The insertion of chair-side fabricated monolithic lithium disilicate crowns can be recommended for long-term use in the posterior region.

Increasing obesity rates in Swiss HIV+ persons may partially be due to aging, demographic changes and earlier ART start. Most BMI increase occurred in year 1 of ART. The effect of individual ART regimens was limited.

The chair-side application of monolithic lithium disilicate crowns can be recommended.

The aim of this study was to compare the clinical properties of tooth-colored computer-aided design/computer-aided manufacturing (CAD/CAM) materials for the fabrication of a 3-unit fixed dental prostheses (FDPs) in the same clinical scenario. A 53-year-old female patient was supplied with a 3-unit FDP to replace a second premolar in the upper jaw. Restorations were fabricated from 3 mol%, 4 mol%, and 5 mol% yttrium oxide zirconia, zirconia with translucency gradient, indirect composite resin, polyetheretherketone (PEEK), and polyetherketoneketone (PEKK). Milling time, weight, and radiopacity were investigated. Esthetics were examined following the US Public Health Service criteria (USPHS). The milling time for zirconia was twice as high as for the indirect composite resin, PEEK, or PEKK. The latter materials had a weight of 2 g each, while zirconia restorations yielded 5 g. Zirconia presented intense radiopacity. PEEK and PEKK required veneering and an opaquer was applied to the PEKK framework. All FDPs showed acceptable esthetics. PEEK and PEKK restorations were featured by a grayish shimmering. A variety of CAD/CAM materials are available to fabricate 3-unit FDPs with esthetically acceptable results. In the esthetic zone, PEEK and PEKK require veneering and an opaquer might be applied. Milling time, weight, and radiopacity were relatively high for zirconia FDPs.

Background Prevalence values for symptoms and signs of temporomandibular disorders (TMD) in adolescents vary within the literature due to differences in set‐ups of examination protocols. Objectives The objective was to present prevalence values for symptoms and signs of TMD in German adolescents that were observed within a standardised examination. Prevalence values comparing gender or pubertal status should be investigated. Methods A cross‐sectional sample of the LIFE Child Study aged 10 to 18 was examined. A questionnaire gathering anamnestic symptoms of TMD was completed, and an examination according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) was performed by trained dentists. Pubertal status according to Tanner stages was documented. Descriptive statistics, Mann‐Whitney U and Wilcoxon signed‐rank tests were performed. Results A total of 1.116 participants (mean age 12.9 years, 51.4% female) were consecutively recruited. Most prevalent anamnestic symptoms were headaches (55.7%) and temporomandibular joint (TMJ) sounds (17.6%). The major clinical sign was TMJ sounds (31.9%). Both the examination of muscles or TMJs showed that pain to palpation was statistically significantly higher than familiar pain (P < .001). Gender comparisons revealed higher prevalence values and an increase in TMD symptoms and signs during pubertal development in females. Conclusion The prevalence of self‐reported headaches, as well as anamnestic and clinical TMJ sounds, was high in German adolescents. Prevalence values for pain to palpation and familiar pain obtained relevant differences. Considering the DC/TMD, females are more affected by TMD signs and symptoms that increase during pubertal development, than male adolescents.
