Cumulative effect of digital manufacturing techniques, preparation taper and finish line designs on the retention of aged temporary molar crowns - An in vitro study.

Objective: This study evaluated the effects of finish-line design, tooth preparation taper or total occlusal convergence (TOC), and digital production technology on the retention of provisional crowns for molars.

Material And Methods:  Different taper angles (10° TOC and 20° TOC) and finish line designs (chamfer and shoulder) were used to prepare four mandibular first molar teeth. Two subgroups of the prepared teeth received temporary crowns that were either "Computer-Aided Design" and "Computer-Aided Manufacturing (CAD/CAM) milled or 3D printed.

Assessment of Oral Mucosal Lesions (OML), Periodontal Health Conditions, and Unmet Dental Treatment Needs in the Rural Adult Population of Jharkhand, North India.

Background Dental diseases like caries, periodontal diseases, and oral mucosal lesions (OML) are common findings in rural adult populations that greatly impact their quality of life. Aim To assess OML, periodontal health conditions, and unmet dental treatment needs in the rural adult population in Jharkhand. Methodology A total of 700 permanent residents of Bero Block, Jharkhand, North India, in the age group of 35-44 years, participated in this cross-sectional study.

Radiographic Evaluation of the Gap between Cemented Post and Remaining Gutta-Percha in Endodontically Treated Teeth Performed by Undergraduate Students: A Retrospective Cross-Sectional Study.

The coronal seal in root canal-treated teeth may be compromised depending on the accuracy of post space preparation and post cementation along with remaining gutta-percha. Root canal treatment can be compromised by endotoxins released by the coronal bacteria as a result of microleakage. The study was conducted by undergraduate students to measure the gap between the cemented post and residual gutta-percha.

Comprehensive Rehabilitation of Partially Amputated Index Finger with Silicone Prosthesis: A Case Report with 3 years of Follow Up.

The loss of all or part of a finger following traumatic amputation may have a negative impact on physical and psychological well-being. An esthetic prosthesis can offer psychological, functional, and rehabilitative advantages. One of the major problems associated with somato-prosthetic replacement of partially amputated finger is inadequate retention of the prosthesis.

Replacement of missing anterior tooth using screw retained implant prosthesis in the esthetic zone: a case report with 3 years of follow up.

As more and more dental practitioners are focusing on implant-supported fixed restorations, some clinicians favor the use of cement retained restorations while others consider screw-retained prosthesis to be the best choice. As both types of prostheses have certain advantages and disadvantages, clinicians should be aware of the limitations of each type. Screw-retained implant restorations have an advantage of predictable retention, retrievability and lack of potentially retained sub-gingival cement.

Spring-loaded custom tray: an alternative technique for recording impressions in a patient with a restricted mouth opening.

For patients with extensive head and neck injuries due to trauma and/or extensive surgical procedures, their ability to open the mouth is severely limited. Prosthodontic treatment of these patients often leads to compromised impressions and prostheses. When making an impression, a wide mouth opening is necessary to ensure both proper tray insertion and the correct alignment during border molding procedures.

An innovative technique to restore velopharyngeal incompetency for a patient with cleft lip and palate.

Treatment of cleft lip and palate patients often demand well-coordinated work of medical and dental specialists. In spite of surgical and orthodontic therapy, prosthetic rehabilitation is always necessary because of partial anadontia, maxillary hypoplasia and velopharyngeal dysfuction. The aim of the prosthetic treatment is to improve aesthetics, function and speech of the patients; however, factors like underdeveloped and collapsed maxillary arch, retrognathic maxilla and reduced alveolar ridge height make the treatment challenging.
