Design and biomechanical evaluation of a cementable endosteal blade implant.

A cementable endosteal blade implant has been developed and evaluated. Inherent in the design are the following factors: minimization of stress concentrators, ease of implantation, and high resistance to loosening. Other potential advantages of this design as compared with conventional endosteal blade implants include reduced hazards of postoperative infection and reduced likelihood of metallic corrosion. Six conventional endosteal implants and six cementable implants were installed in steer mandibles using standard dental surgical techniques and Simplex-brand methyl methacrylate bone cement. They were loaded in uniaxial compresstion at a loading rate of 0.0122 in./min. the stiffness (S), deformation at 900-lb load (D900), proportional limil (PL), and load at 0.04 in. deformation (L0.04) were calculated for each test. The cementable design showed a twofold increase in stiffness, only 17% of the deformation at 900lb, more than twice the proportional limit, and at least twice the load at 0.04 in. deformation when compared with similar values for the conventional endosteal implants. This study reveals that, in addition to being unstable in bone, conventional endosteal implants are also unstable when used with acrylic bone cement. The new design should eliminate most of the problems associated with endosteal blade implantation.

The use of blade implants in a selected population of partially edentulous adults. A five-year report.

Based on the findings observed after the insertion of 33 blade implants in 23 patients, ages 31 to 74, for periods up to 60 months, the following conclusions can be made: (1) The blade implant is a technically feasible procedure which can be maintained in the mouth for period up to 5 years, although some degree of bony breakdown will be seen in a majority of the patients at this time; (2) The degree of breakdown around blade implants is almost exclusively located to the locus of the neck of the implant and is most likely due to the lack of attachment at the epithelial-implant interface.

Retrieval analyses of a blade implant after 231 months of clinical function.

A blade implant that was retrieved in 1990 after 231 months of clinical function (since 1971) was analyzed with respect to clinical, histological, and biomechanical characteristics. The implant clinical records demonstrated no abnormalities or pathological lesions over the tenure of treatment. The bone to implant interface showed a mixture of interfacial tissue components and conditions with adequate direct bone contact (46.4 to 82.3 percent) for classification as osseointegrated. The abutment fracture leading to removal was characterized as a cyclic fatigue mechanism and the distribution of tissue components along the interface could not be correlated with specific biomechanical loading directions. This report considers the clinical and biomechanical records as they relate to the detailed histological investigation.

Quantitation of retention of endosseous dental blade implants in dogs.

This research was initiated in order to study the extraction forces associated with solid, single-vented and multi-vented blade dental implants placed in mandibles of dog for 2 months. An extraction device was used to measure the extraction forces on five of the implants and a histological study was carried out around the sixth multi-vented implant. The main finding was that the extraction forces for the multi-vented blade implants were 6 to 12 times those of the single-vented and solid blades. Other findings in this study were: none of the implants exhibited mobility; sulci ranged from 2 to 3 mm at the implant neck; bone covered the implant shoulder. There was gross and histologic evidence of bone growth in the vents of the multi-vented blade; close adaptation of the bone, connective tissue capsule and implant; and no gross, histologic, clinical or radiographic evidence of bone pathology.

Correlative transmission electron microscopic and scanning electron microscopic observations of the tissues supporting endosteal blade implants.

Correlated scanning electron microscopic (SEM), routine transmission electron microscopic (TEM), and high-voltage transmission electron microscopic (HVEM) observations demonstrated that one-stage and two-stage endosteal blade-type implants were well-supported by mandibular tissues after five months of unloaded healing in dogs. Areas of the implants were apposed directly by mineralized tissues without any apparent interposed unmineralized connective tissue. Other areas of the implants were apposed by narrow areas of unmineralized tissue, often containing osteoblasts. These unmineralized areas were interposed between the implant and a supporting mineralized matrix. A healthy mix of tissues, which represented a dynamic osseous complex, supported these serviceable blade-type dental implants. This study, for the first time in the dental implant literature, utilizes HVEM stereology for evaluation of the bone-implant interface.

[Endosseous blade implantations in the edentulous patient and the prosthetic superstructure].

Our suprastructures for blade vent implants are purely tissue-borne constructions. The retainers fixed to the denture base (Dolder jacket or Gilmore rider) are attached to the implant bar to guide the movement of the saddles. In addition, this is to counteract lifting to the dental replacement by the tongue or the muscles of the floor of the mouth. Cases in which this therapeutic method was applied are presented.
