About this study

Official title: Evaluation of Patient Satisfaction Comparing Conventional, Overdenture and Palateless Overdenture Using Guided Maxillary Implant Placement

This study will identify and enroll patients already scheduled to receive guided maxillary implant placement with palateless overdenture. Standard clinical practice will be followed for this multi-stage process. The study purpose is to evaluate the degree of satisfaction during the standard progression in order to determine at which post edentulous stage patients achieve maximum satisfaction using the Oral Health Impact Profile 49 (OHIP 49).

Read the detailed description

The OHIP 49 will be administered at pre-treatment (edentulous condition) and after each visit (i.e., newly fabricated conventional denture, conversion to a 4 implant retained overdenture and finally a 4 implant retained palateless overdenture). Additionally they will be recalled yearly for 5 years.

Participants will have an interim denture fabricated to be worn for 10-12 weeks. During this time, participants will have 4 implants placed and continue wearing the interim denture. At 8 weeks after implant placement, participants will have locator attachments placed on implants and the interim denture snapped into place, termed the 'overdenture.' After 10-12 weeks of wearing this overdenture, patients will receive a new denture, termed 'final palateless overdenture,' which consists of a denture snapped into the 4 implants without a palate. Participants will be evaluated at a 10-12 week followup from insertion of this prosthesis. Participants will complete questionnaires at each stage of treatment.

One year after delivery of the final palateless overdenture and for five consecutive years patients will be asked to return for a follow up appointment.

Estimated duration of patient participation is approximately 5 years and 8 months (271 weeks). Estimated time for active clinical treatment is 8 months (32 weeks) with understanding of flexibility based on laboratory fabricated denture frameworks and adjustments needed for approval of esthetics.

What is being measured

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

  1. Overall Patient satisfaction OHIP 49 score

    The OHIP 49 provides a measure of social impact of oral disorders by providing a comprehensive measure of dysfunction, discomfort and disability resulting from oral cavity conditions. The OHIP 49 is based on the adaptation of the World Health Organization classification. Responses on the OHIP 49 questionnaire are made on a patient satisfaction survey consisting of 49 items organized into 5 subscales (not at all satisfied, not very satisfied, reasonably satisfied, very satisfied, totally satisfied) and responses are based on a Likert scale.

    Measured: End of initial treatment (32 weeks) after all 4 prostheses have each been worn for 10-12 weeks

Secondary outcomes (11)
  1. Change in OHIP 49 score of initial edentulous condition to new interim denture

    Participant will wear new denture for 10-12 weeks and then OHIP 49 will be administered to compare satisfaction score to their previous edentulous condition.

    Measured: Initial edentulous condition to 10-12 weeks post insertion of new interim denture

  2. Change in OHIP 49 score of new interim denture to implant retained interim denture

    Participant will wear implant retained denture for 10-12 weeks and then OHIP 49 will be administered to compare satisfaction score to their previous denture without implant retention.

    Measured: Interim denture placement to 10-12 weeks post insertion final palateless implant retained overdenture

  3. Change in OHIP 49 score of final palateless implant retained overdenture

    Participant will wear final palateless implant retained overdenture for 10-12 weeks and then OHIP 49 will be administered to compare satisfaction score to their previous denture without implant retention.

    Measured: 10-12 weeks post insertion of final palateless implant retained overdenture

  4. Change in OHIP 49 score of final palateless implant retained overdenture-Year 1

    Participant will wear final palateless implant retained overdenture for 1 year and then OHIP 49 will be administered to compare satisfaction score to their previous denture without implant retention.

    Measured: 1 Year post insertion of final palateless implant retained overdenture

  5. Change in OHIP 49 score of final palateless implant retained overdenture-Year 2

    Participant will wear final palateless implant retained overdenture for 2 years and then OHIP 49 will be administered to compare satisfaction score to their previous denture without implant retention.

    Measured: 2 Year post insertion of final palateless implant retained overdenture

  6. Change in OHIP 49 score of final palateless implant retained overdenture-Year 3

    Participant will wear final palateless implant retained overdenture for 3 years and then OHIP 49 will be administered to compare satisfaction score to their previous denture without implant retention.

    Measured: 3 Year post insertion of final palateless implant retained overdenture

  7. Change in OHIP 49 score of final palateless implant retained overdenture-Year 4

    Participant will wear final palateless implant retained overdenture for 4 years and then OHIP 49 will be administered to compare satisfaction score to their previous denture without implant retention.

    Measured: 4 Year post insertion of final palateless implant retained overdenture

  8. Change in OHIP 49 score of final palateless implant retained overdenture-Year 5

    Participant will wear final palateless implant retained overdenture for 5 years and then OHIP 49 will be administered to compare satisfaction score to their previous denture without implant retention.

    Measured: 5 Year post insertion of final palateless implant retained overdenture

  9. Number of participants exhibiting soft tissue complications of final palateless implant retained overdenture

    Participant will return yearly for 5 years to evaluate possible complications in regards to health of soft tissue

    Measured: Immediately post insertion of final palateless implant retained overdenture through Year 5

  10. Number of participants exhibiting fit complications of final palateless implant retained overdenture

    Participant will return yearly for 5 years to evaluate possible complications in regards to the fit of the palateless implant retained overdenture

    Measured: Immediately post insertion of final palateless implant retained overdenture through Year 5

  11. Number of participants exhibiting retention complications of final palateless implant retained overdenture

    Participant will return yearly for 5 years to evaluate possible complications in regards to the retention of the palateless implant retained overdenture

    Measured: Immediately post insertion of final palateless implant retained overdenture through Year 5
