A dental splint device for guided robotic surgery, said device comprising: an elongate first splint portion having first and second longitudinal ends (200A, 200B), and a first interface edge extending therebetween; an elongate second splint portion having first and second longitudinal ends (400A, 400B), and a second interface edge extending therebetween, the second splint portion co-extending with the first splint portion with the second interface edge arranged as a complement to the first interface edge; a threaded member engaged between the first and second splint portions (200, 400) and arranged to advance the first and second interface edges (250, 450) toward each other in response to advancement of the threaded member relative to the first and second splint portions (200, 400); a tracking portion engaged with the first splint portion or the second splint portion and extending outwardly therefrom, the tracking portion having a kinematic mount engaged therewith; and an alignment provision (800A, 800B) including a first alignment element (825A, 825B) engaged with the first splint portion and a second alignment element (850A, 850B) engaged with the second splint portion, the first and second alignment elements (825A, 850A, 825B, 850B) being arranged to interact with each other to align the first and second splint portions (200, 400) to provide a substantially consistent gap defined between the first and second interface edges (250, 450), from the respective first ends (200A, 400A) to the respective second ends (200B, 400B) of the first and second splint portions (200, 400), as the first and second splint portions (200, 400) are advanced toward each other by advancement of the threaded member. an elongate first splint portion having first and second longitudinal ends (200A, 200B), and a first interface edge extending therebetween; an elongate second splint portion having first and second longitudinal ends (400A, 400B), and a second interface edge extending therebetween, the second splint portion co-extending with the first splint portion with the second interface edge arranged as a complement to the first interface edge; a threaded member engaged between the first and second splint portions (200, 400) and arranged to advance the first and second interface edges (250, 450) toward each other in response to advancement of the threaded member relative to the first and second splint portions (200, 400); a tracking portion engaged with the first splint portion or the second splint portion and extending outwardly therefrom, the tracking portion having a kinematic mount engaged therewith; and an alignment provision (800A, 800B) including a first alignment element (825A, 825B) engaged with the first splint portion and a second alignment element (850A, 850B) engaged with the second splint portion, the first and second alignment elements (825A, 850A, 825B, 850B) being arranged to interact with each other to align the first and second splint portions (200, 400) to provide a substantially consistent gap defined between the first and second interface edges (250, 450), from the respective first ends (200A, 400A) to the respective second ends (200B, 400B) of the first and second splint portions (200, 400), as the first and second splint portions (200, 400) are advanced toward each other by advancement of the threaded member.
