1/15. 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 = 1keywords = jaw (Clic here for more details about this article) |
2/15. 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 = 1keywords = jaw (Clic here for more details about this article) |
3/15. 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 = 4keywords = jaw (Clic here for more details about this article) |
4/15. Treatment of advanced periodontal destruction with immediately loaded implants and simultaneous bone augmentation: a case report.BACKGROUND: Advanced periodontal destruction is often associated with extraction of the teeth. Oral rehabilitation in these cases may include the traditional prosthetic restoration or an implant-supported reconstruction. Immediately loaded implants present an alternative treatment modality using a bar in the anterior mandible, along with the placement of higher numbers of implants, which are connected with a fixed prosthetic reconstruction. methods: This clinical case report presents the surgical and prosthetic rehabilitation in a patient who had lost all teeth due to advanced periodontal bone destruction. Six implants were placed in the upper and lower jaw each. Some implants required guided bone regeneration in conjunction with autologous bone grafting. All of the implants were connected with their abutments, and a temporary fixed restoration was placed immediately after surgery. The final metalloceramic-fixed reconstruction was cemented after 6 weeks of loading. RESULTS: All of the implants were osseointegrated and showed no clinical signs of mobility or infection. Mobility values were evaluated during healing and were found to be reduced. Radiological findings showed a stable peri-implant bone level during the total 18-month loading observation period. CONCLUSIONS: This case report presents an alternative treatment concept for the oral rehabilitation in a patient with advanced periodontal destruction. The concept of immediate loading of implants might provide a better opportunity to meet patient needs than more traditional treatment modalities.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
5/15. orthognathic surgery and implants.The resorptive pattern of the maxilla and mandible after the dentition has been lost often leads to a discrepancy between the jaws such that a significant Class III malocclusion occurs. This discrepancy between the jaws leads to problems with both fixed and removable prosthetic reconstruction of the jaws with teeth. The jaws are often resorbed to the point where the muscle attachments become dislodging forces for conventional dentures and also to the point where adequate implants cannot be placed. Various procedures have been developed to augment the alveolar ridges to allow for adequate reconstruction of the dentition. orthognathic surgical procedures have been developed to reposition the jaws and have been traditionally used in the dentate patient to correct a skeletal malocclusion. These procedures are usually carried out with orthodontic control of the dentition to produce the best results. These same procedures can be used on the edentulous patient to correct the discrepancies between the jaws in order to reconstruct the dentition with implants. Bone grafting procedures are often required for these procedures so that the alveolus can be augmented at the same time and allow for dental implants to be placed at a later date.- - - - - - - - - - ranking = 6keywords = jaw (Clic here for more details about this article) |
6/15. Case report: restoration of edentulous mandible with 4 BOI implants in an immediate load procedure.dental implants for insertion from the lateral aspects of the jaw bone have been described repeatedly, since 1972. Long term results have been reported. Due to their design, BOI-Implants (basal osseointegration) can be installed even in those cases, where the vertical bone supply is reduced. This applies to the distal areas of the maxilla and the mandible. Furthermore, BOI-implants allow immediate loading as long as a balanced masticatory function can be achieved and maintained. This paper reports on the steps taken to install a full lower bridge in 4 BOI-implants and restoration in a patient with a circular bridge. The bridge was made from CoCr-Alloy and covered with acrylic resin. This treatment technique reduces costs and treatment time by about 50% compared to conventional techniques.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
7/15. Implant-supported bar-latch overdenture for the severely atrophied, edentulous jaw: a case report.The removable implant-supported prosthesis is the treatment of choice in some clinical situations. Despite its technically demanding fabrication and the resultant high cost, the bar-latch overdenture provides stability and is easy for patients to manage. A case report illustrating the surgical and prosthetic procedures of this treatment option, including laboratory fabrication, is presented.- - - - - - - - - - ranking = 4keywords = jaw (Clic here for more details about this article) |
8/15. Dentofacial rehabilitation by osteodistraction, augmentation and implantation despite osteogenesis imperfecta.osteogenesis imperfecta-- a heritable systemic disorder characterized by enhanced bone fragility-- is frequently associated with a Class III malocclusion and distinct dental disorders. This patient, suffering from a late form of osteogenesis imperfecta, displayed early loss of teeth and severe maxillary hypoplasia. Bone grafting of the alveolar ridge was assumed not to guarantee a neutral basal relation before dental implantation. Due to the risk of atypical fractures conventional orthognathic surgery was excluded in the atrophic maxilla. In contrast to a conventional Le Fort I osteotomy, osteodistraction of the maxilla can be performed omitting the precarious down-fracture procedure. Despite a lack of reports on this technique in patients with osteogenesis imperfecta, dysgnathia was corrected by osteodistraction of the upper jaw. The loss of teeth was treated by augmentation of the alveolar crest using autogenous bone from the iliac crest followed by placement of dental implants. Stable normocclusion of the implant-supported overdentures was achieved without any detectable relapse over 4 years. For the first time it has been demonstrated that advanced surgical techniques like osteodistraction, alveolar crest augmentation and dental implantation can successfully be combined for dentofacial rehabilitation even in patients suffering from osteogenesis imperfecta.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
9/15. Treatment planning of the edentulous maxilla.The predictability of successful osseointegrated implant rehabilitation of the edentulous jaw as described by Branemark et al., introduced a new era of management for the edentulous predicament. Implant rehabilitation of the edentulous maxilla remains one of the most complex restorative challenges because of the number of variables that affect both the aesthetic and functional aspect of the prosthesis. Among the prosthesis designs used to treat the edentulous maxilla are fixed or removable implant-supported restorations. Since the aesthetic requirements and preoperative situation of each patient varies, considerable time must be spent on accurate diagnosis to ensure patient desires are satisfied and predictable outcomes are achieved. The purpose of this article is to compare the treatment options and prosthesis designs for the edentulous maxilla. Emphasis will be placed on diagnosis and treatment planning. Criteria will be given to guide the practitioner in deciding whether a fixed or removable restoration should be placed. This objective will be accomplished through the review of cases with regard to varying design considerations and factors that influence the decision-making process.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
10/15. Gigantiform cementoma showing apparent activity on a bone scan.A bone scan in a Negroid female suspected of myeloma showed no uptake other than in the jaws. A panoramic radiograph revealed multiple mixed-density lesions, in particular in the mandible, suggestive of gigantiform cementoma. The significance of this association is discussed.- - - - - - - - - - ranking = 1keywords = jaw (Clic here for more details about this article) |
