About this study

Official title: COMPARISON OF PATIENT SATISFACTION AND DIMENSIONAL ACCURACY OF INJECTION MOLDED PEEK AND BRE-FLEX MATERIALS FOR BOUNDED REMOVABLE PARTIAL DENTURES (Randomized Clinical Trial)

Evaluation the patient satisfaction and dimensional stability of upper removable partial denture constructed from two different flexible thermoplastic materials.(BRE-FLEX and PEEK).

Read the detailed description

The assessor is responsible for all clinical procedure that will be conducted in this study during all the visits:

Panoramic radiograph and periapical radiographs will be made on the prospected abutment teeth to evaluate the crown-root ratio, the apical condition of the abutment and their alveolar bone support.

The preliminary impression will be performed with irreversible hydro-colloid impression material (alginate), The impressions will be poured with type IV dental stone to obtain diagnostic casts. Maxillary Face-bow will be recorded. The diagnostic casts will be mounted on semi adjustable articulator in centric occluding relation to evaluate the interarch distance and occlusal plane.

Special trays will be constructed and Mouth preparation will be performed by preparing guiding planes and rests seats will be prepared opposing to the edentulous area. Final impression will be taken by elastomeric impression material. The impression will be poured into type IV dental stone in order to obtain master cast. The master cast will be surveyed. The proposed design will be as follows: metal framework base saddle for edentulous areas on both sides connected with palatal strap. Aker's clasp on all abutments with buccal retention. The denture base will be tried in with acrylic teeth in patient's mouth. After that, the denture base of the partial denture will be processed incorporation with the metal framework into the two different materials to be evaluated. The first group will receive the partial denture in which the metal framework incorporated with the denture base fabricated from PEEK material. The second group will receive the partial denture in which the metal framework incorporated with the denture base material fabricated from BRE-FLEX.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PEEKOther

    Polyetheretherketone (PEEK) is a synthetic, tooth colored polymeric material that has been used as a biomaterial in orthopedics for many years but recently used as removable prosthetic material. Advantages of this polymer material are elimination of allergic reactions, high polishing qualities, low plaque affinity, and good wear resistance.

    It has been proven that it shows high mechanical and biological properties. Studies evaluating the properties of this material are limited and need more clinical tests.

  • Bre.flexOther

    Bre.flex is a nylon-based thermoplastic material, composed of nylon PA 12 (polyamide).Nylon exhibits high physical strength, heat resistance and chemical resistance. It can be easily modified to increase stiffness and wear resistance. Nylon resin can be semi-translucent and provides excellent esthetics but it is a little more difficult to adjust and polish.

What is being measured

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

  1. patient satisfaction

    The first week at the time of insertion measuring patient satisfaction immediately after partial denture insertion, The third week measuring patient satisfaction of the partial denture, The fourth week measuring patient satisfaction of the partial denture.

    the patient satisfaction is measured by questionnaire.

    Measured: 1 month

Secondary outcomes (1)
  1. dimensional stability

    The first week at the time of insertion measuring the dimensional stability immediately after partial denture insertion.

    The third week measuring the dimensional stability of the partial denture,The fourth week measuring the dimensional stability of the partial denture.

    dimensional stability is measured by digital caliper.

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

A study testing PEEK and Bre.flex in people with Patient Satisfaction, run by Cairo University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

patient satisfaction (time frame: 1 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Feb 2017.
