Introduction: Occlusal splints are usually the first choice in the treatment of bruxism. Splints can also be the only treatment or can be ended with adhesive restoration, orthodontic or prosthetic treatment. Methods: This article demonstrates the steps of a digital workflow through the 3Shape Design system - splint studio. The initial units are virtual models, scanned by Trios Color Scanner (3Shape). Results: The digital protocol includes eight steps that allow precise and detailed creation of the searched object. Each step is described from the perspective of a clinician, prosthetist and orthodontist, not a dental technician. Possible complications and ways to management with them are described. Conclusion: Digital protocol of occlusal splint creation gives many opportunities according to design, thickness and occlusion.

Occlusal splints (Michigan splints, night/bite guards or bite-raising appliances) can be an effective, inexpensive and reversible treatment for a wide range of dental problems. Objective The aim of this study was to analyse retrospectively the provision of occlusal splint (‘Michigan’ type) in general dental practice, following a prescription by a restorative dental consultant. Method One hundred patients were recruited from consultant clinics in a department of conservative dentistry during 1995 and 1996. All patients were prescribed a maxillary, full-coverage, heat-cured, acrylic-resin splint (Michigan splint) as part of a treatment plan. An explanatory letter and questionnaire were sent to all patients and to their referring general dental practitioner in 1997 and 1998. Results A response rate of 79% was achieved in obtaining completed questionnaires from both patients and general dental practitioners. Of respondents 43% (34/79) received an occlusal splint of some form. A small proportion of the respondents (16.5% [13/79]) received a Michigan splint as prescribed. Irrespective of the type of appliance provided, most patients (82% [28/34]) found them helpful. Of those who did not receive an occlusal splint, 38% (17/45) of patients felt financial implications deterred them from obtaining an appliance. Other common reasons for non-provision included: patients felt that symptoms had improved (18% [8/45]) and patients did not agree with treatment (18% [8/45]). The general dental practitioners had similar opinions to their patients. Discussion These findings raise some serious doubts on the efficacy of consultant clinic advice in the prescription of occlusal splints in general dental practice. The financial and educational issues raised by this study will need to be addressed to improve service provision. Conclusion The results of this study indicate that 16.5% of patient respondents prescribed a Michigan splint at a consultant clinic received such an appliance in general dental practice.

The Impact

The aesthetic treatment for anterior teeth requires a series of clinical and technical evaluations to obtain a predictable result, following a well-defined operating sequence. Today, the clinical–technical team can use different digital tools in the different steps of the workflow. A preventive assessment, the knowledge of limits, and the possibilities of surgical and prosthetic procedures allow to use these devices. Sharing goals of the treatment with the patient according to their expectations and needs is the key point of the treatment plan. Setting a defined treatment plan avoids invasive procedures. In this clinical case report, a 27-year-old patient affected by Class II div 2 malocclusion with deep bite was treated with a full digital workflow. Previewing the aesthetics was through dedicated software, which shows operators and patients the objectives of the therapy and guides the dental technician in the first phase of the work. The use of digital flows in the prosthetic phases reduces the working time. In this case, it shows the impact of a digital workflow on peri-prosthetic therapy for the aesthetic rehabilitation of the upper central incisors in a young adult.

Occlusal Interferences

Occlusal splints are used to protect teeth, relieve orofacial pain, and preview the patient response to a simulated occlusal correction. This chapter outlines proper occlusal splint fabrication that employs T-Scan analysis to verify a therapeutic occlusion. The T-Scan provides objective relative occlusal force and timing data that guides the refinement of a splint's occlusal scheme. Therefore, this chapter explains adjusting an occlusal splint's contact pattern with ink ribbon followed by the T-Scan. It also addresses the controversy regarding the existence of, or lack thereof, a relationship between occlusal interferences and masticatory muscle dysfunction. The author postulates that the research studies that argue against the existence of a relationship are absent of occlusal measurement and lack a scientific basis to deny a relationship exists. Lastly, recommendations are made to include the T-Scan in Temporomandibular Disorder treatment studies with both occlusal splints and natural teeth, so that researchers might resolve this controversy for dental clinicians.

Muscles Of Mastication

Previous studies have shown a significant higher prevalence of craniomandibular dysfunction (CMD) in violin players compared with controls. CMD is related to increased muscular load in the muscles of mastication, the trapezius and sternocleidomastoid muscles, which can possibly predispose to overuse syndromes. To examine whether CMD can also cause overuse syndromes in violinists, we investigated a group of 31 violinists by questionnaire, mandibular tracking, and a clinical examination to elicit overuse and CMD symptoms. The influence of CMD on muscular tension during violin playing was assessed with surface EMG; this was performed twice on each violinist, once with and once without an occlusal splint, in order to work out the effect of CMD on the muscular load. CMD could be diagnosed in 74% of the investigated violinists. The occlusal splints significantly decreased the load in the masseter, temporalis, trapezius, and sternocleidomastoid muscles during musical performance. Occlusal splints appear to decrease the muscular load in asymptomatic violinists as well, suggesting a possible preventive and therapeutic role in overuse symptoms in the setting of preexisting CMD.

A clinically similar entity to classical migraine is seen in certain dental patients suffering from temporomandibular joint (TMJ) pain dysfunction syndrome. Patients selected for study gave symptoms of classical migraine on waking. Facial pain on waking is typical of some cases of TMJ dysfunction syndrome and the hypothesis was tested that some patients with symptoms of classical migraine were at the extreme end of the spectrum of dysfunction syndrome. However, rather than experience muscle or temporomandibular joint pain these patients had symptoms on waking which were typical of classical migraine. Nineteen patients with migraine symptoms were provided with acrylic occlusal splints for nocturnal wear. A good clinical response with considerable reduction in frequency and severity of pain attacks was achieved.

Subject. Syndrome of pain dysfunction of the temporomandibular joint is one of the common pathologies of TMJ. Patients with this diagnosis complain of a violation of the movements of the lower jaw, discomfort and pain in the joint. The writings of many authors contain a deep and comprehensive discussion of various aspects of this problem, and scientific justification is given that TMJ dysfunction is almost always accompanied by muscle symptoms. One method of treatment is the use of occlusal splints. In this regard, the task of determining the effectiveness of eliminating muscular-articular dysfunction using individual occlusal splints is relevant. The aim of the study was to determine the effectiveness of treatment of TMJ dysfunction with occlusal splints according to kinesiography. Methodology. The kinesiographic study on the Myotronics K7 apparatus consisted of sequentially performing functional tests (opening and closing the mouth, lower jaw movements to the side) and using the method of percutaneous electroneurostimulation. In the treatment of all patients, an occlusal positioner splint was used, which was made individually in an articulator using an interocclusal register in the neuromuscular position of the lower jaw. The average treatment period was 4.5 months with monthly adjustments to the occlusal splint. Results. As a result of treatment with the use of the occlusal splint, disturbances in the trajectory in the transverse (in 70 % of cases) and sagittal (in 65 % of cases) planes were eliminated, the position of the lower jaw in the neuromuscular position (in 100 % of cases) was normalized. Conclusions. Treatment of patients with TMJ dysfunction using individual occlusal splints is one of the most effective ways to treat this pathology.

Abstract Conservative approach, including occlusal splint therapy, is the first option to treat temporomandibular disorders (TMD), because of its reversibility. The present study analyzed the effect of the articular disc position and occlusal splints use on the stress distribution on this disc. A two-dimensional (2D) finite element (FE) model of the temporomandibular joint with the articular disc at its physiologic position was constructed based on cone-beam computed tomography. Three other FE models were created changing the disc position, according to occlusal splint use and anterior disc displacement condition. Structural stress distribution analysis was performed using Marc-Mentat package. The equivalent von Mises stress was used to compare the study factor. Higher stress concentration was observed on the intermediate to anterior zone of the disc, with maximum values over 2MPa. No relevant difference was verified on the stress distribution and magnitude comparing disc positions and occlusal splint use. However, there was stress reduction arising from the use of the occlusal splints in cases of anterior disc displacement. In conclusion, based on the generated FE models and established boundary conditions, the stress increased at the intermediate zone of the TMJ disc during physiological mandible closure. The stress magnitude was similar in all tested situations

The efficacy of occlusal splints in diminishing muscle activity and tooth-grinding damage remains controversial. The objective of this study was to compare the efficacy and safety of an occlusal splint (OS) vs. a palatal control device (PCD). Nine subjects with sleep bruxism (SB) participated in this randomized study. Sleep laboratory recordings were made on the second night to establish baseline data. Patients then wore each of the splints in the sleep laboratory for recording nights three and four, two weeks apart, according to a crossover design. A statistically significant reduction in the number of SB episodes per hour (decrease of 41%, p = 0.05) and SB bursts per hour (decrease of 40%, p < 0.05) was observed with the two devices. Both oral devices also showed 50% fewer episodes with grinding noise (p = 0.06). No difference was observed between the devices. Moreover, no changes in respiratory variables were observed. Both devices reduced muscle activity associated with SB.

The aim of this study was to develop and evaluate a digital process for manufacturing of occlusal splints. An alginate impression was taken from the upper and lower jaws of a patient with temporomandibular disorder owing to cross bite and wear of the teeth, and then digitized using a table laser scanner. The scanned model was repaired using the 3D ata E xpert software, and a splint was designed with the V iscam RP software. A splint was manufactured from a biocompatible liquid photopolymer by stereolithography. The system employed in the process was SLA 350. The splint was worn nightly for six months. The patient adapted to the splint well and found it comfortable to use. The splint relieved tension in the patient's bite muscles. No sign of tooth wear or significant splint wear was detected after six months of testing. Modern digital technology enables us to manufacture clinically functional occlusal splints, which might reduce costs, dental technician working time and chair-side time. Maximum-dimensional errors of approximately 1 mm were found at thin walls and sharp corners of the splint when compared with the digital model.
