                                Maxillofacial prosthetic rehabilitation: a survey on the quality of life
5 represented a positive appreciation. The questions were evaluated by lay people who identified no confusing or unclear questions and indicated no apparent need for reduction in items. Overall satisfaction was based on 12 questions on the 5-point Likert rating scale that inquired after the feel of the prosthetic material; junction of the prostheses to surrounding soft tissue, whether making facial expressions or not; similarity in color of skin, tendency to discoloration; shape of the prostheses; and obtained facial symmetry.
Daily prosthetic use was evaluated by 23 multiple choice questions inventorying how
many hours and on which occasions the prosthesis was worn and identifying potential
wear and durability by obtaining information on personal experiences, reasons for replacement, decrease in retention, and loss of superstructures or implants. User
friendliness with regard to placing and removing of the prostheses was determined
by 3 questions on the 5-point Likert rating scale and anchor terms. Twelve multiple
choice questions focused on socialization by determining the level of functioning, self-
esteem, body image, sexual role, and interference in social and job activities. 5
Patients could complement their responses with specific time spans and numbers, possible reasons for prosthetic replacement, and their general opinions and recommendations. Furthermore, 2 multiple choice and 2 open-ended questions asked patients who had previously worn adhesive-retained prostheses about differences between implant- and adhesive-retained prostheses with regard to quality of retention, ease of (daily) use, cleaning regimen, and varying time lengths till wear occurred.
All questionnaires were sent with an accompanying letter explaining the objectives and confidentiality of the study, asking patients to participate, and obtaining informed consent. A stamped, self-addressed envelope for return of the questionnaire was included.
Fisher exact tests were used to assess the difference in proportions between groups. Patient satisfaction scores for each question were statistically analyzed by 2-way analysis of variance (ANOVA) with type of defect and type of retention as factors (no interaction) (α=.05).
