Clinical Trial Summary

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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Evaluation of biting force	improvement of Biting force in two different implants supported partial dentures.	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	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)	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.
