In various clinical conditions like atrophic or resorbed ridges, xerostomia, dentures opposing natural dentition, bony undercuts, relining is indicated to recapture the fit of the denture base, especially when the denture still retains proper vertical dimension, occlusal relationship and esthetics.2,3. (docksci.com)
Also used in oral cancer patients with postoperative defects requiring obturation and to modify transitional prosthesis after stage I and II implant surgery.4 Denture liners have been used in dentistry for more than a century. (docksci.com)
But the retention will be variable based on the attachments systems selected and the how fitting your denture is to the bar. (drbeatriceleung.ca)
Comparison of cast Ti-Ni alloy clasp retention with conventional removable partial denture clasps. (thejcdp.com)
When a partial denture is placed in the mouth, clasps gently spring over a tooth bulge and rest in a relaxed state within an undercut. (riversidecosmeticdentistry.org)
The traditional lost-wax process remains the major approach used for fabricating dental prostheses, such as full metal crowns, porcelain fused metal (PFM) crowns, pressed ceramic crowns, and removable partial denture (RPD) frameworks. (ommegaonline.org)
Accordingly, the aims of this study were to assess the accuracy of the fit of maxillary complete denture base plates fabricated using a 3DP technique and to evaluate the feasibility of using this technique in the production of wax patterns for removable prostheses. (ommegaonline.org)

Clasp3
Interim Palatal Lift Prostheses Retentive Clasp Assembly Retentive clasp assemblies responsible for securing interim palatal lift prostheses often benefit from the development of exaggerated retentive undercuts. (wikipedia.org)
However, the means by which they are retained in the mouth is different than a conventional clasp prosthesis. (elgindenturedentist.com)
This in vitro study showed that the framework association between cast clasp and an extra resilient attachment are suitable to the three metals evaluated, but strongly suggest extra care with commercially pure titanium in undercut of 0.75 mm. (thejcdp.com)
Retentive5
An interim palatal lift prosthesis generally consists of two or more stainless steel wire retentive clasps embedded in polymethylmethacrylate that adapts to the hard palatal and soft palatal mucosal surfaces and the lingual aspects of the maxillary teeth. (wikipedia.org)
A definitive palatal lift prosthesis generally consists of a thin cast metallic alloy lamina that covers the hard palatal mucosa and the lingual aspects of the maxillary teeth and incorporates retentive clasps that strategically engage undercut dental surfaces to enhance the retentive capacity of the prosthesis. (wikipedia.org)
Alternatively, patients missing enough teeth to compromise the predictable retention of a palatal lift prosthesis may become candidates for the fabrication of a palatal lift prosthesis with the placement of endosseous titanium implants and abutments designed to serve as retentive elements in partially edentulous and edentulous patients. (wikipedia.org)
In dentate patients, these requirements are easily met by relying on the remaining dentition, retentive tissue undercuts, and support areas within the defect. (com.pk)
Frameworks fabricated in Cp Ti tend to decrease in retentive strength over time and have a potential risk of fracture in less than 0.75 mm of undercut. (thejcdp.com)
Stability4
Similarly, partially edentulous patients missing anterior maxillary teeth lack the stability and retention afforded by anterior portions of the palatal lift prosthesis called indirect retainers that appose the lingual aspects of anterior maxillary teeth. (wikipedia.org)
A favorable defect must be designed at the time of tumor removal to provide proper support and sufficient retention and stability of the obturator for the prosthesis to function adequately. (com.pk)
6 , in the search for these objectives, the teeth of complete dentures should ideally have simultaneous contact (balanced occlusion) so as not to compromise the stability and retention of one or both dentures. (bvsalud.org)
Any bar you design will improve the support and stability for your prosthesis. (drbeatriceleung.ca)
Although no algorithm regarding a requisite number of teeth exists for the retention of a palatal lift prosthesis, the possession of a full complement of healthy maxillary teeth offers more assurance of adequate retention than any other factor. (wikipedia.org)
One of the things I never thought about before was the path of insertion for the bar vs the path of the attachments that need to travel to obtain adequate retention. (drbeatriceleung.ca)
Edentulous2
While palatal lift prostheses can be retained by patients exhibiting maxillary partial edentulism, partially edentulous patients without posterior maxillary teeth suitable for the receipt of prosthetic clasps also known as direct retainers enjoy less retentive predictability than patients with maxillary posterior teeth. (wikipedia.org)
When surgical reconstruction is contraindicated because of the presence of residual tumors or the patient's poor physical condition, perform prosthetic rehabilitation of the partially edentulous mandible with a mandibular guidance prosthesis. (medscape.com)
Removable3
However, use of bone graft alone seldom provides an optimal base for removable prostheses. (medscape.com)

However, according to the literature, the application of 3DP in the fabrication of wax patterns for removable prostheses remains rare. (ommegaonline.org)
Conventional2
Roots and dental implants help to preserve bone, and the added retention is known to be greater than conventional complete dentures alone. (medscape.com)
Our findings suggest that attachment-retained RPDs have good retention and better esthetics than conventional RPDs and that the extracoronal attachment system is the most viable choice for treatment at the free end. (bvsalud.org)
Prosthetic3
The objective is to obtain good retention and fit of the prosthetic appliance and balanced occlusion, in perfect harmony with all structures of the masticatory system 4 . (bvsalud.org)

Palatal11
A palatal lift prosthesis is a prosthesis that addresses a condition referred to as palatopharyngeal incompetence. (wikipedia.org)
Palatal lift prostheses are designed to address palatopharyngeal incompetence. (wikipedia.org)
Although structurally similar to palatal lift prostheses, technically distinct soft palatal obturator prostheses or speech aid prostheses are used to address palatopharyngeal insufficiency. (wikipedia.org)
A palatal lift prosthesis addresses palatopharyngeal incompetence by physically displacing the dysfunctional soft palate in the hope of closing the palatopharyngeal port enough to mitigate hypernasal speech and/or prevent nasopharyngeal regurgitation of liquids or solids during the pharyngeal phase of swallowing. (wikipedia.org)
A palatal lift prosthesis consists of an oral component that stabilizes and secures the prosthesis and an oropharyngeal extension that superiorly and posteriorly displaces the impaired soft palate. (wikipedia.org)
Palatal lift prostheses are classified as interim or definitive prostheses. (wikipedia.org)
An interim palatal lift prosthesis carries a current dental terminology code number of D5958. (wikipedia.org)
The cast metallic portion of a definitive palatal lift prosthesis typically harbors a posterior cast metal lattice that retains a polymethylmethacrylate oropharyngeal section of the prosthesis responsible for elevating the soft palate. (wikipedia.org)
Definitive and interim palatal lift prostheses both carry current procedural terminology code numbers of 21083. (wikipedia.org)
Because a mechanically displaced soft palate imparts enough force upon a palatal lift prosthesis to dislodge it, dentoalveolar anatomy must be considered prior to the fabrication of a palatal lift prosthesis. (wikipedia.org)
Removal of more than 50% of the tongue requires construction of a palatal or lingual augmentation prosthesis. (medscape.com)
Clasps2
