20100075275 | ARRANGEMENT AND DEVICE FOR USING A TEMPLATE TO FORM HOLES FOR IMPLANTS IN BONE, PREFERABLY JAW BONE - An apparatus includes a template which locates hole positions in a jawbone while the template is separated from the jawbone by gum tissue. The template follows a contour of the gum tissue surrounding the jawbone and has guide holes which receive a cutting tool. Anchoring elements attach the template to the jawbone. A system includes means for scanning an implantation site on a patient's jawbone, simulating the implantation site, and determining nerve-rich areas or nerve paths in the jawbone. A holed template is produced which is separated from the jawbone by at least gum tissue of the patient. Attachment hole positions in the jawbone are located so as to avoid nerve paths. A method of forming holes to attach a dental implant to a patient's jaw bone without surgical intervention in gum tissue of the patient to expose the jawbone is disclosed which avoids impingement on a nerve path. | 03-25-2010 |

20130266913 | DENTAL IMPLANT, A DENTAL IMPLANT KIT AND A METHOD OF SECURING A DENTAL BRIDGE TO THE JAW OF A PATIENT - The application relates to an implant for insertion into a structure, a method for connecting a superstructure to the implant, and a kit comprising the implant and a superstructure. The implant comprises a body having an external surface for apposition to bone, an apical end and a coronal end, an insertion interface at the coronal end for engagement with an insertion tool and for inserting the implant in an insertion direction, a connection interface adapted to connect the implant to an connection interface of a superstructure, and a retraction interface for engagement with a retraction member when the superstructure is positioned for connection to the connection interface and being configured for retracting the implant from an applied position in a retraction direction. A gap between the connection interface of the implant and the connection interface of the superstructure may be at least reduced by retracting the implant towards the superstructure. | 10-10-2013 |

20090123887 | DEVICE FOR DETERMINING POSITION - An arrangement for determining position and fixation of an element in a vertical direction and a transverse direction in relation to a part in or on a bone or a model of a bone. A sleeve includes an inner surface. An expansion spacer extends through the sleeve and includes an outer sleeve engaging surface and an inner conical expansion surface. The expansion spacer includes a first flange configured to engage a first end of the sleeve and a second flange configured to engage a second end of the sleeve when the expansion spacer is expanded to vertically fix the expansion spacer with respect to the sleeve. An expansion screw extends through the expansion spacer and includes an outer conical expansion surface configured to cooperate with the inner conical expansion surface on the expansion spacer to radially expand the expansion spacer causing the outer sleeve engaging surface on the expansion spacer to engage the inner surface of the sleeve, thereby determining the position of the sleeve relative to the part and fixing the sleeve causing the expansion spacer to engage the sleeve. Radial expansion of the expansion spacer causes an outer surface of the expansion spacer to be positioned substantially parallel to the inner surface of the sleeve. An assembly template is configured to be arranged on soft tissue overlying the bone and includes a through hole extending therethrough, wherein the sleeve is arranged in the through hole. | 05-14-2009 |
20090239200 | DRILL - A drill is used on a jaw bone with overlying soft tissue and underlying, more solid bone. The drill comprises a first portion which is provided with one or more first cutting edges and with a first width or diameter. Arranged behind the first portion there is a second portion which is provided with one or more second cutting edges and with a second diameter exceeding the first width or diameter. The first portion can cooperate with soft tissues to form an initial hole, and the second portion can cooperate with the soft tissue and the more solid bone in order to enlarge said hole and create a countersunk hole in the more solid bone. The first portion is also depicted to cooperate with the more solid bone, during the second portion's formation of the countersunk hole, in order to provide a guidance hole or marker hole in the bottom of the countersink. | 09-24-2009 |

Modification information which can be introduced into the computer appliance shows a visual dental bridge structure applied on the jaw bone structure with associated teeth and dentine. Orientations for implants are also shown. The computer appliance produces a CAD file which is based on the first information and the modification information. The file is received in a stereolithography machine which issues second information which can be processed in the equipment for production of the physical template which includes through-bores for sleeves which define implant orientation. A working model is produced with the aid of the physical template. The invention also relates to an arrangement of a template produced by stereolithography and by means of information from the computer appliance. | 02-04-2010 |
