Conventional, Overdenture and Palateless Overdenture Oral Health Impact Comparison Study

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).

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall Patient satisfaction OHIP 49 score
Time Frame: End of initial treatment (32 weeks) after all 4 prostheses have each been worn for 10-12 weeks
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.
End of initial treatment (32 weeks) after all 4 prostheses have each been worn for 10-12 weeks

Secondary Outcome Measures
