How do you use pressure indicator paste?
PIP is applied to the dry denture; companion PIP spray is applied to the tissue. The denture is then seated under pressure then removed. Areas where the paste has been displaced show points of excessive pressure.
How do you get rid of pressure indicating paste?
Pressure Indicator Paste (PIP) Remover has been especially formulated by Mizzy to help you clean PIP from appliances. To remove PIP and other impression materials from skin, dentures, instruments and other surfaces, use PIP Remover on a cloth or swab.
What is pressure indicating paste used for?
Pressure-indicating pastes are used to detect areas of pressure or uneven contact on the mucosa or natural teeth from dentures. Various recipes are used and different methods of application of the pastes, sprays and waxes are described.
What is Lingualized occlusion?
Lingualized occlusion is developed to maintain the food-penetration advantages of the anatomic form while maintaining the mechanical freedom of the nonanatomic form. The lingualized concept utilizes anatomic teeth for the maxillary denture and modified nonanatomic or semi anatomic teeth for the mandibular denture.[3]
Is Lingualized occlusion balanced?
Lingualized occlusion is a compromise between using anatomic and nonanatomic posterior tooth forms. In a nonbalanced set‐up, the dentures may still tip in contact positions other than centric occlusion due to the lack of balancing contacts.
What is the difference between centric relation and centric occlusion?
Centric occlusion refers to a position of maximal, bilateral, balanced contact between the cusps of the maxillary and mandibular arches. Centric relation is the most retruded, unstrained position of the mandibular condyle within the temporomandibular joint (TMJ), that is, within the glenoid fossa.
Is centric occlusion normal?
Unlike centric relation, centric occlusion is independent from the position of the jaw joint. In a few people, centric occlusion equals centric relation. But in many other cases, MIP and CR vary anatomically, which can result in problems.
What does Disclusion mean?
Filters. (dentistry) A separation of the teeth when the jaw is slightly opened. noun. (dentistry) Especially, a separation of posterior teeth when the lower jaw moves forward, as a natural result of the alignment of the anterior teeth.
How do you record centric occlusion?
Gently position the four fingers of each hand on the lower border of the mandible. The little finger should be slightly behind the angle of the mandible. The pads of your fingers should align with the bone and stay together as if you were going to lift the head. Bring the thumbs together to form a C with each hand.
What is Christensen phenomenon?
[C. Christensen, Danish dentist and educator] A gap occurring in the natural dentition or between the opposing posterior flat occlusal rims when the mandible is protruded (posterior open bite). It can lead to instability in full dentures unless compensating curves are incorporated into the dentures.
How can Christensen phenomenon be prevented?
The space that occurred between the upper and lower posterior teeth is called Christensen phenomenon. In order to avoid this phenomenon the curves Spee and Wilson must be constructed.
How do you achieve a balanced occlusion?
-The incisal guidance is usually obtained from patients esthetic and phonetic requirements -The compensating curve is the most important factor in obtaining occlusal balance. – Cusp teeth have the inclines necessary for balanced occlusion but nearly always used with a compensating curve.
Why do we need balanced occlusion?
So, for these 4hrs of tooth contact, balanced occlusion is important to maintain denture stability. It improves the stability of denture, reduce resorption of the residual ridge and soreness and improve oral comfort & well-being of the patient.
What are the theories of occlusion?
Theories of complete denture occlusion Bonwill’s theory(1858) • Theory of equilateral triangle. This theory proposed that teeth move in relation to each other as guided by the condylar controls and the Incisal point.
What is ideal occlusion?
Meaning (n): The relationship existing when all teeth are perfectly placed in the arcades of the jaws and have a normal anatomic relationship to each other. When the teeth are brought into contact the cusp-fossa relationship is considered the most perfect anatomic relationship that can be attained.
Is Class 1 occlusion normal?
It is based on how the maxillary and mandibular first molars come into contact with one another when closing the teeth. The common system used to classify occlusion is termed Angle’s classification system. Class I is considered normal occlusion. Class II and III are considered malocclusion and have different divisions.
