NCT06150768

Brief 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

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (1)

  • Oral health-related quality of life ( OHRQoL ) Measurement

    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.

Study Arms (3)

Control group Cobalt Chromium Removable Partial Denture

ACTIVE COMPARATOR

The patient will receive a Cobalt Chromium Removable Partial Denture to restore missing posterior teeth in Kennedy Class II cases. The denture will be fabricated by conventional lost-wax and processing techniques.

Device: Cobalt Chromium Removable Partial Denture

Implant-Supported Porcelain-Fused-to-Metal-Fixed Partial Denture

EXPERIMENTAL

Two dental implants will be placed to restore missed posterior teeth (second mandibular premolar and second mandibular molar) in Kennedy Class II cases by 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 Implant-Supported Porcelain-Fused-to-Metal-Fixed Partial Denture

Device: Implant-Supported Porcelain-Fused-to-Metal-Fixed Partial Denture

Implant-Supported Zirconia fixed partial denture

EXPERIMENTAL

Two dental implants will be placed to restore missed posterior teeth (second mandibular premolar and second mandibular molar) in Kennedy Class II cases by 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 implant-supported Zirconia fixed partial dentures

Device: Implant-Supported Zirconia Fixed Partial Denture.

Interventions

The patient will receive Removable Partial Denture to restore missing teeth in Kennedy Class II cases.

Also known as: Combined Removable Partial denture.
Control group Cobalt Chromium Removable Partial Denture

The patient will receive Implant-Supported Porcelain-Fused-to-Metal-Fixed Partial Denture to restore missing teeth in Kennedy Class II cases.

Eligibility Criteria

Age40 Years - 55 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Kennedy Class II mandibular arch where the last standing abutment is the first premolar, opposed by a fully dentate maxilla (either natural dentition or fixed prostheses).
  • A minimum of 12 millimeters of bone height above the inferior alveolar canal diagnosed from the pre-operative cone beam CT.
  • Sufficient inter-arch space to accommodate the implant supported fixed partial denture.

You may not qualify if:

  • Patients with bone or mucosal diseases.
  • Heavy smokers.
  • Patients with uncontrolled metabolic disorders such as diabetes mellitus.
  • Patients with parafunctional habits.
  • Patients with conditions that might complicate the treatment, such as: severe gag reflex, limited mouth opening.
