Rehabilitation of a patient with single tooth present on either side of edentulous arch can be done by various methods. But sometimes the patient is not willing to undergo time-consuming procedures of endodontics and fabricated prosthesis on the retained teeth, or the patient is medically compromised so that extraction of the tooth is not indicated. This report describes a novel technique for the fabrication of a complete denture by incorporating prefabricated stainless steel crowns in the denture, which will cover the retained teeth in the upper arch and will also aid in retention of the denture. An acrylic resin removable denture is fabricated. The stainless steel crowns are retained into the denture using molar band, which is soldered to the crowns and extensions are incorporated in the denture resin. The entire technique is inexpensive, helps in retaining teeth and demands less skill compared to semi-precision and precision attachments.
Attachment Retained Cast Partial Denture Prosthesis
abutment is best provided with a clasp or adhesive attachments. 1 Although survival rate of the vital tooth as a telescopic abutment in retaining removable dental prostheses is 89%, root canal treatment increases the risk factor of abutment loss 2 and the visible component of clasp jeopardizes the esthetics. 3 When literature is reviewed retrospectively, survival of attachment retained partial denture shows 83.3% for 5 years, 67.3% up to 15 years and of 50% when extrapolated to 20 years. 4,5 Hence, when the removable dental prostheses are fabricated with precision/semi-precision attachments for retention and support, they are believed to be the best prosthesis available to dentistry especially in conditions where fixed restorations are contraindicated. 6 Retention of the denture prostheses can also be increased using attachments. A RPD with a retained attachment system is one of the treatment modalities which may assist the prosthodontist to achieve the goals of successful restoration.
Attachment Retained Cast Partial Denture: Conventional and Contemporary Treatment Perspectives
International Journal of Oral Care & Research, 2016
Multiple missing teeth situation always claims careful attention and meticulous treatment planning. It becomes more challenging when unilateral or bilateral distal extension situation exists. Successful treatment can be done with some contemporary and conventional treatment planning. Implant-assisted prosthodontics has become contemporary choice of the replacement of the natural teeth, although conventional methods of fabrication of the removable partial denture continue to be an essential prosthetic consideration in many oral reconstructions, especially when implant therapy may not be used to replace missing natural teeth for some patients. Attachment retained partial denture has paved the way for such cases in prosthodontics. Attachment retained partial dentures last longer, wear less, need less adjustments, look better, work better, less destructive, protect abutment teeth, and are easier to clean. In this case report patient's esthetic and functional requirements were fulfilled with attachment retained cast partial denture using semi-precision attachments.
Cast Partial Denture Retained Using Precision Attachment – A Case Report
IOSR Journal of Dental and Medical Sciences, 2016
The most challenging job for a prosthodontist is to rehabilitate the partial edentulous patient especially distal extension cases where fabrication of fixed prosthesis is quite impossible without using implants. Several conventional and contemporary treatment options were available for treating long span edentulous situations. For such cases ,attachment retained cast partial dentures would be the best solution as they give economically, functionally as well as esthetically good results. This article provides a simplified approach for rehabilitating the partially edentulous situations using precision attachment via case report.

Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when unilateral or bilateral posterior segment of teeth is missing. Successful restoration can be done with various conventional and contemporary treatment options. One such treatment modality is attachment-retained cast partial dentures. This paper describes a case report of a patient with mandibular bilateral distal extension edentulous span restored with a cast partial denture having an extracoronal castable precision attachment (RHEIN 83 OT CAP attachments system).

Simplified treatment of severe dental erosion with ultrathin CAD-CAM composite occlusal veneers and anterior bilaminar veneers, 2016
sciencedirect.com Simplified treatment of severe dental erosion with ultrathin CAD-CAM composite occlusal veneers and anterior bilaminar veneers Luís Henrique Schlichting, Tayane Holz Resende, Kátia Rodrigues Reis, Pascal Magne The Journal of prosthetic dentistry 116 (4), 474-482, 2016 Restorative treatment for patients with dental erosion requires an analysis of the degree of structural damage. Patients affected by moderate to severe dental erosion are particularly challenging because complex occlusal reconstruction will be needed. Ultrathin bonded occlusal veneers represent a conservative alternative to traditional onlays and complete coverage crowns for the treatment of severe erosion. This article describes a complete mouth rehabilitation with ultrathin computer-aided design and computer-aided manufacturing (CAD-CAM) composite resin occlusal veneers in a patient with a severely eroded dentition. In the maxillary anterior teeth, the bilaminar approach was chosen with lingual composite resin veneers and labial porcelain veneers. The main benefit of this approach is the possibility of using additive adhesive techniques, allowing only strategic reduction of sound dental structure or no preparation.

Prosthodontic rehabilitation of a patient with terminal dentition is very challenging. Any conservative treatment that can delay or eliminate future prosthodontic problems should be considered. Complete and partially edentulous patients are generally unsatisfied due to the inherent instability of dentures during functional and parafunctional movements which results due to the lack of adequate supporting hard and soft tissues. Inspite of rapid development and good success rate in the field of implantology, preservation of remaining natural teeth or roots is more desirable which supports Devan's dictum. Overdenture is a complete or partial denture prosthesis supported partly by soft tissues and partly by retained natural teeth or its roots or implants. Overdenture increases the retention, stability and support, improves the masticatory efficiency, preserves the alveolar bone and muscular patterns and preserves sensory receptors within the periodontal ligament which increases manipulative skills in handling the denture. Retention and stability of overdentures can be improved by attachments or magnets. Fixed partial denture is not an option when there is no distal abutment. The solution of such a critical situation is to give combined or hybrid prosthesis. A combined prosthesis carries the advantage of fixed removable prostheses without surgical intervention, where an acrylic prosthesis is retained with an extra coronal attachment to tooth. This paper presents a twin patient report of rehabilitation of a mandibular and maxillary terminal dentition with a combined prostheses of acrylic retained by extra coronal precision attachment system (Rhein 83, Italy).
Computer-aided design and computer-assisted manufacturing in prosthetic implant dentistry

The aim of this systematic review was to evaluate the existing scientific evidence on human clinical studies describing the application of computer-aided design/computer-assisted manufacturing (CAD/CAM) technology in restorative implant dentistry. Materials and Methods: Electronic searches for clinical studies from 1966 through May 2008 focusing on long-term follow-up were performed using the PubMed search engine. Concentrating on the restorative aspect of the CAD/CAM technology applicable to implant dentistry, pertinent literature was divided into articles related to implant abutments and implant frameworks. Results: Of the 885 articles initially reviewed, 5 articles (3 CAD/CAM framework and 2 CAD/CAM abutment) satisfied the search criteria of the literature search performed. Combining the results from the framework clinical trial studies, there were a total of 189 prostheses supported by 888 implants. The follow-up varied between 12 and 60 months. Four implants were lost prior to the insertion of the prosthesis and 46 after the insertion. One prosthesis failure was reported. Similarly, in the 2 abutment clinical trial studies there were a total of 53 ceramic abutments supported by 53 implants. The patients were followed between 12 and 44 months. No significant failures or complications were reported in association with the implants and their restorations. Conclusions: Based on a systematic review of literature concerning CAD/CAM used for fabrication of frameworks and abutments, preliminary proof of concept was established. Clinical studies on the use of these techniques were too preliminary and underpowered to provide meaningful conclusions regarding the performance of these abutments/frameworks.
