Controlled Ridge Splitting (CRS) as an Alternative Technique to Autogenous Block Grafting

Thema

Purpose

Alveolar bone splitting and immediate implant placement have been proposed for patients with severe atrophy of the maxilla in the horizontal dimension. These case reports describe the technique of Controlled Ridge Splitting (CRS) as an alternative to block grafting. Simultaneously, dental implants were placed within the split ridge, surrounded by the particulate mineralized allograft and covered by a absorbable membrane.

Materials and Methods

Twenty cases were completed using the Controlled Ridge Splitting (CRS) technique with simultaneous implants placement. A total of 65 implants were placed in severely atrophied maxilla. Puros mineralized allograft was used to augment the split ridge along with a resorbable collagen membrane (Fig. 4).

Results

Twelve female and eight male patients, at an average age of 68 years with severely atrophied maxillae, were rehabilitated with implants using the CRS technique. A total of 65 tapered implants were placed. The implant diameters ranged between 3.25 and 5 mm with lengths ranging between 10 and 13 mm.  The implants were restored with fixed prostheses and were followed for at least 10 to 24 months. All implants achieved osseointegration and continue to have successful prostheses.

Conclusion

The CRS could be an effective and predictable technique for horizontal ridge augmentation associated with immediate implant placement. This predictable treatment option could be a good alternative to autogenous/allogenic block grafts is severely atrophic maxillae.
