Abstract

Objectives: Single-piece Monoblock implants promote the utilization of slightly-aggressive surgical maneuvers to restore
edentulous spans with the least postoperative pain accompanied by a tremendous implant success rate. Moreover, the monoblock
implants could be utilized in cases of several component restorations through Immediately or Progressively- loaded maxillary
and/ or mandibular arches.
Purpose of the study: to compare, clinically and radiographically between free-hand and fully-guided placement of monoblock
implants in total full mouth rehabilitation of edentulous maxillary arches.
Materials & methods: 16 completely edentulous cases were included based on certain inclusion criteria. Conventional
dentures were constructed for all patients followed by, a cone beam radiograph, Patients were randomly divided into 2 groups.
Group (A) is the Free-hand implant placement group and Group (Ba is the ): fully-guided implant placement group. In both
groups, 8 monoblock implants were placed in the central incisor region, canine region, second premolar & first molar region
bilaterally. Clinical assessment included: prosthetic fitness, prosthetic maintenance, and prosthesis comfort while radiographic
assessment included bone density and bone height measurements. Assessments were carried out 3, 6, 9 & 12 months after
implant placement. Patient satisfaction was assisted utilizing a three-point scale patient satisfaction questionnaire.
Results: Regarding Patient satisfaction: a non-significant difference was observed between both groups, on the same line,
Regarding bone healing around implants: a non-significant difference was revealed.
Conclusion: Within the limitation of this study, regarding the relatively small sample size, it could be concluded that the
clinical and radiographic outcomes revealed that, a non-significant difference was observed between both groups, throughout
the whole study period.
