| Abstract | ||||
| Single-piece implants promote the use of minimally invasive techniques in restoring edentulous spans with a superb implant survival rate. Also, a one-piece implant can be utilized with Immediate or Progressive loading protocols. Aim of the study: This study was to compare the accuracy of the traditional impression technique versus the scanning impression used in full-maxillary rehabilitation with Monoblock implants. Materials & methods: 12 completely edentulous patients from the prosthodontic department-Cairo university were selected, following specific inclusion criteria. For group(I) patients, a CBCT was taken, and 8 Monoblock implants were planned to be placed in specific positions bilaterally. Then, a direct impression was taken after implant insertion. For group (II) patients, the same was done as in Group (I). Then, intra-oral scanning was made instead of the traditional technique. Patients received final acrylic full arch restoration within 5-7 days only 7 it was in occlusion in centric only & free in any eccentric movements. Where Patients strictly asked for soft dieting for 4 months. Patients were recalled periodically at 3, 6 & 9 months respectively. Meanwhile, patients' satisfaction and radiographic measurements were measured Results: Repeated measures ANOVA test was used to investigate the changes by time inside each group besides, to compare the two groups. Bonferroni's post-hoc test was encountered when the ANOVA test is significant. A student's t-test was performed to compare satisfaction outcomes. Conclusion: Intra-oral scanning is an easy, feasible, and time-saving technique for full mouth rehabilitation in terms of prosthesis accuracy regarding radiographic outcomes & patients' satisfaction. | ||||
