Clinical evaluation of failures in removable partial dentures

Abstract

The aim of this clinical study was to evaluate the effects of removable partial dentures on the support tissues and changes occurring in lower tooth-supported and bilateral distal-extension dentures, 5 years after placement. The study involved analysis of a total of 53 patients who received prosthetic treatment for removable partial dentures. The patients were divided into two groups. In group 1, the patients had a completely edentulous maxilla and an edentulous area with natural teeth remaining in both the anterior and posterior regions. In group 2, the patients had a completely edentulous maxilla and partially edentulous mandible with preserved anterior teeth. Tooth mobility, prevalence of caries, fracture of the abutment teeth, fracture and/or deformation of the removable partial denture components and stability of the denture base were evaluated. The use of a removable partial denture increased tooth mobility, reduced the prevalence of caries, and did not cause loss or fracture of the abutments or damage to their components, when compared with the baseline. It was concluded that there was no difference between the groups as evaluated in terms of tooth mobility, prevalence of caries, loss and fracture of the abutments or damage to the components of the removable partial denture.

Removable Partial Denture Designing: Variation of Hard and Soft Tissue Anatomy and Maxillary Major Connector Selection

“…In a study done by Janaina et al, it was concluded that RPDs en-OPEN ACCESS http://scidoc.org/IJDOS.php hanced tooth mobility, diminished prevalence of caries and did not induce the fractures of abutments [62]. For RPDs longevity and improve periodontal health in RPDs' users, satisfactory and regular oral hygiene conditions checkups were required [17].…”

Gigi Tiruan Sebagian Kerangka Logam sebagai Penunjang Kesehatan Jaringan Periodontal

“…6,7 Berbagai penelitian telah dilakukan untuk mengetahui pengaruh gigi tiruan sebagian lepasan pada kesehatan periodontal yang terdiri dari akumulasi plak, peradangan gingiva, mobilitas, kedalaman poket dan resopsi tulang. 4,6,8 Disain kerangka gigi tiruan sebagian lepasan dapat meningkatkan penumpukan sisa makanan pada bagian yang berkontak dengan permukaan gigi asli, yang mengganggu aksi self-cleansing oleh lidah dan bukal selama proses pengunyahan. 9 Disain kerangka gigi tiruan sebagian lepasan juga berperan dalam perkembangan bakteri pada rongga mulut dan pembentukan plak.…”

“…14 Benson pada tahun 1979 menunjukkan bahwa tipe I-bar gigi tiruan sebagian lepasan dapat dimanfaatkan oleh banyak pasien dengan sedikit atau tanpa efek yang merugikan pada kesehatan periodontal. 8 Permasalahan lain dari disain gigi tiruan sebagian lepasan adalah menentukan jumlah gigi penyangga yang akan digunakan. 5,6,19 Meningkatkan dukungan periodontal dapat diperoleh dengan jumlah yang lebih banyak dari gigi penyangga yang digunakan.…”

a‐SiOx Coatings Grown on Dental Materials by PECVD: Compositional Analysis and Preliminary Investigation of Biocompatibility Improvements

“…Several types of ceramics and microcomposite resins are used for such a task; however while ceramics are usually materials of well-known high physical and chemical stability, some concerns have arisen in the past about the biocompatibility and stability of microcomposite resins. [4][5][6] These materials are obtained by the polymerization of a resin (usually bis-GMA monomers or some bis-GMA analog, plus a photoinitiator and dimethacrylates) with a filler (silica), [4] and some studies underscored the possibility of toxic or allergenic effects due to the release of monomers as a result of an incomplete polymerization process. [4][5][6] Moreover, even when these materials are well polymerized, they could receive some benefit from a protective layer, since this could reduce or prevent their degradation in the mouth environment.…”

Among the many coating materials studied for the broader field of medical prostheses, several candidates showed good properties of biocompatibility and could be considered virtually promising as barrier coatings in dental applications.…”
