Eligibility
Age
18 Years to 100 Years
Inclusion criteria
Inclusion criteria: Sufficient bone structure for conventional length implants insertion, verified by CBCT; suitable mouth opening for surgical and tomographic guides, as well drill guides and drills for GVS technique; presence of both teeth adjacent to the dental element that was rehabilitated, for stabilization of the guides.
Exclusion criteria
Exclusion criteria: Anatomical limitation for dental implants placement or the need of bone grafting prior to implantation; patients with inflammatory alterations at the surgical site; limited prosthetic space that can preclude the restauration; pregnant or lactating women; presence of metabolic, hemorrhagic and relevant systemic disorders that could alter the tissues reparation.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the angular deviation between the planned and executed position of dental implants in two different techniques: guided virtual surgery, using a stereolithographic surgical guide, and conventional surgery, with the aid of a surgical guide made by hand.;The results of the present study reject the null hypothesis. It was possible to observe that angular deviations of the implants installed by GVS (test group) were 2.2±1.1 degrees while those installed by CS (control group) had a mean of 3.5 ± 1.6 degrees. | — |
Secondary
| Measure | Time frame |
|---|---|
| To compare the linear deviation between planned and performed implants, in cervical, central and apical positions.;For the variables coronal, central and apical distances (deviations), however, the null hypothesis was accepted, that is, the means between the groups of GVS and CS were the same, statistically.;To assess the trans and post operative results of both techniques by means of a questionnaire answered by the patients.;Only nine patients who completed the survey accepted to fill the postoperative questionnaire or did it correctly. Due to the small sample size of this analysis (n=18), Fisher's exact test showed no statistical difference for any of the questions. | — |
