Immediate Loading Of Dental Implants In Mandible Full-Arch: A Pilot Clinical Study On Patients Satisfaction, Quality Of Life And Implant Success

Objective: To provide 2-year clinical- and patient-oriented data with regard to mandibular overdenture assisted by 2 immediately loaded unsplinted implants.

Detailed Description

In this pre-post design, Phase-I clinical trial, 18 edentate individuals received a new set of complete denture. Then, following standard procedures, 3 threaded implants (OsseoSpeed TXTM, Dentsply Implants, Mölndal, Sweden) were placed in the mandible in each patient, and locator abutments (Zest Anchors LLC, Escondido, U.S.A.) were inserted on the right and left side implants. The midline implant served as a control for within-patient comparison. The immediate loading was conducted within 24 h of surgery. Data were collected at baseline (T0), 12 (T1) and 24 (T2) months after immediate loading. The clinical outcomes included implant survival rate, crestal bone level changes and implant stability. These criteria were assessed through clinical and radiographic examinations as well as resonance frequency analysis. Patient-centered outcomes included patient satisfaction and oral health-related quality of life measured using validated questionnaires. Brunner-Langer approach was used for statistical analysis.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient Satisfaction With the Immediate Loading Protocol
Time Frame: 4 months
Visual Analogue Scale (VAS) to assess patients' satisfaction, with a score of 100 being extremely satisfied (minimum and maximum scores: 1-100 respectively).
4 months
Oral-health-related Quality of Life With the Immediate Loading Protocol
Time Frame: 4 months
Oral Health Impact Profile (OHIP-20) to assess oral-health-related quality of life: score ranges between 20 and 120 points, with a lower score indicating a better oral-health-related quality of life.
4 months
