Outcome Measures

Primary Outcomes (2)

  • patient satisfaction

    Patient satisfaction was evaluated using a questionnaire based on visual analog scale (VAS)

    one year

  • crestal bone loss

    bone loss was measured around the implants in mm

    Two year

Study Arms (2)

• Group 1 (control group)

ACTIVE COMPARATOR

patients who received All on 4 implant-supported fixed restoration. The patients received 2 inclined implants anterior to the mental foramina and 2 vertical implants in the lateral incisor/canine areas.

Device: implant supported fixed full arch prosthesis

• Group 2 (test group);

ACTIVE COMPARATOR

patients who received All on 3 implant-supported fixed restoration. The patients received 2 inclined implants anterior to the mental foramina and 1 vertical implant in the midline of the mandible.

Device: implant supported fixed full arch prosthesis

Interventions

the patients will receive screw-retained cast metal-ceramic fixed prostheses that replace lost gingival tissues with pink porcelain.

• Group 1 (control group)• Group 2 (test group);

Model Details: Patients will be classified into 2 groups according to the implant treatment concept they received: * Group 1 (control group); included 3 patients who received All on 4 implant-supported fixed restoration. The patients received 2 inclined implants anterior to the mental foramina and 2 vertical implants in the lateral incisor/canine areas. * Group 2 (test group); included 3 patients who received All on 3 implant-supported fixed restoration. The patients received 2 inclined implants anterior to the mental foramina and 1 vertical implant in the midline of the mandible.
