HANEL
The Fine Difference Detecting occlusal interferences under any circumstances Occlusal testing and correction are very demanding techniques in modern dentistry. Occlusal interference may cause impairments leading to damaged teeth and pain for the patient. To avoid occlusal interference even the smallest high spots have to be traced.
The HANEL line offers a wide range of products for occlusal testing which will mark effectively and reliably in different conditions and on different materials in the dental practice and in the laboratory. The materials have the correct thickness, elasticity, tensile strength and colour required by dentists for their gnathological work when locating pinpoint, surface or linear contacts, stops and microcontacts. To complement the different test materials, HANEL also offers a range of accessories to make handling even easier.
NEGATIVE EFFECTS OF OCCLUSAL INTERFERENCES ON PATIENTS Almost every tooth modification, e.g. a restoration, extraction or orthodontic treatment changes the static and dynamic occlusion. Just a few microns interference disturbs the proprioreceptors of the stomatological system. This can result in bruxism, a clenching or g rinding, which can cause functional disorder of the craniomandibular system. The effect of this can be overstraining of the periodontium, teeth, muscles and joints. This is the reason why it is very important to detect and avoid functional disorder in the craniomandibular system. Patients whose complaint is typical craniomandibular dysfunction symptoms should undergo a s pecific e xamination of their occlusion, especially when a new filling, crown or bridge was recently placed. Premature contact points are very uncomfortable for the patient, because the proprioceptors react sensibly under pressure and the patient wants to compensate for the occlusal interference by adapting a new habitual position, which can have negative effects for the attached tissue structure.
In our experience the following color/material combinations can be reco mmended: Gold
blue
Porcelain
blue
Amalgam
green/red
Composites blue/red Blue foil is best used on particularly shiny surfaces (Gold, Porcelain) because of its contrast to the flesh colored soft tissue. To combine the HANEL Articulating paper 200 μ with the HANEL Occlusion foil 12 μ offers great advantages on occlusal surfaces. The HANEL Articulating papers work with the principle of the progressive color transmission. That means that areas with a light marking are not necessarily an occlusal contact. But areas marked with a deep dark marking show an occlusal contact. The concrete contact point is in surrounded by the dark color, but the point itself is marked very light only.
Representation of occlusal contacts obtained with different thicknesses of test materials:
200 μ Paper Thick test material. Areas of high pressure cause larger marks.
12 μ Foil Fine test material for pinpoint marking of high spots
40 μ and 80 μ Paper Medium fine test material
High pressure Low pressure (Premature contact) (Normal contact)
ARTICULATING PAPER Use HANEL Articulating Paper 200 μ to examine the o cclusion with progressive color transmission. The HANEL Articulating Paper 200 μ marks large contact areas under pressure and show different pressure forces. It is the best choice to check static occlusion and marks well on all surface conditions.
ST 1 STEP The first test can be done with a HANEL Articulating paper 200 μ with blue color, which transforms the blue c olor p igments to the contact surface of the tooth. Contact areas are immediately visible.

For medium fine testing
› Allows for a quick overview of the occlusal contact situation › Progressive markings: the lower the masticatory pressure, the lighter the marking and vice versa › Available as strips in a practical dispenser box › Occlusal adjustment is simplified by the progressive markings
Available on rolls, or I-, C- and U-form sheets for easy, quick and precise marking. The use of tweezers is not necessary. › Double sided colored › Available in one or two colors › Deep color for good marking

OCCLUSION FOIL Find fine contact points using HANEL Occlusion foil 12 μ. HANEL Occlusion foil 12 μ marks on almost all impact forces and marks pinpoint contacts and high spots precisely. It is the optimal choice to check static and dynamic occlusion.
ND 2 STEP The s econd step is to take a thin HANEL occlusion foil 12 μ, preferably red, which offers high intensity and an excellent contrast to blue color of the HANEL Articulating paper. The color of the foil will mark pin point contacts and high spots, which is the most reliable way to identify them.

HANEL Occlusion Foil 12 μ
HANEL OccluFoil+ 12 μ
For precise occlusal adjustment The HANEL foil fulfils all the requirements needed for today’s gnathology. The biaxial characteristics of the foil ensure that it is highly tear resistant yet elastic. It is extremely fine and the precise colour transfer guarantees pinpoint markings on high spots.
› extremely tear resistant › extremely thin › very pliable
› pinpoint marking of stops and microcontacts › non toxic colour layer › no smearing
The 22 mm wide foil is available in single-sided, double-sided one coloured and double-sided two coloured. For the 22 mm wide foil a practical dispenser is available with an integrated cutter. The 80 mm wide foil is available single-sided or double-sided one coloured in a practical box. › Lengthwise tear resistant › Extremely thin › Very pliable

Definitions Occlusion and Occlusal Interferences1 Occlusion: The static and dynamic contact b etween u pper and lower teeth Static occlusion: Contacts between teeth without movement in intercuspation Dynamic occlusion: Contacts between teeth occuring under movement of the mandible Centric occlusion: Static occlusion in centric related condyle position Maximal occlusion: Maximum contacts between teeth with static occlusion Habitual occlusion: Consistent relationship of teeth in maximum intercuspation Occlusal interference: Premature contact between a tooth or group of teeth in static or dyamic occlusion
Deflective occlusal contact: Tooth contact that d iverts the mandible from a n ormal path of closure to centric jaw relation, m oving the c ondyle to an e ccentric position in habitual o cclusion Traumatogenic occlusion: Tooth contact that d iverts the mandible from a normal path of closure to centric jaw relation, m oving the c ondyle to an eccentric position in habitual o cclusion CMD Syndrome: (craniomandibular dysfunction) › Headache › Hypersentisivity to light › Ear ache › Tinnitus › Sensitivity to noise › TMJ problems › Bruxism › Difficulties in swallowing › Neck pain › Shoulder pain
