Many dentists use resin primers and adhesives to prevent post-cementation sensitivity of teeth restored with crowns. However, little information is available regarding the effect of these resins on crown retention. This laboratory study concluded that two popular resins, Gluma Desensitizer (Heraeus Kulzer) and One-Step (Bisco Dental Products), had little or no effect on the retention of crowns luted with zinc phosphate, glass ionomer or resin-modified glass ionomer cements.

Wear investigation of implant-supported upper removable prothesis with electroplated gold or PEKK secondary crowns.
Biomed Tech (Berl)
January 2025
Oral Technology, University of Bonn, Bonn, Germany.
Objectives: The aim of the present study was to investigate, whether polyetherketoneketone (PEKK) secondary crowns could be considered as alternative to gold standard in terms of their physical properties and manufacturing costs.
Methods: An upper jaw model with six implants was used. Frameworks with either 6 PEKK- or 6 electroplated secondary crowns were cemented in a wear simulator.
Evaluation of Retentive Force and Long-Term Performance of 4 Mol% Yttria Partially Stabilized Zirconia (4Y-PSZ) Double Crowns.

Department of Prosthodontics, Graduate School of Dentistry, Showa University, Tokyo, JPN.
Purpose: This study aims to evaluate the effects of taper angle and the number of insertion-removal cycles on the retention force of 4 mol% yttria partially stabilized zirconia (4Y-PSZ) double crowns over time.
Materials And Methods: Primary and secondary crowns were fabricated using 4Y-PSZ with taper angles of 2°, 4°, and 6° (n=15). Retention force during crown removal was measured after applying 50-N and 100-N loads.
Use of a periodontal resective procedure (proximal wedge technique) for treating gingival and periodontal pockets of mandibular canine teeth in dogs.
J Small Anim Pract
January 2025
Cibolo Creek Veterinary Hospital, Boerne, Texas, USA.
Objectives: This study aims to evaluate the ability of a periodontal resective procedure (the Proximal Wedge Technique) to improve the long-term health of the mandibular canines by reducing probing depths immediately post-surgery via targeted tissue recontouring and precise debridement. The technique aims to enhance periodontal health and stabilize the supporting structures of strategically important adjacent canine teeth, including alveolar bone, rather than relying solely on mandibular incisor extractions with simple closure.
Materials And Methods: A retrospective records review compiled data from patients with suprabony pockets of 6 mm or greater at the mesial aspect of the mandibular canines treated with the proximal wedge technique (PWT).
Proper alignment of the teeth not only aids in functional occlusion but also promotes harmonious gingival contours, potentially reducing the risk of inflammation and gingival recession. This case series aimed to evaluate the effectiveness of optimizing axial inclination through clear aligner orthodontic treatment in addressing gingival recession defects. This case series included nine patients, aged 20-36 years, who presented with varying degrees of gingival recession on 12 mandibular incisors.

Sri Ramachandra Medical College and Research Institute, Sri Ramachandra Institute of Higher Education and Research, Chennai, India.
Background: Rotations are frequently evaluated through various assessment methods of crowding and arch dimension, with relatively few studies discussing the extent or direction of rotations and even fewer addressing the reliability of such assessments. This systematic review aims to comprehensively analyze existing classification systems for rotated teeth and assess rotation in anterior and posterior teeth, its clinical applicability, and its impact on retention and relapse.
Search Methods: Two investigators conducted a comprehensive search in six databases, namely, PubMed, Scopus, Ovid, LILACS, Web of Science, and Cochrane CENTRAL, up to 28 March 2024.
