Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] This invention relates to a method and apparatus for installing a dental implant in the alveolar or basal bone of a patient. [0002] More particularly, the invention relates to a method and apparatus for a dental implant which reduces the likelihood of the implant becoming infected, which does not require an opening of precise size to be drilled or formed in the alveolar bone to receive the dental implant, which can mount an implant on existing alveolar bone without requiring alteration of the structure of the bone, which prevents the juncture of the dental implant and artificial tooth attached to the implant from being exposed in the event the patient's gums recede, which enables bone mass lost as the patient ages to be replaced, and which enables an implant to be used when drilling an opening in the alveolar bone is precluded due to the existence of a nerve in the bone. [0003] Dental implants are well known in the art. See, for example, U.S. Pat. No. 5,006,070 to Komatsu, U.S. Pat. No. 4,693,686 to Sendax, U.S. Pat. No. 4,812,120 to Flanagan et al., U.S. Pat. No. 4,818,559 to Hama et al., U.S. Pat. No. 4,671,768 to Ton, and U.S. Pat. No. 4,175,565 to Chiarenza et al. Such prior art dental implants and methods for installing the same have disadvantages. [0004] First, the implants normally must be press fit or wedged into an opening formed in the alveolar bone. Force fitting an implant into the alveolar bone is not desirable because it is uncomfortable for the patient, runs the risk of cracking the jaw bone, further damages the bone, and, most importantly, increases the likelihood of infection because dental implants ordinarily are provided with an assortment of ridges, points, or teeth which serve as desirable sites for bacteria, both before and after the implant is inserted in the bone. As a consequence, dental implants typically appear medieval. [0005] Second, force fitting an implant in the alveolar bone requires that the opening formed in the bone have a specific size which roughly conforms to the outer dimensions of the implant so the implant can be force fit into the opening. If a dental surgeon selects a drill of improper size, or waggles the drill while forming the hole in the alveolar bone, the implant may not seat properly in the bone and will work free from the jaw. [0006] Third, the surface area of the portion of the implant imbedded in the jaw is typically reduced because of the common belief that fenestrations of various size must be formed in the implant to permit bone to grow through and anchor the implant. [0007] Fourth, conventional implant procedures often can not be used because the drilling of a opening in the alveolar bone is prohibited by a nerve which passes through the bone. [0008] Fifth, conventional implant procedures also often can not be successfully used when the jaw bone has significantly receded, as can be the case with older patients. [0009] Sixth, conventional implant procedures do not offer a way of replacing alveolar bone which has been lost due to aging or to some other cause resulting in injury to the bone. [0010] Seventh, conventional implant procedures typically do not permit the ready adjustment of the position of the implant after the implant is inserted in the opening formed in the alveolar bone. Correcting the position of an improperly installed implant is often difficult, unless the implant is completely removed from the alveolar bone, which is a time consuming process. [0011] Accordingly, it would be highly desirable to provide an improved dental implant method and apparatus which would not require the force fitting of an implant in the alveolar bone, would not require the formation of a specific size opening in the jaw bone, would provide an implant less likely to loosen after being inserted in the alveolar bone, would permit an implant to be used on alveolar bone housing a nerve, would enable implants to be successfully utilized on alveolar bone which has receded with age, and would permit the position of the implant to be readily adjusted after the implant is inserted in an opening in the alveolar bone. [0012] Therefore, it is a principal object of the invention to provide an improved dental implant method and apparatus. [0013] Another object of the invention is to provide an improved dental implant which can be inserted in an opening in the alveolar bone without requiring that the opening must, within close tolerances, have a specific shape and dimension. [0014] A further object of the invention is to provide an improved dental implant which permits ready adjustment of the position of the implant after the implant is placed in an opening formed in the jawbone. [0015] Still another object of the invention is to provide a dental implant method which permits an implant to be attached to alveolar bone housing a nerve. [0016] Yet a further object of the invention is to provide a dental implant method which allows an implant to be utilized on alveolar bone which has experienced significant loss and recession of its mass. [0017] Another and further object of the instant invention is to provide an improved dental implant which is less likely to loosen after insertion in the alveolar bone. [0018] These and other, further and more specific objects and advantages of the invention will be apparent to those skilled in the art from the following detailed description thereof, taken in conjunction with the drawings, in which: [0019] FIG. 1 is a front view of a dental implant apparatus constructed in accordance with the principles of the invention; [0020] FIG. 2 is a section view of the dental implant apparatus of FIG. 1 illustrating internal construction details thereof; [0021] FIG. 3 is a side view of a portion of the lower jaw bone illustrating the implant of FIG. 1 installed in an opening formed in alveolar bone; [0022] FIG. 4 is a top view of a portion of the jaw bone of FIG. 3 further illustrating the installation of the implant of FIG. 1 therein; [0023] FIG. 5 is a perspective view illustrating a sheet of protective material used to shield hydroxyapatite composition used to pack an implant into an opening in the alveolar bone; [0024] FIG. 6 is a top view of a portion of the lower jaw bone illustrating the insertion of an implant in an opening formed by laterally drilling into the jaw bone; Continue reading about Method and apparatus for installation of dental implant...
