Controlled Ridge Splitting (CRS)

Description:
To demonstrate a new technique of controlled ridge splitting (CRS) in severely atrophied maxillary cases as an alternative to autogenous block graft. Twenty cases were completed using a controlled ridge splitting (CRS) technique with a total of 65 implants were placed in severely atrophied Maxillae and followed after the implants were loaded. Results: The CRS technique was used in very complex cases, where the alternative method will be autogenous block graft. A total of 65 tapered implants were placed. The implants diameter ranged between 3.25-5mm with a length ranged between 10-13mm. The implants were restored and were followed for 1-3 years. All implants achieved osseointegration and continue to have successful prostheses. Conclusion: The CRS is a predictable treatment option and could be a good alternative to autogenous block grafts is severely atrophic maxillae.

Fred; Opacious porcelain was used.

Yes hello I'm not sure if my question was posted so i will ask Dr.Boutros again What type of alloy & porcelain, was used in the recent article Zimmer Eztetic 3.1 to mask out the abutment,I would like to use this technique on similar cases. Thank you, best regards, fred

Beautiful cases. Thanks

Maurice; I try to split the flap when possible but most of the time it ends up a full thickness flap which as you indicated it might compromise blood supply? but we can still can get enough blood supply from the the the flap and bone. The minimum ridge that I was able to split base on a CT is 2.85mm which was shown in one of the cases.

Kevin; You can get the kit from Karl Schumacher here in the US or Zepf in Germany.

Robert, The reason why teeth were extracted was extensive decay and since the patient was involved in a car accident and due to extended hospital stay and due to insurance limitations, the teeth were extracted without any site development. If you like more detailed info about the case I will be more than happy to discuss it.

Indrajeet; Concerning the denture if we are having the patient use the same denture, I would relief any pressure and do a soft reline and if possible I would have the patient hold off on using the denture for at 1-2 weeks. you can get the kit from Karl Schumacher here in the US or Zepf in Germany and the best way is to google the info.

Yosef; You can get the wedges from Karl Schumacher and as far as I know they sell them separate.

Ronnie; Yes I place the allograft between the split ridge and the implants as well followed by the membrane.

Bi-Directional Augmentation of Double-Arched Posterior Maxillary Vertical Defects
Double-arched posterior maxillary defects present a unique challenge requiring special considerations for implant replacement. This deformity is characterized by vertical bone loss from both the sinus aspect as well as the ridge. In this video, Dr. H. Ryan Kazemi demonstrates a bi-directional vertical bone augmentation technique to develop sites that not only support the implants but also improve tissue harmony for enhanced aesthetics, function, and longevity.

Alveolar Ridge Regenerative Strategies: Autogenous Bone vs BMP-2
This clinical based presentation will compare the use of autogenous bone vs BMP-2 for alveolar ridge reconstruction. The science, indications, advantages and disadvantages of each approach will be featured. Single tooth to full arch reconstruction cases will also be shown along with understanding the application of non-resorbable vs resorbable mesh barriers for alveolar ridge reconstruction.

Esthetic Tissue Reconstruction Around Implants - Part 1 of 2 Premium Member Content

Esthetic Tissue Reconstruction Around Implants - Part 1 of 2
Esthetics in implant-supported restorations is an important clinical objective in contemporary dentistry. Understanding the biological behavior of hard and soft tissues following tooth extraction is the first step to anticipate the physiological tissue remodeling and its consequences. Our objective in these 2 sequencial lectures was to provide straightforward decision trees related to several clinical scenarios observed in routine clinical practice. The 3 fundamental pillars for peri-implant excellence are: restorative-driven implant position, hard and soft tissue reconstruction using different biomaterials and grafts, and prosthetic management. Using this philosophical approach seems to provide esthetic and stable results over time irrespective of the initial clinical condition.

Long Term Follow-Up of Dental Implants Placed in Autologous Onlay Bone Graft

Long Term Follow-Up of Dental Implants Placed in Autologous Onlay Bone Graft
The aim of this study was to evaluate the efficacy of autologous intraoral onlay bone grafting (OBG) in correlation with long-term survival rates of dental implants placed in the augmented bone. A retrospective study was conducted on 214 patients who received a total of 633 dental implants placed in 224 autologous intraoral block OBG augmentations, combined with Bio-Oss – mixed with platelet-rich plasma (PRP) and covered by platelet-poor plasma (PPP) – as scaffold, with a follow-up time up to 137 months. We suggest that augmentation of severely atrophied jaw bone through the placement of horizontal and/or vertical intraoral OBGs in combination with Bio-Oss saturated with PRP and covered by PPP should be considered a reliable, safe, and very effective surgical technique for obtaining high bone graft survival rate and high long-term implant survival rate.
