a dental instrument covered partially by the housing;

a plate extending from the connecting portion of the housing; and

an overlay device comprising:

(i) a tooth contacting surface; and

(ii) a cutting guide having a first slot defined by a first wall, a second slot located between the first wall and a second wall of the cutting guide, and an end wall extending between the first wall and the second wall, wherein the second slot extends through the end wall and is configured to receive the plate, wherein the connecting portion of the housing is configured to slide within the first slot of the cutting guide while the main body is located outside the cutting guide and as the plate slidably moves within the second slot of the cutting guide, wherein a width of the plate in a first plane is greater than a width of the first slot in a second plane parallel to the first plane;

a width of the main body of the housing in a third plane parallel to the second plane is greater than the width of the first slot in the second plane; and the connecting portion has a length substantially equal to a thickness of the first slot; and

wherein the dental instrument is movable within the housing, such that movement of the housing and movement of the dental instrument within the overlay device is limited with respect to the tooth contacting surface.

2 . The system of claim 1 , wherein the tooth contacting surface includes one or more sides for contacting portions of one or more teeth in a mouth of a patient to secure the overlay device with respect to a tooth.

6 . The system of claim 1 , wherein the first slot is configured to limit a lateral movement of the connecting portion.

7 . The system of claim 1 , wherein the first slot is adjacent to the second slot.

8 . The system of claim 1 , wherein the second slot is defined by one or more parallel surfaces of the first wall and the second wall of the cutting guide.

9 . The system of claim 1 , wherein the first and second walls of the cutting guide are parallel to each other.
