Hooks In 4 min EX: 18
Ajoutée le 23 févr. 2019
the hooks: After the aesthetic and functional fitting, hooks are made with a thread in steel half-ring on the teeth bordering edentation to allow the retention of the prosthesis
after polymerization. The flat part of the wire is plated on the tooth and the rounded part is in look at the cheeks and lips.
After drawing the line of the largest contour on the tooth, trace the path of the hook which is:
proximal level: on the line of the largest contour
vestibular level: it is above the line of the largest contour in the
half of the tooth next to the toothlessness, it crosses the line of the larger outline
in the middle of the tooth and then passes below the line of the larger outline while
while remaining
parallel on the:
of the tooth that ensures
thus retention.
The hook must never:
touch the marginal gum
it passes from the proximal face of the tooth to the lingual side of the ridge
or palate without touching the lingual surface of the tooth. At about 5mm from the collar, it shows a 90 ° angle to become parallel to the ridge while remaining distant for
do not interfere with prosthetic teeth during assembly. a loop allows to increase its retention in the resin of the base
prosthetic
Immediate PAPR
The specificity of the immediate PAPR lies in the fact that it proposes to
replace the teeth on the day of their extraction to avoid aesthetic inconveniences and
psychological. The mounting of the teeth and the
polymerization of the prosthesis are performed before extraction of the teeth to be replaced and installation
is done right after the extraction.
Clinical examination
- Max and man's fingerprinting
- The recording of inter-max ratio and mounting of models on articulator or
occluder
- The choice of teeth
- The preparation of the working model.
- The realization and the installation of the hooks
- Polymerization
- Extraction of teeth
- Installation of the prosthesis.
- Controls
Transient PAPR
The transitional prosthesis ensures "gentle" passage of edentation
partial to total edentulism with objectives:
- to ensure the replacement of each tooth extracted in the chosen position.
Adding teeth to the existing prosthesis requires:
- The PAP located in the mouth, an impression is made with alginate
- After disinsertion, the good positioning of the PAP in
the impression is verified
- The undercuts of the prosthetic intrados are filled by
addition of wax or silicone of high viscosity in order to
Easily remove the PAP.
- These are deleted, and taking into account the state
periodontal resection, gingival bone resection is prefigured on the
plaster model
- The resin base is frosted next to the teeth to be replaced
- The teeth to be replaced are located thanks to the vestibular key
- The installation of the prosthesis is realization.
