Prognosis for Abutment Teeth of Removable Dentures: A Retrospective Study

Abstract

Removable partial dentures retained by conical crowns have a favorable clinical prognosis.

Electroplated and cast double crown-retained removable dental prostheses: 6-year results from a randomized clinical trial

“…Nearly Table 3 Odds ratios for partial and total facing loss of double crowns after 6 years according to study group and several patient and tooth characteristics C-RDP cast double crown-retained removable dental prosthesis, EP-RDP electroplated double crown-retained removable dental prosthesis, OR odds ratio, CI confidence interval, p probability value from the multiple Cox regression model all of the factors used to interpret the survival of RDP apply to the abutment teeth also. Previous long-term studies [4,8,9,14] and the results of this study showed that abutment tooth loss was not correlated with the type of abutment; the most common reasons for tooth loss were biological complications, for example periodontal disease, caries, and tooth fracture. The lower cumulative survival of abutment teeth in the EP-RDP group (85 %) than in the C-RDP group (91 %)-without reaching statistical significance-may be correlated with the larger number of males in the EP-RDP group.…”

“…Numerous reports are available on the survival of RDP, survival of abutment teeth, and complications of cast double crown-retained RDP [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The current dental literature, however, does not provide sufficient information about the clinical performance of RDP retained by electroplated double crown systems.…”

“…Double crown-retained removable dental prostheses (RDP) have been clinically proven to be a successful treatment option in the prosthetic dentistry [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The versatility and advantages of double crown retainers for RDP have recently been emphasized once again [17].…”

Fabrication of crown restoration retrofitting to existing clasps using CAD/CAM: Fitness accuracy and retentive force

“…Some complications of the clasp, such as clasp-arm breakage, ill fit, decrease of retention, and abutment tooth disease, are frequently observed with long-term use of the RPD [1,2]. If the crown used as the abutment tooth is removed or eliminated because of secondary caries or occurrence of periapical periodontitis, the RPD will be repaired or remade.…”

Long-term behavior of double crown retained dentures with metal and metal-free secondary crowns and frameworks made of Vectris© on all-ceramic primary crowns: a prospective, randomized clinical trial up to 14 years

“…For decades, double crown retained removable dentures have been an approved method for clinical treatment of reduced residual dentition, combining the advantages of fixed with those of removable partial dentures [1][2][3][4][5][6]. Apart from enabling optimal hygiene, double crown retained removable dentures achieve a favorable axial load and suitable fitting of the abutment teeth.…”
