摘要:

&NA;There has been an increase in the use of the resorbable membranes that do not require a second stage surgery for removal in guided bone regeneration. The purpose of this review is to discuss the immune response of the host to the collagen, the use of resorbable membranes derived from Type I collagen of bovine Achilles tendon around dental implants, and its potential significance in the future of dental implantology.

摘要:

&NA;The posterior edentulous mandible presents unique challenges for implant reconstruction because of deficiencies in bone quality and quantity. Autogenous mandibular block grafts can be used in a predictable manner to enhance bone volume and density, allowing for placement of maximum diameter implants to facilitate stress distri bution for long‐term implant survival. This article will feature the importance of staging and recipient site preparation using mandibular block autografts for posterior mandibular edentulous reconstruction. (Implant Dent 2000;9:67‐75)

摘要:

&NA;Press‐fit implants can be used to meet the prosthetic needs of patients who require immediate loading of their implants. This procedure may be necessary because of a patient's unwillingness and/or inability to tolerate a removable prosthesis. The implants reported in this study had a similar success rate to those immediately loaded screw‐type implants previously reported by others. The lack of large numbers of long‐term immediately loaded implants dictates the need for detailed informed consent when using immediately loaded cylinder implants for dental reconstruction.

摘要:

&NA;To help reconstruct the osseous support for a missing interdental papilla between two adjacent dental implant, an inter‐implant papillary template®has been conceived and fabricated. This titanium housing or stent carries the bone grafting mixture to protect the process of osteogenesis during the healing period. It eliminates the need for harvesting bone from another area in the oral cavity. Because the placement of this titanium component is bone at the first stage of surgery (that is, at the implant placement stage), there is no need for another surgical invasive procedure. This article describes the shape, manipulation, and the handling of the inter‐implant papillary template®. (Implant Dent 2000;9:85‐89)

摘要:

&NA;The mandibular deformation as a result of jaw movement from rest position has been studied and documented by other authors. Here, we report that there is a possible correlation between this phenomenon and the discomfort experienced by a patient rehabilitated with implant‐supported restoration for the mandibular arch during function. The recovery from pain and symptoms was achieved only after splitting the prosthesis into three sections. This case report serves to remind clinicians of the importance of following biological concepts as the key to a successful result. (Implant Dent 2000;9:90‐95)

摘要:

&NA;Passive‐fitting mesostructures and superstructures are required to be superimposed on osseointegrated endosseous implants. The tightening of an inaccurate framework to the abutments will transmit stresses to the bone‐implant interface. Precision, until now, has been inconsistent and unpredictable with conventional methods of casting, soldering, and welding techniques. By machining the framework with the Spark Erosion method using electrodischarge machining, a substantial improvement in the passive seat of the prosthetic elements is achieved. Chemical reactions caused by galvanic corrosion are also important factors in the precise approach to the treatment planning of implant‐supported prostheses. The application of a pure 11.8% grade 1 titanium casting system allows the restorative team to fabricate porcelain‐fused‐to‐metal crowns and bridges, conventional fixedremovable restorations and implant prostheses in pure titanium within completely biocompatible parameters that are absolutely mercury free. This article explains why the spark erosion machining and the unique titanium casting system have a significant impact on today's implant dentistry. (Implant Dent 2000;9:96‐101)

摘要:

&NA;Fixed prosthetic implant reconstruction of the edentulous maxilla demands skill and state‐of‐the‐art techniques of both the surgeon and the restorative dentist. As discussed in Part I (Implant Dent.1999;8:186‐193), accurate diagnosis and treatment planning are essential to successful, predictable clinical results. How and where implants are placed have a lasting impact on the quality and prognosis of the final restoration. A series of clinical guidelines and considerations is reviewed with illustrative clinical treatment protocols of edentulous maxillae of unfavorable anatomy including attendant prosthetic difficulties. This article addresses the fixed implant rehabilitation of edentulous maxillas with inadequate posterior bone and favorable arch position, inadequate posterior bone and unfavorable arch position, and inadequate anterior and posterior bone and unfavorable arch position.
