Journal of Oral Rehabilitation May 2020The diagnosis and management of patients suffering from occlusal dysesthesia (OD) remain a major challenge for dental practitioners and affected patients.
BACKGROUND
The diagnosis and management of patients suffering from occlusal dysesthesia (OD) remain a major challenge for dental practitioners and affected patients.
OBJECTIVES
To present the results of a literature-based expert consensus intended to promote better understanding of OD and to facilitate the identification and management of affected patients.
METHODS
In 2018, electronic literature searches were carried out in PubMed, Cochrane Library and Google Scholar as well as in the archives of relevant journals not listed in these databases. This approach was complemented by a careful assessment of the reference lists of the identified relevant papers. The articles were weighted by evidence level, followed by an evaluation of their contents and a discussion. The result represents an expert consensus.
RESULTS
Based on the contents of the 77 articles identified in the search, the current knowledge about clinical characteristics, epidemiology, aetiology, diagnostic process, differential diagnosis and management of OD is summarised.
CONCLUSIONS
Occlusal dysesthesia exists independently of the occlusion. Instead, it is the result of maladaptive signal processing. The focus should be on patient education, counselling, defocusing, cognitive behavioural therapy, supportive drug therapy and certain non-specific measures. Irreversible, specifically an exclusively dental treatment approach must be avoided.

INTRODUCTION
An increase in life expectancy was observed in the past years. Consequently, the knowledge of the maturational changes in the occlusion is highly important to guide clinicians during treatment planning.
OBJECTIVE
In this article, the occlusal and facial aging changes occurred during almost 50 years of follow-up are described. A normal occlusion sample from Bauru Dental School, University of São Paulo, Brazil, was evaluated at 13 (T1), 17 (T2) and 60 (T3) years of age. The maturational changes observed in digital dental models and cephalometric radiographs were presented. A revision of the aging process, under the gerontology and psychology perspectives, was also explored.
DISCUSSION
Maturational changes in non-treated individuals were very delicate. Mandibular crowding, decrease in the overbite, changes in the maxillary second molar position, increase in the clinical crown length, dental wear and discoloration were observed.
CONCLUSION
Compared to the remarkable facial and skin changes during aging, the occlusion seems to be the most stable feature of the face during the aging process.
FINAL CONSIDERATIONS
An adequate oral care throughout lifetime makes the smile the best memory of youth at mature ages.

AIM
To determine if there are differences between the dental arch dimensions and occlusal characteristics of children born prematurely and admitted into a Neonatal Intensive Care Unit (NICU) (study group) and children born at term (control group). The study group was analysed at the same time in order to find out if the parameters of the dental arches are related to specific perinatal variables.
MATERIALS
Study design: Out of a total of 504 children born between 2011 and 2014 in high-risk conditions at the clinic of the University Hospital "San Cecilio" in Granada (Spain), 78 children were selected. Of these 42 had been born prematurely and admitted to the NICU (study group) and 36 had been born at term (control group). The age of the sample was 5 to 8 years. The parameters of the dental arches, together with the occlusal characteristics, were examined using dental casts. Both the upper and lower arches were measured for a total of 156 dental casts with a FINO digital caliper.
CONCLUSION
The data confirm the smaller size of the dental arch dimensions of children born prematurely and admitted to a NICU compared with children born at term. This fact should be taken into consideration with regard to future orthodontic and paediatric dentistry treatments.

Review
The straight-wire appliance is an individualized, fully-programmed appliance system that has been in clinical use since the early 1970s. A study of tooth positions in individuals with naturally occurring harmonious occlusions led to the discovery of the Six Keys to Normal (Optimal) Occlusion which provided data for bracket features and prescription values incorporated into the straight-wire appliance. It was based on the notion that tooth anatomy, morphology, and optimal positions were alike enough among individuals, regardless of age, sex, or race to justify using prefabricated brackets with average prescription values. New technologies have led to advancements in appliance customization. Customized brackets can be made-to-order with one-of-a-kind prescription values and bracket base contours that fit precisely to the morphologic characteristics of the teeth. If costs and material qualities were comparable, would treatment efficiency or treatment outcomes be superior when using a customized appliance compared with a prefabricated straight-wire appliance? If not, why not?

OBJECTIVE
Occlusal splints are always applied on individuals with bruxism to reduce tooth wear and relieve orofacial symptoms such as myofascial pain. The stomatognathic system is mainly composed of tooth, occlusion, masticatory muscles, and temporomandibular joint. The occlusion and masticatory muscles function are regarded as the important parameters for evaluating the stomatognathic system state objectively. However, the effects of occlusal splints on individuals with bruxism is rarely elucidated from accurate neuromuscular analysis and occlusion evaluation. The aim of the present study was to estimate the effects of three different splints (two clinically common full coverage occlusal splint and an modified anterior splint) on subjects with bruxism using K7-J5 neuromuscular analysis system and Dental Prescale II (DP2) to evaluate occlusion.
METHODS
Sixteen subjects claimed to be suffering from nocturnal bruxism,with complete dentition and stable occlusal relationship, were selected for study.The intermaxillary space and the baselines of EMG-activity of the anterior temporalis and masseter were recorded for all the subjects. The participants was treated with three different splints, and outcomes were estimated by comfort index, occlusion and surface electromyography of anterior temporalis and masseter.
RESULTS
At teeth clenched position, EMG data were significantly lower in the participants with use of modified anterior splint than with hard, soft occlusal splint or without splint (p < 0.05). The maximum bite force and bite area occur in subjects without use of splint, while the minimal occur in subjects with use of modified anterior splint. Intermaxillary space increased and masticatory muscles presented significant reduction of EMG data at rest position as a result of J5 (p < 0.05).
CONCLUSION
Modified anterior splint seems to be more comfortable and effective in reducing occlusion force and electromyographic activity of anterior temporalis and masseter for subjects with bruxism.

AIM
Dental occlusion often rhymes with confusion, discrediting many research protocols. The profession seems to be in "major chaos about occlusion." This may be due to the lack of a precise classification of occlusal dysfunctions. We suggest using a classification based on the separation of three occlusal functions, with the identification of precise, objective clinical diagnostic criteria. This article aims to define a precise classification of occlusal functions, in order to be able to establish a positive diagnosis of occlusal disorders. This occlusal analysis method could then be used in the daily practice of dentists and orthodontists, with a view to align epidemiological studies that focus on occlusion, in order to obtain results capable of comparison in different studies.
MATERIALS AND METHODS
A analysis of the literature in PubMed database published between the early 1970s and the present day identified many confusing definitions of occlusal disorders. In this paper, we propose the separation of occlusal functions into three subcategories: Stabilizing, centering, and guiding functions, defining three different subcategories of occlusal disorder.
RESULTS
Occlusal function allows the definition of three kinds of malocclusion: Stabilizing dysfunction, centering dysfunction, and guiding dysfunction. The individualization of clear subcategories could allow the study of the more pertinent impacts of pathogenic malocclusion.
CONCLUSION
This classification of occlusal functions or dysfunctions allows lines to be drawn between different occlusal situations that are frequently confused, such as a loss of posterior occlusal support and loss of occlusal vertical dimension, infra-occlusion and loss of posterior support, short or reduced dental arch, reversed and scissor occlusion, sagittally and transversely deflected mandible, posterior occlusal interference and balancing contact, as well as natural and iatrogenic malocclusion.
CLINICAL SIGNIFICANCE
An occlusal analysis that makes use of the three occlusal functions, "stabilizing, centering, guiding," could offer diagnostic standardization. It may also allow the avoidance of incorrect interpretations. Therefore, this occlusal function classification may be relevant to many fields, for instance, for epidemiological studies of occlusion and the periodontium, TMD and occlusion, or TMD and orthodontic treatment.

Review
: The purpose of the present review was to demonstrate the utility of articulator systems and link instrumentation in determining the occlusal plane. The impact of the natural head position and anatomical landmarks on the occlusal plane location has been reported in the literature. Properly chosen instrumentation and management methods eliminate errors in determining the occlusal plane.: The PubMed and the Dentistry & Oral Sciences Source (through EbscoHost) databases were searched for ways to minimize the occurrence of errors when registering and determining the occlusal plane location, with or without the use of face-bows. A hand search and citation mining supplemented the results.: Overall, 11 original approaches to occlusal plane determination were identified.: Identified methods of occlusal plane transfer are based on real or virtual solutions. Owing to the large variety of devices, additional comparative studies are needed.
