DESCRIPTION
elevators used in dentistryTRANSCRIPT
types of elevators
1.straight elevators : wedge principle.
They are used to displace:
-residual root tips
-supernumerary teeth
-mesiodens
-luxation of the last tooth in the arch mainly the wisdom
Straight apexo elevator : more for anterior lowers
ALL THE ELEVATORS PHOTOS ARE TAKEN FROM THE DENTAL CLINICS AT BAU
Straight London hospital pattern : more for last lower posterior tooth
Coupland chisel elevator : more for anterior lower
Straight warwick james elevator: used in maxilla more than mandible (root tip)
2. curved elevators : lever action.
Mostly used to remove a root tip from its socket.
The elevator engages the tooth through a purchase point ( placed by a bur ) or through gripping the tooth with the edge of the blade and using the bone as a fulcrum to lift the tooth out of the socket.
Curved apexo elevator : called the jocker because of its use on all the teeth ( more for upper)
Used to deliver the remaining roots, if there is more than one root → sectioning .
Also used to deliver upper eight with full crown(used mesio buccaly ).
Curved London hospital pattern: lower remaining roots or for the delivery of the upper wisdom tooth.
Buccal applicator = cryer elevators : contra indicated on maxillary teeth(fear of bone fracture) because it is used buccally and needs a dense bone , used on lower 6,7,and 8 , placed buccaly on the furcation( right and left)
Curved warwick james elevator (root tip) : used on upper eight mesio buccally ,thus, creating space for curved London hospital pattern. ( right or left)
Potts : for upper eight delivery ( right and left)
Root tip pick : may be used on the upper socket , looks like curved apexo elevator but has a longer and thinner blade . to deliver the tip of the roots.
Crane pick elevator : like curved apexo elevator but the blade has no groove.
Socket applicator and upper 8 delivery.
3.T-Bar ( cross bar) right and left: force is 5 tmes applied . wheel and axle mode of action.
The elevator engages a purchase point, using the bone as an fulcrum, rotating the handle.
Indicated for elevating root tips from mandibular molar.
