What is an elevator in dentistry?
In dentistry, elevator instruments are used to luxate teeth, and this technique imparts forces to tooth particles that sever the periodontal ligament around tooth roots inside the socket and expand alveolar bone around tooth particles.
What is the difference between a dental elevator and Luxator?
Dental luxators have sharp, flat-tipped blades that can penetrate into the periodontal space. Dental elevators have less sharp, more curved blades that fit the shape of the tooth. Luxating elevators often combine the benefits of the two basic designs.
What is the Mucoperiosteal elevator used for?
This allows the operator to remove the mucoperiosteum from the anterior wall of the sinus with greater ease and certainty. It also allows him to reach easily into the alveolar depressions in the sinus.
What is a root elevator?
Root Elevator. Root elevators are used for surgical tooth extractions. They are used to luxate the tooth in the osseous alveolus and to expand the alveolus walls. They are also used to open the gingival sulcus prior to the tooth extraction. Straight instruments are used in the anterior region and in the maxillary area.
When do you use a Coupland elevator?
Coupland’s elevators (also known as chisels) are instruments commonly used for dental extraction. They are used in sets of three each of increasing size and are used to split multi-rooted teeth and are inserted between the bone and tooth roots and rotated to elevate them out of the sockets.
What are the components of elevator?
Cabin/ Car. This is the main part of Elevator which is designed for enclosed transport of passengers & goods.
Which type of motor is used in elevator?

What is full thickness flap?

What is a bone file?
A rasp or bone file can be used to smooth out the acromial resection. • Attention is paid to the undersurface of the AC joint. • A blunt, double-pronged (Czerny) retractor is extremely useful at this stage.
Which motor is used in elevator?
Why DC motor is used in elevator?
DC cumulative compound motor having high starting torque up to 450% depending upon the degree of compounding. The speed regulation is varying up to 25 ~ 30%. That’s why these motors are used in elevators.
Are elevator motors AC or DC?
Also DC is typically preferred for easier RPM control (like in trains, tramcars, etc) but this is not a problem for elevators – they typically use two-speed three-phase AC motors and speeds are changed by switching the number of poles.
What are the different types of dental elevators?
Dental Elevators classification according to FORM: 1 Straight – Wedge type – straight apex 2 Angular – Right and Left types 3 Cross Bar – Handle is placed at right angle to shank to provide more force with less pressure exerted
What is the principle of a tooth elevator?
Same as socket applicator cross bar elevator – Principle of action is wheel and axel – It is introduced through the empty socket of one root of multi rooted mandibular molar to engage and remove the interseptal bone and the other remaining root 50.

What are the different types of apexo elevators?
The Apexo Elevators are divided into three types depending on their usage – No. 301 straight apexo elevators which are used to remove fractured roots of maxillary central and lateral incisors, premolars and canine. No. 73 and 74 are used for removing impacted maxillary molars thanks to their shank curvature.
