Efficacy of Selective Grinding Guided by an Occlusal

30/06/2017· OBJECTIVE: This study aims to describe a reproducible, predictable and to date unreported procedure of selective grinding guided by an occlusal splint and to analyze condylar position (CP) based on the skeletal pattern. METHODS: A total of 72 symptomatic patients (38 females and 34 males) were classified into three groups: hyperdivergent, intermediate and hypodivergent. CP was

Efficacy of Selective Grinding Guided by an Occlusal

The selective grinding procedure is an irreversible process for reshaping teeth by accurately modifying specific areas of the crown according to a previously established pattern, in order to remove interferences and premature contacts. In the present study, once the condyles were seated, the use of the splint identified these premature contacts in MIC.

Occlusal adjustment by selective grinding and nse of an

When selective grinding is used to obtain occlusal equilibrium, skill in prognosticating desirable mor-phofunctional results (occlusal contact relationships and occlusal activity related to the lesion') is necessary because the goals and procedures are frequently dif-ficult: 1. Moving the mandible laterally {because of a lack of neuromtiscular relaxation) 2. Neuromuscular relaxation in the

Selective Grinding Scientific.Net

The selective grinding study shows that the separation by the particle size classification is difficult to improve the A/S ratio of concentrate mineral. Through the flotation experiments, the technological condition for improving the A/S ratio of diaspore by direct--flotation was discussed; the technological and economic indicators of the different beneficiation process were also compared. 299

A study on selective grinding as a prophylactic treatment in craniomandibular disorders was published in 1998 (Kirveskari et al., 1998). A sample of 146 patients was followed-up for 4 years. The study aimed at finding out the causal role of occlusal interferences operationally defined by Dawson. The adverse effects caused by the selective grinding were considered unfounded. This study

Occlusal management for a patient with aural symptoms

In the present study, the selective tooth grinding in the BPOP seemed to provide a "cure" for our patient who had vertigo, tinnitus and otalgia. Conclusion. An occlusal analysis should be carried out in patients with TMD-related symptoms to identify whether a discrepancy exists between the HOP and BPOP (the latter being regarded as a physiological reference position). If a discrepancy does in
