants started in the 40’s but were discontinued due to the poor success rates in the long term.
Today, 80 years later, a completely different technology has emerged, bringing Subperiosteal implants to the next level.

Preservation of the Bundle Bone: Reality or Myth
The loss of teeth will lead to resorption of the buccal plate with its resultant need for extensive augmentative procedures (both bone and soft tissue) as well as the risk of poor long term aesthetic stability. Partial Extraction Therapies (PET) are techniques that allow us to maintain the buccal bone plate and hence prevent the collapse of the alveolar bone creating a platform for ideal soft tissue and bone which is stable in the long term. This is a greater problem in the aesthetic areas. This lecture will take you through the different options with regards to immediate implant placement as well as the most cutting edge PET in a step by step fashion.

Atrophic Posterior Maxillan and Mandible: Alveolar Ridge Reconstruction with Mandibular Block Autografts
Autogenous bone grafts have been used for many years for alveolar ridge augmentation and are still considered to be the gold standard for jaw reconstruction. The use of these grafts with osseointegrated implants was originally discussed by Brånemark et al., who used the iliac crest as the donor site. For repair of most localized alveolar defects, however, bone grafts from the mandible offer advantages over iliac crest grafts. These include the proximity of donor and recipient sites, convenient surgical access, decreased donor site morbidity and decreased cost. This article focuses on posterior maxillary and mandibular osseous augmentation in a staged approach for implant placement. Both horizontal and vertical deficiencies are addressed with the use of symphysis and ramus buccal shelf donor block bone via case presentations.
