To assess the clinical performance of CAD/CAM monolithic implant-supported restorations manufactured using a fully digital workflow and two different types of ceramic blocks. One hundred and one patients received single-unit implant-supported restorations at a University predoctoral clinic. All restorations were designed and fabricated using either a predrilled LS block (group P, n = 59) or a conventional solid LS block with an occlusal opening drilled manually prior to crystallization (group M, n = 42). The mean follow-up time after restoration delivery was 18.4 ± 4.8 months (range 12 to 33 months). Patients with less than a 12-month follow-up were excluded. Electronic health records were reviewed to identify number and type of complications during the follow-up time. Clinical outcomes were classified as success, survival, and failure of the restoration. Chi-square tests were used to identify differences in success and survival rates between the groups. Nonparametric Mann-Whitney U tests were used to identify differences in the number of major and minor complications as well as the total number of complications that were observed among groups. Overall success and survival rates were 80.2% and 97%, respectively. Seventy one restorations (70.3%) were complication-free. There were no significant differences between the groups with regards to the number of complications or success and survival rates. Single-unit CAD/CAM monolithic implant-supported restorations that are fabricated in a fully digital workflow present relatively high complication rates and moderate short-term clinical outcomes. Clinical studies with longer follow-up times are needed to evaluate long-term outcomes of these restorations.

However, study results are contradictory warranting more investigation in this field. We analysed 19,293 patients of the European Sleep Apnoea Database (ESADA) cohort with restriction to the three predominant climate zones according to the Köppen-Geiger climate classification Cfb (warm temperature, fully humid, warm summer), Csa (warm temperature, summer dry, hot summer), and Dfb (snow, fully humid, warm summer). Average outside temperature values were obtained and several hierarchical regression analyses were performed to investigate the impact of temperature on the apnea-hypopnea index (AHI), oxygen desaturation index (ODI), time of oxygen saturation less then 90% (T90) and minimum oxygen saturation (MinSpO2 ) after controlling for confounders including age, body mass index, gender, and air conditioning (A/C) use. AHI and ODI increased with higher temperatures with a standardised coefficient beta (β) of 0.28 for AHI and 0.25 for ODI, while MinSpO2 decreased with a β of -0.13 (all results p less then .001). When adjusting for climate zones, the temperature effect was only significant in Cfb (AHI β = 0.11) and Dfb (AHI β = 0.08) (Model 1 p less then .001). The presence of A/C (3.9% and 69.3% in Cfab and Csa, respectively) demonstrated only a minor increase in the prediction of the variation (Cfb AHI, R2 +0.003; and Csa AHI, R2 +0.007; both p less then .001). Our present study indicates a limited but consistent influence of environmental temperature on OSA severity and this effect is modulated by climate zones.The trachea is a rigid air duct with some mobility, which comprises the upper region of the respiratory tract and delivers inhaled air to alveoli for gas exchange. During development, the tracheal primordium is first established at the ventral anterior foregut by interaction
