1/71. Use of crestal bone for augmentation of extremely knife-edged alveolar ridges prior to implant placement: report of 3 cases.A technique is presented for interforaminal lateral augmentation of mandibles with adequate bone height, but extremely knife-edged mandibular alveolar ridges (Class IV of Cawood and Howell's classification of residual ridges), in which the crestal portion of the knife-edged ridge is used as grafting material. Following an osteotomy and rotation of the grafts by 180 degrees, the grafts were fixed to the residual ridge below the osteotomy line by means of miniscrews. All grafts showed only mild resorption after a healing period of 3 months, and it was possible to place 4 implants in the now sufficiently wide host region.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/71. Treatment of a patient with severe osteoporosis and chronic polyarthritis with fixed implant-supported prosthesis: a case report.This article reports the treatment and 5-year follow-up of an 80-year-old female with a history of severe osteoporosis and chronic polyarthritis. Treatment included methotrixate disodium and acemetacin. After the last tooth was removed from the mandible, the patient was successfully treated with a fixed mandibular prosthesis supported by 6 implants placed between the mental foramina. The implants have remained osseointegrated, and peri-implant smears have been negative for bacterial colonization. Radiographic follow-up examination has revealed bone loss that is slightly greater than expected. This article focuses on the placement of implants in a patient receiving medication for chronic polyarthritis and osteoporosis.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
3/71. The less than 7-mm edentulous mandible: the implant/overdenture reconstructive option.The edentulous patient with a severely atrophic mandible (less than 7 mm in height) can be successfully restored with two endosseous implants and a clip-bar overdenture, with minimal morbidity. Two of the three cases reported illustrate the long-term potential of this treatment modality.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
4/71. Etiology and management of mandibular fractures associated with endosteal implants in the atrophic mandible.mandibular fractures can occur with the insertion of endosseous implants. Four patients whose mandibles were fractured with the removal or insertion of mandibular endosseous implants are described. Three of the patients required an autogenous bone graft to repair the fracture, and 1 patient was managed with a reconstruction plate. Strategies for prevention and treatment of this uncommon complication are discussed.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
5/71. Immediate loading of titanium hexed screw-type implants in the edentulous patient: case report.Histologic and histomorphometric studies in both animals and humans have shown that more rapid and greater bone-to-implant contact can be achieved with implants that incorporate certain surface characteristics compared with the original machined-surface implants. Such findings are significant because various implant designs may allow the fixtures to sufficiently resist functional loading sooner than originally thought. The case report presented here indicates that immediate loading of hexed titanium screw-type implants in the anterior mandible can lead to successful osseointegration and clinical outcome. The number of implants placed, their distribution, and the type of rigid connection are critical considerations for immediate loading. A bone height that can accommodate dental implants > or = 10 mm long is recommended. Biomechanically, the implants to be immediately loaded must be stable and resistant to macromovement to ensure good osseointegration.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
6/71. Treatment of micrognathia with edentulous maxilla by sagittal split mandibular osteotomy and a subperiosteal implant immobilized with transmaxillary screws.Micrognathia complicated by edentulous maxilla was treated by performing sagittal-split mandibular osteotomy and immobilizing a subperiosteal implant using transmaxillary screws. The patient was a 42-year-old man who had a birdlike facial deformity caused by significant hypoplasia of the mandible. He also demonstrated significant malocclusion attributable to micrognathia and edentulous maxilla caused by resorption of the alveolar bone. These conditions impaired his mastication and articulation, making it impossible for him to eat regular food or carry out normal conversation. A subperiosteal implant was placed on the edentulous maxilla, and was rigidly immobilized to the maxilla using five transmaxillary screws. A prosthesis was then attached to the implant, and by using the implant as the point of reference and the anchor, the mandible was moved forward by sagittal-split mandibular osteotomy. Intermaxillary fixation was subsequently performed. The postoperative course has been favorable, and his facial complexion has improved significantly. One and a half years after his surgery, there has been no sign of complications or malocclusion caused by mandibular retraction. He is now able to eat regular food and speak normally.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
7/71. Using transitional implants during the healing phase of implant reconstruction.The use of dental implants to reconstruct the fully and partially edentulous jaw has been well-documented in the literature. Simplification of the healing phase with transitional implants is becoming a routine step in the management of the integration period for the patient undergoing implant reconstruction. Restoration and maintenance of vertical dimension with transitional implants in conjunction with implant surgical therapy is an effective method to provide the patient with an immediate and comfortable transitional appliance. This approach facilitates the uneventful reconstruction with the definitive prosthesis.- - - - - - - - - - ranking = 0.13618193537348keywords = jaw (Clic here for more details about this article) |
8/71. The milled bar-retained removable bridge implant-supported prosthesis: a treatment alternative for the edentulous maxilla.Restoration of the edentulous jaw with dental implants can be achieved using either an implant-supported prosthesis, such as a fixed bridge, or an implant-retained prosthesis, such as a traditional overdenture. The implant-retained prostheses use edentulous ridges as primary stress-bearing regions, and through stress-breaking mechanisms, the implants are not loaded during function. However, the success rates of maxillary overdentures do not appear to be as good as for mandibular overdentures; this may be attributable to the adverse loading conditions, short implant length, poor quality of bone, number of implants used, flexible bar design, or poor treatment planning. Many articles have also described the numerous problems and multiple visits required in maintaining a traditional bar-retained overdenture restoration, often making it more expensive in the long term than a fixed restoration. The milled bar implant-supported prosthesis offers the benefits of both fixed and removable restorations. Its infrastructure provides the same rigidity as the fixed restoration, owing to the precise fit to the superstructure, which is removable, to promote adequate access for hygiene, yet it still provides lip support and maintains close contact with the soft tissues. These advantages enhance phonetics, esthetics, correct lip support, maintenance, and patient comfort.- - - - - - - - - - ranking = 0.13618193537348keywords = jaw (Clic here for more details about this article) |
9/71. Early intraoral splinting and loading of one-stage dental implants in the edentulous mandible: literature review and case report.Recent studies of immediately loaded screw-retained dentures, bar overdentures, and single-tooth replacements have demonstrated success rates comparable to similar restorations using a two-stage procedure. An international study of immediately loaded bar overdentures on a novel single-stage implant is currently being conducted in the united states and europe. This article presents a case report that illustrates the intraoral construction of an overdenture bar pattern at the time of implant placement, followed by soldering and immediate loading. The elimination of transfer procedures may significantly reduce treatment time and enhance the passive fit of the bar.- - - - - - - - - - ranking = 4keywords = mandible (Clic here for more details about this article) |
10/71. Immediate provisional implants as abutments for an overdenture in the mandibular edentulous jaw: case presentation.Based on the need for provisionalization to provide sufficient phonetics, adaptation, and function following implant therapy, simultaneous placement of immediate provisional implants has evolved to allow abutment positioning following initial surgery. This modality allows the patient to be restored with a stable, functional, and aesthetic restoration during soft tissue healing prior to the removal of the provisional implants. This article presents the clinical protocol for treatment of the edentulous mandible using an immediately provisionalized implant supported overdenture.- - - - - - - - - - ranking = 1.5447277414939keywords = mandible, jaw (Clic here for more details about this article) |
