Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this crossover clinical study was the evaluation and comparison of masticatory performance and patient satisfaction for patients rehabilitated with conventional heat cured acrylic resin and 3D printed mandibular implant overdentures retained with bar attachment.

it was concluded that 3D printed implant overdenture showed promising results regarding chewing efficiency and patient satisfaction compared to conventionally fabricated implant overdenture.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of this crossover clinical study was the evaluation and comparison of masticatory performance and patient satisfaction for patients rehabilitated with conventional heat cured acrylic resin and 3D printed mandibular implant overdentures retained with bar attachment.

Materials and Methods: Twelve completely edentulous healthy participants received new conventional dentures. Four interforaminal implants were inserted in the mandible. After osseointegration, bar was constructed with trapezoidal configuration. Each patient received randomly the following overdentures using a crossover design: conventional heat cured acrylic resin overdenture, 3d printed overdenture ( developed by scanning of mandibular conventional overdenture). Masticatory performance was evaluated with the two-colour mixing ability test after 5, 10, 20, 30, and 50 masticatory cycles. Patient satisfaction was also measured using McGill Denture Satisfaction Questionnaire. Evaluation was done after 3 months of using each overdenture.

Conclusion: Within this clinical study limitations, 3D printed implant overdenture showed promising results regarding chewing efficiency and patient satisfaction compared to conventionally fabricated implant overdenture.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Each patient received two prostheses; conventional and 3D-printed implant overdentures. The succession of complete denture insertion was randomized to diminish the effect of the order of complete denture use on the results. First, each denture was used for three months, followed by two weeks of rest; then, the other denture type was delivered to the patient and used for another three months.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* adequate bone quantity \[classes 1-3 according to \[Lekholm and Zarb\] of the mandible in the lateral incisor and first premolar regions to receive 4 implants
