Key legal question
Whether compulsory health insurance must cover the planned dental treatment under Art. 31 KVG and related ordinances.
Extracted holding
Coverage was not owed because the dental disease was deemed preventable through adequate oral hygiene and regular dental controls.
Extracted reasoning
Only non-preventable diseases of the chewing system caused by a serious general illness trigger mandatory benefits. The evidence showed no proven xerostomia or medication-related direct cause, and the lesions were considered avoidable by timely preventive care.
