## Abstract

A method for preparing a surgical guide for positioning of a dental implementation. The method includes positioning a positioning device relative to a model jawbone, translating the positioning device in a BL direction, adjusting a BL angle of the positioning device about a BL pivot axis corresponding to a desired position of a top of the dental implementation, and fixing the BL position, BL angle, and z-height of the positioning device. A mounting assembly mounts to the positioning device and includes a removable rotation block with a guide hole. The mounting assembly is movable in the MD direction while the BL position is fixed. A template fixes the mounting assembly for transferring the positioning information to a patient's mouth. Various aspects of the design process can be performed on a computer. The guide and a method of using the guide to perform an implant procedure are also disclosed.

## Claims

### Claim 1

A method of preparing a surgical guide for buccal-lingual (BL) and mesial-distal (MD) positioning of a dental implementation, the method comprising:
preparing a Computer-Aided-Design (CAD) model of a patient's dental arch using a computer system, the CAD model of the patient's dental arch including at least a portion of a jawbone adjacent an edentulous area;
virtually positioning a positioning device relative to the jawbone adjacent the edentulous area, using the computer system, such that the positioning device is aligned along a BL position axis extending through the jawbone within the edentulous area;
mapping a virtual template on the CAD model of the patient's dental arch, using the computer system to establish model data;
manufacturing a physical template and a physical guide insert based on the model data, wherein the physical template removably receives and registers the position of the physical guide insert with respect to the patient's dental arch, and wherein the physical guide insert includes a guide hole extending along the BL position axis.

### Claim 2 (depends on 1)

The method of claim 1, wherein the physical guide insert is configured to be positioned above the edentulous area of the patient's dental arch.

### Claim 3 (depends on 1)

The method of claim 1, wherein the physical guide insert is configured to be adjustable in a MD direction with respect to the physical template.

### Claim 4 (depends on 1)

The method of claim 1, wherein the virtually positioning the positioning device includes translating the positioning device in a BL direction to a desired BL position axis that is in-line with the jawbone region, adjusting a BL angle of the positioning device about a BL pivot axis corresponding to a desired position of a top of the dental implementation to be positioned, the BL pivot axis being located on the BL position axis, and fixing the BL position and the BL angle of the positioning device relative to the model.

### Claim 5 (depends on 1)

The method of claim 1, wherein the virtually positioning the positioning device includes setting a z-height of the positioning device.

### Claim 6 (depends on 1)

The method of claim 1, further comprising mounting the physical guide insert on the physical template, wherein the mounting includes:
translating the guide insert in a MD direction to a desired MD position relative to the jawbone region;
adjusting a preliminary MD angle of the guide insert about an MD pivot axis, the MD pivot axis being coextensive with the BL position axis, and
affixing the guide insert to the physical template corresponding to the model.

### Claim 7 (depends on 1)

The method of claim 1, further comprising mounting the physical guide insert on the physical template, wherein the mounting includes:
translating the guide insert in a MD direction to a desired MD position relative to the jawbone region.

### Claim 8 (depends on 1)

The method of claim 1, further comprising mounting the physical guide insert on the physical template, wherein the mounting includes:
adjusting a preliminary MD angle of the guide insert about an MD pivot axis, the MD pivot axis being coextensive with the BL position axis.

### Claim 9

A system for preparing a surgical guide for buccal-lingual (BL) and mesial-distal (MD) positioning of a dental implementation, the system comprising:
a computer system configured to prepare a Computer-Aided-Design (CAD) model of a patient's dental arch, the CAD model of the patient's dental arch including at least a portion of a jawbone adjacent an edentulous area;
the computer system being configured to virtually position a positioning device relative to the jawbone adjacent the edentulous area, such that the positioning device is aligned along a BL position axis extending through the jawbone within the edentulous area;
the computer system being configured to map a virtual template on the CAD model of the patient's dental arch, using the computer system to establish model data;
one or more manufacturing devices configured to manufacture a physical template and a physical guide insert based on the model data, wherein the physical template removably receives and registers the position of the physical guide insert with respect to the patient's dental arch, and wherein the physical guide assembly includes a guide hole extending along the BL position axis.

### Claim 10 (depends on 9)

The system of claim 9, wherein the physical guide insert is configured to be positioned above the edentulous area of the patient's dental arch.

### Claim 11 (depends on 9)

The system of claim 9, wherein the physical guide insert is configured to be adjustable in a MD direction with respect to the physical template.

### Claim 12 (depends on 9)

The system of claim 9, wherein computer system is configured to virtually position the positioning device by translating the positioning device in a BL direction to a desired BL position axis that is in-line with the jawbone region, adjusting a BL angle of the positioning device about a BL pivot axis corresponding to a desired position of a top of the dental implementation to be positioned, the BL pivot axis being located on the BL position axis, and fixing the BL position and the BL angle of the positioning device relative to the model.

### Claim 13 (depends on 9)

The system of claim 9, wherein the computer system is configured to virtually position the positioning device at a z-height of the positioning device.
