Accuracy of dental implant placement based on surgical temp
Transcript of Accuracy of dental implant placement based on surgical temp
Variation of the dental implant platform position
Variation of dental implant apex positon
Angulation of implant placement
malpositioned dental implant
Accuracy of dental implant placement based on surgical template or free-hand in academic standardized model setting
VRBT shortens the learning curve of restorative procedures and reduces errors to accumulate before they are irreversible
Longer span of edentulous ridge
=> More deviation in premolar area than in the incisor and molar area.
Narrower edentulous ridge and more tilting root
=> More deviation in the anterior area than in the posterior area.

Dental implants placed by
inexperienced surgeons failed twice
as often as those placed by experienced surgeons.

Improve undergraduate dental students’ implant hands-on curriculum, shorten the learning curve of implant placement and reduce mishaps take place while placing implants in real patients.
Different site & other factors?
Hinckfuss et al.,2012.
, surgeon’s experience, and
size of edentulous site
all statistically significantly affect the accuracy of implant placement. An angulation error in the buccal-lingual direction was shown to be less likely to occur in the experienced group.

Surgical template is defined in Glossary of prosthodontic terms as a guide used to assist in proper surgical placement and angulation of dental implants. The usage of surgical template is essential to implant restoration esthetical and functional success.
