Comparison of the Dimensional Accuracy of Injection‐Molded Denture Base Materials to that of Conventional Pressure‐Pack Acrylic Resin

Abstract

Processing the denture base materials produced unequal deformation in different dimensions (anterior-posterior and cross-arch). Each material tested also responded differently to the processing stages.

Midline Fractures in Single Maxillary Complete Acrylic vs Flexible Dentures

“…Another problem faced with the material was that no repair or relining is feasible.The flexible dentures were found kind to underlying soft tissues. There was no denture sore-mouth and the better comfort level was attributable to low modulus of elasticity [12,16]. Being a subjective analysis few patients were not able to comment on comfort level, phonetics etc and the same has not been included in the result.…”

“…Since we provided flexible maxillary dentures, the present study can be considered as a case control study. Parvizi et al [16] compared the dimensional accuracy between injection molded dentures base material versus poly methyl methacrylate. They were of opinion that injection moulded dentures base material is superior in accuracy.…”

Analysis on the Pattern of Using the Service of Removable Partial Denture Making in a Dental Laboratory in Surabaya

“…This material is very flexible so restoration can move with constant and easy installation in the mouth. This material is also extremely biocompatible (Negrutiu 2005, Phoenix 2004, Keenan, 2003, Parvizi 2004. …”

Viabilitas sel fibroblas BHK-21 pada permukaan resin akrilik rapid heat cured (Viability of fibroblast BHK-21 cells to the surface of rapid heat cured acrylic resins)

“…1 Material ini mempunyai beberapa keunggulan antara lain estetik yang baik, kekuatan tinggi, menyerap air rendah, daya larut rendah, mudah dilakukan reparasi, proses manipulasi mudah karena tidak memerlukan peralatan rumit. 2 Oleh karena itu resin akrilik masih menjadi pilihan utama dokter gigi sebagai pembuatan basis gigi tiruan lepasan, meskipun saat ini telah banyak digunakan material logam campur sebagai basis gigi tiruan lepasan.…”

“…8 Kekurangan material resin akrilik adalah bersifat toksik. 2 Metode kultur sel sering digunakan untuk pengujian efek biologi pada tingkat awal dari suatu material yang digunakan pada kedokteran gigi untuk mengetahui efek toksisitas. 8,9 Sel fibroblast BHK-21 adalah sel yang paling banyak digunakan para peneliti untuk uji toksisitas material di bidang kedokteran gigi.…”
