Implant Supported Telescopic Overdenture Clinical Trial
Official title:
Patient Satisfaction and Retention in Cast Metal Versus 3D Printed Metal Copings in Implant Supported Mandibular Telescopic Overdenture
Implant retained overdentures provided more satisfaction with regard to conventional denture
related problems such as esthetics, speech, chewing, fit and retention, function and quality
of life. Evaluation of patient satisfaction allows direct quantification of patients'
opinions on different aspects of a given treatment.
Studies have indicated that conventional complete denture wearers rehabilitated with
mandibular implant supported overdenture experience better retention and stability, improved
overall function and satisfaction.
Patient satisfaction is one factor that influences the success of overdenture
treatment(Naert, Alsaadi et al. 2004). Previous studies have shown a difference between
patients' satisfaction with their dental prostheses and clinicians' assessments of patients'
oral condition.(Emami, Heydecke et al. 2009).This indicates that clinical assessments of
dentures are not valid predictors of patient satisfaction.
The two primary methods used to fabricate these restorations may be subtractive (milling and
grinding) or additive manufacturing (Rapid Prototype, RP or 3D printing), The 3D printing
technology has been incorporated into dentistry, but does not include ceramics and is limited
to polymers.
3D printing by rapid prototyping has many advantages which are the availability of high
production rate where the technician can easily produce over 150 units per hour. Also the
quality control of wax copings which results in high precision fit and constant wall
thickness. This will result in better stability and retention and consequently patient
satisfaction. Finally is the reduced finishing work needed on cast copings. The
irregularities in wax coping thickness can be avoided.

| Primary | Patient Satisfaction | Patients will be recalled on their scheduled dates to the Prosthodontics department ,Faculty of Dentistry , Cairo University. The patient-based outcomes that will be used in this thesis included the variables measured on the 100-mm VAS (Visual Analogue Scale) and on Category Scales (CAT) that had been previously validated | 3 months | |
| Secondary | Retention | small perpendicular metal tubes were placed a few millimetres underneath the canines in the mandibular denture base. In this manner the denture could be rigidly and reproducibly connected to the retention-measuring device. Retention measuring device is a device that was developed to apply an increasing, vertical force on the denture The force was administered througha straight metal bar that was fitted withstrain gauges (Measurements Group Inc.,Raleigh, NC, USA). The bar was rigidly connected to the denture. |
