Compensating curve

I would like each of you to give me your understanding of what the role is of the compensating curve is, when setting the posterior teeth in balanced occlusion. You are not to copy-paste from textbooks and do not repeat another students comments.

  1. in my opinion when setting the teeth for a full/full denture I would set the teeth with the compensating curve for aesthetics reasons in terms of the smile line. upon further research i have found that it is used to compensate for the movement of the condyles.

  2. I would say it is determined by the inclination of the posterior teeth and their vertical dimension to the occlusal plane therefore, this will result in a curve which in turn will harmonise with the condyle path movement.
    The main function of a compensating curve is to provide balancing protrusive contacts for protrusive mandibular positions. This curve is determined by the curve of spee and curve of monson relation.
    Without this curve that means there would be a need to incline the whole occlusal plane at an angle. Therefore, the result of this would raise the lower occlusal plane on the distal which will also alter the relationship of the occlusal plane of the maxila and mandible. By altering the occlusal plane inclination to an increased anteroposterior angle may favour the stability of the mandibular denture due to the resultant forces of the inclined planes

  3. the role of the comp curve is so that you have simultaneous uninterupted bilateral contacts on your anterior and posterior teeth when you create excursions on ur artiulator. when u dont have a good comp curve, u will struggle to achieve bilateral balanced occlusion. the use of a comp curve plate is useful and will allow u to gain balancing contacts automatically.

  4. This is the curvature of alignment of occlusal surfaces of posterior teeth that is developed to compensate for the paths of the condyles as the mandible moves from centric to eccentric position.This curve is determined by the posterior teeth and their vertical relationship to the occlusal plane so that the occlusal surface results in a curve that is in harmony with the movement of the mandible guided posteriorly by the condylar path.

    It is one of the detrimental factors of balanced occlusion. In short, the compensation curve is obtained by setting the posterior teeth in a curve of Spee and curve of Monsoon. A steep condylar path requires a steep compensation curve for a balanced occlusion.
    However though a shallow compensation curve would result in a steeper incisal guidance which causes a loss of molar balancing contacts.

  5. The role of the compensating curve in achieving balanced occlusion is very important and very simple. As the cusp angel of the posterior teeth increase, so should the angle of the compensating curve (monoplane teeth = flat compensating curve; anatomical teeth = more angled compensating curve). This is due to the fact that cusp angles influence the angle of lateral excursions.

  6. the compensating curve is important in complete dentures, in my opinion when one masticates the lower jaw moves in a gliding motion, be it lateral, bilateral etc. The compensating curve in dentures helps create that motion when the lower jaw goes into all the eccentric and centric movements. it aids in restoring the natural jaw relations and functional movements the patient had. if one does not restore this, it would create disharmony when the patient attempts what one would consider as normal jaw movements. the compensating curve inclines along with the occlusal plane and it affects the occlusion and functionality of the wear. when it comes to the purpose of a denture, the functionality should be our first priority.

  7. The compensation curve can be defined as the anteriorposterior and lateral alignment of the occluding surfaces and incisal edges of artificial teeth, which is used to develop balanced occlusion.

  8. A compensating curve is the anteroposterior and lateral curvature in the alignment of the occluding surfaces and incisal edges of artificial teeth which is used to develop balanced occlusion.

    The form of the compensating curve is entirely under the control of the technician. The value of the compensating curve is that it allows the technician to alter the effective cusp angulation without changing the form of the manufactured denture teeth. By inclining the long axes of the teeth, the technician is able to arrange the cusp angulations so that they harmonize with the end controlling factors and create a balanced occlusion. (The extreme example would be tilting of cuspless teeth to create a compensating curve and provide for bilateral balance. In essence, cuspless teeth have been arranged so that they have an effective cusp angulation.)
    It is important to note that there are two components to a compensating curve. The anteroposterior curve is useful in creating balance in protrusive excursions while the cross-arch curve is more intimately involved in providing for balance in lateral movements

  9. Well done on that explanation mam, Good way of explaining all that stuff you just explained. That is correct!!
