About this study

Official title: Biting Force and Quality of Life in Porcelain-fused-to Metal Versus Zirconia Implant- Supported in Mandibular Kennedy Class II ( In Vivo Study )

The goal of this randomized clinical trial is to compare biting force and patient satisfaction in three groups. Patients in the control group number one will receive a CoCr removable partial denture, and in the other two groups, implants will be inserted to restore missed posterior teeth (second mandibular premolar and second mandibular molar) in the span area. After three months, implants will be loaded with three units of anatomical PFM-fixed partial dentures in group number two, while in group number three, implants will be loaded with three units of anatomical Zirconia-fixed partial dentures. Biting force will be measured bilaterally at the time of delivery of the removable partial denture and delivery of fixed partial dentures after two, four, and six months. Patient satisfaction will be assessed through a quality-of life questionnaire at the six-months recall appointment

Read the detailed description

Thirty-three partially edentulous patients will be recruited. Patients will be randomly divided into three groups. Patients in the control group number one will receive a CoCr removable partial denture; in the other two groups, implants will be inserted to restore missed posterior teeth (second mandibular premolar and second mandibular molar) in the span area using a two-stage surgical technique with the help of a radiographic and surgical stent. Pre-surgical and post-surgical prescription of antibiotics, anti-inflammatory drugs, analgesic drugs, and mouthwash for one week, then a follow-up will be done at the suture removal appointment. After a three-month osseointegration period, implants will be loaded with three units of anatomical PFM-fixed partial dentures in group number two, while in group number three, implants will be loaded with three units of anatomical Zirconia-fixed partial dentures. Recall appointments will be scheduled for the patients two, four, and six months after loading for the collection of the data. Biting force will be measured using a biting force sensor for both the intact and restored sides at the time of delivery of the removable partial denture and at the loading of implants after two, four, and six months. Patient satisfaction will be assessed through a quality-of-life questionnaire at the six-months recall appointment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of biting force

    improvement of Biting force in two different implants supported partial dentures.

    Measured: Biting force will be measured by newtons unit per minute using a biting force sensor for both the intact and restored sides at the time of delivery of the removable partial denture ( baseline ) and at loading of implants, after 2, 4, and 6 months.

Secondary outcomes (1)
  1. Oral health-related quality of life ( OHRQoL ) Measurement

    OHRQoL was measured by using the original version of the Oral Health Impact Profile OHIP-14, which has been shown to be valid and reliable. The questionnaire included sevendomains-functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap-with two questions each.

    For each item responses were never, hardly ever, occasionally, fairly often and very often.

    Items were scored on a 5-point scale ranging from 0 (never), to 1 (hardly ever), 2 (occasionally), 3 (fairly often) and 4 (very often)

    Measured: At the time of delivery of the removable partial denture ( baseline ) and at loading of implants, after 2, 4, and 6 months. Patient satisfaction will be assessed through a quality-of-life questionnaire at the recall appointments.

Model description
Control group (1) will receive a CoCr removable partial denture; in the other two groups (2) and (3), implants will be inserted to restore missed posterior teeth (second mandibular premolar and second mandibular molar) in the span area using a two-stage surgical technique with the help of a radiographic and surgical stent. After a three-month osseointegration period, implants will be loaded with three units of anatomical PFM fixed partial dentures in group (2), while in group (3), implants will be loaded with three units of anatomical Zirconia fixed partial dentures.
