the long-term effectiveness of
dental implant therapy iswell documented
and accepted. The success of dental
implant treatment depends on the correct
3-D position of the implant in the alveolar
ridge, coupled with the correct prosthetic
position of the implant. Traditionally, the
accuracy of the implant position has been
dictated by the skill and experience of the
clinician. Contemporary implant dentistry
aims to eliminate inaccurate placement by
incorporatingadvanceddigitalandimaging
technologies. Guided implant surgery was
developed to increase the predictability
of dental implant treatment outcome by
preoperative planning of the correct pros-
thetic implant position in relation to the
patient’s anatomy, and then accurately
transferring this plan to the surgical field.
Fully edentulous cases with severe
alveolar ridge atrophy, however, pose
significant challenges in this regard. This
is mainly related to the difficulty in accu-
rate positioning and stabilization of the
radiographic and surgical guides, which,
in turn, can lead to the incorporation of
significant errors. Several different tech-
niques, such as bone-supported guides,
soft-tissue-supported guides, soft-tissue-
supported guides with the dual-scan
technique and mini-implant-supported
guides, have been proposed for guided
implant surgery in fully edentulous cases.
In my experience, the most accurate
methods forguided implant surgery infully
edentulous caseswith severe alveolar ridge
atrophyarethebone-supportedguidetech-
nique and the mini-implant-
supported guide technique.
The following cases provide
examples of each technique.
