In dentistry, the drill is called an angled piece . It is used in the patient's mouth to carry out drilling and grinding work. At an angle of 30° to the lower part, rotating instruments can be inserted into the head. This turns a preparation instrument into a series of special instruments for special uses.

Dentrotec spare parts range for angle pieces
Dentrotec supplies gears, rings, segments, sliders and the necessary tools for replacement from proven brand manufacturers in dental technology. Their products fit all common models and are characterized by their durable, hygienic quality:
Head gear
The spare parts for the head gear include collets and ceramic ball bearings. These contra-angle spare parts are color-coded depending on the speed required . Depending on the treatment goal, a green contra-angle with 7,400 min-1 is the slowest. A red contra-angle with 200,000 min-1 is the fastest. The individual components of the head gear are supplied with a ready-to-install, fully assembled head drive and a spring washer.
Intermediate gear
Intermediate drives are delivered fully assembled. You can find the fit in the respective model information for your angle pieces. The bearings in the intermediate gear are characterized by their smooth running and robustness. They should be replaced together with the head drive when repairing an angle piece . This means that the gears of both replacement parts always fit together perfectly.
Snap-on lid
Push-button covers are an important spare part for changing the head gears on angle pieces. They often wear out due to use. Replacement is always necessary when repairing the head drive. Even if the mechanism is jammed, for example after a fall, the push-button cover ensures that all parts of the angle piece mesh together optimally again.
Spring rings and sliders
In the spare parts column for spring rings and sliders you will find a whole range of model information for each item. This means that a spare part can be used for several variants. Instead of ordering individually, you can also purchase the set. Such a set consists of a spring, segment and slider and simplifies the angle piece repair of the head gear. The replacement is carried out using a collet.
Segments and screws
You can find segments and screws at Dentrotec individually or as a practical installation set. These spare parts are designed for installation in the head gear of the contra-angle handpieces. Individual screws are available in slotted or Phillips versions. The size and semi-circular shape of the spare part for segments also fits certain models, for example from KaVo and MK-dent. The exact model names make it easier to select the right segment with screws in the right thread diameter.
Tools for self-repair
The tools for DIY repairs are as diverse as the models of angle pieces. Manufacturers develop the right tool for new workpiece parts. Accordingly, all tools in Dentrotec's range are tailored precisely to the respective model. Examples of tools for repairing angle pieces are keys, clamping tools and opening aids for the lower part of the angle piece.
Ball bearings
High-quality ball bearings reduce differences in the movement of the contra-angle. After a while they wear out and can affect the centering of the head gear. Dentrotec has ceramic ball bearings for all brands in its range for replacement. These contra-angle spare parts are characterized by comparatively low wear and high precision as a component in the contra-angle .

Blue elbow
The normal rotation speed for drills is a maximum of 40,000 rpm and a low gear ratio. For this purpose, the spare part housing is specifically marked as a blue angle piece . Models suitable for angle piece repair are listed in the item description.
