Study of a New Technique to Improve the Symptoms of Orofacial Discomfort in Patients With Peripheral Facial Paralysis

Summary

* The purpose of this study was to evaluate the effects of Neuro Occlusal Rehabilitation (RNO) in patients with peripheral facial palsy (PFP) disease, noting the decrease in symptoms of masticatory dysfunction.
* According to Carvalho (2009) patients with PFP have chronic unilateral masticatory preference. Santos et al. (2009) in the same year noted that these conditions can lead to problems with temporomandibular disorder.
* Hypothesis- known that performing occlusal adjustment in these patients with chronic PFP, ensuring a maximum of dental contacts and a final stop of the masticatory cycle stable, providing a balanced occlusion.
* dental cleaning was performed in two groups for the blind study
* visual analog scale -To assess the quality of the oral functions of these patients, the investigators applied the visual analog scale(VAS) and statistically evaluated the degree of satisfaction regarding the functions of oro facial in relation to mastication and temporomandibular dysfunction.
* gnathostatic models were made in the treatment group in the first and last query.
* occlusal adjustment in treatment group.In the group treated occlusal adjustment was made in the teeth and applied a new (VAS) before and after treatment.

The RNO, is defined as a part of medicine that operates in stomatology occlusal plane as a guide to a harmonious development of the face, chewing facilitating bilateral and alternating. (Planas, 1997). It works through selective grinding on the occlusal platform, providing an increased number of dental contacts.

Conditions

• Peripheral Nerve Facial Nerve Paralysis
• Facial Nerve Diseases
• Orofacial Pain

Interventions

PROCEDURE

occlusal adjustment.

It prompted the patient to perform the act of swallowing for 3 times to reach a terminal axis of rotation of the jaw and from this to start. Will be held palpation of the muscles, masseter and temporal on both sides and compared with the marks of carbon found in the teeth. After starts the adjustment following the rules of Guichet with a cylindrical drill with a thin cut . basic principles 1 Occlusive stress maximum distribution in centric relation 2 The occlusive strengths should by the teeth's major axis.3 When the contact is surface to surface, it must be exchanged to another surface point. 4 Once the stability to the centric relation is achieved, it should be kept. The rules to guide the occlusal adjustment selective grinding .

BEHAVIORAL

Visual analog scale.

Visual analog scale-Graduation was held on the visual analogue scale in the first and last query to measure discomfort chewing.Graduation was held on the visual analogue scale .in the first and last query to measure discomfort chewing. After graduating dental cleaning was performed, with the purpose of blinding the study, Dental Cleaning.With engine using low speed, brushes, and prophylactic paste is carried out dental cleaning in the teeth of all patient. Dental Cleaning.With engine using low speed, brushes, and prophylactic paste is carried out dental cleaning in the teeth of all patient.
