摘要:

The insertion of dental implants is multifaceted. Adequate containment of the implant body requires not only a measurable volume of bone but also an acceptable density of this osseous foundation. Through interactive computerized axial tomography (CAT), not only are such measurements conveyed to the clinician, but vital structures that should be avoided or at least accounted for are portrayed in a three-dimensional manner. Predictability is enhanced, and the implants can be directed for prosthetic use in conjunction with surgical guides (templates). (Implant Dent 1998;7:19–25)

摘要:

Once the decision has been made to construct a maxillary implant-supported overdenture prosthesis, implant location and number are important determining factors for palatal design. Eight clinical scenarios are described.Four cases require full palatal coverage, and four cases permit modified palatal coverage. Only two, with an increased number of implants and more posterior locations, permit a completely open palatal design similar to fixed prostheses. (Implant Dent 1998;7:29–33)

摘要:

A system is introduced in which dental implants are specifically designed for containment within four different categories of bone densities. The sizes and the textured surfaces that accompany the gradations of lengths and diameters are standardized for each bone type. A modified thread design focuses on compression of bone rather than on shear, and the geometry of the entire implant body reflects features that are concurrent with a “platform effect.” Having been tested by means of finite element analysis and initial animal studies, the results are provided herein for the placement of 364 consecutive implants in five clinical centers on human patients, with surgical survival results of 98.9 percent overall. The initial clinical report of these implants indicates that all bone densities may have similar initial survival rates. (Implant Dent 1998; 7:35–42)

摘要:

A stable occlusal plane is achieved with the combination of two maxillary, implant-supported milled bars securing an overdenture and bilateral, mandibular-fixed partial dentures. Overdenture retention is enhanced with attachments. Guide planes assure proper alignment of the overdenture for easy patient insertion and improved prosthesis stability. A reliable technique for verifying the accuracy of the master cast is also presented. (Implant Dent 1998;7:45–49)

摘要:

Implant dentistry is no longer a new field, but there is still plenty of room for it to grow. Over the years, implant dentistry has grown steadily but. not as quickly as it could. Because of the high degree of complexity and high costs associated with practicing implant dentistry, the growth of composite bonding, for example, quickly surpassed that of implants. Although each is an answer to a desperate dental service need, composite bonding provided the only answer, whereas implants have much less costly and less complex alternatives, i.e., dentures. However, with the emergence of high technology in dentistry and young dentists who are motivated to use high technology and practice higher revenue-oriented dentistry, the author believes that implant dentistry will soon begin to grow much more quickly than it has over the last 10 years. As technology continually facilitates and improves the results of implant dentistry, patients will begin to realize the limitation of dentures and will become more comfortable with finding a permanent, more attractive, and more valuable alternative.
