Journal of Esthetic and Restorative... Nov 2016Intraoral occlusal adjustment of ceramic restorations can create a significant increase in surface roughness that can produce wear of the opposing dentition.
PROBLEM
Intraoral occlusal adjustment of ceramic restorations can create a significant increase in surface roughness that can produce wear of the opposing dentition.
PURPOSE
To compare the surface roughness of glazed and polished monolithic ceramics with the surface roughness produced by different intraoral polishing systems on adjusted monolithic ceramics.
MATERIALS AND METHODS
Milled ceramic discs (10 mm diameter × 2 mm thickness) were manufactured and distributed according to the following groups (n = 10): BruxZir (glazed and polished), Zenostar (glazed and polished), IPS Empress CAD, and IPS e.max CAD. Surface roughness, expressed as arithmetic average height (R ), was measured using atomic force microscope and profilometer before and after adjustment and polishing with the following intraoral polishing systems: BruxZir and Dialite ZR (for BruxZir), Zenostar and Dialite ZR (for Zenostar), and OptraFine and Dialite LD for IPS Empress CAD and IPS e.max CAD. Mean and standard error for each material and polishing system were calculated. T-test, one-way ANOVA, and Bonferroni post hoc tests were used to analyze data.
RESULTS
BruxZir zirconia presented smoother surfaces with Dialite ZR system compared to BruxZir system, Zenostar zirconia shown smoother surfaces with Zenostar system compared to Dialite ZR system and IPS Empress CAD and IPS e.max CAD presented smoother surfaces with OptraFine system in comparison to Dialite LD system.
CONCLUSION
All materials presented smoother surfaces at baseline than after adjustment and polishing.
CLINICAL SIGNIFICANCE
This paper reveals the results of an in vitro study that provides information to clinicians regarding which intraoral polishing system will produce a smoother surface after the adjustment and polishing of IPS Empress CAD, IPS e.max CAD, BruxZir and Zenostar ceramic materials.

Comparative Study Randomized Controlled Trial
The purpose of the present study was to test the effect of elimination of occlusal interferences on the incidence of requests for treatment of symptoms in the head and cervicobrachial region. One hundred and twelve females 45 years of age or under, were randomly divided into a treatment group (n = 54) and a control group (n = 58). The former underwent occlusal adjustment and the latter grinding that did not affect occlusal contacts. The treatments were repeated every 12 months over a period of 4 years. The outcome variable was a spontaneous request for treatment. Statistical analyses included chi-square tests for categorical variables and a t- or Wilcoxon ranked sum test for continuous variables. Poisson regression was used to compare the risk of seeking treatment between the groups. The cumulative incidence rate of treatment requests was 2/54 in the treatment group and 11/58 in the control group. The relative risk was 5.12. The 95 per cent confidence limits were 1.14 and 23.1, respectively. The difference between groups was statistically significant (P = 0.0336). Systematic elimination of occlusal interferences significantly reduced the incidence of requests for treatment of symptoms in the head and cervicobrachial region. This is in contrast with the view that there is no, or at best, an insignificant health risk from occlusal interferences.

This article describes a procedure in which articulating paper is modified for the intraoral assessment of static occlusal contacts. The rectangular-shaped articulating paper is modified by creating parallel cuts at 2- to 3-mm intervals perpendicular to its long side without completely separating the paper. This modification may improve the accuracy in determining occlusal contacts and therefore facilitate an occlusal adjustment procedure.

Review
The second part of this review, evaluating the literature on the relationship between dental occlusion and temporomandibular disorders (TMDs), focuses on the aetiological importance of tooth loss and the place of prosthodontic replacement in the treatment of TMD. Loss of teeth and lack of posterior occlusal support seem to have little influence on the development of TMD, which calls into question the use of prosthodontic restoration as prevention or treatment for TMD. In addition, there are practically no studies assessing the benefit of instrumental analysis in diagnosis or comparing the outcome of prosthodontic treatment with simple reversible methods in the management of TMD. There is a trend in the current literature to abandon any treatment, including positioning appliances and prosthodontic measures, to 'recapture the disk' in patients with disk displacements because of the favourable, long-term results achieved after using more simple methods. It is concluded that prosthetic therapy in TMD patients is not appropriate for initial TMD treatment and should only be carried out on prosthodontic indications after reversible treatment has alleviated pain and dysfunction.

Review
Food impaction with tight proximal contacts, also known as kinetic food impaction and food impaction without anatomical structure destruction, is mainly caused by a transient separation in contacts area during mastication. It's an intractable food impaction with high morbidity and low cure rate. There are two kinds of pathogenesis accepted: the shifting of anterior teeth incongruous with adjacent teeth or lack of anterior shifting; lack of food escape grooves. The preferred treatment is occlusal adjustment, but it's difficult to determine the area and extent of selective grinding, to quantify the occlusal adjustment, or to predict the prognosis. This review summarized the pathogenesis and treatment modality for kinetic food impaction in order to provide evidence for future researches and clinical application.

Clinical Trial Comparative Study Randomized Controlled Trial
The aim of this study was to evaluate the effect of occlusal adjustment in a prospective longitudinal study. Fifty selected patients with craniomandibular disorders (CMD) including headaches were randomly assigned to a treatment (T) or a control (C) group. Both groups received counselling and occlusal adjustment was performed in T group. Subjective symptoms and clinical findings were registered before and 2 years after treatment. At a follow-up 48% in the T group and 84% in the C group had demanded rescue treatment. Eleven patients in the T group (48%) and 3 patients in the C group (13%) without rescue treatment, reported overall subjective improvement. No difference was found between the groups regarding overall intensity of pain expressed by the visual analogue scale. When all kinds of treatment were taken into account, 70% and 79% of the patients in the T and C group reported overall subjective improvement at follow-up. The conclusions from this study were that in a two-year perspective only single patients improved from counselling alone. A few more patients improved if one more kind of treatment, for example occlusal adjustment, was added to the initial counselling, but the majority of the patients required a comprehensive treatment program.

The Journal of Prosthetic Dentistry Nov 1999An inordinate amount of time is often required to adjust the occlusion of a newly fabricated crown. (Clinical Trial)
Clinical Trial Randomized Controlled Trial
STATEMENT OF PROBLEM
An inordinate amount of time is often required to adjust the occlusion of a newly fabricated crown.
PURPOSE
This study determined whether the procedure of "cast adjustment" significantly decreases the time necessary to clinically adjust the occlusion of a newly fabricated crown.
MATERIAL AND METHODS
Thirty-eight crowns were fabricated by a commercial dental laboratory for patients of senior dental students at the University of the Pacific School of Dentistry. After master casts were returned from the laboratory and then mounted on semiadjustable articulators by the students, the cases were divided randomly into 2 groups: (1) the control group, for which no further work was performed before fabrication of the restoration; and (2) the experimental group, in which casts were occlusally adjusted by a certified laboratory technician until there was at least 1 cusp tip to flat surface centric contact on each posterior tooth in maximum intercuspation position. After the crowns were delivered, the students filled out a survey. One question on the survey asked the student for the time required to adjust the occlusion on the crown.
RESULTS
Of the 19 crowns in the control group, 6 crowns required more than 1 hour for occlusal adjustment. Of the 19 crowns in the experimental group, 1 crown required more than 1 hour for occlusal adjustment.
CONCLUSION
Performing a "cast adjustment" before fabricating a single unit casting can significantly decrease the chance of a lengthy clinical occlusal adjustment.
