the aim of this study was to determine the effect of trenched zirconia bar on the von mises stress distribution of ips -empress ii core ceramics.the three-dimensional model including a three-unit bridge from the second premolar to the second molar was designed. the model was reinforced with zirconia bar (zb), zirconia bar with vertical trench (vzb) and zirconia bar with horizontal trench (hzb) ...

statement of problem: targis restorations provide good esthetic and clinical success; however, improving marginal accuracy requires further investigations. purpose: the aim of this was to study evaluate the effect of relining on the marginal accuracy of ceromer crowns. material and methods: one ivorine maxillary central incisor was prepared for targis crown. 10 acrylic models were duplicated fr...

Generally there are three treatment options for replacing missing anterior teeth: removable partial dentures, fixed bridge, and dental implant. To varying degrees, all three options restore chewing function, and provide more normal speaking ability. They also prevent existing teeth from shifting and improve the look of an incomplete smile. The advantages and disadvantages of each of these solut...

The fabrication of an obturator prosthesis is crucial for the closure partial Maxillectomy defects caused by Post COVID Mucormycosis as it improves speech, appearance, acceptability due to better mastication without nasal regurgitation, and overall health status quality life patient. Patients who cannot undergo fixed prosthetic rehabilitation using implants may benefit from attachment retained ...

UNLABELLED Most removable partial denture (RPD) wearers are satisfied with their prostheses, but the factors that influence satisfaction and acceptance are still not determined. OBJECTIVE This study explored technical, biological, and satisfaction variables for the functioning of RPDs after five years, and compared the evaluation by the patient and by the clinician. MATERIAL AND METHODS Fif...

For patients with shortened dental arches, many treatment options are available. The existing situation can be maintained by stabilizing the present dentition and improving the occlusion without extending the arch. Alternatively, the shortened dental arch can be extended by either a free-end saddle removable partial denture, cantilevered fixed bridge, or by an implant-supported prosthesis. The ...

Dental prosthesis is a foreign body in oral cavity and thus necessarily interferes with speech articulation. The purpose of this study was to examine influence of partial denture on speech quality and to show eventual differences in pronunciation of dental sounds c[ts], z [z], s [s] and postalveolar sounds c [t], z [3] and s [integral of]. We have examined differences in pronunciation between s...

The technique in this article was developed to provide a means to create prepared guide planes of proper dimension to ensure a more stable and retentive removable partial denture prosthesis (RPDP) framework when providing this service for a patient. Using commonly found clinical materials, a paralleling device can be fabricated from the modified diagnostic cast of the patient's dental arch requ...

CONTEXT AND AIMS Long span is seen in many clinical situations; treatment planning options of these cases are difficult and may require: Fixed partial denture (FPD), removable partial denture, or implant supported prostheses. Each option has its own disadvantages: Mechanical, patient relief, and cost, respectively. This article will evaluate the stress distribution of another treatment option, ...
