摘要:

A brief history of mechanical tooth concepts is presented with an update and discussion of the three basic categories of designs presently available. The application of mechanical designs to implant dentistry is covered with a discussion of indications, contraindications, and technical requirements for each of the categories.

摘要:

Implant Dentistryand the International Congress of Oral Implantologists have established an annual award in honor of Dr. Ralph V. McKinney, Jr., for the most outstanding manuscript published each year inImplant Dentistry.The $2,500 award, provided by the International Congress of Oral Implantologists, will be presented to the senior author of the selected article at a meeting of the International Congress of Oral Implantologists or one of its component societies. All manuscripts published during a particular year will be eligible for the award.The award-winning article will be selected by a five-member committee chosen by the editor from Editorial Council and Review Board members who do not have manuscripts under consideration for that year. The first award will be presented in 1994 for articles appearing in Volume 2 (1993).Ralph V. McKinney, Jr., DDS, PhD, was Professor and Chairman of the Department of Oral Pathology, School of Dentistry, Medical College of Georgia, and editor of “Endosteal Dental Implants,” published in 1991 by Mosby-Year Book, Inc. Dr. McKinney was active in the founding ofImplant Dentistryand was to be a member of the Editorial Council and one of the oral pathology section editors‘.Dr. McKinney was made an honorary life member of the International Congress of Oral Implantologists in 1991 in recognition of his many years of support and guidance to the organization as well as his many contributions to the advancement of oral implantology.Dr. McKinney died on November 17, 1991.

摘要:

The transmandibular implant system is designed for the reconstruction and rehabilitation of the edentulous mandible utilizing an extraoral approach. Transmandibular implants were placed in 19 patients and mandibular bony changes were followed using standardized panoramic radiography. Eleven sites were identified on each postoper-atiw radiograph and the percentage of radiographic enlargement was calculated for each site. The true bony changes were then computed for both short-term (9.4 months) and long-term (53.4 months) follow-up. Patients with an average mandibular height in the saddle areas of 3.5 to 8.9 mm showed bilateral bony regeneration in the saddle areas and over the most distal cortical screws of the implants. Most of these bony changes were seen in the first year, but continued beyond that time. Patients with residual bone height of 9.0 to 12.9 mm had little bone change, while patients with bone height of 13.0 to 20.5 mm demonstrated slight resorption. Theories for the observed changes are presented. The transmandibular implant is especially indicated for the severely atrophic mandible because its position within the mandible and the rigid box frame design of the implant promote bilateral bone regeneration distal to the framework of the implant.

摘要:

Adjunctive treatment with various chemotherapeutic regimens in implant dentistry are reviewed along with the indications for specific approaches. The use of systemic antibiotics, topical antimicrobials, and various mechanical modalities are discussed in relation to patient maintenance and the repair of ailing implants.

摘要:

Soft tissue complications including gingival hyperplasia, peri-implantitis, inadequate vestibular depth, and insufficient attached tissue may occur adjacent to endosseous implants. In most clinical cases vestibuloplasty and grafting techniques to establish a wider zone of keratinized tissue are not needed. A clinical case is presented involving peri-implant mucosal areas exhibiting persistent inflammation and progressive recession. A free gingival palatal graft was used to correct the soft tissue defects and provide optimal peri-implant health in order to increase the long-term prognosis of the implant reconstruction.

摘要:

The role of a hospital-based implant center with dental and medical specialists working as a team is discussed. Advantages to the team include the availability of sophisticated hospital equipment and facilities. Referring dentists are encouraged to participate in and/or observe treatment performed at the implant center. Four cases treated by an implant team within a hospital environment are presented.

摘要:

A mixture of equal parts of demineralized freeze-dried human cortical bone and nonresorbable porous hydroxyapatite was used in conjunction with expanded polytet-rafluoroethylene membrane to promote deposition of bone in buccal dehiscences around dental implants. Two case studies are presented. (Implant Dent 1993;2:39–41)

摘要:

The restoration of the edentulous mandible opposing all or part of the maxillary natural dentition with implant overdentures is described. There are many situations in which the maxillary teeth opposing an edentulous mandible can and should be retained. Mandibular implant overdentures can be utilized as long as health considerations, morphologic features of the resorbed mandible, and maxillomandibular jaw relationships are satisfactory.

摘要:

Ten N/cm torque has been proposed as the optimum level for the tightening of implant retaining gold screws in order to preload the implant components to limit loosening and fracture. The purpose of this study was to determine the influence of instrumentation and operator experience on the torque generated during manual tightening of slotted gold screws. Sixteen subjects, divided into four groups based on experience, were instructed to tighten five screws into implant analogs with 20-mm and 31-mm slotted screwdrivers. The screws were then removed with a torque gauge. All of the groups of subjects were able to generate significantly greater torque with the 37-mm screwdriver. Dentists with no implant treatment experience generated significantly less torque than the other three groups. Of the 12 dentist subjects, Only 3 generated the optimal amount of torque when using the 20-mm screwdriver. Operators who had little experience dealing with implant prostheses were not able to provide the recommended torque and experienced operators tended to generate more than the recommended amount. None of the subjects were able to generate consistent torque values. (Implant Dent 1993;2:50–52)
