Ceramic dental filling or onlay is one of the types of non-removable prostheses. Onlays are used for the restoration of premolars and molars (lateral teeth). The dentist will offer this option of prostheses, if the dental defect is too large to perform a filling, however, the volume of dental tissue is sufficient to attach an onlay.
Onlays serve for longer than regular fillings.
Onlay is an option that spares dental tissue. It is mainly used for the restoration of dead teeth, however, onlays can be applied on live teeth as well. Ceramic fillings are harder than regular fillings; they perfectly restore the anatomy of the teeth and contact surfaces between the teeth, as well as evenly distribute the load along the entire surface of the tooth, thus protecting the tooth from the risk of fracture. It is a modern, aesthetic, functional and durable method for the restoration of lateral teeth.
Onlays are a contemporary and durable method of restoring severely damaged lateral teeth without the application of crowns. Onlays are predominantly used for the restoration of teeth after root canal treatment. They enable the return of sufficient chewing function to the teeth thanks to the perfect anatomy thereof. Aesthetically, the restored tooth does not differ from a healthy tooth.
