One 60 years-old patient was scheduled for left posterior maxillary ridge augmentation due to failure of standard implants, followed by successful maxillary dental implants. We used an unproved technique consisting in a mixture of 50% allogenic and 50% xenogenic bone supported by reabsorbable membrane. No complications were found at the different stages of the treatment, and at the ending the patient showed a good level of satisfactory outcomes. Radiological evaluation demonstrated ridge augmentation able to support implant, and within the graft islands of connective and bone-like tissue was found. Within these tissues osteoclasts and osteoblast putative cells were found. Results demonstrate that the used method in addition to support implants has osteogenic and bone remodeling activity.

The aim of this study was to analyze the success rate of dental implants and the graft shrinkage rate after vertical ridge augmentation and simultaneous implantation with an allograft bonering. Fifty-one patients (81 augmentations and simultaneous implantations) were included. The bonering technique followed a standardized protocol. The alveolar ridge was prepared using a congruent trephine, and depending on the defect size, an allograft bonering with an outer diameter of 6–7 mm was placed. The height of the bonering was trimmed with a diamond disc to the required length. The average height of vertical augmentation was 5.5 mm. Implants were inserted through the bonering into the native bone of alveolar ridge. After 6 months, dental implants were exposed, and dental prosthetics were placed. Of 81 implants placed with the bonering technique, two failed during a 12-month follow-up, corresponding to a success rate of 97.5%. One year after surgery, the allograft bonering exhibited an average vertical graft shrinkage rate of 8.6%. In conclusion, the allograft bonering technique was associated with a favorable outcome, and in cases with large vertical defects, both treatment time and donor site morbidity could be reduced.

The aim of the present study was to report the clinical case of a patient with a vertical defect of the alveolar ridge, which prevented the installation of dental implants without first treating the defect in question. A 32-year old female patient with a height defect of approximately 6 mm in the region of the missing absent teeth (13 and 14). The patient was treated using the sandwich osteotomy technique, with the interposition of a block bone graft of bovine origin. No complications were reported in the post- operative period. After seven months, two dental implants were installed in the relevant region. The bovine bone graft was incorporated into the relevant area. The bovine bone block graft used in this clinical case was shown to be a viable option for interposition between bone segments that have been osteotomized via sandwich osteotomy.

Adequate Quantity

The anatomic limitations of the residual alveolar bone may cause problems for the insertion of dental implants because implant placement requires an adequate quantity and quality of bone. Ridge augmentation has been performed to reconstruct alveolar ridges as support for the placement of dental implants with a high success rate. However, a staged approach requires multiple surgeries and more treatment time. In this report, the patients were treated with dental implantation with simultaneous ridge augmentation in both submerged and nonsubmerged cases. The prostheses were well in function without any probing depth or gingival inflammation up to final evaluation. It may be suggested that dental implantation with simultaneous bone grafting may be an option when the graft material can be well stabilized around the implants. Further evaluations over long periods of time are needed to monitor the clinical results.

Introduction. The role of the total lower denture is not only to replace the missing teeth but also to provide the substitute for a range of supporting tissues which have diminished due to the process of resorption, to re-establish the original relations in the region of jaw complex, to support the surrounding soft tissues which have lost their natural support, and, moreover, to be unobtrusive and discrete substitution of lost functions. Application of Mini-dental Implants. If anatomical conditions are unfavorable, there is a wide range of oral-surgical pre-prosthetic procedures which can be performed on both soft tissues and bone structures (vestibuloplasty, alveolar ridge augmentation...) in order to enable proper fabrication of the total lower denture to some extent. Having in mind the old age of the patients, the majority of who suffer from chronic diseases such as diabetes mellitus, cardiovascular problems, systemic diseases etc., these procedures should be avoided because of the extent of the procedure, possible systemic complications and prolonged therapy period. Conclusion. Most recently, the application of titanium endosteal mini implants have proved to be one of good solutions in overcoming unfavorable anatomical conditions resulting in stability and retention of total lower dentures.

Edentulous Jaws

Abstract Atrophic edentulous jaws can pose a significant challenge to successful oral rehabilitation with endosseous dental implants. Although ridge augmentation can help to restore ridge volume, grafting procedures can significantly increase patient morbidity, costs, and treatment time, depending on the case, before dental implants can be placed. This article reports on an alternative technique used in 3 patients to expand ridge volume and place dental implants in a single procedure. A partial-thickness flap was elevated to expose the alveolar crest, and conventional implant osteotomies were partially prepared. Along the crest of the ridge, a furrow with terminal vertical releases 1 to 3 mm deep were created, and a bone chisel was used to deepen the furrow. Osteotomes were used to complete preparation of the implant receptor sites, and the implants were placed. Bony plates were stabilized through the use of resorbable sutures. Furrows more than 2 mm deep between the plates were augmented with a xenograft. Collegen membranes were placed over the sites, and soft tissue was sutured. Healing was unremarkable, and all implants were successfully restored. For these patients, the ridge expansion technique resulted in substantial bone reconstruction with little or no grafting. Long-term, prospective studies on this procedure are required before definitive conclusions can be drawn.
