Official Title: Neuro Occlusal Rehabilitation in Patient With Peripheral Facial Paralysis - a Randomized Clinical Trial

Brief 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.
  • gnathostats 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.


Detailed Summary:

Purpose: To evaluate the effects of the Neuro-Rehabilitation occlusion in patients with chronic facial palsy by observing the decrease of the symptoms of masticatory dysfunction.

Methods: a selection of sixty-five patients with facial palsy (PFP 65) and idiopathic chronic trauma of the Otorhinolaryngology sector facial nerve disorders at UNIFESP.

Patients were of both genders, aged between 18 and 60. They were analyzed according to the criteria of inclusion and exclusion, resulting in forty-three patients.

However, due to problems inherent in research, a group of fourteen patients were randomized (sub-divided) into two groups: control and treatment.

The visual analog scale was used at the first consultation to patients in the control and treatment All patients underwent a dental cleaning in order to blind the study. Seven patients belonged to the control group for three months, the VAS was performed in both groups. The control group was later reunited with the treatment group after three months of control period, increasing the number of patients who were examined in extracts, with similar features in a prognostic factor.

  • Control group
  • First visit-visual analogue scale and tooth cleaning
  • Second consultation, after a month, a new visual analog scale.
  • Third-query-one months after a new visual analogue scale patient was a three visits with an interval of one month, performing a repeat procedure.
  • Treatment group, The researchers applied the technique of Rehabilitation and Neuro Occlusal gnatostaticos models tha

    Current Primary Outcome: Visual analogue scale (VAS) [ Time Frame: The outcome measure (VAS) will be assessed approximately ninety days after the first query. ]

    It is a scale-shaped ruler, which is associated with faces used to grade the degree of pain for patients, before and after treatments, or just graduating pain and its severity for the patient (Souza, 2002).

    Patients were asked to fill the VAS with the following questions.

    • Do you chew well?
    • How would you classify your chewing at the moment?
    • If you have trouble chewing, the rating is zero.
    • If you have any discomfort when you chew, your reference level is five.
    • If the discomfort is intense, its reference level is ten. The greater the discomfort, the greater the scale.


    Original Primary Outcome: Same as current

    Current Secondary Outcome: Brand carbon count on gnathostats models [ Time Frame: The outcome measure will be evaluated after ninety days from the first consultation ]

    The models were placed occluding brought with carbon, using the willis compass to keep occluding the posterior base of the model which are aligned with the rear.

    The dental contacts were evaluated in models and gnathostats demarcated after the points were counted in the models before and after treatment If an increase in the number of dental contacts after occlusal adjustment was detected, in relation of the models.

    The models are made in the first and last query, after three visits with one month interval between them by adding three queries.



    Original Secondary Outcome: Same as current
