Monoblock

Monoblock is a term used across engineering and design to describe a unit formed as a single, solid block or module. The meaning emphasizes monolithic integrity, with contiguous parts often sharing a single housing or body to reduce interfaces and improve rigidity.

In audio equipment, a monoblock amplifier (or mono-block) is a power amplifier designed to serve a single channel. By using a dedicated power supply and output stage for each channel, monoblocks aim to minimize interchannel interaction and improve channel separation, at the expense of size and cost. They are often paired to form a high‑fidelity stereo or multichannel system.

In dentistry, a monoblock implant describes a one‑piece implant design in which the main body and the prosthetic abutment are formed as a single unit. This arrangement reduces the number of connections and interfaces, potentially simplifying placement and maintenance, but may constrain prosthetic angulation and retrievability.

In construction and manufacturing, monoblock refers to components produced as a single piece, such as monolithic blocks, castings, or enclosures. The approach can enhance strength, reduce assembly steps, and improve durability, but may require larger tooling, transport challenges, and limited customization.

Other uses include marketing terms for all‑in‑one devices and historical references to single‑piece architectural blocks.
