About

Comparing patient satisfaction and retention of upper complete denture fabricated using two different denture base materials, the first fabricated using rapid prototyping method while the second is following conventional methods.

Full description

Searching for other materials or other fabrication technologies has been one of the goals to help to re-innovate the fabrication of complete dentures , which would greatly influence completely edentulous Patient satisfaction. The introduction of rapid prototyping (RP)Stereo lithography (SLA) technology has many advantage as high accuracy, high mechanical strength, smooth surface finish with close tolerance and fine details printing, but it has some limitation as it is only limited Material, in addition to the high material and equipment cost.

SLA has been used in dental fields like maxillofacial prosthesis , wax pattern fabrication for crown bridge , removable partial denture 19, but still complete denture was reported in a very few reports indicating that RP is not yet successfully applied in Complete denture manufacturing 19-21A randomised trial is therefore needed to asses accurately wether the introduction of rapid prototyping in complete denture fabrication is successful or not in comparison to the conventional technique and to discover the possible challenges in this recent technique and the ways to overcome it.

Retention of complete dentures and patient satisfaction has been reported in many studies22-26. Patients have showed a higher satisfaction, as retention of both maxillary and mandibular complete dentures increased.
